Is your laminate flooring starting to buckle and warp? Laminate flooring is a popular choice for its durability and aesthetic appeal. However, it can face issues like buckling due to moisture, improper installation, or heavy loads. Addressing buckling promptly is crucial to maintaining the floor's appearance and safety. In this post, you'll learn how to identify, repair, and prevent buckling in laminate flooring.
Buckling in laminate flooring usually appears as raised or warped planks that no longer lie flat. You might notice ripples, waves, or gaps between planks where there should be none. Sometimes, the flooring feels uneven underfoot or makes creaking sounds when walked on. These signs often start small but worsen over time if left unaddressed.
Several factors can cause laminate flooring to buckle:
Moisture Intrusion: Water spills, leaks, or high humidity cause planks to absorb moisture and swell.
Improper Installation: Lack of expansion gaps around the room’s perimeter restricts natural movement.
Subfloor Issues: Uneven or damp subfloors create stress points that push planks upward.
Temperature Changes: Extreme heat or cold can cause planks to expand or contract excessively.
Heavy Loads: Excessive weight or furniture dragging can damage locking mechanisms between planks.
Understanding the root cause helps target repairs and prevent recurrence.
Buckled laminate flooring compromises both function and appearance. It can:
Create tripping hazards.
Damage plank edges or locking systems.
Allow dirt and moisture to penetrate under the floor.
Reduce the lifespan of your flooring.
Lower property value and aesthetic appeal.
Ignoring buckling risks escalating damage, leading to costlier repairs or full replacement.
Tip: Regularly inspect laminate flooring edges and seams for early buckling signs to catch issues before severe damage occurs.
Before starting any repair on buckling laminate flooring, gather all necessary tools and materials to ensure a smooth process. Here’s what you’ll typically need:
Replacement laminate planks: Match the model and color to existing flooring.
Underlayment: If damaged, you’ll need new underlayment to install beneath replacement planks.
Pry bar or crowbar: To carefully lift damaged planks without breaking them.
Hammer and tapping block: For securing new planks into place without damaging edges.
Utility knife: To cut underlayment or trim planks if necessary.
Measuring tape and pencil: For precise measurements and marking cuts.
Pull bar: Helps fit planks tightly in hard-to-reach areas.
Moisture barrier (optional): To add protection if moisture caused the buckling.
Safety gloves and goggles: To protect hands and eyes during removal and installation.
Having these tools ready saves time and reduces frustration during repair.
Working on flooring repairs involves some risks, so keep safety top priority:
Wear gloves to avoid splinters or cuts from sharp plank edges.
Use goggles to protect eyes from flying debris when prying or cutting.
Lift planks carefully to prevent back strain; bend knees and keep back straight.
Ensure good ventilation if you use adhesives or sealants.
Keep work area clear of tripping hazards and children or pets.
Turn off electricity near any floor outlets to avoid shocks if removing baseboards or working near wiring.
These precautions help prevent injuries and keep the repair process safe.
Before removing any planks, evaluate how widespread the buckling is. This step helps decide whether you need to replace a few planks or more extensive repairs.
Inspect all affected areas: Look for raised or warped planks, gaps, or signs of moisture underneath.
Check adjacent planks: Buckling can spread, so examine nearby flooring for early damage.
Examine underlayment: If accessible, assess whether the underlayment is damp, moldy, or deteriorated.
Determine subfloor condition: Uneven or wet subfloors might require repair before reinstalling laminate.
Estimate number of planks to replace: Only replace damaged planks if possible to save cost and effort.
Document your findings and plan the repair accordingly. Sometimes, minor buckling can be fixed by replacing a few planks; severe damage might need professional evaluation.
Start by carefully removing the buckled or damaged laminate planks. Use a pry bar or crowbar to gently lift the edges of the affected planks. If the damaged planks are near a wall, you may need to remove baseboards first to access the edges. Work slowly to avoid damaging adjacent planks or the subfloor beneath.
If the planks are glued down, use a utility knife to score along the edges before prying to reduce damage. For click-lock flooring, gently disengage the locking mechanism by lifting and sliding the plank out. Dispose of damaged planks properly.
Once the damaged planks are removed, inspect the underlayment beneath. If it’s damp, moldy, or deteriorated, replace it to prevent future buckling. Cut the new underlayment to size using a utility knife, ensuring it fits snugly without overlapping.
Lay the underlayment flat, smoothing out wrinkles or bubbles. If moisture caused the buckling, consider adding a moisture barrier beneath the underlayment for added protection. Secure the underlayment according to manufacturer instructions, usually with staples or adhesive.
Before installing new planks, check the subfloor is clean, dry, and level. Begin placing new laminate planks starting from the wall or the area where you removed the old flooring. Align the locking edges carefully and use a tapping block and hammer to secure each plank tightly without damaging edges.
Leave a small expansion gap around the room’s perimeter to allow natural movement. Use a pull bar to fit planks tightly in hard-to-reach corners. Cut planks as needed to fit edges or around obstacles using a utility knife or saw.
After installation, reinstall baseboards if removed. Clean the area thoroughly and inspect the repair to ensure the floor lies flat and looks seamless.
Preventing buckling starts at installation. Make sure to leave an expansion gap around the room’s edges—usually about 1/4 inch. This gap allows the flooring to expand and contract naturally as temperature and humidity change. Without it, planks push against walls or each other, causing buckling.
Use a quality underlayment that matches your laminate type and subfloor. It cushions the floor, absorbs minor subfloor imperfections, and can act as a moisture barrier. Lay it flat without wrinkles or overlaps to avoid uneven surfaces.
Install planks following the manufacturer’s locking system carefully. Avoid forcing planks into place, which can damage edges or locks. Stagger plank seams properly to add stability and reduce stress points.
If installing over concrete or in moisture-prone areas, add a moisture barrier beneath the underlayment. This prevents water vapor from seeping up and causing swelling.
Laminate flooring reacts to moisture changes, so controlling indoor humidity is key. Aim to keep humidity between 30% and 50%. Too much moisture causes planks to swell and buckle; too little can dry them out and cause gaps.
Use a hygrometer to monitor humidity levels regularly. In humid months or damp areas, use dehumidifiers or air conditioning to reduce excess moisture. In dry winter months, a humidifier can help maintain balance.
Fix leaks or water spills immediately. Water pooling on laminate planks quickly leads to damage. Ensure plumbing and appliances nearby are leak-free and that floors dry quickly after cleaning.
Routine care helps prevent problems before they start. Sweep or vacuum regularly to remove dirt and grit that can scratch or wear down protective layers.
Clean spills promptly using a damp cloth, not soaking wet mops. Avoid harsh chemicals; mild cleaners designed for laminate floors work best.
Check expansion gaps and baseboards occasionally to ensure they haven’t been obstructed by furniture or caulk. Furniture pads reduce pressure and prevent dents or scratches.
Inspect flooring edges and seams for early signs of buckling or warping. Catching issues early means simpler repairs and longer floor life.
Tip: Always acclimate laminate flooring in the room for 48 hours before installation to reduce expansion issues caused by sudden temperature or humidity changes.
Sometimes, buckling damage goes beyond simple DIY fixes. If you notice large areas of warped or lifted planks, persistent moisture issues, or damage spreading rapidly, it’s wise to call a professional. Experts can assess subfloor problems, moisture sources, or structural concerns that aren’t obvious. They also have specialized tools and experience to handle complex repairs or full replacements safely and efficiently.
Professional help is especially important if:
The subfloor is uneven, wet, or moldy.
Damage covers more than a few square feet.
You lack the right tools or skills for extensive repairs.
You want warranty coverage or insurance claims.
Getting expert advice early can save money, time, and frustration later.
When repairs aren’t enough, replacing laminate flooring might be the best choice. You have several options:
Full Replacement: Remove all old laminate, underlayment, and sometimes the subfloor. Install new laminate or another flooring type from scratch.
Partial Replacement: Replace only severely damaged sections. This requires careful matching of plank style and color to existing floor.
Upgrade Flooring Type: Consider switching to engineered hardwood, vinyl plank, or tile for better moisture resistance or durability.
Choosing the right option depends on budget, damage extent, aesthetics, and future use. Full replacement offers a fresh start but costs more. Partial fixes save money but may not last if underlying issues persist.
Costs vary widely based on repair scope, materials, and labor. Here’s a rough breakdown:
| Task | Estimated Cost Range |
|---|---|
| DIY plank replacement | $50 to $150 (materials) |
| Professional repair | $200 to $600 |
| Full laminate replacement | $1,500 to $4,000+ |
| Flooring upgrade | $3,000 to $7,000+ |
Additional expenses may include subfloor repair, moisture barriers, or furniture moving. Always get multiple quotes from contractors and compare warranties.
Investing in quality materials and professional installation reduces future buckling risks and increases flooring lifespan.
