Why do clients choose Japanese Knotweed Plus?

  • Our surveyors hold certificates of Surveyor in Japanese Knotweed issued by the Property Care Association (PCA). All our services and related paperwork are accepted by mortgage lenders and banks.
  • We are the only company that will send two surveyors to carry out the survey, further ensuring nothing is missed. This will eliminate the possibility of any future legal action against you.​
  • Not using third parties or subcontractors allows us to deliver a profession service to you starting with the initial survey, treatment, and issuing our completion certificate.
  • With our many years of experience of dealing with Japanese knotweed all our clients have been able to sell their properties without any problems.

If you have a problem with invasive weeds on your property, we can help.

Japanese Knotweed Plus is a company which specialises in the professional removal, eradication and control of Japanese Knotweed in the North West of England. A hugely aggressive invasive species, this perennial weed can cause cosmetic and severe structural damage to buildings, reduce the value of your home and make selling it very difficult.

The law in England and Wales stipulates that there is no legal obligation for landowners to remove Japanese knotweed. However, if you do intend to sell and there is evidence that the plant is on or near your property, you will almost certainly need to undertake a survey in order for prospective buyers to be able to be granted a mortgage. With our worry free service, we will provide you with the documents required to satisfy your buyer’s mortgage lender, which will include a comprehensive survey report and bespoke Japanese knotweed management plan.

Once the Japanese knotweed is properly controlled, you will be able to sell your house without any hiccups. What’s more, we offer 10-year Insurance Backed Guarantees for all of our work, ensuring that the treatment will run its full course.

Here at JK+, we have nurtured great relationships with hundreds of estate agents in Greater Manchester, Cheshire and Lancashire, helping to identify thousands of knotweed and giant hogweed outbreaks. We provide this identification service for free to domestic customers, too; just email a photo of the suspicious plants to us via our Contact page.


If you suspect you have Japanese knotweed, we will identify the plant free of charge. Just take a photo of the suspicious weeds and send it to us via email or the Contact Form on our Contact Us page.

Low Cost

We will inspect your site as soon possible when you book a survey. A professional survey report will usually be with you the very next day. The survey will be free if you decide to undertake a treatment plan with us.

Free Insurance
Backed Guarantee

Your treatment plan will be covered by a free (subject to T&Cs) 10-year insurance backed guarantee, provided by a specialist insurance company.

Our Testimonials

Just wanted to say how impressed I was with the level of service provided, including your knowledge, your advice, your professional manner, your quick response to all enquires.

I would highly recommend your company to friends and family.

Mary, Worsley, Greater Manchester

I would like to thank Stephen and Igor for their prompt reply to my question. I had been told that I had Japanese Knotweed in my garden and rang them in quite a state! I was told to email them a photo of the offending plant and almost immediately I received a reply saying that in fact, it was not J K.

I am so grateful to them for putting my mind at rest so quickly. A brilliant service.

Jane, Bingley, West Yorkshire

We would highly recommend Stephen and Japanese Knotweed Plus Ltd to anyone struggling with this invasive weed. We found them to be very knowledgeable and put us at ease providing all the information we need. They were reliable, always on time and kept us informed by phone and e-mailed a copy of the treatment plan including updates after each visit so we knew how well the treatment is going.

Chris, Oldham, Greater Manchester

I cannot thank them enough for their speed, professionalism and support taking care of something which could have been so distressing to us.

Not only have they completely satisfied ours and our buyers’ needs, they also ensured that we had a 10-year guarantee for the continued treatment of the works to ensure that everyone was comfortable with the future.

Emma & Marco, Moston, Greater Manchester

I inherited a house, the estate agent said it would be easy to sell. First buyers loved it had it surveyed and found Japanese Knotweed. That was the start of my nightmare. They couldn’t get a mortgage. Two more buyers and still the same, no bank or building society would entertain it. I was given the phone number of Japanese Knotweed Plus Ltd. They came to see the property and explained everything to me. Reassured me as I was beginning to think I would never sell the house.

They came up with a management plan and as a result, I have finally sold the house. They have been brilliant, really nice guys, never pushy I would definitely recommend this company to everyone. Japanese Knotweed is an awful thing to have people don’t realise how bad it is. I am so glad this company came to my rescue.

Janet, Atherton, Greater Manchester

Thank you so much, Stephen, you are a true gent! I will be recommending your company on local forums for weeks to come! Thanks again.

Julie, Ashton-under-Lyne, Greater Manchester

Thank you so much for your expert knowledge, your ability to provide clear and understandable guidance and continued help and assistance whilst ascertaining the identity of my garden plant. I am extremely grateful for your patience and your time whilst helping me with this.

The conversation you had with the man from the council has confirmed the true identity of my plant to be Angelica and the council are in the process of writing to me to confirm this. The man from the council also commented on how understanding, patient and knowledgeable you were.

I would highly recommend your company and service.

Liz, Stretford, Greater Manchester
