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

Elizabeth S. says, "In the past few years, as a result of a burst water pipe and the Eaton Fire, I have dealt with many contractors of all price points, specialties, and size. Adrian impressed me from the start with his responsiveness, clear communication, and efficient delivery of a detailed proposal and quote. We hired him for the remodel of a Jack & Jill bathroom, a tight, confounding space with too many doors and a strange configuration. Adrian visited the space and quickly responded with digital renderings (including a 3D model). He asked for our input and incorporated it seamlessly and faithfully, so that we quickly had an executable plan. Adrian worked with us to design and build a new bathroom that fit our budget and delivered all of the features and design elements we hoped for. Throughout the process, Adrian updated us daily and visited the site frequently to ensure everything unfolded according to plan. I could not be happier with the final result, not can adequately express what a pleasure it was working with AAA. Adrian shouldered the burdens of construction stress and did so with unfailing charm and optimism. His dealings with us were always honest, and, if things hit a snag (as they always do in construction projects) Adrian reached out immediately and with a solution in hand. I cannot recommend this company highly enough. I have no doubt, because of his professionalism and skill, Adrian will be in high demand. He is a rarity in the remodeling industry and a gift to homeowners looking for competent, reliable, creative contractors"See more

ANGELO V. says, "Golden Age Builders handled a balcony repair for me involving structural wood rot and hidden joist damage — the kind of job where you don't know how bad it really is until they open things up, which is nerve-wracking as a property owner. They got that, and it showed in how they worked. They communicated clearly on timelines, costs, and any changes along the way, so nothing came as a surprise. Their project management was solid — permits, scheduling, and daily progress were all tracked closely, and the work kept moving. When they ran into unexpected conditions once the balconies were opened up, they adapted fast without stalling the job or padding the bill. Pricing stayed reasonable throughout, and I never doubted their integrity. Highly recommend for anyone dealing with balcony or structural repair work."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.
