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"

Partially blocked soil pipe.

"Glad I called Happy Drains when I got an issue with my downstairs toilet overflowing! Damian attended within 24 hours and got straight to it, no fuss, no "hmmmm... (you know what comes next) deep breath intake, etc..). Damian was a pro and worked his way round the problem until it got done. I'm not squeamish for these kind of jobs but I soon realised that blocked drains require professional equipment and experience! Happy customer"

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! "
