Digging out the stand and its roots in a matter of days.
Free photo ID check · Mon–Fri 8am–6pm, Sat mornings
Excavation lifts the stand and rhizome in days instead of years, which suits plots ahead of an extension, development land or a sale against the clock. It costs more than spraying because of the volume of soil and the licensed disposal. On larger sites, treating or burying soil on the land can bring the bill down.
The survey plot sets the area, and a margin goes around it. Access for a machine, space to stack soil on membrane and the route to the road all affect the method. In tight terraced gardens a small tracked digger or hand digging may be the only option.
Knotweed soil is controlled waste, so it needs a transfer note and a site licensed to take it. On bigger plots, burying it deep on site under membrane or treating it in a cell can cost less, but needs a plan agreed in advance. You get copies of every record.
The hole is backfilled with clean material and the area is watched for the next season. A small amount of regrowth is not unusual and is dealt with by spot treatment. The paperwork from the dig is what a buyer's solicitor will later want to see.




One leaf and a length of stem will do. Use the contact form or message us. No cost.

If it is knotweed we come out, measure the stand and record what is near it.

Treatment over several seasons, or excavation when the calendar will not wait.
