The cost of removing Japanese knotweed can vary, this article explains why and what’s involved.

Here are some key aspects of services geared for removing Japanese knotweed:

  1. Identification and Survey: A professional CSJK surveyor will assess and record the extent of knotweed infestation on your property, accurately identifying the plant to evaluate its impact, and recommend appropriate measures.
  2. Treatment Plans: Services provide tailored treatment plans based on the severity of the infestation. Common methods include herbicide application, excavation, or a combination of both.
  3. Herbicide Treatment: Trained and qualified technicians apply specialised herbicides to control knotweed growth. This method requires multiple treatments often over several years. A Knotweed Management Plan and guarantee can be provided to assist with property purchasers requiring a mortgage, as this provides evidence of knotweed being controlled.
  4. Excavation and Removal: For severe cases and when knotweed needs to be completely removed, excavation is used. It involves digging out the knotweed rhizomes (underground stems) and disposing of them properly (to a licensed landfill). This method requires the knotweed contractor to hold a special waste carriers license.
  5. On-Site Burial: In certain circumstances, and on certain sites (depending on its planned use) knotweed can be excavated and buried on-site, provided certain conditions are met. This prevents the spread of rhizomes and future knotweed growth.
  6. Root Barriers: When knotweed is excavated, installing root barriers prevents knotweed from spreading into neighboring areas. This must be carried out by specialists in knotweed control to be effective.
