The core service list

Three core services. One team.

Every job is run end-to-end by the same specialist you first speak to. No call-centre handoff, no subcontracted unknowns.

01

Documented programme

3–5 year programme

Management Plan

A structured, lender-accepted Knotweed Management Plan that records the methodology, works, photographs and herbicide log. Designed to satisfy mortgage applications and give you a clear path to verified clear.

Best for

Homeowners, landlords and sellers who need a documented, mortgage-friendly route to clearance.

What's included

  • Lender-ready documentation
  • Dated photographic record
  • Annual monitoring & re-treatment
  • Signed completion certificate
02

In-situ control

3–5 year programme

Containment Plan

When excavation isn't practical or the budget is tighter, we design a containment programme to control the stand in place. Clear boundaries, scheduled herbicide treatment and annual reporting keep the site managed and the liability documented.

Best for

Sites where full removal isn't needed or practical right now.

Transfer liability

Project dependent

Pass on ownership & accountability

Best for

Developers, contractors and vendors who want risk transferred and the site unencumbered.

Mobile screening machine separating rhizomes from excavated soil on a development site

On site screening 180 tonnes of soil to remove knotweed rhizomes.

Excavation & screening

When the site needs the heavy kit brought in.

For development sites, land transfers or urgent clearances, we excavate and screen the affected soil to physically remove rhizomes. This mobile screening machine was brought in to process 180 tonnes of soil — separating the viable spoil from the knotweed material before controlled disposal.

Not seasons — for fast handovers

From the field

Recent work, straight from site.

A few shots from jobs we've been out on — what knotweed actually looks like on the ground, and what it takes to deal with it properly.

Damage & encroachment

Why a quick survey is never wasted money.

These are real photos from sites we've attended across Norfolk, Suffolk and the wider East. Every one started as “probably nothing”.
