What Causes Windows to Fail?

It’s frustrating when you notice that your home’s windows are no longer functioning properly. No one wants to look out their window and be unable to see through the glass because of a permanently foggy window or feel drafts on a cool fall night when the window is completely closed. So why do windows fail in the first place? Windows, like most man-made objects, don’t last forever. But there are several factors that can cause residential windows to fail prematurely and they can be broken down into three main categories:

  • The quality and materials of the original window
  • How the window was installed
  • How well the window has been cared for


The Quality of the Window

Window Seal Failure

Structural Failure

Use of Single Pane Glass

Lack of Low-e Coating

Hardware Failure

Failing Windows Summary

Purchasing quality windows made with superior materials to help keep your home secure and comfortable year-round, should be a major consideration instead of just price. Sure, cheap windows are less expensive up front, but you’ll end up replacing them decades sooner than quality-made windows. And you’ll more than likely end up paying more to heat and cool your home over time than if you were to purchase quality, energy-efficient windows, like Stanek Windows, in the beginning.
