Is Japanese knotweed a reason to pull out?

    The RICS are definitely saying that the problem is exaggerated. But they also say:

    It is acknowledged that currently the presence of Japanese knotweed may be a significant impediment to the sale and purchase of a property, and it can affect both value and saleability.

    If the public perception of JKW means that affected properties have a lower value, the valuer cannot ignore that, even if he and the RICS think the public may have got it wrong. 

    As thing’s currently stand, it may well not be necessary to pay full price for an affected property.


    Hi

    Best post on the thread.

    In my judgement, if anything has a negative impact on any property/ land, any reasonable person will accept that it may affect the saleability.

    Another example and just for heads up and this  can be compared with this JK. Subsidence that has been repaired, and underpinned. This as most people would accept means the problem has been sorted on the whole. However, a lot of people will not buy them, therefore resale value/saleability is affected.

    Therefore, anyone citing it does not affect the value and the saleability, in my judgment lacks the insight of property market trends.

    Linnk is a good read, IMHO for any serious buyer/s

    Utter, utter, rubbish shown to be wrong by the RICS document which even talks about the media perpetuating myths.   This is the very worst example of that.  How on God's earth does a plant get into roofs??!  It's like the Day of the Triffids according to this article.   
    I once viewed a quite optimistically priced property with a tree growing on the roof, and more than a few with quite lush lawns growing in their guttering. I'm guessing animal transfer or a strong wind and distinct lack of property maintenance? 

    Either way, not something endemic to knotweed.

    Yes, I should have been clearer that I was still talking about knotweed.  

    The Birmingham magistrate courts are developing a veritable arboretum on their walls.  Shocking lack of maintenance, it's a travesty.

    I'm familiar with RICS' position on japanese knotweed and the updated guidance around it, it doesn't change the fact that japanese knotweed easily penetrates concrete and masonry and can easily destroy foundations. aside from such catastrophic outcomes, it's also close to impossible to eradicate it, making it a persistent problem when structural damage is not necessarily an issue.

    "It’s capable of doing immense damage by weaving its way into walls, roofs, and foundations, before expanding. At this point, it can cause cracks and force its way into buildings."

    No one has said that people don't have differing degrees of knowledge and therefore attitude, just like most of things that come up in survey.  

    Contrary to what you say, the article is  NOT a good read for serious buyers, it's a shoddily written article by someone that's never bought a house, gets paid to produce content regardless of quality, done no research and couldn't care less because they're getting paid for the clicks provided by their scaremongering by Checkatrade who have clearly sponsored it.  
    nonsense, you're just talking rubbish. JK literally destroys concrete, a tiny crack is all it needs. this is not even up for debate, it's a fact. a simple google search will provide plenty of documentation for it.
    Have you read the document linked to on the first page that I've been talking about the entire time? 

    Didn't think so.

    You haven't read it. 

    "Practical experience after 2012 increasingly questioned a widely held assumption that Japanese knotweed posed a structural risk to building foundations. During 2016, practicing RICS surveyors and specialist contractors contributed data from surveys towards research on the typical impact of Japanese knotweed. The research paper................published in 2018, reported that Japanese knotweed poses less of a risk of damage to substantial buildings than many trees or
    woody shrubs."

    "Like most plants, Japanese knotweed will follow the line of least resistance as it develops, preferring to go around obstacles rather than through them. As it seeks light and water, it may grow through pre-existing cracks in brickwork or concrete but its presence does not necessarily mean it has caused the cracking. The Fennell et al paper categorically dispels one oft-quoted Japanese knotweed myth by explaining that it is ‘impossible for it to grow through intact concrete’"

    "Research has demonstrated, and it is now generally accepted, that Japanese knotweed
    poses little or no risk of structural damage to robust buildings with substantial foundations such as dwellings"

    Read that and did find it of interest, never heard or thought of JK being edible but there is not a chef in the land that could convince me to try it.

    your points are... academic, just like the paper you quote. yes, in theory, a solid concrete block won't be penetrated by a JK root. in practice, especially on older properties, concrete is not always 100%. foundations crack, bricks crack, mortar cracks.
