It is a commonly known fact that water under your hardwood floors is a recipe for disaster. But, not very many people know that humidity can also affect your hardwood floors. Below, we provide you with some tips to help you keep your hardwood floors intact.

The Warning Signs in Winter

During the winter, the most common sign of humidity damage is gapping between the planks. When you turn your furnace on, the humidity level in your home decreases, which causes your wood to shrink. Your floors will not shrink in all directions, it is more common for them to shrink at the sides.

The Warning Signs in Summer

Humidity in the summertime will cause your wood floor to expand and press against one another. Like in the winter, they will swell up on the sides, and in some cases, the pressure will cause the boards to crack.

What Are The Ideal Humidity Levels?

It is recommended that indoor humidity rest anywhere between 35% to 55%.


Humidifiers are a great way for you to add humidity to the air while also giving you the ability to control and maintain it. Below are a few humidifier tips that will aid you in maintaining your floors.

Invest in a Hygrometer

A hygrometer is a device used for measuring humidity. With a hygrometer, you’ll be able to easily monitor the humidity levels in your home to ensure that it is always at an optimal level for your hardwood floors.

Get a Humidifier Installed In your HVAC System

A humidifier in your HVAC system will allow you to set the humidity levels in your home, instead of leaving it up to chance. This is a great option as it gives you the ease of controlling the humidity levels in your home, all year round. That means that the changing seasons won’t negatively impact your floors, as you will be able to adjust the humidity accordingly.

Consider a Portable Humidifier

While portable humidifiers are not as convenient and reliable as those built into your HVAC system, they are still better than not having anything to work with. You will have to monitor and clean-up moisture that may pool up around them, as well as refill them as recommended by the manufacturer’s instructions. It is recommended that you refill them using distilled water instead of tap water, which has minerals that can impact their efficiency.
