So I was looking at getting some storm guard upvc gasket to replace the old one. Over time it looks like it has compressed but not sure. The reason I'm not sure is because I can see a gap in the gasket when the door is closed. So my question is if it's compressed surely there would be no gap? And secondly would you get a thicker one than the one in there already to bridge the gap or should you always get the same spec as the one your removing?
Also one final thing. - the lower kitchen units in my house let in freezing cold air when you open them... Of course the one under the sink has the drain pipe leaving the house but why are the all freezing behind?... You can feel the cold breeze when you open them. You can just about see under the skirting around the kitchen and it seems like the previous owner has installed them to cover exposing brick.... Wild.... Really hope you can help me in both scenarios Thankyou
