Heritage Building Restoration
Exterior and interior restoration that preserves significant masonry, stone, wood, metal, and architectural details while improving building performance.
Built around performance Details that matter
The finish is only as strong as the planning behind it.
Heritage restoration asks new work to respect old materials. Masonry, stone, mortar, wood, metal, windows, roofs, and decorative features respond differently to moisture, movement, salts, cleaning, and repair materials, so compatibility and documentation are central to the work.
Moderno's experience includes major exterior repair work at Osgoode Hall, delivered while preserving the building's historic components. We coordinate heritage consultants, mock-ups, probes, samples, skilled trades, protection, records, and carefully sequenced repairs.

Our scope Coordinated delivery
One team across the critical interfaces.
Mock-ups + samples
Establish approved mortar, stone, cleaning, coatings, profiles, tooling, colours, repair methods, and documentation standards.
Conservation repairs
Coordinate careful dismantling, retention, stabilization, repair, replacement in kind, replication, cleaning, and protection by qualified trades.
Integration
Resolve new flashings, drainage, structure, waterproofing, windows, services, and safety requirements without compromising significant fabric.
Our process Clear from the start
Decisions resolved before they become site problems.
- 01
Understand
Identify the building's significance, materials, deterioration mechanisms, owner priorities, approvals, and consultant requirements.
- 02
Prove the method
Complete probes, testing, samples, and mock-ups so the repair is compatible and its appearance is accepted before broad work.
- 03
Restore
Protect retained fabric, execute repairs in controlled areas, document discoveries, and adapt only through the approved review process.
- 04
Record + maintain
Complete inspections, final cleaning, photographic records, material information, maintenance guidance, and future monitoring recommendations.
Technical considerations No hidden handoffs
What we resolve with the project team.
- 01
Original materials, breathability, mortar strength, salt and moisture movement, cleaning sensitivity, repair visibility, and reversibility
- 02
Heritage approvals, consultant review, samples, mock-ups, skilled trades, salvaged material, profiles, tooling, and colour variation
- 03
Public protection, fragile fabric, vibration, temporary support, weather, access, archaeology, concealed conditions, and documentation
Frequently asked Practical answers
What property teams want to know.
How is heritage restoration different from standard repair?
The objective includes preserving cultural value and original fabric. Materials and methods must be compatible, significant details protected, and changes reviewed and documented through the appropriate heritage process.
Can modern waterproofing be added to a historic building?
Sometimes, but it must be carefully detailed so moisture is not trapped and significant materials are not damaged. The heritage and building-envelope consultants should guide the intervention.
What experience does Moderno have with heritage properties?
Moderno's project experience includes major exterior repairs at Osgoode Hall, where the work required careful preservation of historic building components.
