Deck Waterproofing in San Dimas
Long-lasting waterproof coating systems that keep walking decks, roof decks, and balconies protected from water intrusion.
Deck Waterproofing detailsFoothill suburb well east of the city, nearly three quarters of it owner occupied.
Takes about 30 seconds. No obligation, no pressure.
People stay in San Dimas houses, and that changes what they want from a deck repair. Nobody here is looking for something that gets them through to a sale. The city runs along the foothills of the San Gabriel Mountains about 28 miles east and northeast of downtown Los Angeles, and 72.8 percent of its 12,030 occupied homes are owner occupied.
Foothill ground means water arriving with momentum, so the repair has to move it somewhere deliberate rather than simply off the edge. Get that wrong and the water ends up at the foundation or in the slope, and the deck was never really the problem.
What we open up on these houses is usually predictable. The ledger where the deck attaches to the building has been taking water behind a piece of flashing that was never lapped correctly. The posts have been sitting on a surface that ponds. The stair landings, which sit lower than everything around them, have been wet for years and nobody could see it.
Being inland, the destruction is seasonal in a way owners rarely connect. Long dry months of daily expansion and contraction work every edge and penetration loose. Then the first serious storm exploits all of them at once, and the storm gets the blame.
Where a stair run has corroded or rotted past honest repair, we fabricate and set new iron or precast stairs rather than selling another season of patching on a structure people use every day.

A local crew looks at the actual deck, and the quote comes back itemized.
San Dimas sits along the foothills of the San Gabriel Mountains, so water arrives with momentum. A deck that only sheds it moves the problem to the foundation or the slope. We route it deliberately, then waterproof to match.
In this city usually yes. With 72.8 percent of occupied housing units owner occupied out of 12,506 total, most clients here intend to keep living with the work, so tear off and correction beats another coat over a failed one.
