Decorative elements are the signature flourishes that set heritage buildings apart — intricate plaster mouldings, hand-carved stone, wrought iron balustrades, and timber fretwork that showcase the craftsmanship of another era. Over time, these features often suffer from cracking, chipping, corrosion, or complete loss due to neglect, weather, or poor prior repairs.
At Atomic Projects, we approach decorative restoration as both an art and a science — balancing historical accuracy with the structural and material performance required for modern compliance.
Detailed Condition Assessment
Our process begins with a comprehensive inspection:
- Mapping Damage – Identifying cracks, spalling, corrosion, and missing sections.
- Material Identification – Determining original plaster mixes, stone types, timber species, or metal compositions.
- Historic Research – Reviewing archival photographs, drawings, and council heritage records to ensure exact replication.
Specialist Restoration Techniques
We employ specialist craftspeople trained in heritage work:
- Plaster & Moulding Restoration
- Hand-casting replacement sections using silicone or fibreglass moulds taken from surviving originals.
- Lime-based plasters matched for colour, texture, and composition.
- Stone & Masonry Detailing
- Carving and patching damaged stone with matching sandstone, marble, or granite.
- Using lime mortar pointing to maintain breathability and avoid material incompatibility.
- Timber Joinery & Fretwork
- Hand-turning balusters, fretwork, and trims in heritage timbers.
- Applying historically accurate stains, oils, and finishes.
- Metalwork & Iron Restoration
- Sandblasting and corrosion treatment of wrought iron and pressed metal.
- Recasting or fabricating decorative pieces using period-correct tooling.
Reproduction of Missing Features
When decorative elements are too damaged or missing entirely, we:
- Replicate from Surviving Examples – On-site or from similar period buildings.
- 3D Scan & Print Prototypes – To create exact replicas before hand-finishing.
- Integrate Discreetly – Blending new work seamlessly with existing finishes.
Finishing & Protection
- Application of heritage-accurate paints, gold leafing, or protective sealants.
- Discreet integration of modern coatings that resist UV, moisture, and pollutants without altering the visual authenticity.
- Final QA checks under varied lighting to ensure colour and texture consistency.
Compliance & Documentation
- Works follow Heritage Council and local planning authority guidelines.
- Preparation of before-and-after photographic records, method statements, and maintenance guides.
- Coordination with heritage architects and consultants for complex approvals.
Benefits of Decorative Restoration
- Preserves Cultural Value – Maintains the artistry and historical context of the building.
- Enhances Visual Impact – Restores the intricate detail that defines the property's character.
- Increases Asset Value – Heritage properties with intact decorative features command premium value.
- Protects Against Future Deterioration – Modern protective measures extend the life of restored works.

- Seamless Integration with Other Works – We coordinate decorative restoration alongside structural and façade repairs.
- Precision & Passion – Every detail is restored to honour its original craftsmanship.
Frequently Asked Questions
Can damaged plaster cornices be repaired rather than fully replaced?
Yes — in many cases, damaged sections of cornice can be carefully repaired rather than replaced in full. Where the cornice profile is intact on adjacent sections, we take silicone moulds of the surviving original to cast matching replacement sections. The new sections are then bonded and finished to blend seamlessly with the existing work. Full replacement is only recommended where the cornice is so extensively damaged that repair is uneconomical or structurally compromised.
What happens when a decorative feature is missing entirely?
Where decorative elements have been lost completely, we use a combination of archival research — historical photographs, council records, surviving examples on other sections of the building or similar period buildings — to establish what was originally present. We then prepare replicas using traditional crafting methods, supplemented by 3D scanning and prototype printing where complexity warrants. All replication work is documented for heritage records.
How do you treat wrought iron balustrades and metalwork that have corroded?
Corroded wrought iron is treated by removing loose corrosion with controlled abrasive blasting, then applying a zinc-rich primer to provide sacrificial corrosion protection. Where sections are too corroded to retain, we fabricate replacements using matching iron or steel profiles, powder-coated or painted to match the original finish. For complex decorative castings, we can produce replicas from surviving sections using traditional casting methods or CNC-machined moulds.
Do decorative restoration works require council heritage approval?
Like-for-like repair of decorative features — such as patching or casting replacement sections in the same material — is typically exempt from DA requirements. However, any change in material, finish, or profile may require approval. Works on State Heritage Register items almost always require notification or consent from the NSW Heritage Office. We advise on approval requirements for each element and prepare the necessary methodology statements and applications.
How long does decorative restoration typically take?
Duration depends heavily on the complexity and volume of decorative work. Simple cornice repairs may be completed in a few days per elevation. Complex metalwork fabrication, stone carving, or full moulding replacement across a large building can take several months. We provide a detailed programme and phased access plan as part of project delivery, and can often stage decorative works alongside other building restoration activities to minimise overall project duration.
