Windows are an essential part of our homes, providing light, ventilation, and a view of the outside world. However, when they start leaking, it can be a cause for concern. Understanding why windows leak and how to address the issue is crucial for maintaining the integrity and comfort of your home.

The Leading Cause: Improper Installation

Over 95% of window leaks can be attributed to improper installation. Surprisingly, in only a handful of cases is the actual window at fault. Most often, windows aren’t installed according to industry standards or best practices. While this might not be a problem in some regions, in areas like the Pacific Northwest, where homes face moisture for a significant part of the year, correct installation is paramount.

At KV Construction LLC, we prioritize proper window installation. We’ve witnessed the negative consequences of windows that were not correctly installed. Our team undergoes rigorous training to ensure that every window we install is leak-proof.

Which Windows Are Prone to Leaking?

While the question “Why are my windows leaking?” is common, it’s also essential to know which windows are most susceptible. Typically, older homes are more likely to have leaking windows. However, even newer homes in damp climates aren’t immune. Three primary factors contribute to window leaks:

  1. Poor Installation: This includes the use of subpar house wrap, failure to caulk the window flange, improperly installed or missing self-adhesive membrane, and other installation-related issues.
  2. Design Challenges: Some architectural designs, such as windows with minimal overhangs, windows near rooflines, or arched top windows, can be more prone to leaks.
  3. Lack of Maintenance: Regular maintenance, like cleaning out weep holes, replacing missing or cracked glazing, and ensuring window trim caulking is in good condition, can prevent leaks.
