Preservation Care for Heritage and Modern Stonework
Scottish sandstone and historic masonry require specialized, non-destructive restoration techniques. Environmental pollutants, urban grime, biological growth, and historic paint layers can deteriorate stone surfaces if treated with aggressive pressure washing or harsh chemicals.
Our stone cleaning methodology relies on high-temperature, low-pressure steam systems—specifically the DOFF superheated water process—which thoroughly purifies stone substrates without causing surface erosion, micro-fracturing, or water saturation.
Our Core Stonework Capabilities
- DOFF Superheated Steam Cleaning: Reaches temperatures up to 150°C at the nozzle, effectively vaporising algae, moss, fungi, bitumen, and light paint without damaging delicate stone faces.
- Masonry Paint & Coating Removal: Careful chemical softened application paired with low-pressure steam to strip unwanted, non-breathable masonry paints from historical facades.
- Sample Testing & Panel Demonstration: We conduct controlled test panels for property factors, architects, and private clients to determine the exact thermal and pressure parameters required before full-scale deployment.
- Efflorescence & Staining Treatment: Safe removal of ground salt deposits, carbon crusts, and atmospheric staining from sandstone balustrades, porticos, and facades.
Suitable Surfaces
- Red and Blonde Scottish Sandstone
- Granite, Limestone, and Whinstone
- Decorative Carvings, Mouldings, and Ornamental Stonework
- Historic Ashlar Masonry and Rubble Construction
Survey Note: All stonework projects are evaluated to ensure compliance with local authority heritage guidelines and conservation standards.
