It is imperative that after you have installed your flooring that you maintain your humidity levels consistently throughout the year to reduce the amount of expansion and contraction that your floors will endure. Proper humidity levels should be between 35%-48%. To gage the humidity levels of your home, you can get a hygrometer, which is an instrument used to measure the moisture content of the atmosphere. We live in a country where we have extreme temperature variances. Temperature fluctuation will affect the humidity levels in your home. Excessive humidity can cause your floors to swell and cup. The proper way to maintain your humidity levels is to get a dehumidifier and run it at the proper settings. The air conditioner and heater can also be used to lower the humidity in your home. However, excessive dryness can cause your wood to shrink, which will create gaps between the boards. A humidifier can be used to maintain proper levels. It is beneficial to maintain a stable and structurally sound floor. Maintaining proper humidity levels in your home will extend the life of your hardwood, and keep your floors looking beautiful.
