Does Redrow who built the coach house have to put this problem right. it as cost me £137.00 so far for Dyno rod and should they legally reply to me in response to my email with Dyno report and photo.
my coach house is a leasehold flat which sits on top of three garages, one garage is mine. the waste pipe may go underneath one of the other two garages which is not mine. could I still get the job [blockage] done with their permission?
