Check first, spend later

A good share of the plants people send us turn out to be something else.

Snap one leaf and one piece of stem, then send them in. You get an answer for nothing. We only suggest a visit if the plant is knotweed, and you see the price in writing before you agree to anything.

The case for acting early

Left alone, knotweed just keeps expanding

When the canes turn brown in winter it looks as though the problem has passed. It has not. The rhizome carries on underground and the patch is wider every spring.

✓ What that buys

Included in the survey:

  • On-site confirmation of the plant
  • Size, position and spread recorded with photos
  • How far it sits from the house, drains, fences and neighbours
  • A report written for a lender or conveyancer
  • Costed choices: spraying, excavation or a barrier

— What you never get

Things you are never charged for:

  • Looking at a photo, even if it is a harmless plant
  • Mileage within Northwich and the surrounding villages
  • Surprise add-ons after the price is agreed
  • Excavation when spraying would do the job
  • Your own copy of the report

Reports are laid out the way lenders expect to see knotweed recorded on residential property. Take it to any contractor you like.

Japanese knotweed beside a boundary in Greenbank, Cheshire
Knotweed in Greenbank

River banks, canal edges and old works land.

Greenbank is a district of Victorian terraces and small yards close to the River Weaver. Narrow plots, shared alleys and rented houses mean a stand may go unreported for years.

A survey shows whether the stand started on your side of the boundary or came in from beyond it.

Also covering the rest of Northwich — same price, same service.

Before you ring

Questions we get asked

There is knotweed in the shared alley behind our Greenbank terrace. What now?
Find out who owns the alley, since several houses often share it. Photograph the stand, survey your own boundary and keep a dated record.
How do I know if it is Japanese knotweed?
Start with the stems. They are hollow, rather like bamboo, flecked with purple and kink at every joint. The leaves are shield-shaped with a flat edge where the stalk joins. In late summer there are creamy flower sprays, and in winter the dead canes stay up, brown and brittle. The quickest route is to send us a photo.
Is it illegal to have knotweed in my garden?
No, simply having it is not against the law. Allowing it to spread into the wild is an offence, and anything you cut or dig counts as controlled waste. If it passes onto a neighbour's land, a claim against you is possible.
Will knotweed stop me getting a mortgage?
It does not automatically rule you out. Lenders commonly proceed once there is a professional survey, a management plan and an insurance-backed guarantee that can pass to a buyer.
How long does treatment take?
A spraying programme normally runs for three to five growing seasons, with checks afterwards. Excavation is done in days, though it comes at a higher price.
Can I just dig it out myself?
We would not advise it. Small pieces of rhizome are enough to regrow, and the soil cannot simply go in a skip or the garden waste bin.
Does knotweed damage houses?
It finds its way into cracks, drains, paving and flimsy outbuildings. Solid foundations are seldom harmed, but a stand close to a house can still hold up a sale or lower a valuation.
What if it is coming from my neighbour?
Get a survey done so the position and the direction of spread are written down. That record is what you show the neighbour, their landlord or the land owner.

Leave the strimmer where it is.

Local notes

Knotweed notes for Greenbank

Dense canes on a canal or river bank, with stone and brick edging behind.

Greenbank's Victorian terraces and small yards near the Weaver leave few places for a plant to hide, yet knotweed still gets overlooked in narrow alleys, bin yards and corners behind outhouses. Shared access paths make it unclear who is responsible. Look at the foot of boundary walls, gaps in paving and any neglected plot at the end of the row. Because many homes are rented, the stand may go untreated for years simply because nobody knows who should report it.

If you rent here, take dated photos and send them to your landlord or agent in writing, rather than trying to remove it. Owners should check what the neighbouring yards look like, as a stand in a yard two doors along can move under a shared wall or path. Anyone buying should ask the seller about the alley and rear boundaries. A survey records the position clearly and gives each party a common set of facts.
