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.”
Drains and stack pipe unblocking
“Really good experience. Very polite and professional. Slightly odd reason for a blocked drain (surprisingly tiling cement was blocking the base of the stack pipe), but the Happy Drains colleague came and cleared the blockage for me. They did a great job. Easy to deal with and made the process really smooth. Good pricing too. I’d happily recommend them and use them again”
Unblocking drain.
“The man arrived within about 30 minutes, unblocked my drain quickly and efficiently. Very pleasant and polite.”
Unblocking a kitchen runaway.
“They arrived within the stated timeframe, the man explained the problem and how he would deal with it. The work was done swiftly and satisfactorily. Wouldn’t hesitate to call them again if necessary or to recommend them to anyone else.”
