do windows with broken seals need to be replaced

Do windows with broken seals need to be replaced? When a seal breaks, it’s one of the top signs that window replacement is around the corner. But why is a broken window seal such a big problem?

Let’s talk about why window seals are a big deal for window performance, and if total window replacement is always the best option.

What is a broken window seal?

What’s the deal with window seals? Modern windows often contain two or three panes of glass. Inside those panes is a sealed space in between filled with invisble gases like argon or krypton. These gases enhance the window’s insulation, which keeps you warm in the winter and cool in the summer.

When the seal around this space breaks, it compromises the window’s performance. The broken seal allows for the energy efficient gases to escape, which is one of the major reasons why you’ll need to replace the window.

What’s so bad about broken window seals?

A broken seal allows argon and krypton gases to escape right through the glass. These gases are important for maintaining insulation in the window. Without them, the window can’t maintain a consistent temperature within your home–meaning your home won’t feel oh-so-toasty like it should.

What’s worse is that broken seals cause a considerable amount of energy loss. In fact, up to 30% of your home’s heat is lost through inefficient windows. Yikes!

Looking for other reasons why broken window seals are a bad deal? Windows with broken seals will fail in the following areas.

Insulation failure

The main role of a window, apart from letting light in, is to insulate your home from the elements. Argon and krypton gases are insulators to keep your home warm in the winter. When the gases escape, this leads to insulation failure.

Increased heat transfer

When a window seal breaks, heat escapes through the glass panes. This is the process of failing insulation while the window no longer keeps your home comfortable.

Not meeting Energy Star requirements

Energy Star is a program that sets energy efficiency standards. A window with a broken seal fails to meet these requirements since the energy efficient gasses are no longer present. These gases are a component of Energy Star’s efficiency requirements, which you can read more about by clicking here.

Spotting the signs of a broken window seal

foggy windows

Do you have foggy windows? This is the most common sign of a broken window seal. Keep in mind that there is a difference between foggy windows from condensation and foggy windows from a broken seal.

But how do you tell the difference? Foggy windows from a broken seal won’t ever wipe clean, no matter how much you try. 

If the fog is coming from condensation, you can wipe it away with your hand.

Other signs of window performance problems:

Ice or Frost Buildup

Here in New England, you might notice ice and frost buildup on the window’s glass. This is a sign that moisture is getting inside and freezing. You may especially notice this if your windows are leaking water.

Feeling Drafts

If you feel air coming through the window, you’ll need to think about new window installation. Drafts most commonly come from the sash, the sill, and where the sash meets the sill.

Rising Energy Bills

A subtle but significant sign of broken seals is an increase in your energy bills. This shows that your heating or cooling system is working overtime due to poor insulation.

Do windows with broken seals need to be replaced? Why replacement is the best choice

Replacing a window with a broken seal allows you to address any other existing issues with the window, such as frame damage or outdated style. Some of these fixes can include:

Improving your outdoor views with clear glass

Replacement makes your window glass clear again, eliminating unsightly fogginess.

Enhancing energy efficiency

New windows, especially those meeting current Energy Star requirements, can significantly improve your home’s energy efficiency. This leads to lower bills and a more comfortable living environment.

Easy to use and maintain

While not related to performance, new vinyl windows are very easy to maintain. They won’t require sanding, staining, or painting. They also easily open and close, allowing you to enjoy your windows for many years to come.
