Key Reasons for cleaning stonework:

 

​Preventing Structural Decay and Erosion: Environmental pollutants like sulfur dioxide can react with stone to form a harmful "black crust" that clogs pores and leads to blistering and spalling. Additionally, organic growth like moss and algae produces acids that dissolve stone minerals and traps moisture, which can cause freeze-thaw damage in colder months.

 

Improving "Breathability": Stone is naturally porous and needs to allow moisture to evaporate from the surface. Over time, layers of dirt, soot, and improper coatings can seal these pores. Regular cleaning ensures the stone can properly "breathe", which is essential for preventing damp and preserving the long-term health of the masonry.

 

Revealing Hidden Defects for Repair: Thick layers of grime or biological growth can disguise serious underlying issues like cracks, failed pointing, or structural faults. Cleaning the surface allows for an accurate condition survey, enabling you to identify and fix minor problems before they escalate into costly repairs.
