    James from Clearsafe surveyed our clump forming Black Bamboo and recommended how to remove it effectively from our border. James then attended on an agreed date and removed the Bamboo. The only way you would know any work was completed in the garden is the Bamboo is not there. James is very professional and we would highly recommend him. Thank you James for your help, it is very much appreciated.

    Responded to my email query within 24 hours. James called to my property and explained clearly what needed to be done. Totally professional and helpful without wanting to charge me for work that didn't need doing. Excellent.

    Excellent service, highly recommend. I had a letter from a neighbour concerned there was a canopy of knotweed on our border coming from my side. I contacted Clearsafe after work looking to book an assessment and James kindly said he’d pop over that evening! James quickly confirmed it was not knotweed, was likely a fruiting vine and sure enough found some small fruits. He kindly went with my neighbour to assess the border from their side also and confirmed there was no knotweed. He explained the differences in the stem and leaves and what to look for. Incredible service, professional and friendly. It was incredibly stressful thinking there was knotweed but James was very kind, knowledgeable and reassuring. Highly recommend.

    We are in the middle of purchasing a property and it was brought up in the survey that JKW was likely to be present. We contacted several JKW specialists in the area. Clearsafe went above and beyond. In a matter of hours they had identified the plant and offered invaluable information, advice and support to help us progress with our sale as well as providing us with excellent quotations. I will not be hesitating to use or recommend this company in the future.

    We’re in the process of putting our house on the market and concerns were raised as to whether some weeds in the garden were knotweed. Contacted James who requested photos. He came back to me within an hour in between other jobs and was able to not only confirm it wasn’t knotweed but tell me exactly what the weeds were. Really appreciated his friendly but professional approach and quick responses. Would highly recommend.

    Had a bamboo patch in the garden out of control. Phoned up, sent a video of the area and within weeks it’s all been sorted. Credit to the lads, they were on time and put a shift in even when the sun was on full beam. Will definitely be recommending you to friends and family. Thanks again

      Commercial Japanese Knotweed Removal, Excavation, Onsite Solutions, Soil Minimisation and Disposal

       

      • Japanese Knotweed Excavation – We specialise in digging out just enough soil to remove all of the Knotweed root or ‘rhizome’ material, whilst keeping the quantity to deal with onsite as low as possible to minimise the costs.
      • Rhizome Removal / Soil Sifting to Restore Soils –Where there is space onsite for temporary storage or time before building starts, we can process and remove the root or ‘rhizome’ material in combination with herbicide treatments to make the soil usable again.
      • Creating a Japanese Knotweed Cell – We can bury root or ‘rhizome’ materials contained in a purpose designed membrane to create a Japanese Knotweed cell. The cell construction ensures that new growth cannot reach the surface and all materials eventually become unviable.
      • Dispose of Soils to Landfill – Landfill is the most expensive solution but sometimes it can’t be avoided. After minimising the amount of soil produced, we will ensure that your soil is categorised at the least expensive disposal rate whilst complying with waste laws and arrange transportation and disposal to a licensed landfill site.

      5 or 10 year Treatment Plans, Land Clearance, Other Invasive Weeds and Insurance Backed Guarantees

      Sometimes after a project has been built, 5 or 10 year Japanese Knotweed treatment programmes can be put in place to give peace of mind to buyers and tenants, especially where infested soil has been kept onsite to be processed, treated and used again..

      Single Herbicide Applications

      Some customers prefer to work on a ‘pay by spray’ basis. Whilst a single treatment is unlikely to eradicate a Japanese Knotweed infestation, it will knock the infestation back somewhat and can show a contractor has fulfilled their responsibility whilst in control of a site.

      Land Clearance

      At Clearsafe Knotweed, we provide specialised land clearance, including tree works around Japanese Knotweed infestations to ensure that the infestation is not spread leading to increased costs and legal liability.

      Treatment for all Other Invasive Weed Species

      Whilst we deal with a majority of Knotweed, we are increasingly dealing with other invasive weeds such as Giant Hogweed, Himalayan Balsam, Bamboo, Horsetail (Mare’s Tail) and many others; please give us a call to discuss any invasive weed issues.

      *The Insurance Backed Guarantee (IBG) is a third-party product required by mortgage companies so that if the contractor becomes insolvent the infestation will still be treated. We can issue IBGs through our full membership of the Property Care Association (PCA).*
