For commercial land developers, current homeowners, and those with pending mortgage applications, Japanese knotweed discovery can cause worry, headaches, and unexpected costs if not approached correctly.  

Especially pressing for commercial developments where time and resources are finite and sensitive, project timescales can quickly come under costly jeopardy with a Japanese knotweed infestation. Conservation of the natural environment is also critical in ensuring projects don’t disturb natural habitats. Everything considered, complete and efficient knotweed eradication and removal is the only guaranteed way to ensure a problem like this doesn’t return.  

From identification and surveying lands for red flags of a knotweed infestation to establishing an effective management plan, Japanese Knotweed Specialists’ team of professionals can help you remove this invasive weed once and for all.

Our Japanese Knotweed Removal Services

Appearances can be deceiving and, whilst Japanese knotweed is an attractive plant, the Environmental Agency (EA) has identified it as stubbornly aggressive and invasive. That means, where it has been identified by the UK government as “controlled waste”, there are regulations when it comes to the identification, prevention, removal and disposal of the plant.

That’s why hiring an expert with insurance-backed guarantees is one of the only ways to ensure thorough, long-lasting and complete eradication of Japanese knotweed that won’t pose problems in the future.

Here at Japanese Knotweed Specialists, our removal services are designed to offer not only thorough eradication of any knotweed problem, but peace of mind that once it’s gone, it doesn’t return. Our Japanese knotweed removal services include:

    • Removal on sites from 1m2 to over 1000m2
    • Both commercial and residential  removal performed by accredited experts
    • Surveys, both dog and human detection, to understand the extent of the problem
    • Sifting and screening for rhizomes
    • Cost effective herbicide treatments
    • Off-site removal with accredited waste licences
    • Insurance-backed guarantees between five and 35 years

    Our Japanese Knotweed Removal Process

    Explore different areas of our Japanese knotweed removal services for both residential and commercial properties:

    1) It All Starts with Japanese Knotweed Identification

    The first step to handling a suspected Japanese knotweed infestation is to have it professionally identified (you can get an initial idea by looking at our knotweed gallery). Alternatively, you can email clear photos of the suspected plant to info@jkws.co.uk for further advice.  

    You may find it difficult to identify Japanese knotweed depending on the time of year, as appearance is seasonal and changes quite significantly. Typically, the first shoots of knotweed start to appear above ground as early as March, before aggressively growing up to 2cm every day. In the winter, whilst it looks dormant, the root system – known as the rhizome – can still be actively spreading underground.  

    The most common characteristics of Japanese knotweed include:  

    • heart shaped leaves  
    • creamy white flowers that appear late summer  
    • aggressive, zig-zag growth habits.

    Once Japanese knotweed has been identified, you will need a survey to understand the scale of the problem.

    2) Then We Survey the Land  

    After the successful identification of Japanese knotweed, treatment options and the scope of an infestation can’t be fully understood until our professionals have been to your site.  

    Every Japanese knotweed survey undertaken will determine the most effective removal method on a case-by-case basis. Our recommended treatment plans and approach will be tailored to your home or land development project.  

    Our team of specialists will survey the full site to determine how to approach the problem. We do this to minimise removal costs, determine the risks of every project, and establish the environmental impact of treatments.  

    During site visits, our PCA Accredited Surveyors will inspect your land and any surrounding areas for signs of knotweed (including overgrowth). In certain circumstances, this might carried out by sniffer dogs.  

    If you know you have a knotweed problem, book a survey with us today.

    3) Receive Your Bespoke Management Plans

    After completing the survey, you can expect to receive a detailed report and Knotweed Management Plan (KMP) within 5 working days (depending on the complexity and size of your project).

    As Japanese knotweed is considered a form of contamination (other examples include Asbestos), the Environmental Agency considers planning remedial methods a critical step in controlling infestations. Our KMPs comply with “The Knotweed Code of Practice”, which means that our plans safely deal with knotweed encounters.  

    What’s Inside?  

    In your bespoke report, you can find the following information:  

    • a map to indicate the extent of an infestation  
    • an understanding of where it interferes with neighbouring land  
    • a Management Plan with removal costs  
    • a project timeline.

    4) Knotweed Removal Options  

    Depending on the area our professionals will be working with, the different environmental considerations, and the unique project parameters (such as timescales), we can advise on the best approach.  

    Our specialists can remove knotweed in one of many ways and some approaches may even involve multiple methods:

    5) Guarantee Issued

    Once a plan has been issued, approved, and paid for, then your treatment is guaranteed. Our work is PCA-approved and fulfils mortgage lender requirements, which is because our professionals can issue RICS- (the Royal Institute of Chartered Surveyors) approved surveys.  

    Depending on the project, our guarantees can last up to 35 years and act as legal evidence that the infestation is being treated.  

    Optional GPI insurance policies can offer additional peace of mind

    6) Japanese Knotweed Removal Aftercare

    Once our team have treated and removed Japanese knotweed, we won’t leave you to deal with any future occurrences or issues that arise. We offer a holistic removal service, where we work with you to monitor the site post-treatment.

    Everything you Need to Know About Japanese Knotweed Removal  

    Why is It Important to Remove Japanese Knotweed?  

    Japanese knotweed can regrow with only a thumbnail’s worth (around 0.2g) of rhizome (the root system) left. Therefore, while a herbicide treatment can be effective in certain scenarios, in order to guarantee, removal is the only way to completely eradicate it.

    Japanese Knotweed Specialists offers a variety of removal services, included blended approaches, for instance applying a herbicide treatment and excavating.

    What Are the Long-Term Dangers of Japanese Knotweed?

    While there are no impacts to human health, the damage to buildings, gardens and neighbouring land is vast, thanks to Japanese knotweed’s ability to spread up to 10cm a day in growing season. This invasive species will grow through concrete, tarmac and even building foundations.

    It's also illegal to let knotweed knowingly spread, and you could be fined or land a jail sentence in severe cases
