Heritage thermolysis

TECH

Listed and historic masonry can't take pressure washing or harsh chemicals — both strip the weathered surface that gives old stone its character. Heritage thermolysis is the conservation-grade answer: controlled superheated steam that kills and lifts lichen, algae and moss by heat alone, with no abrasion and nothing left on the fabric. It is the protocol we reach for when a building's age and materials demand the gentlest possible touch.

Heritage thermolysis is the ATH conservation-grade cleaning protocol for listed and historically sensitive fabric, using controlled superheated steam (thermal lysis) to kill and release biological growth — lichen crusts, algae, moss — from soft or friable stone without abrasion or harsh chemistry. It directly answers 'heritage anxiety': the owner's absolute preference for non-destructive, conservation-grade methods that preserve historical authenticity regardless of time or cost. By delivering the lethal effect through heat rather than pressure or aggressive biocide, it removes the coloniser while protecting weathered surface detail and avoiding the substrate damage (spalling, surface-area expansion) that defines Chronostructural Drag.
