What’s the point of changing the rubber seal on my UPVC windows?
A rubber seal window replacement may be necessary if you experience draughts or see condensation accumulating on your windows. If you need information on replacing the seals in your uPVC windows, you can find it all in this post.
The seal around your windows may stop working because of normal wear and tear.
If your seals aren’t doing their job properly, warm air from within your home can escape, and cold air from outside can enter, leading to greater heating costs and less comfort.
You should think about resealing your windows if you want to reduce your heating costs and eliminate draughts.

Step 1: Remove old rubber
Take off the old rubber seal first. This should be easy to pull off with your hand.

Simply push the new rubber seal into the holes to put it in place.
Step 4: Repeat for all sides
Do the step above on all four sides of the window until all four sides are fixed.
Step 5: Seal the gaps
Put a little silicone sealant in the corners if you see a gap. This will close it up fully.
