FLOORS & SKIRTING

Floorboard Squeaking

Floorboards usually squeak because they move against joists, neighbouring boards, fixings or hidden pipework.

▤
!

Check for hidden pipes, cables, damp and structural movement before drilling, lifting or cutting flooring

Wear suitable eye and dust protection. Stop if the floor is unstable, heavily damp, contains suspect asbestos materials or shows significant movement.

MOST LIKELY CAUSES

Start with these

Loose fixing The board moves slightly under load.
Board rubbing Edges may rub against neighbouring boards.
Joist movement The board may not be tightly supported.
Hidden pipe contact A pipe beneath may rub against timber.

? Frequently asked questions Common floor and skirting questions. ⌄

Can I screw straight through a squeaking board?

Only after checking joist position and hidden pipes or cables.

Should I fill gaps under skirting with rigid filler?

Usually not. Flexible filler or trim copes better with movement.
