Durable waterproof coatings that protect walking decks, roof decks, and balconies from water intrusion.

Coastal Orange County, and home to Leisure World, one of the first 55-plus communities in the country.
Coastal position means salt air working continuously on fasteners, flashing and the edges of a coating, which is the sort of damage that does not announce itself until a detail lets go. Seal Beach occupies the westernmost corner of Orange County, just across the county line from Long Beach and San Pedro Bay, with Huntington Harbour and Sunset Beach to the southeast.
The city is also home to Leisure World, opened in 1962 as one of the first age segregated communities in the United States for residents over 55. Community property of that kind comes with its own approval expectations alongside the city permit, and with residents who need access maintained throughout the work rather than a walkway closed indefinitely. We plan for both.
That resident profile also changes the specification. Slip resistance on a walkway or a stair is not a nice extra where the people using it every day are older, and neither is a continuous, properly anchored handrail. We build for the traffic that is actually on the surface.
There are 14,645 housing units in the city, 73.9 percent of the occupied ones owner held, so alongside the community property there is a lot of private deck and balcony work. Coastal exposure hits those the same way: the coating looks tired, and the metal underneath is what has actually failed.
Salt corrosion is invisible until it is structural. It attacks rail base fasteners, the pan under a stair tread and the edge flashing behind the coating. We pull a fixing and look rather than judging the assembly from the walking surface.

Yes. Community property here typically has its own approval process alongside the city permit, and residents need continuous access, so we prepare both submittals and phase the work so no one loses the route to their door.
It decides the metal. Salt corrodes fasteners, rail bases, stair pans and edge flashing continuously, and none of that shows on the walking surface. A detail specified for an inland property has a shorter life here, so exposure drives the material selection.
Yes, and it should be. A traffic rated system with an aggregate broadcast or a textured finish gives a walkway grip that a smooth deck coating does not. On property used daily by older residents that is part of the scope, not an upgrade.
A professionally installed waterproofing system typically lasts many years. Capital Deck & Stair backs most projects with an 8-year warranty on workmanship, and proper maintenance can extend the life well beyond that.
Cost depends on the surface size, condition, and the coating system required. We provide a clear, itemized quote after a free on-site inspection, with no obligation and no pressure.
Most residential decks, balconies, and stairs take about a week from start to finish, depending on prep, repairs, and weather. We give you a firm timeline before work begins.
