So our team at Knotweed Services (UK) Ltd completely understand and recognise the anxiety and stress many homeowners feel when confronted with the prospect of having Japanese Knotweed on their property.

Perhaps you are looking to purchase your dream home, only to find it has Japanese Knotweed in the garden? Should you run a mile??

Perhaps you are looking to remortgage your current home and Japanese Knotweed is having an impact?

Given the negative press Japanese Knotweed has in today’s media, it is no wonder that individuals are often left feeling traumatized, with nowhere to turn.

The press reports often refer to the problems people face securing mortgages and are often coupled with reports about the potential damage that Japanese Knotweed can do, both structurally and to the value of properties but they never offer any reassurances or solutions to property owners.

Buying or selling your home? Does the property have a Japanese Knotweed infestation? Read our guide to find out what your next move should be.


Knotweed Services (UK) Ltd offer a range of successful Japanese knotweed treatment methods:


Crown and stems are capable of regenerating and even small fragments of cut crown or stem are capable of regenerating and becoming a new plant – removing these from the equation is a great strategy.

New plants will grow from the nodes of pieces of green stem, in soil or water. Mechanical cutters, will spread knotweed in this fashion. If stems are dried until they are dark brown, they will not regrow unless the crown (base of the stem) is still attached.

Crown removal is exactly what you would expect from the title. By removing the cranes of the Japanese knotweed plant, we remove the majority of biomass that is underground. With the crowns removed – our herbicide and stem injection treatments are much more effective.


Biomass is a form of excavation and removal but instead of extracting all of the soil impacted by Japanese Knotweed, we only remove the infested parts of the soil.

It is an effective, productive and maintainable Japanese knotweed control method that allows the reuse of the previously infested soil. Reducing the use of landfill.

This method is most effective when used in conjunction with other control methods. For a domestic property, a small digger will scrape back small layers of soil at a time and one of our surveyors will remove any rhizome as they’re unearthed.


Resolving your Japanese knotweed problem with Knotweed Services is an uncomplicated process.


You can upload your pictures to us using the methods above. If you are 100% sure it is JKW and this has been identified on a homebuyers Survey, a Valuation Survey or even a gardener, please progress to step 2.


A PCA Qualified Surveyor will conduct the site survey. Pictures and measurements will be recorded and a visual inspection of the property boundaries (where possible neighbouring property) will be inspected. All factors/variables affecting the JKW will be recorded. Such as:

  • The size of the infestation
  • The location
  • Nearby watercourses
  • Does the property back onto Network Rail land?
  • Access issues
  • Distance to habital space (Please see RICS assessment framework for further guidance on distances) and
  • JKW encroachment from/onto neighbouring property.

In cases of encroachment, where possible, our expert surveyors will identify where encroachment has taken place. At this stage, any future plans for the property (IE. landscaping/potential extension/renovation works) will also be discussed.


If you are in the process of buying or selling a house, the report produced by our qualified and experienced surveyors will be required by the mortgage lenders- even if the suspected plant is NOT JKW.

The detailed report will conclude the findings of the site survey and the recommendations for the best method of control/treatment. This is known as a management plan and at this initial stage, we refer to it as a proposal.

The management plan proposal will outline the best method of control/treatment specific to each individual property based on the findings of the site survey. Our bespoke Management Plans include Herbicide treatment in the forms of Stem Injection, Knapsac Sparaying, Foliar Wiping & Crown Removal; as standard.

The Management Plans are for a duration of 5 years and include a 10 year Warranty. (Insuranced Backed Guarantees are available upon request). Finally, a quotation for the bespoke management plan will be prepared and sent to you, along with the management plan proposal. (We aim to complete paperwork within 7 days (Max)).


If instructed following the quotation, Knotweed Services (UK) Ltd will commence a 5 year treatment plan to control the Japanese Knotweed and a 10 year warranty is issued.

A typical contract includes:

  • 2/3 year Herbicide/stem injection treatment plan * (We aim to conduct 2 treatments per year)**
  • Crown removal
  • 2/3 years of monitoring the site for any regrowth
  • A final inspection
  • A full management plan
  • A 10 year warranty

*As we are dealing with nature, we constantly assess the effectiveness of treatment. Every JKW infestation, in different environments, reacts differently. Knotweed Services will treat for either 2 or 3 years, whichever is necessary until successful.**Dependent on how effective previous treatments are, this could be more or less.

Knotweed Services (UK) Ltd are employed to take full responsibility of the Japanese Knotweed infestation,making buying & selling property easier as we provide all the documentation mortgage lenders/purchasers/estate agents and solicitors require.

As we are a PCA approved contractor, this treatment plan is fully compliant with industry standards and will be recognised by banks and building society's to allow lending against a property. Therefore, once payment is received, the paperwork is issued immediately, which can be sent directly to all parties. Hence, this process should not hold up the buying or selling process.
