The process of laying laminate flooring can seem straightforward, but there are many details to consider, from choosing the right underlayment to ensuring proper installation. One of these details often overlooked by DIYers is the necessity of leaving a gap around the perimeter of the laminate flooring. After all, laminate is often touted as being water-resistant, so what’s the big deal? During a recent home renovation project, I learned the hard way that neglecting this crucial step can lead to issues, including warped floors and even damage to the subfloor. As I struggled to fix the resulting problems, I realized that many others might be making the same mistake. This article will shed light on why leaving a gap around laminate flooring is essential and how it can save you headaches in the long run.

I’m sure you’ve heard the term “expansion gap.” But do you understand why it’s so important? Ultimately, it’s all about preventing laminate flooring from buckling, warping, and potentially damaging your subfloor. Laminate flooring, composed of layers of materials, including a core layer made from high-density fiberboard, is susceptible to changes in temperature and humidity. When exposed to fluctuating conditions, laminate expands and contracts slightly. This movement, often unseen by the eye, is a natural characteristic and a common phenomenon.
Expansion and Contraction – A Closer Look
Imagine a wall of tightly fitted laminate planks, with no room for expansion or contraction. As the temperature and humidity levels fluctuate, the laminate attempts to adjust. This pressure can build up, resulting in warped boards, unsightly gaps, and even damage to the subfloor. In essence, those tiny changes in flooring dimensions, over time, add up to significant problems in your home’s aesthetic and structural integrity.
However, if a gap is provided around the perimeter of the flooring, allowing the laminate to expand and contract freely, these problems can be avoided. The gap is typically measured a fraction of an inch, sometimes even as small as 1/8 inch, depending on the specific type of laminate flooring and the manufacturer’s guidelines. The space allows the flooring to naturally adjust to changes in the environment without putting pressure on itself or the subfloor.
The Right Way To Leave a Gap
Leaving room for expansion may seem like it’ll create an unattractive gap around your flooring, but there are ways to make the transition seamless. Consider using moldings, such as quarter-round or shoe molding, which provide a finish to the edge of the flooring and also conceal the expansion gap. There are moldings of various materials and styles available in the market, allowing you to find an option matching your flooring type and home décor
Expansion Gaps: A Deeper Dive
Expansion gaps are designed to account for the movement of laminate flooring throughout its lifespan. They prevent a phenomenon known as “cupping” or “bowing,” which occurs when laminate planks push against each other due to expansion. It results in a noticeable bulge in the floor’s surface, ruining the overall visual appeal.
Additionally, leaving a gap prevents moisture from escaping and getting trapped underneath the laminate, which can cause damage, mold growth, and other issues. Moisture is a major concern as it can seep under the flooring, triggering expansion and warping. This can lead to buckling and unevenness. A gap allows for air circulation, allowing any moisture that does seep in to dry out quickly.

Expert Advice and Tips for Success
While it might seem tempting to skip the gap, it’s an imperative step in ensuring a successful and long-lasting laminate floor. Here are some tips to keep in mind when planning your project:
- Check the manufacturer’s instructions: Always follow the manufacturer’s recommendations for expansion gaps. The amount of space needed varies between laminate flooring brands, and different types of laminate flooring require different gaps.
- Consider the environment: Where you live can also influence the size of the expansion gap required. Houses in humid climates or areas with significant temperature variations will need larger gaps to account for the greater expansion and contraction of the flooring.
- Use an expansion gap tool: For accuracy, consider investing in a tool to help you create a consistent expansion gap. These tools are usually inexpensive and readily available at home improvement stores or online.
- Plan for the expansion gap: Remember to factor in the expansion gap during the initial layout of the flooring. When securing the first row, leave enough space around the perimeter to account for the gap.
Frequently Asked Questions
Here are some of the most common questions about expansion gaps and laminate flooring:
- **Q: Do I need to leave a gap around all sides of the laminate flooring?**
<li>**A:** Yes, it’s essential to leave a gap around all four sides, including walls, cabinets, and other fixed objects. The expansion and contraction of the flooring applies to all sides and directions. </li>
<li>**Q: Can I fill in the expansion gap with caulk after the flooring is installed?**</li>
<li>**A:** It’s tempting but not recommended. Caulking the expansion gap prevents the flooring from moving naturally, defeating the purpose. Use molding to finish the edges for a more appealing look. </li>
<li>**Q: Can I use spacers to create the expansion gap?**</li>
<li> **A:** Spacers, especially plastic spacers, are generally not recommended. They are more likely to impede the natural expansion and contraction of the laminate. Use shims or a combination of wood spacers and shims to create a consistent gap.</li>
Do You Need To Leave A Gap Around Laminate Flooring
Conclusion
Leaving a gap around laminate flooring is essential for the longevity and integrity of your flooring. It might seem like a minor detail, but the impact of neglecting this step can lead to significant problems down the line, including costly repairs: warping, buckling, and even damage to the subfloor. It’s all about knowing why a gap should be left, how to create and maintain it, and choosing the right materials and techniques.
