Hillside decks between two mountain ranges, on lots where the oak trees have legal protection.
Agoura Hills sits in the eastern Conejo Valley between the Simi Hills and the Santa Monica Mountains. Decks here are usually doing structural work as well as living space, stepping down a slope or reaching out over one, which puts the waterproof layer under constant movement and makes the drainage detail more important than the coating itself.
There is a local constraint worth knowing before a crew shows up. The city protects any oak with a trunk two inches across or larger, and the protected zone runs to the edge of the canopy plus another five feet. That footprint often covers exactly where you would want to stage material or set up access for a deck rebuild. We plan the approach around it rather than finding out mid job.
Three quarters of occupied homes here are owner occupied, so most of what we do is single family: elevated decks, entry stairs, and balconies that have started letting water into the wall behind them.
