Professional Stonework Restoration
Preserving the beauty and structural integrity of your property’s stone facade requires a specialist approach. At C.L.E.A.N, we provide expert stonework restoration services for commercial, public and heritage buildings across London and the South East.
Common Issues Requiring Stonework Restoration
Pollution & Grime Build-Up
Urban pollution causes black staining and discolouration, especially on limestone, sandstone and Portland stone.
Weathering & Surface Erosion
Rain, frost and UV exposure can wear down stone surfaces, leading to pitting, cracks and gradual loss of detail.
Biological Growth
Algae, moss and lichen not only look unsightly — they trap moisture against the stone, accelerating damage.
Damaged Mortar & Joint Failures
Cracked or eroded mortar joints allow water ingress, leading to internal dampness, structural issues and further stone decay.
Spalling & Crumbling Stone
Freeze-thaw cycles and moisture penetration can cause surface flaking, requiring expert stone replacement or repairs.
