Why Replace Your Window Gasket?

Over time, existing window and door rubber seals can become hard, compressed, brittle or shrunken. Once this happens, the gasket may no longer create an effective seal around the glazing unit, potentially allowing unwanted draughts or moisture through.

Replacing the worn gasket with the correct size and profile can restore a secure seal and help improve the weather resistance of your windows and doors.

How to Choose the Correct Gasket

Gasket profiles and sizes vary between different uPVC window and door systems. We strongly recommend checking the shape and dimensions of your existing gasket before ordering.

For the most accurate match, consider purchasing our gasket sample pack first. The sample pack contains approximately 100mm of each available gasket profile, with each sample individually labelled with its corresponding product code.

You can test the samples directly in your window or door to identify the profile that provides the best fit before ordering the required length.

Important: Please ensure you select the correct gasket profile for your window or door system before ordering.
