Top 4 Causes of Window Failure and Ways to Address Them

Windows can be a costly purchase, so it makes sense to prolong their service lives as much as you can. This goal is only attainable if you’re aware of the usual causes of window failure.

Today, Renewal by Andersen® of Milwaukee talks about the common reasons why casement, double-hung, bay, bow, sliding and picture windows fail.

1. Decay

Wood windows are susceptible to rot. The deterioration of timber always starts with exposure to moisture. The presence of water allows fungus to grow and consume everything that makes wood strong and reliable as a construction material.

The rate of wood deterioration increases with poor ventilation. The inability of your home to expel moisture-ridden inside air is bad news for your windows.

Although you don’t necessarily need to replace the rotten wood components, restoring the damaged areas will only address the symptom. A more cost-effective and better long-term solution is to buy moisture-resistant replacement windows.

2. Deformation

Vinyl windows are notorious for warping or bowing due to severe thermal expansion. You may be able to reduce their chances of deformation by protecting them from direct sun exposure with shade, but this strategy isn’t always feasible.

To prevent structural damage because of frame and sash deformation, choose Renewal by Andersen of Milwaukee’s Fibrex® material that’s on par with wood’s rigidity.

3. Interior Condensation

The moment your double-pane windows sweat inside signifies seal failure. It signals that moisture can now get into the space between the layers of glass and the insulating gas fill is leaking. In many cases, drafts can also infiltrate through the gaps.

There’s no way to fix interior condensation problems but to replace the problem units. Otherwise, you are likely to experience discomfort and pay for higher energy costs sooner than later.

4. Operational Dysfunction

The balance mechanism of old-fashioned sash windows can fail, causing the raised panel to slam shut. Buying modern double-hung window systems is more viable than retrofitting your dated units with modern hardware.
