KNOTWEED EXCAVATION in London
Excavation is the best option for City of London residents and business who need Japanese knotweed removed for good.
Japanese knotweed is a highly resilient invasive weed species 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.
London’s Knotweed CONTROLLED with herbicide TREATMENT
Chemical Treatment (herbicide) applies a specific herbicide to the plant as part of a planned programme 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, herbicide 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.
WHAT DOES IT COST TO GET RID OF JAPANESE KNOTWEED?
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.
