Japanese Knotweed Removal Costs

The cost of removing Japanese Knotweed generally depends on the size of the area to be treated and the method of removal.

Where Japanese Knotweed management plans for mortgages and eradication programs will vary from property to property, in our experience the cost of Japanese Knotweed removal is unlikely to exceed £2,000. The total cost would include a site survey, management report, treatment program, monitoring and a 10 year insurance backed guarantee. A first course of action is taking advantage of Landtech (UK) Limited's FREE Japanese Knotweed Identification Service.

Japanese Knotweed Removal Methods

In most cases, a herbicide treatment is the easiest solution and cheapest cost, but must be recognised as only a method of "control” due to the risk of dormancy and regrowth.  The three treatments available are Foliar Spray Application, Stem Injection and Stem Filling.

Complete Japanese Knotweed removal requires excavation. Stockpile On-site is not as immediate as Burial On-site, and while Removal To Landfill is also an immediate solution, it is by far the most expensive. With all three methods, the total removal cost will depend on the size of the area to be excavated.

Japanese Knotweed Removal Surveys

Before considering Japanese Knotweed removal, we would need to conduct a site survey. Landtech (UK) Limited provide both residential Knotweed surveys, and full site commercial surveys. Residential surveys are ideal for home sellers, buyers and mortgage lenders of Knotweed affected properties and commercial Japanese Knotweed surveys will establish on-site problems and any risks for proposed development plans.
