Chimneys are exposed to harsh weather conditions and are often one of the first areas of a home to deteriorate. Cracked mortar, loose bricks and water ingress can lead to safety issues if left unaddressed.
Grizzly Heritage provides professional chimney repairs across Sydney, restoring stability, weather resistance and appearance using appropriate materials and methods.
The crown, located at the top of the chimney, is designed to shed water and protect the masonry below. When it becomes cracked or deteriorated, water can seep in and cause damage to the flue, brickwork, and surrounding roof areas.
Our expert masons inspect and repair chimney crowns using modern and traditional techniques, applying new crowns or resurfacing existing ones with waterproof and flexible mortar mixes.

Chimney crown repair is the process of fixing or rebuilding the top surface of a chimney that protects the masonry structure from water ingress and weather damage. The chimney crown is a critical component that prevents rain, wind and debris from entering the chimney and causing deterioration of bricks, mortar and internal structure.
Over time, exposure to Sydney’s weather conditions can cause chimney crowns to crack, erode or separate from the chimney stack. When this occurs, water is able to penetrate deep into the masonry, leading to accelerated deterioration and moisture related damage.
Chimney crown repair restores this protective layer and helps extend the lifespan of the chimney and surrounding brickwork.
Chimney crown repairs should be considered if you notice:
If crown damage is left untreated, water can enter the chimney and masonry, causing internal damage and potentially leading to issues requiring brick repointing.
Many Sydney homes, particularly older and heritage properties, feature traditional brick chimneys that are constantly exposed to the elements. Over decades, original crown materials become brittle or cracked, allowing moisture to penetrate the structure.
Chimney crown repair on older homes requires an understanding of traditional materials and construction methods. Using incompatible hard cement repairs can cause further cracking and long term damage. A considered approach ensures repairs remain compatible with the existing masonry and perform effectively over time.
Each chimney crown repair begins with a thorough assessment of the crown, chimney stack and surrounding masonry. We identify the cause of failure and determine the most appropriate repair method.
Our process typically includes:
Correct slope and detailing are essential to ensure water drains away from the chimney rather than back into the brickwork.

Many chimney crown repairs fail because they rely on rigid cement materials that crack as the structure expands and contracts. Our approach focuses on compatibility and long term performance.
Our method includes:
This results in a chimney crown that performs reliably while respecting the character of the building.
