How To Fix Side Gaps In Laminate Flooring


Laminate flooring is a popular choice for many homeowners due to its durability, affordability, and easy installation. However, one common issue that can occur with laminate flooring is side gaps. These side gaps can develop over time or may occur during the installation process. Side gaps not only affect the aesthetic appeal of the flooring but can also lead to damage if left unaddressed. In this article, we will explore the causes of side gaps in laminate flooring and provide you with step-by-step instructions on how to fix them.


1. Understanding the Causes of Side Gaps

Before diving into the solutions, it is important to understand the factors that contribute to side gaps in laminate flooring. The most common causes include:

  • Poor installation: Mistakes made during the installation process, such as failing to leave an expansion gap or using improper tools, can lead to side gaps.
  • Humidity and temperature changes: Laminate flooring is susceptible to changes in humidity and temperature, which can cause the planks to expand or contract, resulting in side gaps.
  • Subfloor irregularities: An uneven subfloor or debris left on the subfloor can prevent the laminate planks from fitting tightly together, creating gaps.

2. Fixing Side Gaps in Laminate Flooring

If you notice side gaps in your laminate flooring, don’t worry! Here are the steps to fix them:

Step 1: Inspect the Flooring

Thoroughly inspect the affected area to determine the extent of the side gaps. Look for any debris, loose planks, or signs of damage that may need to be addressed before proceeding with the repair.

Step 2: Clean the Gaps

Use a soft brush or vacuum cleaner to remove any dirt or debris from the side gaps. This will ensure a clean surface for the repair.

Step 3: Assess the Gap Size

Measure the width of the side gap using a tape measure or caliper. This measurement will help you determine the best method for closing the gap.

Step 4: Use a Flooring Installation Kit

If the side gaps are small, you can use a flooring installation kit to close them. These kits typically include a tapping block, pull bar, and spacers. Follow the manufacturer’s instructions to insert the spacers into the side gaps and use the tapping block and pull bar to gently tap the laminate planks into place.

Step 5: Use Wood Glue

If the side gaps are larger, you may need to use wood glue to close them. Apply a small amount of wood glue to a syringe or narrow-tipped applicator and carefully insert it into the gap. Use clamps or heavy objects to hold the planks together until the glue dries.

Step 6: Replace Damaged Planks

If the side gaps are accompanied by damaged or warped laminate planks, it may be necessary to replace them. Use a circular saw or a jigsaw to carefully remove the damaged planks, and then install new ones according to the manufacturer’s instructions.

Step 7: Monitor and Maintain

After fixing the side gaps, it is essential to monitor and maintain your laminate flooring to prevent future issues. Avoid exposing the flooring to excessive moisture, use furniture pads to prevent scratches, and regularly clean the surface with a laminate-specific cleaner.


Fixing side gaps in laminate flooring is a straightforward process that can be accomplished with basic tools and materials. By understanding the causes of side gaps and following the steps outlined in this article, you can restore the appearance and functionality of your laminate flooring. Remember to always prioritize proper installation techniques and regular maintenance to prevent side gaps from occurring in the first place.
