Common questions
Your questions, answered
Is the initial quotation really free?
Yes. Initial remote quotations based on your photographs, dimensions and site details are free and without obligation. A site visit may involve a pre-agreed charge.
Do you cover areas outside South Wales?
Yes. We are based in South Wales and consider treatment jobs throughout the UK. Travel considerations are reflected in the proposed quotation.
How long does Japanese knotweed treatment take?
Successful control often requires a multi-year programme and monitoring. The treatment strategy and expected duration depend on the extent of the infestation and site conditions.
Can you identify the weed from photographs?
We can provide an initial opinion from clear photographs. Some plants look similar, so a site inspection or further assessment may be necessary before confirming identification or treatment.
