Why Do Some Replacement Windows Fail Early?

You make a significant financial commitment when you upgrade your home exterior. You expect your new windows to provide energy efficiency and curb appeal for decades, which makes it incredibly frustrating when they begin to fog up, draft or leak after only a few years.

Why does this happen? At Berg Home Improvements, we have served homeowners throughout Illinois for over 50 years. We have seen firsthand that premium glass means nothing without the right handling. The main culprits for premature window failure often boil down to:

• Improper installation techniques
• Compromised or poor sealing
• Incompatible or low-quality materials
• Unchecked moisture intrusion

If you want to protect your investment, it’s important to understand how these factors can significantly shorten the lifespan of your windows.

What Are Common Window Installation Issues?

The most common reason for early failure is human error. Windows must be perfectly square, level and plumb within the opening. If an inexperienced contractor rushes the job or mismeasures the rough opening, the window frame will experience uneven stress that can cause the unit to warp over time. When the frame twists, the glass seal often breaks. You need a team with a proven track record to ensure your new window is installed with precision.

How Does Poor Sealing Impact Windows?

The seal around your window is its primary defense against the elements. If the weatherstripping is defective or the perimeter caulking is applied unevenly, air infiltrates your home. However, this damage often goes deeper than just air leaks. Thermal stress from fluctuating temperatures can crack weak seals, leading to the release of gases from insulated windowpanes. This leads to that unsightly fog or condensation between the panes that cannot be wiped away.

What Happens If The Wrong Materials Are Used?

Not all construction materials play nicely together. Using the wrong adhesive or sealant can lead to a chemical reaction that may compromise waterproofing barriers. Additionally, choosing the cheapest vinyl option can backfire in the end. Low-quality materials may become brittle and crack during freezing winters or warp in the summer sun. You need materials that are compatible with your specific home exterior and proven to withstand the local climate.

How Can Moisture Make Windows Fail Faster?

Over time, leaks in your window or its frame can allow moisture to seep in, causing serious damage. Water entering through gaps or cracks can get trapped behind the siding with no way to escape. This trapped moisture can lead to rotting wood around the window frame, compromising the entire structure. Decaying wood may cause the frame to shift, which in turn can break the glass seal and make the problem even worse. Proper flashing installation and window sealing are essential for directing water out and away from the wall cavity.
