Drainage Services Balham
Blocked drain clearance, CCTV surveys and no-dig relining for Balham homes, from engineers who know Balham buildings.
Local knowledge
Balham housing, from a drainage engineer's side
Balham's housing mix includes solid Victorian terraces, inter-war semi-detached homes, and numerous converted flats in larger houses. The area is known for its clay soil and tree-lined streets. A key feature is the prevalence of basements and lower ground floor conversions, which sit below the level of the main sewer. This often necessitates the use of pumping systems or macerators, adding mechanical complexity to the drainage setup and creating new potential points of failure.
Engineer's note
From a failed basement pump to tracing a cross-connection in a conversion, our service-time pricing model means you pay for the engineering fix, not just a temporary clearance.

What fails here
Common drainage problems in Balham
01
Basement Pump Failures
Many lower ground floor flats and basements rely on pumps or macerator units to lift wastewater up to the main sewer level. These units are prone to jamming from debris, motor burnout, or switch failures, leading to immediate and total drainage failure for the affected unit.
02
Inter-War Pipe Joint Degradation
The drainage systems in the area's 1930s semi-detached homes often used different materials and jointing techniques. These older joints, particularly in cast iron or early concrete pipes, are now degrading, leading to leaks that undermine foundations and cause localised saturation.
03
Clay Soil Shrink-Swell
Balham's clay soil expands when wet and contracts when dry. This seasonal movement can displace and misalign drainage pipes over time, creating low spots where waste collects and causes recurrent blockages, especially in long runs to the rear of properties.
04
Conversion Stack Cross-Connection
In houses converted to multiple flats, poorly executed plumbing can lead to cross-connections between separate waste stacks or incorrect venting. This causes airlock issues, slow drainage across multiple units, and smells that are difficult to trace.
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.
