Deck Waterproofing in Duarte
Durable waterproof coatings that protect walking decks, roof decks, and balconies from water intrusion.

Duarte is bounded to the north by the San Gabriel Mountains, with Bradbury and Monrovia to the west and Irwindale and Azusa on the other sides. Foothill property means slope, and slope means the water coming off a deck has somewhere to go and gets there fast. Drainage detail matters more here than the brand of coating does.
About two thirds of occupied homes in Duarte are owner occupied, so most of what we do here is homeowner work: a back deck over living space, an entry stair that has gone soft, a balcony that has started staining the stucco below it.

Learn more →Duarte does not do plan check in house. Building and plan check services are provided under a contract with Charles Abbott Associates, managed by the city's Community Development Director. Worth budgeting for as well: the city collects a construction and demolition deposit and refunds it only on completion with verification of 65 percent waste diversion, so debris handling needs to be documented rather than just hauled away.
