1. Knotweed Photo Identification
The first step is to identify the presence of Japanese Knotweed. Upload a clear photo of the plant, and our team will identify whether it’s knotweed, allowing us to move forward with the next steps.

2. Site Survey & Assessment
After confirming the presence of knotweed, we conduct a detailed survey on your Manchester property. We assess the extent of the infestation and its potential impact, then provide you with a comprehensive report and a personalized treatment plan.

Why Is Japanese Knotweed a Big Problem in Manchester?
Manchester, with its mix of urban and suburban areas, is especially vulnerable to the spread of Japanese Knotweed. The dense housing developments, roads, and drainage systems create the perfect environment for this invasive plant to spread rapidly. Japanese Knotweed’s underground rhizomes can extend up to 7 meters, and a small fragment can start a whole new infestation.
In particular, areas like Salford, Oldham, and Stockport are prone to severe infestations, with Knotweed causing damage to properties, roads, and even utility services. Left untreated, it can lead to costly repairs, impact property value, and cause disruption to infrastructure.

Why You Can’t Let Japanese Knotweed Spread in Your Manchester Property
Ignoring Japanese Knotweed can lead to severe consequences in both residential and commercial properties across Manchester.
1. Property Damage & Legal Risks
Knotweed can cause significant damage to foundations, walls, and drainage systems. In densely populated areas like Manchester city center and surrounding suburbs, this can result in expensive repairs, lower property value, and legal complications.
2. Infrastructure & Environmental Impact
The roots of Japanese Knotweed can damage roads, pavements, and underground utilities, posing a risk to Manchester’s infrastructure. The plant’s rapid growth can also disrupt local ecosystems and outcompete native species, leading to broader environmental concerns.
3. Increased Costs & Long-Term Stress
Delaying removal can lead to more expensive and complicated removal processes in the future. Act now to minimize costs, reduce stress, and protect your property from long-term damage.
