5 Common Causes of Window Seal Failure

Windows are crucial to maintaining your home’s energy efficiency, comfort and aesthetic appeal. They also allow you to capture captivating outdoor views. However, their seals can deteriorate over time, leading to various issues, including drafts, leaks and increased energy costs. 

Here are five of the most typical reasons window seals fail. 

1. Poor Installation 

Improper installation is one of the most common causes of window seal failure. Gaps can form around poorly secured units, compromising their seals’ integrity. You can avoid this problem by hiring reputable professionals. 

2. Normal Aging and Wear

Like all building components, windows won’t last forever. It’s normal for window seals to degrade over the years due to exposure to UV rays, moisture, temperature fluctuations and other outdoor elements. Harsh weather conditions can also accelerate the deterioration of windows. If your windows are over a decade old and in poor condition, replacing them might be more reasonable and economical.

3. Temperature Fluctuations

Window materials can expand and contract due to extreme temperature changes. Constant thermal movement can strain the seals, eventually causing them to crack. Units with failed seals will lose their insulating properties and develop fogging between panes. Besides compromising your comfort, they can harm your home’s curb appeal. 

4. Excessive Moisture Damage

Excessive moisture from rain, snow and humidity can also contribute to window seal failure. Wooden frames are more susceptible to rot and mold, weakening the seal. Choosing windows with materials highly resistant to moisture can mitigate these risks. 

5. Design Flaws 

Sometimes, seal failures occur due to design flaws with windows or inferior materials. Units with manufacturing defects or made from substandard materials might need replacement early. High-quality windows from reputable manufacturers are usually more durable, energy-efficient and longer-lasting. They also often come with comprehensive warranties, protecting your investment.
