Appliance and water heater leaks in Mill Valley, CA

Water heaters, washing machines, dishwashers and refrigerator ice makers cause a large share of indoor water damage, often slowly and out of sight. Here's what that looks like in Mill Valley, what to do, and how to get connected with an independent, licensed local provider.

Appliance and water heater leaks in Mill Valley: what we see

In Mill Valley's multi-level hillside homes, appliances on upper floors, like laundry rooms, dishwashers and refrigerator ice makers, can leak into rooms below. Water heaters in crawlspaces or under-house closets can leak unnoticed.

The local picture

Where appliances sit in local homes. Housing type decides where leaks go and who they affect. Mill Valley has older cottages and craftsman homes on steep lots, many over crawlspaces, mid-century homes in Strawberry and Tamalpais Valley, and large hillside homes, often with decks, stairs and long drainage runs.

Conditions vary a lot from street to street in Mill Valley, so a provider should assess your specific home.

What to do right now

  1. Turn off the appliance's water supply valve, or the main.
  2. For a water heater, turn off power or gas per the manufacturer's instructions, and the cold-water inlet.
  3. Photograph the appliance, the failed part and the wet areas.
  4. Move belongings, and pull back wet rugs.
  5. Call a plumber or appliance technician and a restoration provider.

Mill Valley checklist

  • If your water heater is under the house, check it whenever you check the crawlspace.
  • Put drain pans and leak sensors under the water heater and washer.
  • Replace rubber supply hoses with braided lines.
  • Check the water heater's age and look for rust at the base.
  • Know where each appliance's shutoff valve is.

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.

Frequently asked questions

Can my water heater be in the crawlspace?

Some older homes have them there. Make sure it's inspected and that leaks would be noticed.

Why check under cabinets?

Water from dishwashers and sinks often spreads under cabinets, where it can't dry on its own.
