Second time using Happy Drains. Booked them for a CCTV drain survey following an unsatisfactory experience with another provider; they had originally been engaged when we bought the house and came recommended again through a trade contact. The engineer arrived punctually, was courteous throughout, and walked us through the findings on site. Pricing was fair, an the final invoice matched the quote. The written report and accompanying video footage contained enough detail to understand the condition of the drain runs and scope the remedial work. Will be using them again for the corrective works.
