Highly recommend
"I used Happy drains to survey the drains of the house I bought in Kew Gardens SW London. From the initial phone call they were professional and efficient and friendly. The guy turned up on time, very professional and knew his stuff. Turnaround of the report was super quick, it was comprehensive, and included video and was easy to share with the estate agent . It gave me peace of mind to continue with the purchase. They were competitively priced and I would highly recommend "
Jet washing rainwater drain
"The job was done quickly and thoroughly by Derick who was polite and considerate throughout."
Excellent Service
"I had a blocked exterior drain that was backing up into the house and needed an emergency call out. I called for a quote and Happy Drains called me back to say they couldn't get out to me due to unforeseen circumstances but were Happy to talk me through clearing the blockage over the phone. 10/10 service!"
Resolved blocked toilet
"We reached out in the late morning and the issue was resolved by 3:30pm the same day. Very quick and efficient service, the engineer was very polite and friendly. Will definitely use again if further issues arise."
