What Causes Trapped Moisture in Wood Floor Planks?
Wood floor planks can develop trapped moisture due to several factors, which can cause issues like warping, cupping, or delamination. Here are some common causes:
Humidity
High humidity levels in the air can cause wood to absorb moisture. When the humidity drops, the wood can release the excess moisture, leading to trapped air bubbles. This can cause the wood to shrink, resulting in gaps and uneven floorboards.
Floor Finishing
Improper floor finishing can also contribute to trapped moisture. Using the wrong type of finish or applying it too thinly can leave residue on the surface, trapping moisture beneath. This can lead to issues like bubbling, blistering, or even rot.
Subfloor Issues
A subfloor that’s not properly prepared or is damaged can cause moisture to become trapped. For example, a subfloor with cracks or fissures can allow moisture to seep in and become trapped beneath the wood.
Climate
Extreme weather conditions, like flooding or high-temperature events, can cause sudden changes in humidity levels. This can cause wood to absorb or release moisture rapidly, leading to trapped air bubbles.
Poor Installation
Incorrect installation techniques, such as not spacing boards correctly or not allowing for proper drying time, can also lead to trapped moisture. This can cause the wood to absorb moisture unevenly, resulting in issues like cupping or warping.
Organic Matter
The presence of organic matter, like dirt, dust, or debris, under the wood floor can also contribute to trapped moisture. This can attract moisture and cause the wood to become damp or wet, leading to issues like warping or delamination.
Inefficient Ventilation
Poor ventilation in the building can also contribute to trapped moisture. When there’s poor airflow, moisture can become trapped, leading to issues like mold growth, warping, or delamination.
These are some common causes of trapped moisture in wood floor planks. By identifying and addressing these factors, homeowners and builders can take steps to prevent trapped moisture and ensure a healthy, durable wood floor.

What Are the Effects of Trapped Moisture on a Wood Floor, like Cupping and Buckling?
Wood floors can be prone to damage when moisture accumulates between the wood and the subfloor. This trapped moisture can lead to a range of issues, from cosmetic blemishes to structural concerns.
Cupping
Cupping occurs when the wood floor’s surface concaves, giving it a “cupped” appearance. This happens when the wood absorbs moisture from the subfloor, causing it to swell. As the wood dries, it contracts, pulling the boards upwards. Cupping can be particularly noticeable in areas where the humidity is high, such as near bathrooms or kitchens.
Buckling
Buckling occurs when the wood floor’s boards separate from the subfloor, creating a “buckled” or “wrinkled” appearance. This can happen when the moisture between the wood and subfloor is excessive, causing the wood to lift or warp. Buckling can be caused by a range of factors, including improper installation, poor subfloor preparation, or high humidity levels.
Other Effects
- Warped or twisted boards
- Cracks or splits in the wood
- Discoloration or staining
- Weakened floor structure
Addressing the Issue
- Proper installation and sealing of the wood floor
- Improved subfloor preparation
- Reducing humidity levels through ventilation or dehumidification
- Regular maintenance, including cleaning and drying of the floor
