The biggest city in the San Gabriel Valley, with summers that quietly take decks apart.
Pomona is the most populous city in the San Gabriel Valley, with 43,352 housing units and occupied housing split close to evenly between owners and renters. Its climate is hot and dry through summer and mild and damp through winter, with a great deal of sunshine year round.
That sunshine is the problem. Constant UV and daily thermal movement break down a coating from above while working its edges loose from below, and none of it is visible from the ground. The damp winter then arrives at a surface that has spent six months being prepared to fail. Most of the decks we open up here did not fail in a storm, they failed in July and only reported it in January.
