Foothill property below the San Gabriels, where a deck has to move water somewhere on purpose.
Claremont lies in the San Gabriel Valley at the foothills of the San Gabriel Mountains, and nearly 64 percent of its occupied homes are owner occupied. Foothill ground gives water momentum. A deck that only sheds water sends it straight to the base of a wall or into a slope, and the damage turns up somewhere other than the deck, which is why the diagnosis often takes longer than the repair.
We look at where the water is going before deciding what goes on top of the deck. Slope, drains, and the detail where the surface meets a wall or a post do more work than the coating brand ever will.
