The best way to prevent Japanese Knotweed from devaluing your property, is to recognise and treat the Japanese Knotweed as early as possible. In order, to treat the weed you will need to invest in expert help. As only a qualified Japanese Knotweed expert can use the translocating herbicide. This is because it is significantly stronger than anything available to the public. 

There are several treatment options available, please see our ‘Treatment Services’ page for further details. In the above case, the client paid upfront for the plan to be implemented as it was a three-year process. As a result of this, it meant that we could issue a 10-year guarantee and the sale of the property with Japanese knotweed in Hertfordshire could go through successfully.

At the 18 month mark the Japanese knotweed had responded well to the treatments. This was in the summer of 2017. The following year there was little or no growth. However, we continued to monitor the site until there had been a full two years of no growth. With the 10-year insurance backed guarantee the new owners are confident that there will be no problems in the future.
