I bought an ex-council house about a year ago.
I've just realised that all the double-glazed windows, and even the front door, now have a space/crack between it and the surrounding structure.
Each of these windows/doors are now letting drafts through.
Either I didn't notice it when I first moved in, or the paint around the edges of the doors/windows was hiding the cracks and has finally decomposed, or the doors/windows have shrunk(!?).
As I'm getting a draft through these holes, I assume these holes extend to the outside of the house.
Is this kind of thing normal?
Do I try and paint over it? Or should I use a sealant on the inside of the house? Or maybe tackle the problem from the outside of the house?
By the way - I'm a rubbish painter.
Any suggestions you could offer would be very welcome!
