The wrong method does more damage than the graffiti
On porous heritage brick, soft sandstone, natural stone or a hand-painted mural, aggressive chemicals and high-pressure blasting can permanently etch, bleach or erode the surface — turning a removable tag into a lasting scar. Sensitive-surface removal is about matching the gentlest effective method to the material, so the graffiti comes off and the surface is preserved.
We assess the substrate first, test in an inconspicuous area, and step up only as far as needed — protecting the character and value of historic and specialty surfaces.
Gentle methods we use
- Chemical poultices that draw paint out of porous stone and masonry
- Low-pressure & hot-water systems calibrated to the surface
- Soda & media blasting — soft abrasives that lift paint without cutting the substrate
- Test-first approach — we prove the method in a hidden spot before full removal

Trusted with historic & public assets
- Substrate-first assessment — the method fits the material, not the other way around
- No etching, bleaching or erosion — the surface is preserved
- Mural-safe — careful removal around artwork, plus optional protective coatings
- Fully insured & WorkSafe BC — ideal for municipalities, heritage sites and BIAs
For murals and repeatedly-targeted heritage walls, we often finish with a clear anti-graffiti coating so future tags lift off easily — protecting delicate surfaces long-term.
