Why water damage in Los Angeles is not what people expect

The dry climate misleads people, and it misleads them in a specific way. Outdoor humidity is low for much of the year, which leads homeowners to assume a wet building will simply dry on its own. Inside a closed wall cavity it does not: that space has its own microclimate, and once the framing in it is wet the air around it sits near saturation regardless of the weather on the patio.

The building stock is the second factor. A large share of the housing across these communities is post-war slab-on-grade, which means the supply lines run under concrete. A slab leak gives no visible drip. It shows as a warm patch on the floor, a water meter that moves with every tap closed, flooring lifting in a line, or baseboards swelling along one wall.

Older neighborhoods bring the opposite problem: raised foundations, original plaster, cast iron drains and galvanized supply pipe that fails from the inside out. Those materials are worth drying rather than removing, and that takes monitoring across days rather than a fixed schedule.

Then there is water that never touched a pipe. Irrigation running against a foundation delivers water underground and continuously. Hillside runoff during an atmospheric river arrives faster than any drain was sized for, and a garage cut into a slope is usually where it collects.

What all of it has in common is that the visible damage is the small part. We map the actual extent with meters and thermal imaging before anything is opened, because the alternative is cutting walls to look.
