Appliance Leak Water Damage in Richardson, TX
Ice-maker lines, washing machine hoses, dishwashers and AC drain lines cause some of the most expensive water damage, because they often leak out of sight for weeks. Shut off the appliance’s water supply and call (972) 947-2040.
Shut it off
Where each appliance shuts off
| Appliance | Where the shutoff usually is |
|---|---|
| Refrigerator / ice maker | Small valve behind the fridge or under the kitchen sink |
| Washing machine | Hot and cold valves on the wall behind the washer |
| Dishwasher | Valve under the kitchen sink |
| AC condensate overflow | Turn the system off at the thermostat |
| Can’t find it? | Shut off the main water valve to the house |
Why they cost more
Why hidden appliance leaks get expensive
A burst hose is loud and obvious. A pinhole in a refrigerator line or a slow dishwasher leak isn’t. Water spreads under cabinets, into the subfloor and along the bottoms of walls before anyone sees a stain.
Some of the largest DFW water damage invoices homeowners have shared publicly, in the $10,000 to $14,000+ range, came from leaks like these that ran unnoticed. Insurers also look harder at slow leaks, since gradual damage is often excluded.
Prevention
How to prevent appliance leaks
- Replace rubber washing machine hoses with steel-reinforced ones; insurers recommend replacing supply hoses every three to five years, according to Consumers’ Checkbook.
- Check behind the fridge and under the sink a few times a year.
- Have the AC condensate line flushed with regular HVAC service, and check the attic drain pan for rust.
- Consider a leak detector under the sink, fridge and washer, or an automatic shutoff valve.
- Turn off the washer supply valves when you travel.
Room by room
Signs of a hidden appliance leak
Slow appliance leaks rarely show up as a puddle. They show up as small changes in the floor, walls or cabinets nearby. Check these spots in your home:
- Kitchen, by the dishwasher: flooring that is lifting, cupped or soft next to the door, or vinyl and laminate seams that have opened up.
- Under the kitchen sink: a swollen or stained cabinet floor, or a musty smell when you open the doors.
- Behind the refrigerator: darkened grout, a stained baseboard or a soft spot in the floor where the ice maker line runs.
- Laundry room: stains or peeling paint on the baseboard behind the washer, or a stain on the ceiling below an upstairs laundry room.
- AC closet or attic: water around the indoor unit, a rusty drain pan, or a ceiling stain below an attic air handler. North Texas’s long cooling season keeps condensate lines busy for months.
If you find any of these, shut off the appliance’s water supply and stop using it. We don’t repair appliances or AC systems. For the wet floors, cabinets and walls, call (972) 947-2040 and we’ll connect you with an independent provider who can check the moisture and dry it out.

Cleanup
What cleanup involves
Extraction, removal of wet toe-kicks, baseboards and flooring where water got underneath, and structural drying with daily readings. Cabinets sometimes need to be pulled to dry the wall behind them. Floating floors and hardwood floors need special attention.

FAQ
Appliance leak FAQs
How often should I replace washing machine hoses?
Consumers’ Checkbook reports that insurance companies recommend replacing washer supply hoses every three to five years, and suggests heavy-duty, steel-reinforced hoses. Check them for bulges, cracks and rust at the fittings whenever you move the machine.
How do I know if my refrigerator water line is leaking?
Look for water under or behind the fridge, warped or darkened flooring nearby, a musty smell, or a water bill that rose without explanation. Ice-maker lines often leak slowly behind the fridge for weeks before anyone notices.
Can an AC unit cause water damage?
Yes. Air conditioners produce condensation that drains through a condensate line. If that line clogs or the drain pan rusts, water can overflow into ceilings below an attic unit or into closets and floors around an indoor unit.
Will insurance pay for appliance leak damage?
Sudden leaks, like a hose that bursts, are commonly covered. Slow leaks that went on for weeks are often excluded as gradual damage, which is why hidden ice-maker and dishwasher leaks can be expensive.
Should I call an appliance repair tech or a water damage company?
Often both, for different jobs. The repair tech or plumber fixes the hose, valve or appliance. A water damage company dries the floor, cabinets and walls the water reached. If water has soaked into flooring or drywall, call for the water damage the same day, because drying works best when it starts early.
Is a slow dishwasher leak under the floor serious?
It can be. A slow leak can soak the subfloor and the cabinet base for weeks before the surface floor shows it, and wood and particleboard that stay wet can warp or grow mold. The EPA advises drying wet materials within 24 to 48 hours to help prevent mold growth, so have the area checked with a moisture meter instead of waiting for it to dry on its own.
