A failed water heater can dump 40+ gallons — usually where you'll notice too late.
Water heaters fail. It's usually a matter of when, not if — most last 8 to 12 years, and coastal salt air can shorten that. When one lets go, it can release its whole tank plus whatever the supply keeps feeding it, flooding a garage, closet, or attic and soaking into everything nearby.
We clean up the water fast, dry the affected area properly, and help prevent the mold that loves a warm, damp garage. If the heater sits in an attic or closet, we also check the ceiling and walls below for hidden damage.
