Deck Waterproofing in Rolling Hills Estates
Long-lasting waterproof coating systems that keep walking decks, roof decks, and balconies protected from water intrusion.
Deck Waterproofing detailsA contract city on a peninsula with documented landslides, including one on Peartree Lane in 2023.
Takes about 30 seconds. No obligation, no pressure.
On ground like this, a deck is part of the property drainage whether it was designed that way or not. Rolling Hills Estates occupies the northern side of the Palos Verdes Peninsula, an area with a history of documented landslides, including the Peartree Lane landslide on July 8, 2023, which destroyed several homes in the city.
Water shed off an edge and left to soak in is exactly what you do not want on a slope with that history. We design the repair so water is collected and taken somewhere deliberate, then waterproof the surface to match. Doing it the other way round, coating first and worrying about where the water goes afterwards, is how a deck repair becomes a hillside problem.
Of the 3,220 housing units in the city, 89.8 percent of the occupied ones are owner occupied, so this is almost entirely private property, often with terraces and stairs stepping down a slope. Those structures carry real span, and span means movement.
On sloping lots we look under the deck first. The underside tells you whether the framing has been taking water, whether the hardware still has section, and whether the posts and footings below are dry. None of that is visible from the finished surface.
Roof runoff belongs in the conversation too. Downspouts discharging onto a terrace, or into the grade at the head of a slope, undo a good deck repair from outside the deck.
