Pomona Valley homes below the San Gabriel foothills, seven in ten of them owner occupied.
There are 12,218 housing units in La Verne at 1,450 per square mile, 96.9 percent occupied, and 71.1 percent of those are owner occupied. This is predominantly homeowner work. The city lies about 30 miles east of Los Angeles in the Pomona Valley, below the foothills of the San Gabriel Mountains and Angeles National Forest.
Foothill position means two things at once for a deck. Water arrives from above with momentum during storms, and the rest of the year the inland heat cycles the surface daily, opening up the edges and penetrations that the water will later exploit. Most failures we open up here started in summer and only announced themselves in winter.
Low density means bigger structures. Decks that wrap a corner of the house, stairs running from a raised entry down to a driveway, balconies over living space with a door onto them. More perimeter and more penetrations is more places for a surface to end, and every place it ends is a place it can fail.
The door threshold is the one homeowners never suspect. If there is no pan flashing under the sill and the deck does not fall away from the door, every storm pushes water into the framing at the exact point where the floor of the house begins. That leak shows up as a soft spot inside long before anything drips.
Our sequence does not vary much: probe the deck, read moisture at the wall line and post bases, take a test cut if the readings say so, then price what is actually there. If the plywood is sound it is a tear-off and rebuild of the details. If it is not, you get told that before you spend money on a coating.

It did not fail in one storm. Inland heat cycles the surface every day and works the edges, posts and wall junction loose over seasons. The storm is simply the first event large enough to exploit what was already open.
Almost certainly. That is the classic threshold failure. With no pan flashing under the sill and no fall away from the door, water is driven into the framing right where the floor of the house starts, and the damage moves inward from there.
We do. The La Verne Building and Safety Division checks the plans, issues the permit and inspects the work, and we carry all three so the permit closes out rather than sitting open against your property.
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.
