Deck Waterproofing in Cypress
Long-lasting waterproof coating systems that keep walking decks, roof decks, and balconies protected from water intrusion.
Deck Waterproofing detailsIn Cypress the Building Division sits under Public Works, which is not where most people go looking.
Takes about 30 seconds. No obligation, no pressure.
Small thing that wastes people's time: in Cypress the Building Division is part of the Public Works Department, not Community Development where most cities put it. It handles building, grading, water quality, and construction and demolition needs together. If you have been sent round in a circle asking about a deck permit, that is why.
The city covers 6.6 square miles and is essentially all land, with 16,272 households and an owner occupied rate of 68.1 percent. So most of the work here is single family and townhome: rear decks, entry stairs and balconies that have begun letting water into the structure below.
Flat ground is not the easy case people assume. On a slope, gravity does part of the job whether or not the detailing is perfect. On flat suburban lots the deck itself has to create every bit of fall it gets, and when a surface settles or a topping wears down, the water simply stops moving.
Standing water is patient. A puddle that sits for two days after a storm keeps a hairline crack wet the whole time, works its way into a seam that would shed a passing shower, and softens the plywood underneath before anything shows on the ceiling below. Ponding is the single most common thing we correct here.
The fix is fall, not film. We re-establish slope across the surface, set the drain or scupper at the actual low point, put metal with a drip at every edge, and detail the door thresholds and post bases before the system goes down. Coating a ponding deck without correcting the slope restarts the same countdown.

It is the problem. Standing water keeps every crack and seam wet for days instead of minutes, which is how a surface that sheds a shower fine still fails. Correcting the fall is the repair. Recoating over a ponding deck just resets the clock.
Yes. Shared stairs take constant traffic and wear through at the nosings and along the walking line first. We rebuild the worn sections, address any rust in the stringers or pans, and put a system down that is rated for foot traffic rather than a plain deck coating.
