    Treating your property in Merthyr Tydfil 

    Japanese knotweed infestations come in all shapes and sizes and it’s safe to say that after 15 years we have pretty much seen it all.

    But each knotweed problem is different and we pride ourselves in always finding a bespoke solution to your individual problem.

    We asked our lead surveyor James for his recollections of his last treatment in Merthyr.

    “In early summer, I was called out to survey an infestation in a potential building plot joined to a pub.

    The infestation was very strong, covered all of the plot and was encroaching into the pub garden and the domestic gardens to the rear and on the other side.

    The knotweed has already been treated by the owner’s friend (way too early in the season which doesn’t help) but I could see it was a sub-standard treatment because the knotweed was only damaged and has recovered.

    There are building materials stored all over the land which are preventing some growth but I advise them not to move them until the knotweed has been treated this year.

    I also advised the owner to approach the neighbours to get permission to treat the land next door.

    We visited again in the autumn and treat the knotweed in the plot and the neighbouring gardens. The treatment will be less effective due to the premature treatment by the owner’s friend but is still worth doing.

    When we returned to survey the following spring, some of the building materials had been removed, so we contacted the owner to see if we could get some more moved before the knotweed grows too much more which would prevent them removing any more materials without damaging the knotweed.

    We returned again in the autumn and applied a treatment to the infestation which is only slightly weaker than in the previous year.

    This time, when we return the next year in early summer, the infestation has retreated back from the boundaries 1-2m, the growth is only 40% as dense as previously and the individual canes are much shorter than at the same time in year 1.

    The story is the same when we come back in the autumn to treat it again, plants at around 30 to 40% of the expected size and density….can’t wait to see it next year!”

    Highly recommend these guys. Following on from my initial call to CLEARSAFE KNOTWEED, James arrived at the arranged time. We walked the garden and he identified the plants and the knotweed. I felt relaxed in his company as even though very professional, his friendly demeanor made this company easy to talk to. The report was written up and a management plan put in place within a few days as promised. Massive thanks to you for taking the knotweed stress away from selling my house!

    I can’t speak highly enough about the service we were given by Clearsafe. At short notice and working to our deadline, James explained how the system worked and patiently worked through my questions and concerns. We felt confident to go ahead with them. Within a week I had a detailed management plan and an insurance-backed, long term guarantee in my possession. I think that we made the best possible choice of contractor and would recommend Clearsafe without hesitation.

    James went above and beyond supporting us in getting our mortgage accepted to proceed on a property, which had a significant amount of Knotweed on the neighbouring land. He worked with us and the builder to ensure we could proceed in the purchase. Also provided us with peace of mind. A true expert!

    From the off, James was incredibly helpful and open with communication, making the process run extremely smoothly. The team communicated excellently with neighbours to explain the process and any possible restrictions. It was not only my property that benefited from James and the teams expertise. Would highly recommend.
