Seal failure is a serious problem for residential windows. In most cases, this issue requires window replacement. Read on as we discuss the common causes of window seal failures.
If the window seal fails shortly after your windows were installed, then it’s likely the installation was botched. Your contractors may have damaged the seal during the installation process, the seal used may have been defective, or it may not have been given enough time to set. You’ll need to call your window contractor and ask them to re-install the window to rectify this problem.
Fluctuating temperatures can cause your window seal to fail eventually. This is because prolonged exposure to extreme hot or cold temperatures can cause the window seal to shrink, crack or sag, compromising the windows’ weatherproofing capabilities. A professional can apply another batch of sealant to your windows if this happens.
As a homeowner, it’s your responsibility to maintain your sliding or double-hung windows. Otherwise, your windows may fail earlier than expected. By properly maintaining your windows, you can easily avoid window seal failure, ensuring that your windows remain as energy-efficient as possible.
If your windows are over 20 years old, seal failure is more likely to occur. When this happens, it means the unit is at the end of its lifespan and will need to be replaced.
