Professional Moss & Lichen Control in Feilding & Manawatū
Moss, lichen, and black fungi aren't just unsightly - their root systems actively eat into roofing materials, lift tiles, trap moisture, and degrade timber decks and concrete. Pressure washing alone doesn't eliminate the underlying spores. Our specialised slow-release moss and lichen treatments kill bio-growth at the root, allowing natural weather action to gently wash away debris while protecting your surfaces for up to 24 months.
Service Breakdown
Roof Moss & Lichen Soft Treatments
Roofs require gentle, non-destructive chemical care. We apply targeted roof-safe bio-treatments that soak into concrete tiles, decramastic tiles, colorsteel, and asphalt shingles. Over the following months, rain naturally washes away dead organic growth without breaking factory seals or stripping paint finishes.
Deck & Patio Bio-Inhibitor Application
Timber decks and stone paving are susceptible to micro-algae that turn dangerously slick in damp conditions. Our anti-fungal treatments penetrate deep into timber grain and stone pores, neutralizing living spores and creating a long-lasting barrier against regrowth.
Fence, Cladding & Wall Bio-Clean
Plaster finish walls, timber boundary fences, and brick retainers often develop stubborn lichen patches that chip away materials over time. We apply specialized low-toxicity chemical sprays that break down the lichen’s structural bond, restoring surface cleanliness safely.
Preventative Annual Maintenance Spraying
Don't wait for heavy moss crusts to form. We provide annual, scheduled preventative spraying programs for residential properties and lifestyle blocks across Manawatū—ensuring your roof, pathways, and structures stay permanently free from green algae and black lichen.
