Residential Japanese Knotweed Eradication

Whether you’re buying a property with Japanese Knotweed and trying to get a mortgage or selling a property with Japanese Knotweed we’ve got you covered.

Japanese Knotweed is harder to get rid of than you may think, but with our vast knowledge of the plant and cost effective management plans we can help and support you every step of the way!

As PCA experts, we know the ins and outs of Japanese Knotweed relating to residential properties and are fully qualified to write Japanese Knotweed reports that will satisfy the needs of most lenders. We can also offer Insurance Backed Guarantees (IBGs) that most lenders will ask for if a Japanese Knotweed management plan will not suffice alone.

Our Japanese Knotweed management plans are covered by a 10 year PCA approved guarantee that starts after our 5 year treatment plan is completed. These plans are also transferable into the new homeowner's name at no extra cost!

S4JK will visit your site and conduct a full initial assessment, checking boundaries and adjacent properties where possible. A site assessment is essential whether it’s for a private property, brownfield, commercial or industrial site to determine the extent of the infestation.

The assessment will include:

  • a full walk over the entire site
  • a site plan and photographs indicating where the invasive weed is situated
  • inspection of the neighbouring properties/land to identify problem areas
  • recommendations for current maintenance schedules
  • history of past treatments and how development plans might affect the treatment
  • risk assessment


Once the site assessment has been carried out, a management plan will be produced, containing:

  • an evaluation of the infestation and the objectives of management
  • recommended control options
  • control actions and the risks associated with those actions
  • advice on how to prevent Japanese knotweed spreading on site
  • a treatment schedule
  • a full breakdown of the treatments available and associated costs
