As winter temperatures drop across the Midwest, home improvement company Wolf River Construction is advising homeowners and property managers to pay close attention to window performance during extreme cold. Drafty windows, condensation, and ice buildup can signal underlying problems that lead to higher energy bills, water damage, and long-term structural concerns if left unaddressed.

Why it matters

Windows are a common source of winter heat loss, and small gaps or failing seals can quickly turn into drafts, ice buildup, and moisture damage. These issues not only impact comfort and energy efficiency, but can also cause long-term damage to a home's structure if not properly addressed.

The details

Cold exterior air causes window frames and seals to shrink, creating gaps that allow cold drafts to enter the home. Warm, humid indoor air meeting cold glass can also cause condensation that may freeze, especially on older or single-pane windows. Ice buildup within window gaps can force seals to fail, allowing further air and moisture intrusion. Extreme temperature differences between indoor and outdoor environments can even cause window frames to warp or glass to crack.
