Is that tall red-speckled plant by your Bolton fence knotweed? Message us a photo. We will tell you for free.

Checking a photo costs you nothing. When it turns out to be knotweed, we come and survey it, set out the options for spraying or digging it out, and write the report your lender or solicitor needs to see. Surveys from £275.

No charge until we know

Most of the plants people photograph for us are not knotweed at all.

Snap one leaf, a bit of stem and the whole plant if you can. We answer without sending a bill. We only suggest a visit when it really is knotweed, and you see the price in writing before anything is booked.

Why waiting costs more

A bare patch in winter does not mean it has gone

The canes die back and turn brown from October, and the border looks tidy. Below ground the rhizome carries on. Come the spring it returns wider than before.

✓ What that buys

Inside every survey:

  • The plant confirmed in person, not guessed from a picture
  • The edge of the stand paced out, plotted and photographed
  • How far it sits from the house, drains, sheds and boundaries
  • A written report a lender or conveyancer can act on
  • Prices side by side for spraying and for digging out

— What you never get

Things we do not charge for:

  • Looking at a photo, even if the plant is harmless
  • Mileage to any address in the Bolton borough
  • Surprise extras after you have agreed the price
  • Excavation where spraying would be enough
  • A copy of your own report

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

Knotweed in Great Lever

Old mill land, river banks and railway cuttings.

Great Lever is a close-packed district south of the centre, mostly Victorian terraces built for mill workers, with later infill and the retail ground where Burnden Park once stood. The River Croal runs close by, and the cleared mill and works plots between the streets are easy to find.

A survey shows whether it started in your garden or has crossed from the plot beyond the fence.

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

Before you ring

Questions we get asked

There is a fenced-off empty plot behind our Great Lever terrace. Could knotweed be growing there?
It is quite possible. Cleared mill and works plots are rarely walked, so a stand can build up out of sight and then show up in the yards beside it. Look from an upstairs window in spring and send a photo of anything red-tipped.
How do I know if it is Japanese knotweed?
Start with the stem: hollow like bamboo, flecked purple and bending in a zig-zag at every joint. The leaves are shield-shaped with a flat edge where the stalk joins, and in late summer it throws up sprays of cream flowers. Old brown canes can stand through the whole winter. Sending us a photo is quicker than comparing pictures on your phone.
Is it illegal to have knotweed in my garden?
No, owning land with knotweed on it is not an offence. The law is broken if you let it spread into the wild, and soil or cuttings count as controlled waste. If it moves into a neighbour's garden, they may be entitled to bring a claim against you.
Will knotweed stop me getting a mortgage?
It does not rule one out. Plenty of lenders will go ahead if there is a professional survey, a treatment plan and an insurance-backed guarantee that can pass to the buyer.
How long does treatment take?
Most spraying programmes run for three to five growing seasons, with monitoring afterwards. Digging it out takes days rather than years, but the bill is a good deal higher.
Can I just dig it out myself?
We would not. Small fragments of rhizome regrow, and the soil cannot go in your wheelie bin or be taken to the household waste site.
Does knotweed damage houses?
It pushes into weak spots such as cracks, old drains, paving and lightweight outbuildings. Good foundations are rarely harmed, but a stand close to the building can still knock value off or hold up a sale.
What if it is coming from my neighbour?
Book a survey so the position and direction of travel are recorded. That report is what you show the neighbour, the landlord or whoever owns the plot next door.

Leave the strimmer where it is.

Sending a photo is free. The report belongs to you. We agree the price before we lift a spade or a sprayer.

Local notes

Mill-worker terraces and cleared works plots

A summer stand on a canal embankment, with a stone bridge beyond.

Great Lever is a tight grid of Victorian terraces built close around the mills, with small yards and short back gardens. Between the streets there are plots where mills, works and warehouses were pulled down and the ground was left. Those fenced-off spaces are seldom visited, so a stand can grow for years before it shows over a wall. Look out of the upstairs back window in spring and again in July.

The River Croal runs close to the district, and fragments can travel along its banks. Because the yards are small, a stand only a few metres away can matter a great deal. A survey records exactly where it lies and how far it might reach, and for anyone selling, that report answers the question the buyer's solicitor will ask.
