Well, noseall:
1) I wouldn't know how to go about it
2) Its a 2-storey house and I have no head for heights.
Perhaps I should call in the pro's but then, I've seen all those programmes on the telly about cowboy builders and, knowing my luck, I'd get one of them. Also, thanks to being employed only part-time and now paying double income tax to Gordon, I can barely afford a professional repair job.
So, I rather hoped I might get a sympathetic response and some advice about the product I mentioned.
You call it a 'fast fix gimmick'. Can I assume then, that you are not a fan of this type of repair, even it it were temporary?
