S4JK Reviews 

Had only ever heard of Japanese Knotweed in articles on Consumer or Gardening programmes. We required a report for a property purchase, Val and her colleagues could not have been more speedy, helpful and understanding. I rarely leave 5 star reviews but S4JK were amazing from start to finish.

My partner and I are currently looking to buy a house and we are first time buyers. When we were recommended to get an invasive species report we contacted S4JK. We had an initial phone call where they explained what they do and answered all of our questions (no matter how silly they sounded). We then had them booked in and had report carried out within 48 hours of initially contacting them. This has allowed us to proceed with our house purchase without increasing any timelines on the purchase.
We were worried at first about approaching a company who deals with invasive species as we thought they may try to recommend some follow on treatment works with ourselves, but throughout the whole process S4JK gave us genuine advice and weren't trying to push a sale on us.

Excellent service friendly and efficient Val and Dean provide a first class service

Very professional, did exactly what they said there were going to do at the time expected.

Very prompt and informative service would highly recommend

very easy to contact and great customer service. got to the Root of my problem!

Friendly, knowledgeable and very helpful.

I spoke to the company a year ago as I have a knotweed problem, they came out quickly to give me a quote and advice. Due to buying the house I ended up hitting a few complications along the way but they have been really good with this and providing everything I would need for the mortgage company.
I would highly recommend

Very helpful people, easy to deal with and by far the most cost effective solution to our knotweed problem.

Going through what is already a stressful time of buying and selling, the last thing you want to find out is that Japanese Knotweed exists in your garden! S4JK put an end to the panic with their advice and brilliant customer service. Val responded quickly to my emails and Dean provided detailed reporting on the same day of site inspection. Treatment started literally a few days later and a 5 year management plan is now in place. Can't fault the services provided by this team and would recommend S4JK to anyone facing this problem.

So friendly, helpful and accommodating.

Nothing is a hassle.

In addition, the treatment is rapidly working. They've assisted the stress of having knotweed by keeping me fully informed.

Very professional, courteous and efficient.Respond swiftly to any queries that I have.

Very good team, very friendly and knew what they were talking about put my mind at rest. Sent the report out within 24 hours cannot fault them.

Excellent service, after a Home Buyers survey claimed I had Japanese Knotweed in my garden, S4JK came to survey the area, no Knotweed found and produced a report the following day. Would recommend the service, very efficient.

A really good experience, long term control plan insurances all from a very friendly run company. Would recommend to anyone.

I work in retail so iv seen some good and bad customer service! This company has the best customer service iv ever seen! I never do reviews but these guys deserve it! Thanks to this company I had my remortgage approved! And the advice given was spot on! They also tried to save me money! I would highly recommend this company!

Thanks again for everything!!!

great so far hopefully 5 when work completed

Great service, Dean was quick to respond to my request to treat the Japanese Knotweed in our garden. They offered a full plan of treatment and guarantees for the work. I'd highly recommend using them.

My experience of S4JK has been nothing but positive. They were super friendly and highly efficient. We've not had any treatment carried out from them as of yet due to knotweed being on the neighbours land rather than our own but Dean was incredibly helpful in advising on the matter. Would highly recommend getting in touch if you have a knotweed problem.
