Invasive weed waste clearance in Sandfields, SA1 & St Thomas
Clearing cut invasive plant material, roots and affected soil so it leaves the site lawfully and does not start new growth somewhere else.
How we work in Sandfields, SA1 & St Thomas
- Survey to see what the waste contains and whether soil is affected
- Bag or cover material on site so fragments and seed can't escape
- Keep Japanese knotweed material and soil separate. It is controlled waste and cannot go in household, green or compost waste
- Lawful removal to a facility licensed to accept it, with paperwork kept for your records
- Clean tools, boots and vehicles before leaving

Swansea, Neath and Llanelli named among Wales's worst knotweed hotspots
New figures from the national knotweed heatmap put Swansea city third in Wales with 936 verified sightings, Llanelli fourth with 693 and Neath sixth with 396. Wales as a whole records more than triple the knotweed density of England — which is why early reporting matters so much here.

Swansea Council's knotweed treatment service is open for quotes

North Hill case shows why knotweed between gardens needs early action
A Pleasant View Terrace homeowner spent over a year trying to get knotweed spreading from a neighbouring property contained. Knotweed crossing a boundary is a private legal matter — documenting it early and getting both owners into a treatment plan is far cheaper than a dispute.
