Heritage Brick Repairs — Sydney CBD
A heritage-listed Sydney CBD church with failing brickwork and repointing. Case study: matching period brick, lime mortar repointing, and facade restoration completed without disturbing services.
What was wrong when we arrived
A heritage-listed sandstone-and-brick church in the Sydney CBD had been letting water in for the better part of a decade. The original lime mortar between the bricks had worn away in sections, and modern cement-based repointing from a 1990s repair was trapping moisture inside the wall.
The parish committee had quotes from two larger heritage contractors who wanted to scaffold the entire facade and replace large sections of brick. Both quotes came in well over their restoration budget. They wanted someone who would only replace what was actually failing and match the period brick.
A heritage consultant was already involved on paperwork. They needed a builder who could read the spec, source matching brick, and not need their hand held through compliance.
How we fixed it
We scaffolded only the south and west elevations where the worst damage was. The north elevation had surface weathering but sound pointing, so it got a soft clean and a lime wash to bring the colour back.
The failing cement pointing was raked out by hand to a depth of 25mm. We never used an angle grinder on heritage brickwork — it shatters the arrises and leaves a tell-tale grey smear on the face of the brick that does not come off.
New bricks were sourced from a yard in Marrickville that still kiln-fires the old Sydney Common sizes. Three batches came in before we got one that matched the texture and firing colour of the originals. The parish committee kept the offcuts.
Repointing was done in three coats of lime putty mortar, hand-mixed on site with crushed Sydney sandstone aggregate. We deliberately stopped each day's work on a natural joint line so the curing was even and the colour bands did not show.
What the client got
The facade is now weathertight without trapping moisture. The parish committee has had two wet seasons since with no new ingress reported.
Heritage consultant signed off the work without a single rework request. We were asked back eighteen months later to quote on the bell tower.
The total came in at 38% under the larger contractors' quotes. Not because the work was cheaper — the materials were the same — but because we did not replace anything that did not need replacing.
Romans came in under budget and did the job properly. The other two contractors wanted to rebuild half the facade. Minas and the team only touched what needed touching, and you cannot see where the new brick goes into the old.

Questions about heritage brick repairs
How long does heritage brick repointing take on a church-sized facade?
For a single elevation on a typical Sydney CBD church, three to five weeks of working time. Two elevations running together takes five to seven weeks. We give a real timeframe in the quote, not a vague window.
Do you handle heritage approval paperwork?
We work with the heritage consultant you already have. We do not lodge DA or Section 60 applications ourselves, but we prepare the method statement, the mortar spec, and the brick sourcing notes the consultant needs to file.
What does heritage brick repointing cost per square metre?
It depends on the access, the height, and how much brick actually needs replacing. We price per elevation after we have looked at it. A ballpark for a single church elevation on easy scaffold access is $280 to $420 per square metre, materials and labour.
