Why Your Newly Installed Floor Makes a Click-Clack Sound When You Walk

The Planks Aren’t Locked Properly During Installation

Modern flooring, especially laminate and engineered wood, uses a click-lock system. If even one plank isn’t fitted perfectly, it moves slightly every time someone steps on it, creating that familiar click-clack sound.

Why this happens

• The plank wasn’t angled correctly before being pushed into place
• Dust or debris got stuck in the grooves
• The installer didn’t tap the planks firmly enough
• Some planks may have manufacturing defects
• The flooring expanded after installation and loosened the lock

When even one row is slightly misaligned, the issue spreads across the entire area. For long-term flooring durability, consider our Tiles/Stone Replacement services to ensure perfectly fitted surfaces.

How to detect it

Walk slowly over your floor and listen:

• Does the sound come from the joints between planks?
• Do the noises appear only along certain lines?

If yes, your lock system likely isn’t fully secure.

What solves it

Re-locking the affected planks or reinstalling a particular section usually fixes the issue. A skilled professional can do this without redoing the entire floor. The sooner it is corrected, the less long-term damage you risk.

Your Subfloor Isn’t Level – Even Slightly

Flooring is extremely sensitive to what lies underneath. Even a 2-3 mm dip or bump can create movement. And when your floating floor moves, it makes noise.

Typical signs of an uneven subfloor.

• A hollow sound when tapping certain spots
• The floor feels like it’s dipping or bouncing
• Clicking noises appear only in a few specific areas

Why unevenness causes clicking

Floating floors are designed to sit uniformly on a flat surface. When there’s a gap below:

• The plank bends slightly under pressure
• That movement causes friction
• Friction causes clicking, popping, or cracking noises

Over time, planks may separate or wear down from constant bending.

Common reasons for subfloor unevenness

• Cement screed wasn’t levelled
• High spots weren’t sanded down
• Old flooring residue wasn’t removed
• Moisture caused the subfloor to warp
• Natural settling of the building

Check out our Home Inspection services to detect subfloor issues before installation.

Fix

This usually involves lifting the affected area, levelling the subfloor using a compound, and reinstalling the flooring. It’s one of the most effective long-term solutions.

The Underlayment Isn’t Suitable for Your Flooring Type

Underlayment is one of the most important but most ignored layers. When the wrong material is used, or it’s installed incorrectly, your floor doesn’t get the support it needs – leading to noise.

What good underlayment should do

• Absorb sound
• Smooth out minor imperfections
• Reduce impact noise
• Prevent the floor from shifting
• Offer moisture protection

Common underlayment mistakes

• Using foam that’s too soft, causing the floor to sink with each step
• Using no underlayment at all
• Installing underlayment too thick for the chosen flooring
• Overlapping underlayment sheets, creating raised lines
• Using incompatible material for laminate, vinyl, or engineered wood

What the noise sounds like

A cushioned “pop” or a clicking sound when you walk – especially near the edges.

Fix

Replacing the underlayment in affected areas can dramatically reduce noise and extend the life of the flooring. This is often recommended when the noise is widespread. Learn more about our Marble Polishing services to combine aesthetic and functional floor upgrades.

Humidity & Temperature Changes Are Making the Planks Move

Flooring materials expand in heat and contract in cold. If your space has major humidity variations – AC, heaters, rainy months – your flooring reacts.

And when planks move, they make noise.

Typical symptoms

• Random clicking throughout the day
• Cracking sounds in the morning or at night
• Noise after switching on AC or fan
• Slight movement when you push planks with your foot

Why it happens

• Planks rub against each other as they expand
• Flooring presses against walls, creating tension
• Dry weather shrinks planks, causing gaps
• High moisture swells planks, lifting them

Fix

• Maintain stable indoor humidity
• Check if expansion gaps are blocked
• Remove trapped moisture if present
• Create additional space by adjusting edges

You can also explore our full house cleaning services to keep your floors clean and well-maintained, preventing dust or debris from worsening noises.

Humidity-related noises often improve once the environment is balanced. Explore Waterproofing solutions to protect your flooring from moisture-related issues.

The Installer Didn’t Leave Proper Expansion Gaps

Floating floors MUST have expansion gaps around the perimeter. If they don’t, the flooring becomes tight and pressure builds. That pressure is released as clicking, popping, or crackling sounds.

Why gaps matter

Floors naturally expand and contract. Without space, the boards get squeezed and push against the wall or skirting.

Signs your expansion gaps are missing

• The floor looks slightly lifted near the edges
• You hear louder popping in humid seasons
• Gaps appear between planks in the centre
• Noise worsens over time

Fix

Usually, this involves removing the skirting, cutting the flooring back to create proper expansion space, and reinstalling the skirting. It’s a straightforward fix but must be done before damage spreads. Our Wall Crack Filing service ensures expansion gaps and wall edges are maintained correctly.

Final Word

A freshly installed floor shouldn’t make you feel like you’re walking on bubble wrap. If you’re hearing clicks, pops, or crunches, it’s almost always due to installation errors, subfloor issues, underlayment problems, or humidity-related movement. The good news? These issues are fully fixable – and the sooner they’re addressed, the better your floor will perform.
