Drainage Services in Stockton-on-Tees

Quick answer: Drainage clearance in Stockton starts from £80 depending on the blockage type and location.

Drainage in Stockton-on-Tees

Blocked drains are a common issue in Stockton, and the problem varies depending on where you live and how old your property is. Victorian terraces in the town centre and Norton often have original cast iron waste pipes that corrode and narrow over time, making blockages more frequent. The 1960s-70s estates around Fairfield and Bishopsgarth typically have basic plastic waste systems that work fine until grease, hair, and soap scum build up. Larger detached properties in Eaglescliffe and Hartburn usually have more modern drainage, but they’re not immune to problems. Modern developments in Elm Tree have well-designed systems, but misuse still causes blockages. Town centre terraces occasionally have shared drain runs between neighbouring properties, which complicates diagnosis when multiple households are affected.

We diagnose the blockage location, clear it using the right equipment, and check everything flows correctly before leaving. Most jobs take 30-60 minutes depending on severity.

Common Drainage Problems We Fix

Hair and soap scum build up gradually in bathroom drains, particularly shower trays and baths. Hair catches on rough pipe surfaces or minor damage inside the waste pipe, then soap and shampoo residue stick to it, creating a mat that blocks water flow. This happens slowly over months until the drain suddenly stops clearing.

Grease and fat are the main cause of kitchen sink blockages. Washing-up liquid emulsifies fat when it’s hot, so it flows down the drain. Once it cools in the pipework, it solidifies and coats the inside of the pipe. Over time, this narrows the bore until water can’t pass. Food debris sticks to the grease, making it worse.

Limescale builds up in hard water areas, particularly on older pipework. It reduces the internal diameter of waste pipes gradually, making blockages more likely even with normal use.

Foreign objects—cotton buds, wipes, sanitary products, small toys—get flushed or washed down drains and lodge in traps or bends. Even “flushable” wipes don’t break down like toilet paper and cause blockages in waste pipes.

Tree roots usually affect external drains, but if your internal pipework has cracks or poor joints near the property, roots can find their way in. Once inside, they spread and block the pipe completely.

Collapsed or damaged pipes occur in older properties where cast iron or early plastic pipes have deteriorated. Ground movement, corrosion, or poor installation cause sections to sag or crack, creating low spots where debris collects.

When to Call a Plumber vs DIY

If you’ve tried a plunger and it hasn’t worked, or if multiple drains are affected at once, call us. Recurring blockages need proper diagnosis—there’s usually an underlying issue that DIY methods won’t fix. If you can see or smell sewage, don’t use the affected drains and call immediately. Chemical drain cleaners rarely work on serious blockages and can damage old pipework, making repairs more expensive.

Our Drainage Process

We start by identifying which drain is blocked and where the blockage is located—trap, waste pipe, or further downstream. Visual inspection comes first, then we use hand tools, powered augers, or jetting equipment depending on what’s needed. Once the blockage is cleared, we run water to check flow and make sure nothing else is restricting drainage. If we find damage or recurring issues, we’ll explain what’s causing it and what options you have. Simple blockages take 30-45 minutes. Complex jobs with multiple affected drains or pipework issues can take 1-2 hours.

CCTV Surveys and Jetting

Recurring blockages or multiple affected drains usually need a proper inspection. CCTV drain surveys let us see inside accessible pipes to identify root ingress, collapsed sections, scale build-up, or incorrect falls. The camera shows exactly where the problem is and what’s causing it, so we’re not guessing.

High-pressure jetting clears roots, hardened grease, and scale that manual methods can’t touch. The jetting unit sends a powerful water jet through the pipe, blasting debris off the walls and flushing it downstream. We use this when hand tools don’t work or when the blockage keeps coming back. It’s particularly effective on grease build-up in kitchen waste pipes and light root intrusion.

Internal vs External Drains

We specialise in internal drainage—the waste pipes from your sinks, basins, baths, and showers running into the soil stack. This covers everything inside your property and the immediate external pipework connected to it.

For main drains, external sewers, or deep underground work beyond the soil stack, we’ll recommend a specialist drainage contractor with excavation equipment and full survey capabilities. They have the kit and insurance for digging up gardens, driveways, and shared sewer lines. We’ll tell you honestly if your problem is outside our scope—there’s no point attempting work we’re not equipped for.

Coverage Across Stockton

We cover all Stockton-on-Tees postcodes including Norton, Fairfield, Hartburn, Bishopsgarth, Elm Tree, Eaglescliffe, Thornaby (TS17), Yarm (TS15), Ingleby Barwick (TS17), and the town centre. Victorian terraces through to executive homes—we work on the full range of Stockton’s housing stock.

Prevention Tips

• Fit sink strainers to catch food and debris before it enters the waste pipe
• Never pour fat, oil, or grease down sinks—bin it once cooled or save it in a container
• Run hot water through drains after washing up to keep pipes clear
• Remove hair from plug holes weekly, particularly in showers and baths
• Don’t flush wipes (even “flushable” ones), sanitary products, cotton buds, or dental floss
• Address slow drains early before they fully block—it’s cheaper and easier
• Pour a kettle of boiling water down kitchen sinks monthly to help dissolve grease build-up

My shower tray fills up when I shower—can you fix that?

Yes. Shower trays filling up means the waste pipe is blocked or the fall isn’t adequate. We’ll clear any blockage first, check the trap and waste run, and advise if pipework needs adjusting. Most cases are simple blockages that clear quickly. If the pipe run has the wrong fall or there’s a design issue, we’ll explain what needs changing and give you a price for the work.

The kitchen sink drains fine but smells bad—what causes that?

Usually a dry or partially blocked trap. The trap (U-bend) holds water to stop drain smells coming up. If it dries out or has debris sitting in it, you’ll get odours. We’ll check and clean the trap, flush the waste pipe, and identify any venting issues. Sometimes the trap needs replacing if it’s damaged or incorrectly fitted. Persistent smells can also indicate a problem further downstream in the waste system.

Can tree roots get into internal drains?

Roots typically affect external drains and sewers, but they can occasionally reach internal pipework if there are cracks or poor joints near the property. Victorian properties in Norton and the town centre are more vulnerable because the original pipework is often damaged or deteriorated. CCTV surveys identify root intrusion, and we can clear accessible sections with jetting or cutting equipment. Severe root problems usually need pipe replacement.

What’s high-pressure jetting and when is it needed?

High-pressure jetting uses a powerful water jet to blast through grease, scale, roots, and compacted debris in pipes. It’s needed when manual clearing doesn’t work or when blockages keep recurring. The jetting unit forces water through the pipe at high pressure, removing build-up from the pipe walls and flushing it downstream. We’ll assess and recommend jetting if hand tools won’t solve the issue. It’s particularly effective for kitchen waste pipes with heavy grease deposits.

Do you clear toilet blockages?

We handle toilet blockages as part of drainage work. If it’s a simple blockage in the pan or trap, we’ll clear it. If the soil stack or main drain is blocked, we’ll assess whether it’s within our scope or needs a specialist drainage contractor with full excavation capabilities. Most toilet blockages are straightforward and clear within 30 minutes.
