What this job actually involves

Knotweed survey — how it works here

Knotweed survey in Wigan

The survey confirms the plant on site, measures and photographs the stand, and records how close it is to the house, walls, drains and outbuildings. The written report sets out treatment and removal options with prices, and is the document lenders and solicitors ask for. In a typical Wigan yard or garden the visit takes well under an hour.

Questions about knotweed survey

Do I need to be home for the survey?
Only if we need access through the house. For side or rear access we can agree it in advance.
How do I know if it is Japanese knotweed?
Check the stem first: knotweed stems are hollow like bamboo, speckled purple, with a ring at each joint and a zig-zag shape. The leaves are broad with a straight edge at the base. In autumn you will see little white flower sprays, and in winter brown dead canes. A photo to us is the quickest way to be sure.
Is it illegal to have knotweed in my garden?
Having it is not a crime. Causing it to spread into the wild is, and cut material has to be disposed of as controlled waste. If it spreads to next door, the neighbour may have a claim against you.
Will knotweed stop me getting a mortgage?
Not normally, as long as there is a proper treatment plan in place. Lenders tend to ask for the survey, the plan and a guarantee that transfers to the buyer.
How long does treatment take?
Spraying usually runs for three to five seasons, then monitoring. Digging it out is done in days but costs more.
Can I just dig it out myself?
Best not. Tiny pieces of root regrow, and you are left with soil you cannot put in the green bin or a skip without the right paperwork.
