Drain unblocked

"Prompt, professional, courteous and knowledgeable. Sewer drain unblocked quickly and the chap gave me some advice in order to prevent future problems."

Clear kitchen drains

"Cleared blockage in kitchen drains, checked all drainage in bathroom and kitchen, problem solved! Engineer was there next day and sorted problem within a few hours. Super great value and service"

Bathroom sink unblocked

"I attempted to unblock our bathroom sink using a plunger, then sink clearing chemicals and finally removing and confirming the u-bend was clear, all to no avail. I went on the Checkatrade website and found Happy Drains. I called and booked a plumber to come the following day. The plumber arrived as expected, was professional, polite and got to work straight away. He cleared the blockage that was further down the pipework using a wet vacuum within 10 minutes. It's been perfect ever since."

5* Service was Over and Above expectation.

"This is the second time I have used Happy Drains the Service provided last time was superb. This time it was even better! With no appointments available to clear my elderly mothers blocked toilet, Happy Drains rearranged a schedule to conduct the work to limit inconvenience. 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."
