Invasive Weed Surveys
A survey is not a sales visit. It is the document that unlocks a mortgage offer, satisfies a warranty provider or lets a developer price groundworks with confidence. Identification by phone or photo is always free — you only pay when you need the paperwork.
Survey types
Photo & phone identification
Send photographs of the plant and we will confirm the species, tell you honestly whether it is a problem, and outline the likely route forward. Most enquiries end here, and many end with good news.
Residential property survey
A qualified surveyor attends, maps the stand, checks boundaries and structures, and produces a written report with a costed management plan — the document lenders and conveyancers ask for during a sale.
Development site survey
Whole-site walkover for developers and contractors, with a plan-based extent drawing, contamination risk notes, a waste classification view and a method statement that fits your groundworks programme.
Portfolio & public sector survey
Programmed surveys across housing stock, estates, highways verges and council land, reported in a consistent format so you can prioritise budget across the whole portfolio rather than site by site.
Targeted treatment, measured results
Stem injection and foliar programmes by qualified operatives.
