How to Spot a Failing Window Seal - Our Guide
Advanced Exteriors MN
Most older homes will have windows with single-pane glass, whereas newer homes will feature insulated windows. Such windows are also known as insulated glass or thermopanes. Seals on these windows may fail over time as the gas between the units leaks out and moisture enters the space between the panes.
Seals might fail due to the air outside and the gas inside the panes naturally escaping. This can happen at a faster rate if the insulated glass is poorly made, but it can also happen even if it is perfectly made. Here's how glass seals fail:
Failure
Insulated glass windows will gradually experience seal failure over the years after installation. In order to avoid seal failure, you should make sure that you keep the glass panes installed in approximately the same conditions they were manufactured under. When the glass is transported, the seals could even fail early due to atmospheric pressure.
Keeping it clean
Keeping the glass clean is important for detecting any visual signs of failure in the sealant. You should make sure your windows are as clean as possible so that you can see clearly from both sides of the window. You should be looking for any moisture and grime between or through the glass.
Distortion
When the inert gas starts to leak out of the insulated glass, the window panes may begin to bend and warp slightly in the center, which might cause the glass to look distorted. If you see that the glass in one window is more distorted than those in the other windows of your home, the one with distorted glass might have a failed seal.
Sporadic condensation
Any fog, haze or moisture between two panes of glass is usually a telltale sign of a failed seal. Condensation between the panes is more likely to occur when the indoor and outdoor temperatures are drastically different. You might see a change in condensation as temperatures change, so just keep a close eye on it.
Dealing with it
There are some things that you can do to fix a failed seal including getting your windows defogged or replacing the window completely. Defogging your window can be done with the help of a defogging company. What they will do is drill a tiny hole in the glass, expel the condensation and install a valve along with a new seal. Removing the fog and condensation can keep the window looking good as new, but only for a limited amount of time. Your best bet is to get it completely replaced by a professional window replacement company. Removing damaged windows and replacing them with completely new ones means you will be able to enjoy windows with a longer lifespan.
Hiring a professional
When you are searching for someone to replace your windows, you should do your research carefully. Check out their website, make calls, and go online to read their customer testimonials. You will be able to get a feel for a company and determine their level of professionalism just by speaking to them on the phone or checking out their social media. Take the time to look over your options in your area and get quotes so that you can pick the right team to help you.
