Watch our team in action as we tackle a variety of sandstone cleaning jobs using the specialist DOFF steam cleaning system. The DOFF is a superheated low-pressure system, perfect for restoring sandstone, removing biological growth, moss, algae, and years of built-up grime without damaging the surface. Whether it's a garden wall, building facade, or exterior stonework, the results speak for themselves. Based in East Kilbride, we serve Glasgow and the surrounding areas.
