What's in the pack?

Stormguard Universal UPVC Replacement Seal in your chosen length


Please refer to size chart.


  • Carefully cut out a small 15mm section of old/damaged seal and push fit a similar length of the new seal to ensure you are happy with the new fit. The shape may vary but this should not adversely affect performance.
  • Please note that the arrowhead is offset from the centre so you can fit it either way to provide the best seal.
  • Remove the old seal by pulling or cutting it, make sure the groove is left as clean as possible; insert the arrowhead of the new seal.
  • The new seal is pre-lubricated but if additional lubricant is required we recommend using a small amount of washing up liquid.
  • Should the arrowhead be too loose in the groove then a small amount of silicone can be used to secure it into place.
  • On some windows and doors a warping of the frame and closing leaf occurs; this means there is sometimes a larger gap to one corner.
  • In such cases, as well as renewing the old seal in the groove, it may be worth fitting Stormguard Self-Adhesive Extra Thick Memory Seal (tolerance 3mm-8mm) onto the offending corner of the door or window leaf to ensure there is a good seal at the point of distortion too.
