Blocked drain clearance, CCTV surveys and no-dig relining for Colliers Wood homes, from engineers who know Colliers Wood buildings.
Local knowledge
Colliers Wood housing, from a drainage engineer's side
Colliers Wood presents a dense mix of interwar terraces, converted flats, and some mansion blocks, with smaller garden spaces. The high density places significant demand on often-unupgraded drainage infrastructure. Shared drains between converted properties are a frequent headache. The age of the clay systems here, combined with potential neglect in multi-occupancy buildings, means problems can escalate quickly from a slow drain to a complete backup.

What fails here
Common drainage problems in Colliers Wood
01
Blockages in Converted Property Drains
Houses converted into flats often have drainage systems that were not adequately upgraded for increased occupancy. Grease, hair, and debris buildup is accelerated, leading to frequent blockages in shared underground sections.
02
Main Stack Blockages in Flats
In mansion blocks and conversions, a blockage in the main vertical soil stack can cause wastewater to back up into lower-floor bathrooms and kitchens. This is a severe health hazard requiring immediate, 24/7 intervention.
03
Illegal Drain Connections
Unauthorised drainage alterations from DIY renovations or poorly managed conversions can cause immediate blockages or long-term damage to the shared clay system, complicating diagnosis and repair.
04
Sewer Gas Odours from Dry Traps
In little-used ground floor bathrooms or utility rooms in converted properties, water in drain traps can evaporate, allowing foul sewer smells from the clay drain system to enter the home, often mistaken for a blockage.
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.
