Japanese Knotweed Specialist
Knotweed is not a job for a general gardener or a landscaper with a knapsack sprayer. It needs correct species identification, a rhizome-depth survey, certificated herbicide application or engineered excavation, and documentation a mortgage lender will accept. That is all we do.
What makes us specialists
Qualified, insured operatives
City & Guilds NPTC PA1/PA6 certificated spray operatives, working to PCA-aligned standards, with £10 million public liability cover on every job.
Specialist identification
Japanese, giant, Bohemian and dwarf knotweed all behave differently — and half the plants we are sent photographs of turn out to be bindweed, dogwood or Russian vine. We confirm the species before anyone quotes you.
Lender-accepted documentation
PCA-compliant management plans and a transferable 10-year insurance-backed guarantee — the paperwork UK mortgage lenders require to release funds.
48-hour attendance
Same-day species confirmation from photographs, surveyor on site within 48 hours across England, Wales, Scotland and Northern Ireland.
