Deck Waterproofing in Cerritos
Long-lasting waterproof coating systems that keep walking decks, roof decks, and balconies protected from water intrusion.
Deck Waterproofing detailsCerritos runs on the LA County building code, with County-contracted staff handling plan check and inspection, which surprises people.
Takes about 30 seconds. No obligation, no pressure.
Cerritos adopted the Los Angeles County Building Code as its own building code by ordinance, so plan review and inspection follow the County rules rather than a separate city code. Owners are often surprised by that, and it is the kind of thing that costs a week if a contractor assumes otherwise and submits to the wrong place.
Roughly three quarters of occupied homes here are owner occupied, so most jobs are single family: a rear deck over a patio, an entry stair, a balcony that has begun letting water into the wall behind it. Cerritos is one of the Gateway Cities of southeast Los Angeles County, on flat ground, so failures here are about slope and drainage rather than hillside runoff.
Flat ground failures follow a pattern. The surface was built close to level, water sits instead of running, and the standing water finds the one termination that was never detailed properly. Give it a few seasons and the sheathing under that spot is soft while the rest of the deck reads fine. Owners often describe it as sudden. It was not.
Because owner occupancy is high, most people here are paying for a repair they intend to live with for a long time. Tearing off and correcting the slope costs more on day one than another coat, and it is the only version still working in ten years.
We also fabricate and set stairs, so where an entry stair or a rear stair has gone past repair, replacing it in iron or precast is on the table rather than patching it for another year.

On flat ground the water usually sits rather than runs, then finds one bad termination and travels along the framing. The visible damage shows up well away from the actual entry point.
Yes. We fabricate custom iron and precast staircases as well as waterproof them, so when an entry stair is past repair we can set a new one rather than sell you another patch.
