Rotting windows can be a major issue for homeowners, particularly because they often go unnoticed until the damage is significant. Understanding the best and worst times to address rot repairs can help ensure that your home remains structurally sound and aesthetically pleasing.

The Best Time to Have Rot Repairs Done

After Winter, Preferably After a Few Hot Days

The ideal time to undertake rot repairs is after winter, once the weather has warmed up. This is because:

  • Moisture Reduction: During winter, windows often absorb a lot of moisture due to rain and snow. As temperatures rise, the moisture in the timber has a chance to evaporate.
  • Dry Conditions: A few hot days can help dry out the timber, making it easier to work with and less likely to harbor lingering moisture that can cause further rot.
  • Successful Repairs: Dry conditions ensure that repairs are more likely to be successful. Moisture can compromise the effectiveness of the repair materials and adhesives used, leading to potential failure down the line.

The Worst Time to Notice Rotting Windows

The most inconvenient and problematic time to discover rotting windows is during the winter. Here’s why:

  • High Moisture Levels: Winter is typically when windows are exposed to the most moisture from rain, snow, and condensation. This moisture can seep into the wood and exacerbate the rot.
  • Difficult Conditions for Repairs: Carrying out repairs in wet conditions is challenging. The moisture makes it difficult for repair materials to adhere properly, and working in cold, wet weather is less than ideal for contractors.
  • Continuous Damage: Moisture will continue to sit in the timber, causing ongoing damage until it’s removed or given an exit point. The wood remains vulnerable as long as it’s wet, leading to further deterioration.

Understanding Moisture Retention in Timber

Timber retains moisture for extended periods, especially if there’s no way for it to escape. Here’s what you need to know:

  • Prolonged Moisture: Moisture can stay trapped in timber until it’s physically removed or dried out by exposure to heat and airflow. Simply put, wet timber remains wet until it’s given a chance to dry.
  • Impact on Repairs: Attempting repairs on moist timber is likely to be less effective. The presence of moisture can prevent proper adhesion of repair materials, leading to suboptimal results.

Ensuring Effective Repairs

To ensure that your rot repairs are effective, consider the following tips:

  • Dry Conditions: Always aim to perform repairs in dry conditions. This increases the likelihood of successful adhesion and longevity of the repair.
  • Proper Paint Adhesion: After completing repairs, make sure to apply a good quality paint to seal the area. This prevents further water ingress and protects the wood from future damage.


The best time to address rot repairs is after winter, following a few hot days that help to dry out the timber. Noticing and attempting repairs during winter, when windows are most likely to leak and retain moisture, can complicate the process and lead to less effective repairs. Ensuring dry conditions and proper sealing with paint are crucial steps in maintaining the integrity and appearance of your windows.
