How to Dry Out a Laundry Room After a Leak?

Last updated October 25, 2026

The short answer

Stop the Water and Stay Safe

First, shut off the water supply to the washing machine or the main valve if you cannot find the leak. If water is near electrical outlets or appliances, turn off the circuit breaker for that room before touching anything. Wear rubber boots and gloves if water is deep.

Move wet items like rugs, cardboard boxes, or laundry baskets out of the room. If the leak is from a pipe or appliance, check for sagging ceilings or wet walls nearby. See a doctor if you feel unwell from any odors, and call a plumber if the source is not obvious.

Remove Standing Water Quickly

Use a wet vacuum to pull up water from the floor, or soak it up with old towels and wring them into a bucket. Pay attention to corners, under the washing machine, and along baseboards where water hides. The faster you remove standing water, the less it soaks into wood and drywall.

If the water is clean from a supply line, you can handle it yourself. If it came from a drain or sewer, treat it as contaminated and avoid skin contact. Open windows and doors to let fresh air move through the room while you work.

Wear gloves and boots
Use a wet vacuum for large puddles
Wring towels into a bucket
Check under appliances and cabinets
Open windows for airflow

Dry Surfaces and Materials

Set up fans to blow across wet floors and walls, and run a dehumidifier to pull moisture from the air. Aim fans at the base of walls and under cabinets where air does not naturally move. If you have a wet vacuum, use it to remove water from low spots.

Check for Hidden Moisture

Moisture can sneak into wall cavities, under flooring, and behind appliances. Use a moisture meter if you have one, or press a hand against surfaces to feel for dampness. Look for discoloration or bubbling paint on walls and ceilings, which signals trapped water.

If the leak came from a washing machine hose, inspect the hose for cracks or loose connections. For leaks from pipes, you may need to cut into drywall to let the area dry. If you suspect water is trapped in walls or under the floor, a water damage inspection can find the full extent.

Watch for musty smells

Prevent Mold and Future Leaks

Mold can start growing within a day or two on wet surfaces. Clean and dry everything thoroughly, and consider using a disinfectant on hard surfaces. If you see mold or smell mildew, a mold professional can assess the situation and advise on safe removal.

After the room is dry, check the washing machine hoses for wear and replace them if they are old. Keep the shutoff valve location written down so you can find it quickly in an emergency. If the leak came from a pipe or appliance, repair the source before using the room again.

Frequently asked questions

How long does it take to dry a laundry room?

It depends on the amount of water, the materials, and airflow. With fans and a dehumidifier, surfaces may dry in a few days, but walls and subfloors can take longer. Keep air moving until all surfaces feel dry to the touch.

Can I use a regular fan to dry the room?

Yes, a regular fan helps, but a high-velocity fan moves more air. Place it to blow across wet areas and change its position periodically. A dehumidifier also helps, especially in humid weather.

Should I call a professional for a laundry room leak?

If the leak is small and you can dry the room quickly, you may handle it yourself. For large leaks, hidden moisture, or if water reached electrical systems, local water damage pros can do the drying work. They have equipment to reach trapped water.
