Replacing Seal on Windows

Window seals are designed to last, but they will eventually wear out. A damaged seal can affect the windows performance, visibility and energy efficiency.

Make sure that the strips are securely seated on both sides of the channels to provide an airtight seal when the sashes close. For casement windows that are on a hinge and have to be opened by a crank, you can use foam tape to seal the top, bottom and sides of the window stops.

Foam tape costs less than $1 per foot and is easy to install. It's suitable for gaps up to an inch wide. If you're looking for a durable, stronger sealer for gaps that are more than an inch wide consider EDPM (ethylenepropylenediene monomer) or all-wool felt.

Condensate forming between glass panes is a further indication that the seal on your window has worn away. This signifies that the gas in the glass panes is depressurized and is now composed of water vapour and air instead of argon and krypton, which are denser than air and have better insulation properties.

Replacing the window seal could be a difficult task and requires expert knowledge and equipment. In the majority of instances, it's best hiring a professional do this job for you, since it's not something that could be done by a typical DIYer. Some windows will need to be dismantled to be replaced. This is not a job for the clumsy.

Sealant

Modern triple-pane or double-pane windows feature an inner seal (or seals) between their panes. These seals aid in keeping argon or krypton gas in the window to provide better insulation properties.

There are a few different kinds of silicone sealants to pick from, but be certain to select one that has high adhesion and moisture resistance. Some silicone sealants are designed to work with uPVC and are flexible enough. Others are a bit more durable and are made for outdoor use. Some have anti-fungal ingredients to prevent the growth of mold and mildew.

Temperature and humidity fluctuations can cause window seals to fail. The seals can expand and contract as a result.

A poor installation or maintenance may lead to a broken window seal, especially when there is an air gap between the glass pane and the frame. This can cause water to leak into the frame or sash and cause damage or allow dust to accumulate between the panes.

A broken window seal may cause fog and condensation. This can be caused by a loss of inert gas or depressurization. Professional defogging solutions can be employed to solve the problem, but it is not optimal. The defogging process can only eliminate the moisture that causes fog, and will not replace the argon gas initially used to boost the insulating value of the window.

In some cases the issue is caused by extreme temperature changes. This can cause the glass to expand and contract, which could put pressure on the window seal. A window seal that leaks can also be caused by harsh weather conditions, such as high humidity.
