Squeaky and Uneven Floorboards
Why timber floorboards squeak or feel uneven underfoot, and how we sort it before new flooring goes down.
Squeaks and unevenness in timber floorboards are usually mechanical rather than structural — a board rubbing against a nail, or joists that have dried out and shifted slightly over the years. It's rarely urgent, but it's worth sorting before any new floor covering goes on top, because covering a problem doesn't fix it.
We come across this constantly when surveying older Kent properties ahead of a carpet, LVT or laminate fit, and it's a straightforward job to address at that stage.
Older Victorian and Edwardian properties in Kent often have floorboards running in different directions between rooms, laid in several phases over the decades, which is a common reason unevenness can be more noticeable at doorway thresholds where two different board runs meet.

How the problem shows up
- A distinct creak or squeak in the same spot when walked on
- Visible bounce or flex when standing on certain boards
- Boards that rock slightly, especially near the centre of a room
- A change in level between adjoining boards you can feel through socks
What's usually causing it
Squeaks happen when a board has come loose from its joist and rubs against a nail or against the neighbouring board as it flexes under weight. Unevenness is more often a sign of joists that have settled or bowed slightly, or boards that were never fully secured in the first place.
- Nails that have worked loose over years of foot traffic and humidity changes
- Joists shrinking or shifting slightly as timber dries out with age
- Boards cut or replaced at some point without matching thickness
- Sub-joist supports that have weakened or moved
How we check it on site
We walk the floor methodically, marking every point that creaks or moves, then lift a board where accessible to check joist condition and spacing. This tells us whether we're dealing with simple loose fixings or a wider levelling issue.
Fixing squeaks and levelling the floor
- Screwing boards down into joists to eliminate movement (quieter and more secure than re-nailing)
- Adding packers or shims under boards that have a slight gap to the joist
- Sanding or planing high spots for a flatter run before new flooring goes down
- Overlaying with plywood where the boards themselves are too uneven to correct individually
Why this matters before fitting a new floor
Laying LVT, laminate or engineered wood over a squeaky or uneven timber floor without addressing it first tends to transfer the same movement and noise up through the new surface, and can also cause clicking joints to work loose. Sorting the boards first gives the new floor a stable base to perform properly on.
Accessing joists from below where possible
Where there's a cellar, crawl space or accessible ceiling void below, fixing squeaks from underneath is often the least disruptive option, since packers, brackets or additional noggins can be added between joists without lifting a single board from above.
Where no underfloor access exists, we work from above, carefully lifting boards where needed and refitting them with screws rather than nails so the repair is more secure and easier to redo cleanly if the floor is ever lifted again in future.
Frequently asked questions
- Can squeaking floorboards be fixed without lifting the whole floor?
- Usually yes — most squeaks can be resolved by screwing the affected boards down from above or from below if there's underfloor access, without disturbing the rest of the room.
- Do I need to fix squeaky boards before new carpet or LVT is fitted?
- We'd strongly recommend it. A squeak under carpet is still a squeak, and under a hard floor like LVT it can also affect how securely the joints lock together.
- Is an uneven floor a sign of a structural problem?
- Not usually — most unevenness is cosmetic or fixing-related rather than structural. If we do see anything that looks structural during survey, we'll flag it and recommend the right specialist.
- How much disruption does fixing this cause?
- Minimal in most cases. Screwing down boards or adding packers is quick, dust-light work that's typically done as part of the same visit as your flooring fit.
