Local knowledge
Bow housing, from a drainage engineer's side
Bow has extensive Victorian and Edwardian terraced housing, interspersed with post-war estates and newer canal-side developments. The age of the core housing stock means widespread use of old clay and cast-iron drains. The area also has a network of canals and higher water tables, which can affect underground drainage stability and access.

What fails here
Common drainage problems in Bow
01
Sagging or Bellied Drains
Over decades, ground subsidence, especially in areas near water, can cause sections of old pipe to sag, creating a 'belly' where waste collects and causes recurrent blockages. Fixing this requires either lining or excavating the sunken section. Both methods are on our price list, with lining priced per metre and excavation by the project scale.
02
Cast-Iron Pipe Corrosion
Many older properties in Bow have cast-iron waste pipes, which corrode from the inside out, leading to rough interiors that catch debris and eventually perforate. Replacing these sections is a common job. We charge based on the length of pipe replaced and the labour time, all detailed in our upfront pricing matrix.
03
Canal-Proximity Access Challenges
For properties near the canals, access for drainage machinery can be restricted, sometimes requiring manual excavation or specialised compact equipment. We don't hide these access premiums; if specialised kit is needed, it's listed as a clear item on our quote, based on our standard rates for complex access.
04
Post-War Estate System Obsolescence
Drainage systems on some post-war estates were built with materials and designs now considered obsolete, making parts hard to find and repairs more involved. We are upfront about this: if a non-standard part is required, we source it and charge the clear cost price plus a standard fitting time fee from our list.
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.
