    Japanese Knotweed Identification & Removal

    What is Japanese Knotweed?

    If you are not sure if the invasive weed infestation on your property is actually Japanese knotweed, have a look at our detailed knotweed identification guide that will help you be the judge.

    Japanese Knotweed (Fallopia japonica) and its hybrids are a non-native, invasive species of plant. Since it was introduced into the UK as an ornamental garden plant in the mid-nineteenth century, it has spread across the UK, particularly along watercourses, transport routes and infested waste areas and of course private gardens.

    Japanese Knotweed Mortgage Problems

    The majority of UK major lenders will refuse to lend against a property if their surveyor identifies Japanese knotweed at a property you are purchasing, selling or even re-mortgaging, especially if it is located within seven metres of a habitable space. This is due to the aggressive nature of the plant and potential damage it can cause to the building, consequently severely affecting the value of the property. As a minimum, the mortgage lender will request a ‘Japanese Knotweed Management Plan’.

    Price Match Policy

    We are extremely confident our services offer value for money and are at the more ‘cost effective’ end of the industry, however should you obtain a formal lower quotation, we will better it by 5%. As simple as that.

    Chris inspected a property that we are purchasing for Japanese Knotweed. He was able to view the property at short notice and quick to follow up with us afterwards. Luckily no knotweed was found! We were very happy with the service.
