Our Japanese Knotweed Services:

Japanese Knotweed Surveys:

We charge £250 + VAT for a specialist Japanese Knotweed Report (residential properties only up to 1 acre). We normally carry out a Japanese Knotweed Survey and have the report back to you within 3 working days. Please call for commercial surveys. Once you have received the report and are happy to proceed with the treatment programme, just give Southwest Knotweed a call.

Japanese Knotweed Mortgage Reports:

If you are buying or selling a property that has Japanese Knotweed within its boundaries or on land adjacent to your property some lenders may require a comprehensive survey (Japanese Knotweed Management Plan) to support any application for a mortgage.

Japanese Knotweed Treatment Plans:

Treatment options depend on certain key factors for example; if there is no immediate construction planned or any urgent pressing need to remove the Japanese Knotweed then it can be controlled with a Herbicide Application Program (HAP). Southwest Knotweed have the experience and knowledge to carry out the following options:

• Japanese Knotweed Herbicide Treatment
• Japanese Knotweed Stockpiling
• Japanese Knotweed Screening
• Japanese Knotweed Rhizome fragmentation and cultivation, including crown removal
• Japanese Knotweed Burial
