Seems like our job was shoved in as a quick after thought. Contract states: "The roof will receive all new metal pipe jacks, nosings, hoods and bases and metal will be painted to match roof color. New eyebrow vents at the upper ridge area as well as proper ventilation". What I found when I climbed on the roof is that NONE of the pipes, vents etc. had been replaced except one piece. I would rather be told the truth, that there was a mistake made rather than have a professional lie by omission : Asking for house paint but to paint the 12 year old plastic and metal parts. The paint is now chipping off, there was no caulking added. I finally climbed up on the roof because the new gutter that was installed pulled away from the eave, bowed out and for the past two months there has been a water fall from the gutter, down the side of the house. And on to the front porch at the exterior wall. When Dan came and climbed on the roof to check he pulled the gutter away and said they would just have to nail it back in, that the gutters needed to be cleaned. Told him that Didn't sound right because a gutter of 12 years got plugged every year with no issues. I found the guys who'd done the job on the gutter had used 1/2" screws? and the hangers weren't screwed in at all! As far as the leveling of the new gutter 60' gutter, there is water pooling in the middle. The gutter should have been done in two parts like the original one and leveled to its own drain at each end of the home. Finally, we had a leak and that's why we had the roof redone. Still have same leak, same spot in the ceiling. Dan came buy and told us the heating vent was the issue and it needed a hood. Haven't heard back from Dan and its been several weeks since he climbed on the roof Ther

David Mulligan is as good as it gets when it comes to a general contractor in the Marin area. If he…read morehas availability to do your project you must hire him. PROJECT DESCRIPTION: This was my first remodeling project and I chose David and Builders of Marin after interviewing ~4 different contractors. The project was a to-the-studs renovation and expansion of a ~1,500sqft, 2 bed, 2 bath ranch home into a ~3,500sqft 4 bed, 4.5 bath contemporary home. Complicating the build was (1) that the house was on a steeply sloped, small lot, (2) needed an entirely new foundation, and (3) was on a narrow street with no parking. WORKING WITH DAVID AND BOM: Working with David on this project was a pleasure. I hear friends describe their interactions with contractors and consider myself very lucky that I was able to work with David and his team on my project. If I ever do any remodel I will only do it if I can get David to do the work, and if I ever buy another house I will get David to visit the property with me. In fact, I would probably hire David first and then shop around for an architect. David is highly responsive, detail oriented, and does what he says he will do every time. From a work-style perspective, David is the ultimate high-integrity professional -- which is difficult to find in the construction industry at times. HOW DAVID AND BOM ARE BETTER THAN OTHER CONTRACTORS: David and BOM are better than other contractors based on three very important qualities: estimate accuracy, follow-through and execution, and crew / construction quality. ESTIMATE ACCURACY: One of the most difficult things about a high-end residential construction project is getting anyone to tell you how much anything costs. David will do the work to come up with an accurate quote, and will give you a reasonable, sober estimate as to how much different scope changes will change the budget. He brought our project in on-time (incredibly rare) and on budget (when adjusted for us changing the project scope and adding ~700sqft midway through). He does not over-promise or under quote (as many GCs do), and also doesn't mark-up everything by 30% (as many GCs do). Furthermore, if he finds cost savings midway through the project he will help you realize those. FOLLOW-THROUGH: As mentioned above David is accurate at estimating project costs and timelines. He is able to BE accurate because he has the crews and sub-contractor relationships to get the work done on time. Unlike many GCs who over-extend themselves during good construction markets, David has a number of quality crews with incredible site foremen (Kim was ours -- the best!) and is able to realistically budget their time to avoid delays. Furthermore, David believes in doing what he says he will do and will make the construction personnel be there to get the work done. CREW / CONSTRUCTION QUALITY: David believes in retaining the best people and has been working with many members of his crews for 20+ years. Many of his master carpenters started out as unskilled labor with him decades ago, and he has taught and mentored them up himself. What this has allowed David to build is a team obsessed with construction quality that knows how to do things the right way, and can get things done quickly. Furthermore, he has a deep bench of talent that he can put to work on projects to get them done on time, the right way. The commitment to finish quality from David and his whole crew is maniacal, and they are able to pull-off flawless contemporary designs that require high build quality. I would like to call out Kim, Omar, Jesus and the whole BOM team who worked on my house -- they are all incredible craftsmen and wonderful people to be around. For all of these reasons and many more, I wholeheartedly recommend David and Builders of Marin for your next project. I would also recommend you get on his docket early -- he gets booked up fast!

We decided to buy an old house on a large piece of land where we could build our forever home. We…read moreknew the house was old, but we did not realize how bad it was. Little did we know at the time, what a massive undertaking this project would be. After talking to several contractors and on the recommendation of our Architect, we selected Builders of Marin to build our home. We picked David because there was something honest about him. What you see is what you get. Having experienced other contractors in the past, that is a huge positive to us and not something we normally encountered. The original plan was to expand onto the existing house but we realized that everything was rotten after decades of neglect by the previous owner and ended up tearing everything down back to dirt and started over. This turned out to be bigger than we ever planned or budgeted for. Along the way, David was able to guide us though all of it. He stepped in and problem solved a range of issues, including many interior design issues that was not even his responsibility. From the mundane of relocating an outlet, to the life changing "holy sh*t, we are having twins", David we need an extra bedroom, David and his experienced crew, handled it all to made our dream on paper become a reality.

We had a relatively straightforward although far from small project of a complete bathroom refresh…read more We interviewed a few contractors and all of them gave us estimates in the same range. What impressed us about Greenport from the very first conversation was their professionalism and attention to detail. Once we started working with them we became more convinced that we'd made the right choice. The best aspect of working the them was their full transparency, starting from the initial contract through the project completion, which helped us stay within our budget. The communication was excellent in all stages of the project. Of course, there were hiccups and misunderstandings but they all were resolved promptly and to our full satisfaction. We've always felt heard and in the center of their attention even though they had several other projects going on at the same time. The crew was very professional and efficient. All the work was completed according to the schedule and in a few cases slightly ahead of it. The quality was was excellent across the board, including the rough work, finish and the custom-built vanity. Overall we got exactly what we wanted without any headaches and at a pretty good value. We will definitely consider working with Greenport again when the need arises.

This was my first large-scale remodeling project as a homeowner, but as an interior designer, I…read morehave a lot of experience with general contractors. I was truly impressed with Greenport's team. They went above and beyond in planning, budgeting, quality, and communication. I cannot recommend them highly enough. They had a uniquely detailed project tracking method that I'm only used to seeing in T&M billing. They produced daily logs I could access from anywhere an while I appreciated the detail, it became a lot to track, so they switched to a weekly report that included accomplishments and upcoming tasks. They also provided a project schedule before starting, which was incredibly helpful. They were flexible about product choices and design. Most importantly, their craftsmanship was top-notch. In my experience, some people lose momentum toward the end of a project, but they stayed committed and finished strong. They created their own punch list that covered everything in mine and then some and walked me through each room to ensure everything met my approval. I did have one issue with a drawer a few weeks after they were gone but they came back and fixed it the next day, which is unusually fast after a contractor has gotten their final check. I have to say, regarding pricing, they aren't cheap. They were the second-highest of the initial estimates I received. They provided the estimate for free but they charged to give me a "fixed-price quote", which was well detailed and clear. I don't know if they do this for every project, but they gave me an agreement for a pre-construction planning budget. I was a little bit nervous about paying for a lot of planning and it did extend the timeline for our intended start date by a couple of weeks but they got through it relatively quickly all things considered. It was eye-opening as to why i've seen other GC's charge so much in change orders. Missing details in the plans can be very expensive, and they might try to find some "change order" to recoup costs. But that extra time the guys at Greenport spent helped to get everything done right the first time, on schedule, and on budget, which is a rare thing in construction.

They also remodeled our entryway and front porch, giving our home fantastic curb appeal and making a great first impression. We are still absolutely loving the results today. The addition exceeded our expectations and has truly transformed both the look and functionality of our home. From start to finish, the team was professional, attentive, and delivered outstanding craftsmanship. The quality of their work has stood the test of time, and we continue to enjoy the improvements every day. What has impressed us even more is the continued support after the project was completed. Recently, we experienced an issue with a tub leak and reached out to John. He responded promptly, sent his plumber to assess the problem, and discovered that the tub fixture was still under warranty. A brand-new replacement fixture was ordered and installed, resolving the issue quickly and professionally. John is excellent with communication, follow-up, and follow-through. He truly stands behind his work and takes care of his customers long after the project is complete. We also have to give a special shout-out to Ladybug, John's friendly dog, who always brought a smile during the project! We highly recommend John G. and G Family Company to anyone looking for a contractor who delivers exceptional craftsmanship, professionalism, reliability, and outstanding customer service.

After interviewing multiple contractors, G Family stood out immediately as the only team that came on site, dug into the details, and worked to understand our intent--not just replicate the designs. Their honest, up-front pricing was a major differentiator. We received a clear, comprehensive estimate with everything included, while other bids had many "TBD" items that weren't part of the real number. When I factored in those gaps, G Family was very competitive. They were also incredibly collaborative in helping dial in the details: when certain elements exceeded our budget, they provided practical alternatives and helped create a phased plan so we could add features later. Execution matched the planning. Communication was clear, updates were frequent, and when inevitable snags arose, they took the time to explain options and trade-offs. They even diplomatically guided me away from a bad design choice using their experience--absolutely the right call in hindsight. They also handled HOA-required changes without billing extra or anything like that. G Family isn't the cheapest, but the value is worth it. They were accountable, invested, and genuinely treated the project like it was their own backyard. Beyond the craftsmanship, they're just great, down-to-earth people to work with. Our once-underutilized yard is now a beautiful outdoor living space we use every day. I highly recommend G Family Construction!

When this started, I thought it could get done in under 2 months.

It got done and the deck looks good so I'm thankful for that. Sharing this here so that folks come into projects with eyes wide open to the fact that things take way longer and costs, which are already astronomical, are likely to be even higher when all is said and done.
