Hi I live in a terraced property and next door are having a large 2 bedroom extension done and I honestly can't see out my windows, the door in filthy, my plants are covered in dust and the car is filthy from concrete dust. Should the builders pay for my windows, door, and car to be cleaned once they have completed the extension. Being a terraced house they have used our roof for scaffolding even drilling it into our wall (without asking!) and always use are parking spaces which we have put up with. The neighbor's have moved out whilst it is being done (lucky couple!) . It has been 3 months of dust and filth to-date and not finished. Any answers please - is it something builers must do after the build or not ?
