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! "

Good communication and job done same day

"Excellent, speedy service from a friendly, knowledgeable drainage engineer. Happy Drains will be my choice next time."
Kitchen Waste Clearance
"Very effective service, timely arrival (when promised), collaborative approach (listened to what work had already been understaken), speedy resolution (less than 20 minutes) - would definitly use again"
Great service
"We had a very problematic drain blockage that only had access from the toilet and no manholes. The guys turned up, very professional, polite and persevered with the issue until the drains were cleared. I would 100% recommend to anyone who requires this type of service. "
Outside runoff drain to mains was backed up and overflowing.
"Called them on a Saturday when the drain was especially playing up and within 20 minutes they rang back with the job booked in for the Monday. Friendly, prompt service on the phone, same again when the fella turned up. Done in 10 minutes. Didn't have to pay him then and there, but instead was issued online invoice and link to super-simple payment procedure. Brilliant. Highly recommended; will definitely use them again - just hope I won't have to! "
Clearing a blocked outdoor kitchen drain
"The Happy Drains service was fantastic. Within half an hour of my calling, they had arrived and the chap was very helpful and polite. Nothing was too much trouble, and everything was taken care of in 20 minutes though it was a tough job. Good price with no hidden extras and completely fair - I can't recommend them highly enough! "
Blocked drain from ensuite.
"Called Happy Drains about 9am as my ensuite toilet was blocked which was the only working toilet at the time. They advised that someone could be with me between 10am and 12noon. Two guys arrived just after 12 and went to work straight away to clear the blockage, which they did quickly, cleanly and professionally. Based on this I would use Happy Drains again. "
Jetting blocked drain and clean up of surrounding area
"They were professional on the phone and throughout the process. The Engineer was polite, timely, explained what he'd do and said he'd clean up the area afterwards. Job was done perfectly and their price was considerably better than others and as such represented excellent value! Hope I won't need them again (?...) but should I do, they would be my automatic choice. Heartily and unreservedly recommend them based on our experience "

Unblock toilet
"Unplugging the toilet went really quickly, such a nice informative man."
Foul drain needed unblocking
"Happy drains kept in touch from the 1st contact until the job was done.Very reliable job done very well, quickly and very tidy.Got in touch before payment was made as job was for my elderly mother.Definitely recommend "
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"
