How to Dry Wet Laundry Room

Last updated October 25, 2026

The short answer

Stop the Water Source

First, shut off the water supply to the washing machine and any other fixtures in the laundry room. Look for the shutoff valve on the wall behind the washer or on the supply hoses. If you cannot find it, turn off the main water valve for your home. This stops more water from entering and makes the drying process easier.

Next, turn off power to the room at the circuit breaker, especially if water may have reached outlets or the floor. Water and electricity are a dangerous mix, so do not touch anything wet until power is off. If you are unsure about safety, wait for a professional electrician to check the area before you proceed.

Remove Standing Water

Use towels, a mop, or a wet-dry vacuum to soak up standing water from the floor. Work from the edges toward the center to avoid spreading the water. Wring out towels into a bucket or drain outside. The faster you remove the water, the less time it has to soak into walls, baseboards, or flooring.

If you have a wet-dry vacuum, use it to extract water from carpet, tile grout, or cracks in the floor. Pay attention to corners and under appliances. Move the washer and dryer if possible to check for trapped water. Even a small amount left behind can lead to mold or mildew growth.

  • Use a wet-dry vacuum for fast water pickup
  • Lift rugs or mats and take them outside to dry
  • Wipe down appliance surfaces with a dry cloth
  • Check under the washer and dryer for hidden puddles
  • Squeeze water out of sponges or towels into a bucket
  • Open the washer door and leave it ajar to air out

Increase Airflow and Ventilation

Open windows and doors in the laundry room to let fresh air circulate. Place fans strategically to blow air across wet surfaces and toward the open doorway. Aim fans at the floor and lower walls, as moisture tends to settle there. If you have a ceiling fan, turn it on to keep air moving upward.

Use a dehumidifier to pull moisture from the air. This is especially helpful in humid climates, like the one in Rowlett, Texas. A dehumidifier reduces the humidity level, which speeds up drying and helps prevent musty odors. Empty the water collection tank regularly, or connect a hose to a drain if possible.

Dry Surfaces and Materials

Wipe down all hard surfaces, including walls, cabinets, and countertops, with a dry cloth. Use a mop or sponge to absorb water from tile or vinyl floors. For baseboards and door frames, use a towel to press out moisture. Check behind the washer and dryer for dampness that could seep into drywall.

If water soaked into drywall, insulation, or flooring, those materials may need professional attention. Wet drywall can swell and crumble, and wet insulation loses its effectiveness. A water damage inspection can determine the extent of the damage. Local water damage pros can remove and replace wet materials as needed.

  • Wipe down walls, cabinets, and shelves
  • Press towels into baseboards to absorb moisture
  • Lift the washer and dryer to dry the floor beneath
  • Check the ceiling for water stains or sagging spots
  • Move wet cardboard boxes or paper items to a dry spot
  • Use a moisture meter to test hidden damp areas

Prevent Mold and Musty Odors

After the area is dry, keep the room well-ventilated for a few days to prevent lingering moisture. Run a fan or dehumidifier on a low setting to maintain low humidity. Look for any signs of mold, such as dark spots or a musty smell. If you notice mold, clean it with a mild detergent and water, or contact a mold professional for larger areas.

If the laundry room has a floor drain, pour a bucket of clean water down it to flush any debris. Check the washing machine hoses for cracks or loose connections, and replace them if needed. Consider keeping a written note of your shutoff valve location for future emergencies. If the damage is extensive, a professional dry-out service can help ensure everything is fully dried.

Frequently asked questions

How long does it take to dry a wet laundry room?

The time depends on how much water is present and the drying methods you use. With fans and a dehumidifier, a small spill might dry in a day or two. If water soaked into walls or flooring, it can take several days to a week. Professional drying equipment can speed up the process.

Can I dry wet laundry room carpet myself?

Yes, if the carpet is only lightly damp. Use a wet-dry vacuum to extract water, then place fans and a dehumidifier to dry it completely. If the carpet was heavily soaked or the padding is wet, it may need to be removed and replaced. Check for mold growth within 24 to 48 hours.

Should I call a professional for a flooded laundry room?

If water spread beyond the floor or soaked into walls, insulation, or the ceiling, professional help is wise. The pros have industrial fans, dehumidifiers, and moisture meters to dry hidden areas. They can also remove and replace wet drywall or flooring. For minor spills, you can handle it yourself.
