1st time customer - Excellent experience
"1st time using Checkatrade. Polite and efficient experience from beginning to end, with clear/ transparent pricing + quick availability of plumber. I chose to use Happy Drains... who were available same day to unblock kitchen sink. Damian from Happy Drains was friendly and cheerful, but always polite and professional and persistent with unblocking drain. Damian had a powerful acqua vac that was required to unblock the drain. Not an easy job, but Damian persisted and determined to get job done. No surprises with charges...exactly as quoted and very reasonable. Recommended."
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."
