Thank you

Thank you, your expert team managed to understand from a photo that my garden had no knotweed present according to the photos. A Surveyor who went there and was present seems that didnt know much about Knotweet hence why he said and requested to be checked by a specialist as to his decision was that might look like Knotweet. Pitty that people like the one visited my property delay the process in selling my property because of his poor knowledge in understanding what knotweet is!

Free identification service - excellent!

I found some worrying looking plants in our garden that AI kept saying was Japanese knotweed. I found this website online and decided to send some photos to real human experts using their free identification service. They replied in under 1 hour confirming that it's not Japanese knotweed, which was a huge relief. Excellent service and so pleased that I found it.

Bamboo treatment

We have some bamboo in the garden which had not spread for years, it started to move, on contacting the company we were helped in a short space of time. This treatment is ongoing, today we missed the gentleman carrying out the treatment but on contacting the company a revisit a few hours later was arranged. The explanation of what had been done and advice on what was happening with the bamboo was given so patiently and clearly that it was really helpful. thanks to Sharon for sorting the revisit and David for help and advice. This company have always been really helpful, but this was super!!

Is it Japanese Knotweed or not?

My gardener told me that he had spotted Japanese Knotweed in my garden, and I was devastated, and panic stricken! After all, he was the expert not me! Then I found your website and the offer of a free evaluation and I jumped at the chance. I sent you a photo of the ‘suspect’ plant, and within 3 minutes you replied, telling me that it was NOT Japanese knotweed! I was so relieved and so happy!

I would have been willing to have paid up to £50 for your expert opinion, but you gave it to me for nothing! I will definitely recommend you to my friends in the future! :)

Free identification service well worth it

I was concerned that we had Japanese Knotweed growing in our garden and managed to find JKL's website after a quick Google.

I dropped them a short email with some photos attached and within the hour they had responded to reassure me that whatever was growing wasn't any variant of Knotweed! I can highly recommend their free identification service.
