The short answer
Dry the Area First
Before you do anything, make sure the floor is completely dry. Water can soak into the subfloor and joists, causing them to swell and shift. Use fans and a dehumidifier to pull moisture out of the wood. This can take several days, depending on how bad the leak was.
Check for any remaining moisture with a moisture meter if you have one. If the wood still feels damp, keep drying. Attempting to fix a squeak on a wet floor will not hold. The wood will continue to move as it dries, and the squeak may come back.
Find the Source of the Squeak
Walk slowly across the floor and listen for the squeak. Mark the spot with a piece of chalk or tape. The squeak is often caused by the floorboard rubbing against a nail or the subfloor. You might need to check underneath the floor, if you have access, to see the joists.
If you can access the basement or crawlspace, have someone walk on the floor while you look underneath. You may see gaps between the subfloor and the joists. Those gaps let the floor flex and squeak. Knowing the exact spot helps you target your fix.
- Listen for the squeak and mark it with tape
- Check under the floor for gaps or loose nails
- Look for water stains or warping on the subfloor
- Use a stud finder to locate joists from above
- Test the floor for movement by pressing down
Secure the Floor to the Joists
Once you know where the squeak is, you can secure the floorboard to the joist. Use screws that are long enough to go through the flooring and into the joist. A screw is often better than a nail because it pulls the wood tight and is less likely to loosen over time.
Drill a pilot hole first to avoid splitting the wood. Then drive the screw in, but do not overtighten. You want to pull the floor down snug, not strip the hole. If the screw sinks in too easily, the subfloor may be too damaged to hold, and you might need a larger repair.
When to Consider Replacing the Floor
If the subfloor is soft, rotted, or has large gaps, screws may not be enough. Water damage can weaken the wood so that it no longer provides a solid base. In that case, you may need to remove the damaged flooring and replace the subfloor. This is a bigger job that requires cutting out sections and installing new plywood.
If you are unsure about the condition of your floor, a water damage inspection can help. The pros can assess the extent of the damage and recommend the right approach. They can also handle the replacement if needed, ensuring the new floor is level and secure.
- Soft or crumbly subfloor means replacement is needed
- Large gaps between subfloor and joists may require shimming
- Persistent squeaks after screwing may indicate deeper damage
- If mold is present, take precautions and consider professional help
Prevent Future Squeaks
After fixing the squeak, take steps to prevent future water damage. Check for leaks in appliances, pipes, and the roof. Fix any issues quickly to avoid moisture reaching the floor again. Keep the area well-ventilated to reduce humidity.
If you live in Layton, keep your shutoff valve location written down. Knowing how to stop the water quickly can limit damage. Regular inspections can catch small problems before they become big ones. If you notice any new squeaks, address them early to avoid more extensive repairs.

Can I use construction adhesive to fix a squeaky floor?
Adhesive can work if the squeak is between the subfloor and the finish floor. However, it is hard to apply without pulling up the flooring. Screws are usually simpler and more effective. If you use adhesive, make sure the surfaces are clean and dry.
How do I know if the subfloor is damaged?
Look for soft spots, discoloration, or a musty smell. Press on the floor with a screwdriver; if it sinks in, the wood is weakened. If you have access underneath, check for sagging or rot. A water damage inspection can give you a clearer answer.
Should I hire a pro for a squeaky floor after a leak?
If the squeak is minor and the floor is dry, you can try fixing it yourself. But if you suspect subfloor damage or the squeak persists, a pro can help. They can assess the extent of the water damage and recommend the right repair. Policies vary, and your insurer decides what is covered.
