Why are my wooden windows rotting?

Updated: Sep 20, 2023

There are several reasons why wooden windows may start to rot over time:

  1. Moisture: Exposure to moisture is one of the primary causes of wooden window rot. This can happen due to condensation, leaks, or humidity, which can cause the wood to absorb moisture and start to decay.

  2. Lack of maintenance: Wooden windows require regular maintenance to stay in good condition. If they are not properly sealed or painted, they can become more vulnerable to moisture and other forms of damage.

  3. Insect infestation: Insects like termites and carpenter ants can bore holes into wooden windows, causing damage that can lead to rot.

  4. Age: Wooden windows have a limited lifespan and may start to decay as they get older, especially if they have not been well-maintained.

To prevent your wooden windows from rotting, it's important to take steps to reduce moisture exposure, such as ensuring proper ventilation and fixing any leaks or condensation issues. Regular maintenance, such as painting and sealing, can also help protect the wood from damage. Additionally, you may want to consider replacing your wooden windows with newer, more durable materials like vinyl or fiberglass.
