Domestic Treatment & Removal

Japanese Knotweed can cause structural damage to your property so it’s important to ensure its dealt with as quickly and professionally as possible; particularly if you’re applying for a mortgage or looking to sell your home.

What is Knotweed?

Knotweed is an invasive plant species that can grow up to 10 cm a day; so it’s vital to call us straight away to ensure it’s looked at immediately. But how can you tell if it’s Knotweed you’re faced with? Here are some key identifiers:

  • Knotweed tends to appear in the early Spring with purple shoots and green leaves
  • Fully-fledged knotweed has distinctive cream flowers and spiky stems
  • The bark tends to be knotty with a dark brown hue

Whilst there’s not yet been any reports of houses being destroyed by Japanese Knotweed, it does pose a significant threat to your local environment and you’ll likely have to spend hard-earned cash to unnecessarily fix parts of your property that may be damaged if the problem is ignored.

Removal is tricky and you can be prosecuted for insufficient disposal; that’s why it’s so important to get Sussex Knotweed on to the issue as quickly as possible to ensure all legal guidelines and procedures are being adhered to. Our specialists will ensure the species is removed safely, speedily and in accordance to all environmental guidelines.

If you’re a home-owner looking to sell, you must declare any Knotweed issues which can cause the house price to drop; another reason to get the problem sorted as quickly as possible. Many residential mortgage lenders require a specialist survey that outlines any potential risk or damage to a property if Knotweed has been identified.We offer consultations and site surveys before any work is carried out to ensure we’re using the appropriate removal methods and will always talk to you ahead of removal to make sure you’re happy that we’re performing ecologically.


In most cases, we’re able to completely eliminate any trace of Japanese Knotweed from a residential property. Our chosen method of eradication is excavation, dependent on access to the affected site.

There’s more than meets the eye with Japanese Knotweed; in addition to the plant you can see overground, the species has underground rhizomes and roots that you cannot. Therefore, professional excavation is necessary to ensure complete removal. This can be quite a big project with some roots on record as being 7 metres wide and 3 metres deep so you must be prepared for this.

We’ll excavate the soil to the required depth, assess the spread of the Knotweed and act accordingly. We’ll always dispose of the waste in a controlled manner and in accordance to the Environmental Protection Act 1990.

We’ve experience at working across Sussex, Surrey, Brighton and Kent so if you want to find out more about our excavation methods, call the Sussex Knotweed team on 01273 499 029 or email
