Two miles of beachfront means salt air on every deck, every day, whether it rained or not.
Manhattan Beach runs along roughly 2.1 miles of beach, and the ocean keeps the climate moderate year round, with an average high of 69.1 degrees and an average low of 56.4 degrees. That mildness is deceptive if you own a deck here. Salt laden air works on coatings, fasteners and flashing continuously, and it does not wait for the rainy season.
We see it most at the edges, where a deck meets a wall, a post penetrates the surface, or a stair ties into the structure. Those are the details we rebuild properly rather than patching over.
The stock here is dense but owner heavy: 14,994 housing units, with 67.3 percent of occupied units owner occupied. Small lots, tall houses and roof decks, and stairs climbing three levels rather than one. That geometry puts the waterproofing at transitions and terminations, not in the open field.
Corrosion is usually the first honest signal. A rust stain bleeding through a coating means the metal under it has been wet for a long time, and the coating is being held down by hardware that no longer has full section. Replacing that hardware is not an upgrade, it is the repair.
On tight lots the logistics need planning as well. Staging, tear off and disposal on a small parcel with neighbors on both sides is a scheduling problem before it is a construction one.

One local wrinkle worth knowing: the Waste Management Plan tickets must be emailed in before the permit is finalized, which catches people out at the end of a job rather than the start.

Because it is not the temperature doing the damage. The city fronts roughly 2.1 miles of beach and the air carries salt year round, so fasteners, flashing and coating edges are under constant attack whether or not it rains.
Waste Management Plan tickets. They must be emailed in before the permit is finalized, so we handle them alongside the work rather than discovering the problem at closeout.
Yes. Of 14,994 housing units, 67.3 percent of occupied ones are owner occupied, so this is mainly private decks, roof decks and stairs rather than shared apartment walkways.
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.
