This is our wall between us and next door. The builder who is installing a new boiler drilled right through and knocked some of out plaster off! He’s offered to come round and patch it up, but if he does things like this I don’t want him in here! Might take a note of his phone number. I don’t want him causing a problem. I’m in two minds whether to put in a complaint to trading standards. I’m more concerned that he does the work properly for our neighbour who is very elderly.
