Japanese knotweed growing through a house.

Tuesday 25th October 2011

p>Japanese knotweed can grow through a house, this is rare and is usually caused by a number of factors, one of which may be that the building concerned was constructed over an existing stand of Japanese knotweed, without proper precautions being taken. The article on the attached link with the Daily Mail may be such an instance or may possibly be caused by other factors.


It is a financial disaster for the couple concerned and our sympathies of course are with them. Sadly, neither buildings insurance, nor the NHBC guarantee, may cover Japanese knotweed growing through a building – read the small print in your policy! Usually it is a case of Caveat Emptor – let the buyer beware. The only possible way to cover yourselves is to ask the question (or get your solicitor to do so) “Has there been any Japanese knotweed on this site/property/neighbouring property to your knowledge in the last 20 years?” If the answer is ‘Yes’ than seek further information.
