Deck Waterproofing in Brea
Long-lasting waterproof coating systems that keep walking decks, roof decks, and balconies protected from water intrusion.
Deck Waterproofing detailsA hot-summer Mediterranean climate that spends months quietly working a deck surface apart.
Takes about 30 seconds. No obligation, no pressure.
Brea has a hot summer Mediterranean climate, and that pattern is harder on exterior decks than the occasional storm is. Long dry heat cycles a surface every single day, and the movement concentrates at the edges, the posts and the joint where the deck meets the building. By the time the rain arrives, the openings are already there.
Sun does more than move things. Ultraviolet breaks the topcoat down: it chalks, it loses its stretch, and a coating gone brittle cannot bridge the crack it is sitting over. You can see it on any west facing balcony where the color has flattened and the surface has checked into a fine pattern.
About 60 percent of occupied homes in Brea are owner occupied. Most of what we do is single family and townhome work: a rear deck, an entry stair, a second floor balcony marking the wall underneath, a common stair shared by a row of attached homes.
Balconies over living space get particular attention, because that is where a small leak becomes a framing problem quietly. The usual entry point is the door threshold. With no pan under the door and no fall away from it, every storm drives water into the sill and along the top plate, and the ceiling below reports it a year later.
On stairs we do more than coat. We fabricate custom iron and precast concrete stairs, so where a stringer has rusted through at the base or a run of treads has been patched to death, replacement is a real option. Getting the connection, the fall on the tread and the transition into the landing right at the same time keeps new work from failing the same way.

A local crew looks at the actual deck, and the quote comes back itemized.
It is the warning stage, and the cheapest stage to be in. A coating that has chalked and gone brittle under sun has lost the flexibility it needs to bridge movement. Dealing with it now is a recoat rather than a rebuild.
Because the threshold is the lowest, busiest and most penetrated part of the assembly. Without pan flashing under it and fall away from it, water sits at the sill in every storm and works into the framing behind.
Both. We fabricate custom iron and precast concrete staircases, so a stair that has been patched repeatedly, or one where the stringer has rusted at the base, can be replaced outright and detailed into the waterproofing.
