What Causes Bubbles in Laminate Flooring?
Bubbles or raised areas in laminate floors can be caused by several factors, often related to moisture, improper installation, or subfloor issues. Here are the most common reasons:
Trapped Moisture: One of the leading causes of bubbling in laminate flooring is moisture seeping beneath the planks. If the subfloor is not dried correctly before installing laminate flooring or spills and humidity levels are not controlled, the flooring can swell and create bubbles.
Poor Laminate Floor Installation: If laminate planks are installed without the necessary expansion gap around the edges, the flooring can buckle as it expands and contracts with temperature and humidity changes. Proper spacing is crucial to prevent bubbling.
Subfloor Issues: An uneven or improperly prepared subfloor can create gaps or pressure points that lead to bubbles forming over time. If the subfloor has dips or high spots, the laminate flooring will not lay flat, causing issues later.
Low-Quality Adhesive in Glue-Down Installations: Some laminate flooring installations use adhesive to secure planks in place. If low-quality glue is used or the adhesive does not cure properly, bubbles may appear as the flooring shifts.
Water Damage or Excessive Humidity: Laminate floors are not waterproof, so prolonged exposure to moisture from leaks, wet mopping, or high humidity can lead to bubbling. Maintaining proper humidity levels and cleaning spills quickly is essential to prevent damage.
How to Fix Bubbles in Laminate Flooring
If you’ve noticed bubbling in your laminate floors, depending on the cause, there are several ways to address the problem.
Puncture and Repair Small Bubbles: For minor bubbling, you can use a sharp needle or pin to create a tiny hole in the bubble, then press down gently to release trapped air or moisture. Placing a heavy object over the area for a few hours may help flatten it.
Replace Damaged Planks: If the bubbling is severe, replacing the affected planks is the best solution. Carefully remove the damaged section, ensure the subfloor is dry and level, and install a new plank.
Improve Moisture Control: If excess moisture is the issue, using a dehumidifier or improving ventilation can help prevent further bubbling. If the bubbling is widespread due to water damage, a complete replacement may be necessary.
Check for Proper Installation Techniques: If your laminate flooring was not installed correctly, issues like bubbling can arise. Ensuring a proper expansion gap is left during laminate floor installation and using high-quality materials can prevent future problems.
