I feel very fortunate to have had Brownstein Construction, a licensed contractor, do a remodel on our home. I met Clark at the permit office, in passing, while seeking a permit. He overheard me sharing my project, and introduced himself. From there, he had a simple and straight-forward bid process, showed up to meetings on time prepared, and is a very good communicator. He's friendly, fun to work with, and no-nonsense. More than anything, he cares to get everything right and safe. Through our months of work together he would listen to my ideas, always working with me to make my dream home. All of my questions were treated with respect, and nothing was left undone. His team was creative and positive as they navigated any unforeseen hiccups. Most of all, every member of the team showed up with an open mind and integrity in their work. In working with a contractor, one has to be adaptable to their schedules. From the top-down, these guys give 100% everyday physically. As owners, it is our job to treat them as the peers they are: they should be allowed to take family vacations, pivot to other clients while subcontracting takes place, and they can get sick just like anyone. Marin is a very wealthy area, and I did not take for granted that these gentlemen would get up at the crack of dawn to be cognizant of commute traffic, to be most efficient with their time on the job. Similar to other counties, the permit process stinks. But the permit process should be no reflection of the contractors. Both contractor and owner have to be highly proactive in the permit process, given the broken system we are forced to use. I have already referred Brownstein Construction to family and neighbors. And I will certainly use them for future projects.

We have hired Brownstein Construction for the second time in about 6 months. The first job was a shower installation. We also used Brownstein Construction recently for some exterior work on our house. We are very pleased with both jobs that Clark and his crew did for us. The most recent job involved replacing quit a bit of exterior wood trim (mostly around windows) that had wood rot. They applied an anti fungal product where needed, caulked all joints (including joints between trim pieces that were not replaced) and, in addition to painting the new trim, painted all of the existing trim to help prevent additional wood rot from occurring. Clark also used upgraded wood of a better quality than the original trim. Even the type of caulk used was specific for this application. I really appreciate this type of attention to detail. Clark’s crew always showed up on time, worked efficiently, and always cleaned up at the end of the day. Clark would arrive daily to inspect the work and to make sure everything was being done to our satisfaction. The completed work looks great and we could not be more pleased. We highly recommend Brownstein Construction.
