Noticing gaps in your hardwood floors? You’re not alone! Over time, many homeowners find small spaces appearing between their floorboards. While some gaps are completely normal, others may need a little extra attention. Let’s break down the causes and solutions so you can keep your floors looking seamless and beautiful.

What’s Causing the Gaps?

Before jumping to a fix, it’s important to figure out why the gaps are appearing in the first place. Here are the two most common reasons:

• Seasonal Changes – Hardwood naturally expands and contracts with humidity and temperature shifts. In colder months, wood contracts, sometimes creating small gaps that close up again when the weather warms. If your gaps are seasonal, it’s best to wait before filling them.
• Installation Issues or Structural Changes – If the gaps are large and remain year-round, they could be due to improper installation, settling of the home, or excessive wear. In this case, you may need a more permanent solution.

How to Fill Small Gaps

If your hardwood floor is older and has minor gaps that don’t change with the seasons, you can use one of these simple fixes:

• Wood Floor Putty or Wood Filler – This is an easy, DIY-friendly option. Choose a filler that matches your floor color, apply it to the gaps with a putty knife, and wipe away any excess. Once dry, lightly sand if needed.
• Rope or Wood Strips – For wider, uniform gaps, some homeowners opt for jute rope or thin wood slivers. These can be glued into place and stained to match your flooring.

What to Do About Larger Gaps

If you have gaps that persist all year or are noticeably wide, a simple filler may not be enough.

Here’s what to consider:

• Board Replacement – If a single board has shrunk or shifted significantly, replacing it with a properly sized piece can solve the problem.

Preventing Gaps in Hardwood

To keep gaps from forming in the future, consider these preventative steps:

• Maintain Consistent Indoor Humidity – A humidifier in the winter can help prevent excessive wood contraction.
• Use Proper Installation Techniques – If you’re installing new floors, ensure proper acclimation and spacing for seasonal changes.
• Keep an Eye on High-Traffic Areas – Regular maintenance and inspections can catch potential issues before they worsen.

Final Thoughts

Gaps in hardwood flooring aren’t always a cause for concern, but knowing when and how to fix them for yourself or your clients is key. Whether you go for a quick solution or a more in-depth repair, addressing the problem early can help keep your floors looking great for years to come!
