Sandstone is the iconic Australian building stone — used extensively in heritage buildings in Sydney and Adelaide (Hawkesbury, Gosford sandstone). Bluestone (basalt) is common in Victoria and SA for heritage buildings and paving. Limestone is used in WA. Granite is used for benchtops and feature walls. Marble is used internally for high-end finishes. Reconstituted stone products offer a cost-effective alternative.

Repointing is the removal of deteriorated mortar from between masonry units (stone, brick) and replacement with fresh mortar. It's needed when mortar is crumbling, cracked, recessed more than 5–10mm, or missing — allowing water ingress. Heritage buildings require lime mortar repointing to match the original composition and allow the building to breathe — cement mortar traps moisture and accelerates deterioration.

Sandstone is porous and requires careful maintenance: clean with low-pressure water and soft brushes — never high-pressure washing which erodes the surface. Repair damaged mortar joints with compatible lime mortar. Avoid sealers that trap moisture inside the stone. Engage a stonemason experienced in heritage work for any significant repairs.

Natural stone is quarried directly from the earth and cut to size — each piece is unique. Reconstituted (cultured or cast) stone is made from crushed natural stone aggregate mixed with cement and pigments, poured into moulds. Reconstituted stone is 30–60% cheaper, dimensionally consistent, and lighter than natural stone — but lacks the unique texture and longevity of the real thing.
