Japanese Knotweed in Oldham

Japanese Knotweed removal in Oldham

There is a lot of Japanese knotweed in Oldham and the surrounding Manchester area. This often runs along water courses, but it can appear in gardens, brown field sites and in commercial settings. With over 25 years’ experience we can help you with any of your Japanese knotweed problems.

Japanese knotweed can establish itself through stem cuttings or very small pieces of the root (rhizomes) being deposited within the soil. This can take place through them being moved by animals such as foxes and badgers. We also see human activity, whether deliberately or not, being the cause of the spread of Japanese knotweed in Oldham. We especially see evidence of this on brown field sites where it has been dumped.

Eradication of Japanese Knotweed In Oldham:

Eradication usually takes place by two primary methods; both are successful and there are

advantages to both methods:

Chemical treatment – This involves 9 visits over three years in August, September and October of each year. This is followed by two years of monitoring and the site can then be certified as being free of Japanese knotweed.

Excavation – The rhizomes can be growing up to 3m deep and 7m horizontally, so when we excavate we usually use a minimum 13 ton digger. The soil is classified as “Controlled waste” and as such you must be licenced to remove it from site. If you are not, you can face a fine of up to £20,000! We can either back fill the hole created by the excavation or leave it for the clients’ ground workers to backfill with waste from the site e.g. soil from where the foundations are being dug out. This then keeps the cost down. Excavation is the ideal solution if you are developing the site and can’t afford to wait three years for the chemical treatment to be effective.

Cost of Removing Japanese Knotweed in Oldham:

These vary hugely depending upon the area covered by the Japanese knotweed, including the age, density of stems, and whether it is covering multiple properties and ease of access. Typically, the implementation of a Management plan that recommends chemical treatment would cost £3,000 – £5,000, but we have completed jobs that are as little as £2,000 and others that have cost over £20,000 for chemical treatment.

For excavation of Japanese knotweed then the cost is typically £10,000 to £15,000. However, we have also completed large commercial projects where the cost was in excess of £100,000! As a commercially minded company with the client at the heart of what we do we aim to recommend the very best and most cost effective way of dealing with the Japanese knotweed on a case by case basis ensuring the client gets a personalised treatment management plan.
