How we work

Half the plants we are sent are not knotweed. We say so.

A photo costs you nothing. If it is bindweed or dogwood, you hear that the same day. If it is knotweed, you get a survey, a written plan and a price before anything is sprayed or dug.

Why sooner is cheaper

What leaving knotweed another season costs

Knotweed does not die back for good in winter. The rhizome keeps spreading underground.

✓ What that buys

Every survey includes:

  • A site visit to confirm it is Japanese knotweed
  • Measurement of the stand and nearby structures
  • A plan of where it is and where it is likely spreading
  • A written report with photographs, suitable for lenders
  • Treatment and removal options, each with a price

— What you never get

You will never be charged for:

  • Telling you from a photo that it is not knotweed
  • Travel within Warrington
  • A price that changes after the survey
  • Pressure to excavate what can be treated
  • Access to your own report

Surveys follow the RICS guidance on Japanese knotweed and residential property. Take it to any contractor you like.

Landlords and developers

Knotweed on Warrington development plots and rental property

Knotweed holds up groundworks, complicates disposal and turns up on inspection reports. We survey, plan and treat or remove it for developers, landlords and managing agents.

Why people ring us

Call us if this sounds familiar

Most calls start with one of these.

It is coming through the fence

It is coming through the fence

Warrington gardens backing onto canal, rail or waste ground are where most of it starts. Knowing how far it has come is step one.

Red shoots in spring

Asparagus-like red spears from April, often through gravel, paving or cracks along a wall.

You are selling

The TA6 form asks directly about knotweed. A management plan lets you answer it and keep the sale moving.

Planning an extension

Planning an extension

Digging foundations through a stand spreads it. It needs dealing with before the groundworks start.

Not sure it is knotweed

Bindweed, dogwood and Russian vine are often mistaken for it. A photo usually settles it.

You manage property or land

Rental houses, blocks and development plots need a record and a plan that stands up to a lender or buyer.

Also worth a call: canes by the canal or railway fence, shoots through a driveway, a TA6 question you cannot answer, a lender asking for a plan.

Japanese knotweed growing over a garden fence in Warrington
Knotweed in Warrington

Canal, river and railway land runs right through town.

Warrington sits where the Mersey, the Manchester Ship Canal, the Sankey Canal and several main railway lines meet — exactly the kind of corridors Japanese knotweed spreads along. It turns up in back gardens that border the old canal and rail land, on the edges of the post-war estates and on development plots across the town.

Most stands we see started on a boundary. The survey shows where yours is heading.

Before you ring

Questions we get asked

How do I know if it is Japanese knotweed?
Look for hollow, bamboo-like stems with purple speckles that grow in a zig-zag from node to node, and large shield or heart-shaped leaves with a flat base. In late summer it carries creamy-white flower tassels; in winter the dead canes stay standing, brown and brittle. Send us a photo and we will tell you.
Is it illegal to have knotweed in my garden?
No. It is not an offence to have it on your land. It is an offence to cause it to grow in the wild, and knotweed waste is controlled waste that must be disposed of properly. Letting it spread onto a neighbour's property can lead to a private nuisance claim.
Will knotweed stop me getting a mortgage?
Usually not, if there is a professional management plan in place. Most lenders want to see a survey, a treatment plan and, often, an insurance-backed guarantee before they will lend.
How long does treatment take?
Herbicide treatment typically runs over three to five growing seasons, with monitoring afterwards. Excavation removes it in days but costs more.
Can I just dig it out myself?
It is not recommended. Fragments of rhizome as small as a fingernail can regrow, and the soil becomes controlled waste. DIY digging usually spreads it.
Does knotweed damage houses?
It exploits existing weaknesses — cracked paving, drains, garden walls, conservatories and outbuildings are most at risk. Serious damage to sound foundations is less common than often claimed, but lenders and buyers still treat it seriously.
What if it is coming from my neighbour?
Start with a survey that records where it is and where it is spreading from. That evidence is what a conversation with the neighbour — or a claim — rests on.
Should I cut it back or strim it?
No. Cutting and strimming scatters fragments that can regrow, and it weakens the effect of herbicide treatment. Leave it until it has been assessed.
What do I have to declare when I sell?
The TA6 property information form asks whether the property is affected by Japanese knotweed. If it is, you should say so and provide the management plan. Answering incorrectly can lead to a misrepresentation claim.
How much does knotweed removal cost?
Herbicide treatment programmes for a typical garden often cost in the region of £1,000 to £3,000 over several years. Excavation is quicker but can run from several thousand pounds to £20,000 or more on larger sites. A survey tells you which applies.
Do you cover all of Warrington?
Yes — All Warrington postcodes (WA1–WA5), plus Lymm (WA13) and Culcheth (WA3).

Do not cut, strim or dig it until you know what it is.
