Japanese Knotweed Removal Cost
Once it has established itself, eradicating Japanese knotweed is particularly challenging, and unless you hire contractors experienced in Japanese knotweed removal, it can be an arduous task that can take years to complete and expose you to costly repercussions from the various pieces of Japanese knotweed legislation.
How Much Does Japanese Knotweed Removal Cost?
Attempt to remove knotweed yourself at your peril! Rightly or wrongly, Japanese knotweed causes significant blight to property, which can result in huge diminution in property values (typically of 5% to 20%) if removal works are not supported by appropriate guarantees. As such, you are potentially taking a huge gamble if you don’t get the work done by suitably qualified experts.
In order to mitigate such risks you should seek the services of a company specialising in domestic and commercial knotweed removal to ensure full and guaranteed removal and, most importantly, to avoid legal action from future occupiers and potentially affected neighbours.
The cost of Japanese knotweed removal varies depending upon the area of land affected and on the intended use of the land. For the vast majority of cases, a simple herbicide programme will solve the problem. However, if the affected land needs to be excavated in the future (e.g. in order to develop it) then an excavation solution will likely be required. This could include a range of knotweed treatments from full excavation and disposal of the arisings, to partial excavation and use of appropriate root barrier membranes. A rough outline of costs is provided in the table below.
