If your window is not properly sealed, you can be wasting energy on your HVAC usage. Improperly sealed windows can make your AC work overtime to cool your home in the summer. This article will explore how to check if your windows are improperly sealed and how they can be fixed.

Why Window Seals are Important

Most modern windows are double or even triple-layered to help keep your home insulated. This is done for energy efficiency. When windows are made, the air between the layers is vacuumed out and replaced with an inert gas. Inert gases, such as argon, can help insulate your home. Noble gases transfer heat less effectively than even vacuumed space. However, when the seal breaks, it also means that the efficiency becomes much worse.

How to Know if Your Window Seal Has Failed

When the inert gas escapes, air and moisture from the surrounding area can enter the window. A common sign of a broken seal is fogginess or signs of moisture within panes of glass. Another sign would be a higher-than-usual energy bill. You may also notice damage around the window’s caulking.

Can You Repair Or Replace A Broken Window Seal?

If your window damage is just around the caulking, that can be an easy fix. A window repair specialist can help you determine if the inner seal has been breached. Otherwise, you should check to see if your panes are still under warranty from installation. If it is, you may be able to get partial or complete replacement coverage. If the seal is broken and the window is not under warranty, you have 2 main options. Replace the window, or defog and seal.

Defogging And Sealing Services

A window that is fogging and experiencing condensation as a result of a broken seal can be repaired with a defogging service. This is generally less expensive than a full replacement. However, it will not be as energy efficient as a new window. First, a window specialist will create a tiny hole in the window. Then, they expel all of the moisture within. From there, they treat it with an anti-fogging solution. Then, they seal up the panes. The hole they drilled is also sealed. This treatment is done without replacing the panes and can be done very quickly.
Defogging can be a good idea if you only have 1 or 2 windows with this issue. If more of your windows are losing their seal, you should consider replacing them.

Replacing Windows

Replacing windows with newer, sealed models can be a good way to insulate your home and ensure that it is more energy efficient. Depending on the manufacturer and specs, you may not need to replace the window frame as part of the re-installation. For longer-lasting windows, look for products that feature extended warranties. Many companies will offer 10-20-year options, but some may offer lifetime warranties.

Hire a Professional

Window repairs should be done by a licensed professional only. DIY repairs can lead to improper seals, poor closures, and more. DIY defogger kits can have mixed reviews and mixed results. For window replacements, professional installations can help reduce potential issues and avoid voiding warranties.
