5 Common Ways Window Seals Fail

Maintaining the integrity of your windows is crucial not only for the aesthetic appeal of your home but also for energy efficiency and comfort. Windows are your home’s eyes to the outside world and your shield against the elements. However, window seals, pivotal in keeping your windows effective, can and do fail for various reasons. Learn five of the most common reasons behind window seal failure in this post.

1. Temperature Fluctuations and Weather Extremes

Frequent changes in temperature can cause window seal materials to expand and contract. This constant cycle gradually weakens the seals, leading to failure. Weather extremes, such as high winds and hail, can also physically damage the seals, worsening the issue.

2. Poor Installation and Product Quality

The longevity of your window seals heavily depends on the quality of the installation and the materials used. Incorrect installation can create gaps in the sealant, while low-quality materials may not stand up to the test of time or environmental stress, resulting in premature failure.

3. Physical Damage and Natural Wear and Tear

Physical impacts—whether from routine maintenance, children’s activities, or accidents—can cause immediate seal failures. Over time, natural wear and tear further degrade the elasticity and effectiveness of the seals, making them more prone to damage.

4. Moisture and Water Damage

Moisture is a window seal’s worst enemy. Snow, rain, and humidity can all lead to moisture buildup around window frames. This moisture can seep into the sealant, reducing its adhesive properties. Freezing and expansion during cold weather can also cause seals to crack and fail.

5. Improper Maintenance

Regular maintenance is essential for extending the life of your window seals. Neglecting tasks like cleaning windows and seals can lead to a buildup of dirt and grime, which hardens over time and puts stress on the seals. Removing snow and ice from window frames is particularly important to prevent moisture penetration and damage from freezing.
