At last minute mini-digger delivery was a problem due to overhead wires.
This did not faze the workforce at all. Extra hands were provided.
Any options or issues were discussed before proceeding on that section of the job.
Great clean-up job especially as it was in poor weather.
Nice guys as well to have around the house.
We had an area of bamboo travelling under the garden wall from next door.
As next door were not cooperative we decided to bite the bullet and have an area of the patio dug-up, roots removed and a root barrier installed.
Environet we fast and efficient in turning up to inspect, write a report and a quotation.
They were also good in the execution as I think the patio lifting was harder than anticipated.
Good workmen and company.
We’ll see in a few years if any growth comes back. Next time its an insurance claim and legal impact on next door neighbour.
We had a large clump of bamboo that was encroaching into a neighbour’s garden. Nathan, the member of staff assigned to our job was professional and friendly. He did a survey which led to a thorough written report and quotation. The removal work took four days, entailed removing a part of our fence and was undertaken very thoroughly. The team laid mats over our lawn to protect the lawn from the digger’s tracks. The site was left very tidy with all debris removed. Overall, I felt the price charged was fair given the extent of the work needed and it was competitive compared to the other quote I obtained.
I used Environet for guidance and support after I found knotweed in a recently purchased property. They were swift, polite and very helpful. They performed partial dig out and installed a weed barrier around the affected area.
I had small regrowth which I reported and swiftly a member of the team would come out and remove any root and growth.
I would highly recommend this company and if I ever needed similar work in the future this is who I would use. Just moved out of the property affected and transferring the guarantee was so quick and easy. Matthew day especially was always supportive throughout the whole process and nothing was ever too much effort.
Many thanks to him and his team
Very well organised team of people who got on with the job very efficiently. The equipment arrived in time for the team to use. A large area of bamboo was removed in a week. Fortunately the weather was on their side. The area was left tidy and great care was taken of the established garden around it.
From first contact with Richard, the survey from Mat and the actual removal work done by Gavin I always felt reassured that I was dealing with a reputable company of experts.
I bought a house and had no idea that there was bamboo in the garden and even if I had, I initially had no idea that bamboo was invasive. It all came as a very nasty surprise!
While the problem was not that extensive I wanted it dealt with. Gavin did an incredible job in cold February weather and was so easy to deal with. He kept me updated on everything that was going on and left the garden very tidy.

Frequently Asked Questions
Keen to learn more? Check out the most common questions our team receives here:
How do I get started?
What if I’m not sure it’s knotweed?
You’re not alone. Most clients aren’t sure — that’s why we offer free, expert photo ID with a same-day response. Better safe than sorry when it comes to your property value.
Can knotweed really affect my mortgage or property sale?
Yes. Many lenders will decline a mortgage if knotweed is found and not under a professional, insured management plan. Buyers often walk away. That’s why fast identification and action are critical.
Is it illegal to ignore knotweed?
It’s not illegal to have knotweed on your land, but you can be fined or sued if it spreads to neighbouring properties. You also can’t dispose of it like normal garden waste — it’s classified as controlled waste.
How much does treatment cost?
It depends on the size and location, but we offer multiple options — from one-off excavation to multi-year plans — with clear pricing and insurance-backed guarantees. You’ll never be in the dark.
What if it comes back after treatment?
We offer long-term warranties and an AA-rated insurance policy that covers regrowth. With Environet, your property is protected now — and in the future.
