MouldStop Retrofit Service Network
A franchised network of trained installers who deploy targeted mechanical ventilation retrofits (extract fans, humidity sensors, smart vents) paired with behavioural moisture audits. Installers diagnose the specific moisture source (cooking, bathing, laundry, external damp) and install the minimum viable extraction system—not whole-house heating upgrades—then train homeowners on condensation-reducing habits. Revenue comes from installation fees and ongoing maintenance contracts.
