Japanese Knotweed Management

Japanese knotweed (Fallopia japonica) is a highly invasive non-native species which if left untreated its growth can cause damage to buildings and/or hard surfaces, potentially resulting in extensive costs to property owners.

We are a member and approved contractor of the Property Care Association, a member of the Yorkshire Invasive Species Forum, and the framework contractor for invasive species for the Environment Agency.

If you have knotweed on your property we can offer:
  • A detailed site inspection and survey of your property
  • Detailed advice on management options
  • Herbicide treatment by highly experienced operatives
  • Onsite burial
  • Mechanical screening
  • Excavation and disposal
  • A full knotweed management plan
  • Our Insurance-Backed Guarantee



Our Japanese knotweed specialist is accredited by the PCA as a Certified Surveyor of Japanese Knotweed, and all our operatives hold NPTC qualifications in the safe use and application of herbicide.
