Slab leaks and aging pipe
Homes on slabs with copper lines underneath, and older homes with galvanized supply pipe, are common sources of hidden leaks that show up as warm floors, damp carpet or a rising water bill.

What La Jolla's homes say about water damage
In La Jolla, about two in three homes were built before 1980, and about one in six before 1960. Homes from those decades were usually plumbed with galvanized steel and cast iron. Both last a long time, but by now many are past the point where small, slow leaks start.
Rust-colored water, low pressure on upper floors and a musty smell near a wall are early signs worth acting on in a home this age.
Because homes here are built on slabs, a leak inside a wall or under the floor shows up late: a warm patch, a cupped board or a stain at the base of the wall.
About 30% of homes in La Jolla are in buildings with five or more units. In apartments and condos, water from one unit often reaches the unit below, so tell management or the HOA right away. The building's master policy and your own unit or renters policy may each cover a different part of the damage.
Hillside drainage, marine humidity and older plumbing all play a part in water damage here.

If water is coming in right now
- Stop the water. Close the valve at the fixture, or the main shutoff for the house.
- Make it safe. Cut power to wet rooms at the breaker only if you can reach the panel without standing in water.
- Protect what you can. Lift furniture off wet carpet with blocks or foil under the legs, and pull rugs off the floor so they don't stain or trap water.
- Photograph it, then get drying started. Photos come first for insurance; drying should begin the same day. Our first 24 hours guide has the full checklist.
Where the main shutoff usually is
San Diego-area homes usually have the main shutoff on the exterior wall near the front hose bib, with the meter in a box near the street.
If the water came from a toilet, a sewer line or outside, treat it as contaminated: see sewage backup cleanup or flood water cleanup.

Water damage questions from La Jolla
How quickly does water damage need to be dried in La Jolla?
Start within 24 to 48 hours; the EPA says materials dried in that window are much less likely to grow mold. Humid air around La Jolla shortens that window, so don't wait for a dry day.
Why do older homes in La Jolla have so many hidden leaks?
With about two in three homes in La Jolla built before 1980, a lot of original galvanized supply pipe and cast-iron drain line is still in service. Both corrode slowly and tend to leak at joints inside walls and under floors, where water spreads before anyone sees it.
