Unblocked a gullley drain
"The man was extremely calm and cheerful and went out of his way, even in pouring rain to clear my drain. I had limited access as the neighbour had built an extension over the manhole, but it didn't phase him and he completed the job."
Cleaning two separate internal waste pipes
"Great service .. and initial call referred me into a senior site engineer who discussed the feasibility and then referred me back to admin for the quotation. Great admin and a super quick and efficient job on site "
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."

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."
Blocked kitchen gully
"Ben and Sean were excellent, cleared our blockage in no time, then checked further down the run and cleared a mass of roots from another manhole we had no idea had a problem. Punctual, polite and efficient. A job well done."
Clearing drains
"Great communication, timing, quality of work and friendly people. Thank you."
Unblocked a kitchen sink waste pipe
"The company was quick to respond to my initial call. The job was completed the following afternoon taking less than 15 minutes to complete. The technician was very polite and helpful. There was no call out fee or a dodgy plumber shaking his head for five minutes, making you think you've got a massive crisis on your hands. I will use this firm again in the future without doubt. "

Unlocking of sewage drains
"Turned up when stated, gave a courtesy call to let me know they would be here within half an hour. Completed work with no fuss. Came through the house to check back drain to ensure job done, took shoes off without being asked. Quick, professional, friendly and polite. Also a HUGE positive they charge a set fee for the job regardless of time completed rather than those that charge per half hour."
Blocked drains
"We recently noticed our downstairs WC was not flushing properly, and our outside man hole, was flooding and smelt terribly. I got in contact with happy drains and they hooked someone in within the next 2 days as I requested. The guy came to site, and told me exactly what he was doing and what he thought the issue may be. He fixed it in great time and was very informative. I hope I don't need to call happy drains again, but if we ever need someone to help us in the future, we will look no further. 10/10"
