Winter in New Jersey is beautiful but challenging, especially when it comes to maintaining your floors. One common issue homeowners face during the colder months is floor gapping—unsightly gaps that appear between floorboards. These gaps not only detract from the appearance of your flooring but can also lead to long-term damage if left unaddressed.
Understanding why floor gapping occurs and implementing preventive measures can save you time, money, and frustration. Here’s how you can protect your floors and keep them looking their best this winter.
What causes floor gapping?
Floor gapping is primarily caused by changes in humidity and temperature. During New Jersey winters, the air becomes dry due to heating systems and lower outdoor humidity levels. This dry air pulls moisture out of your wooden floors, causing them to shrink and create gaps.
While hardwood floors are more susceptible to gapping, engineered wood and laminate floors can also experience this issue under extreme conditions.
The impact of humidity on flooring
Wood is a natural material that reacts to its environment. When humidity levels drop, the lack of moisture causes wood to contract. Conversely, high humidity levels in summer make the wood expand. This constant cycle of expansion and contraction can weaken your flooring over time, making floor gapping a recurring problem.
Tips to prevent floor gapping
1. Maintain consistent indoor humidity levels
The key to preventing floor gapping is stabilizing the humidity in your home. Aim to keep indoor humidity levels between 35% and 55%. You can achieve this by:
- Using a humidifier: A whole-house humidifier or portable unit can add moisture to the air during winter.
- Sealing drafts: Prevent cold, dry air from entering your home by sealing windows, doors, and any other gaps.
- Monitoring humidity: Invest in a hygrometer to regularly check your home’s humidity levels.
2. Allow for proper acclimation before installation
If you’re installing new floors, ensure that the material is acclimated to your home’s environment. Store the flooring materials in the room where they will be installed for at least 3-5 days. This step allows the wood to adjust to the ambient temperature and humidity, minimizing future shrinkage or expansion.
3. Opt for wider planks with seasonal gaps in mind
Wider planks tend to show more noticeable gapping during the winter. If you’re concerned about aesthetics, consider narrower planks, which make gaps less obvious. You can also choose flooring materials with built-in flexibility, such as engineered wood, to reduce the chances of visible gaps. Mirage Tru-Balance engineered floors allow for 25 to 80% relative humidity making it much easier to maintain appropriate humidity levels.
4. Control your home’s temperature
Drastic temperature changes can exacerbate floor gapping. Avoid setting your thermostat too low at night or when you’re away from home. Instead, maintain a consistent indoor temperature to ensure the wood doesn’t expand or contract too quickly.

If you notice minor gapping, it may resolve itself when humidity levels rise in spring and summer. However, larger or persistent gaps may require professional attention. The team at Floors by The Shore specializes in repairing and restoring gapped floors, ensuring they look as good as new.
