Japanese Knotweed Excavation and Removal Services
Japanese knotweed excavation is widely regarded as one of the safest and most effective methods of removal. At Japanese Knotweed Agency, we manage the entire process from initial survey through to excavation, licensed waste disposal, and full documentation. All works are carried out in line with industry best practice and Japanese Knotweed Agency standards which is supported by a 10-year guarantee, meeting the requirements of legal professionals and mortgage lenders.
Complete physical removal, guaranteed results
Where immediate, guaranteed eradication is required, excavation and removal offers the most decisive solution. Unlike treatment programmes that work over multiple growing seasons, excavation physically removes the Japanese Knotweed and its extensive rhizome network from your land in a matter of days — leaving the site clear and ready for immediate use.
Our experienced excavation teams use mechanical diggers and screening equipment to identify, isolate and remove all contaminated material in full compliance with the Environmental Protection Act 1990. Every project is backed by a guarantee, providing reassurance to property owners, buyers, developers and mortgage lenders.
