We Meet Your Needs

At Capital Deck & Stair, we take pride in adapting our services to the needs of our customers. Sure, the basic service we offer is waterproofing, but that can take on many different forms. Sometimes it will mean waterproofing surfaces as part of a new construction project, while other cases will involve restoration waterproofing.

Where other waterproofing contractors in Los Angeles may only handle one type of job, we can do just about everything imaginable within the waterproofing space. From the waterproofing of pool decks, roof decks, balconies, walkways, and garage floors to the installation of magnesite stairs and magnesite decking, our portfolio of services is quite diverse. We provide coatings that offer not only waterproofing but also UV protection for your decking material and inserts designed to stop leaks in wet weather.

When you work with Capital Deck & Stair, you get a general contractor who can help with above-deck waterproofing, to protect your deck boards for the long-term, and under-deck waterproofing. We can waterproof tile, stone, brick, slate, and wood surfaces. Only the most effective products are used, including Loctite, a clear silicone and multi-purpose adhesive and sealant that creates a waterproof protective seal that is ideal for metal, glass, rubber, tile, and porcelain.
