removal and treatment
of Japanese knotweed



As part of our commitment to client peace of mind we are able to offer an insurance backed warranty on all sites*, aimed specifically at covering any costs that could be incurred should re-growth occur. Each policy is individually tailored to our client\’s site and the level of cover required.


Where a claim is accepted under the terms of the policy, the cost of treating the Knotweed to eradicate it, will also be included in admissible claims costs.

In the event that the property is sold the policy may only be assigned following an inspection by a “Knotweed Services UK” and payment of a fee. Following a request to carry out a survey, the area identified as the survey boundary then becomes the responsibility of Knotweed Services UK Limited. Any recurrence of Japanese Knotweed within the site boundary will be covered by the warranty document which allows for any eradication works to be carried out at no additional cost to the client.

Warranty includes quarterly inspection during the first twelve months after completion, followed by an annual site visit and report. This level of warranty follows in-depth research by our insurers as to our methods and our results to date.

Discovering Japanese Knotweed on or around your property can be quite distressing. Knotweed Services UK understand that no one wants to be told their property is worth less because of an aggressive weed in their garden however Japanese Knotweed will inevitably devalue your property. Eradicating it yourself would be very difficult and would require lots of time researching the plant properly. It would also require you to purchase expensive equipment, that’s why we strongly suggest using a specialist contractor such as ourselves. We have the professional training and experience to effectively eradicate any Japanese Knotweed infestation.

The PCA works with government departments, provides training and qualifications, establishes industry guidelines and works to improve outcomes across all the sectors it represents for “the damp, waterproofing, wood preservation and invasive weeds industries”.
