I'm not sure if there's actually anything that can be done, but when my dog was a pup she ripped off a section of wallpaper in my hall. Now I'm trying to sell my house, I was wondering if there was anyway to fix this (at least make it look alright) without repapering the whole hall. The bare bit of wall is over a corner, and if about 30cm squared, if it makes any difference! Any ideas??
I had bits of wallpaper ripped off in my bathroom. I did not want to strip wallpaper off and a decorator told me to use polyfilla (not ready mixed, not pliable enough) over the area of the missing paper. Sand off when dry and then paint. Worked for me. You only notice it when it is pointed out. Hope this helps.
If people are genuinely interested in the house, then I don't think it will bother them to be honest - chances are, most people redecorate as soon as they get a chance anyway.
