Ocean on one side, mountains on the other, and a coastline that finds every gap in a deck.
Malibu is bounded by the Santa Monica Mountains to the north and the ocean to the south, with Topanga to the east and Solromar to the west. Decks here take salt air continuously and storm driven rain seasonally, and the combination is harder on a waterproof system than either one alone.
Salt keeps working on fasteners and flashing while wind pushes water uphill into laps and terminations that would never leak on a sheltered street. Two forces attacking different parts of the same assembly, which is why a repair that only addresses the surface does not last here.
A little under a third of the housing sits vacant at any given time, which is what you expect where many properties are not lived in year round. That matters, because an unoccupied house is where a slow leak goes unnoticed for a season. Nobody hears the drip, and the damage arrives as rot in the framing rather than a stain on a ceiling.
About 70 percent of occupied units are owner occupied, and density is low at roughly 334 units per square mile. These are large individual properties: view decks, ocean facing terraces, long exterior stair runs down a slope, and the guardrails that go with them.
We build for that exposure. Terminations detailed properly at walls and posts, drainage that moves water off the deck deliberately, and coatings and metalwork chosen for a marine environment rather than an inland one.

Learn more →Malibu routes plans through the Building Safety Division first, which stamps approved before staff forward them to the other departments for their final stamps, with Planning stamping last. On buildings with three or more dwelling units, exterior elevated elements must be inspected by a California licensed architect or a California licensed civil or structural engineer. We work from that inspection and carry the repair through the stamp sequence.

Fast, no-obligation local quotes.
For buildings with three or more dwelling units, exterior elevated elements must be inspected by a California licensed architect or a California licensed civil or structural engineer. We take that report and carry out the repairs it calls for.
It changes how long a leak runs before anyone notices. Roughly 31 percent of housing here is vacant at any time, and an unoccupied house turns a small leak into framing damage over a single wet season.
Malibu stamps plans through Building Safety first, then forwards them to the other departments, with Planning stamping last. Knowing that order keeps a set from sitting in the wrong queue.
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.
