Why Do Bubbles Form in Laminate Flooring and How Can You Fix Them?

Laminate flooring offers a stylish, affordable alternative to hardwood and is a popular choice for many homeowners in Lynnwood, WA. But what happens when bubbles begin to form under the surface? These unsightly imperfections can ruin the clean look of your floors and lead to bigger problems if left untreated. In this guide, we’ll explore the causes of bubbling in laminate flooring, prevention strategies, and how to fix the issue effectively.
 

What Causes Bubbles in Laminate Flooring?

Several factors can lead to bubbles or raised areas in laminate flooring. Understanding the root causes is key to prevention:
 

  • Moisture Under the Floor: Water or moisture is the most common culprit. Laminate isn’t fully waterproof, so even small spills that seep under the planks can cause expansion and bubbling.
  • Poor Laminate Flooring Installation: If the floor is not installed properly, such as failing to leave an expansion gap or not preparing the subfloor correctly, pressure can build up and result in bubbles.
  • Trapped Air During Installation: Air can get trapped during the adhesive process if glue-down laminate is used. This often happens during DIY attempts at installing laminate flooring without proper tools or technique.
  • Low-Quality Materials: Inexpensive or defective laminate planks are more prone to bubbling due to thinner wear layers and weaker locking systems.

 

How to Fix Bubbles in Laminate Flooring

The method of repair depends on the cause and severity:
 

  • For Minor Bubbles: Try using a needle to puncture the bubble and press it down. Then weigh it down with something heavy for several hours.
  • Replace the Damaged Plank: In most cases, the best solution is to remove and replace the bubbled plank. If the flooring is floating, you can usually unlock and reinstall.
  • Check for Moisture Sources: If water damage is the issue, locate and resolve the source (leaky pipe, excess humidity, etc.) before replacing any flooring.
  • Improve Subfloor Conditions: An uneven or poorly prepared subfloor can also cause issues. A level, dry base is essential when performing any laminate floor installation.

 

How to Prevent Future Problems

If you’re planning on installing laminate flooring, make sure the job is done right the first time. Here are a few key tips:
 

  • Acclimate flooring for 48 hours before installation
  • Use underlayment for moisture protection and comfort
  • Learn how to install laminate flooring from professional resources or hire certified installers
  • Leave a proper expansion gap around walls and fixtures
  • Clean up spills immediately
