The costs of each method vary, and it is important to understand the hidden costs involved so you can make an informed decision about the most suitable solution for your situation.

The extent of the infestation will have a direct impact on the cost of the project, as will the ease of access to the site. If it is difficult to get machinery on to the site, this will add to the overall cost as more time will be needed to complete the work. Local regulations and requirements may also affect costs.

Japanese Knotweed: What’s the Cost to Remove and Why

Excavation and removal is the most effective form of eradication, but it can be very expensive. This is because all waste created during the process is classed as controlled waste and needs to be disposed of at specialist locations far away from the site. In addition, the excavation itself is a very labour-intensive job and requires a high level of expertise to minimize damage caused to adjacent areas.

On-site burial (also known as containment) involves excavating the knotweed-infested soil and burying it on-site within an impermeable barrier. This is a viable alternative to excavation and disposal when these options are not possible due to site restrictions or environmental concerns.
