How to Fix a Gap in Laminate Flooring: Expert Tips & Real-Life Fixes for Laminate Floor Gaps in US Homes

Laminate flooring is a favorite for American homeowners thanks to its durability and sleek look. But one common issue—even with careful installation—is a gap that appears between planks over time. I’ve seen this dozens of times in projects, from old rentals in Chicago to high-end homes in Dallas. Let’s break down exactly how to fix a gap in laminate flooring so your room looks flawless again.

First, understand why these gaps happen. Floors naturally expand and contract as temperatures and humidity shift. If the laminate wasn’t properly acclimated before installation, or if the subfloor isn’t flat, gaps may pop up. Sometimes, it’s as simple as foot traffic pushing planks apart near busy entryways. One client in San Francisco found a half-inch gap along their living room wall after their kids spent months using the room as a hotspot for dance parties!

Project Planning: Assess the Gap

Before you fix your floor, inspect the width and length of the gap. Most gaps can be handled with simple tools, but wide or recurring gaps may point to underlying installation problems. I typically recommend checking for moisture near gaps—high humidity or a recent spill can impact laminate’s movement.

If you’re planning a larger repair, consider mapping out your room with a simple room planner to strategize your work and visualize the space after the fix.

Choose the Right Tools

Here’s what you’ll need:

1. Cleaning supplies (vacuum, microfiber cloth)
2. Laminate pull bar or floor gap fixer tool
3. Tapping block and hammer
4. Glue (optional, for persistent gaps—not recommended for floating floors)
5. Painter’s tape

Quick tip: For tricky spots near walls, a specialized gap fixer tool can save you tons of frustration and is readily available at most US hardware stores.

Step-by-Step: Closing the Gap

Follow these simple steps to fix that unsightly gap:

1. Clean the Area: Debris hides in gaps and prevents proper alignment. Vacuum thoroughly before starting.
2. Secure the Floating Floor: If your flooring is a floating installation, use a pull bar. Insert the bar in the gap, protect the laminate with painter’s tape, then gently tap the bar towards the plank to close it. Go slow—too much force risks chipping.
3. Use a Floor Gap Fixer: Stick the gap fixing tool (adhesive pad or suction device) onto the plank, and gently tap. You’ll see the boards move closer with each tap.
4. Check for Underlying Issues: If the gap keeps returning, inspect for uneven subfloors or excessive humidity. Sometimes a simple fix reveals a bigger problem.

If you’re unsure about trying repairs yourself, or if you have persistent gaps throughout the room, it might be time to consult an expert. In one of my DIY client projects in Denver, they fixed a narrow gap with a pull bar, only to discover several more due to a sloping subfloor—leading to a full-floor reinstallation.

Level of Detail & Time

The average gap fix shouldn’t take longer than an afternoon, especially if you’re tackling only a few problem spots. The majority of homeowners report success within 1–2 hours for a standard room, according to Houzz Design Insights 2025.

High-traffic areas or large rooms might require extra time. Always be patient and check plank alignment frequently, especially with older or lower-quality laminate.

Case Study: Family Room Makeover

A Maryland family discovered a growing gap right in the center of their laminate floor. After checking for moisture and finding none, they used a floor gap fixer pad, taping off adjacent planks for protection. They methodically nudged the boards together, finishing with a gentle hammer tap. The result? The gap vanished, the floor looked seamless, and they avoided costly reinstallation—all in a single evening.

Common Mistakes & Fixes

1. Skipping the Clean: Dust or grit blocks the planks from sliding easily.
2. Tapping Too Hard: Can chip edges—always use a block and tape.
3. Using Glue on a Floating Floor: This can interfere with the natural expansion and contraction—use glue only for glued-down installations.

FAQ

1. How do I prevent gaps from returning in my laminate flooring?
2. Acclimate your planks for 48 hours before installation and monitor humidity levels. Fix gaps promptly to avoid bigger issues.
3. Can I fix a gap without specialized tools?
4. Yes—a screwdriver, cloth-wrapped block, and a hammer work in a pinch, but dedicated gap fixer tools are safer and more effective.
5. Should I use glue for persistent laminate gaps?
6. Only in glue-down installations. For floating floors, glue can cause more problems due to restricted plank movement.
7. Will a gap in the flooring affect home resale value?
8. Visible gaps can make spaces look poorly maintained and may deter buyers. Quick fixes help preserve real estate value, especially in competitive markets.
9. Can uneven subfloors cause frequent gaps?
10. Absolutely. Persistent or recurring gaps are often signs your subfloor needs leveling.
11. Are there free tools to visualize my repair?
12. Try using a digital floor plan creator before making major repairs for layout and fix planning.
13. How long does it take to repair laminate flooring gaps?
14. Most fixes can be done in 1–2 hours for small spaces. Larger jobs may take longer.
15. What if I see gaps in more than one area?
16. Multiple gaps may mean poor installation or an issue with humidity. Consider consulting a flooring pro.
17. Can changes in season affect my flooring?
18. Yes—seasonal temperature and humidity swings cause planks to expand or contract. Monitoring indoor climate helps.
19. Is it possible to fix gaps without lifting planks?
20. In most cases, yes. A gap fixer tool usually slides planks together without full removal.
21. Will fixing the gap change the look of my floor?
22. If done carefully, your repair should be invisible. Always match planks precisely and work slowly.
23. Are professional repairs expensive?
24. Small fixes are affordable, but extensive reinstallation costs more. DIY is budget-friendly, especially for single gaps.
