At the foot of the San Gabriels, where the water coming off the hills has to go somewhere.
Property at the base of a mountain range takes runoff that arrives quickly and in volume. Azusa is exactly that, at the foot of the San Gabriel Mountains in the San Gabriel Valley about 20 miles east of downtown Los Angeles, with the range along its northern edge. A deck that merely sheds water is not enough there. It has to move it somewhere deliberate, or the water works its way back into the structure and the slope behind it.
The northern city limit runs against the mountains themselves, with Irwindale to the west, Glendora and Citrus to the east, and Covina to the south. That upper end of town is the part where drainage design matters more than product selection, because water leaving a deck in the wrong direction on sloping ground becomes somebody's foundation problem later.
Of the 14,735 occupied housing units here, 53.3 percent are owner occupied and 46.7 percent are rented. It is close to an even split, and the work follows it. One week is a homeowner's rear deck and entry stair, the next is a shared walkway serving a floor of units.
What we look for first is where the water goes once it leaves the surface. Scuppers that discharge onto a slope, downspouts that dump at the base of a post, drains that were tiled over during a remodel: those cause more failures here than any coating ever has. We fix the path before we rebuild the surface.

Because Azusa sits at the foot of the San Gabriel Mountains and storm water arrives fast. A perfect membrane that sheds onto a slope has just moved the problem. We design where the water goes, then waterproof to suit.
The City of Azusa Building Division, which enforces state and local building codes here. We submit the package, meet the inspector, and close the permit out rather than leaving it open on your address.
Both. Azusa is close to an even owner-renter split across its 14,735 occupied units, so shared walkways and stairs are as routine for us here as single-family decks.
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.
