Hardwood flooring is renowned for its timeless elegance, durability, and warmth it brings to any space. However, its performance can be significantly influenced by environmental factors, with humidity playing a pivotal role. Understanding how humidity affects hardwood flooring is crucial for maintaining its beauty and longevity. With this mind, we at Mike’s Custom Flooring would like to discuss the impact of humidity on hardwood flooring.
What is an Acceptable Humidity Moisture Reading in Hardwood Floors?
1) Hardwood Flooring Expansion & Contraction: One of the most significant ways humidity impacts hardwood flooring is through the natural process of expansion and contraction. Wood is hygroscopic, meaning it absorbs and releases moisture based on the surrounding humidity levels. In high humidity, wood absorbs moisture and expands, while in low humidity, it releases moisture and contracts. This constant movement can lead to issues such as cupping, crowning, and gapping.
2) Cupping & Crowning of Hardwood Floors: Cupping occurs when the edges of hardwood planks are higher than the center, forming a concave shape. This is often a result of excessive moisture absorption, causing the edges to expand more than the center. Conversely, crowning happens when the center of the plank is higher than the edges due to moisture loss. Both cupping and crowning can create uneven surfaces and compromise the aesthetic appeal of the hardwood floor.
3) Hardwood Floor Gapping: Gaps between hardwood planks can develop when the wood contracts during periods of low humidity. While some degree of gapping is normal, extreme gaps can be unsightly and may indicate a humidity imbalance. Maintaining a stable indoor humidity level is crucial to minimizing the risk of excessive gapping.
4) Buckling of Hardwood Flooring: In extreme cases of high humidity, hardwood floors may buckle. Buckling occurs when the wood swells beyond its capacity, causing the planks to lift from the subfloor. This not only damages the floor but also poses safety risks. Proper humidity control is essential to prevent such severe issues.
5) Hardwood Flooring Finish Damage: Humidity fluctuations can also impact the finish on hardwood floors. In high humidity, finishes may take longer to cure, leading to a prolonged drying process. Conversely, low humidity can cause finishes to dry too quickly, resulting in a compromised appearance. Maintaining consistent humidity levels ensures the proper curing and longevity of the finish.
6) Prevention & Maintenance of Hardwood Floors: To mitigate the effects of humidity on hardwood flooring, it’s essential to implement preventive measures and proper maintenance. Using a dehumidifier in humid climates or during wet seasons can help control indoor humidity levels. Conversely, employing a humidifier in dry climates or during the winter months can prevent excessive moisture loss.

Regularly monitoring and adjusting indoor humidity levels, especially during seasonal changes, is crucial. Additionally, acclimating hardwood flooring to its environment before installation helps minimize the risk of post-installation issues related to humidity.
In general, humidity significantly impacts hardwood flooring, influencing its dimensional stability, appearance, and overall performance. By understanding these effects and implementing preventive measures, homeowners can ensure the longevity and beauty of their hardwood floors, preserving the timeless appeal that hardwood brings to any space.
