Professional Stone Facade Cleaning London

Every building is different, so we price after a free site survey that considers the facade area, stone type, level of soiling and access requirements. As a guide, most residential frontages start from a few hundred pounds, while larger commercial facades are quoted per square metre once we’ve assessed scaffolding or access needs.

Yes. We use graduated, low-pressure methods and stone-appropriate cleaning agents, and always test on a discreet area first. For listed and historic buildings we work within conservation guidance and can liaise with your architect or conservation officer where required.

A typical house frontage takes one to two days. Larger commercial buildings vary depending on scaffold access, but we’ll give you an accurate timeline as part of your quote.

No, when carried out correctly. We match pressure, dwell time and chemistry to your specific stone type, avoiding the aggressive sandblasting or overly acidic treatments that can scar softer stones such as limestone and sandstone.

Yes. We use biodegradable, pH-balanced cleaning products wherever possible and always follow safe water run-off practices, particularly important on street-facing commercial buildings.

Yes, this is one of the most common issues we treat. Black gypsum crusts and traffic soiling sit on the surface of the stone and respond well to our steam and low-pressure cleaning systems.

It depends on the height and access of the building. Ground and first-floor work can often be completed from a cherry picker or ladders, while taller facades may require scaffolding, which we can help coordinate.

Most London buildings benefit from a full clean every five to ten years, though this varies with orientation, traffic exposure and whether a protective sealant has been applied.

Yes, every quote begins with a free, no-obligation site survey so we can assess the stone type, condition and best cleaning method before providing a fixed price.

Yes, we carry full public liability insurance and can provide certificates and risk assessments for property managers, landlords and commercial clients before work begins.

Yes, we offer optional breathable, stone-appropriate sealants that help resist future staining and biological growth while allowing the stone to breathe naturally.
