Valley floor below, Santa Monica Mountains above, and nearly six in ten households renting.
Part San Fernando Valley, part Santa Monica Mountains: work in Sherman Oaks splits cleanly along that line. Up in the hills it is cantilevered decks and terraces where drainage has to be directed away from the structure and the slope behind it. Down on the valley floor it is ponding, poor fall, and surfaces holding water for days after a storm.
The neighborhood covers 9.15 square miles including a wide swath of the Santa Monica Mountains, giving it one of the lowest population densities in the City of Los Angeles. Practically that means long driveways, hillside access and sites where material has to be carried the last stretch.
Renters occupy about 59 percent of the housing stock, so a substantial share of the work is shared walkway, open stair and stacked balcony repair alongside the private hillside decks. Those surfaces stay in use while we repair them, so the job gets sequenced rather than closed off.
Hillside and flatland failures start in different places. On a slope it is the ledger and the post connections, hidden under the deck. On the flat it is the low corner, where water sits until the coating gives up at a seam and the plywood beneath goes soft.
Either way we open up and look before pricing. A recoat over sound framing is a small job. A recoat over wet framing is the same job done twice, and the second time costs more.

LADBS also holds the property records, worth checking on an older hillside deck where nobody is sure what was permitted originally. We file with LADBS and carry the work through inspection.

Yes. Sherman Oaks includes a portion of the Santa Monica Mountains as well as valley floor. On the slope the problem is where the water goes next. On the flat it is that it goes nowhere at all.
The Los Angeles Department of Building and Safety. Sherman Oaks is part of the City of Los Angeles, so plan review, permitting, inspection and enforcement all run through LADBS rather than a separate city counter.
It is normal here. This is one of the lowest density areas in the city, with a wide swath of mountain terrain, so we plan the material drop, the carry and the debris route into the estimate.
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.
Cost depends on the surface size, condition, and the coating system required. We provide a clear, itemized quote after a free on-site inspection, with no obligation and no pressure.
