Very polite on the telephone and also the drain engineers on site were very polite and just got on with the job.

We received a call 45 mins before arrival and the drains which had been blocked for 48 hours were unblocked within a few minutes, which was excellent as man hole covers in a neighbours garden were opened and showed that the drains were being exclusively used by our house. Excellent job by Happy Drains. Wouldn't hesitate to use them again. Quick polite and courteous."

"This is the second time I have used Happy Drains the Service provided last time was superb. This time it was even better!

Joe attended and was absolutely first class keeping me updated directly at the request of my confused elderly mother. It is so reassuring to be kept informed of the detail when you are 80 miles away so I could explain it in simple terms to my mother, I recommend Happy Drains 100% and commend Joe for the 5* Service."
