Drain flushing
"Arrived on time and was very polite and professional. Did what he needed to do with the minimum of fuss and explained what he had done along with verbal recommendations as to the next steps. This was followed up promptly with an email report."
Blocked drain
"Happy drains was very courteous right from 1st phone call to completion. The man that came was very professional, helpful. Cleaned up after himself and carried out several checks and didn't leave until he was satisfied the job was complete. I would highly recommend happy drains.. Thankyou. "
Unblock drain re kitchen sink
"Happy Drains sent Alex who was superbly focused and dedicated. He rapidly identified the blocked kitchen sink that had not been resolved by a plumber was a drainage issue (as suspected), found the drains, identified the correct one linked to the kitchen, sent a camera down to find the blockage, and rinsed it away with high pressure water jet. Took an hour, with a lot accomplished. No additional or unexpected charges. Very happy with their service and professionalism (given dealing with these sorts of issues can be a minefield of distrust)."

Rats, mice, rodent and vermin drain problems
Rats will use drains just like ‘Londoners use the Tube’ simply to travel from A to B to feed and nest and they love damaged or redundant drainage systems which can allow vermin to enter properties.
If you have a rodent/vermin infestation that your rodent/vermin contractor cannot control, this may be because of a drainage issue. We will find the defects and access points the rat may be using. We will offer you an appropriate solution be it drain repair or the installation of a WRc tested and certified 'Anti Vermin / Non-Return Valve'.
What do our Anti Vermin/Non-Return Drain Valves do?
- Stops rats and other vermin from entering homes. In effect by fitting a stainless-steel flap, that acts as a one way swinging door allowing waste out but nothing back in.
- The rubber seal prevents noxious fumes and smells from entering properties.
- The flap has an inbuilt stainless steel plate to stop rodents biting through, providing efficient pest control.
- The valve is completely re-usable during any drain cleaning and drain maintenance purposes fully removal and re-usable.
- Stops backflow of effluent from a blocked main sewer flooding into your property back through the drainage system.
- The clever design means the flow of waste is increased when passing through the valve; reducing blockages.

Blocked Drain
"Happy drains were great from start to finish! They had immediate availability to come to my house and sent a super helpful tradesman called Darren who quickly unblocked the drain and showed me how to do it myself in future. Highly recommend!"
The main drain from bathroom blocked. Backed up to kitchen drain.
"This was my 87 yr old mother's house. We lifted the manhole cover thinking maybe we could unblock it, but it was full. So any water drainage was just overflowing. Euch!! A neighbour recommended Happy Drains. Phoned them about 9.30 Saturday morning. They were with her by 6. They kept in contact all day to let us know the expected arrival time. Super friendly, excellent communication, good price. Great service, especially for my elderly mum. Thankyou"
Clear my kitchen drain
"Same day. Curteous, knowledgeable local. Fast , clean, very pleasant guy. Invoice follows. Price as quoted, would highly recommend."
Clear blocked trap in drain and slow draining sink and shower
"On time, efficient and thorough assessment and ensured all aspects of the problem were resolved. "
Foul smell in bathroom
"I had a disgusting smell of sewage coming through my pipes in the bathroom, after trying to solve the problem myself unsuccessfully i called Happy Drains and Alex arrived as planned, as soon as he flushed the loo he knew instantly what the problem was - a blockage in the pipes. To say he solved my problem is an understatement, he went to both of my neighbours to check their drains until he found the blockage and then went ahead and flushed the pipes through. He was a true gentleman, polite, funny and very caring. I highly recommend this company and especially Alex. Thank you Alex"
Clear Kitchen Drain
"Very polite from asking if it was okay to park on the drive to explaining what the problem was, what he planned to do, showing the camera footage & clearing up & explaining guarantee. Invoice came through with amount advised. Would definitely use again. "
Drain clearance
"Excellent service. He phoned to let me know he was coming, and then cleared the drain very quickly and professionally. He cleared everything up after he had finished. Would highly recommend "
Clearing drain blockage.
"Engineer arrived on time, he was very polite and worked quickly. He explained everything he had done to me and made sure I was perfectly happy before he left my house. I will definitely be recommending Happy Drains to my family and friends and would not hesitate to use them again."

Clearing of bathroom drain.
"Exceptional experience with this company! The booking process was seamless. Communication with the company was very clear on scheduling and having costs upfront meant no lingering worry on the final bill. Work was done quickly and the technicians were very professional. Payment was smooth as well (was able to use Apple Pay). Will definitely get my business again if needed and will recommend them to anyone else in the same situation."
Great communication and fixed price drain clearance
"From the first phone call enquiring about drain clearance with Emily to the actual work being carried out was less than 3 hours. I knew immediately upfront what the cost would be and how much extra if a Saturday call out was needed. I was kept informed by phone and email and received a call from the engineers 30 mins prior to arrival. They very quickly identified and cleared the problem clearing up any slight mess they made. Hope not to need this service again but if I do would Happily use Happy drains again."
Drain was blocked - required unblocking.
"Happy Drains make it easy to arrange getting a blocked drain unblocked. We have used them several times and would highly recommend them. The communication is helpful, friendly and information is reliable. Once job is done, feedback is received which would help should a future problem arise. "
Kitchen Gully Cleared
"Fast and reliable service, called at 9am and engineer was at my property within 2 hours. The engineer was super friendly and explained the reasoning behind our issue, whilst tidying up after himself. Very reasonable pricing too. Would recommend. "
