Customer in Kilburn
Highly recommend.
Called Happy Drains as although drain wasn't blocked it was smelling and there were drains flies. Excellent communication from all, keeping me informed as to time etc. They came the next day, on time, and hosed the drains out. Very nice guy, did the job efficiently, left drain clean and running freely, and within a few days 99% of the drains flies were gone. Highly recommend.

I used Happy drains to survey the drains of the house I bought in Kew Gardens SW London. From the initial phone call they were professional and efficient and friendly. The guy turned up on time, very professional and knew his stuff. Turnaround of the report was super quick, it was comprehensive, and included video and was easy to share with the estate agent . It gave me peace of mind to continue with the purchase. They were competitively priced and I would highly recommend

very efficient service. Fixed price quoted over the phone and invoice received by email. As promised, I received a call to tell me he was on his way. Once he arrived he got on with the job, with the minimum fuss, cleared the drain, thoroughly tested to make sure it was completely clear and left with no mess.

I called Happy Drains to attend to an overflowing drain manhole in our front drive. Their response on the telephone was prompt, courteous and helpful. Their engineer arrived slightly earlier than arranged, after telephoning to confirm that this would be acceptable. He fixed the problem in less than 30 minutes, and checked that everything was satisfactory before leaving.

Drain issues
We booked in a clean because our drain in the back garden smelled like rotting eggs. The technician took off the manhole cover and could see it was completely blocked. He had all the tools on hand to unblock the drain and it looks sparkling now. He was very knowledgable and we learned a lot about Victorian drains! Would definitely use again!

Very easy to organise the appointment to unblock a drain that we had tried and failed to clear ourselves. They were reasonably priced, stuck to their quote, the engineer was very personable, paid for their own parking and explained the issue! That's all I ask from a service company.
