As proud members of the Property Care Association’s (PCA) ‘Invasive Weed Control Group’ (IWG) which ensures you receive the industry’s leading solutions to a high standard all from an audited contractor, it also ensures we can offer robust and meaningful Japanese Knotweed guarantees that you can rely on in the event that you have Japanese Knotweed to ensure you are covered if it ever returns.

Our guarantees can be issued to any type of site whether is a residential home or a construction site to be turned into a housing development.   Our Guarantees also act as a solution to funding and house/land sale issues. In black and white, this is the best and only guarantee you can get when it comes to Japanese Knotweed!

So why is it the best?

Our gurantee’s are independently written and approved not along by the Invasive Weed Group of the Property Care Association (PCA), but also recognised by the Royal Instituation of Chartered Surveyors (RICS).

We can offer both 5 & 10 year guarantees with all our Japanese Knotweed treatments and they offer ‘complete peace of mind’ from the day our treatment is carried out.  

Insurance backed guarantees

As PCA approved contractors we can also offer Insurance Backed Guarantees to give you that extra peace of mind. These insurance policies are offered by GPI (Guaranteed Protection Insurance Ltd) for a one off additional cost.


GPI are a general insurer authorised and regulated by the Financial Services Authority and insurance backing means that in the unlikely event that we were unable to continue as a business, your Japanese Knotweed guarantee policy would continue to be effective and covered by Another PCA contractor approved by GPI. This policy of insurance can also be passed to future home-owners (at a fee) and a JKW survey will need to be undertaken if not carried out at the start of the treatment plan.

Why is a Japanese knotweed guarantee so important?

Due to the way Japanese Knotweed grows, spreads and survives, Japanese Knotweed is a very difficult plant to eradicate and can cause significant damage if not treated correctly.

Therefore our guarantee ensures that if our Japanese knotweed treatment and removal processes have not worked, then under your Japanese Knotweed guarantee, you are covered for up to 5 or 10 years from the completion of our treatment plan. You will need to contact us as soon as you have seen any re-growth (as stated in the guarantee) so that we can arrange for a surveyor to survey your property (subject to our terms of our guarantee). Please ensure you keep hold of all your original paperwork.

We can offer guarantees for both residential and commercial sites including new builds.
