Japanese knotweed

The Knotweed Experts are one of the UK’s leading contractors in the knotweed identification, control, treatment and removal of Japanese knotweed. Our success is built upon our experience, expertise, service delivery and customer care. Coupled with being mortgage compliant, Property Care Association (PCA) approved and up to 10 years guarantee on our treatments, finding a solution to knotweed treatment has never been so easy.

We understand that finding out that your property sale or purchase is affected by Japanese Knotweed can be a daunting time and hearing horror stories of house prices plummeting up to 40% around the UK (25% in London) and properties having to be rebuilt because of the spread of knotweed, can make dealing with the problem extremely stressful and time consuming.

Mortgage lenders can refuse to lend against properties with knotweed due to damage of foundations, drainage systems and walls and this can prove to be a difficult situation, especially if you are in a house buying chain.

By following our simple online enquiry system, you are just a few clicks away from resolving your knotweed problems and having full assurance that your problem has been resolved quickly and effectively. Act now and book your survey – we promise to deliver your survey results report within 2 working days of the survey taking place.


By choosing The Knotweed Experts, resolving your knotweed issues is just a few simple steps away.

Step #1

Book your survey

What is included in our Knotweed Survey Reports?

  • A site visit carried out by one of our Knotweed specialists where they will inspect your property, gardens front and rear along with any neighbouring properties where possible.
  • Whilst on site we accurately measure and record the Japanese knotweed infestations and provide a scaled drawing of your property and infestations.
  • Define your JKW risk number as specified in the RICS information paper. This is required for your mortgage company.
  • Provide you with a full mortgage approved written report that includes a detailed quote, information pack and Knotweed management plan.
  • Everything you need in a quick and easy format to satisfy your mortgage company/ buyer/ seller.

We appreciate that a fast turnaround time is essential for property owners and purchasers. We acknowledge that you need to act now, therefore we will get your comprehensive report sent out to you along with your quotation within 2 working days of our site visit, (subject to season and location).
