Why rusted lintels crack brickwork
Look at the support behind the crack.
A lintel is the support that carries brickwork above a window or door. In older brick homes, steel lintels and arch bars can corrode. As the steel rusts and expands, it can lift or push the surrounding bricks out of line.
Where a rusted lintel is causing the damage, filling the crack or repointing over it will not repair the failed support. The steel needs assessment, with replacement and local rebuilding where required.

Signs worth checking
- Cracks at the cornersA stepped crack running up through the brick joints from the corner of a window or door.
- Brickwork out of lineBricks lifting or bulging over the opening, or a gap appearing between the frame and the wall above.
- Rust around the headRust staining or visible corrosion around the steel above the frame.
A crack alone does not confirm a failed lintel; the opening and the wall around it need assessing. If masonry is loose or visibly moving, keep clear and get prompt professional advice.
Our work · Hurlstone Park
Window and door heads, rebuilt.
We rebuilt the brickwork over a window and door, with new rendered heads. The photographs show the visible work around the openings.
Read the Hurlstone Park projectHow it’s done
Support first. Then rebuild.
A lintel carries the masonry over an opening. Replacing it means supporting that brickwork, then restoring the wall around the new steel.
Support the opening
The brickwork above is supported before anything is removed.
Remove the failed lintel
Bricks over the opening are taken down carefully so sound ones can be reused. The rusted steel is then removed.
New lintel
A new steel lintel is set in on proper bearings.
Rebuild and match
The brickwork goes back up and the joints are repointed or tuckpointed to match the wall.
What needs to be right around the repair
- The right support
The replacement needs to suit the opening, wall and exposure. The lintel size, bearings and temporary support are decided for the job; some openings need an engineer’s advice.
- Keeping water out
The flashing above the opening helps direct water away. Its condition is checked alongside the lintel so an existing moisture problem is not overlooked.
- The brickwork around it
Sound bricks are kept for reuse where possible. Damaged bricks, joints and any rendered heads are considered together so the repair suits the wall.
Typical prices
Plan the lintel replacement.
A site inspection assesses the support and the wall around it, then establishes what can stay and what needs replacing.

Will the window or door need replacing too?
Lintel replacement deals with the support and brickwork above the opening; it does not automatically mean a new window or door. Whether the existing frame can stay depends on its condition and the access needed for the repair. That is checked at the inspection.
Does the repair need a structural engineer?
The wall construction, opening width and cause of the movement determine what advice is needed. Larger openings or signs of wider structural movement may need an engineer’s assessment before the repair is planned. Photographs alone cannot determine the required lintel or temporary support.
Can the repaired brickwork match the wall?
Sound bricks are reused where possible, with replacement bricks selected to suit where needed. The mortar joints are repointed or tuckpointed to match the existing finish. Older materials vary, so an exact colour match cannot always be achieved; the options are discussed before work starts.
Why do quotes for the same wall differ, and how do I compare them?
Quotes can cover different work. One may rake out only the loosest mortar while another takes every joint back to a sound depth, and the mortar mix, how the finish is matched, access and scaffolding, and cleaning down all change the price. Compare quotes on the same area and finish, and ask each what is included and what is not. Any scaffolding your job needs is included in our quote.
How soon can you start, and how long will the work take?
We start as soon as we can once you accept the quote. As a guide, a small repair, a single lintel or most crack stitching takes a day or two, repointing a brick front fence one to two days, and tuckpointing a single-storey brick front about a week. Larger or higher walls, scaffolding and wet weather add time. Tell us about any renovation deadline when you enquire and your quote will give a realistic start date and duration.
Does a heritage-listed home need approval for brickwork repairs?
Check the listing and the proposed work before starting. For a local heritage item or conservation area, ask your council about approval or a maintenance exemption. State Heritage Register properties also have Heritage NSW requirements. Like-for-like work is not automatically exempt; the relevant conditions still need to be met.
