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.

Good quality
Bought to rejuvenate my upvc doors, fantastic bit of kit, easy to use and fit, definitely will buy again when needed and cheaper than a new door!

Great product
The seal was easy to replace and made a difference for draft exclusion! If your seals have been in a while and having been treated with a lubricant spray they have probably been crushed and gone hard and the only way to get them back it to replace! Really do recommend!

Much needed seal for my windows
Needed to replace the seals on my uPVC windows and doors as the rubber had gone hard and perished. I purchased a similar item from a well-known DIY outlet but needed extra. Although the dimensions are ever so slightly different in this tub, it is cheaper and 5 metres longer but fitted fine. The job is fiddly. I found that pulling at a corner and pushing the sealant in the same direction, I could usually coax the whole lot out. Fitting is more of an effort particularly upstairs windows. You have to use your thumbs to press into the track, I did use a plastic push tool to help but the best way was to remove the window and install the seal on the floor. Needs two people to do this. I have also replaced the seal that sits on the frame on a few windows as well. It fits, works (the windows have a slight resistance on final closure) and I'm sure will last for a number of years.

Sore thumbs! - but I am not an expert!
found it hard to fit in my "old doors -15 years of age) have sore thumbs and fingers!. However seems to be working although quality compared to "old" seal looks lower. price ok and some tips on fitting available online. however beware the expert fitters they make it look so easy lol!

Resealed an old window
Great product. We stripped old broken down draughty seals from a double glazed window and replaced with Stormguard. It's great. Window is no longer draughty, it's quiet when closed and sealed perfectly. Once we got the hang of installing, it was OK. Really pleased with the results for not much money, like a new window now! Will definitely buy again if we develop any problems with other windows

Bonjour, j'ai reçu ce joint et la partie qui rentre dans la fenêtre n'est pas centrée. Est-ce qu'il y a un sens ? (voir photo)

Produit de qualité et facile à poser. Mais si la couleur blanche n’est pas une obligation vous pouvez trouver le même profil en noir et moins cher…

Extrêmement déçu car, en plus, le joint est de qualité. L'épaisseur n'est pas celle annoncé. Le joint est marqué à plusieurs endroit dans la boîte ce qui nuit à l'étanchéité finale. Prenez de la marge !
