Why Act Now
Unmanaged knotweed is a commercial liability
On development sites, commercial property and managed estates, Japanese Knotweed is more than a weed: it's a legal, financial, and planning risk that compounds the longer it's left untreated.
Legal
Liability & nuisance claims
Allowing knotweed to spread to neighbouring land can trigger private nuisance claims and enforcement action. A managed, documented approach protects you.
Value
Lending & valuation impact
Lenders and valuers flag knotweed on any property or site, stalling sales, refinancing and mortgages. A treatment plan with guarantee restores buyer and lender confidence.
Planning
Compliant sign-off
Planning conditions and lender requirements increasingly demand a knotweed management plan. Our reports satisfy local authorities and keep programmes and property transactions moving.
Our Services
The right treatment for your site, property & timeline
Every site and property is different. Left unchecked, knotweed can damage foundations, drainage, boundary walls and hard surfaces in built environments, not just development plots. We match the method to your programme, budget and end use, from long-term management to rapid, development-ready remediation.
Assess & Plan
Management Plan
A surveyed, costed and insurance-backed plan for sites and properties that satisfies lenders, valuers and planning conditions.
Treat
Herbicide Treatment
Targeted, professionally applied herbicide programmes that control and eradicate growth around structures, boundaries and hard surfaces cost-effectively.
Remediate
Dig & Sift
Excavation and screening of contaminated soil for fast, development-ready clearance on tight programmes.
Contain
On-Site Burial
Compliant on-site burial and encapsulation that removes off-site disposal cost and keeps contaminated material safely contained.
