We're a dedicated team of professionals who share a great deal of experience. We invest heavily in the continual training of all our employees, ensuring you always have a highly qualified team working on your project with the latest industry accreditations.

Our founder Mike Clough comes from a surveying and landscape architecture background and has run both construction and grounds maintenance companies in the past. Hence, he was well placed to observe the increasing problem of Japanese Knotweed, setting up the company in response to a growing number of enquiries.

Over the years, our experience and expertise has grown to such an extent that we are now a trusted contractor for clients such as the Environment Agency and British Waterways as well as major construction and development companies across the country.


"Japanese Knotweed presents an increasingly serious threat to landowners and the construction industry. Our aim is to offer the most effective and cost efficient solution to this problem and to remain as the UK's leading solutions provider"
