Preservation
Is Stewardship.
Treat It That Way.
Historic buildings and stonework carry stories that can’t be replaced. We match the materials, replicate the techniques, and deliver the precision they deserve.
The Wrong Fabricator Can Do More Damage Than Time.
Restoration work is unforgiving. A stone that doesn’t match the original — in color, texture, or profile — is visible to everyone who knows what they’re looking at. A fabricator who doesn’t understand historical context can compromise a landmark that has survived centuries.
You’ve spent years building expertise in preservation. Your fabrication partner should bring the same level of care.
FABRICATION FOR LANDMARKS THAT MUST ENDURE
- Field Verification & Scanning - Our trained staff deploys some of the best 3D scanning equipment in the country to capture precise measurements and profiles directly on-site, before a single stone is cut.
- Historic Stone Matching - We source and match original stone with precision — color, texture, finish, and profile - for seamless integration with existing fabric.
- Hand Sketching & Clay Modeling - Our master carvers, drawing on the combined expertise of Quarra and Quarra Italia, work side-by-side with historic photographs to hand sketch and clay model profiles before fabrication begins - ensuring accuracy rooted in craft, not just technology.
- 3D Modeling & Historic Image Sourcing - We source archival photographs and documents, build detailed 3D models, and create stone mock-ups to establish a clear baseline expectation of quality before production starts.
- Replication of Historical Profiles - Complex moldings, carvings, and decorative elements reproduced using CNC technology and skilled hand finishing.
- Mock-Ups & Sample Fabrication - We produce physical samples from existing pieces for approval before full fabrication, with every step documented for landmark designation and project archives.
- Documentation & Archival Support - Detailed material and fabrication documentation for landmark designation requirements and project archives.
- Careful Logistics & Handling - We understand the sensitivity of restoration sites. Our delivery and installation coordination reflects that.
- Consultation from Day One - We engage early in the design process to identify stone sourcing risks and solve them before they become field problems.
WHY PRESERVATION SPECIALISTS TRUST QUARRA
- We've Worked on Buildings That Define American History - The National Cathedral is among the landmark projects we've been trusted to restore. We understand the gravity of that responsibility - and apply it to every preservation project we take on.
- End-to-End Process Mastery - From field scanning and historic image research to hand sketching, clay modeling, 3D modeling, mock-up approval, and final fabrication - we manage and document the entire process so nothing is left to chance.
- Master Carvers Across Two Continents - The combined expertise of Quarra and Quarra Italia means we have deep, generational knowledge of historical profiles - brought to life through hand skill alongside precision technology.
- Unmatched Stone Matching Capability - Color, texture, finish, veining, profile. We go further than any other fabricator to get it right, because in restoration work "close enough" isn't acceptable.
- CNC Precision Meets Hand Craftsmanship - For complex historical profiles and ornamental details, we combine CNC technology with skilled hand finishing to replicate what original craftsmen built.
- We Speak the Language of Preservation - Landmark designations, Secretary of the Interior Standards, archival documentation — we understand the regulatory and institutional environment you work in.
- A Partner Who Stays Engaged - Restoration projects are complex and evolving. We stay in the conversation from specification through punch list, not just through fabrication.
