Cleaning Up After a Water Heater Leak in Santa Clara

Shut It Down

1. Close the cold-water inlet valve above the tank, or the home's main shutoff.
2. For an electric tank, switch off its breaker. For gas, turn the control knob to off.
3. Keep away from hot water and wet electrical outlets.
4. Take pictures of the tank, its label and the wet area.

Why Older Santa Clara Homes See This

The City's history describes rapid growth after World War II, and the Census Bureau puts the median build year of Santa Clara's homes at 1975. Where a heater of that era sits in an interior closet or a utility room shared with laundry, rather than a garage with a floor drain, a failure has nowhere to go but into finished rooms.

Where the Water Travels

• under hardwood and laminate, where it can cup boards
• into the bottom plate and lower drywall of nearby walls
• beneath tile, toward the next room
• into the crawl space or slab edge, depending on the house

Thermal imaging and pin meters let us map it without opening walls blindly.

Our Cleanup

We extract standing water, remove wet baseboard and, only if readings call for it, the lower strip of drywall. Air movers and dehumidifiers dry the structure while we log readings daily. When it's dry, we repair drywall, paint and trim, and refinish or replace flooring as needed.

Replacing the Heater

That's a plumber's job, and in Santa Clara it needs a permit. The Building Division's simple permit covers like-for-like water heater replacement for single-family homes, duplexes and ADUs; condos, townhomes and homes in historic areas use the regular permit process.
