Sandstone Cleaning Double Bay | Walls, Thresholds & Heritage Detail

Specialist sandstone cleaning for Double Bay's boundary walls, thresholds and heritage stonework — chemically treated, never blasted.

Double Bay’s sandstone — boundary walls in the streets rising toward Bellevue Hill, terrace thresholds and sills, gate posts and garden stairs — sits in exactly the conditions blackening biofilm loves: plane-tree shade, harbour damp and little drying wind. The growth lives inside the stone’s pores, so a surface blast regrows darker within a season after permanently cutting the block’s face.

What’s included

Biocide treatment through the pore structure with proper dwell time, low-pressure rinsing that carries the dead growth away without touching the face, lime-mortar joints protected, heritage tooling and carved detail hand-worked — much of the area sits within Woollahra conservation streets and gets treated to that standard — and honest advice on selective breathable sealing.
