Signs Your Window Seals Have Failed

Any residential window contractor will tell you that windows require a certain level of attention to remain in good shape. In fact, even if you do maintain it on a regular basis, there’s a chance that your windows can still sustain certain kinds of damage, one of which is window seal failure. But how exactly can you tell if your window’s seals have failed?

Here are some of the signs you should look for:

You Feel a Draft

When it comes to windows, one of the signs that say its seals are broken is drafts. While this isn’t always the case, a window with a noticeable draft will need to be replaced with a better one eventually to prevent mold growth and high heating and cooling bills. However, just to be certain, don’t hesitate to ask a professional window installation company to inspect your windows first. That way, you can determine if broken seals really are the cause of the drafts.

Your Windows Are Foggy

From the moment your windows are installed, it’ll immediately go through a daily cycle of expansion and contraction due to thermal pumping. This puts pressure on seals, resulting in its eventual failure. When your seal fails, you can expect your windows to eventually become cloudy, with moisture finding its way between panes. As always, if it’s clear that your windows’ seals are broken, consider having a professional replace the seal or the windows entirely to prevent further problems in the long run.

"We recently replaced all of the windows in our home. I was most impressed with the friendly staff who knew what I wanted before I did. They seemed to be able to find the perfect window for each one we replaced. We are very pleased with the result. From beginning to end they were professional and helpful. I would highly recommend Renewal by Anderson."
