Understanding Gaps in Wooden Floors and How to Address Them
You spent a lot of time and effort choosing the perfect flooring to suit your needs and complement your home’s style. Naturally, it can be disappointing to discover gaps forming in your hardwood floors. Even if your floors were installed tightly and professionally, it’s important to remember that wood is a 100% natural product, and its behavior depends on environmental conditions.
Why Do Gaps Form in Hardwood Floors?
Gaps in wooden floors are a natural occurrence caused by the wood’s expansion and contraction in response to changes in moisture levels. While some gaps are normal, others can be a cause for concern.
Types of Gaps in Wooden Floors
- Natural Gaps:
- Small gaps allow for the wood to expand and contract, preventing buckling or damage.
- Large rooms or spaces over 100 sq. meters often require additional gaps to manage the natural movement of the wood.
- Deliberate Gaps:
- Certain designs, like rustic or aged floors, may include gaps for aesthetic purposes.
- Problematic Gaps:
- Poor installation or subpar materials can cause significant gaps that compromise the floor’s appearance and integrity.
- Underfloor heating or wet subfloors can also lead to shrinkage or warping.

Factors That Influence Gaps
- Wood Species:
Exotic woods like Ipe or Sucupira resist moisture changes better, while pine floors are more prone to gaps, especially on ground floors. - Room Environment:
Fluctuations in temperature and humidity can amplify the appearance of gaps.
Professional Installation and Maintenance Matter
Choosing the right craftsmen and high-quality materials is key to minimizing unnecessary gaps. Professional installers ensure that your floor is prepared with appropriate expansion gaps and that subfloor conditions are optimal to prevent future issues.
Fixing Existing Gaps
For small gaps, pine slivers—wedges of reclaimed wood—can be used to fill spaces, offering a seamless and professional finish. However, some gaps, like those in pine floors, should be left unfilled to accommodate future movement.
