Why London's growth is different
Japanese knotweed was first recorded spreading along the Thames towpaths in the late nineteenth century and London's dense network of rivers, canals and railway cuttings has been redistributing it ever since. Flooding along the Wandle and Lea moves rhizome fragments downstream every winter, while decades of infill on old industrial and railway land means stands are often established metres below modern ground level. A London survey has to account for this history, not just what is visible above ground.
Boundary disputes are common in London
With terraced housing, shared side returns and high land values, knotweed crossing a boundary in London frequently ends up in a solicitor's or party wall surveyor's hands. We provide independent, dated photographic surveys that stand up in correspondence between neighbours, freeholders and managing agents, and we can attend jointly with a party wall surveyor where required.
