Why Sandstone Costs More in Sydney

Sandstone commands a premium because of the material cost (quality Hawkesbury sandstone blocks are heavy and expensive to quarry and transport), the skilled labour required (experienced stonemasons charge more than general wall builders), and the longer installation time compared to sleeper or block systems.

However, sandstone offers exceptional value over its lifespan. A well-built sandstone wall lasts 100+ years with virtually no maintenance. It also adds significant street appeal and property value, particularly in Sydney's premium suburbs where sandstone is a heritage feature.
