Look first, pay later

Plenty of the plants we are sent turn out to be harmless.

Take a picture of one leaf and a section of stem, then send it across. You hear back without being billed. A visit is only suggested when the plant really is knotweed, and the price is put in writing before you agree to anything.

Why not to wait

Knotweed does not go away when you ignore it

By late autumn the stems turn brown and the garden looks clear. Underground the rhizome is still spreading, and the stand comes back bigger once the weather warms.

✓ What that buys

What the survey covers:

  • The plant identified on site, not just from a photo
  • The stand's edges measured, mapped and photographed
  • Distances to the house, drains, outbuildings and neighbours
  • A report written so a lender or conveyancer can rely on it
  • Priced choices between spraying and excavation

— What you never get

What you will not be charged for:

  • A photo check, even when it is a harmless weed
  • Travel anywhere in the St Helens borough
  • Extras added after the price is agreed
  • Digging where a spray programme would do
  • Your own copy of the finished report

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

Developers, landlords and builders

Knotweed on St Helens development land and rental property

Former colliery, glassworks and brick-pit sites, infill plots and older rented streets are where a stand turns expensive. We survey the ground, write the method statement and carry out the spraying or excavation.

Dealing with it

Knotweed spraying, digging out and root barriers in St Helens

A spray programme over several seasons when time allows, excavation when it does not, and a buried membrane when the stand sits beyond your boundary. All waste leaves with the correct transfer paperwork.

Why people ring us

Call us if this sounds familiar

Most enquiries from St Helens start with one of these.

The garden borders the canal path or a railway line

The garden borders the canal path or a railway line

Back fences that face the Sankey canal corridor, a rail cutting or a strip of unused land see knotweed most often. A survey shows how far past the boundary it has got.

Pink-red tips appearing from April beside a garage, a greenhouse or the edge of the drive are the first thing most people notice.

The TA6 asks about knotweed straight out. A management plan prepared in advance is far easier than finding one once a valuer has raised it.

Foundations dug through a stand can carry rhizome across the whole plot. Have it dealt with before the builder arrives.

It is coming through from the next plot

Often from an empty house, a rental or a gap site. You need a dated record of where it sits and when you reported it.

Shoots forcing up through tarmac, slabs or block paving suggest rhizome below. Plot it before anyone relays the surface.

Also worth a call: red shoots by a garage wall, tall canes along the canal or railway behind the fence, a TA6 question from the conveyancer, a note on the valuation.

Knotweed in St Helens

Old pits, glassworks and canal banks.

St Helens was built on glass, coal and chemicals, and the land remembers all three. Pit heads, glassworks, alkali tips and clay pits were levelled over the decades and either built on or left to scrub, so many streets sit beside ground that was filled, regraded or abandoned. Add the Sankey canal, several railway lines and a great deal of 1930s to 1960s council and private housing, and you have the sort of broken, edgy land that knotweed settles on before it reaches gardens.

A survey shows whether the stand began in your garden or arrived from the land next door.

Before you ring

Questions we get asked

How do I know if it is Japanese knotweed?
Look at the stem first. It is hollow like bamboo, spotted with purple, and kinks in a zig-zag at each node. Leaves are shaped like shields with a flat base, and creamy flower clusters appear in late summer. Dead brown canes can remain upright all winter. A photo sent to us is faster than matching pictures online.
Is it illegal to have knotweed in my garden?
Having it on your land is not a crime. The offence is letting it spread into the wild, and any soil or cuttings are treated as controlled waste. If it crosses into a neighbour's property they may have grounds for a claim against you.
Will knotweed stop me getting a mortgage?
Not by itself. Many lenders will proceed when there is a professional survey, a treatment plan and an insurance-backed guarantee that can transfer to the buyer.
How long does treatment take?
A spraying programme normally lasts three to five growing seasons, followed by monitoring. Excavation takes a few days but costs noticeably more.
Can I just dig it out myself?
We advise against it. Tiny pieces of rhizome regrow, and the soil cannot go in the household bin or to the council tip.
Does knotweed damage houses?
It exploits weak points such as cracks, old drains, paving and light outbuildings. Sound foundations are seldom at risk, but a stand close to the house can still reduce a valuation or delay a sale.
What if it is coming from my neighbour?
Arrange a survey so the position and the direction of spread are on record. That report is what you show the neighbour, or the landlord or owner of the plot next door.
Should I cut it back or strim it?
No. Strimming scatters fragments and undermines a spray programme. Leave it standing until it has been looked at.
What do I have to declare when I sell?
The TA6 asks directly. If knotweed is present, say so and attach the management plan. A wrong answer can come back on you after completion.
How much does knotweed removal cost?
For an ordinary garden a spray programme often lands between £1,000 and £3,000 across its full length. Excavation costs more because of the soil volume and disposal. Once we have surveyed, you receive the price in writing.
Do you cover all of St Helens?
Yes — Addresses across WA9, WA10 and WA11, plus Rainhill (L35) and Newton-le-Willows (WA12), from the town centre out to the borough edges.
