Drainage engineer clearing a blocked drain using professional unblocking equipment

Trenchless Repair Specialist

Drain Unblocking & Cleaning

A blocked or slow-running drain doesn't need to mean a dug-up garden. We clear blockages, mud, and silt build-up efficiently, with minimal disruption to your property.

A blocked drain rarely announces itself politely. It's a sink that won't empty, a toilet that gurgles, or standing water where there shouldn't be any. Left alone, mud and silt build-up gets worse, and what started as a slow drain can turn into a full blockage or back-up.

You need it cleared properly — not just pushed further down the pipe to reappear next month. Flux Sewer's drain unblocking and cleaning service removes the actual obstruction, whether that's a solid blockage, accumulated silt, or a general restriction, using professional equipment suited to the job.

What's included. We clear blocked drains caused by solid obstructions, mud and silt build-up, and general restrictions, using professional drainage equipment to remove the blockage rather than just shift it. Where the cause isn't obvious, we can follow up with a CCTV survey to confirm exactly what's happening in the pipe.

Why customers choose Flux Sewer for this. Our team brings over 10 years of industry experience to blocked drain jobs, so we're working from experience rather than trial and error. We use modern equipment to clear drains efficiently and with minimal disruption to your property — no need to dig anything up for a straightforward blockage.

How the process works. You describe the problem when you get in touch, and we arrange a visit at a time that suits you, 7 days a week. Our engineer locates and clears the blockage using the appropriate equipment for the type of restriction. If the blockage is a symptom of a bigger structural problem, such as a cracked pipe or root ingress, we'll flag it and recommend a CCTV survey before any further work.

Who this service is for. This service suits homeowners with a blocked sink, drain, or toilet, and property owners or landlords dealing with mud or silt build-up in an older drainage system, or a drain that's become gradually more restricted over time.

Our approach. Every job comes with a free quotation, and we're fully insured throughout. Where a blockage keeps recurring, we'll always tell you honestly if it points to a deeper issue rather than just clearing it again and again.

How It Works

01

Diagnose the blockage

We identify the type and location of the blockage, using a CCTV survey first if needed.

02

Professional clearance

Using specialist equipment, we clear the drain thoroughly rather than just pushing the problem further down the line.

03

Flow test

We test the drain to confirm the blockage is fully cleared and water is flowing freely again.

04

Prevention advice

Where useful, we'll offer simple advice to help reduce the chance of the same blockage recurring.

What Our Customers Say

“Reliable, well-intentioned, friendly service, fair costs with specialist knowledge, up-to-date gear and technology equipment. Highly recommended.”

Helga E-3

via Yell

“I'm just finishing off a ten year refurb of my 1850s cottage, so I have some experience with engaging contractors to handle the jobs I can't/am not allowed to. It seems to be rare these days to find businesses that are at the same time competent, prompt, flexible, efficient, tidy and reasonably priced. I'm happy to say that this was the case with Flux Sewer – Ben and his team went out of their way to accommodate my wishes as they constructed a new drain for my property. I would unreservedly recommend them to anyone who needs any drainage work done.”

Rob Buttress

“I don't give out 5* lightly. Fantastic service from 2 honest blokes. Fast, efficient, and actually came in cheaper than the quote. Ben decided that some of the work I had asked for a quote on didn't need doing. Both the guys who came were polite, well-spoken and friendly. My drain was repaired quickly and cleanly, and as I said, cheaper than the original quote, which was already considerably cheaper than the quote I had from another company. I would highly recommend Ben and Flux Sewer Ltd.”

Richard Hallett

via Google

“Really professional and efficient service. The issue I had was a long term problem that the former owner of my property had employed numerous companies to address but never resolved. Flux diagnosed the issue, fixed the problem then spent time mapping and clearing out the damaged pipes so an ongoing maintenance routine can be implemented to manage an issue that will always exist, but can now be controlled by simple routine procedures. I am really happy with the outcome and will now use the Flux team again to help manage the rest of my complex Georgian water supply and drainage system.”

Neil Emery

Sally Emmerton

Ben was very professional, and overcame issues as they arose by giving clearly explained and quoted solutions. Provided a written report including videos to catalogue work done. Highly recommend.”

Kate Berwick

via Google

“Found Ben and his team very professional and efficient. Details of the problem and what needed to be done was explained clearly, found them very friendly and reassuring, leaving the area clean and tidy, and the price was very reasonable. Ben and his team made good the bad work a previous company had done. We would not hesitate to recommend Flux Sewer.”

Kerry

“Having Flux Sewer work in my home in Devon has been a pleasure! My first telephone contact with Ben was really excellent, quickly organising a competitive quote and work completion. Always swift to respond, and the team completed the renovation of my pitch fibre pipes to a very high standard. By being friendly, prompt, reliable, clean and respectful, they are definitely the professionals in the drainage repair business. A+++ recommendation for Flux Sewer Ltd from me!”

Andy King

“We had an issue with our drains backing up due to a reduction in the size of the soil pipe, as it's an older property. Ben came out and surveyed the pipe work with his camera, before returning and replacing a length of pipe and benching the manhole. He always arrived when he said he would. Very polite, worked quickly and efficiently, and the cost of the repair was reasonable. Very pleased.”

Alan Tobey

Ben Ryder

“Great service from Flux Sewer Ltd! Ben arrived quickly and diagnosed our problem with the help of a camera down the drain. The excavation and repair was carried out a few days later with minimum disruption or noise, and the guys left everything clean and tidy. I can highly recommend Flux Sewer.”

James Egan

“From coming on the site to quote for the drain work, which was accepted, they were very professional and gave good and sensible advice, which saved a lot of money. They are clean, tidy and respectful to the work and the client. Thank you Ben, and we must not forget the team who worked long and well.”

Mike Sowden

“Very highly recommend Flux Sewer. We needed a new drain cover and ground repair in one of our school playgrounds. Ben was quick to reply — quickly quoted (at a very fair price) and booked in to complete the job, all within a few days. Great job done and a pleasure to deal with — we will definitely use them again for any similar work at our schools, and recommend Flux Sewer to everyone. A really professional company that communicates well, does not overcharge, and turns up when they say they will.”

“Flux Sewer did an excellent job of relining our pitch fibre pipe without undue fuss. James and Ryan were a pleasure to have working for us — they were polite, cheerful and highly professional in constantly letting us know what was happening. They also left the site clean and tidy. In the run up to the work, Ben was very good at staying in touch — arranging the job couldn't have been easier. Having done some research, their price was very reasonable considering the complexity of the process and the high-end kit used. Not forgetting how much digging up the pipe would have been avoided! I can highly recommend Flux Sewer if you need pitch fibre pipe relining — you won't be disappointed.”

Common Questions About Drain Unblocking & Cleaning

Not for a standard blockage. Drain unblocking and cleaning is typically carried out through existing access points, with no excavation required.
