Treatment and removal

These are not hidden extras — they are different jobs. If one applies to your property we say so before we attend, not afterwards.

No work starts until you hold a written price.

Questions about cost

How much does a knotweed survey cost in St Helens?
From £275 for a typical residential garden, including the site visit and written report. Treatment and removal are quoted separately, in writing, before any work.
How much does treatment cost?
Herbicide programmes for a typical garden often cost in the region of £1,000 to £3,000 spread over several years. Excavation is faster and more expensive — from several thousand pounds upwards depending on volume and access.
Do you charge to identify it from a photo?
No. Send a clear photo of the leaves and stems and we will tell you whether it is knotweed. If it is not, there is nothing to pay.
