It does not grow through concrete! It does grow through existing fractures or voids in concrete and will, if ignored for years, cause heave and add to fractures. More myths

If knotweed is discovered on or near your property, within 7 metres, most lenders will not provide a mortgage without a professional guaranteed eradication programme in place.

Elcot can provide a mortgage lender accepted 10 year insurance backed eradication programme, within 24 hours, which will allow a buyer to get a mortgage to complete the purchase of your home.

Once we have confirmed that you do indeed have knotweed on your property, either by a site visit or a visual identification via a photograph, it is extremely important to use a professional, experienced company such as ourselves. Trying to handle the removal yourself, and cutting the plant can lead to more aggressive regrowth and spread of your problem, which in the long term could increase the financial impact.

You do not have to remove Japanese knotweed from your land, but you could be prosecuted or given a community protection notice for causing a nuisance if you allow it to spread onto anyone else's property.

Our industry standard eradication programme takes a minimum of 4 years. During this time we will visit, spray and remove parts of the knotweed. We will continue to do this until there is a minimum of 2 years non growth, all at a fixed cost guarantee to you. 85% of our contracts are completed at the 4 year stage, and we then provide you with a 10 year insurance backed guarantee, so that if the knotweed does return, we will continue to treat and eradicate it, again with no extra cost to you or the new home owners (insurances are transferable should you sell the property).

Once you have one of our eradication programmes in place, you can sell your house. You do not have to wait until the end of the treatment to be able to sell or buy a house with knotweed.

Are You a Homeowner or Potential Buyer / Seller with a Mortgage on Hold Due to Japanese Knotweed?

Mortgages & Lending

Most banks and lenders will refuse to provide a mortgage on a property if a surveyor identifies Japanese Knotweed within 7 metres of the habitable space, that means the edge of your property. This could mean that even if Japanese Knotweed is discovered on your neighbours land/garden that a lender or bank will not provide a mortgage on your property!

You may have seen many of the scare stories in the press or on the web which can unnecessarily worry potential buyers, and sellers. However a lot of what you have heard is untrue and elaborated upon.

Japanese Knotweed is just a plant. However, it is a very aggressive plant that can spread easily and quickly, and it has a strong network of roots (rhizome system). But don't panic, it can be treated and killed effectively and without the need to dig up your garden, in most cases.

The most important element of any Japanese Knotweed treatment programme, is that all the affected properties are treated at the same time, to ensure the problem is eradicated and dealt with it. It is very important that neighbours co-operate in this programme.

Most banks will assess Japanese Knotweed infestation on a case-by-case basis, and usually they just need to see that you have taken steps to eradicate the problem by having the following in place:

  • A Japanese Knotweed treatement programme in place from an accredited specialist, like Elcot Environmental, with PCA (Property Care Group) Accreditation..
  • A Full Japanese Knotweed survey report detailing the extent of the problem.
  • A letter from us confirming that a treatment programme has been implemented.
  • Payment Confirmation showing that the treatment programme has been paid for.
  • A 10 year Insurance Backed Guarantee.

When you contact Elcot Environmental to deal with your Japanese Knotweed problem, all of the above is included in our one-off fixed price, along with our 37 years experience with dealing with knotweed and lenders.
