Kitchen sink drain cleared
"The engineer from Happy Drains cleared my slow running kitchen sink drain in minutes. The plumbing is not straightforward but he saw the issue and cleared the blockage very quickly without wasting time. He was very thorough and cleaned up afterwards. My sink now drains faster than it has in years and I am very happy. I was told exactly how much it would cost beforehand, so no hidden extras, plus the engineer offered a 28 day call back for free if the issue wasn't resolved. "

"Very courteous plumber, explained everything he was doing and investigated thoroughly to find out the problem and then fixed it."

Welwyn and Hertfordshire drain services from a firm receiving great feedback...

Blocked Soil Pipe
"This is a great Company. I called them at 10.30am to request a visit to sort out a blocked toilet system at my daughters place and the Engineer arrived at 3.00pm (within the time slot initially given). Within minutes he (Luke) had identified the issue and not long after, the blockage was cleared and a working toilet was restored. I would recommend these guys to anyone seeking a prompt service, provided by people who know exactly what they're doing."
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."
Clearing blocked drains
"I called the company after a recommendation and a man arrived later the same day. He was friendly and professional, quickly set up the equipment and worked his magic with the two blocked drains. He offered advice on keeping the drains clear in future and made sure the area was clean and tidy before he left. I have no hesitation in recommending this firm."
