A squeaky floorboard is one of the most common noises in older UK homes, caused by boards rubbing against joists or each other as they flex underfoot. Most squeaks can be fixed without lifting the floor, using one of a few reliable techniques.
How Do You Fix a Squeaky Floorboard?
To fix a squeaky floorboard, locate the exact spot causing the noise, then secure the board to the joist beneath it using screws driven at an angle, or fill small gaps between boards with a lubricant such as talcum powder or a specialist floor lubricant. Which fix works best depends on whether the squeak comes from movement against the joist or friction between two boards.
What Causes a Squeaky Floorboard?
Floorboards squeak when they move slightly against a joist, a neighbouring board, or a loose nail, creating friction that produces a creaking sound. This is common in older homes where timber has dried out and shrunk over time, loosening the original fixings and leaving small gaps that allow movement underfoot.
What You Will Need
- A stud finder, to locate joists beneath carpet if needed
- Wood screws, longer than the original fixing nails
- A drill and screwdriver bit
- Talcum powder or a specialist floor lubricant, for gap-related squeaks
- Wood glue and shims, for boards with a persistent gap
How to Fix a Squeaky Floorboard: Step by Step
1. Locate the Exact Squeak
Walk slowly across the floor, pressing down with your weight at different points until you pinpoint exactly where the squeak occurs. Mark the spot, since it is often smaller and more precise than it feels underfoot.
2. Identify the Cause
Press down firmly on the board. If it flexes and squeaks against the joist beneath, the fix is securing the board more firmly. If two boards rub against each other along their edge, a lubricant-based fix is usually more effective.
3. Secure the Board to the Joist
Using a stud finder if the floor is carpeted, locate the nearest joist. Drive a wood screw through the board and into the joist at a slight angle, which pulls the board down more securely than a straight vertical screw. Countersink the screw head so it sits flush or slightly below the surface.
4. Treat Gaps Between Boards
For squeaks caused by boards rubbing together rather than against a joist, work talcum powder or a specialist floor lubricant into the gap between boards, then walk over the area to help it settle in and reduce the friction causing the noise.
5. Use Shims for Larger Gaps
If a gap between a board and joist is large enough to see, apply a small amount of wood glue to a thin wooden shim and gently tap it into the gap until snug, then trim away any excess protruding above the floor.
6. Test the Fix
Walk over the repaired area several times to check the squeak has gone. If it persists, the board may need a second screw at a slightly different point along its length.
Fixing Squeaks Under Carpet
You do not need to lift carpet to fix most squeaks. Specialist squeak-repair kits use a guided screw system that drives through the carpet and subfloor into the joist below, then snaps off cleanly beneath the carpet surface, leaving no visible fixing once removed.

Frequently Asked Questions
Can I fix a squeaky floorboard without lifting it?
Yes, in most cases. Screwing the board down to the joist at an angle, or treating gaps with a lubricant, resolves most squeaks without needing to remove the board itself.
What is the best lubricant for a squeaky floorboard?
Talcum powder is a simple, effective option for gap-related squeaks, and specialist floor lubricants designed for this purpose are also widely available and slightly longer-lasting.
Can I fix a squeaky floorboard under carpet?
Yes. Specialist squeak-repair kits allow you to screw through the carpet directly into the joist below without needing to lift the carpet at all.
Why does my floor squeak more in winter?
Wood naturally contracts slightly in cold, dry conditions, which can widen small gaps between boards and joists, temporarily making existing squeaks more noticeable.
Is a squeaky floorboard a structural problem?
Usually not. Most squeaks are simply due to natural movement and minor gaps that develop over time, though widespread or worsening squeaks across a large area are worth having checked, since they can occasionally point to joist movement or subfloor issues.
If squeaking is widespread across a large area of flooring, or accompanied by visible sagging, it is worth having a builder assess the subfloor before attempting a DIY fix.
