Residential property
Japanese Knotweed Excavation and Removal in Residential Property
Our client was the owner of a residential property with very limited access to the rear of the house, which comprised of a decked terrace overlooking a long, narrow garden, which sat several feet lower than the house. There were two infestations of Japanese Knotweed present within the garden. The first was growing underneath and around a garden shed, the second was growing in a rockery that had previously been a pond. The client opted for a full excavation and removal, rather than a treatment solution, as they had plans to redesign the garden.
