Stone and Masonry
Cleaning

Clean heritage stone, brick, and masonry of biological growth, atmospheric staining, salt crystallisation, and old coatings without mechanical abrasion or chemical contamination.

Historic stone buildings, churches, civic structures, and monuments accumulate decades of atmospheric soiling, biological growth, and sometimes misguided paint applications. Cleaning them properly — without damaging the stone or introducing contaminants that accelerate future deterioration — is a specialist task that conventional cleaning methods handle poorly.

Laser cleaning removes biological growth, black carbon crust, old paint, and atmospheric staining from stone surfaces with a precision that no other method can match. The laser vaporises the contaminant layer without touching the stone beneath — preserving carved detail, original texture, and the natural stone surface that gives heritage buildings their character.

We work with building owners, heritage conservation specialists, and architects on projects ranging from single-building facade cleaning to multi-building civic restoration programs. Our mobile equipment means no scaffolding is needed for assessment — we can provide a site survey and quote quickly, then mobilize when the project is ready.

Applications

  • Heritage & historic stone buildings
  • Church facades & monuments
  • Limestone & sandstone restoration
  • Granite & marble surfaces
  • Brick facades & chimneys
  • Retaining walls & boundary walls
  • Civic statues & memorials
  • Courthouse & civic buildings
Why laser for stone and masonry

The conservation-grade
cleaning method

Zero mechanical contact
Grinding wheels, wire brushes, and abrasive blasting all contact the stone surface and progressively erode it. Laser cleaning is a non-contact process — the beam never touches the stone, so surface detail and texture are perfectly preserved.
No chemical contamination
Acid-based cleaners etch carbonate stones like limestone and marble. Alkaline cleaners can cause salt crystallisation that damages the stone from within. Laser cleaning uses no chemicals — just light.
Selective and controllable
The same laser system can clean biological growth (lichen, moss, algae) at low power, then switch to removing old paint or coating at higher power — without changing equipment or masking adjacent surfaces.
Approved for heritage use
Laser cleaning has been used on historic buildings, statues, and monuments across the US and internationally for over 20 years. It is specified by heritage conservation bodies precisely because it is the least invasive method available.
