S4JK Reviews 

Great communication, they turn up when they say they will. Very polite as well and keep you informed with what is happening. Very helpful guys. Highly recommended

5 star service. Cannot recommend enough. Friendly. Polite and courteous. Happy to provide extra advice.
Results are the best I’ve seen in years.
Much appreciated. Keep up the good work.
Pity the council won’t contract you guys as they clearly can’t do it themselves.

Incredible service. From the very first phone call to the assessment. Everything explained. On my second stage of treatment and can already see very positive results. Very friendly and accommodating. Definitely recommend.

Provided treatment for two stands of knotweed on either side of a small stream. Due to the proximity of the watercourse, stem injection was used - very effective on the stems treated, but it takes a few rounds before stems in the centre of a large growth area are reachable! A range of treatment plans are offered, including options that satisfy conveyancing requirements.

They turned up as planned.
As nothing was done we must await until september when, hopefully, some positive action takes place.

Really helpful and knowledgeable. Great customer service. Treated the problem and continue with follow ups

Quick and transparent service, would highly recommend!

Prompt advice and excellent knowledge. They quickly helped identify a potential invasive weed and advised accordingly. A pleasure to deal with. Would highly recommend.

Helpful and supportive throughout a process relating to the development on which I live. Thorough and professional.
Clear information regarding work carried out and future plans.

Honest, professional advice. Spent time discussing the issue offered reassurance and didn't push any treatments that weren't necessary. Definitely happy to recommend. Thankyou!

Great professional service.
I would highly recommend S4JK for any Japanese knotweed concerns

Contacted them regarding suspected Japanese Knotweed in my garden.
They explained their service and treatments clearly, with an initial indictation of cost.
They then scrutinised more photos I sent them, and immediately called back saying I did not actually have Knotweed.
So, very clear and honest.

Dean was very helpful and knowledgable about the species we had growing in our garden. I would fully recommend speaking the them if you have any worries.

We've just raised a query about possible japanese knotweed in our garden.
We sent over some images and received a response within minutes. These guys are super helpful and I wouldnt hesitate to recommend them to others!

Gave me free advice after I shared a picture of a weed in my garden. It wasn’t knotweed thankfully

We were told by a surveyor we had Japanese Knotweed in our garden on a house sale, called S4JK and spoke to a lady called Val.
Val was very informative and knowledgeable about Knotweed and offered a garden inspection with a written report.
Within Two days Val and Dean had arrived, on time and carried out a full walkaround the garden, took photo's and measurements, both were friendly, polite and very professional and within a couple of hours we had the full report on company headed paper sent over via e-mail.
A very prompt professional service I would recommend to anybody and definitely would use again.

After finding a plant that looked very much like Japanese Knotweed in the garden of our newly bought home we were obviously very concerned. We called up S4JK and were greeted by very friendly and sympathetic staff who arranged to come by that same afternoon to investigate for us.
To our relief, they identified that it wasn't Japanese knotweed.
We're so grateful for their quick response, we called at 8:30am and had a result by 1:30pm. I'm not sure we could have coped with the tension for much longer.

We were in the process of selling a property in the U.K. We are based in France. A potential issue was raised by the surveyor regarding some bamboo in the garden. I contacted S4JK who dealt with it immediately. There communication is excellent, they are professional and friendly. I can highly recommend their service. They managed to turn a stressful situation into an easily resolved one.
