Laminate flooring is a popular flooring choice for many homeowners. It is durable, affordable, and easy to install. However, over time gaps can form between the planks of laminate flooring due to factors like seasonal contraction and expansion. This leaves unsightly cracks that can collect dirt and moisture. So can you caulk these gaps to fill them in? Let’s take a closer look at whether caulking gaps in laminate flooring is recommended.

What causes gaps in laminate flooring?
There are a few key reasons that gaps form between laminate flooring planks:
- Seasonal contraction and expansion – Laminate flooring will expand and contract slightly with changes in humidity and temperature. This natural movement can cause gaps to form.
- Uneven subfloor – If the subfloor underneath the laminate is uneven, it can cause some planks to be higher or lower than others, creating gaps.
- Improper installation – Gaps can form if laminate flooring is not installed properly, with inadequate expansion gaps left around the perimeter.
- Structural issues – Major foundation or structural issues with the home can cause the subfloor to shift, leading to gaps between laminate planks.
So in most cases, gaps are caused by natural fluctuation in the flooring or imperfections in the subfloor or installation. Filling these gaps with caulk may seem like an easy solution, but is it recommended?
Is caulking gaps in laminate flooring a good idea?
Caulking may appear to solve the problem of unsightly gaps in laminate flooring. However, most flooring experts advise against caulking gaps for several reasons:
- Caulk can prevent natural expansion and contraction, leading to buckling or damage of planks.
- Caulked gaps can come loose over time as the flooring moves, creating even more of a tripping hazard.
- Trapped moisture and dirt in caulked gaps can damage laminate and cause odor issues.
- Caulk has a different appearance from the flooring and draws more attention to the gaps.
Instead of caulking, it is better to address the underlying cause of the gaps and make corrections to create a long-lasting solution.
Allowing for normal expansion and contraction
Laminate flooring requires room to expand and contract with changes in humidity and temperature. Caulking gaps can restrict this natural movement, leading to buckling or damage over time. It’s best to leave small gaps unfilled to allow the flooring to move freely.
Checking for subfloor issues
An uneven subfloor is a common reason for gapping. Inspect the subfloor and make corrections as needed to create a flat, stable surface for the laminate. Adding plywood underlayment can help smooth out minor subfloor imperfections.
Reinstalling flooring properly
If gaps are due to improper installation, the best permanent fix is to remove and reinstall the flooring. Be sure to leave 1/4″ expansion gaps around the perimeter and follow all manufacturer instructions during installation.
Addressing structural problems
Gaps caused by settling foundations or major structural issues need to be addressed at the source. Consult a structural engineer to determine solutions, which may involve foundation repairs.
Best alternatives to caulking laminate flooring gaps
Instead of caulking, here are some better options for dealing with unsightly gaps in laminate flooring:
Install trim pieces or quarter round
Trim like quarter round or shoe molding can cover gaps between the laminate and baseboards or walls. This allows the flooring to expand and contract while hiding gaps.
Use filler strips
Filler strips that match the laminate flooring can be inserted into gaps to make them less noticeable while still allowing room for slight movement.
Replace boards
For large gaps or planks that are damaged or lifting, replacing individual boards can effectively eliminate gaps.
Add flooring transitions
Transitions between rooms or flooring types can be used to cover large gaps at thresholds.
Conclusion
Caulking laminate flooring gaps may seem like a quick fix but can cause bigger problems down the road. It’s better to address the underlying cause of gapping and use alternatives like trim, filler strips, plank replacement, or transitions. Allowing the laminate to move freely prevents damage while effective solutions like moldings hide unsightly gaps. With the right approach, you can solve laminate flooring gaps without caulk.
FAQ
Is caulk bad for laminate floors?
Yes, caulking gaps in laminate flooring is generally not recommended. Caulk can damage laminate flooring by preventing the planks from expanding and contracting naturally. This can lead to buckling or warped boards over time.
What is the best caulk for laminate flooring?
Caulk should not be used on laminate flooring gaps. However, if you do choose to caulk, an acrylic latex caulk labeled for use with flooring is best. Avoid silicone caulks, which can damage many flooring surfaces.
How do you fix gaps between laminate planks?
Instead of caulking, the best ways to fix gaps between laminate planks are:
- Install quarter round or trim molding to cover gaps.
- Use filler strips that match the laminate color.
- Replace individual planks as needed.
- Address subfloor issues causing uneven planks.
When should you caulk laminate flooring?
Caulking laminate flooring gaps is not recommended in most situations. The only exception is using acrylic latex caulk on very small gaps right after initial installation while the adhesive cures. But in general, caulk should be avoided on laminate flooring.
What can I use to fill gaps in laminate flooring?
Some better alternatives to fill gaps in laminate flooring include:
- Filler strips or boards matching the laminate color
- Molding like quarter round or baseboard trim
- Flooring transitions between rooms
- Replacing individual laminate planks
Key Takeaways
- Caulking laminate flooring gaps is not recommended as it can damage planks and cause bigger problems.
- Gaps are usually caused by seasonal expansion/contraction, uneven subfloors, or improper installation.
- Better solutions include using trim moldings, filler strips, replacing planks, or addressing subfloor issues.
- Leaving small gaps unfilled allows the laminate to move freely without buckling or warping.
- Caulk can restrict laminate’s natural movement, trapping moisture and dirt in gaps.

This table compares caulking laminate flooring gaps to recommended alternatives like trim, filler strips, and plank replacement. Caulking may be quick and easy but has significant downsides. The other options allow the flooring to move naturally while improving the appearance of gaps.
Caulking Laminate Flooring Gaps: The Verdict
Gaps between laminate flooring planks can be an annoying issue for homeowners. But reaching for the caulk to fill them in is not the best solution. Caulking restricts the flooring’s natural expansion and contraction, which can lead to damage over time. Trapped moisture and debris also create unsanitary conditions and odor issues.
For long-term solutions, address underlying subfloor problems or improper installation. Leave small gaps unfilled to allow movement. Use trim pieces, filler strips, plank replacement, or flooring transitions to improve the appearance of gaps while letting the laminate move freely. With some strategic work, you can remedy laminate flooring gaps without caulk.
Your laminate flooring will look great for years to come by avoiding caulk and giving it the space it needs. Keep an eye on manufacturer guidelines for humidity levels and seasonal movement. With reasonable preventive care and the right fixes, you can maintain gorgeous, gap-free laminate floors.
