Robyn S. says, "Strong structural contractor for major renovations, plans, and full finishes We hired Devco for a very large, complex renovation that included architectural plans, engineering, full permitting, and converting the home into two legal units. The project began in June 2024 and is now wrapping up punch‑list items. This was far more than a cosmetic remodel—it involved structural corrections, foundation work, seismic bolting, new systems, and coordinating with the City throughout the process. Devin and his team handled the heavy structural scope well. Underpinning, new foundation sections, plumbing, electrical, HVAC, framing, and major system upgrades were all completed as needed. Devco also managed the plans and permitting process smoothly, which was a major part of the project. In addition to the structural work, Devco completed all the interior and exterior painting, all new windows, both kitchens and bathrooms, finishes, appliances, and the installation of electric fireplaces. We worked together throughout the project to plan the finishes, and the team was flexible and collaborative as decisions evolved. As with most large renovations that span many months and involve significant structural work, some finish‑level items needed touch‑ups once the major work was complete. Devin has been responsive in addressing the items we’ve identified, and we appreciate the follow‑through. Overall, Devco is a strong choice for projects that involve structural work, foundation corrections, engineering coordination, and full‑scope renovations. We’re happy with the transformation of the property and grateful for the effort the team put into getting it across the finish line."See more

Sue M says, "Promodeling updated our 1940's old-school tiled bathroom which involved replacing tiled walls and stall shower with cultured marble, texturing and painting the walls and ceiling, retiling the floor, refinishing the tub, and installing a new vanity, medicine cabinet, shower door, trim kits, and fan. Alexandra, the Project Manager, was easy to work with. She communicated clearly, returned calls and texts promptly, took time to answer my questions, and was very personable. Brian, the crew leader, was also easy to work with and was patient and thoughtful in explaining things I asked about. He and the crew were friendly, respectful, and cleaned up well each day. Everyone was very attentive to making sure the job was done the way I wanted it, and when I asked for some wall texturing and painting touch-ups, they were taken care of quickly.I felt good about Promodeling's price. The estimated cost was nearly the same as the final cost. I did authorize a change order to replace an old plumbing part, which was a relatively small cost. I had one bid from another company that was considerably lower, but the estimate was much less detailed and I don't think they anticipated the full scope of the work. Another company's bid was much higher, and the company had their preferred vendors and products, which I felt might limit my input into the materials. I am happy I chose Promodeling.I gave Promodeling a 4, rather than a 5, since I did need to ask for touch-ups the crew hadn't noticed. Also, the trim painting (window frame, and door and frame) was just OK and not as smooth as I might have done myself. I'm sure I could have asked them to redo it, but chose not to. I admit to being a picky painter! If I have another project, I will definitely contact Promodeling again, and I certainly recommend them to others."See more

FAQs

Answers to commonly asked questions from the experts on Thumbtack.

There are several great options for waterproof basement flooring. For example, epoxy floors are waterproof but are thicker and sturdier than paint. Make sure the concrete substrate has been prepared for application. 

Tile is a designer’s dream, giving you a moisture-resistant surface that’s infinitely customizable. Rubber sheets or tiles are also good waterproof options, particularly for playrooms, workout areas or laundry rooms. 

Vinyl tiles and planks imitate wood or other materials very convincingly, provide moisture resistance and last a long time. And sheet vinyl is affordable and a great waterproofing solution for those in need of quick fixes.
