Why Replace Your Window or Door Gasket?

Over time, existing rubber seals can become compressed, hard, brittle or shrink, reducing their ability to maintain an effective seal.

Replacing a worn gasket can help restore the seal around your window or door, reducing cold draughts and helping prevent rainwater from entering around the opening sash.

Easy Push-Fit Installation

Installation is quick and straightforward. Remove the existing gasket, clean the gasket channel and carefully push the new seal into the existing groove around the window or door frame.

For the best result, avoid unnecessarily stretching the rubber during installation.

Choosing the Correct Gasket

Please compare the profile and dimensions carefully before ordering. uPVC windows and doors use many different gasket profiles, and similar-looking seals may have different fitting dimensions.

For the most accurate match, we recommend purchasing our sample pack before ordering a larger quantity.

The sample pack contains approximately 100mm of each available gasket profile, individually labelled with its corresponding code. This allows you to test the profiles directly in your window or door and identify the best-fitting replacement.

Important

Please check your existing gasket against the profile shape and measurements shown in the listing images. Compatibility depends on the gasket channel/profile used in your particular window or door system.
