Drain clearance at home
"We had an excellent experience with Happy Drains. We called in very worried about an overflowing gully, they sent a specialist over the next morning and he fixed our problem with no fuss even though it was not completely straightforward. He took initiative and solved the problem. He notified the sewer company as well who came just two days later to fix things on their end. (Though as far as our issue went it was already fixed on day 1!) it took less than an hour and we're very happy with the result! Smooth and professional process throughout, we would highly recommend them."

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.
Building an extension?

A few more excellent reviews to reassure you...

Drain clearing
"Great quick service, photos sent of clearance, good prices, easy to contact. Would recommend and use again"
Clearance of a blockage at bottom of soil stack (Berkshire)
"Excellent service. I had previously tried another well known national contractor, but they lied about sorting the problem and their followup customer service was poor. HOWEVER Happy Drains enginners were friendly, competent and explained everything they were doing. Ultimately they sorted out what was a difficult to reach blockage underground, where the previous company had failed. I would not hesitate to call Happy Drains first if/when the need arises in future."
Clear blocked drains
"I'm a very satisfied customer. They can when I asked, arrived on time. Took time to hear my problem and set to the task. They had it done in a jiffy, but took the time to ensure other drains where not effected."
Drain clearing as water backing up in kitchen
"Excellent service. Extremely efficient and professional. Cleared the problem quickly and I was very impressed by the fantastic customer service. I would highly recommend Happy Drains."
Blocked kitchen drain, cleared.
"Fantastic service and a job well done. Our waste pipe in the kitchen was overflowing. I called Happy drains at around 2:30pm, the engineer arrived, fixed the problem and had gone by 3:45! Great service!"
Clearing a blocked / slow draining kitchen sink
"I called Happy drains regarding my blocked sink which has started blocking my dishwasher too.I think I must have spoken to Emily at Customer service and she was very polite and explained the process to me. I got a plumber in my house in less that 2 hours! He managed to unblock the pipes super quick and made sure to clean any spillages left after. I am extremely happy with the service I have gotten as I am always so scared that am going to be overcharged over something I don't understand. The process was simple, affordable and quick. I would recommend and go back if needed."
Drain blockage
"Great job! Quick to answer the phone and to send someone out. Price quoted was price paid. Highly recommended!"

Blocked combined system.
"Second time using this company, once at a business address and now at home. Enquired Saturday evening, automated response to advise they would call Monday to arrange a visit. Turned up same day and had the issue resolved without fuss and cleaned down the paving. Would highly recommend!"
Drain blockage
"Prompt service problem solved within 45 minutes very happy with the service and cost."
Unblock Drain
"Really pleased to use a local firm. Their quote was given straight over the phone, which was a lot less than a large national company used some years ago. Really quick (less than a couple of hours), really friendly. They definately deserve the excellent reviews that have been left on this website."
Cleared blocked drain
"Very good service. An appointment was made for the following day and the drain was cleared quickly and efficiently and the site left tidy. Would use again and recommend to others."

Our London CCTV drain surveys, unblocks and repairs get great feedback...

Patch repair and replace a section of pipe where it had dislodged
"Following initial cctv inspection, repairs were found. A comprehensive report, with the cctv footage was sent out after I had paid for the inspection. A chap called Jason was extremely helpful in guiding me through the report. Si, the engineer who came out to do the repairs was a nice chap, very helpful and talked me through all aspects of the job. I must say the quote part of the report that comes from head office made the job sound a lot bigger than it actually was. I think next time I would consider paying for the cctv inspection and report and getting other quotes for the work to be done."

"Convenient, fast appointment. Problem identified and fixed with their high power equipment very efficiently. Friendly and reliable. Would use again and certainly do recommend."

"I couldn't be more pleased with the service I received from Gordon and Tommy. They were polite, efficient and knowledgeable.

"Would thoroughly recommend Happy Drains. Gordon and Tom were the nicest people, incredibly helpful, hard working, polite, friendly.... They were both brilliant and went above and beyond to help us out. Their prompt arrival (within 2 hours of the initial call) was an added bonus - especially on a bank holiday! Excellent!"
Blocked stack pipe.
"We had a blocked drain but couldn't rod it or find where the blockage was, it was inaccessible to us. Called Happy Drains and spoke to Rachel who was very helpful and someone was here in about 15 minutes as they had just finished a job nearby, that was amazing in itself! The guys located the problem area quickly and kept us updated, they were very friendly. They sorted the issue and also provided rodding access should the problem arise again as it is a potential problem area. Superb service and reasonable rates, would happily recommend them. Thanks!!"

Been using these guys for drain surveys in the construction industry for years but first time actually using them for clearing a blockage...was affordable, super quick and will go back to them for certain. Oh, and you don't have to pay up front which is nice, they seem to focus on customer service rather than the commercial side of the business...very rare these days."
