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.

Japanese knotweed on a bank in Blackbrook
Knotweed in Blackbrook

Old pits, glassworks and canal banks.

Blackbrook sits to the east, between St Helens and Haydock, with the Sankey valley close by and 1950s and 1960s housing alongside open green strips. Valley banks and stream corridors are classic routes for spread.

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

Before you ring

Questions we get asked

Our Blackbrook garden backs onto the Sankey valley path. Is that a concern?
It can be. Linear green routes are lightly managed and the plant moves along them. Check the back boundary in spring and summer.
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.

Put the strimmer back in the shed.

The photo check costs nothing. The report is yours to keep. The price is agreed before any work starts.

Local notes

The Sankey valley path and the green strips beside it

A mini excavator lifting a stand, with the roots stacked on membrane.

Blackbrook lies between St Helens and Haydock, with postwar housing running alongside the Sankey valley and its footpaths. Linear green corridors like this are exactly the routes knotweed follows, and gardens backing onto them are the first to be affected. Look at the back boundary each spring and again in July.

Land along the valley is managed by public bodies and is cut back only now and then. A dated survey of your own side gives you proof of where the stand is and when you reported it. If you are selling, a lender may ask for a plan, so having one ready avoids delay.
