"Just completed our 4th (large) remodel project with Marc and his team - ripped all carpet out of our home and replaced with hardwood flooring. My experience(s) with Good Guy have always been stellar. Fantastic craftsmanship, cordial and polite craftsmen assigned to the project, very efficient (entire project done in 2-1/4 days). They were meticulous in keeping the house clean & clean-up at job completion was outstanding - all the while being very cautious in our Covad-19 restrictions. Another important thing to consider when hiring a contracting firm - how often do you get a "cost-conscious" contractor that will manage the project with you checkbook in mind??"

"Good Guy Builders company’s name reflects the only way they conduct their business. Their ownership and team are Honest, Respectful, and a tremendous compliment to the renovation of our master bathroom.
Mark and his team are exceptional. We did not have the ability to convey how to create what we wanted for our bathroom. He was the architect of our vision. A methodical and thoughtful approach. He exceeded our expectations."

"We hired Good Guy Builders for a small commercial renovation in a preschool. Mark and his crew did an excellent job of delivering a high quality result within tight constraints, including a short timeline and an open program. Mark is an efficient and communicative manager, so we always felt like we understood where the project stood. Having worked with other contractors on commercial renovations, Mark stands out a true professional who works for the best interests of the client."

The pictures are worth more than a 1000 words.You guys are quite extraordinary to have one another along with miss Fanny keep in’ y’all at bay. You are the differentiator. We are very fortunate to be partnering with you. Thank goodness for Steve finding you on Nextdoor.com. Greatly appreciate every detail and exceptional thorough approach of how you manage your business. And, providing helpful solid solutions. Stepping outside of the box. A rare gem! Methodical and thoughtful. A tremendous compliment to your industry. "

"We used Good Guy Builders to remodel our master bathroom in our vacation home in Napa and couldn't be happier with the process and results. The prospect of doing a remodel from afar was initially daunting, but we were put at ease by the company's expertise in remodeling second homes as well as their transparency in regards to projected time and costs. The owner, Mark, was extremely efficient and organized at managing and driving our project and even assisted with the design. Communication was excellent and we received daily updates and photos so were always kept in the loop even though we were mostly offsite. Mark and his team were professional, trustworthy and performed high quality work, and we wouldn't hesitate to recommend them."

"We live among the Redwoods, where the environment, though beautiful, is persistently damp. Over a period of many years, our deck and basement suffered severe damage from dry rot, wet rot, termites, and beetles. Desperate to repair/replace these failing structures, we sought bids from a number of contractors. However, we were most impressed by the professionalism and "can-do" attitude demonstrated by Mark, the owner and operator of Good Guy Builders. From the beginning, we were pleased with the terms and conditions of the Service Agreement and, as the project progressed, we received daily progress reports.
The transformation has been unbelievable. We watched in awe each day as John and Cliff, the builders, created new and beautiful masterpieces for us! New walls, new windows, new ceilings, new stairs, new decks, new railings, new gates. Our basement can now be lived in, and offers beautiful views onto a new lower deck and the surrounding Redwood forest. The upper deck has now been fully rebuilt. The design is attractive, classy, and spacious...and it is extremely well-constructed.
Today, we feel safe and proud because of the masterful work accomplished by this team, Thank you, Mark, John, and Cliff!"

"Mark did a great job on helping us renovate our kitchen, bedroom and deck. He's knowledgeable on home construction and we will hire him again."
Douglas M. (08/24/2018)
"What can I say about Mark and Good Guy Builders that hasn't been already said in most of these reviews? While I've never been a consumer of their services, I have worked along aside him as a design consultant and have prepared construction documents for several of his high-end projects in Napa. Working with Mark is unlike working with any other building contractor professional that I've experienced to date. Forget the stereotypes and the cliches that go along with "contractors." I consider Mark the upper echelon of professionals, and most other contractors should strive to up their game to his level. Mark is among the most responsive, transparent, clear communicating, involved, collaborative, accountable, honest, and creative builders I've ever worked with. He makes my job easy, with photos, sketches, and complete ideas in a most succinct manner. He actually answers his phone, returns phone calls and emails in a timely manner, and provides a clear path forward in all situations. I only wish we had a "Good Guy Builders" in my area, as I would recommend them to all of my clients, and as a die-hard DIY'er, would hire them myself without hesitation or concern. In my opinion, if you want the best experience you can have with a contractor, hire Mark and Good Guy Builders."

"My husband and I were in a horrible car accident this past June and I sustained crushed feet. I realized pretty quickly that I was facing many months in a wheelchair and that our home was filled with obstacles. While in the hospital, I called several contractors looking for support to do a bathroom remodel on very short notice (as I really needed it completed before I could return home and shower). Everyone I called was either booked out too far or they didn't return my calls. Mark answered the call on a weekend and he was the first willing to listen to our situation and needs and then agreed to do everything he could to squeeze our project in to his already very busy schedule. He and his crew were prompt, reliable and always professional. Mark provided nightly emails with pictures and reviews of what was completed each day and he was always easy to reach by phone or text to answer questions or check-in. We are happy with the job they completed, turning our raised bathtub into a beautiful walk-in (roll-in) shower. We highly recommend Mark and his team. And I will be forever grateful for Mark's empathy and willingness to make it all work."

"After having had three other bids, I decided on the Mark and the Good Guy Builders to fix/remodel my dad's house in Petaluma and they did a great job! Mark worked with me to get the most done within our budget. He kept in good contact with me and I had updates consistently on the project while I was out in Colorado. For everything that had to be done and having to deal with some difficulties and miscommunications, the end result is just what I was hoping for. Thank you to Mark and his team of "good guys". I'm very happy to have gone with them, they were the best decision!"
Jacob N. (12/06/2017)
"Mark and the Good Guy Builders were a huge help to me as I bought my first home. I'm actually not sure that I would have been able to successfully close without them. Not only did they perform a very large renovation (including knocking down load bearing walls, installing a new bathroom, electricity/plumbing work), since this was my first construction loan, he walked me through part of the financing and bureaucracy so I knew what to expect and met my deadlines. He went above and beyond the duties of a general contractor and still keeps in touch. I highly recommend him. Thank you, Mark!"
Monica M. (12/05/2017)
"After hiring bad contractors who slowed my project by 4 months I contacted Mark. I normally don't write reviews but Mark and his team went above and beyond. Mark also helped me with sub contractors who tried cutting corners and spoke directly to their boss. As an architect its very rare to find a trustworthy builder who cares about the quality of their work, is knowledgeable about California building codes, and most importantly commits to finishing on time."
Dave T. (03/16/2017)
"We contracted with Mark after responding to his Craiglist advert. Our project was a 'down to bare walls' reconstruction of our (very) dated kitchen. The project involved demands for numerous skill sets (demo work, plumbing, heavy electrical, lighting design/installation, drywall install & texturing, painting cabinet/drawer selection purchase & installation, overall design of kitchen and ALL of the needed coordination involved in a project of large scope). Mark and team - Mike, Fernando, Gill, et.al. were courteous, professional and extremely meticulous in every aspect of the work. One other thing of note that I must mention - when was the last time you worked with a contractor that exhibited cost awareness?? Mark did so and we feel we got the highest quality materials AND saved (literally) thousands of dollars. When you have a contractor who is spending your money as if it was his - you lucked out. We lucked out with Mark and his team and heartily recommend him/them for projects of any scale/size. We (my wife and I) are thrilled with the finished project and urge Mark to post some pics for others to garner an appreciation of the quality workmanship you will receive from Good Guy(s). We would not hesitate to be enthusiastic references to future clients of Good Guy(s).
Matt and Joanne S. (02/02/2017)
"Mark (the "Good Guy") is: Prompt. Punctual. Reliable. An excellent communicator. Skilled. Meticulous. Conscientious. Thorough. Creative. Reasonable. Practical. Adaptable. A Good Guy. We had a general idea of what we were after, but were unsure what the possibilities were. Mark was good at patiently explaining various approaches and coming up with ideas and considerations that hadn't occurred to us. The end result is wonderful. We've already recommended him to one of my neighbors, and are going to invite him back to install a new floor for us."
Amy S. (02/11/2017)
"Wow what can I say, where to start? I feel as if we have adopted Mark into our family since one project has led to the next and next. We hired Mark to do the impossible renovation, with some pretty unconventional style requests that took a lot of ingenuity to bring to life. Our project is 100 times better than I imaged it could be. Since our mini house make over is completed we have hired Mark back to install doors and build in custom frames around them. Then retaining wall work. Then Install and plumb a custom coffee maker. The list goes on and on. It is years of projects just getting handled one after another with the result always the same. Quality Quality Quality and working with us when cost cutting was in order on projects. I recommend him to all my family and friends. The only downside is sometimes you have to wait to get on the schedule but he is worth the wait."
Melina R. (05/19/2016)
"TRULY....A breath of fresh air and godsend!!! In this cut throat business, I've had more than my share of remodeling nightmares and Mark stepped in and took on a project that most would walk away from. I seriously don't know what I would of done without him! Mark is extremely knowledgeable in every trade, leaves no detail to chance and I have learned so much from working with him."
Lisa T. (12/29/2015)
"Mark was a blessing in disguise. After getting no response from 2 other cement contractors in Napa to help me with my porch and foundation, by chance I called an old high school friend who referred me to Mark. He was very punctual and communicated to me every aspect of the job. He even helped me reroute my cable under the house at no charge. Mark is very educated and knowledgeable in construction and would recommend him to anyone."
Jim S. (04/03/2016)
"Mark has done several jobs for us at our Napa home. He makes sure the work is very specific up front so there is not confusion and is big on setting dates for completion. His work is top notch and his prices are very fair. Most recently he re-tiled a bathroom and it looks great. I highly recommend him."
