At the front of our property the drive way is almost at the same level of the damp proof course, this needs rectifying. Round the corner, on the side of the property (probably 1.5m away) we have a down pipe which goes into an old metal downpipe which in turn goes into the concrete. This is all backing up, we think because a bit up of dirt has happened at the bottom.
All of this needs fixing but what trade would do it?
