    We were so happy with our new windows. We have already noticed a reduction in outside noise and a savings to our energy bill by not having to run our AC as much. Our sales representative, Cody, went above and beyond by working on his birthday and ensuring that we got exactly what we wanted. The window installing crew led by Boris was very courteous and professional. Boris did a walkthrough with me with every window that they installed. I am impressed with Alpha EnviroTech and will look to them the next time we have a major project. Great work!

    I LOVE my new windows! A few of my old windows were starting to leak in heavy rain, so I decided to replace them with Alpha. Their sales person, David, came by to show me their product. He was great - explained everything and demonstrated how the windows they install block sunlight to significantly reduce heat in your home. I live in Southern CA so this is huge! I've already noticed a difference in indoor temperature on sunny days, it's much more comfortable during late afternoons when the sun used to heat up my family room and make it stuffy. I expect my electricity bill will go down this summer as a result as well. The double pain windows also reduce noise, and they are a breeze to open inward to clean. Installation was super fast! I had every window in my house replaced (19 total) and the team - led by David (a different David) and Marco - did it in 2.5 days. And they did a great job!! It was noisy, no doubt, but the team was friendly, courteous, and very respectful of my home & property. They cleaned up at the end of each day and made sure any trash was hauled away. My windows look so good! I was hesitant to do this because it's a big project and expense, but it was so worth it! The windows Alpha uses are specifically designed for CA weather, are reasonably priced, measured to fit your windows, and as mentioned above reduce the amount of sunlight blasting into your home in addition to reducing noise. I love them!! Thank you, Alpha - you did an amazing job!!

    I just had my house painted in Sacramento, CA. I think the business is expanding. I love my paint job. They did an amazing job. They also repaired stucco and dry rot areas of my trim. The guys were very easy to work with. Now in the beginning when they were trying to sell me the paint job and going over all the qualities this paint has I thought they were just putting on a show but since I've had my house painted my air conditioner gets the house sooooo cold! This paint is supposed to help insulate, be a moister blocker and fire repellent. The difference from before the house was painted is out of this world. My air conditioner would have to run all day to get this cold, now it's freezing in an hour. Plus it looks so nice . I've fallen back in love with my home. Next project: fix my yard up!

    Fantastic and Reliable. They completely the job timely and were extremely professional, punctual and easy to work with. The quality of their work is exceptional. I feel like I have a whole new house.

    SoCal Roofing did an amazing job on our roof, which we had done in October. We had six different…read morecompanies come out to bid, and while they weren't the lowest bidder, they came in pretty darn close to the lowest bid. Besides price, our other priority was a company that did not use subcontractors, and SoCal Roofing only uses their own employees, so we felt confident moving forward with them after checking out some of the previous homes they'd worked on. From quote to install, the project went very smoothly. They were quick to respond to any questions we had, and the full roof replacement was done in about three days. Timing couldn't have been better, since we got several days of rain a few days after the install, so it was the perfect time to "test" the roof to make sure there weren't any leaks. We were solid. Among all the businesses we've worked with for other upgrades to our home, we can honestly say that SoCal Roofing is one of the only ones where we have felt 100% confident in the work that they did. They are very thorough with their work and you can tell they truly take pride in it. We would happily recommend them to family and friends.

Carlos came out and provided 2 different quotes, one for full replacement and another one for replacing only a portion to include upgrading all the vents. I wasn't expecting that but after consideration, I thought that was the best option. We scheduled the repair and they were prompt, professional, and clean. His team came out on time and worked like a machine to complete in one day. They cleaned up after they were done and then the foreman came out same day to inspect and perform quality control. Aside from saving me thousands on our options, I was very impressed with SoCal from start to finish. I would highly recommend their services.

The roof looks great and I'm not worried about rain now. The quote was on the higher side but because of their professionalism I'm glad I went with them. I highly suggest them if you want a real good job and won't just do the minimum. Thank you Terrazas Roofing!

Did my research and got several quotes from various companies. The owner (Francisco) gave a very reasonable quote for the work. My flat roof was about 1200 sq ft. They replaced the entire roof in several days, replaced much of the fascia wood and primed it all (haven't decided what color paint yet). I felt that this company was honest with pricing and reasonable. So many people are taking advantage of insurance companies demanding major repairs that may or may not be needed and there are a lot of roofing companies that are overcharging for work. They were very transparent about costs, did the work quickly and professionally, cleaned up, and were kind to my family. Very thankful for their work!

During the job itself they…read moreseemed like nice guys, talk you up about customer service etc. But as soon as the job was done I noticed that the clay tiles I had was not aligned right. Some was so bad that you could literally see exposed underlayment. I was only able to catch this due to a bathroom window I have that just happen to overlook it. If I got the work done on a different part of the roof, probably would never have noticed. And would never be able to call them to address it, so keep that in mind. What's worse is that since the roof work there was no major rain for 16 month, which is outside of the 12 month warranty. So I guess if you never put their roof to the test against mother nature then I guess it's perfect service. But the first time it's suppose to do its job it fails to do so. At this point I'm not sure what they did mess up my tiles and take my money for the privilege. I would literally be in a better position had I not paid them to do "work" on my roof. I tried contacting them several times and met with the cold shoulder. I'm probably just going to eat my losses here but if you're considering them, just be warned. Or make sure it rains in the warranty period!

When Arturo came out to inspect the roof, he provided a verbal quote, but no written estimate was ever sent. Since my husband and I were in the process of making decisions based on contractor bids, I later reached out and specifically asked if a written quote could be provided. After waiting without receiving anything, I followed up with Arturo by text and was told that he would send the quote later that day. Four days passed, and I still did not receive the written estimate or any update. I sent another follow-up message and received no response at all. The only positive part of my experience was communicating with their staff, Abigail. The person responding to my texts, who I believe was Abigail, was responsive and helpful whenever I reached out to the company's main number. Unfortunately, despite her responsiveness, I still had difficulty getting the information I needed from the technician assigned to my project. I understand that delays can happen, but timely communication and following through on commitments are important. Based on my experience, I was disappointed by the lack of responsiveness and would encourage the company to improve communication between their technicians and potential customers.

Top Roofing gave us exactly the kind of experience we hoped to have when taking on a major home project. Our project manager Ever Diaz was fantastic, and he was upfront and honest about something every homeowner should know going in: once they open up the roof, there can be damage that wasn't visible during the initial assessment. We suspected might need a full replacement, and yes, we did but Ever showed us thorough evidence and we were prepared for it. Ever's honesty about that possibility from the start helped us trust him immediately. His crew was professional, hard-working, and kept everything clean throughout the job. That's no small thing when you're talking about a full roof replacement. When the job was complete, you'd barely know they were there, except for the beautiful new roof they left behind. What really set Top Roofing apart was the support we got beyond the job itself. Office manager Amy G. went above and beyond. She handled all the permit coordination seamlessly, and weeks later when we received a random letter from the County Assessor's Office, she took the time to help me complete it. That level of care and follow-through is rare, and we genuinely appreciated it. They do quality work, keep things clean, and actually take care of you through the whole process. I highly recommend them!

He also has a strong understanding of local roofing requirements, including the specific tile types and sizes commonly used in the area. Furthermore, their price is quite competitive. Throughout the project, Bryan was highly responsive and addressed every concern promptly. His crew demonstrated exceptional professionalism, and it was clear they took pride in delivering quality workmanship rather than simply finishing the job as quickly as possible. They even spent additional time replacing rotten wood and repairing a damaged rafter to ensure the roof was done correctly. Overall, I'm very satisfied with the experience and would confidently recommend ASR to anyone looking for a reliable roofing contractor.

Throughout the whole process, I was impressed by Bryan's Professionalism,…read moreresponsiveness, and technical knowledge of details as he had 10+ years of roofing experience and now handles sales for the family business, which gave me a lot of confidence during the project. Importantly, there is no subcontracting unlike some other roofing companies which stated their use in fine print. The entire crew worked seamlessly work together in unison to finish my whole reroofing in 3 days. I was initially skeptical since others stated 5+ days, but I could see how organized and efficient the team was. Since roofing is expensive and stressful, I made sure to get four other competitive quotes from other roofers. The price from ASR came out the best with the same specs, but I would still have went with ASR even if they were more expensive, just because of the trust I had in Bryan. Throughout, I got to meet Bryan's father, Frank who has 30 years of roofing experience and was accommodating to my needs such as when I requested protection of my garden during tear-off. I also met Bryans brother Steven during the shingle installation, which reinforced the sense that this was a family business that genuinely cares about the quality of their work. Finally, after the installation was finished, the team still cared very much about passing inspection for permitting and to ensure their reputation is upheld. Even after payment was completed, they continued providing follow-up support when needed, which gave me additional assurances in their commitment to quality. I highly recommend All Service Roofing (ASR).

I was provided with a non English speaking crew, which made it hard to communicate important details. Because of this, I was never informed that my previously installed EV charger would create a solar permit issue. That oversight ended up costing me an additional $2,000. For a company charging at the higher end, I expected clear communication and a thorough review of existing electrical work. Instead, I was left paying for issues that should have been identified upfront. My advice to future customers: - Make sure they thoroughly review all prior electrical work done in your home. - Ask specifically about permit implications before signing. - Get clear confirmation on who will be onsite and whether they can communicate effectively with you. - Do not assume they will proactively flag electrical conflicts, you may be asked to pay for corrections later. The company is on the expensive side, and I accepted that cost in exchange for what I believed would be a smooth, well-communicated experience. Unfortunately, the communication breakdown and unexpected added costs did not justify the premium pricing. Proceed carefully and ask very detailed questions before committing.
