Nearly 90 percent of San Diego housing predates 2000, and original deck waterproofing does not last that long.
Roughly 57 percent of San Diego's housing stock is more than 40 years old, built before 1979, and nearly 90 percent of it was built prior to 2000. That is the single most useful fact about deck work in this city. Original waterproofing on a balcony or elevated walkway does not last four decades, so a very large share of the housing is either past the point of failure or approaching it.
The city sits on roughly 200 deep canyons and hills separating its mesas, which gives it genuinely hilly geography. Canyon lots mean decks reaching out over a grade, drainage with real consequences downslope, and access planned before a crew and materials arrive.
Occupied housing ran about 53 percent renter occupied in 2017, so alongside private decks there is substantial shared walkway, stair and balcony work on multi unit property. Those surfaces stay in service while we repair them, which means sequencing rather than closing a building.
On stock this age the original detailing is the story. Waterproofing that stops at the wall instead of turning up behind the finish, thresholds set flush with the deck, railing posts driven through the surface with nothing sealing them. Those were normal once and they are why the framing is wet now.
So we open up and find the entry point rather than pricing from the surface, replace what has rotted, correct the fall, and rebuild the metal where corrosion has taken section out of a stringer or an anchor.

Often it is. Around 57 percent of San Diego housing was built before 1979 and nearly 90 percent before 2000. Waterproofing does not run that long, so on stock this age we expect original detailing and check the framing rather than the surface.
It complicates access and drainage. The city sits on roughly 200 deep canyons and hills, so material handling, edge protection and where the runoff discharges all get worked out before the job starts.
Yes. Renters occupied about 53 percent of the city's housing as of 2017, so shared walkways, open stairs and stacked balconies are a large share of what we repair, staged so residents keep access.
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.
