Japanese Knotweed Removal · Bolton

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.

Developers, landlords and builders

Knotweed on Bolton building land and rented homes

Cleared mill sites, infill plots between the terraces and older rented streets are where a stand gets expensive. We survey the ground, draft the method statement and carry out the spraying or excavation.

Getting rid of it

Spraying, excavation and root barriers for knotweed in Bolton

A spraying programme over a few seasons if you have the time, a dig-out if you do not, and buried membrane where the stand is on land you cannot reach. Every load of waste leaves with the right transfer paperwork.

Why people ring us

Call us if this sounds familiar

Most calls from Bolton start with one of these situations.

The back fence faces a canal, railway or river bank

The back fence faces a canal, railway or river bank

Gardens that back onto an old canal line, a rail embankment or the Croal and Irwell valleys are the ones that meet knotweed most. A survey shows how far it has come over the boundary.

You are about to sell

The TA6 form asks about knotweed outright. Getting a plan together before listing is far less stressful than scrambling once a valuer has mentioned it.

Building work is booked

A foundation trench cut through a stand can drag rhizome across the whole plot. Have it dealt with before the builder turns up.

It has come over from the plot next door

Often from a void house, a rental or a cleared mill site. What you need is a dated record of where it is and when you raised it.

Paving or tarmac is lifting

Paving or tarmac is lifting

Shoots forcing through slabs, tarmac or a block-paved drive hint at rhizome underneath. Plot it before anyone relays the surface.

Also worth a call: red tips by a garage wall, tall canes on the canal or railway bank behind the fence, a TA6 question from the solicitor, a line in the valuation report.

Knotweed in Bolton

Old mill land, river banks and railway cuttings.

Bolton grew on cotton. Hundreds of mills and their chimneys once lined the Croal and the Irwell, rows of terraces packed in around them, and when the mills closed many sites were knocked flat, filled and left to scrub or built over. Add the old canal, the railway embankments, the 1930s estates pushed out onto the hillsides and the damp edge of the moors, and you get plenty of ground where knotweed can take hold unseen.

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

Before you ring

Questions we get asked

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.
Should I cut it back or strim it?
Please do not. Strimming throws fragments about and undoes a spray programme. Leave it standing until someone has looked at it.
What do I have to declare when I sell?
The TA6 form asks the question directly. If knotweed is there, say so and include the management plan. A wrong answer can come back to bite you after completion.
How much does knotweed removal cost?
For a normal garden, a spraying programme typically comes to between £1,000 and £3,000 over its whole run. Digging out costs more because of the soil volume and disposal charges. After the survey you get the figure in writing.
Do you cover all of Bolton?
Yes — Addresses across BL1 to BL6, plus Bromley Cross (BL7), covering the town centre and every district out to the moors and the Wigan and Salford borders.

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.
