Drain cleaning
"Very professional, did a great job made sure water was flowing properly . Happy with this company."
Unblock an outside pipe
"Unfortunately the pipe was blocked with concrete which appears to have happened when the garden fence was erected. However, the tradesman wrote the reason it was blocked on the invoice which helped when I contacted the tradesmen who erected the fence."
Clogged kitchen sink pipe
"I was really glad with the service that they provided. They just sent someone the same day that I called ,and they were able to unclog the pipe within the same day. I was really happy, I wished that I would've called them sooner as I was trying for over a week to clear it myself without getting any results... and I also was really happy with the customer service and their payment method, It was really easy to pay with the link that they sent me and they charged me the amount that It was agreed by phone, without any extra fees... I definitely recommend it to everybody "

They sent someone out who arrived at 11am - he unblocked the sink, checked the shower and toilet in the same bathroom, took photographs and cleaned everything perfectly. Such great service in such a timely manner. We also use Happy Drains at my work place and have always found their team great!"

UNBLOCK OUTSIDE DRAINS
"This company has provided excellent first class service. DYNO ROD previously accepted our request to clear but on New Year's Eve morning declined as they were too busy and couldn't reach us until after New Year. Found HAPPY DRAINS on line, phoned and the contact was excellent, arranged a visit within an hour. Engineer arrived well within this time span was brilliant, cleared the problem quickly and efficiently. Based upon this work we would HIGHLY RECOMMEND HAPPY DRAINS and have logged their number in our Contacts folder for any future problems, THANK YOU."
