Lifted Laminate Floor: The Hidden Causes You Need To Know

Laminate flooring, renowned for its durability and aesthetic appeal, can occasionally succumb to an unwelcome issue: lifting. This phenomenon, characterized by the separation of planks from the subfloor, can be both unsightly and disruptive. Understanding the underlying causes of laminate floor lifting is paramount to devising effective solutions.

Moisture Intrusion

Moisture is the arch-nemesis of laminate flooring. When excessive moisture penetrates the planks through gaps, joints, or edges, it can cause them to expand and buckle. This expansion can lead to lifting, as the planks no longer fit snugly together.

Inadequate Expansion Gap

Laminate flooring requires an expansion gap around its perimeter to accommodate natural expansion and contraction due to temperature and humidity fluctuations. If this gap is too narrow or nonexistent, the planks will have nowhere to expand, resulting in buckling and lifting.

Uneven Subfloor

An uneven subfloor can create pressure points that cause laminate planks to lift. This is especially common in older homes with uneven or sagging floors. The uneven surface creates gaps between the planks, allowing moisture to seep in and exacerbate the problem.

Improper Installation

Laminate flooring installation requires precision and attention to detail. If the planks are not properly locked together or secured to the subfloor, they may become loose over time and lift.

Extreme Temperature Fluctuations

Laminate flooring is designed to withstand normal temperature variations, but extreme fluctuations can cause it to expand or contract excessively. This can lead to buckling and lifting, particularly in areas exposed to direct sunlight or radiant heat.

Heavy Objects

Placing heavy objects on laminate flooring can create excessive pressure, especially if the objects have sharp edges or points. This pressure can damage the planks and cause them to lift.

Lack of Underlayment

Underlayment is a crucial component of laminate flooring installation. It provides a moisture barrier, cushions the floor, and helps to reduce noise. Without underlayment, laminate planks may be more susceptible to moisture damage and lifting.

How to Resolve Laminate Floor Lifting

Resolving laminate floor lifting depends on the underlying cause. Common solutions include:

• Addressing Moisture Intrusion: Seal any gaps or cracks around the perimeter of the flooring, fix leaks, and use a dehumidifier to reduce moisture levels.
• Creating an Expansion Gap: Remove any existing baseboards or trim to create an expansion gap of at least 1/4 inch around the perimeter of the flooring.
• Leveling the Subfloor: If the subfloor is uneven, it may need to be leveled using self-leveling compound or plywood.
• Reinstalling the Flooring: In severe cases, it may be necessary to remove and reinstall the laminate flooring, ensuring proper locking and securing to the subfloor.
• Replacing Damaged Planks: If individual planks are damaged beyond repair, they can be replaced with new ones.
• Using Heat to Repair Buckles: In some cases, applying heat to buckled planks can help them to relax and return to their original position.

Preventing Laminate Floor Lifting

Prevention is key to maintaining a pristine laminate floor. Here are some tips:

• Control Moisture: Keep humidity levels in check with a dehumidifier, especially in areas prone to moisture.
• Ensure Proper Installation: Hire a qualified professional to install your laminate flooring according to the manufacturer’s instructions.
• Use Underlayment: Always use a moisture-resistant underlayment beneath laminate flooring.
• Avoid Heavy Objects: Distribute heavy furniture and appliances evenly across the floor to avoid excessive pressure on individual planks.
• Maintain Temperature Stability: Avoid extreme temperature fluctuations by using curtains or blinds to block direct sunlight and adjusting heating and cooling systems as needed.

Answers to Your Most Common Questions

Q1: Can I repair laminate floor lifting myself?
A1: Minor repairs, such as filling gaps with caulk or replacing damaged planks, can be done by homeowners with basic DIY skills. However, major repairs, such as leveling the subfloor or reinstalling the entire floor, should be left to professionals.

Q2: How long does it take to repair laminate floor lifting?
A2: The repair time depends on the extent of the damage. Minor repairs can be completed in a few hours, while major repairs may take several days or even weeks.

Q3: How much does it cost to repair laminate floor lifting?
A3: Repair costs vary depending on the severity of the damage, the size of the area to be repaired, and the materials used. Minor repairs can cost around $100, while major repairs may cost several thousand dollars.
