Customer Reviews


Amazing, thorough service! Would definitely recommend if you have this on your property. Thank you!

Brilliant Service! Chris was very knowledgeable and went above and beyond with his service.
Fantastic results after just one spray! Really happy with this company, would highly recommend them, great results and a very reasonable price for the treatment.

Chris inspected a property that we are purchasing for Japanese Knotweed. He was able to view the property at short notice and quick to follow up with us afterwards. Luckily no knotweed was found! We were very happy with the service.
