Dishwasher Leak Restoration
Slow drip or sudden discharge from dishwasher supply line, drain hose, or door seal.
Dishwasher leaks are sneaky. They often start as slow drips that go undetected for weeks - water travels under the kitchen subfloor, into adjacent cabinets, and down to the basement before you see a stain. By the time the leak is visible, mold growth is usually already underway.
First-hour checklist
- 1
Shut off the dishwasher water supply (usually a small valve under the kitchen sink).
- 2
Pull the dishwasher out from under the counter to expose the floor below.
- 3
Remove the kick plate to inspect the cabinet base.
- 4
Check the basement ceiling directly below the dishwasher for water staining.
- 5
Photograph everything you find - cabinets, floor, ceiling below.
- 6

How Catalyst handles dishwasher
- Step 1
Source confirmation + extent mapping
We use moisture meters and thermal imaging to map how far the water traveled - often into wall cavities, adjacent cabinets, and the floor below.
- Step 2
Selective demolition
Cabinet bases, lower drywall, kitchen flooring (if engineered or laminate), and any wet subfloor come out.
- Step 3
Mold assessment
Most dishwasher leaks have been active long enough to start mold growth. We document any visible mold and contain remediation if needed.
- Step 4
Drying with full containment
Standard drying setup, with containment if mold remediation is part of scope.
- Step 5
Final clearance
IICRC dry standard verified before reconstruction begins.
Dishwasher leaks are typically covered if discovered promptly. A leak that's been going for weeks or months may face "gradual loss" exclusions on the mold portion of the claim. We document the timeline carefully - "we just discovered this" framing is critical for coverage.
All carrier-specific claim guidanceDishwasher Leak Restoration — FAQ
Watch for warped flooring at the dishwasher base, soft cabinet kick plates, water stains in the basement ceiling directly below the kitchen, or musty odors from the cabinet interior. Many dishwasher leaks go undetected for months.
No - the appliance is maintenance. The water damage from the leak IS covered, including cabinet replacement, flooring, and any structural drying. Mold remediation may be limited if the leak is determined to have been gradual.
For a small, recent leak yes. For anything more than 24-48 hours of leakage, the issue is usually the wet subfloor + wall cavity behind the dishwasher. Skipping proper drying lets mold establish behind the new cabinet.
