"Leo was very helpful and quick to respond. We’re happy with how our 2 bathrooms turned out. Project was completed within the time promised. Our only complaint is that the workers did not clean up very well. But overall, we’re satisfied and we’ll use them again. "

"Our kitchen always felt too small and cluttered, so we extended it into the unused dining space. DevArt8 Builders guided us through every step, from designing the layout to choosing materials. They added more storage that made the organization so much easier and improved the overall layout of the space. The team was professional, easy to work with, and kept everything on schedule."

"Green California Builders exceeded our expectations. We interviewed several companies, but they stood out from the start with their professionalism and honest, no-BS approach. What I appreciated most was their transparency—there were no hidden fees or vague answers. The project manager was always available to answer our questions, even on weekends. When there was a delay on a specific tile we had chosen, they let us know immediately and offered great alternatives. The final result is stunning. Our new bathroom has custom cabinetry, matte black fixtures, and this amazing herringbone tile wall that’s now my favorite part of the house. It’s rare these days to find contractors who are so detail-oriented and respectful of your home. If you’re thinking about a remodel, you won’t regret going with them."

"This was a second time we hired Hometech and Moses’ team. A couple of years ago we remodeled our home in LAH and had a great experience . After we bough our vacation home in Naples, we were glad to find out that Moses is working in the area, as it is difficult to find trusted builder , especially when you aren’t living in the area and doing this project remotely. Our Naples home, overlooking Aqua Cove is in great location, but design was too traditional and dated . We did complete gut remodel of 4 bed and 4 bathroom house approximately 4500sf, including changing the facade to give it more modern and CA look :) Definitely one of the kind houses in the neighborhood . As always, we were well informed about the progress, done a couple of sites visits during construction and the team was able to accommodate virtual meetings to fit our busy schedules . We can’t wait to spend this winter in nice warm weather enjoying our new home away from home"
