We had water damage and the insurance company hired Karson to rebuild our kitchen. They talk a good talk, yet their workmanship is inferior. They ruined our beautiful custom kitchen cabinets and to this day we are still finding issues with their poor workmanship. Our laminate floor has a large gap between 2 planks that I have to pick crumbs out of with a toothpick. Our custom Omega cabinets were not properly sanded and prepped and the stain they applied is coming off all over. (They did give me a paint pen to touch up those spots although it just rubs right off). They torqued the door of our Bosch dishwasher when putting it back and place and they wouldn't accept responsibility for the fact it started leaking after that. I could go on with more issues. Best advice is call someone else! read more

I just don't understand why it's not 5 stars across the board with every review. These gentlemen's working at the site are nothing short of amazing at their craft. The work was Flawless!!! And I'm a stickler for details. I had a water leak that created a lot of damage in the kitchen walls as well as underneath the floors. The leak literally traveled through the walls From the kitchen to the other side of the house. I know... cringe. And as a homeowner, I'm freaking out and panicking. Well... Dustin and his amazing Team worked their magic and poof. Need I say more. Please See pictures below read more

Just remodeled the shower build Karson did 3 yrs ago. We hired Karson to fix a shower leak through an insurance claim. The shower they installed was so poorly constructed that within a year we began getting tiny black worm looking bugs in the shower corners and drain! The shower door was installed upside down, backwards and bent! When we finally demoed their work, we found the subfloor and wall rotten under the tile! Mortifying! Took them 6+ wks to complete this job and most the time workers did not show up. Pretty sure they just pick up workers hanging outside of Home Depot. Awful! read more

Karson construction did such a great job on our main bathroom during this trying time. They installed a new bathtub, toilet, vanity, flooring and tile work. Love, love, love our new and amazing bathroom. The employees were on time, courteous and professional. They ensured to cover everything in plastic as needed and ensured our wood flooring was protected while going in and out during the remodel. I would highly recommend Karson construction for any job, big or small. This is our 2nd time having them take care of our home needs. read more

Carlos is friendly and a bit of a perfectionist. He sets high standards for his crew and himself and always makes sure that the customer comes first. I wish all of the workers I hired were like this crew. Would I hire them again? In a heartbeat. read more

I honestly wish no stars was an option. We had our initial walk through with Dustin back in June. Cut to six weeks later, after having to chase them down for an estimate with repeated promises of "you'll have it soon", I finally receive this ridiculous excuse for an estimate. Over 10,000 for a 5'x8' bathroom?!? We planned to provide all materials, it was purely for labor and they wanted 10,000. The estimate had no itemization of cost just a list of what they planned to do and an arbitrary number thrown on there. I immediately canceled our start date (which was to be two month after the initial meeting because they are "so busy") and will be finding a new contractor. This company is appalling in their lack of professionalize and I strongly advise against considering them for any projects in your home. read more

We used Karson construction to fix/remodel our kitchen after a water leak. The job took a while to start due to them having a busy schedule, but once it did, they diligently came daily to "knock it out" in one go vs having crews come here and there. Dustin and his team are very professional, punctual, and performed good quality work. I am very pleased with the experience and end result. read more

Karson Construction - Kitchen. Existing cabinets that were refinished. New counter top and backsplash: - General Contractors Near Me - Chino Hills, California

I called Karson as a referral to mount a kitchen sink. I had my plumber out to install the sink but it required a couple of small cuts in my countertop to make space for the mounting brackets and he didn't feel comfortable making the cuts. So I left Karson a message on Thursday afternoon. They responded on Friday AM and scheduled an estimator to come out Monday. So far, so good. The estimator provided a written estimate for $500 to make the cuts to the countertop, mount the sink, and seal it with white silicone. They did the work and I scheduled my plumber to come back the next day because I was told the silicone needed a bit of time to set. I saw some bubbling in five different sections around the sink but figured it would settle as mentioned by the technicians. My plumber arrives the next day and come to find out, instead of cutting the countertop and mounting the sink, Karson cut the mounting nodules off the sink and glued it in. They did not use the mounting brackets and this thing is now held in place with glue. Karson never advised me that they could not perform the services as originally quoted and never informed me they were doing anything other than what was agreed upon. Even the final invoice they sent after the work was completed and my payment cleared, listed the same exact estimate (including cutting the countertop). I asked my plumber to try to fix the silicone but he was unable to because it is was not silicone, it's some type of glue. Trying to even it out with silicone would look even worse. It never settled and still has bubbles. The pictures attached were taken today, three days after their work was completed, so I doubt anything is going to settle further. I also now have two black marks on the back of the sink that will not come off. It's probably scuff marks from the grinder they used to cut off the mounting nodules on the sink. PROS: -The customer service/people who handle invoicing were nice -Responsive and were able to get someone out quickly -Everything was clean when they left -Technicians/estimator wore masks CONS: -Did not do work as agreed upon and did not inform me ahead of time (or after the fact) that they did work not specified on the estimate -Poor job applying silicone/glue(???) -Damaged sink -Only accepts check or money order Overall, 0/10 would recommend. read more

I don't typically leave reviews unless I'm blown away by a company's Customer Service. When someone leaves a negative review, and all other reviews are stellar, there has to have been something going on! It really isn't fair to hard working companies when a disgruntled customer who doesn't make good on their contract writes a BOGUS review. Karson Construction totally deserves your business. They worked with me on what I needed and were just amazing to work with. I'm a single Mom and the flooring in my bathroom actually felt like I was going to sink into "quicksand"! They fixed the situation and actually helped me to feel safe again in my home. read more

Completely disgusting... If I could give Karson Construction negative stars, I would. What started out to be a positive experience when Dustin (who by the way is friendly and knowledgeable), came to my home to assess the work, quickly turned in to a GIANT storm of garbage. First of all, the estimate for the work that was needed was ridiculously high, and included so many unnecessary items. My main concern though was that they failed to communicate with my insurance adjuster. It was not until I sent an email stating that maybe the job at my home did warrant a call back to either my self or my adjuster, did I receive a call back almost immediately from Marielena. I stated my concerns, and she had the "manager" Amy, call me back. The conversation with Amy was by far the WORST customer service that I have ever received in my life. You cannot tell a potential customer that the company is communicating with your adjuster when they clearly are not. Oh, my mistake, they left her a message AFTER I sent my email expressing my concerns. Thankfully, after all of the back and forth with Amy, I was able to cancel our contract , and trust me, I am not sad. There are better construction companies out there. No thank you Karson Construction. My expectations were not met, and your level of customer service leaves something to be desired. Except Dustin, he's great! read more

This is the first time we have used Karson construction and would definitely use them again. They were very professional did an excellent job, always on time, great communication. Fernando was in charge and he did a great job. Maureen Griffith Park read more

This was my first experience having to work with fixing a bathroom leak that destroyed my kitchen and Master bath. I am so thankful my first experience was with Karson, they have set a high bar of expectations. Ivon was an incredible asset, she was very knowledgeable and always answered the phone with a pleasant tone and sincerity. Fernando and Chewy and one more employee that I can't remember his name worked on my house. All three of them were absolutely the best. Always on time, considerate and great work ethic. Fernando was always providing up to date information and always did it with a smile and genuine attitude. I would highly recommend this crew and company! read more

Tim and his team did an exceptional job with our kitchen and bath. The project was quick and very streamlined. They are very professional and offered us their expert opinions regarding design and materials. They even beat the price compared to a non-licensed contractor who was giving us the run-around. Their team was very careful during the demo process and handled the materials with care. Tim and Jorge gave us daily updates and prepared us the upcoming day so we knew what to expect. Our kitchen and downstairs bath looks beautiful and has added storage. It fell nothing short of our expectations. I look forward to working with Karson Construction again and would recommend them to anyone who needs work done in their home. Thank you again for the incredible work, professionalism and punctuality! I included before and after pictures below. read more

Karson construction repaired my bathroom after my skylight leaked and flooded my bathroom. Carlos, Miguel, and Sergio did an outstanding job from start to finish. They were pride, polite, always on time and went above what we agreed on. They did not charge me for some extra electrical work I decided I wanted done at the last minute. My bathroom looks beautiful. I'd hire this company again and will in the future. Susan ...Riverside read more

Had a water heater leak with slight water damage. Karson came in and restored the drywall and paint perfectly. They also restored the water heater perfectly. I have a maintained garage (painted floors, recent paint) and they cared for it and cleaned up when they left. Very recommended. read more

It's not often I have to fire a contractor for sheer incompetence, but that's all I could do when after five months these criminals still hadn't completed a simple bathroom restoration. After needlessly tearing out tile and marble, they cashed their insurance check and promptly vanished, claiming they were unable to get marble samples for us to approve. Then they insisted there were no such things as octagonal tiles...which we eventually found. All these pirates are missing are eye patches and peg legs. If you ever file an insurance claim, be sure to avoid them. We ended up hiring replacements who were way faster and less expensive. Their six month never-ending ripoff will be completed in less than four weeks. read more

Had water damage in my garage from the heater. Dustin came out for a quote and work started right away. They worked with my insurance and the job was done in under two weeks. I didn't experience the negative issues the others are complaining about. Job was done quickly and right all during this crazy time. read more

They redid our cabinet and drawer wood surfaces in the kitchen in March 2018. It looked good for about a year. Then I started noticing that the finish was coming off in many areas. The first thing they told me was that, "I told you it would only last a year." And, "It was not a fault of our product. It is from use." We use our cupboards and drawers in the kitchen as they should be used and are not rough with them. The previous cupboard finishing we had lasted over fifteen years before it started fading. I would not recommend a company that refinishes cupboards that barely last a year. It is expensive... and now our cupboards look worse than they did before we got them redone. Their customer service when they came to the house to look at the cupboards was defensive and unhelpful. read more

Actual rating.... -10!!!!!! Worst company ever!!! Dustin comes over to give an initial quote & you will NEVER see him again!!!! They make empty promises & their work is sloppy!!! They will vacuum up cement with your $400 dyson vacuum cleaner & pour the rest of the cement in your flower bed!!! They don't cover any of the furniture and don't clean up the mess when they leave!! Expect to spend at least 24 hours trying to clean up the mess they left behind!!! Their work was so bad that I've had ants in my bathroom since they left!! I finally had to caulk all the cracks they left myself just to keep the ants away!!!! And they will just get rid of/break your mirrors/closet doors without telling you & then expect you to pay for it - even tho it wasn't included in the original estimate!!! I would never recommend this company to anyone!!!! read more

We started the new year with a water leak. The company that did the dry down, recommended Karson Construction. Dustin Lawson gave us an honest analysis of the scope of work. He worked well with our insurance company and the work was completed within the timeframe promised. There were a few hiccups but Dustin and his team bent over backwards to make the corrections. The entire team worked efficiently and the house looks better than before they started. I would highly recommend this company. read more

I absolutely recommend Karson Construction. In the end of February my husband had the brilliant idea of hanging a new lighting fixture above our island in the kitchen, little did he know our overhead fire sprinkler system was really close to the area he just needed to make "a little bigger" for the fixture to fit. Guess what happened next? Yup, my brand new kitchen and house was now flooded. We've only been in our new house less than a year but because it was a problem we created our builders wouldn't cover it. So I reached out to Karson Construction because they were recommended by a friend in our neighborhood. I spoke with Aimee and they immediately had someone over to our house the next morning. My husband was so embarrassed to say the least. Dustin came in, did the evaluation and told us what would need to be done. From the time we met with him to the time they began working on our home was less than 2 weeks (mainly because we were waiting on our insurance to approve the estimate). They were professional, knowledgeable and completely upfront on the timeline it would take for completion. Then if it wasn't already bad enough, a freakin pandemic hits. We thought for sure our construction would be halted but nope, they took all the necessary precautions and finished up ahead of schedule. The work was done beautifully and our kitchen looks better than it did before the incident happened. I'm shocked to read some of these other reviews cause it definitely was not the service my family and I received. We are so thankful that this process was timely, efficient and that the staff was able to accommodate our needs even after a pandemic was announced. Thank you to Tim and Dustin for all of your help! read more

We recently purchased a renovated home we loved except the guest bathroom. It wasn't at all our taste so we hired Karson to redo the entire room to our liking and they did an excellent job at implementing our vision and even had a few ideas which we hadn't thought of but made the esthetics even better. The workers were professional, on time, and did a great job. Thank you Karson Construction. read more

Karson came out after we had some water damage to the kitchen. They were friendly, professional, and did an exceptional job. They had a good quote, and held to it. I'm extremely happy with them and would use them again for another job. read more

Terrible experience. Dustin, who provided the initial quote at walkthrough, was professional and great to work with, but the work completed was extremely shoddy, had to be redone multiple times, tiles were uneven with cracking grout, surfaces werent level, etc etc. read more

Worst company ever, had Insurance damage, karson gave me a estimate for the bare minimum, I signed the contract than they told me they are to busy and couldn't even tell me when they could begin. 2 months went by, I got tired of waiting so got a second estimate. The other company came in $5,000 less with all upgrades where karson was putting my house back to its original state. So I canceled with them now they want a 20% fee for doing absolutely nothing. I should of known better than to sign the contract but it just shows how greedy people are. read more

I had termite damage,and needed the outside of my house painted. They did a great job, the workers were very polite and professional.

Any other issues with my house i will only use KARSON CONSTRUCTION. read more

The work performed was Great! Highest regard for their work.

We had water damage in our family room wall/ceiling and garage ceiling. Karson was recommended by the mediation service because of their attention to detail and customer care. We were not disappointed. Dustin Larson gave us a detailed quote and his crew accomplished the work perfectly. Jesus, the crew chief, made certain the work was performed to his satisfaction which was a high standard. The outcome was better than we expected. It took a few weeks for them to get to us but it was worth the wait. I'm sure they are in high demand. read more

Great experience. Dustin, who provided the initial quote at walkthrough, was professional and great to work with, the work completed was shoddy, had to be redone multiple times, tiles were uneven with cracking grout, surfaces weren't level, etc etc. After it was redone I was over charged, which was fine by me because I enjoy long delays and shoddy work!!! read more

Karson's people, from Aimee in the front office, to project manager Dustin Lawson, and his talented specialists who did a total R&R on my bathroom, are this company's greatest strength. I felt supported throughout the 3-month long project, with all questions and concerns answered promptly. Because this remodel involved an insurance claim, there was a lot of paperwork back and forth--Karson never dropped the ball. The quality of work and attention to detail was excellent, esp vinyl floor install and shower rebuild/retile. I recommend them highly. read more

The ice maker in our refrigerator burst and we had a huge flood on the bottom floor. Karson took care of all the reconstruction, including floors, walls, paint, kitchen cabinets, etc. They did an excellent job. The workers were always on time, friendly, helpful and always cleaned up when they left for the day. Dustin was always available for questions we might have had. I would definitely recommend Karson Contruction. read more

When a water line burst under my refrigerator and damaged my kitchen cabinets and hardwood floors, I was prepared for a long and difficult restoration process. Luckily for me, my restoration company recommended Karson Construction. Dustin, the owner, is trustworthy, reliable and his people do good work. He came out the day of the loss to get a look at the work required even though he wasn't in the area - which I appreciated. He communicated clearly with me and worked quickly and effectively with my insurance company to get all of the necessary work approved. I ended up having to refloor the entire house and the kitchen cabinets had to be restored and restained. I stayed in a rental in my neighborhood while the work was completed and all the workers (floor and cabinet) were talented and responsible. Dustin understood my concerns about being out of the house for too long with 4 pets and a teenager and worked as best as he could to accomodate my schedule. He made sure the finish work was completed to my satisfaction. I highly recommend Karson Construction. read more
