    Highly recommend. I enquired with Clear safe in the evening and James went down the morning the next day to survey the property. He then produced an extensive survey report for us free of charge. Couldn’t have been more helpful!

    I've just conducted a knotweed/ invasive plant survey from James at Claresafe. I'm so impressed with the level of service, knowledge, skill and care of these guys. James was fantastic, he even went to the neighbouring properties to ensure there were no invasive plants there as well. Just above and beyond my expectations. Delighted with the service. Highly recommend for total piece of mind when buying a property. Plus, i couldn't believe the price! Amazing value for money????. 10 out of 10 service all round. Thanks so much James

    Highly recommend these guys. Following on from my initial call to CLEARSAFE KNOTWEED, James arrived at the arranged time. We walked the garden and he identified the plants and the knotweed. I felt relaxed in his company as even though very professional, his friendly demeanor made this company easy to talk to. The report was written up and a management plan put in place within a few days as promised. Massive thanks to you for taking the knotweed stress away from selling my house!

    I can’t speak highly enough about the service we were given by Clearsafe. At short notice and working to our deadline, James explained how the system worked and patiently worked through my questions and concerns. We felt confident to go ahead with them. Within a week I had a detailed management plan and an insurance-backed, long term guarantee in my possession. I think that we made the best possible choice of contractor and would recommend Clearsafe without hesitation.

    James went above and beyond supporting us in getting our mortgage accepted to proceed on a property, which had a significant amount of Knotweed on the neighbouring land. He worked with us and the builder to ensure we could proceed in the purchase. Also provided us with peace of mind. A true expert!

    From the off, James was incredibly helpful and open with communication, making the process run extremely smoothly. The team communicated excellently with neighbours to explain the process and any possible restrictions. It was not only my property that benefited from James and the teams expertise. Would highly recommend.
