Great communication and fixed price drain clearance
"From the first phone call enquiring about drain clearance with Emily to the actual work being carried out was less than 3 hours. I knew immediately upfront what the cost would be and how much extra if a Saturday call out was needed. I was kept informed by phone and email and received a call from the engineers 30 mins prior to arrival. They very quickly identified and cleared the problem clearing up any slight mess they made. Hope not to need this service again but if I do would Happily use Happy drains again."

Blocked drain that runs under house.
"Had a blockage from the sink drain that runs under my house. Called at 9:05 and engineer arrived within 3 hours and got the problem sorted within 25 mins of arrival making myself and my drain happy. Had the same done 3 years ago and cost nearly double with one of the larger companies so decided to go local and worked out well on all fronts. "
