How Do I Clean up After a Washing Machine Leak?
Last updated October 25, 2026
The short answer
First Steps After the Leak
Turn off the washing machine and unplug it. Locate the shutoff valves behind the machine and close them to stop more water. If you live in Caldwell, keep the shutoff valve location written down for future reference.
Move wet items like rugs, shoes, and boxes out of the area. Use towels or a wet/dry vacuum to remove standing water. Open windows and run fans to start drying. Wear rubber gloves and boots if the water is dirty.

Dry Out the Affected Area
Drying is the most important part of cleanup. Use a dehumidifier to pull moisture from the air, especially in a closed room. Direct fans at the wet floor, baseboards, and lower walls. Keep the area ventilated for at least 48 hours.
Check the subfloor for moisture. If you have hardwood or laminate, water can warp boards or seep into the underlayment. Remove baseboards if they are wet. If the floor feels soft or spongy, the subfloor may be damaged and need replacement.
Clean and Disinfect Surfaces
Wash hard surfaces like tile or concrete with a mild detergent and water. Rinse with clean water and dry. For sealed surfaces, use a disinfectant to kill bacteria from the wash water. Follow the product label directions.
If the leak came from a supply hose, the water is likely clean. If it came from the washer drum, the water may contain detergent and dirt. That water can leave residue, so wipe down walls and floors thoroughly. Pay attention to cracks and crevices where moisture can hide.
Deal with Wet Drywall and Insulation
Wet drywall can sag, crumble, or grow mold within days. If the drywall is soft or stained, cut out the damaged section with a utility knife. Remove wet insulation as well. Allow the wall cavity to dry completely before installing new drywall.
If water traveled up the wall through capillary action, you may see a darker line above the water level. Cut the drywall at least 12 inches above that line. This is a job you can do yourself with basic tools, but for large areas, the pros can handle the removal and repair.
When to Call in the Pros
If the leak soaked into the subfloor, spread to other rooms, or reached the ceiling below, you may need professional help. Water can hide behind walls and under flooring. Local water damage pros have moisture meters and drying equipment to find hidden moisture.
They can also dry out the structure and prevent mold growth. If you notice a musty smell or see mold, contact a mold professional. Mold can cause health issues, so see a doctor if you feel unwell. Act quickly to prevent more damage.

How long does it take for mold to grow after a leak?
Mold can start growing within 24 to 48 hours in damp conditions. That is why it is important to dry everything quickly. Use fans and a dehumidifier to reduce moisture. If you see mold, clean it with detergent and water, or call a mold professional.
Can I use a regular vacuum to pick up water?
No, a regular vacuum is not designed for water and can be damaged or cause an electric shock. Use a wet/dry vacuum or a mop and bucket. If you must use towels, wring them out outside. Never use electrical appliances near standing water.
Will my insurance cover the cleanup?
Policies vary, and your insurer decides what is covered. Check your policy to see if water damage from a washing machine is included. If you file a claim, document the damage with photos and keep receipts for any items you replace. Ask your insurer about coverage for cleanup and repairs.
