Blocked toilet - resolved promptly and effectively

"Great service from Luke who managed to get our upstairs toilet unblocked in less than half an hour. Good customer service, was able to arrange a convenient time for the visit and Luke was very polite and courteous. The price was much cheaper than elsewhere, I will definitely use Happy Drains again for any future drain blockages!"

Overflowing Sewage

"We emailed at 6:30am and Happy Drains were on site at 10am and the problem was fixed in just under an hour."

INitially cleared blockage but found root mass in the sewer so cleared that as well

"Not used this company before but when I was unable to clear a blockage in my sewer line I gave them a call. They were responsive and the engineer just got to work, identified where the sewer ran then blasted it clear. The sewer was running again within 15 mins. The knowledgeable engineer said he believed there were roots in the sewer as he could "feel" them. A camera run showed the root mass and where located. He blasted the roots from the inside then found that the majority were ingressing through the side of the sump on one of the manholes so cleared those too. Highly recommend this company"
