Japanese knotweed?

lon_85

Hi guys

Recently had an offer on a flat accepted and going through the paperwork- it has come to light through the searches that the property previously had japanese knotweed in 2015 and has since been eradicated- certificate provided shows that it has been removed and warranty states until 2026 - does this mean it can return? Do i need to do continuing treatment which seems to be expensive- should I be worried?

Thanks

There is always the possibility that JK might return for up to 10 years or so after treatment, but it's a relatively low risk and you are covered up to that time, provided the guarantee is transferable and insurance backed against the company going bust.


Rather obviously, you cannot 'treat' something that isn't there, but if fronds of the stuff did appear, you'd be wise to leave them alone, use the guarantee and let the company deal with them.


JK is not the terrible monster it is made out to be by the likes of the sensationalist mainstream media. Lenders get spooked by it, which is why there is so much public interest, but it's been around for over 100 years and you'd be hard-pressed to find a well-maintained property it's affected in a severe way. Certainly, modern foundations are well up to coping with it, but the situation need never arise, now we have effective chemical controls.


Get your solicitor to check out the guarantee before you explore the garden!

Thanks Davessnave - I have the warranty and its up till 2026 so I guess it should be ok until this time but after this period may need to be topped up. Will look into it further before making a decision.

I wouldn't worry. The insurance is an expensive piece of paper paid for by a mug a few years ago.

If you ever find it again you can get rid of it easily enough and its only cowboys who charge silly money.
