Humidity and Hardwood Floors: The Impact on Appearance and Wood Integrity

Updated: Jul 14, 2023

Greetings, hardwood floor enthusiasts! I'm Jayce Espinosa, owner of Espinosa Hardwood Floors, and today we're diving into the crucial topic of humidity and its effects on newly installed hardwood floors. Understanding how humidity levels can influence the appearance and integrity of your wood planks is essential for maintaining the long-lasting beauty and functionality of your floors. Let's explore this important aspect together!

The Battle of Moisture and Hardwood Floors:

Humidity, the presence of moisture in the air, can significantly impact hardwood floors, especially during and after installation. Here's what you need to know:

Expansion and Contraction: Hardwood is a natural material that absorbs and releases moisture according to its environment. High humidity levels cause wood to absorb moisture, leading to expansion. Conversely, low humidity levels can cause wood to lose moisture, resulting in contraction. These fluctuations can cause the wood planks to shift, buckle, or develop gaps, compromising both the appearance and structural integrity of your hardwood floors.

Cupping and Crowning: When exposed to excessive water or moisture, hardwood planks may experience cupping, where the edges of the planks are higher than the center, creating a concave shape. On the other hand, in drier conditions, crowning occurs, with the center of the planks rising above the edges. These issues not only impact the aesthetics but can also lead to potential tripping hazards and an uneven floor surface.

Prevention and Maintenance:

To ensure your hardwood floors remain in optimal condition, it's vital to take preventive measures and establish a maintenance routine that considers humidity levels:

Acclimation: Before installing hardwood floors, it's crucial to acclimate the wood planks to the environment where they will be installed. This process allows the wood to adjust and reach an equilibrium with the moisture content of the space. Proper acclimation minimizes the potential for excessive expansion or contraction after installation.

Moisture Monitoring: Invest in a reliable hygrometer to measure and monitor the humidity levels in your home. Ideally, humidity should be maintained within a range of 35% to 55% for hardwood floors. Using humidifiers or dehumidifiers, as needed, helps stabilize the moisture levels and reduce the risk of damage to the wood.

Regular Cleaning and Maintenance: Implement a regular cleaning routine that involves dry or slightly damp mopping to remove dirt and spills promptly. Avoid excessive moisture when cleaning, as standing water or excessive dampness can seep into the wood and cause swelling or damage.

Protective Measures: Consider using area rugs or floor mats in high-traffic areas or areas prone to moisture, such as entryways and kitchens. These provide an extra layer of protection against potential water damage and reduce the direct impact of humidity on the wood.

Professional Guidance:

When it comes to hardwood floors and humidity, seeking professional guidance is invaluable. Trained hardwood floor installers and experts, like us at Espinosa Hardwood Floors, can assess your specific environment, recommend suitable flooring options, and provide maintenance advice to safeguard your investment.


Humidity is a significant factor that can affect the appearance, stability, and longevity of your hardwood floors. By understanding the impact of moisture on wood planks and implementing preventive measures, you can maintain the beauty and structural integrity of your floors for years to come. Remember, Espinosa Hardwood Floors is here to provide expert guidance and support in preserving the natural elegance of your hardwood flooring.
