Drainage Services Charlton
Blocked drain clearance, CCTV surveys and no-dig relining for Charlton homes, from engineers who know Charlton buildings.
Local knowledge
Charlton housing, from a drainage engineer's side
Charlton's housing stock is a blend of Victorian and Edwardian terraces, 1930s semis, and post-war estate housing, often on sloping ground towards the Thames. This topography influences drainage flow and pressure. Many properties have been extended, placing additional load on original drainage layouts not designed for modern bathroom and kitchen volumes.
Engineer's note
The technical gradient data we provide is often critical for planning applications for basement conversions in Charlton's sloping terrain.

What fails here
Common drainage problems in Charlton
01
Drainage Run Deformation on Slopes
Drains on steep gradients can suffer from 'belly' formation or joint separation due to soil creep over time. This creates sediment traps and recurrent blockages. Our CCTV surveys include gradient analysis to identify these deformations, classifying them as WRc defects for targeted rehabilitation.
02
Victorian Drain Surcharging from Extensions
Original narrow-diameter drains serving terraced houses are often overloaded by the additional wastewater from rear kitchen and bathroom extensions. This leads to frequent slow drainage and backups. We quantify flow capacity and compare it to estimated property demand, providing documented evidence for the need for a drain upgrade.
03
Failing Backfall to Main Sewer
The final connection from a property drain to the public sewer on a steep street can develop an adverse backfall if the sewer has settled. This prevents proper drainage and causes standing wastewater. Our engineers use laser-guided CCTV to measure pipe gradients precisely, producing a technical report that proves the backfall defect.
04
Collapsed Yard Gullies
Original brick or concrete yard gullies in Victorian and Edwardian properties frequently crack and collapse, causing surface water to leak into the subsoil and potentially undermine foundations. CCTV inspection of the gully and its connecting pipe documents the failure for comprehensive reconstruction.
Three methods, one visit
High-pressure jetting
Blasts grease, silt and root growth from pipe walls without digging.
CCTV survey
A camera on rods or a crawler unit records the pipe condition end to end.
No-dig relining
A resin liner is cured inside the damaged pipe instead of excavating it.
Drainage in Charlton — FAQs
How quickly can you attend a blocked drain in Charlton?
Same-day appointments are usually available in Charlton and across Greenwich, and next-day almost always. If a drain is actively backing up, say so when you book — active blockages are prioritised.
What does drain clearance cost in Charlton?
A fixed price agreed at booking, before any work starts — see our pricing page for the current service × time-band matrix. Repairs beyond a standard clearance are quoted separately once the cause is confirmed.
Do you know Charlton properties?
Yes — Charlton's housing stock is a blend of Victorian and Edwardian terraces, 1930s semis, and post-war estate housing, often on sloping ground towards the Thames. This topography influences drainage flow and pressure. Many properties have been extended, placing additional load on original drainage layouts not designed for modern bathroom and kitchen volumes.
Can you provide a CCTV report for my insurer or conveyancer?
Every Charlton visit can produce dated CCTV footage and a written defect report, formatted for loss adjusters and conveyancers, typically within 48 hours.
