What our clients say
Suzi was so helpful taking the time to advise me on Japanese Knotweed risks.
I used Environet following a recommendation to help with invasive Japanese Knotweed in my garden. Mathew Day was the main person I dealt with and he was excellent. Very professional, responsive and managed to co-ordinate with other contractors working on my property to remove the knotweed. I would definitely use them again because their knowledge and experience is second-to-none.
Excellent service, great communication and very prompt delivery of all documentation. The Team were really really helpful and professional. I would highly recommend.
