Fix Gaps in Laminate Flooring: A Quick Guide to Gapless Perfection

Over time, gaps may appear between the planks, causing both aesthetic and functional issues in the overall look and feel of the floor. Fixing these gaps is essential for maintaining the appearance and longevity of your laminate flooring.

There is a range of approaches you can take when it comes to addressing these gaps, depending on the severity and extent of the issue. By understanding the primary causes of gaps in laminate flooring and selecting the appropriate solutions for your specific problem, you can ensure that your floor remains visually appealing and structurally sound.

Causes of Gaps in Laminate Flooring

Several factors can cause gaps to appear in laminate flooring. Understanding these causes will help in addressing the issue effectively:

  • Temperature and humidity fluctuations: Laminate flooring materials can expand and contract due to changes in temperature and humidity. This can cause the boards to separate or create gaps over time.

In addition to temperature and humidity fluctuations, improper installation and material defects also contribute to gaps in laminate flooring.

  • Improper installation: A poorly installed laminate flooring system can lead to gaps. Not allowing for an appropriate expansion gap, poor subfloor preparation, or clicking the boards together incorrectly can all result in a compromised installation.
  • Material defects: Low-quality laminate materials or manufacturing defects can also cause gaps to form. Opting for a reputable laminate flooring brand can help mitigate this issue.

To maintain the integrity of your laminate floor, it is crucial to take these factors into account and address them accordingly.

Step-by-Step Guide to Fix Gaps

Assess the Gap

Before proceeding with fixing the gap, it is important to analyze the extent of the problem. Check the size of the gap, its location, and whether it affects adjoining planks. This will help you determine the correct course of action.

Prepare the Area

Start by clearing the area around the affected planks. Remove any furniture and clean the surface of dust and debris. You may also need to temporarily remove baseboards or moldings adjacent to the gap to allow for proper repair.

Close the Gap

Using a rubber mallet or a tapping block, gently tap the affected plank in the direction of the gap. This should help close the gap and realign the planks. Remember to be gentle during this process, as excessive force may damage the planks.

Secure the Planks

Once the gap is closed, it’s crucial to secure the planks in place to avoid recurrence of the problem. Depending on the type of laminate flooring, you could use either wood glue or specialized locking mechanisms for this purpose. Apply the adhesive or secure the locking system according to the manufacturer’s guidelines.

Here’s a summary of the process, including tools and materials you’ll need for each stage:

StageTools & Materials
Assess the Gap– Measuring tape
– Pen and paper
Prepare the Area– Furniture remover
– Broom or vacuum cleaner
– Pry bar (optional)
Close the Gap– Rubber mallet
– Tapping block
Secure the Planks– Wood glue (optional)
– Locking system (optional)

Preventive Measures

Preventing gaps in laminate flooring not only ensures a visually appealing space but also increases the longevity of the floor. To effectively avoid these issues, consider the following tips:

  • Choose high-quality laminate flooring products that are less prone to expansion and contraction.
  • Follow the manufacturer’s instructions for proper installation, ensuring that the floor is installed over a flat and smooth subfloor.
  • Leave a sufficient expansion gap (usually 1/4 inch to 1/2 inch) around the floor’s perimeter to allow for natural expansion and contraction.
  • Maintain a consistent indoor humidity level between 30% and 50%, which can be achieved with the help of a humidifier or dehumidifier, depending on the climate.
  • Address water spills or leaks immediately to prevent damage to the laminate flooring.

Implementing these preventive measures can go a long way in maintaining the integrity and appearance of your laminate floors for years to come.


In summary, fixing gaps in laminate flooring is a manageable task for homeowners.

By employing proper techniques like repositioning boards, using spacers, and addressing more extensive issues with floor leveling compounds, a professional appearance can be maintained.

Regular maintenance ensures longevity and keeps laminate flooring looking its best.
