Pasadena gets about six inches more rain a year than Los Angeles. Your deck notices the difference.
Pasadena averages 20.08 inches of rain a year, roughly six inches more than nearby Los Angeles, because the San Gabriel Mountains force air upward and wring more precipitation out of it. That orographic effect is the single most useful fact about waterproofing here. A deck detail that survives in the flats of Los Angeles is being asked to do measurably more work in Pasadena, every single year.
It shows up as a shorter service life on the same coating, and as failures that start at edges and penetrations rather than in the field of the deck. More water, arriving harder, finds the weak detail sooner.
The city has 61,643 housing units at 2,684 per square mile, 94.1 percent of them occupied, and 57.1 percent of the occupied ones are rented. So the work spans homeowner decks and a substantial volume of multi unit walkway, stair and balcony repair, much of it on older buildings that have been recoated more than once.
Extra annual rainfall also changes what drainage capacity means. A drain and an overflow that would be adequate in the basin can be undersized here, and once water backs above the flange the deck is a pond with a crack in it. We look at outlet sizing and overflow before we look at coatings.
On older Pasadena buildings the other recurring find is layering. Successive coats applied over failing ones move independently and delaminate at the interface, so a surface can look freshly done and be holding no water at all. Test cuts settle it quickly.

About six inches a year more, 20.08 inches on average, because the San Gabriel Mountains force air upward and squeeze more precipitation out of it. That extra load is why the same coating on the same detail has a shorter life here than it does in the basin.
The city has launched a Fee Waiver and Refund Program for eligible properties under Bulletin 21. Eligibility is set by the city and tied to the property, so it is worth confirming your address qualifies before filing.
Usually because the recoat went over a system that had already let go. Layers that do not bond move separately and split at the interface, so the new material fails early no matter how good it was. A test cut shows what is holding and what is not.
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.
Most residential decks, balconies, and stairs take about a week from start to finish, depending on prep, repairs, and weather. We give you a firm timeline before work begins.
