    I am more than happy with my choice to go with Good Guy for my little home salon studio. They…read morelistened to what I wanted, double and triple checked on even the smallest details to make sure it was completed the way I wanted, and even made some helpful suggestions that I hadn't even thought of. They were on it. Since they have carpenters, mud and texture guys, electricians, plumbers, HVAC, you name it, They would send who needed to be here at what time to make the process as speedy as possible, showed up when they said they would and worked until the project was done! Everyone who was sent out was very friendly and respectful, also leaving my place clean when they left for the day. I would receive almost daily logs of who was here from what time to what time, reports of progress including photos and estimations of percentage of each piece that was left to do, and how close we were to the projected estimate. Everything turned out beautiful and works perfectly for what I wanted to use it for. I will definitely be calling them in the future with any and all construction needs. Thanks Good Guys!!

    I hired Mark for a medium-sized remodeling project (about 6 weeks) . He provided a low estimate…read morecompared to other bids. He then said that his workers were all covered by Worker's Comp, among other benefits, and that he paid a fair wage, and that he was the most ethical contractor in the industry, resulting in his workers' being highly productive and efficient leading to shorter project times. This sealed the deal for me. Furthermore, he claimed that the extra 30% or so that he was billing for his workers, was due of the worker's comp insurance, which only he provided to his workers (as opposed to the many unscrupulous other contractors that were around). As a property owner, you could be held liable for workers' injuries if the contractor did not carry worker's comp, and so, I agreed to Mark's deal. Within a few days, Mark had exceeded the estimate he had quoted, and was very difficult to get hold of. Furthermore, his workers would come and go at all times of the day (between 7:00 am and 8:00 pm) and I simply lost track of how many "cooks" were in the kitchen. As of last count, I noticed some 15+ names on the invoices, and some would appear for a couple of hours, and then disappear. But Mark would send me invoices claiming that his workers spent the entire day at the property - which was simply untrue. Mark would not be interested in even listening to me or investigating my grievances. Instead, he would brag that he did me a big favor by accepting my project, and that he typically only did multi-million dollar gigs, and not pittances like mine. Long story short, the project budget exceeded the estimate by more than 100%. Mark became extremely aggressive and feisty, and it was impossible to work or reason with him. I hired a Private Investigator to find out who this person really was -- like a Dr. Jekyl Mr. Hyde. Turns out that he had been sued for fraud, but more importantly, the whole worker's comp, fairness, ethical contractor, and so on, charade, was ALL ONE BIG LIE. It also appears that Mark may have left the Better Business Bureau due to bad reviews and that he may have hired a reputation defending company to increase his Yelp reviews to 5 stars by questionable tactics. Good Guy Builders license has been suspended for Worker's Comp violations and is under investigation. After my PI reported this, I found on the CSLB site: "License is under suspension for failure to comply with Workers Comp. A workers´ compensation certificate or exemption statement may have been received by the Board but not yet processed. Once the certificate or exemption statement is processed the suspension will be lifted retroactively to the effective date of the certificate or exemption statement. Ask the contractor for proof of worker's compensation and contact the insurance company to verify coverage." Here is the URL: https://www.cslb.ca.gov/OnlineServices/CheckLicenseII/LicenseDetail.aspx?LicNum=1016932 Please see image below. This is one of the greatest betrayals where I was charged an arm and a leg, and told a romantic story of workers being taken good care of, and so on, all the while, when Mark was simply pocketing the money that was supposed to cover his workers' safety and well being. Such greed, deception, and dishonesty, in my opinion, does not deserve a second chance. You decide whether you want to hire this company and deal with Mark. --- Addendum to Mr. Santosh R's note: 1. I am a real person. I was threatened by Mark that I would be sued if I posted anything negative on Yelp. 2. Yes, I did edit my posts before finally settling on one. Anyone in my position would do the same. 3. Finally, the facts remain unchanged. Good Guy Builder's license is under suspension and this may be independently verified on the CSLB website (see link). Likewise, the lawsuits against them may be independently verified. People like Santosh and Mark are the real culprits who boost their yelp ratings in a manner that skews it in their favor - by attacking anyone who posts negative reviews, and threatening those in dispute with defamation lawsuits. Do not believe anything Santosh or Mark say. The suspension is more than ample evidence that Good Guy Builders is a crooked business and not one that you should be patronizing.

    My wife and I wanted to update our fireplace hearth before our new gas fireplace insert arrived…read more After talking to other friends and reading several 5 reviews, I decided to reach out to Surface Masters. I knew I was in good hands when I drove to their Napa office and was welcomed in by Andrew and his assistant. They were so very welcoming! I explained what I wanted and gave them my measurements of my old brick hearth. Andrew entered the measurements in his computer and I had the estimate in my hands before leaving. The entire process was smooth. They came out to my house, took fine measurements, and built my hearth, then their install guys, Cesar and Marco arrived with the new hearth and all supplies/ materials. Both Cesar and Marco really care about their craftsmanship and it shows! They are very meticulous and fine detailed in every aspect of their craftsmanship! Their final completion turned out beautiful and my wife and I couldn't be happier! This was no simple job and I would hire Surface Masters again in a heartbeat! If you are looking for the best company in the bay area, look no further, you will be a happy customer! Thank you very much Andrew and all staff that helped create our beautiful new fireplace hearth!

Office staff are friendly and extremely knowledgeable about products and processes to give u a real idea about what to expect. Demo teams know what they're doing! Ours was a surface upgrade only and the team was able to get the old tile off and new plywood down without damaging our cabinets. Install was super slick and the results are perfect. These guys are the best.
