Property Value Impact

    Japanese Knotweed can reduce your property's value, but the impact varies significantly based on several factors.

    Without Treatment

    • • Value reduction: 5-15% typical
    • • Some buyers won't consider property
    • • Limited mortgage options
    • • Longer time on market
    • • Lower negotiating position

    With Professional Treatment

    • • Value impact: 0-5% with guarantee
    • • Most buyers will proceed
    • • Full mortgage availability
    • • Normal selling timelines
    • • Strong documentation

    Factors That Affect Value Impact

    • Proximity to buildings: Knotweed within 7m of structures is most concerning
    • Treatment status: Untreated vs. in-treatment vs. completed
    • Guarantee available: Insurance-backed guarantees reassure buyers
    • Location: Different areas have varying buyer awareness
    • Property type: Higher-value properties may see larger absolute reductions
