We’ve been successfully removing it for 23 years. Our expert team can resolve your knotweed problem – so don’t believe all the scare stories you’ve read in the press.

All of our work comes with a 10-year insurance backed guarantee, underwritten at Lloyd's. This means you can trust us to do the job well - and nearly all banks and building societies will trust our guarantee as a security for making you the mortgage offer you need.

We can help you right now if you need a specialist solution to knotweed.

Our experienced team can arrange a survey that will clearly highlight the required work to treat or remove the knotweed, and the costs involved.

You will be armed with the full facts to sell your house and for buyers to understand how to proceed.

Most UK lenders immediately accept our insurance-backed plans to allow the house sale to continue.

Which means you are ready to move forward at the first available opportunity.

And we are ready to remove your knotweed efficiently and effectively.



  The service received throughout, from first phone contact, to the end of the job, was incredibly supportive and helpful. When dealing with a stressful situation of knotweed and house selling, your company did everything possible to facilitate this and make it all happen. Enormous thanks.
