What Should I Do If I Find Water Under My Hardwood Floors?
Last updated October 25, 2026
The short answer
Stop the Water First
The first step is to stop the water from spreading. If a pipe or appliance is leaking, shut off the main water valve. If the water comes from outside, check for roof or window leaks. Move furniture and rugs off the wet area to prevent further staining and damage.
If you live in Detroit, keep your shutoff valve location written down. Knowing where it is saves time in an emergency. After stopping the source, remove any standing water with towels or a wet vacuum. Do not wait to see if the floor dries on its own. Wood absorbs water quickly and can swell or buckle.
Dry the Area Thoroughly
Use fans and dehumidifiers to dry the space. Open windows if weather allows. Lift the edges of the flooring carefully to let air circulate underneath. Do not use heat directly on the wood, as it can cause cracking. The goal is to remove moisture slowly.
If the water is extensive, the subfloor may also be wet. This can lead to mold and structural issues. A water damage inspection can reveal the full extent. The pros use moisture meters to check hidden dampness. This helps decide what can be saved and what must go.
- Turn off the water supply at the main valve
- Remove furniture and rugs from the wet area
- Use towels or a wet vacuum to extract standing water
- Run fans and a dehumidifier to speed drying
- Lift floor edges carefully to let air circulate
- Do not use high heat; let wood dry slowly
Assess the Damage
Look for signs of warping, cupping, or discoloration. Press on the boards to see if they feel soft or spongy. If the floor has been wet for long, mold may already be growing. A musty smell is a red flag. Document the damage with photos for your records.
The severity depends on how long the water sat and what kind of wood you have. Engineered hardwood may react differently than solid planks. A professional inspection can identify hidden issues. The pros can test moisture levels and check the subfloor's condition. This helps you decide between drying, repair, or replacement.
Know When to Remove Flooring
Sometimes the flooring cannot be saved. If the wood is severely swollen, split, or moldy, removal is the safest option. Water-damaged flooring removal involves taking out the affected boards and disposing of them properly. This prevents mold from spreading to other areas.
After removal, the subfloor needs to be checked. If it is wet or damaged, it may need repair. Subfloor and under-house water leak repair can address the source and the damage. The pros can dry and treat the area before new flooring goes down. This step is crucial to avoid future problems.
