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
Insufficient expansion gap
The floor presses against walls or fixed units.
Moisture ingress
Boards swell and distort.
Uneven subfloor
High spots can force joints upward.
Floor trapped by furniture or trim
Movement is restricted.
Symptom variations Match the exact movement, noise or finish defect. ⌄
- Raised ridge
- Boards spring underfoot
- Lifting near doorway
- Edges swollen
- Problem worse in humid weather
Quick checks Simple checks before lifting or drilling. ⌄
- Identify the flooring and subfloor type.
- Check for damp or leaks.
- Mark the exact high, low or loose area.
- Check hidden service zones.
- Choose repair materials for the substrate.
Step 1 — Check for moisture Check for hidden pipes, cables, moisture and structural movement before drilling or lifting flooring. ⌄
Look for leaks, damp edges or swollen joints.
Step 2 — Inspect perimeter gaps Check for hidden pipes, cables, moisture and structural movement before drilling or lifting flooring. ⌄
Remove trim locally and confirm the floor can expand.
Step 3 — Release trapped sections Check for hidden pipes, cables, moisture and structural movement before drilling or lifting flooring. ⌄
Correct tight edges or refit restrictive trim.
Common causes explained Why floor and skirting defects develop. ⌄
Laminate commonly lifts when it cannot expand, the subfloor is uneven, moisture enters the boards or heavy fittings trap the floor.
Advanced diagnostics Further checks for recurring or serious defects. ⌄
- Check subfloor moisture.
- Measure floor flatness.
- Inspect underlay condition.
- Check doorway transitions.
- Replace permanently swollen boards.
Parts and materials needed Common materials linked to this repair. ⌄
- Replacement laminate
- Spacers
- Underlay
- Threshold strip

When to call a professional Conditions that should end basic DIY work. ⌄
- The floor is structurally unstable.
- There is significant damp or mould.
- Hidden services may be at risk.
- Several tiles or boards are moving.
- The defect keeps returning after repair.
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.
