Complete eradication of Japanese knotweed and other invasive weeds


“After speaking to several other [companies] I’ve decided to go with your knotweed plan. You were the most reassuring and your phone call did the most to put my mind at ease. Thanks again for what was the most realistic and least panic-inducing conversation I have had on this subject.”
SNL, Shropshire

“Thank you for being so helpful and professional - I am really glad I chose your company. [All parties involved] are keeping your details on file for future reference because you have been so good.”
AC, Essex

“We've been very pleased with the service and prompt response, and particularly appreciated the practical advice on selling our property.”
SM, London

“Faced with the apparent threat of Japanese Knotweed scuppering the sale of my property, I called The Knotweed Company. Within 2 hours they had carried out a full survey [that] showed a shrub in the garden had been mis-identified both by a building surveyor and by a landscaping company. Their service has been fantastic and my sale is proceeding only thanks to their intervention.”
AV, Hampshire

“Thank you for the advice you have given me over the telephone. I am very appreciative of the time you spent talking to me about knotweed and if I come across anyone [else] with this problem I will definitely be recommending your company.”
LR, New Forest
