Evidence of where the knotweed is and where it is coming from, for a neighbour or landowner.
Free photo ID check · Mon–Sat 8am–6pm
Knotweed spreading from next door, from a rented property or from council or railway land is one of the most common reasons people contact us. A survey records where the stand is, where it crosses the boundary and how it is likely to spread. That evidence is what you need to raise it with the owner, and a root barrier can protect your side while it is resolved.
