Boundary Service
Japanese Knotweed Coming From Next Door? Boundary Surveys and Treatment
When knotweed crosses a boundary, the fastest fix is usually evidence plus a joint plan. We survey both sides where access allows, document the spread, and treat it so it stops returning to your garden.
What We Provide
- Independent boundary survey with photos, measurements and spread direction.
- Evidence report you can share with your neighbour, managing agent, insurer or solicitor.
- Joint or one-sided treatment plan, with root barrier options where needed.
- Insurance-backed guarantee for treated areas on your property.
Common Situations
- Shoots appearing under the fence from a private garden.
- Knotweed on council, housing association or railway land next to you.
- A neighbour who will not engage, where you may need evidence for a council or legal route.

Encroachment can amount to private nuisance, and councils can use Community Protection Notices in some cases. Take legal advice for your situation.
The TA6 form asks about knotweed affecting the property. A survey and treatment plan with a guarantee helps buyers and lenders proceed.
