Back garden drain unblocked
"The challenge was to unblock my drain in the back garden with no rear access. All equipment needed to be brought through the house. It was too much of a risk to use a pressure washer for a single crew. However the engineer fully cleared the drain using his available tools/ equipment."
Outside drain clearing
"Calm her within an hour of my call. Polite and efficient from start to finish. Really happy. Thank you."
Happy Drains = Happy Homeowner
"Fantastic service, drain was unblocked in no time. Mark was fantastic and professional. Thank you, price was great with no hidden cost. I had a builder who advised they may have to lift the tiles to get to the drain, luckily escaped that as I would have had to replace the entire kitchen "
5* Service was Over and Above expectation.
"This is the second time I have used Happy Drains the Service provided last time was superb. This time it was even better! With no appointments available to clear my elderly mothers blocked toilet, Happy Drains rearranged a schedule to conduct the work to limit inconvenience. Joe attended and was absolutely first class keeping me updated directly at the request of my confused elderly mother. It is so reassuring to be kept informed of the detail when you are 80 miles away so I could explain it in simple terms to my mother, I recommend Happy Drains 100% and commend Joe for the 5* Service."
