Although it’s not a common occurrence, you can expect window seal failure to happen to your windows after a few years due to natural deterioration. However, this can happen sooner if you don’t maintain your windows regularly, so be sure to check and clean your windows every once in a while.

If you’re already noticing some sort of distortion on your windows, then there’s a chance that seal failure has occurred. You may also need to have it checked and repaired by your trusted new window installation contractor.
How Window Seals Work
Many of the windows available on the market are built with two or three layers of glass sandwiched together. They’re assembled and separated by either an air vacuum or filled with inert gases such as krypton or argon, turning them into what’s called insulated glass units or IGUs. These are typically coated with a heat-reflective low-emissivity material to slow energy transfer and keep the indoor temperatures of your home comfortable no matter what the season.
How to Check for Broken Seals
Checking your windows for failed or broken seals start with cleaning them inside and out so you can be sure that you’re not just looking at grime and moisture. Afterward, you need to stand a couple of feet from the windows and look closely at your reflection. If you notice some distortion compared to your other windows, then there’s a chance that the inert gas has leaked and the panes have slightly bent or collapsed towards the center.
Sometimes, windows can experience seal failure even after a recent installation. For instance, it can fail due to high altitudes and sudden changes in atmospheric pressure. To avoid this, manufacturers would maintain regional factories where windows are made and installed in conditions that are ideal to the local atmosphere.
You can always have your seals routinely checked by a professional, but if you’re already noticing this on your windows, then a replacement is needed as soon as possible.
