Laminate flooring that creaks underfoot is one of the most common complaints homeowners face. That persistent squeaking or groaning every time you walk across the room can be frustrating, but the good news is that most creaking issues have straightforward causes and fixable solutions.
This guide explains why laminate floors creak, how to diagnose and fix the problem, and what steps you can take to prevent it from happening in the first place.
What Causes Laminate Flooring to Creak?
Laminate flooring creaks when there is movement between the planks, between the laminate and the subfloor, or within the subfloor structure itself. Understanding the specific cause helps you choose the most effective fix.
Improper Installation
Installation errors are the most common reason for creaking laminate floors. These include:
- Insufficient expansion gaps around the room’s perimeter, which causes the floor to press against walls and buckle slightly
- Poor plank alignment during click-lock assembly, leaving joints that are not fully engaged
- Skipping acclimatisation before fitting, meaning the planks expand or contract after installation
- Incorrect or missing underlay that fails to cushion the floor properly against the subfloor
Even a small mistake during installation can create movement points that produce noise over time. If the creaking started soon after installation, this is likely the culprit.
Subfloor Problems
An uneven or damaged subfloor is the second most common cause. Issues include:
- Dips and high spots that create voids beneath the laminate, allowing it to flex when walked on
- Loose subfloor boards (in timber subfloors) that move independently of the joists
- Concrete subfloors with ridges from poor screeding or leftover adhesive from previous flooring
- Structural settling that has caused the subfloor to shift since the laminate was installed
Industry guidelines recommend that subfloors should be level to within 3mm over a 1-metre span before laminate is laid. Anything beyond this tolerance increases the risk of creaking.
Humidity and Moisture Changes
Laminate flooring is made from wood-based materials that respond to humidity. When moisture levels fluctuate:
- High humidity causes planks to swell, creating pressure between boards and against walls
- Low humidity causes planks to shrink, opening gaps and loosening click-lock joints
- Seasonal changes mean the floor expands in summer and contracts in winter
The recommended indoor humidity range for laminate flooring is between 40% and 60%. Anything outside this range over extended periods can cause persistent noise issues.
Wear and Tear Over Time
Even properly installed laminate flooring can develop creaking as it ages:
- Click-lock joints loosen after years of foot traffic and temperature cycling
- Underlay compresses in high-traffic areas, reducing its cushioning effect
- Individual planks warp or bow slightly, creating movement
- Heavy furniture placed without protective pads can distort planks beneath
Floors that have been down for 5 or more years are more likely to develop age-related creaking, particularly in hallways, kitchens, and living rooms with heavy use.
How to Fix Creaking Laminate Flooring
Once you understand the cause, you can apply the right fix. Work through these steps in order, starting with the simplest solutions.
Step 1. Locate the Exact Source
Walk slowly across the floor and pay attention to where the creaking is loudest. Mark problem areas with painter’s tape so you can focus your repairs.
Listen for whether the noise comes from:
- Between the laminate planks (a clicking or snapping sound at the joints)
- Between the laminate and subfloor (a hollow creaking or flexing feeling)
- From the subfloor itself (a deeper groaning that you can feel through the floor)
This distinction matters because each type requires a different approach.
Step 2. Check and Adjust Expansion Gaps
Remove skirting boards or beading along the wall where creaking is worst. Check whether the laminate is pressing tightly against the wall with no gap.
Laminate flooring requires an expansion gap of 8mm to 12mm around all fixed objects, including walls, door frames, and pipes. If the gap has closed:
- Use an oscillating multi-tool or jigsaw to trim back the laminate edge
- Remove any wedges or debris that may be filling the gap
- Refit skirting boards or beading with enough clearance to allow movement
This is often the quickest and most effective fix for widespread creaking.
Step 3. Address Subfloor Issues
If the creaking is localised to specific areas, the subfloor may be uneven beneath those spots. Options include:
- For timber subfloors: Screw down any loose boards to the joists. Use 50mm screws at 200mm centres for a secure fix
- For concrete subfloors: Use self-levelling compound to fill dips and create a flat surface
- For minor unevenness: Add a thicker, higher-density underlay that can absorb small imperfections
In some cases, you may need to lift sections of laminate to access and repair the subfloor beneath. Since laminate is a floating floor with click-lock joints, this is usually possible without damaging the planks.
Step 4. Apply Lubricant to Joints
For creaking that originates from the laminate joints themselves, applying a dry lubricant can reduce friction and quiet the noise:
- PTFE-based spray is the best option as it doesn’t attract dust or degrade the laminate surface
- Powdered graphite can be worked into joints and provides long-lasting friction reduction
- Talcum powder is a household alternative that can be brushed into gaps between planks
Avoid using WD-40 or oil-based lubricants directly on laminate surfaces, as they can stain or damage the wear layer. If you do use WD-40, apply it sparingly to the joint edges only and wipe away any excess immediately.
Step 5. Secure Loose Planks
If specific planks have come loose from their click-lock connections:
- Lift the affected plank by disassembling from the nearest wall (remove skirting, then unclick planks in sequence until you reach the problem area)
- Clean the joint edges of any debris or damage
- Reconnect the plank, ensuring the click-lock is fully engaged along its entire length
- If the joint is damaged, apply a thin bead of PVA wood glue to the tongue before reconnecting
For areas where lifting is impractical, specialist floor repair adhesive can be injected through small drilled holes to bond the laminate to the subfloor beneath. This eliminates movement without full disassembly.
Step 6. Replace Damaged Planks
When individual planks are warped, cracked, or have broken click-lock edges, replacement is the best long-term solution:
- If the damaged plank is near a wall, disassemble from the wall inward
- If the plank is in the centre of the room, cut it out using a circular saw (set blade depth to laminate thickness only) and fit a replacement with adhesive
- Always acclimatise replacement planks to the room for at least 48 hours before fitting
Keep spare planks from your original installation for this purpose. If you no longer have spares, take a sample to your flooring supplier for the closest match.
How to Prevent Laminate Flooring from Creaking
Prevention is always easier and cheaper than repair. Whether you’re installing new laminate or want to protect an existing floor, these steps significantly reduce the risk of creaking.
1. Ensure Proper Installation from the Start
The most important factor in preventing creaking is correct installation:
- Always leave 8mm to 12mm expansion gaps around all fixed objects
- Use a quality underlay designed specifically for laminate (not carpet underlay)
- Ensure all click-lock joints are fully engaged before moving to the next row
- Follow the manufacturer’s specific installation instructions for your product
- Check the subfloor is level to within 3mm per metre before starting
Professional installation is worth considering if you’re unsure about subfloor preparation or have a complex room layout with many obstacles.
2. Acclimatise Flooring Before Installation
Acclimatisation allows the laminate planks to adjust to your room’s temperature and humidity before being locked into position:
- Unbox the planks and lay them flat in the installation room for at least 48 hours
- Keep the room at its normal living temperature (18 to 22 degrees Celsius)
- Maintain humidity between 40% and 60% during acclimatisation
- Do not store planks in garages, sheds, or unheated spaces before installation
Skipping this step is one of the most common causes of post-installation creaking, as planks that expand or contract after fitting create movement at the joints.
3. Control Indoor Humidity
Maintaining stable humidity levels year-round protects your laminate floor from seasonal movement:
- Use a hygrometer to monitor room humidity (aim for 40% to 60%)
- Run a dehumidifier during humid summer months
- Use a humidifier during dry winter months when central heating runs frequently
- Ensure adequate ventilation in kitchens and bathrooms where moisture levels spike
Consistent humidity is more important than perfect humidity. Large fluctuations cause more damage than a slightly elevated or reduced level that stays stable.
4. Choose the Right Underlay
Underlay plays a critical role in noise prevention. The right underlay:
- Absorbs minor subfloor imperfections that would otherwise cause flexing
- Provides a cushion that reduces impact noise when walking
- Acts as a moisture barrier to protect the laminate from below
- Supports the click-lock joints by preventing excessive downward flex
Avoid using carpet underlay beneath laminate flooring. It is too soft and compressible, which allows the planks to move excessively and puts strain on the joints.
5. Maintain Your Floor Regularly
Ongoing care helps prevent creaking from developing over time:
- Sweep or vacuum regularly to prevent grit from working into joints
- Clean with a damp (not wet) mop using laminate-safe products
- Use furniture pads under all heavy items to distribute weight evenly
- Place rugs or mats in high-traffic areas like hallways and doorways
- Address any spills immediately to prevent moisture ingress at the joints
A well-maintained laminate floor is far less likely to develop noise issues over its lifespan.
6. Invest in Quality Laminate
Not all laminate flooring is created equal. Higher-quality products typically feature:
- Stronger, more durable click-lock systems that maintain a tight connection
- Thicker planks (10mm to 12mm) that resist flexing
- Better moisture-resistant cores (such as HDF rather than MDF)
- More precise milling that ensures consistent joint engagement
Investing in better laminate from the start often prevents the creaking issues that plague cheaper products after just a few years of use.
When to Call a Professional
While many creaking issues can be resolved with DIY solutions, some situations require professional assessment:
- Widespread creaking across the entire floor that suggests a systemic subfloor problem
- Structural sounds like deep groaning from joists or supporting timbers
- Floors that feel noticeably springy or unstable when walked on
- Visible sagging or movement in the subfloor structure
- Moisture damage evident beneath the laminate when sections are lifted
A flooring professional can assess whether the issue is cosmetic (surface noise only) or structural (indicating deeper problems that need addressing before the floor can be properly fixed).
Frequently Asked Questions
Is it normal for new laminate flooring to creak?
Some minor noise during the first few weeks after installation is normal as the floor settles into its environment. The planks are adjusting to the room’s temperature and humidity, and the underlay is compressing slightly under regular use. However, if significant creaking persists beyond 4 to 6 weeks, there is likely an installation or subfloor issue that needs addressing.
Can underlay stop laminate flooring from creaking?
Quality underlay significantly reduces the risk of creaking by cushioning the laminate against subfloor imperfections and reducing friction. However, underlay alone cannot fix problems caused by a severely uneven subfloor or incorrect installation. It works best as a preventive measure rather than a cure for existing issues.
Why does my laminate floor only creak in certain weather?
Laminate flooring responds to humidity changes. In humid conditions, planks swell and push against each other, creating pressure-related creaking. In dry conditions, planks shrink and joints loosen, causing movement-related noise. This seasonal pattern is a clear sign that your indoor humidity needs better management with dehumidifiers or humidifiers as appropriate.
Should I use WD-40 on creaking laminate flooring?
WD-40 can provide temporary relief but is not ideal for laminate floors. It is oil-based, which means it can stain the surface and attract dust over time. PTFE spray or powdered graphite are better choices for lubricating laminate joints. If you do use WD-40, apply it only to the joint edges using a precision nozzle and wipe away any excess immediately.
How long does laminate flooring last before it starts creaking?
Well-installed laminate flooring on a properly prepared subfloor should remain creak-free for 10 to 15 years or more. Budget products or floors installed without adequate preparation may begin creaking within 2 to 5 years. Regular maintenance, stable humidity, and quality underlay all extend the quiet lifespan of your laminate floor.
Can I fix creaking laminate without lifting the floor?
Yes, in many cases. Lubricating joints with PTFE spray or talcum powder, adjusting expansion gaps by trimming edges beneath skirting boards, and injecting repair adhesive through small holes are all methods that avoid full floor disassembly. However, subfloor-related issues usually require lifting at least some sections to access and repair the surface beneath.
