The Impact of Humidity on Hardwood Floors
When choosing the right flooring for your home, one of the first decisions you’ll face is whether to go with a hard surface or a soft surface. Both options have their unique benefits and drawbacks, making the choice dependent on your lifestyle, budget, and design preferences. In this blog, we’ll break down the pros and cons of each to help you make an informed decision.

Introduction
Hardwood flooring is a timeless choice for many homeowners in Searcy, offering both beauty and durability. However, hardwood is highly sensitive to humidity changes, which can cause expansion, contraction, warping, and gapping. Understanding how humidity affects your hardwood floors—and how to control it—can help protect your investment for years to come.
How Humidity Affects Hardwood Floors
Wood is a natural material that absorbs and releases moisture depending on the surrounding environment. This means that fluctuating humidity levels can cause significant changes in your hardwood flooring.
- High Humidity (Above 55%)
- During humid summer months, excessive moisture can cause hardwood planks to swell and expand.
- This can lead to buckling, warping, or cupping, where the edges of the planks rise while the center remains lower.
- If moisture remains trapped under the flooring, mold and mildew may develop.
- Low Humidity (Below 35%)
- In winter, indoor heating can dry out the air, causing hardwood floors to lose moisture and shrink.
- This can result in gaps forming between planks, making the floor look uneven and potentially leading to long-term damage.
How to Prevent Humidity-Related Hardwood Damage
Since humidity plays such a crucial role in the health of hardwood floors, homeowners should take steps to maintain stable humidity levels indoors.
- Use a Dehumidifier in Humid Months
- When the humidity is high, running a dehumidifier or using air conditioning can help maintain an optimal indoor environment.
- Keep indoor humidity levels between 35-55% to prevent excessive swelling.
- Use a Humidifier in Dry Months
- In winter, a humidifier can help add moisture back into the air and prevent hardwood from drying out.
- Maintaining proper humidity levels will reduce gaps and prevent wood from becoming brittle.
- Monitor Humidity Levels with a Hygrometer
- A hygrometer is an inexpensive tool that allows homeowners to measure indoor humidity levels.
- Place it in a central area of your home, especially if you have large sections of hardwood flooring.
- Use Rugs and Mats in High-Traffic Areas
- Placing rugs in entryways and high-traffic areas can help protect floors from excessive moisture, especially during rainy or snowy months.
- Avoid rubber-backed mats, as they can trap moisture underneath, leading to further damage.
- Ensure Proper Ventilation
- Good airflow helps maintain stable humidity levels.
- Open windows when weather permits, use ceiling fans, and ensure your HVAC system is well-maintained.
- Consider Engineered Hardwood for Humid Areas
- If you live in an area with high humidity fluctuations, engineered hardwood may be a better option than solid hardwood.
- Engineered wood has a layered construction that makes it more resistant to expansion and contraction.
