Make sure that the strips are firmly placed on both sides of the channels in order to create an airtight sealing when the sashes close. For casement windows which are mounted on a hinge and need to be opened using a crank, you can use foam tape to secure the sides, top and bottom of the window stops.

Foam tape is inexpensive at less than a buck per foot, and easy to set up. It is suitable for gaps up to one inch. If you need an extra durable, stronger sealer for gaps that are larger than an inch, consider all-wool felt or EDPM (ethylene propylene diene monomer) rubber. Those types are suitable for the bottom of the window and door seal repairs sash as well as doors that are open and close frequently.

Replacing the window seal can be a complex process that requires expertise and equipment from a professional. It is best to employ an expert for this task because it's not something that a DIYer can tackle. In addition, certain windows need to be dismantled in order to be replaced, and this is not an easy task for someone who is clumsy or careless.

Sealant

Modern double glazed windows seal replacement or triple-pane windows have an inner seal (or seals) between their panes that helps to keep argon and Krypton gas inside the window for enhanced insulating properties.

There are many types of silicone sealants available to pick from, but be certain to select one that has moisture resistance and high adhesion. Some silicone sealants are designed for use with uPVC, and they have good flexibility. Others are a little more durable and are designed for exterior use. Some are even infused with anti-fungal substances that prevent the growth and spread of mold and mildew.

Changes in humidity and temperature can cause window seals to fail. This could cause them to expand and contract, which can eventually cause the seal to break.

A window seal that is damaged can be caused by improper installation or maintenance of the window, especially in the event that there is gaps between the glass and the frame. This can allow water to enter the frame or sash and cause damage, or allow dust to build up between the panes.
