Stop leaks, dry rot, and structural damage with a durable, code-compliant deck coating system, backed by our 8-year warranty.
A deck takes constant abuse from sun, rain, and foot traffic, and once the waterproof layer fails, water reaches the structure underneath. Left alone, that leads to dry rot, rusted framing, and repairs that cost far more than the original coating.
Capital Deck & Stair installs proven waterproof deck systems that seal the surface, shed water to proper drainage, and stand up to daily use. Whether it is a walking deck, roof deck, or balcony, we match the right system to your surface and back it for 8 years.
