Did You Know?
1. The separation of hardwood floors is often caused by changes in humidity levels. Wood naturally absorbs and releases moisture, causing it to expand and contract. This process can lead to gaps appearing between the floorboards over time.
2. Some homeowners may be surprised to learn that excessive sunlight exposure can also cause hardwood floors to separate. Direct and prolonged exposure to UV rays can cause the wood to dry out and shrink, resulting in gaps between the boards.
3. In certain cases, the installation technique used for hardwood flooring can contribute to future separations. If the floorboards are not securely fastened together or the subfloor is not properly prepared before installation, gaps can occur.
4. Pets can unknowingly contribute to the separation of hardwood floors. The constant scratching by dogs or cats can wear down the finish and weaken the wood, making it more prone to separating over time.
5. The use of improper cleaning products or techniques can accelerate the separation of hardwood floors. Cleaning agents that contain harsh chemicals or excessive amounts of water can cause the wood to swell or warp, leading to gaps between the floorboards.
Common Causes Of Gaps In Hardwood Floors
Hardwood floors are known for their timeless beauty and durability, but like any natural product, they are not immune to imperfections and changes over time. One common and frustrating issue that many homeowners face is the separation or gapping of hardwood floors. These gaps can appear more frequently during the winter months, leaving homeowners wondering why their pristine floors are suddenly showing signs of distress.
The main cause of gaps in hardwood floors is the natural movement of the wood itself. Wood is a hygroscopic material, meaning it absorbs and releases moisture in response to changes in humidity levels. As the moisture content in the wood fluctuates, it can cause the boards to expand or contract, leading to gaps between them. Additionally, wood is not a perfect material, and even during the manufacturing process, slight variations in size and shape can occur, contributing to gaps over time.
Factors such as the location of the hardwood floors within the home can also play a role in the appearance of gaps. Areas with high humidity, such as kitchens or bathrooms, are more susceptible to gaps due to the increased moisture content in the air. As the wood absorbs moisture, it swells, and when the moisture levels decrease, it shrinks, resulting in the formation of gaps.
Impact Of Humidity On Hardwood Floor Separation
Humidity levels significantly impact the separation of hardwood floors. In regions with extreme climate variations, such as cold winters and hot summers, humidity fluctuations are more pronounced and result in larger gaps. During winter, indoor heating systems are commonly used, which dries the air and causes the wood to lose moisture, leading to shrinkage and the formation of gaps between floorboards.
On the other hand, high humidity levels can also contribute to floor separation. Excessive moisture in the air causes the wood to absorb water, leading to expansion of the floorboards. When humidity levels decrease, either due to a change in season or the use of air conditioning systems, the wood releases moisture and shrinks, creating gaps between the boards.
To prevent or minimize gaps caused by humidity, it is essential to maintain a stable indoor environment. Using a humidifier during the winter months adds moisture to the air and prevents excessive drying of the wood. Additionally, keeping humidity within the recommended range of 35-55% ensures the longevity of hardwood floors and reduces the likelihood of separation.
Importance Of Proper Installation In Gap Prevention
While wood flooring separation is a natural process, proper installation techniques can significantly reduce the likelihood and severity of gaps. Hiring a professional installer who has experience working with hardwood floors is crucial to ensuring the floors are installed correctly.
During the installation process, an experienced installer will take into account factors such as the subfloor condition, moisture levels, and acclimation of the wood to the environment. These considerations are essential to prevent the wood from expanding or contracting excessively, which can lead to gaps. Additionally, professional installers will ensure that the flooring is properly secured to the subfloor, minimizing movement and the potential for gaps to form.
It is important to note that if hardwood floors were not installed correctly, gaps may appear even during periods of low humidity. Poor installation can result in inadequate expansion gaps, improper acclimation of the wood, or failure to use the appropriate installation methods. In such cases, professional advice should be sought to assess the situation and determine the best course of action to minimize gaps and ensure the safety and integrity of the hardwood floors.
Addressing Gaps In Hardwood Floors Promptly
When gaps begin to appear in hardwood floors, it is crucial to take prompt action to address the issue. Ignoring the problem can lead to further damage and potentially compromise the stability of the flooring.
The first step in addressing gaps is to identify the cause. If the gaps are a result of natural movement due to seasonal changes or fluctuations in humidity levels, simple fixes may be sufficient. Using a high-quality wood filler suitable for hardwood floors, carefully fill the gaps, ensuring the filler is evenly distributed and level with the surrounding floorboards. Once the filler has dried, the floors can be sanded and refinished to restore their original appearance.
For more extensive gaps or gaps caused by poor installation or aging, seeking professional advice is recommended. In some cases, the entire hardwood floor may need to be replaced, especially if the gaps are widespread or severe. A professional flooring contractor can assess the situation, identify the underlying issues, and recommend the most appropriate course of action to restore the floors to their original beauty.
- Identify the cause: natural movement or poor installation.
- Simple fixes for gaps caused by natural movement: use high-quality wood filler, sand, and refinish.
- Seek professional advice for extensive gaps or gaps caused by poor installation or aging.
- Replace the entire hardwood floor if gaps are widespread or severe.
- Consult a professional flooring contractor for an assessment and recommendation.
Seasonal And Temperature Factors In Floor Separation
Seasonal and temperature changes significantly impact the appearance and severity of gaps in hardwood floors. During the winter months, when humidity levels are low and indoor heating is used, the wood can lose moisture and shrink, resulting in gaps. To minimize this issue, it is recommended to maintain a home temperature between 65-77 degrees Fahrenheit in winter, as this range helps minimize the drying effect on hardwood floors.
On the other hand, during the summer months, when humidity levels are high and air conditioning systems are used, the wood can absorb moisture and expand, leading to gaps. To prevent excessive swelling and reduce the occurrence of gaps, using a dehumidifier in the summer can help remove excess moisture from the air.
It’s important to note that while seasonal and temperature changes can contribute to gaps in hardwood floors, these gaps are usually temporary and may close up as the wood adjusts to the new environment. However, if the gaps persist or become more severe over time, it may indicate an underlying issue that requires professional attention.
- To minimize gaps in hardwood floors during winter, maintain a home temperature between 65-77 degrees Fahrenheit.
- Use a dehumidifier in summer to remove excess moisture from the air and reduce the occurrence of gaps.

Ways To Fix And Prevent Wood Flooring Separation
When addressing wood flooring separation, several methods can be employed to both fix existing gaps and prevent new ones from forming.
-
For minor gaps, where the separation is less than 1/8 inch, filler can be used to fill the gaps and create a seamless look. The filler should be specially formulated for hardwood floors and applied carefully, ensuring it is evenly distributed and level with the surrounding floorboards. Once the filler has dried, the floor can be sanded and refinished to restore its original appearance.
-
For larger gaps or gaps caused by excessive wood movement, wooden pegs or splines can be inserted into the gaps between the floorboards to stabilize them and prevent further separation. This technique can help maintain the alignment and spacing of the boards and provide a long-term solution for preventing future gaps.
Another crucial aspect of preventing wood flooring separation is to maintain an optimal moisture balance in the home. As mentioned earlier, using a humidifier during the winter months can help add moisture to the air and prevent excessive drying of the wood. Conversely, using a dehumidifier during the summer can help remove excess moisture and prevent the wood from swelling and causing gaps.
In cases where gaps are extensive or the underlying issues are complex, it is recommended to consult a professional flooring contractor. They can assess the situation, identify any structural or installation-related issues, and provide expert advice on the best course of action. In some instances, replacing the entire hardwood floor may be necessary, especially if the gaps are severe or widespread.
