Treatment and/or Removal Options

When prospective customers ask about Japanese knotweed removal, there isn't just one treatment option. It depends on why you're treating it (buying or selling a home are common factors). There are a variety of methods we can utilise, but the options below simplify the most common Japanese knotweed treatments.

Herbicide Treatment

This option controls knotweed growth and is ideal for:

  • Homeowners
  • Buyers
  • Sellers
You will receive a comprehensive Knotweed Management Plan (KMP) with a herbicide treatment and guarantee schedule. If you're selling your home, the KMP can be transferred to the new homeowners.

This treatment option is accepted by most UK mortgage lenders and gives you a 10 year Insurance Backed Guarantee.

Excavation

Excavation is recommended where long-term herbicide treatment is not desirable, or if the affected area is to be disturbed, e.g.:

  • Turfing
  • Paving
  • Driveway
  • House extension
  • Outbuilding (garden shed, garage, greenhouse)
You will receive a guarantee of up to 10 years with optional Insurance and this method is accepted by most mortgage lenders.
