Great Quality Seal – Perfect Fit!
I bought this uPVC window & door gasket seal (B001 Black) after first ordering the sample pack to ensure I got the correct size. I’m really glad I did because this seal turned out to be a perfect fit for my front door repair! The rubber is high quality, flexible, and creates a strong, airtight seal, effectively stopping draughts. It was easy to cut and install, and I immediately noticed an improvement in insulation. My door now closes snugly, and there’s no more cold air seeping through! If you need a reliable and durable replacement seal, I highly recommend this one. Great product and well worth the purchase!

Fast delivery, good quality seal
Like others, I found this a great quality seal to replace the old one around double glazed windows and doors, that had become hard and so was not making a good fraught proof seal. As with comments from others, the hardest part by far was prising the old seal out. Installing the new seal was a piece of cake. Great to have reasonably priced samples bag as well, to ensure you order the right profile. I originally ordered 10m to try on one set of windows, and have since ordered another 100m to do other windows and doors.

Good fit
Excellent. Order a sample selection first to get the right type, which I'd recommend doing. Type chosen fitted a dream, and makes a huge difference draft wise

Great product
The door seal was torn/ perished on the bottom part. It was easy to identify what we needed and was very easy to fit. Now we have a draught proof door.😃

Very Durable
Larger than the original but did the job after a struggle to install in existing channel but very sturdy for me to do so.

So easy to install
I first bought the sample packs which made life so much easier, value for money was excellent. When replacing the seal I totally agree with many other reviews, the most time consuming part of this is removing the old seal. Though I did find between an ice pick, flat blade screw driver and a pair of long nose pliers it wasn’t as bad as I was expecting. The new seal is installed within a couple of minutes. Very happy with the results.
