STORMGUARD 21SR3970020B UPVC Replacement Door and Window Rubber Seal - Black, 20 meters

Our conservatory is over 20 years old and the original door gasket seals had perished. They were brittle and hard, so sitting near the door in the winter meant you could feel a definite draught. Over the years I had tried to fix the problem with those stick on strips you can buy from DIY stores but they looked messy and were never man enough for the job. I had a glazing firm in who said that the original ones were no longer made - usual story - so I thought I take a chance and order online. I did some research and because they were in a state, I measured a bit of the old gasket as accurately as I could. This universal seal is perfect! So easy to fit, I was getting suspicious! The arrow head part just popped into the groove with a little bit of pressure, I got away without needed washing up liquid, but a great tip. As others have mentioned, there does seem to be a little bit of lubricant on already which definitely helped. I found that it pays to be a bit careful to keep checking that when you are pushing the seal in, to go back and check that where you first started hasn’t slid along, especially before you cut of the excess at the end. If it has moved, it’s easy just to push it back into place with a bit of thumb pressure.The worst part of the whole job was pulling and digging out the original seal from the grooves, especially at the base. I’m so pleased with the final result. As well as being more efficient, the door looks clean and brand new - better than it has for years. I don’t know why I didn’t do this ages ago.

I wanted to replace the seals around my uPCV front and back doors, and this did the job. It has a slight oil coating which is not only good for the rubber but also makes it easier to slid your finger along the rubber seal when pressing it into the door frame seal channel. Took about 10 mins for each door, and I'm a poor diy'er at the best of times!

Ordered yesterday, arrived today. Hardest bit was getting the old gasket out as it was so brittle. Used a very small flat head screwdriver in the groove to get all the old bits out then hoovered it, gave it a brush out with an old toothbrush and one more hoover to make sure there was no dust left. I didn't want to get it wet with any cleaning solutions to make it easier to fit the new gasket. The gasket comes neatly wound in a plastic tub with an airtight lid, pre-lubricated. I started at the top of the frame in the middle of the door and worked it all the way around back to the top without having to cut it once. It's flexible enough to go around the corners of the frame. I found that pushing the gasket into the groove and then wiggling my finger with pressure cross-ways against the direction of the gasket stopped me stretching it and ensured that the arrow-head shape on the gasket was tucked properly in on both sides. I turned the tub on the floor every so often to stop the gasket being twisted - this way I only needed to get out of the tub as much gasket as I needed to follow it around the frame. It was done in 10 minutes and looks like new now with a really good fit against the door. Very pleased with result.

Great product, easy to work with, couldn't be happier.Made my doors draft proof again. Highly recommend.

I can't help wishing that the original seals should have been in neoprene.Neither are these but they should last a few years.You need to mitre the corners. Using super glue, pull out the last few inches to join the corners.

Good quality and easy to install. Use a little soapy water to aid with install. With this I was able to replace the seals on one side of my Upvc door frame and also do 2 seals on a 4 x 4 meter window frame (6meters) and one seal on another 4 x 4 meter window frame (12 meters in total). Just enough left over for our small bathroom window (2 meters). Will happily buy another one for the rest.

Not bad, a little slack in the groove so feels like it will just fall out, however after a couple of weeks fitted in both a window and a French door it hasn't fallen out yet. Seals well enough but we did have a whistle through the door when it was very windy. A slight adjustment to the corner of the seal pretty much sorted that.

Purchased to replace a seal around conservatory door which had become brittle and started to flake away. Judged this to be the correct size or close comparison as the old one was compressed and is very similar. Tip - when removing the old seal it snapped or left bits in the crevice so I used a small allen key to hook bits out. Then when applying the new seal I used it again to help ease the edging into the door as it doesn't always simply push in. Worked well and snug fit when the door shuts. Can cut it with scissors or stanley knife. Only slight criticism is that as it comes in a round tub the rubber obviously curls which makes it awkward when fixing but don't see a solution to this from the sellers perspective. I ended up measuring sufficient length and pre cutting it which made it less curly. Would buy again should windows start to degrade.
