For surfaces that keep going green no matter how often they’re washed, Thermatech offers a smarter approach. Using controlled heat to neutralise organic growth, it helps tackle the cause of staining — not just the visible layer — delivering a cleaner finish that typically lasts longer than a quick surface rinse.
Thermatech is a heat-based exterior cleaning method designed to break down organic growth such as algae, moss and lichen. Rather than relying purely on high pressure, heat treatment targets the root of the problem by neutralising spores and biofilm that can quickly return in shaded or damp areas.
This approach can be particularly effective on surfaces that are prone to repeat staining — for example patios, paths, stonework, exterior walls and other areas exposed to moisture. We assess the material, its condition and the level of contamination before selecting the most suitable method, keeping the finish in mind while still achieving a visibly cleaner result.
Thermatech can also be a great option where a more controlled clean is preferred, helping lift stubborn growth without aggressively scouring the surface.
