Certified and insured dry ice blasting professionals. EPA-, FDA-, and OSHA-compliant process
Never Abrasive, Always Precise
A dry ice blasting process built for surfaces that cannot be replaced.
Dry ice blasting without eroding original stone, plaster, or carved detail, even on centuries-old surfaces.
A Dry Process, Start to Finish
No water enters the material, so there is no risk of swelling, cracking, or mold in aged construction.
Landmark Compliant by Default
Every historic preservation project meets the standards required by preservation commissions, historic registers, and religious oversight bodies.
One Process, For Every Part of a Historic Restoration Project

Not Every Restoration Company is Equipped for Historic Restoration Work
With direct landmark commission experience, we coordinate directly with the NYC Landmarks Preservation Commission, State Historic Preservation Offices, and National Register requirements.
A controlled test pass on every job: pressure and technique are matched to the specific stone, plaster, bronze, or wood in front of us before full cleaning begins.
Respect for the material’s age: our goal is never to make an old building look new. We remove damage while keeping the texture and character that make it historic.
Full documentation on request. Every historic preservation project includes documentation that preservation architects and oversight bodies can reference.
Featured Project, Hispanic Society Museum and Library
Restoring El Cid at Audubon Terrace
The Hispanic Society Museum and Library is home to Anna Hyatt Huntington’s monumental bronze equestrian statue of El Cid Campeador, surrounded by four seated bronze warriors. Decades of oxidation and city grime had dulled the bronze surface across the entire ensemble.
Process highlights:
– Dry ice blasting of the main equestrian statue and all four flanking warrior figures.
– No abrasion to the original bronze patina or cast detail.
– No water or chemicals introduced near the surrounding limestone terrace.
The result: the statue and its four guardians returned to their original tone, with the bronze cleaned and every detail of the cast work left untouched.

FAQ
Do You Work on Landmarks Outside New York?
Yes. Our certified teams now travel across the continental United States for historic preservation projects, including designated landmarks, churches, and historic structures. Alaska and Hawaii are not currently included.
Will Dry Ice Blasting Damage Carvings or Delicate Stone?
No. The process does not abrade the surface, so carved details, plasterwork, and aged stone stay intact.
Do You Provide Documentation for Landmark Commissions?
Yes. Every historic preservation project includes documentation that preservation architects and oversight bodies can reference.
How Long Does a Historic Preservation Project Take?
Timelines depend on the size of the structure and the condition of the surface. Most quotes and a proposed schedule are ready within a business day of the site assessment.
