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.
A little under a third of the housing here sits vacant at any given time, which is what you would expect where a lot of properties are not lived in year round. That matters for waterproofing because an unoccupied house is where a slow leak goes unnoticed for a season. Nobody hears the drip. The damage shows up as rot in the framing rather than a stain on a ceiling.
We build for that exposure: terminations detailed properly at walls and posts, drainage that actually moves water off the deck, and coatings 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 the plans 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.
