Larry T. says, "Recently had a pedestrian door installed into the side our level one garage in LA. Ethan was the PM assigned to the project and was very responsive, communicative throughout the design, permitting and construction. I would highly recommend working with Built To Perfection and Ethan again on future remodels."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.
