Review: Easy to use great product - Great product and an easy fit just make sure you measure
Review: Good product, easy enough to fit it yourself but do measure first - Having noticed a draft coming from the window, I found online that the seal might be the problem and looked at how to replace it (there are some good videos to show you how, just do a search). I actually removed the window and brought it inside, which made it easy to remove the old seal and put in the new one. It would’ve been very fiddly to do it around the hinges otherwise. I would consider myself to be a competent amateur DIY’er, and I managed fine to both remove the window and to put in this new seal. I did measure the gaps as recommended by other reviews, to make sure I had the correct seal, and it popped in just fine. Just take your time to go round and press it in, sometimes needs an extra press after so a second check round the edges is worth it. So far no draft, so I think it’s a job well done. Very pleased with it.
