Understanding Laminate Floor Buckling
Laminate floor buckling describes when planks lift, warp, or separate from each other, creating uneven or raised surfaces. This issue compromises both appearance and safety as tripping hazards increase. Recognizing the signs early can help prevent further damage and costly repairs. Understanding the dynamics of laminate flooring is crucial before addressing any issues.

Main Causes Of Laminate Floor Buckling
Moisture Intrusion
Moisture is the leading cause of laminate floor buckling. Whether it’s high humidity, spills, mopping with excess water, or leaks from appliances, moisture can seep into the floorboards. Laminate, made from wood-based materials, absorbs water and expands, causing planks to push upwards and buckle. In regions with climate fluctuations, this risk increases significantly.
Lack Of Expansion Gaps
Expansion gaps are vital during installation. Laminate flooring needs small gaps around the perimeter to accommodate natural expansion and contraction due to temperature and humidity changes. Without these, planks have nowhere to expand, leading to pressure buildup and buckling. Ensuring proper expansion joints is a standard best practice.
Poor Installation Practices
Improper installation can compromise your flooring’s stability. Installing over uneven subfloors, using incorrect underlayment, or not acclimating planks to the room’s humidity can all increase the susceptibility to buckling. Professionals recommend allowing laminate to adjust to the living space for up to 48 hours before installation.
Subfloor Problems
An uneven or damp subfloor often leads to laminate buckling. If the subfloor isn’t level or contains moisture, the support under your laminate weakens. Over time, this creates pressure points that may make planks shift, buckle, or crack. Addressing subfloor issues before installing laminate is essential.
Major Temperature Fluctuations
Sudden swings in temperature can cause flooring to expand or contract rapidly. Laminate materials respond to heat and cold. Homes with poor climate control, such as cabins or seasonal rentals, can see more frequent buckling due to rapid environmental changes.
Recognizing Early Warning Signs Of Buckling Laminate Floors
Early detection helps limit damage and reduce repair costs. Here are key symptoms to look for:

- Bubbling or Raised Planks: Individual planks appear uneven or ballooned upwards.
- Visible Gaps Between Boards: Gaps indicate pressure or movement.
- Soft Or Soggy Texture Underfoot: This suggests trapped moisture.
- Creaking Or Popping Sounds: Noise when walking may hint at displacement.
- Discoloration Or Staining: Signs of water damage or mold buildup.
Common Areas Prone To Laminate Floor Buckling In American Homes
Bathrooms, kitchens, basements, and entryways are most vulnerable due to high humidity and frequent water exposure. Homes in states prone to hurricanes, flooding, or high rainfall—like Florida, Louisiana, or Washington—experience higher risks as well.
Preventive Measures To Avoid Laminate Floor Buckling
Proper Installation Techniques
Hire certified installers who use quality underlayment and follow manufacturer guidelines. Make sure planks are allowed to acclimate to room temperature and moisture for at least 48 hours. Install expansion gaps of at least 0.25 inches around the room perimeter and at transitions.
Moisture Control In The Home
Use dehumidifiers in damp areas, promptly clean spills, and avoid wet mopping. Regular maintenance and quick response to water leaks—from dishwashers, refrigerators, or water heaters—will help preserve your flooring’s integrity.
Quality Laminate Selection
Choose water-resistant or waterproof laminate for high-risk areas. Many modern products are designed specifically for kitchens, bathrooms, and basements, offering extra layers of protection against moisture.
Subfloor Preparation
Ensure subfloors are dry, clean, and level before installation. Moisture barriers or vapor barriers can be installed over concrete slabs for additional protection, especially in basements or ground-level rooms.
How To Fix Buckling Laminate Flooring
Step 1: Identify The Extent Of Damage
Pinpoint which planks are affected, and determine if the issue is localized or widespread. Sometimes, only a few boards near a kitchen sink or door need attention; in other cases, problems may span several rooms.
Step 2: Remove Damaged Planks And Assess Subfloor
Carefully remove suspect planks without damaging surrounding flooring. Inspect the underlayment and subfloor for moisture or uneven spots. If moisture is present, allow it to dry completely before any repairs.
Step 3: Correct Underlying Causes
Address moisture leaks, fix or replace subfloor sections, and add or adjust expansion gaps. Rectifying installation or environmental problems prevents recurrence.

Step 4: Replace With New Planks
Use matching or similar planks for a seamless repair. Follow proper installation protocols, ensuring expansion gaps and correct underlayment placement.
Step 5: Monitor And Maintain
After repairs, keep humidity levels stable and examine the floor periodically. Promptly address minor spills or leaks to maintain the floor’s protection and appearance over time.
