What this job actually involves

Knotweed for landlords — how it works here

Knotweed for landlords in St Helens

Older rented streets and former council houses are places where knotweed regularly turns up. We survey single properties and whole portfolios across the borough, carry out treatment and keep a file per address, so a plan exists before a sale, remortgage or tenant complaint.

Managing knotweed across rented properties

Each property gets its own record: survey, photographs, treatment visits, waste notes and guarantee. When a tenant moves out, a sale comes up or a lender asks, the file is already there. For portfolios we keep a single summary sheet too.

Visits are short and we agree access with the tenant directly, so you are not chasing keys. We explain what is going on in plain terms and what they should and should not do in the garden. That avoids well-meant strimming that sets treatment back.

Treating several nearby addresses together is usually cheaper than treating them one at a time, and an early spray programme costs a fraction of an emergency dig before a sale. We give you a figure for each property so you can plan a budget over several years.

Questions about knotweed for landlords

Can the work go ahead with tenants in?
Yes. Visits are short, and we arrange access with the tenant directly.
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.
