Good service and fixed the problem.
Happy Drains did a great job, it was easy to book an appointment with them over the phone, their engineer got in touch direct he arrived on time and had the blocked drain fixed with no fuss.

Washing machine back flow caused by blocked drains
I am really grateful that the problem has been solved because of the excellent services provided by Happy Drains. The engineer came to my flat and tried their very best and efforts to find out what was going on and to solve the problem. Before that, I tried to contact two plumbers but the first plumber said he could not solve the problem and the second one was a "no-show" because there was no parking space in my building. The engineers of Happy Drains are really reliable. Highly recommend Happy Drains to everyone who encounters similar problems!

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."
Foul smell in bathroom
"I had a disgusting smell of sewage coming through my pipes in the bathroom, after trying to solve the problem myself unsuccessfully i called Happy Drains and Alex arrived as planned, as soon as he flushed the loo he knew instantly what the problem was - a blockage in the pipes. To say he solved my problem is an understatement, he went to both of my neighbours to check their drains until he found the blockage and then went ahead and flushed the pipes through. He was a true gentleman, polite, funny and very caring. I highly recommend this company and especially Alex. Thank you Alex"
1st time customer - Excellent experience
"1st time using Checkatrade. Polite and efficient experience from beginning to end, with clear/ transparent pricing + quick availability of plumber. I chose to use Happy Drains... who were available same day to unblock kitchen sink. Damian from Happy Drains was friendly and cheerful, but always polite and professional and persistent with unblocking drain. Damian had a powerful acqua vac that was required to unblock the drain. Not an easy job, but Damian persisted and determined to get job done. No surprises with charges...exactly as quoted and very reasonable. Recommended."
Quickest and easiest unblocking i've seen!
"After so many expensive quotes from other companies regarding a clogged drain outside our kitchen window - Happy Drains answered our questions on Checkatrade and gave us a set quote - After talking to them on the phone, the team were kind, honest and fully transparent about how the day would go - One of their team members (unfortunately didn't get his name) came over, took one look at the drain, unblocked it and was on his merry way! Will definitely be recommending this company to friends and family!! Thank you so much team! "

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."
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. "
