Reliable service for unblocking drains
Prompt service, work carried out with minimum fuss, at fair cost.
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.
Customer in Chingford
Good service and fixed the problem.
Happy Drains did a great job, it was easy to book an appointment with them over the phone, their engineer got in touch direct he arrived on time and had the blocked drain fixed with no fuss. Also the price was really good and payment was made easy via the payment link/website. I would definitely recommend Happy Drains ?'? Justin

Why do blockages happen? Please read our blogs, but Mansion House drains and pipes are designed to be self-cleaning. However fat, oil & grease (known as FOGs in the trade) accumulates on Mansion House drain pipe walls, and is often the cause of many blockages. We remove the FOG or obstructions, and we can clean the drain pipes to restore the maximum of flow.

Blocked drain that runs under house.
"Had a blockage from the sink drain that runs under my house. Called at 9:05 and engineer arrived within 3 hours and got the problem sorted within 25 mins of arrival making myself and my drain happy.
