A few very Happy Customers...

kitchen drain completely blocked
"Their service was exceptional. Very professional, and they solved the most important problem! Considering that two plumbers and Thames Water visited us but only tried to rush and squeeze extra money, resolving the problem partially. "
Drain and sewer clearance
"Realised I had a problem when had to almost swim to the car. Thought I was covered by B Gas Homecare but I wasn't. Called out Happy Drains, competitive price, friendly and helpful on the phone. Turned up when they said they would. Quickly assessed the situation and cleared the sewer. Cleaned up and left. Staff were friendly and polite. I couldn't ask for more, would recommend them "
Clearing a blocked manhole
"Tommy was excellent. Rang and got a same day appointment. Phoned ahead to confirm arrival time. Unlocked the drain quickly with a rod but followed up by jetting the drain to make sure it was entirely clear. Provided a number of good tips on how to avoid future blockage. Tommy was polite friendly and very efficient."
Kitchen sink drain cleared
"The engineer from Happy Drains cleared my slow running kitchen sink drain in minutes. The plumbing is not straightforward but he saw the issue and cleared the blockage very quickly without wasting time. He was very thorough and cleaned up afterwards. My sink now drains faster than it has in years and I am very happy. I was told exactly how much it would cost beforehand, so no hidden extras, plus the engineer offered a 28 day call back for free if the issue wasn't resolved. "
