Main soil pipe blokage was cleared.
"Professional, courteous and reliable. The call was booked with a friendly and professional demeanour. The tradesman who visited was clear in explaining what was required and the work that was carried out after he'd completed it. The blockage was mainly due to a build up of limescale over a very long period of time and was cleared quickly and effectively. Wouldn't hesitate to recommend Happy Drains."
Drain clearance
"I called Happy Drains to attend to an overflowing drain manhole in our front drive. Their response on the telephone was prompt, courteous and helpful. Their engineer arrived slightly earlier than arranged, after telephoning to confirm that this would be acceptable. He fixed the problem in less than 30 minutes, and checked that everything was satisfactory before leaving. "
Inspection and Jetting of all drains;
"Martyn Roberts, the engineer, is a star! Courteous, neat, tidy, and efficient - he went above and beyond to clear the silt built up from Storm Babet, Storm Henk - was cleared out of all drains into my property - professional, experienced, efficient and so courteous. First in class. Thank you!"
Unblocking drain
"Having used Happy Drains previously, I contacted them about a blocked drain on my property. They responded immediately, sent engineers who were prompt, professional and friendly and had the job done in 25 minutes. Just to top it off, the price was the same as my last call-out with them two years ago. Excellent service all round."
