Appliance and water heater leaks in Petaluma: what we see
In Petaluma's east-side subdivisions, water heaters in garages and laundry rooms next to living space are the usual culprits. In older west-side homes, a leak under a kitchen or laundry room often runs through the floor into the crawlspace.
The local picture
Where appliances sit in local homes. Housing type decides where leaks go and who they affect. Petaluma has older and historic homes on the west side near downtown and later subdivisions east of Highway 101.
Neighborhoods include the historic west side, downtown, and the east-side neighborhoods off North McDowell Boulevard. Conditions vary from street to street, so a provider should look at your specific home rather than assume.
What to do right now
- Turn off the appliance's water supply valve, or the main.
- For a water heater, turn off power or gas per the manufacturer's instructions, and the cold-water inlet.
- Photograph the appliance, the failed part and the wet areas.
- Move belongings, and pull back wet rugs.
- Call a plumber or appliance technician and a restoration provider.

How a provider handles it
A provider maps where water traveled, especially under cabinets, flooring and into walls, extracts it, removes what can't be dried, and dries the area with daily readings.
