At a Glance
Adelaide sits somewhere between Melbourne's ornate heritage tradition and Perth's modern simplicity when it comes to cornice work. Character homes in Norwood, Unley, and Prospect have detailed Victorian cornices worth preserving. Newer homes in Mawson Lakes and Seaford use standard cove or square-set. Which end you fall on determines the cost more than anything else. The range is $150–$1,300 per job.
What's Included in the Price
- Supply of cornice in the specified profile (cove, ornate, or heritage match)
- Cutting, fitting, and fixing at the wall-ceiling junction
- Mitring internal and external corners
- Filling, sanding, and finishing all joins to a paint-ready surface per AS/NZS 2589 Gypsum Linings
Ceiling roses are priced separately per piece. Painting after installation is a separate scope. For replacement jobs, removing the old cornice and repairing the junction underneath is an additional line item.
What Affects the Cost
- Profile type. Simple cove is the baseline. Ornate Victorian profiles found in Adelaide's character homes cost more per metre to buy and install.
- Heritage matching. If you need to match existing cornice in a character home and the profile is no longer manufactured, custom moulding is required. Adelaide's character home density means this is a more common request than in Perth, though less frequent than in Melbourne.
- Square-set conversion. Removing cornice and finishing the junction to a clean right angle requires Level 5 plaster work. It is more labour-intensive than installing cove cornice.
- Number of rooms. Multiple rooms reduce the per-metre rate. A single room carries a minimum charge.
- Ceiling height. Character homes in Adelaide's inner suburbs often have ceilings above 2.7m, adding working-at-height time. Standard 2.4m in modern homes is more efficient.
- Old cornice removal. Pulling off old cornice reveals the junction beneath, which invariably needs repair before new cornice can go on.
Simple cove cornice in a single modern room sits toward $150. Ornate heritage cornice across multiple rooms in a character home, with custom profile matching, old cornice removal, ceiling roses, and high ceilings pushes toward $1,300.
Adelaide-Specific Considerations
Adelaide's character home belt creates genuine demand for heritage cornice work. Norwood, Unley, Prospect, North Adelaide, Goodwood, and Colonel Light Gardens all have a high concentration of Victorian and Edwardian homes with decorative plaster cornices and ceiling roses. These features are part of what makes the homes desirable, and homeowners generally want to preserve or restore them.
When renovating these homes, the common challenge is matching new cornice to existing. If you are restoring a water-damaged section of cornice in one room, or extending cornice into a new room that adjoins an original room, the profiles need to match. Adelaide has suppliers who stock a range of period profiles, and specialist plasterers who can make custom moulds. But it takes longer and costs more than off-the-shelf cove.
For homes in heritage conservation zones, cornice changes may require council approval. This is particularly relevant if you are considering removing ornate cornice and converting to square-set in a character home. The council may require retention of original plaster features as a condition of the heritage listing.
In newer suburbs (Mawson Lakes, Seaford, Craigburn Farm, Golden Grove), cornice work is standard. Cove cornice or square-set, modern profiles, standard ceiling heights. This is straightforward and competitively priced.
Adelaide has a smaller trade pool than Melbourne or Sydney, and specialist heritage cornice plasterers are a niche within that pool. If your project involves heritage matching, allow extra lead time to find the right tradesperson. For standard cove or square-set in a modern home, any competent plasterer can handle the work.
Hiring a Licensed Plasterer in SA
In South Australia, Consumer and Business Services (CBS) administers building work contractor licences. Plastering work that constitutes building work requires a Building Work Contractor's Licence.
When hiring:
- Verify the licence on the CBS licence search
- Ask to see completed cornice work, especially mitred corners
- For heritage matching, confirm experience with period profiles and custom moulding
- For square-set, confirm Level 5 finishing capability
- Get a written quote specifying profile, rooms, and whether removal is included
- Check public liability insurance
The quality of cornice installation shows at every corner. Take the time to find a plasterer who takes pride in their mitre work. It is the difference between a finished room that looks professional and one that looks rushed.
How We Calculate
Estimates are based on current plasterer rates in the Adelaide metropolitan area, adjusted for property age and typical cornice styles in SA. All prices include GST. Figures cover standard residential cornice installation. Heritage restoration with custom-moulded profiles may exceed these ranges.
