Our Stone Cleaning Process

Our approach is safe, precise, and tailored to your property:

Site Survey & Stone Assessment

We begin with a thorough inspection to identify surface types, staining, previous treatments, and any structural concerns. This allows us to recommend the most suitable cleaning method for each area of stonework.

Method Selection 

Our methods include low-pressure steam cleaning (DOFF), controlled chemical treatments (where appropriate), and non-abrasive hand-cleaning for fragile surfaces. We always spot-test and work conservatively to preserve the material.

Stain, Algae & Carbon Removal

We target and remove atmospheric pollutants, algae, moss, rust, and biological stains, ensuring a clean finish without damaging the stone’s surface or pointing.

Final Quality Inspection

Our team ensures every surface is clean, safe, and left in a condition that reflects the professionalism of your property.
