What Causes Your Wood Doors to Expand and Swell?

Wood is a popular construction material in homes due to its natural beauty, warmth and elegance. However, under certain conditions and in specific times of the year, wood doors tend to swell and expand. This material is prone to becoming bigger in high humidity and smaller in dry air.

Discover what causes this problem to occur from a local provider of sliding windows and doors.

Why Wood Doors Swell and Expand?

The most common cause of expansion and swelling in wood doors is excessive moisture and insufficient water-repellent finish. When your door is properly sealed or finished, moisture can penetrate the material, especially on the bottom edge.

Where your home is located as well as the placement of your doors can also contribute to this problem. Doors in the southern and western areas get more sun exposure, which can harm their finish. They will start swelling in no time without the necessary protection.

What Can You Do About It?

One thing you can do to prevent this problem from occurring in residential windows and doors is by reducing your indoor humidity. If possible, open your windows and while cooking or showering. You should also turn on your exhaust fans.

Sometimes, refinishing the door is enough to fix the problem. However, always follow your manufacturer’s recommendation before accomplishing this task. Keep in mind that you may need to reapply these products regularly, especially on exterior doors. Another common way to prevent moisture and heat penetration is painting.
