Japanese Knotweed Doesn't have to be a Dealbreaker

Hear how Simon Harper bought a house near Reading that was infested with Japanese knotweed.

Just a Few of the Good Words our Clients Have to Say about Us:


"Excellent service from Environet, they covered every aspect of the works with diligence and professionalism and went the extra mile when needed."

Tim Lewis, Design Coordinator  - Kier Living South West


"Thank you to Paul and Anthony for their excellent work here. They were an absolute pleasure to meet. Their knowledge and professionalism in all they did was superb."

Rachel, Home Owner - Bexhill-on-Sea


"Everyone found your presentation to be a helpful and informative. Your enthusiasm for the subject also encouraged everyone to get involved and ask questions, benefiting everyone in the room. If we have any questions in the future regarding the identification or management of Japanese Knotweed we will be sure to contact you and the Environet Team."

"We would definitely recommend you to anyone we know with a Japanese knotweed problem."

Malcom Fairclough, Home Owner - South East


"I am delighted to report contracts were exchanged today so a very happy seller and a very happy buyer!

THANK YOU so much for actioning the report so professionally and so quickly – we will, without hesitation recommend you in the future."

Richard Prynne, Home Owner - South Central


"I wanted to write to say how impressed I have been with Environet from start to (I hope) finish.  From first discussing options with the Sales team, who demonstrated a good knowledge of various options and considerations, to liaising with the Operations team and watching the works being completed by Environet. The whole team have all been a credit to the company.

I did approach other companies who were keen to push me down the herbicidal route and offered very little in the way of any broader advice, however from start to finish it has been clear that Environet does employ experts who can offer sound advice on all options available.

My colleagues and I do often get asked by clients (developers, contractors, local authorities, housing associations and landlords) to bring in experts to undertake knotweed remediation and I would have no hesitation in putting Environet forward to external clients and colleagues within the practice as a primary point of contact."

Jonathan Harris, Home Owner - South East


"Your service has been very friendly, professional and efficient.

I was very pleased with each step of the process and have no complaints whatsoever ."

Robert Anstice, Home Owner - Somerset


"The service received throughout, from first phone contact, to the end of the job, was incredibly supportive and helpful. 

When dealing with a stressful situation of knotweed and house selling, your company did everything possible to facilitate this and make it all happen. 

Enormous thanks."

Sally Davenport, Home Owner - South London


"I’d like to also just convey how impressed we’ve all been with the service and work of your team – we’d have no hesitation in using you again (even though I hope the situation never arises… !), nor in recommending you to anyone else."

Anonymous, Developer - Devon


"We are pleased with the service you have provided and the team on site were very polite and friendly. 

You are very fortunate to have a great team at Environet.  All colleagues I dealt with inspire great confidence that Japanese knotweed is not the disaster it may appear to be at first sight and were happy to answer lots of undoubtedly daft questions in conversation or email. 

I hope we don't have another site with Japanese knotweed but if we do then I will certainly be back to you."

Anonymous, Home Owner – Somerset


"After contacting several companies about Japanese knotweed removal, and having my time well and truly wasted, I finally spoke to, in my opinion, the best company in the UK, Environet.

Dealing with them is like a breath of fresh air, they are reassuring, professional, and offer great value for money."

Anonymous, Home Owner - North Devon


"Environet responded to our initial enquiry in an exemplary fashion, by attending site within the timescale provided along with providing us a clear and concise remediation strategy in line with our build programme, ensuring no delays on site which, as developers, is key. 

All personnel we dealt with where professional and courteous, and fully liaised and conformed with the PC and the specific site requirements and provided all relevant information in a timely manner. 

We will be using Environet as our first port of call for all future invasive specie issues moving forward and would have no issues in recommending them in the future."

Ethan Ballam, Technical Manager - Devine Homes PLC


"Having been informed by our estate agent that our purchaser's survey had discovered Japanese knotweed (of which we were unaware) on our property I immediately contacted Environet. Within 48 hours they were on site. A couple of days later we received a detailed eradication plan and the first treatment took place about a week later.

I was extremely impressed by Environet’s efficiency and courtesy and am pleased to say the property has now been sold.

I would happily recommend Environet to anybody with a similar problem."

Tim Obey, Home Owner - Bristol


"Having researched Japanese knotweed online and read the many scare stories, I was relieved to come across the services of Environet UK Ltd.

From my initial contact, through to treatment, I have received prompt, efficient and knowledgeable service. After an initial site visit, a Management Plan was put in place and certainly the knowledge and information I received has now confirmed to me that Japanese knotweed is nothing more than a treatable nuisance!

As my house was on the market my potential buyers had been advised of its presence by the estate agent. Having spoken to Environet directly, they were not deterred as a treatment programme was in place, supported by a Lloyd’s insurance backed guarantee and now the house has been sold.

Thank you Environet UK Ltd."

Anonymous, Home Owner - South Devon


"I was concerned when I found the knotweed since I had only heard the scare stories and was worried I may not be able to do my extension. The whole thing was very irritating. But I would say to others, ‘Don’t panic but make sure you research the solution for your needs’. 

Having done quite a bit of research online, I contacted Environet and met with them at my property. Through their expertise and understanding of my requirements we went for the full and immediate eradication programme called Resi-Dig-Out™. They were quick to visit and survey my property and then the works only took a matter of days causing minimal disruption.  

I would also recommend to anyone that you get a cast-iron guarantee for the works underwritten by a rated insurer like Lloyd's, and certainly not just by the company doing the works, since you will need this both if the problem reoccurs and for future property sale."

Paul Ryb, Home Owner - North London


"Excellent technical advice and reliable service throughout the project. All calls were returned promptly to answer my queries and the process was fully explained to me ."

Trish Maffin, DandM Maintenance & Services Ltd - North Wales


"I just wanted to say thank you for your service. From the initial enquiry, every question was answered promptly, providing us with all the information we needed to go forward. Each time we spoke on the phone I was reassured with your knowledge about Japanese knotweed ."

Anonymous, Buyer - South East England


"I just wanted to thank your company Environet for your help and intervention in helping me sell my home. It has been a pleasure dealing with such a professional and dedicated team. My buyers, as you know, were having trouble securing a mortgage because of the 'dreaded' Japanese knotweed on the council’s property that was coming into my garden. You took the time to explain thoroughly the process to me.

Without your intervention I doubt this sale would have happened. You took time out to personally contact my buyers, the brokers and the estate agents, keeping me informed at all times regarding progress.

I would have no hesitation in recommending your company and wish you every success in the future."

Louise Martin, Home Owner - North London


"We found ourselves having to sell an elderly relative's property in order to fund specialist nursing care. When the Estate Agent valued the property at over 50% less than we had expected due to the presence of Knotweed we were absolutely devastated. We were contacted by every "knotweed expert" under the sun with promises, but it was Environet who seemed to have the track record, expertise and insurance backed guarantees to give me the confidence I needed. They also offered me payment terms that meant that I didn't have to pay anything until the property had been sold.

Every communication with Environet from day one demonstrated their wealth of knowledge, they were always professional and efficient but also had a genuine empathy to our plight.   As soon as the initial treatment had taken place we were in a position to market the property and have since successfully sold and realised the full value.  Thank you Environet, without your excellent expertise this would have surely been a very different outcome for us."

Liz Wakeman, Home Owner - South Wales


"We had a reservation on one of our developments where the customer was extremely nervous about historic Japanese knotweed. With help from Environet, including their treatment and a 5 year insurance backed guarantee, we were able to secure knotweed indemnity insurance from Countrywide Legal Indemnities. It was this policy, which covers the knotweed liabilities such as cost of any further treatment, repairs to damage caused by knotweed, and legal expenses cover, that finally satisfied the buyer, his solicitor and lender that they should proceed with the purchase. Thank you to Environet and CLI for making it happen."

Donna Cole, Field Sales Manager - Persimmon Homes PLC


"May I take this opportunity to thank you for the promptness and efficiency of your service generally. When I first contacted you last year, I was impressed with the speed with which you were able to respond to my requirements, and since then I have always found your company to be focused on responding to me as a customer in a timely, flexible and supportive manner, even in subsequent dealings after the transaction had taken place.

Thank you for helping me to resolve my knotweed problem in a way which set out to be supportive and reassuring, and which delivered exactly what I needed in a timely manner”.

Dr Kay Turner, Home Owner - Southwark, London


"I was really happy with the service Environet provided, from my initial enquiry to the completion of the extraction of the Knotweed.  It is obvious the company has a lot of experience and expertise on the subject.  They understood my situation, were courteous, friendly, reassuring and efficient, carrying out the work in a very short space of time. On completion the area was restored (minus the weed) and very clean and tidy.  I would definitely recommend the Environet team to anyone who comes up against this problem.""

Jan Parsons, Home Owner - Essex


"Environet's Japanese knotweed eradication has proved to be highly effective on our development sites. Thank you for your excellent service, fast response and professional consultancy support."

Nigel Tompsett, Commercial Director - Berkeley Group PLC


"We asked Environet to eradicate some Japanese knotweed found in the garden of our new home in Wimbledon in 2005. They undertook the work very professionally to the promised timescale and the knotweed has not yet returned. We wanted a quick solution but did not want to dig up our entire garden, so when we heard of Environet's in situ chemical treatment, we thought we had the answer - and time has proved us right."

Andrew Croker, Home Owner - SW London


"Environet provide a very cost competitive alternative to other forms of remediation and carried out the removal of knotweed in a very efficient and effective manner."

Michael Bryant, Development Manager - Eagle One Ltd  


"Environet gave me full advice on the most economical and environmentally friendly methods of treating knotweed. Soon after August 2006 we set up an order with Environet to eradicate Japanese Knotweed on my site at Uddingston Grammar in Glasgow. Environet have been very helpful, courteous, efficient and very pleasant to work with."

Ghassan Hemsi, Project Manager - Morgan Sindall  


"We at Salya homes have used the services of Environet for Japanese knotweed eradication at our development site at Chelmsford . They are very knowledgeable and professional. On the whole we were very satisfied with their services and would highly recommend them."

Munaf Patel, Project Manager - Salya Homes 


"Environet gave us great advice on our 8 acre site at Godre Graig Swansea. They eradicated the Japanese Knotweed in the most professional and helpful manner, listening and solving our problems along the way. We cannot thank them enough."

David Hall, Director - Zoemack Ltd   


"Having been let down by another party, we urgently needed assistance with a large-scale knotweed infestation. To add to the problem, the infested site also had an extremely high environmental sensitivity which complicated the treatment options. Environet rose to the occasion and efficiently and professionally dealt with the problem and ultimately provided us with a 5 year guarantee of the knotweed eradication."
