London has become one of the major hotspots for Japanese knotweed infestation. Japanese knotweed is becoming an increasingly common problem for residents and businesses with a growing number of encroachment cases where knotweed spreads from neighbouring properties. If you live in London Japanese Knotweed Ltd can help you to control and remove knotweed for good.
Excavation is the option for London residents and business that want to remove Japanese knotweed for good. The only way to get rid of Japanese knotweed once and for all is to remove the contaminated ground.
Japanese knotweed is a highly resilient invasive species of weed that is capable of growing new shoots from its root network. These special roots are known as rhizomes, and even a tiny piece as small as 0.5g is capable of allowing the infestation to regrow. With root systems that bury deep into the ground, excavation of the contaminated soil is the best way to completely remove the infestation.
A popular option in London – especially smaller spaces is Chemical Treatment (herbicide). The goal of herbicides is to control its growth and stop the spread. Japanese knotweed treatment will exhaust the plant’s ability to grow and will force it into a dormant state .
Over the course of the plan, the treatment programme will prevent the plant producing aerial growth and additionally, prevent the rhizomes from growing further. If the knotweed area is likely to be disturbed physical removal of the knotweed may be required instead.
Treatment methods include stem injection, herbicide spray and leaf wiping. Our herbicide programmes are packaged within a Knotweed Management Plan (KMP), which comes with an Insurance Backed Guarantee.
The average cost to remove Japanese knotweed in London varies, depending on the methods involved and the size of the affected areas. If it is identified and dealt with promptly, the costs of removing Japanese knotweed can be kept to a minimum. Long-term herbicide treatment is usually the most cost-effective control method. Our professionally delivered herbicide treatment programme will provide successful chemical control of Japanese knotweed within a period of 3-7 years.
Excavation of Japanese knotweed costs more than herbicide treatment due to labour, materials, waste removal and reinstatement costs. However, it ensures complete Japanese knotweed removal allowing free use or development of the property. We provide cost-efficient excavation due to our extensive experience whilst minimising waste volumes.
Following our professional surveys we will provide you with a no-nonsense, comprehensive report with no-obligation recommendations and quotes.
There are lots of theories on the internet and in local London communities about how to remove Japanese knotweed – from using a lawnmower to using a flamethrower. The truth is that there is no way to deal with Japanese knotweed yourself. You need to have a plan in place to control the Japanese knotweed, or you need to excavate it to get rid of it once-and-for-all.
As knotweed is an invasive species that is classed as “Controlled Waste” it can only be removed by licensed organisations. It must be disposed of safely at a licensed landfill site by a registered waste carrier. Carelessly disposed of, knotweed can cause an infestation. Due to this, and the legal issues surrounding knotweed, we do not advise you try to undertake this operation yourself. Contact us instead.

In this case study, we look at some of the challenges that a large construction operation in Wembley, London had when they ran into invasive weeds Japanese knotweed and Giant hogweed. Having successfully tendered for this project we were awarded the contract to eradicate stands of Japanese knotweed and Giant hogweed from a large site next to the river Brent. As these plants are listed within Section 14, Schedule 9 Part II of the Wildlife & Countryside Act 1981, once their presence was recorded a control strategy was recommended. The works involved survey, treatment and excavation. Read more…
