What this job actually involves

Knotweed excavation — how it works here

Knotweed excavation in Runcorn

Excavation removes the stand and rhizome in a few days, which is why it is chosen before an extension, on a building plot or when a sale is near. It costs more than spraying because of the volume of soil and the licensed disposal. On larger sites, treating or burying soil on site can bring the cost down.

Step by step

How knotweed excavation works with us

  1. Send a photo.

    One leaf and one stem, by message or the contact form. No charge.

  2. We survey it.

    If it is knotweed we visit, measure the stand and note what is close by.

  3. Treat or dig out.

    A spraying programme over several seasons, or excavation if the timetable is tight.

  4. Plan and follow-up.

    A written plan for your records and your lender, with return visits until it stops.

Questions about knotweed excavation

Will the whole garden be dug up?
No, only the area shown in the survey plus a safety margin.
How do I know if it is Japanese knotweed?
Look at the stem first: hollow like bamboo, speckled with purple, and zig-zagging with a node at each bend. Leaves are broad with a flat base. Small cream flowers appear in late summer and the dead canes stay brown through winter. A photo sent to us is quicker than guessing.
Is it illegal to have knotweed in my garden?
Having it is not an offence. Letting it spread into the wild is, and any cut material counts as controlled waste. If it crosses onto a neighbour's land you could face a claim.
Will knotweed stop me getting a mortgage?
Not on its own. Most lenders will lend against a professional survey, a treatment plan and a guarantee that transfers to the buyer.
How long does treatment take?
Spraying usually runs over three to five growing seasons followed by monitoring. Excavation takes days but costs more.
Can I just dig it out myself?
We advise against it. Tiny pieces of rhizome regrow, and the soil cannot go in a skip or the garden waste bin without proper handling.
