Drainage Services Welling
Blocked drain clearance, CCTV surveys and no-dig relining for Welling homes, from engineers who know Welling buildings.
Local knowledge
Welling housing, from a drainage engineer's side
Welling is dominated by interwar semis and 1950s/60s housing, typically with modest but well-planted rear gardens. The housing density means drainage systems are often compact and interconnected. The prevalence of original clay pipes here, combined with popular garden shrubs and trees planted decades ago, leads to frequent, localised blockages at property junctions and bends.

What fails here
Common drainage problems in Welling
01
Shared Drain Choke Points
In many Welling streets, several properties share a drain before connecting to the sewer. A collapse or root block at this shared junction can affect multiple homes simultaneously, creating an urgent, multi-property emergency that needs immediate coordination.
02
Kitchen Drain Grease & Root Combos
Older clay kitchen drain runs are narrow and rough. When grease buildup combines with fine root hairs from nearby shrubs, it creates a solid, concrete-like blockage very close to the house, causing rapid sink backup.
03
Collapsed Section Under Side Extensions
Many homes have later side-return or rear extensions built over the original drainage path. Ground disturbance and weight can fracture the old clay pipe beneath, leading to mysterious dampness or odours inside the new room.
04
Failing Air Admittance Valves
Modernised bathrooms in older homes often use these valves. When the underlying drain is partially blocked, negative pressure can cause valves to fail, resulting in gurgling sounds and slow drainage throughout the upstairs fixtures.
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.
