Well I looked up on Google how to fill the cracks under the window frames in the house and I know that I can do it myself. But I went on the village bus to Pomorie yesterday and they only had silicon which I didn't want. Today I went to my village DIY store where they sold me what looked like a large sliver foil covered sausage. I pieced it but the stuff that came out was clear, thick and sticky I've tried to use it but it looks as if I've covered the crack with clear sticky tape. So I'm thinking that on Monday I'll get the other village bus and go to Prakticar near to the Mall and see if they stock Pollyfilla. What do you think?
