What Causes Gaps in Hardwood Floors and How to Fix Them
Hardwood floors add warmth and elegance to any home, but they’re not without their challenges. One common issue many homeowners face is the appearance of gaps between the floorboards. These gaps can disrupt the beauty of your floors and even lead to bigger problems if not addressed. In this blog, we’ll discuss the common causes of hardwood floor gaps and practical solutions to fix them, helping you maintain a stunning and durable floor.
What Causes Gaps in Hardwood Floors?
1. Seasonal Changes
Hardwood is a natural material that expands and contracts with changes in humidity and temperature. During the winter months, when indoor heating is high and the air is dry, hardwood boards may shrink, causing gaps to appear. In contrast, summer’s humidity can make the boards swell.

2. Improper Installation
If the floorboards were not acclimated to your home’s environment before installation, they might not settle properly, leading to gaps over time. Additionally, incorrect spacing during installation can exacerbate the issue.
3. Moisture Imbalance
Moisture levels play a significant role in maintaining the stability of hardwood floors. Excess moisture can lead to warping and shrinkage, while insufficient moisture can cause the boards to pull apart. To prevent moisture-related problems, follow these tips on preventing and repairing hardwood floor warping.
4. Sunlight Exposure
Prolonged exposure to sunlight can dry out hardwood floors, causing them to shrink and develop gaps. This issue is particularly common in rooms with large windows or skylights. For advice on protecting your floors from UV damage, check out this guide.
How to Fix Gaps in Hardwood Floors
1. Humidity Control
Maintaining a consistent indoor humidity level (between 30-50%) is key to minimizing gaps. Using a humidifier in winter and a dehumidifier in summer can help keep your hardwood floors stable.
2. Filling Small Gaps
For minor gaps, wood filler or putty can be used to fill the spaces. Choose a color that matches your flooring to ensure a seamless look. This method works best for aesthetic fixes rather than structural issues.
3. Installing Flexible Fillers
Flexible fillers are designed to move with the wood as it expands and contracts. These are ideal for areas with frequent seasonal changes.
4. Replacing Damaged Boards
In cases where gaps are caused by damaged or warped boards, replacing individual planks may be the best solution. Learn how to ensure new boards match the existing floor by visiting this resource.
5. Refinishing the Floor
Refinishing can address larger issues and restore the overall appearance of your floor. Consider whether an oil-based or water-based finish is better suited for your needs before starting the process.
Preventing Gaps in the Future
- Acclimate Flooring Before Installation: Allow hardwood planks to adjust to your home’s environment for several days before installation.
- Use Wide or Narrow Planks Strategically: Depending on your region’s climate, you may benefit from wide vs. narrow planks to minimize visible gaps.
- Protect Floors from Sunlight: Use window treatments or UV-blocking films to reduce sunlight exposure.
- Regular Maintenance: Periodically clean and inspect your floors to catch and address small issues before they worsen.
Gaps in hardwood floors may seem like a daunting issue, but with proper care and maintenance, you can restore their beauty and longevity. Understanding the causes of these gaps and applying the right solutions ensures your hardwood floors remain a timeless feature in your home. By taking preventative measures and addressing problems early, you can enjoy the elegance and warmth of hardwood flooring for years to come.
