Laminate flooring is a popular choice for its durability and affordability, but even the most resilient flooring can encounter problems. One common issue is lifting or buckling, which can be unsightly and even create tripping hazards. This comprehensive guide will walk you through understanding why your laminate flooring is lifting, and most importantly, how to fix laminate flooring that is lifting, offering solutions for various scenarios and levels of expertise. We’ll cover everything from identifying the cause to performing the necessary repairs, empowering you to tackle this problem confidently.
Laminate flooring is composed of several layers pressed together. When moisture gets underneath, it causes the core layer to expand, leading to the top layer lifting or buckling. This isn’t just a cosmetic issue; lifting laminate can create uneven surfaces, potential tripping hazards, and compromise the overall structural integrity of your
floor.
Identifying the Cause of Lifting
Moisture Intrusion
The most common culprit is excessive moisture. This could originate from leaks (plumbing, roof, windows), high humidity, spills that weren’t properly cleaned, or even flooding. The water seeps beneath the laminate, causing the underlayment and core to swell.
Improper Installation
Incorrect installation is another major cause. Insufficient expansion gaps around the perimeter of the room (especially near walls and doorways), improper underlayment use, or using too much or too little adhesive can all contribute to lifting. Poor subfloor preparation also plays a significant role.
Subfloor Issues
The condition of your subfloor is crucial. A damaged, uneven, or warped subfloor can exert uneven pressure on the laminate, causing it to lift in certain areas. Consider using a self-leveling compound to rectify any significant subfloor imperfections.
Assessing the Damage
Before attempting any repair, carefully assess the extent of the lifting. Is it a small area, or is a significant portion of the floor affected? Are there any visible cracks or damage to the laminate boards themselves? Knowing the scale of the problem guides your chosen repair method.
Simple Fixes for Minor Lifting
Reapplying Adhesive
For minor lifting in small areas, you might be able to re-adhere the laminate. Carefully lift the edge of the board and apply a small amount of suitable wood adhesive (check for compatibility with laminate) under the lifted section. Then, firmly press the board back down and weigh it down using heavy objects for several hours to ensure proper adhesion.
Repairing Moderate Lifting
If the lifting is more extensive, you’ll need a more comprehensive approach. This might involve removing and replacing several affected planks.
Removing Affected Planks
Carefully pry up the affected laminate planks using a putty knife or pry bar, working from the edge towards the center. Be cautious not to damage surrounding planks. You may need to remove several surrounding planks to access the problem area completely.
Replacing Damaged Planks
Once the damaged planks are removed, ensure the subfloor is clean, dry, and level. Replace the planks with new ones, using a compatible underlayment and ensuring proper expansion gaps.
Dealing with Extensive Lifting
For significant lifting or buckling across a large area, it might be more cost-effective and efficient to replace a significant portion or even all of your laminate flooring. This often indicates more serious underlying issues like subfloor damage or extensive moisture problems that need to be addressed before new flooring is installed.
Preventing Future Lifting
Maintaining Proper Humidity Levels
Keep humidity levels in your home within recommended ranges (ideally between 30% and 50%). This helps prevent excessive moisture from affecting your laminate flooring. Using a dehumidifier in damp environments can be beneficial.
Addressing Leaks Promptly
Fix any plumbing leaks, roof leaks, or window leaks immediately to prevent water damage. Regularly inspect your home for potential sources of water intrusion.
Using a Moisture Barrier
When installing new laminate flooring, consider using a moisture barrier underlayment to provide an extra layer of protection against moisture damage. A high-quality underlayment will improve the life of your laminate.
Choosing the Right Adhesive
The type of adhesive you use is critical. Choose an adhesive specifically designed for laminate flooring and compatible with your underlayment. Read the manufacturer’s instructions carefully before applying.
Tools and Materials Needed
- Putty knife or pry bar
- Hammer
- Measuring tape
- Utility knife
- Laminate flooring adhesive
- Replacement laminate planks (matching your existing flooring)
- Heavy objects for weighting down repairs
- Safety glasses and gloves
Understanding Underlayment
Underlayment serves as a cushioning layer between the subfloor and laminate, providing insulation, sound dampening, and moisture protection. Choosing the correct type is essential; consider options with moisture-resistant properties for added protection.
Cost Considerations
The cost of fixing lifting laminate flooring will vary depending on the extent of the damage and the materials needed. Minor repairs may be inexpensive, while major repairs or complete replacements could be significantly more costly.
Comparing DIY vs. Professional Repair
For minor lifting, a DIY approach might be feasible. However, for extensive damage, it’s often best to call a professional flooring installer. Professionals possess the experience and tools to handle complex repairs efficiently and effectively.
Laminate Flooring: Long-Term Care
Regular maintenance is key to prolonging the lifespan of your laminate floor. Sweep or vacuum regularly to remove dirt and debris. Clean spills promptly to prevent moisture damage. Avoid using harsh chemicals or abrasive cleaners.
When to Call a Professional
If you’re uncomfortable tackling the repair yourself, or if the damage is extensive, it’s advisable to contact a qualified flooring professional. They can accurately assess the situation, perform necessary repairs, and ensure the long-term integrity of your floor.
Frequently Asked Questions
What causes laminate flooring to lift?
The most common cause is moisture intrusion, either from leaks, high humidity, or spills. Improper installation, such as inadequate expansion gaps or a damaged subfloor, can also contribute.
Can I fix lifting laminate myself?
Minor lifting in small areas can often be repaired with DIY methods, such as reapplying adhesive. However, more extensive damage may require professional help.
What type of adhesive should I use?
Use a construction adhesive specifically designed for laminate flooring. Always check for compatibility with your type of laminate and underlayment.
How can I prevent laminate flooring from lifting in the future?
Maintain proper humidity levels, address leaks promptly, and use a quality moisture-resistant underlayment during installation.
What if the subfloor is damaged?
A damaged subfloor needs to be addressed before installing laminate or attempting repairs. This may involve repairing or replacing sections of the subfloor, or even using a self-leveling compound to create a smooth surface.
How much does it cost to fix lifting laminate flooring?
Costs depend on the extent of the damage. Minor repairs are inexpensive, while full replacements can be costly.
Final Thoughts
Fixing lifting laminate flooring can range from a simple DIY project to a more involved undertaking requiring professional assistance. By understanding the causes of lifting and following the steps outlined in this guide, you can effectively address the problem and restore the integrity and beauty of your floor. Remember to prioritize addressing any underlying moisture issues to prevent future occurrences. If you’re unsure about any aspect of the repair process, don’t hesitate to contact a qualified flooring professional.
