I wanted the lichen taken off my colourbond roof without having it ruined by high pressure blasting. Kev was extremely approachable, answered all my questions & fears honestly & quickly. Arrived on time, completed the task in a professional manner & told me it would take 9 months plus for the lichen to come off with the wind & rain after he had killed it. Its now 8 months later and nearly all lichen is off and roof is looking fantastic! Thankyou so much Kevin.
