No fuss. On time. Job done.

"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. Thank you Happy Drains."

Unblock outside drain

"We are very happy with the service from first phone call through to the fixing of the problem. Such friendly helpful and professional staff. I will retain the phone number if needed again and certainly will be recommending Happy Drains company. "

Unblocking drain

"From when you call them, you are dealing with a real person and with that comes efficiency. Very polite on the telephone and also the drain engineers on site were very polite and just got on with the job. They showed you the unblocked drain before leaving the site and explained what I would receive in the report via email. Thoroughly recommend them and very good value. For the amount of crap they have to unblock each day, the service is spotless."

Unblock an outside pipe

"Unfortunately the pipe was blocked with concrete which appears to have happened when the garden fence was erected. However, the tradesman wrote the reason it was blocked on the invoice which helped when I contacted the tradesmen who erected the fence."

Drain camera inspection

"All staff were professional, friendly and helpful. The drain survey was conducted promptly, and the report received in good time. The report was thorough and helpful."

Downstairs loo and sink unblocking, by jetting upstream from manhole in the garden.

"Brilliant. From the first phone call to saying goodbye. Job explained, job completed and everything works perfectly. The young guy called Tommy from Sunbury was top drawer. Going to do this jetting annually now."

Drain cleared

"Happy Drains contacted me within minutes of posting my requirement. Their communication was always very clear, and the one time I misunderstood something, they immediately contacted me by phone to politely correct my error. The plumber contacted me by phone to give me 20 minutes notice of his arrival. On arrival, he immediately assessed the situation, and rectified it using equipment within the vehicle. The whole process took just minutes, and he explained the causes of the issue to me. At the same time he checked all other connected drains and made good the area."

Toilet unblock

"Came and sorted it quickly, helped me realise how easy it would be to do by myself in the future and checked that water was flowing freely outside. Did a good job by all accounts. "
