Thank you so much to Sergio and his team! We contracted OSH Construction to build an ADU, and working with them was such a great experience from start to finish! They demonstrated the utmost professionalism and integrity. They were reliable, hardworking and so kind. From the beginning, Sergio was very communicative and would send us updates on the project regularly. Him keeping us updated was very appreciated as it was our first big project and we knew exactly what to expect. If any challenges came up, Sergio would always share thoughtful and affordable solutions. Israel, Juan and the rest of the team were the sweetest group and would always go above and beyond. You can tell they care about the quality of their work. The team finished our project in just a few months and we are so happy with the results. It is an absolutely beautiful and functional space. In addition to the excellent customer service, the dedication to our project, and the timeliness, the project was fairly priced! Finding OSH Construction was truly a blessing. For any future projects, Sergio is the first person we will call! read more

Thank you Sergio, Ramon, and crew for the excellent work building our deck and stairs. Not only is your work first class, you show up when you say you will and leave a very tidy work area. Many many thanks. read more

Of all the many reviews I have written, this company would be at the very "top of all my ratings"!! Sergio and OSH Construction is by far, my most pleased of services, particularly when it comes to home remodels! I discovered Sergio after I saw his incredible work/remodeling to the house next door to me. We arranged our first meeting whereby he bought his laptop, and provided numerous options and designs for my bathroom remodel. Fortunately, Sergio has great ideas and suggestions, making the process of decision making, ie. what materials to use, design options, etc. The process started right on cue, and the ETA for completion of 4-5 weeks was righty on the money! The guys that work for OSH are ALL exemplary, professional, prompt, and courteous! From the demolition guys, the carpenters, the electrician, the painter, the glass guys, I could not have asked for better! The thing that stands out for me, is the fact that these guys were consistently prompt, and did not skip a beat. Unlike most contractors, whereby days are missed, job gets delayed due to spreading themselves too thin with other jobs. None of that with Sergio, he was spot-on prompt with moving this job along as scheduled. My bathroom remodel also included a steam-shower installation, which took on extra diligence, but well worth it! This remodel has improved my home, as if it were a complete add-on to my house, considering I rarely used this guest bathroom (even though it is adjacent to my office). To all the Yelp audience reading this, trust me, you could not get a greater, more skilled and considerate Contractor than Sergio and OSH! I cannot recommend him enough, and I guarantee you will appreciate this review once you hire him. *** Take the time to review all of my photos that show the step-by-step process for this job! Also note that I used "single slab" porcelain, for my shower, versus individual tiling. This process was a much more challenging and labor intensive install, but well worth it, and Sergio's team pulled it off perfectly!! read more

We recently finished a full kitchen and bathroom remodel, and we couldn't be happier with the results! As a family with four kids and two dogs, we needed a team who understood real-life chaos--and they absolutely did. From the very beginning, they were patient, organized, and genuinely committed to creating a space that would work for our busy household. While we were moved out during the remodel, Sergio kept us updated every step of the way. We always knew what was happening, what was coming next, and if anything required a decision. That communication alone made the whole experience so much less stressful. They also worked around our constantly changing schedules without ever making it feel like an inconvenience. The craftsmanship is excellent we loved working with Israel for his beautiful cabinetry, ideas, and details. The clean tile work is beautiful! Our finished kitchen is everything we hoped for. It's bright, functional, and truly fits the way our family lives. We could not be happier. If you're looking for a contractor who delivers high-quality work and makes the process smooth for a busy family, I can't recommend them enough. Sergio and his team are truly amazing. read more

OSH Construction - General Contractors Near Me - Garden Grove, California

HIGHLY RECOMMEND: Sergio and his team are so easy to work with, very communicative, and as evident from the pictures, did an amazing job updating our midcentury home that was stuck in the 70s. One thing you'll notice with the other reviews is that folks have checked out multiple other general contractors and OSH Construction keeps coming out on top. The same happened here where we asked multiple contractors to survey the work and bid for our full house reno (floors, walls, lighting, kitchen, bathrooms). When Sergio walked with us to survey, he asked the right questions, made great observations, and was genuinely personable. When it came to pricing, he was fair and within the ballpark of other contractors. He's thorough when putting together the quote so it may take time some time. Trust, he didn't forget about you. At decision time, it came down to choosing between him or the contractor that our families had worked with/recommended. The difference was the person; we felt like Sergio would be more responsive and not keep us wondering about the progress. We had a good feeling about him! The PROCESS: Man, his team was fast! We made the decision on a Wednesday. They came in that following Monday to demo and were starting on electrical by Wednesday. Sergio met with us every 1-2 weeks to do walkthroughs and talk about next steps, and we received daily text updates on what was accomplished for the day, which we greatly appreciated and felt involved. When looking for a general contractor, whether or not they use sub-contractors impacts the schedule and the pricing. Sergio has his own trades teams; they're a full construction company. For those trades that his team doesn't do (stair railings, glass shower doors), he has some great recs. Now that we're enjoying our new home, we will be sure to look to Sergio and OSH Construction for future work and keep singing his praises to friends/family looking for recommendations! read more

Sergio and his team absolutely blew me away. The quality of their work and attention to detail is top notch. We experienced a water leak that resulted in a kitchen rebuild, drywall installation, new stairs, as well as floors throughout. Sergio saw that we had been dealing with the issue for many months and made a commitment to a 3-week timeline. When his crew showed up the next Monday morning, I actually believed it might happen. Sure enough, they arrived every morning no later than 8 am, knew exactly what needed to be done, and demonstrated the most incredible work ethic I've ever seen. Not only did they get the job done, but they also tackled a series of challenges that cropped up along the way and took on extra tasks that we had been really hoping to do. I almost can't believe how lucky we were to find Sergio and OSH Construction. Working with contractors and home repairs is far outside my comfort zone, and we'd had some bad experiences in the past, so I was really dreading all the stress of this rebuild. But working with Sergio is honestly so easy. It feels like you are on the same team, which seems like it should be a given but, in truth, is so hard to find. When I reflect on the qualities and characteristics of Sergio and the OSH team, this is what comes to mind: 1. Excellent, thoughtful craftsmanship. 2. Reliable, dependable, and consistent. 3. Hard-working, efficient, and skilled. 4. Professional, kind, helpful. 5. Communicative, clear, and honest. I will be recommending OSH to everyone I know. I am so thankful for the work they did on our home. Everything looks beautiful and it means so much that I can close out this experience with a sense of gratitude and celebration. read more

Highly Recommend OSH Construction The OSH Team provided my family with a resort type master bathroom that will stand the test of time for decades to come.  Sergio and his team transformed a 1970s décor into a modern marvel.  This team was professional, respectful, and talented.  They held to their schedule from the time they showed up in the mornings to their daily clean up.  What truly impressed me, was that the project stayed on schedule right up until its end. Communication is crucial for me.  The OSH team excelled in this area.  I received updates through personal visits, phone calls, or simple texts.  Any questions I had were answered promptly, which showcased the team's commitment to constant communication. We converted an awkward 10'x11' bland bathroom containing a simple shower stall and a large vanity into a open 3 spaces bathroom.  We now have a beautifully designed walk-in handicapped shower, a separate spacious toilet room and an upgraded vanity space.  All using a combination of high-end tile, fixtures, mixture of pocket and barn doors and a splash of paint to surround us with upgraded comfort and convenience. No job is too small or too large for the OSH team to handle.  I don't remember them ever refusing any of the design ideas we suggested.  We began with an interview with Sergio, and we hit the ground running on day one. As stated earlier, I highly recommend OSH for your next project.  These home projects are very personal, and the OSH team understands this, treating you and your home with the utmost respect.  When the time comes, I will certainly move forward to my next project with OSH by my side. read more

This was our second project with Sergio and Osh Construction, and we truly could not be happier. We feel incredibly lucky to have had Sergio and his team by our side as we navigated the various HOA and city requirements. From start to finish, they were professional, communicative, and reliable. We are so grateful to have them by our side throughout the entire process. This project actually began b/c Sergio and his team helped us discover leaks and water damage in our exterior wall during a previous project. What started as a straightforward rebuild of that wall eventually evolved into a much more extensive project due to evolving requirements from our city and HOA. Through all the changes and unexpected curveballs, Sergio remained patient, understanding, and incredibly helpful. He always explained our options clearly, gave us honest assessments of what to expect, and provided thoughtful recommendations. He never pressured us and always gave us space to make decisions. When things came up, he always patiently worked with us to adjust plans and schedules. Sergio was highly responsive and proactive throughout the entire process. His estimates were clear, detailed, and fair, and he made the effort to ensure our project always moved forward. When we began the actual construction, the team exceeded all expectations. On the very first day, they accomplished far more than scheduled. We had initially worried about living with an exposed wall, but thanks to their hard work and planning, the walls were closed up and windows installed right away so nothing was left open. The Osh crew consistently showed up early (typically between 7:30 and 8:30 AM) and was always courteous and respectful. Even on inspection days, someone from the team would arrive early to ensure everything was ready and wait for the city inspector because the inspection timeframes weren't posted until that morning. The crew often went above and beyond our original scope of work, taking steps to add value our home, help prevent future issues, and deliver the best outcome. The quality of their work is incredible. It's clear they take pride in what they do, and we trust them completely not just to do the job, but to do it right. Most of the work was finished ahead of schedule, and our final inspection passed on time. We're so grateful for all the effort, flexibility, and care Sergio and his team put into our project. If you're planning a project that doesn't quite fall into a neat box, and need specific work done, here are the details of our project. Sergio and his team did a phenomenal job with the following: demolition, insulation, exterior wall waterproofing, window installation (both retrofit and new construction), flashing, stucco, siding (cement and wood), and painting. all with excellent results. We absolutely plan to work with Sergio again on future projects. Thank you to the entire Osh Construction team for your outstanding work and dedication! read more

We are currently halfway through our home improvement project with Sergio, and I wanted to leave a review of the process so far and the work we've seen done because we're very pleased with how it is going. If you're looking for a contractor, I would strongly recommend reaching out to OSH construction and getting a quote from them. Getting quotes from general contractors and tradespeople shows you the wide variety of ways people do business. Some never called back or ghosted at various stages (didn't show up, never sent a quote, didn't do followup). And for the ones who did show up it really ran the gamut of helpful individuals to some that were less helpful. We went with Sergio and OSH Construction because he was Professional, had good communication, showed competence, had a good quote. As we have started the work he has only impressed us more. - Sergio had good communication. He was punctual and showed up when he said he would. He was respectful of our time. - During our quote process he provided useful information and asked helpful questions The Quote was - Competitive in price. It's hard to compare contractor to contractor because they will bill each line differently. On a line by line basis Sergio seemed higher in price, but overall his quote was competitive probably cause he wasn't hiding an extra line item for "Removal" or "Finishing" or breaking out the projects like others had. - Detailed enough : we got some quotes for roofs that were one line in a text, to 12 pages of detailed steps of work. Both are hard to use, Sergio's was about a page for the roof with a clear list of work being done and not being done. - Every work project on Sergio's quote like that. He said he wants it to be clear for each job what we are paying for. This helped out immensely during the quoting process as he updated the quote as we agreed upon changes. During the work so far - Sergio has remained an excellent and timely communicator. - We have a clear idea of schedule and what the teams are working on now and what they are working on next - In addition, we know what surprises they are finding along the way. Sergio and his team have identified more issues than we expected. Some are minor and his team is reporting and in some cases, just fixing them if they're small which we're grateful for. - Sergio's team is on time, and has been respectful of the place - They have cleaned up after each day of work and put things away. - I am currently in the house while they do some of the work and I appreciate how respectful and professional his crew has been. read more

Now that our full remodel is complete and we are living in the home, we felt it necessary to share how much we love the outcome. Sergio and his team simply exceeded our expectations.

We couldn't be happier and I would recommend Sergio highly!! read more

Choosing OSH was hands-down the best decision we made for our major home renovation. We've been through renovations before, and they're rarely easy--but Sergio and his team made the whole process feel surprisingly manageable, even enjoyable at times. Over the past decade, we've worked with several general contractors. Without a doubt, Sergio has been the best we've encountered. From the very beginning, he took the time to really listen to what we wanted--not just nod and move on, but ask thoughtful questions and offer helpful ideas. Throughout the project, he stayed flexible and solution-oriented, especially when the inevitable hiccups popped up. What really made a difference for us was the communication. We always knew what was happening, what was coming next, and where things stood. Sergio checked in regularly and made sure we felt comfortable with every decision. There were no surprises--and that's something we've never experienced in a renovation before. Even better? The project finished on time. That alone felt like a miracle. We could tell from day one that Sergio was organized and on top of everything, and he really delivered on that promise. And the quality? Top-notch. Sergio and his in-house team clearly take pride in their work. They don't cut corners, and it shows in the final result. His crew was professional, respectful, and a pleasure to have around--they treated our home with care and attention, which we really appreciated. Now that we're living in the finished space, we're even more grateful. We absolutely love how everything turned out--it's beautiful, functional, and truly feels like home. Every day we spend in this house reminds us how lucky we were to have found the right contractor. We're genuinely thankful to have worked with OSH. If you're looking for someone who's not just skilled and professional, but also kind, communicative, and truly invested in doing great work--Sergio is your guy read more

The absolute highest recommendations for Sergio (the owner) and his exceptional team at OSH Construction. Their honesty, professionalism, work ethic, attention to detail, and commitment to quality set them apart. They consistently go above and beyond, making what could have been a stressful remodel a smooth and positive experience. They are genuinely interested in their clients wellbeing, Interview and Estimate Phase: From the very beginning, Sergio stood out with his meticulous attention to detail, honesty, and transparency. During our initial walkthrough, he not only surveyed the project thoroughly but also identified potential issues and explained them clearly, patiently answering my many questions. Unlike other contractors who focused on upselling, Sergio genuinely listened to what we wanted and offered thoughtful, practical recommendations. He allowed us to visit some of his other job sites. His estimate and scope of work were clear, detailed, and fair, and he worked closely with us to ensure we felt completely comfortable with the plan. Once we confirmed, he provided a detailed schedule outlining the work process and payment milestones. The care and clarity Sergio brought to this phase gave us immense confidence moving forward. Remodeling Phase: OSH Construction's work ethic and commitment to quality are truly next level. Every day, Sergio provided updates on what had been accomplished, what was planned for the next day, and addressed any concerns we had with quick and clear communication. His crew arrived punctually (usually around 7:30-8:30) and treated our home with incredible respect. Because it was a partial remodel and we were still living in the house, they carefully protected our spaces, laying down canvas and plastic to keep the area clean and dust-free. At the end of each day, they cleaned up so thoroughly that it hardly felt like construction was happening at all. Despite his busy schedule, Sergio made it a priority to visit our project multiple times a week, walking through progress with me personally and ensuring everything stayed on track. Honesty and Integrity: Partway through the project, we realized that Sergio had underbid on one of the line items--something we were able to confirm by comparing with other estimates we'd received. His response speaks volumes about his character and integrity. Although I offered to pay the difference because I was so impressed with the quality of their work, Sergio insisted, "not a penny." Sergio's honesty carried through to the end of the project. While we didn't follow the schedule perfectly, he honored the original payment timeline without hesitation. Expertise and Problem-Solving: Sergio's team is exceptionally skilled and hardworking. When unforeseen issues arose--such as mold and termite damage--they were immediately communicated to us. Sergio assessed the situation in person and provided thoughtful recommendations. He walked us through our options and gave us space to make decisions without ever rushing or pressuring us. A huge shoutout to Imanol, Estachio, and the rest of the crew (apologies if I misspelled names!) for their kindness, patience, and expertise. Living in the house during the remodel was challenging, but they went out of their way to be accommodating, helpful, and considerate every step of the way. Special recognition goes to Susano, the tile master, whose 20+ years of expertise shine in the incredible tiling work. Our tiles are flawless and a true testament to his craftsmanship. Going Above and Beyond: Sergio and his team consistently exceeded expectations. Whether it was fixing hidden issues that were discovered along the way, going outside the original scope of the project to make sure everything looked perfect, or maintaining exceptional cleanliness throughout, they went the extra mile to take care of us and our home. In Summary: If you're looking for a contractor who is honest, thoughtful, highly skilled, and committed to delivering the absolute best, look no further than Sergio and OSH Construction. The experience was seamless, the quality of work unmatched, and the level of care they put into their work and customer relationships is rare to find. Thank you, Sergio, and the entire OSH Construction team. You've truly earned our highest praise and gratitude! Here are some pictures of the work (not the full scope). read more

I contacted Sergio when I was in escrow, and he was kind enough to go over the inspection report with me, and said he didn't see anything major. Fast forward, we were trying to do some cosmetic upgrades. Sergio came out and walked through our home with us. He was always very professional, helpful and responsive. Ultimately we decided to forgo cosmetic upgrades and just focus on maintenance. Overall, if you are thinking of doing some renovations, I wouldn't hesitate reaching out to Sergio! read more

Construction at its core is a stressful endeavor for most layman. However, Sergio relieved me of the roller coaster worries that I expected when starting my project! His calm and professional demeanor are an outstanding asset to any homeowner, no matter the size of the job.

From, Todd and Andi read more

I would easily recommend Sergio and OSH Construction to anyone. We were having our kitchen extended and remodeled and both bathrooms completely redone. As we were looking for contractors we came across OSH and all of the 5 star reviews and definitely put them on our short list. After speaking with a few contractors, we knew we could trust Sergio and decided to go with him. Since the time we first consulted with him up through where we are now in the middle of the project, we are very happy we chose him. We've heard all of the stories from friends and strangers about their bad experiences with contractors, but we can confidently say Sergio has been a pleasure to work with. He is honest, fair, and does what he says he will do. Everything he told us up front about the timeline has been on time or ahead of schedule. He takes care of all of the permits and inspections with the city, and he has multiple teams to be able to take care of the different tasks (as well as juggling projects with multiple clients). He gives a wealth of knowledge and experience to give recommendations on what would look good in your home, but ultimately wants to give you what you want and make sure you're happy. I'm very particular about how things are functionally, and my wife is very particular about how things look, and Sergio has done a great job of working with us to make sure we're both happy. I plan to update this review after the project is finished, but I didn't want to wait until then to leave a positive review. read more

So we started our the process interviewing 7 different vendors for a whole house renovation. We set a whole day and had them come back to back to place bids on the work. Part of the process was so they could get an idea of the scope of work to be done but also for us to assess them from a professional level and how they interact with their clients. After that entire process I remember liking most of the vendors but my wife made the comment that I seemed to be talking up Sergio more than the others. Fast forward, we end up hiring OSH construction for the job. A few things that stood out right off the bat from our first interaction. 1. Professionalism - Sergio and his team were prompt, quick and responsive. He provided a detailed invoice that laid out all the work that was discussed to be done on the home. Not once did we ever feel like we were being upsold, and in several instances they ended up doing more work to make sure they weren't cutting corners even if it meant them eating the cost. The workmanship is more than we could have asked for. 2. Ease of work - Sergio and his team's goal was clear off the bat, they were aiming to please their customer. There were so many instances where I thought a change order would be needed or where I'm sure other vendors would have nickel and dimed us for repairs, but Sergio just did them because he wanted the job to be done right. This is what stood out to my wife and I the most and why we've been raving about him to our friends and family. 3. Price - Sergio's pricing was very competitive, while he wasn't the cheapest he was highly competitive. We had many quotes, some much much higher than Sergio's and some lower. Sergio's price was fair and with the amount of work they put in, I would say he was more competitive than our lower quotes 4. Trust - This whole process was fantastic from beginning to near end. I can't express how much trust we've put in Sergio and rightfully so. He's delivered on all fronts so far! We look forward to working with him and his team again for future renovations that we have planned. If you need a general contractor DO NOT SLEEP on OSH Construction! read more

We also had a microwave replaced and just this morning a gfi outlet needed replacing. Israel arrived right on time and even helped us with our Nest system! We will call again when we need a project handled! read more

I called four contractors for a estimates on a new fully permitted bathroom on the second floor bonus room above the garage. Sergio responded in a timely manner. We setup an appointment for him to look at the space. The space is very small. His quote was very reasonable and one of the best out of the four contractors. Sergio and his crews arrives early as scheduled on Monday and proceeded to demo. They updated me at the end of the day everything they work on that day. Which was very helpful on the status of the construction. They work through Saturday and they even work on one Sunday to finish the job. The whole crew were a pleasure to work with at all time. I am so glad I contacted Sergio for this job. He is a pleasure to work. He explain to me what and why needed to be done. He also recommended to me where to purchase the bathroom tiles, vanity & faucet. He even installed my new garbage disposal at no cost. I am very happy with the new bathroom, it look fantastic. The workman craft was excellent and beyond my expectation. I definitely will work with Sergio and his teams again in the future. I would totally recommend working with this company again. read more

Sergio and his team are top notch. We started our house remodeling back in Oct 2024 and what we had thought would be a quick renno ended up being a huge undertaking. Sergio came to the rescue literally that same day to help us remove beams to create a more open space in the kitchen and living area. His team was super respectful, clean and timely. Sergio also takes his time to educate and really cares about doing the right thing. He helped us with our kitchen, dry wall and other parts of the house. If you're on the fence of who to choose when it comes to a licensed contractor, you will not be let down choosing Sergio and his team. He's overall just a great person and helps out immensely during times of getting through a stressful project! Thank you for everything! read more

First and foremost .... My husband left a review and it was buried and not recommended to read .... So I will include a picture of the review because his reason for posting was to be heard. With that said ...... Sergio (the owner) has done several jobs for us. He was recommended 3 years ago to instal in above ground pool, and the deck to go around it in an older beat up home we bought in Orange. Now .... Our first goal was to simply get water to play in.... Deck was aesthetically important but not necessary. We were so pleased with price and professionalism.... We stalled backyard deck and proceeded to rip out kitchen And begin remodel. Construction isn't fun. However.... Every day I came home from Work to a new level of HOLY MOLY I love my kitchen !!! Please understand my kitchen and home is small .... But MIGHTY. During.... Floor instal in pantry hallway .... There was a worry with bathroom Floor. So Sergio recommended to take it up.... The mold in shower, shower walls, and floor was shocking. This began ... bathroom remodel..... which only lead to my darling beautiful bathroom. Aside from just a all around great person with a great price .... I must tell you , letting men you don't know into your home To work can be challenging. His crew was always professional and aware of where I was just as I was aware of where they were . Once I dropped a bag of small bottles that rolled all over my front yard, easy 30 bottles. His crew stopped and picked up my bottles for me. We loved our kitchen so much .... We hired him yet again (even after pricing out again) to add an addition on to our home . We have recently completed that project and can't be more pleased !! That project initialed taking Off the back end of my current garage . New slab. New build off garage . And granny pad for mother in law. Picts and videos wi be included. This current construction relationship is still underway and not done . More projects to come. One more bathroom needs to be handled .... And don't forget a deck still needs to go in . I'm sure much much more . Please understand ..... construction brings out lots of emotions .... And I felt them All. Sergio and his crew help deflate all the crazy you feel going through it . It helps to not dislike or dare I say hate your contractor and his team. I promise Sergio says what he means and means what he says . He was honest , fair , professional ..... and mostly GOOD AT WHAT HE DOES ! I will gladly recommend this person and will continue to Yelp if this gets buried !! Check out my Picts !! Damn .... Seems I can't post a video ... that was a full video of granny pad. read more

OSH Construction is THE BEST!!! We are extremely happy with our "new" home! Our kitchen, living and family room remodel took about 80 days to complete. We consulted with three other contractors, but OSH was the only one to give us a complete and fair quote. During our first encounter with Sergio, the contractor, his organization and professionalism really jumped out at us. What solidified our decision to choose OSH for the job was when Sergio invited us to see a couple of their other reno sites, which were both bigger than our project. We were very impressed with their work, as well as the number of workers at the job site. One of our biggest concerns with starting our reno was that we needed to be home throughout the project. The guys did a great job in sealing off the work areas and cleaning up at the end of the day. The guys were very respectful, hardworking and organized. They would arrive at 730am and be cleaned up by 330pm, six days a week from Monday thru Saturday. They were always upbeat, and from what we can tell, more than happy to do their jobs. A sign of a good working environment and leadership. About ninety percent of the time there was four of five workers. In our neighborhood, multiple construction sites can be seen throughout the year, but we've never seen one with workers present every day. In addition, we've always heard how hard it was to pass inspections with OC Public Works, but we didn't experience any of that, not one. Throughout the process, Sergio made suggestions that we either didn't consider or thought impossible to do, most notably an island waterfall effect. We were skeptical it could be done, considering our island was already the biggest quartz slab that we could find and no two slabs have similar veining. He guaranteed we would be happy with the continuation of the pattern, but that if we weren't he would remove the extra quartz at no additional charge. AND that he would eat the cost of the materials. Needless to say, we were blown away with the end result and it's the perfect finishing touch to our beautiful kitchen. We tried to be model clients but admit that we may have made things complicated sometimes with quite a few order additions. For instance, mid construction we decided we wanted a custom hood, paint other areas of the house, change and add crown molding, customize certain parts of a prefabricated cabinet, etc. Sergio was great, always said "no problem, you're going to like it." And we love it all. It's absolutely worth repeating that we couldn't be happier with the final results. OSH gave us a kitchen, living and family rooms beyond our imagination. We love the openness and brightness that we now get from natural light. We are so appreciative and grateful for the wonderful group of people at OSH Construction. We would absolutely and highly recommend OSH to anyone who's looking for a contractor. We have, in fact, recommended them to a few people in need of a good contractor. Such excellent workers, experts at what they do, and work hard to get the job done right. read more

I have used OSH Construction for any of my home improvements since 2018. Sergio and his team are professional, honest and hardworking. They always finish the projects on time. Sergio does great, quality work and is very particular to all minor or big details which is great. And I love how clean and careful Sergio and his team are when working. They don't leave a mess behind nor during construction. We found Sergio through a word of mouth referral when we were looking for someone to help install an above-ground pool with a deck in 2018. They did an excellent job, going above and beyond my expectation. I continue to this day to use OSH Construction services. He's done work -- to name a few -- such as installing double-pane windows, installed split AC units, flooring, paint, and recently, kitchen remodel. read more

Sergio and his crew were amazing! We used them for a complete master bathroom remodel and they were absolutely great from the first estimate until the last finishing touches. Sergio is honest and straight forward and is always looking to make the customer happy. He encourages multiple estimates and we had no surprises. His communication was great with daily group texts with my wife and myself letting us know what was done each day and what would be happening the next day. We also had a calendar at the beginning of the project that showed what would be done each day. Overall their communication and organization were first rate and we couldn't be happier with the result. read more

After getting several estimates for a kitchen remodel, we were referred to OSH by a friend. Sergio came over the same day we called him for an estimate. He spent time with us reviewing the estimates other companies provided. He helped us research the companies and he provided us an estimate of his own. We met with him several more times before deciding to go with him. Sergio was very helpful, honest, and considerate of our questions during the estimate process. We started the work a few weeks later and Sergio was there with us every day making sure we had everything we need. There were quite a few issues that were uncovered during the process due to our house being older. Sergio and his guys worked through the issues and did the extra work to make our dream kitchen come true without increasing the price. OSH teams were professional and courteous during the entire process. They cleaned up after themselves every day and kept the work area in the best conditional possible. The crew worked hard every day from start to finish. They did not take very many breaks and they even worked on the weekends. Sergio was there at the end of every day to make sure things were going better than expected and that we were happy with the work. As the job got started we had many changes to what we wanted. We started off wanting a kitchen upgrade and we finished with a complete house remodel. We removed interior walls, closed windows and an exterior door, replaced an exterior door with a sliding glass door, added a shower to a half bathroom, added a bar top peninsula cooktop, installed a wall oven, replaced floors in the living room, dining room, bathroom, hallways and painted the interior of each of those rooms. With all the extra work included, the OSH crew still finished the job in 2 weeks and 5 days...2 days earlier than estimated. The work was amazing, the time they did it in was beyond belief, and the care and professionalism was top of the line. I've heard nightmare stories about construction companies and I was kind of expecting the worse. With OSH doing the work we had no such bad experience. I can't wait to have them do more work for me and look forward to hiring them again soon. Before and after photos included in this review...enjoy!j read more
