Buying house with Knotweed in adjacent woodland

Taj121

Thank you for all the advice, I'm still in two minds but its reassuring there's a 10 year warranty in place so any regrowth will be treated. Of course worry is present it may spread into our garden but there's 6 small isolated patches present in the woods of which most has already been treated so hopefully it will be completely eradicated by next year. How effective are root barriers?

Are there any small watercourses around? These can help spread the weed. Check is there is any water like a small stream or similar running through the woodland and how close it passes to the property.

If there is a warranty in place, it shouldn't be an issue unless you have a seriously flightly lender. It's also a good sign that the neighbouring property owners are taking it seriously - what you don't want is to buy next to a place with JK where the owner is uncontactable or doesn't care.

There is a small watercourse present on the other side of the woods about 20 acres away from the property so fortunately nothing close by.

JKW doesn't have to be a deal breaker. At this time of year it's difficult to tell if you have knotweed on your property. I have a small amount of knotweed at the bottom of my garden coming from neighbouring land. I've just been given a £5k quote to have a root barrier put in and a 4 year course of treatment which is guaranteed for 10 years. My advice is get a reputable company (e.g. IWM) to check for knotweed, suggest and quote for any treatment and then deduct the cost from any offer you make.

I got rid of some at the bottom of the garden by spraying it twice a year for several years. It kept coming back at first but it eventually gave up and never came back - that was 20 years ago. At my present house we have got ground elder which IMO is worse than JKW.
