Moss, mould, and lichen are common challenges on New Zealand buildings, particularly in damp or shaded areas. Left untreated, they can accelerate deterioration, damage coatings, and increase long-term maintenance costs. Our specialist treatments safeguard roofs, walls, pathways, and other surfaces, keeping your facility safe, functional, and visually appealing.
Expert Moss and Mould Solutions to Protect Your Property and Extend Its Lifespan
Our moss and mould treatments continue to work long after application, providing ongoing protection and reducing the risk of regrowth. Moss and mould treatments can be delivered as a one-off application, alongside exterior painting or high-pressure washing, or incorporated into a comprehensive maintenance solution tailored to your facility. By proactively addressing moss and mould, we help preserve the life of your coatings, maintain structural integrity, and keep your property looking clean and professional.


1. Extended Surface Life
Moss and mould can gradually degrade exterior surfaces, trapping moisture against roofs, walls, and other structures. Specialist treatments remove these growths and create a protective layer that prevents further deterioration, helping to preserve paint coatings, roofing materials, and structural integrity. By addressing these issues early, you can extend the lifespan of your building’s surfaces, reduce the need for repairs, and maintain a professional, well-kept appearance over the long term.

2. Weather-Activated Protection
Unlike basic cleaning methods that only remove surface growth, our moss and mould treatments are designed to provide lasting protection. Once applied, the treatment is activated by New Zealand’s natural weather cycles, with rain helping to carry the product deep into the moss, mould, and lichen. This ensures the treatment continues working long after application, gradually breaking down growth at its roots and preventing regrowth over time. The result is a safer, more effective, and low-maintenance solution that extends the period between cleanings and reduces long-term upkeep costs.
