Knotweed removal across South & West Wales.

Cardiff, Swansea, Newport, Bridgend & Carmarthenshire

Japanese knotweed is endemic across South and West Wales — a legacy of coal-mining, copper smelting and unmanaged riparian corridors along the Taff, Usk, Tawe and Tywi. Our Cardiff and Swansea crews cover every CF, NP and SA postcode in the region.

Why South Wales is hit so hard

Mild, wet Atlantic weather, dense Victorian terraces backing onto railway embankments, and decades of post-industrial fly-tipping make South Wales one of the worst affected regions in the UK. Mortgage-blocking surveys are a weekly occurrence in CF11, CF14, NP19 and SA1.
