Laminate flooring offers a cost-effective alternative to hardwood floor installation, but gaps between planks can be a common issue. Simple Flooring, a leading laminate floor installer in Chicago, is here to guide you through the reasons behind these gaps and how to fix gaps in laminate flooring.
Gap Size | Cause | Solution |
---|---|---|
Small (<1/8") | Natural temperature fluctuations. | Wait for seasonal shifts or fill with matching caulk. |
Medium (1/8"-1/4") | Changes in humidity levels. | Adjust the room’s climate and consult an expert if needed. |
Large (>1/4") | Poor installation or structural movement. | Replace the boards professionally to fix the issue. |
Causes of Laminate Flooring Gaps

Step-by-Step Guide to Fixing Laminate Floor Gaps
Step 1: Inspect and Measure the Gap
Thoroughly clean the area to remove dust or debris, then measure the gap. Take note if gaps appear during specific seasons, as this may signal a climate-related issue.
Step 2: Adjust the Room’s Environment
Set your room temperature between 60-80°F and maintain humidity at 35-55%. Give the flooring 48 hours to adjust naturally; smaller gaps often close on their own under the right conditions.
Step 3: Apply a Temporary Solution
For gaps smaller than 1/4 inch, use color-matched silicone caulk. Apply it carefully, then immediately wipe away any excess with a damp cloth for a smooth finish.
Step 4: Call the Pros for Persistent Issues
If the gap remains or is larger than 1/4 inch, it’s time to bring in flooring professionals. They’ll use specialized tools to realign your flooring or replace damaged boards.
Tips for Gap-Free Laminate Flooring
Climate Control
Keep indoor temperatures consistent (60-80°F) to prevent laminate boards from expanding or contracting.
Control Humidity
Aim for 35-55% humidity to minimize the risk of swelling or shrinking.
Acclimation
Allow acclimation. Let new boards acclimate for 48-72 hours before laminate flooring installation.

Avoid Bad Laminate Flooring Installation
Rely on experienced professionals like Simple Flooring to ensure correct laminate floor installation.
- Quickly clean up spills to prevent warping or swelling.
- Use a vapor barrier to protect against moisture, especially in areas prone to dampness.
- Prevent scratches by using gentle cleaning tools and avoiding abrasive materials.
- Avoid walking on the floor for 24 hours post-installation to allow for proper settling.
Implementing these precise measures ensures a gap-free, long-lasting laminate floor.
