Blocked drain
"We had a drain which had got progressively blocked over a week, with a complete blockage over the weekend. Found Happy Drains via a Google search and on the Sunday morning, requested a booking for the Monday via their online form. Monday am I get a call from their office to book the job in, 30mins later they arrive and have the problem sorted and advise me how best to avoid the same problem in the future. Very good service, would recommend. "
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."
Drain Jetting
"Happy Drains were incredible, I requested a quote and received one in mere minutes through their website! I tried a few competitors and a few came back a day or two later and others I still haven't heard from! I found the quote given to be competitive and they had good availability which worked around my busy lifestyle. I highly recommend Happy Drains and will continue to use them for any other difficult drainage or plumbing issues!"
