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 Windle
Knotweed in Windle

Old pits, glassworks and canal banks.

Windle sits just north of the centre on ground once owned by the glassmaking Pilkington family, and the area has a patchwork of older houses, later estates and left-over green plots. Redeveloped land of that sort is a common starting place for knotweed.

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 Windle house is on a redeveloped plot. Should we have the garden checked?
It is a sensible precaution. Ground that was cleared, regraded or built on is where knotweed often appears. Spring is the best time for a first look.
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

Redeveloped plots and older houses north of the centre

A trained operative treating a stand in full leaf.

Windle has a mixture of older houses, later estates and small pieces of land that have been redeveloped or left empty. Soil that has been moved or levelled is a recognised way for knotweed to arrive, and a patch can sit unnoticed in a corner of a plot or at the back of a garage. Check borders, the sides of outbuildings and any area where the ground looks recently made up.

If you are buying a house on a redeveloped plot, ask the seller whether knotweed has ever been found on the land. A survey before you commit gives you facts instead of hopes. For existing owners, a photo in spring is a simple first step.
