Sewer Cleaning in Glasgow

A sewer carries the combined waste from all the drains in a property, or in the case of a shared sewer, from all the properties connected to it, and moves it toward the public sewer network. When a sewer blocks or builds up with grease, silt and debris, it does not just affect one sink or one toilet. It affects every fixture connected to that sewer line. In a tenement close, that can mean every flat in the building. In a commercial property, it can mean the whole site.

Sewer cleaning is different from clearing an individual drain. The pipe diameter is larger, the run is longer, the access points are manholes and inspection chambers rather than plughole traps, and the consequences of a blocked sewer are more serious than a blocked sink. Sewage backing up into a garden or flooding a commercial kitchen through a floor drain is a health emergency as much as a drainage problem.

ClearFlow clears and cleans private sewer lines and shared sewer runs across Glasgow and the surrounding area for domestic properties, tenement closes, HMOs and commercial premises. David and Chris identify the blockage location, confirm whether it is on a private or public sewer and clear it properly on the first visit in the large majority of cases.

Signs you need sewer cleaning

  • Multiple drains, toilets and sinks in the property all draining slowly at the same time

  • Gurgling sounds from toilets or floor drains when other fixtures are used

  • Sewage smell inside the property coming from floor drains, toilet bases or inspection chambers

  • Manhole or inspection chamber in the garden or back court showing signs of surcharging

  • Sewage backing up into ground floor toilets or showers when upstairs fixtures are used

  • Neighbouring properties in the same close or on the same connection reporting the same problem

  • Sewer line that has not been cleaned or inspected in several years

  • Commercial premises where floor drains are slow or backing up during peak kitchen or trading hours

Our process

  1. 1

    Call or message us

    Speak to David or Chris. Tell us how many properties or fixtures are affected, whether a manhole is surcharging and the best access point. We confirm the price and the approach before we travel.

  2. 2

    Price confirmed in writing

    You get the price by text or email before the engineer sets off. No call-out fee, no extras for access or for longer sewer runs.

  3. 3

    On site fast

    Emergency sewer callouts get the same 15 to 45 minute response as indoor drain emergencies across Glasgow. Planned sewer cleaning we schedule at a time that suits the property.

  4. 4

    Locate the blockage and clean the sewer

    We lift the manhole or inspection chamber lid and use CCTV to establish where the blockage is and whether it sits on a private drain, a shared sewer or Scottish Water's public sewer. If it is on the public sewer we tell you immediately and explain the reporting process. If it is on a private or shared sewer, we clear it using high pressure jetting at up to 4,000 PSI, which removes grease, silt and debris from the full bore of the sewer run.

  5. 5

    Inspect and confirm

    We run the CCTV camera after jetting to confirm the sewer is fully clear and note the condition of the pipe. If we find root ingress, a collapsed joint or any structural issue we explain what we found and provide a written quote for the appropriate repair.

Common causes

What Causes Sewer Blockages in Glasgow?

Sewer blockages in Glasgow follow predictable patterns based on the age and type of the sewer, whether it is a domestic, shared or commercial connection, and what the connected properties have been putting into the system. Here are the most common causes we clear every week.

Wet wipes accumulating in shared sewers

The most common cause of blocked shared sewers in Glasgow's tenement properties. Wet wipes do not break down and collect at every bend and joint in a shared sewer until the bore is completely blocked. A single flat putting wipes down the toilet contributes to a blockage that eventually affects the whole building.

Fat, oil and grease from kitchens

Cooking fat enters the kitchen waste pipe and reaches the sewer where it solidifies and accumulates. In commercial properties connected to a shared sewer without properly maintained grease traps, the volume of FOG is much higher and blockages develop faster.

Root ingress from street and garden trees

Glasgow's older streets have large, established trees whose roots have had decades to find joints in clay and cast-iron sewer pipes. Root ingress in a shared sewer affects every property connected to it.

Silt accumulation in low-gradient sewer runs

Older sewer runs in Glasgow's pre-war housing stock were laid at gradients that have changed over time as ground movement settled pipe sections. A reduced gradient means silt settles rather than being carried through to the public sewer.

Collapsed or displaced sewer joints

Clay sewer pipes under Glasgow's older streets crack and displace from ground movement and vehicle loading. A displaced joint creates a step in the sewer bore that catches wipes, grease and debris.

Combined sewer overloading in heavy rainfall

Parts of Glasgow have combined sewers that carry both foul water and surface water. In very heavy rainfall the combined load can exceed the sewer's capacity, causing surcharging at the nearest manhole even without a conventional blockage.

Good news: every one of these has a clean, proven fix, and we'll show you exactly what we found.

Why choose ClearFlow

Local and owner-run

David and Chris are Glasgow-based and respond personally to every sewer callout. You speak to the engineer on the phone, not a scheduler.

We identify responsibility first

We tell you on the callout whether the blockage is yours, shared or Scottish Water's. You are not paying for work that belongs to someone else.

£5M+ public liability

Fully insured on every sewer cleaning job, domestic and commercial. Certificate available on request.

CCTV before and after

We inspect the sewer before clearing to locate the blockage and after clearing to confirm the result. You see the footage.

Fixed price, no emergency surcharge

Confirmed before we start, including on emergency callouts. No extra charge for nights, weekends or bank holidays.

Shared sewer experience

Tenement closes, HMOs and shared private sewers are second nature to us. We deal with them across Glasgow every week.

What We Use for Sewer Cleaning

High pressure water jetting at up to 4,000 PSI is the primary method for sewer cleaning. Run from the inspection chamber or manhole downstream, jetting removes grease from sewer walls, breaks up wipe accumulations and flushes silt from the full bore of the sewer run. It cleans the pipe, not just creates a channel through the blockage.

Mechanical rodding and root cutting equipment handles solid blockages and root ingress in the sewer bore. Root cutting is combined with jetting to remove the root mass and flush the debris downstream. After root cutting we always recommend a CCTV inspection to assess the joint condition where the root entered.

HD CCTV cameras with distance metering give us a live view inside the sewer from the inspection chamber. We see the blockage location, the cause and the structural condition of the pipe in one pass. We show you the footage and provide a written report if one is needed for insurance, legal or property sale purposes.

Transparent pricing

No call-out fee on sewer cleaning callouts. The price is confirmed in writing before we start. No extras for access, for longer sewer runs or for shared sewer work involving multiple properties.

If the blockage turns out to be on Scottish Water's public sewer, there is no charge for identifying that and advising you on the next steps.

If the post-cleaning CCTV shows a structural repair is needed, we provide a separate written quote. Nothing proceeds without your agreement.

Reviews

What Our Clients Say

Real reviews from Glasgow households and businesses we've helped.

"I had major issues with my drainage caused by ground movement. The ground had to be dug up and a new drainage system put in. This was done efficiently and to a very high standard, the workmen were legends, absolutely brilliant. My slabs were all put back exactly as they were before. I highly recommend this company."
