Overview
Heritage cleaning removes contamination from historic structures using dry ice blasting, propelling solid CO₂ pellets that convert instantly to gas on impact, lifting deposits without water or abrasive residue.
Each project starts with a site survey and test patches. Air pressure, pellet size and stand-off distance are calibrated to the material and condition, keeping preservation the primary objective.
Typical applications
- Soot and smoke staining from fire damage
- Atmospheric pollution and carbon build-up
- Grease, tar, light paint and aged varnish
- Carved timber, decorative stonework and mouldings
- Stone and brick facades, timber beams and joinery
- Churches, museums and listed residences
Key benefits
- Dry process — no moisture into porous masonry or timber
- Adjustable pressure for surface sensitivity
- No abrasive media embedded in joints
- Reduced airborne dust versus traditional abrasives
- Reaches recesses and intricate detail without scouring
- Efficient mobilisation for phased conservation
