Frequently Asked Questions:

How can I check if this seal will fit my windows?
Pull a small piece of your existing seal away from the frame and compare it to the size diagram shown in the product images. This seal fits grooves between 3.2mm and 4mm wide and seals gaps of 3-5mm. Measure your door or window gap before buying. If your gap is larger or smaller, please check our other listings for alternative solutions.

Do I need any special tools for installation?
No special tools are required. You may find a flat-bladed screwdriver useful for removing the old seal, and scissors for cutting the new seal to length. The installation is a simple push-fit process.

Will this seal work if my window frame is slightly warped?
Yes, in most cases. For areas with larger gaps due to frame warping, you may want to consider using Stormguard Self-Adhesive Extra Thick Memory Seal (sold separately) on the affected corner in addition to this replacement gasket.

Can I use this for both windows and doors?
Yes, this replacement gasket is suitable for both uPVC windows and doors that have the correct groove size and gap measurements, making it a versatile solution for compatible fixtures throughout your property.

What if I'm having trouble with installation?
If you're experiencing difficulties, ensure the groove is completely clean before installation. The arrowhead is offset from centre, so try inserting it the opposite way if it feels loose. For stubborn sections, apply a small amount of washing-up liquid as lubricant. If the seal remains too loose in the groove, a small amount of silicone sealant can secure it in place.
