External Drain Unblocking across Banbury

External drains carry waste and rain water from your property to the public sewer. They include gullies, manholes and underground pipe runs. Leaves, soil, moss and tree roots build up in them over time.

Because the pipes sit underground, problems often go unseen. Then water pools in the garden, rises in a manhole or backs up into the house. Foul smells near a drain cover are another warning sign.

The engineer uses high-pressure jetting and drain rods to clear the blockage. A camera can then check the pipe for cracks or roots. As a result, you learn whether the drain needs repair as well as cleaning.

Signs you need external drain unblocking help

These are common signs that you need external drain unblocking. If you spot one, act early, because small faults often grow.

✓ Water pooling around external drain covers, gullies, or in the garden after rainfall
✓ Manhole or inspection chamber covers have water sitting at or near the surface
✓ Foul smells outside your property, particularly near drain covers or gullies
✓ Slow drainage from internal fixtures that share the same underground pipe run
✓ Visible sewage or waste water surfacing in the garden or driveway

Our process

These steps show a typical visit. However, the exact method depends on what the engineer finds on site.

1.
Locate and Access
We identify all external access points — manholes, inspection chambers, and gullies — and open them to assess water levels and flow direction to pinpoint the blockage location.
2.
High-Pressure Jetting
Our jetting unit feeds a high-pressure hose into the blocked pipe section, blasting through the obstruction and scouring the pipe walls clean as it progresses.
3.
CCTV Check
Where appropriate, we run a camera through the cleared pipe to verify the blockage is fully removed and check for structural issues such as root ingress, cracks, or displaced joints.
4.
Restore and Report
We refit all access covers securely, clear any surface debris, and advise you on the condition of your external drainage and any maintenance or repairs that may be beneficial.

Pricing guide

The price depends on how much pipe is affected and what is blocking it. Tree roots or packed debris may need longer jetting. Send a request online and we pass it to a local engineer, who confirms the price before starting.

External Drain Unblocking — frequently asked questions

Who is responsible for external drain blockages?

You usually own the private drains within your boundary. Shared sewers and public drains beyond it are the water company's job, which is Thames Water in the Banbury area. If the blockage is in a public sewer, the engineer can tell you how to report it.

Can tree roots cause external drain blockages?

Yes, they are a common cause. Roots seek out moisture and push into pipe joints and cracks. They then grow inside the pipe until water cannot pass.

How often should external drains be cleared?

For most homes, a yearly check and clean is enough. However, homes with large trees near the drains may need a visit more often. Past blockages are another reason to check sooner.
