Important Information for Homebuyers:
When conducting a standard conveyancing survey, most surveyors typically do not inspect garden areas for Japanese Knotweed. If a surveyor notices large amounts of green shrubs or trees around the property, they recommend bringing in a specialist Japanese Knotweed surveyor to ensure a thorough investigation.
Notably, 95% of surveys reveal that no Japanese Knotweed is present, giving you peace of mind. However, having a dedicated Japanese Knotweed survey can help you avoid costly surprises and ensure the property is free from this invasive plant.
As experts in identifying and managing Japanese Knotweed, we provide detailed surveys to protect your investment.

The History of Japanese Knotweed & Its Spread in Manchester, the Northwest & Birmingham
Japanese Knotweed (Fallopia japonica) was first introduced to the UK in the 19th century as an ornamental plant. However, its aggressive growth and invasive nature soon became a serious issue, particularly in urban areas. Over time, it has spread extensively across cities like Manchester, Birmingham, and throughout the Northwest, thriving in disturbed soil and transport corridors such as railway embankments and riverbanks.
Due to its deep and resilient root system, Japanese Knotweed removal requires specialist treatment. Left untreated, it can cause structural damage to buildings, reduce property values, and make mortgage approvals difficult. Homeowners and property developers often struggle with its rapid spread, making professional knotweed treatment essential.
At Japanese Knotweed Plus, we offer a free survey to assess the extent of the infestation and recommend the most effective treatment plan. Our Japanese Knotweed treatment programs include professional herbicide treatments and a 10-year insurance-backed guarantee for peace of mind.
