Are Your Window Seals Showing Signs of Failure?

One of the leading causes of window failure is a broken seal. This is true for any style of window, from sliding windows to picture windows.

Over time, the seal on a window can wear out, causing problems. Today, Renewal by Andersen® of San Antonio shares the signs of a broken seal.

Regular Wear and Tear

The quality of the window installation depends on the skill of your contractor. However, even a high-quality window that’s perfectly installed will experience wear and tear over the years. Even with a proper seal, the inert gas between the window panes can still escape at a rate of 1% every year. If you take a look at your bill and notice that it’s gradually increasing compared to last year, it’s a sign that your window seals may have started to deteriorate.

Condensation Problems

Another sign that your window seals are beginning to fail is sporadic condensation problems. Double-pane windows are designed to prevent condensation problems, so if you see water droplets on the inside or outside of any windows in your home, call your window contractor for an inspection of your seals.

Repair or Replace?

In some styles of windows such as a bay window, installing a replacement can be challenging. If your windows are in the early stages of seal failure, you may be able to simply replace the glass. However, for older windows with advanced seal failure, it may be time to consider getting a full replacement.

"If I could heap more praise on Renewal by Andersen, I would have to buy a dump truck. They recently replaced 13 doors in my home in an exemplary fashion. Very professional, efficient and, in my estimation, worth every penny."
