Expertise / Historic Preservation

Historic preservation.

Repairing what can be saved, replicating what cannot, and documenting the difference.

Preservation work rewards patience over speed. LoDuca Associates approaches a landmark building by first establishing what is original, what is later, and what is failing — because the cheapest repair is usually the one that keeps the original material.

Keep the fabric,
fix the failure

Historic structures fail for reasons modern buildings do not: trapped moisture, incompatible previous repairs, and materials that are no longer manufactured. We survey the existing conditions before pricing the work, so the scope reflects the building as it actually stands rather than as the drawings assume.

Where original material can be stabilized and reused, it is. Where it cannot, we replicate profile, species, and finish from surviving samples, and we document what was replaced. That record matters to landmark commissions, to grant administrators, and to whoever maintains the building next.

What we restore

Conditions Survey

Documented assessment of what is original, what is later work, and what is actively failing — before a scope is priced.

Envelope & Masonry

Repointing with compatible mortar, masonry repair, and moisture management that does not trap water in historic wall assemblies.

Windows & Millwork

Sash restored where the joinery survives, replicated to profile where it does not, with original glass retained where possible.

Structural Stabilization

Discreet reinforcement of framing, foundations, and roof structure that leaves visible historic fabric intact.

Systems Integration

Modern mechanical, electrical, fire protection, and accessibility routed to serve the building without scarring it.

Approvals & Documentation

Coordination with landmark commissions and preservation offices, with photographic records of conditions before, during, and after.

Four phases,
one standard

01
Survey
Existing conditions documented and the original fabric identified before anything is priced.
02
Specify
Repair methods and replacement materials selected for compatibility, then approved by the reviewing authority.
03
Restore
Careful, sequenced work by trades who have done it before, with conditions recorded as they are uncovered.
04
Document
Punch, commission, document what was repaired and what was replaced, and hand over.
