DIY solutions often mask the problem or cause more harm than good, especially if harsh water blasting or generic bleach products are used.Â
Our trained and certified team uses targeted chemical treatment followed by gentle, controlled cleaning methods to:
Break down and kill growth at the root level
Avoid damaging surfaces or protective coatings
Slow down future regrowth by removing organic buildup
AR Plus takes a practical, safety-focused approach to moss and lichen removal, backed by decades of experience and the systems to support larger or more sensitive sites.
Whether it's a one-off moss and mould killer treatment or part of a larger maintenance plan, we work with precision and care to get your property looking its best — and staying that way.
All moss and lichen treatment is performed with the safety of your site, residents, and surfaces in mind.
We use non-toxic surfactants and low-pressure equipment, and establish safe work zones during the treatment process. All AR Plus team members are trained in chemical handling, PPE, and environmental care practices.
Our typical process:
Older roofs and exterior surfaces, especially those made from decramastic tiles, fibre-cement sheeting or Super Six cladding, may contain asbestos. Attempting to clean an asbestos roof yourself, especially with high-pressure water or aggressive scrubbing, can release harmful asbestos fibres into the air or surrounding soil.
AR Plus can assess, test (via a third-party lab), and carry out safe removal or cleaning where asbestos is confirmed.
If there’s any uncertainty about your roof or surfaces, do not attempt to clean them yourself.
Exterior painting works best on clean, dry surfaces. Moss and lichen removal is the ideal prep step for cladding, soffits, fences and trims.
Moss and lichen love the texture of Asbestos roofs, so they may be a warning sign of a larger problem.

Mould also likes damp exterior surfaces. If you're not sure if you have mould, learn more here.
Here are some common questions about moss and lichen killer treatments. If you require more information please contact us.
Eventually, yes, moss and lichen will come back after treatment — but our professional treatments last longer than DIY solutions and help slow future growth by removing spores and residue at the root.
If asbestos is suspected, we’ll stop work and help you arrange asbestos testing. If confirmed, we can safely remove it or refer you to our asbestos services team.
Yes, our moss and lichen killer products are safe for pets and plants — but we’ll ask you to keep pets inside during treatment, and cover any sensitive garden areas as needed. Our products are biodegradable and low-toxic when used as directed.
AR Plus provides safe and effective moss and lichen removal to protect your property and enhance its appearance.
