Sandstone is a natural, breathable material commonly found on heritage buildings across Sydney. Over time, weather exposure, moisture and previous incorrect repairs can cause sandstone to deteriorate, crack or delaminate.
Grizzly Heritage provides specialist sandstone restoration using compatible materials and proven conservation techniques to stabilise, repair and preserve original stonework.
Our sandstone repointing services involve removing failing mortar joints and replacing them with MXL-enhanced mortar that matches the original colour and texture. This helps maintain the historical authenticity and longevity of the structure.
"Sydney’s coastal salt spray accelerates sandstone erosion. Our breathable lime mortar prevents trapped moisture. Critical for heritage and modern buildings."
We work on a wide range of sandstone features including walls, fences, retaining walls, chimneys, and foundations. Our techniques are suitable for both residential and commercial properties, as well as heritage-listed buildings.

Sandstone is porous and needs breathable lime-based mortar to prevent moisture being trapped inside, which causes damage.
Yes, our team custom matches mortar blends for a seamless and heritage-respectful look.
Yes, our methods and materials meet NSW heritage conservation standards.
We work on sandstone fences, walls, retaining walls, chimneys, buildings, and foundations.
Yes. Sandstone is softer and more porous than brick, requiring different mortar composition and gentler techniques to avoid damage.

Sandstone repointing is the process of carefully removing deteriorated mortar from between sandstone blocks and replacing it with a compatible mortar designed to protect the stone while allowing natural moisture movement. Unlike brickwork, sandstone is a softer and more porous material that requires a specialised approach to avoid damage.
Over time, mortar joints in sandstone walls can erode due to weather exposure, moisture ingress and natural building movement. When mortar fails, water is able to penetrate behind the stone, leading to staining, surface decay and long term structural issues. Sandstone repointing restores joint integrity and protects the stone without altering its appearance.
Correct repointing plays a critical role in preserving the lifespan and character of sandstone buildings.
Common issues include surface erosion, cracking, spalling, salt damage and failed patch repairs. Using incompatible materials or hard cement products can accelerate deterioration rather than prevent it.
Every sandstone project is assessed individually. Our work may include careful cleaning, stabilisation, crack repair, patching and repointing using materials selected to match the existing stone and allow the masonry to breathe.
Sandstone repointing may be necessary if you notice:
If mortar deterioration is left untreated, moisture can become trapped within the sandstone, leading to irreversible damage that is far more costly to repair.
Sydney has a large number of historic buildings constructed from sandstone, including terraces, churches, civic buildings and retaining walls. Many of these structures were built using lime based mortars that are significantly softer and more breathable than modern cement mixes.
Using hard cement mortar on sandstone is one of the most common causes of stone damage. Cement restricts moisture movement and forces water into the sandstone itself, leading to spalling, cracking and surface loss. Heritage sandstone repointing requires careful material selection to ensure compatibility with the original construction.
Our approach respects the age, exposure and historical value of sandstone buildings while providing long term protection.
Each sandstone repointing project begins with a detailed assessment of the existing mortar, stone condition and environmental exposure. We determine the appropriate mortar composition and joint profile before any work begins.
Our process includes:
Every stage of the process is designed to protect the sandstone while restoring the performance of the joints.

Sandstone requires a more considered approach than standard masonry work. We do not use generic mortar mixes or aggressive removal methods. Many sandstone buildings are heritage listed or located within conservation areas. We understand the importance of using compatible materials and methods that respect original construction and local council requirements.
Our sandstone repointing work includes:
This approach reduces the risk of stone damage and extends the life of the structure.
