Japanese knotweed surveys for property sales and purchases
If suspected Japanese knotweed is affecting a sale, purchase or mortgage, start with a reliable identification and a clear account of the site.
How we can help
From suspicion to a documented plan.
Identify and survey
Send photographs for an initial view. A site survey can then record visible growth, its location and the circumstances that matter to your property.
Plan and treat
Where knotweed is confirmed, we can set out a management plan and a proposed herbicide treatment programme with follow-up monitoring. We tailor management plans and supporting documents to meet the lender’s stated requirements where applicable. Insurance backed guarantees may be available for agreed 5 or 10 year plans.
Share the right documents
Tell us what your buyer, solicitor, surveyor or lender has asked for. Requirements vary by transaction; agree the documents and guarantee terms with them before commissioning work.
Common starting points

I own an affected property
Understand the extent of the growth and discuss a managed treatment programme.
Discuss treatment →Before you book
What about booking and deposits?
Deposits are required before booking. We confirm the scope, deposit and applicable terms before you commit.
An inspection is required before quoting for a ten-year plan, barrier membranes or excavation. Photos help us prepare but do not replace that inspection.
Next step
Tell us about your site.
Share the location, photographs and any deadline. We will discuss what a useful first assessment looks like.
