We measure ourselves using KPIs for each stage of the process and we believe we are the best!

    We understand the need to act fast when sales are threatened by a Japanese Knotweed infestation. We give clear understandable advice to homeowners to allow them to make informed decisions without delay. We are happy liaising between estate agents, buyers and sellers, and will always act with our client’s best interest in mind.

    5 or 10 Year Japanese Knotweed Treatment Programmes with Japanese Knotweed Management Plans and Insurance Backed Guarantees (IBG)

    “What do I get as a customer?”

    Clearsafe Knotweed will provide you with a clear, concise and detailed management plan. This will be a live document that we will update for you each and every year, recording our methods, our Knotweed treatment and our progress with solving the infestation.

    “How will I know when it has gone?”

    Our experts at Clearsafe Knotweed will regularly visit and once the land has been free of Japanese Knotweed growth for at least two years, we will issue you with a “Japanese Knotweed Free“ Certificate confirming that the infestation has been dealt with.

    “What if it comes back?”

    As a company, Clearsafe Knotweed pride ourselves in our ability to tackle any infestation. As a full PCA member we are licenced to arrange 5 or 10 year insurance backed guarantees*.

    (* The ‘Insurance Backed Guarantee’ is a third party product that is required by mortgage companies so that if the contractor becomes insolvent the infestation will still be treated. It lasts for 5 or 10 years after Clearsafe Knotweed has finished the contract. Clearsafe Knotweed has had to become members of the PCA to be able to issue these, we are full members, many in the South Wales area are only provisional members). 

    Clearsafe Knotweed is a registered waste carrier – we can get rid of your Knotweed waste.

      Single Herbicide Treatments

      Some customers prefer to pay for a herbicide treatment programme on a ‘spray by spray’ basis. A single treatment is unlikely to eradicate a Japanese Knotweed infestation, but will knock the infestation back temporarily. 

      Land Clearance

      At Clearsafe Knotweed, we provide specialised land clearance around Japanese Knotweed infestations to help you use the land again without spreading the infestation further.

      Treatment for All Other Invasive Weed Species

      We also deal with other invasive weeds such as Giant Hogweed, Himalayan Balsam, Bamboo and Horsetail (Mare’s Tail).
