Removal of Japanese Knotweed

Japanese knotweed is a nightmare for someone who is looking to sell their property. This is because of two reasons. The first one is that a house having knotweed will be devalued and hence it is a potential loss to you.  Secondly, it becomes mandatory to get the Japanese knotweed removed from your house if you want to sell it. That is a really expensive process and it takes time.

The estate agents are bound by law to keep every detail about the property open and exposed. Therefore it is illegal to hide a Japanese knotweed infestation.

Here are the five things that Estate agents should know about Japanese Knotweed

  1. Japanese knotweed is a seasonal plant. It becomes dormant in winter and is active in summers. The winter appearance of this plant will make it look like a normal plant that can’t cause any damage. But, it has really long roots and it grows at a fast pace which has multiple issues associated to it. The property surveyor will find out the remains of plant if it’s the winter season and hence it cannot be hidden.

2. The pace at which knotweed grows can cause a lot of damage to the surroundings. It includes the foundations of the house and the drainage system. If any of these is damaged, the house becomes an inhabitable place and all of your money spent on the property will go in vain. The presence of knotweed on a smaller scale is a smaller problem because either the owner can get at work to start removing the knotweed, which would take a lot of time, or they can get help of a professional and wait for some weeks before they can sale their property.


  1. Risk-adverse banks and societies that build up often refuse loans where knotweed is identified. What you may not realize is that they may also refuse a mortgage on adjacent property where knotweed is present, although it’s not the property being sold. Mortgages are usually available to knotweed properties, provided they are treated accordingly.
  1. There are two removal methods of knotweed, namely, physical and chemical. The chemical method takes one season to get rid of the knotweed and cannot be used on construction sites or landscaping works. Chemical method can only be used effectively in winters. The physical method can be used at any time of the year and it will take some days to get rid of the knotweed.
  2. While this may facilitate the sale, the TA6 type now has a particular knotweed problem. Hiding the presence of knotweed could prove to be a costly mistake, as the buyer could have a case for misrepresentation and against the seller and report the acting agent to the authorities for infringement of CPR rules.
