Hi I live in a ground floor flat in a two story building us and one flat above. Last year a guy came to do guttering and noticed a crack in pebble dash between upstairs kitchen window and where the gas pipe entry is. The crack hasn't got any bigger in this time and 8s only noticeable if you know it's there is is about 1 to 2 mm even all the way(doesn't actually go as low as our flat ). I also have a crack under my window that is slightly thinner and again hasn't moved.....looking to sell next yr am in Scotland so have to get home report and having seen the detail they go in to I am worried that they will fail us and we won't be able to sell. We live by a railway and the embankment is about 7 meters away from the wall with trees but not humongous ones sorry to go on but quite anxious! Any opinions would be fab thanks
