Homes in San Jose and how they leak

Most of the city was built from the 1950s through the 1970s as single-story tract homes on slabs, with copper lines beneath. That includes Eichler homes, many of which have radiant heating pipes in the slab. Willow Glen and the Rose Garden have older homes on raised foundations.

Local issues that cause water damage

Slab and radiant-heat leaks

Aging copper under the slab, including radiant loops, develops leaks that show as warm or damp floors. See slab leak water damage.

Creek flooding

In February 2017, Coyote Creek flooded Rock Springs and nearby neighborhoods, forcing thousands to evacuate.

Winter roof leaks

Low-slope and flat roofs leak in atmospheric river storms.

Questions from San Jose homeowners

My Eichler's radiant heat is leaking. What are the options?

Plumbers can locate and repair the leak, but many owners abandon the in-slab system and install a different heating system. The wet flooring still needs drying.

Do I need flood insurance near Coyote Creek?

If you are in or near the floodplain, it is worth having. The 2017 flood surprised many residents without it.
