Our Process for removing Japanese Knotweed in London
Every case of Japanese knotweed treatment in London is different, and we tailor our solutions for each individual infestation. Our proven results come from our attention to detail, and it all starts with simple photo identification:
1. Knotweed Photo Identification
The process begins with identifying knotweed - simply upload a picture and our team of experts will be able to quickly identify if Japanese knotweed is present in your London property.
2. Site Survey & Assessment:
If knotweed is present, we will continue with a site survey where we identify and assess the extent of your London Japanese Knotweed infestation. We provide a detailed report and discuss the most effective treatment options with you.
3. Bespoke Management Plan & Guarantee
After the survey, we will provide you with a personalised Knotweed Management Plan, which includes:
- A detailed report and risk assessment
- A transparent quote
- Treatment details and timelines
Our Management Plans not only comply with the Knotweed Code of Practice to ensure effective treatment but are also backed by varying long-term guarantees with PCA accreditation and mortgage lender compliance for your peace of mind. Optional GPI insurance is also available for extra protection.
4. Treatment & Eradication:
Based on the survey, we’ll design a bespoke treatment plan. Common methods for London-based knotweed eradication include:
- Sifting & Screening: Uncovers hidden Knotweed fragments in soil and materials, enabling early detection and accurate assessment of the infestation.
- Herbicide Treatment: Safe and controlled chemical treatments to destroy Knotweed at its root.
- Excavation & Removal: In more severe cases, we’ll remove Knotweed and its roots through controlled excavation and proper disposal.
- Root Barrier Installation: We implement root barriers as a cost-effective alternative to full excavation and disposal, particularly for larger sites. Some excavation is still required to install the barrier.
5. Ongoing Monitoring:
After the treatment, we’ll monitor the site for several years to ensure the Knotweed doesn’t return. Our guarantees ensure that your London property remains safe from future knotweed infestations.
Why is Japanese Knotweed Such a Problem in London?
London’s high population density and tightly-packed properties make Japanese Knotweed a serious issue. In areas like Islington, Hackney, Kensington and Chelsea, where homes and commercial buildings are often built close together, the presence of Knotweed can have a devastating impact.
One small piece of Knotweed root, or rhizome, can spread up to 7 meters underground, and the plant itself grows rapidly—sometimes up to 2 cm per day. A single square metre of Knotweed can produce up to 250 shoots, all of which can wreak havoc on surrounding infrastructure.
In busy urban areas like Westminster, Islington, or Hackney, where roads, pavements, and driveways are in constant use, Knotweed’s invasive growth can damage essential property structures.
The impact of Knotweed is felt across the capital, causing both structural damage and property value decline, making it essential for homeowners, businesses, and developers across London to address the issue as soon as it’s identified.
Why You Shouldn't Ignore Japanese Knotweed Infestations in your London Property
Ignoring Japanese Knotweed in London can lead to serious consequences that affect both your property and the surrounding environment.
1. Property Damage & Legal Risks
Knotweed can cause severe damage to foundations, driveways, and walls, which is particularly concerning in densely packed areas that are common in London. Failing to manage or remove it could result in hefty repair bills, lower property value, and legal issues.
2. Infrastructure & Environmental Impact
The invasive roots can also damage roads, pavements, and drains in busy parts of London. If left unchecked, it spreads quickly, impacting public spaces where it can disrupt local ecosystems and native plant life.
3. Increased Costs & Long-Term Stress
Ignoring Knotweed only leads to more expensive and complex removal down the line. Early intervention saves you time, money, and stress, ensuring that your London property remains safe, valuable, and compliant with regulations.
Taking action now can protect your property, preserve its value, and ensure you avoid future issues with Japanese Knotweed in London.
