Commercial Historic Restoration in Miami
Miami historic restoration with the experience and credentials a landmark property requires. Current work at the Vizcaya Museum & Gardens. assessment. Miami carries one of the densest concentrations of architecturally protected buildings in Florida: Vizcaya, the Freedom Tower, Miami Marine Stadium, Coral Gables Mediterranean revivals, Art Deco hotels on Ocean Drive, and historic estates throughout Coconut Grove and Brickell. Restoration on these buildings is not a generic masonry scope. It requires period-compatible materials, careful handling of original stonework, and direct coordination with the Miami-Dade Office of Historic Preservation, the City of Miami HEPB, or the relevant municipal preservation board.

Why Restoration Over Replacement
Why This Makes Sense For Miami Owners
Tap any reason to expand.
Restoration at the right stage of deterioration costs a fraction of structural failure and full replacement.
A spalling parking deck or cracked facade signals deferred maintenance before a tenant meeting begins. Restoration restores the building's professional character alongside its structural integrity.
Commercial valuations reflect maintenance history. Deferred concrete repair creates a documented liability that buyers and lenders price into any transaction.
Threshold buildings require recertification on strict schedules. Having the right licensed contractor in place before inspection reduces re-inspection cycles and delays.
On barrier island properties, unchecked chloride infiltration progresses from surface spalling to structural steel corrosion. Restoration stops that progression at whatever stage it is caught.
We provide the contractor's affidavit, material data sheets, and completion records the structural engineer of record needs to file with the building department.
Catch It Early
Six Signs Your Historic restoration Needs Attention
Chunks of concrete breaking from columns, beams, parking deck soffits, or balcony undersides indicate advanced corrosion pressure already at work.
Random intersecting cracks across a deck or facade panel suggest widespread deterioration of the concrete matrix that needs engineered assessment.
Orange or brown streaks beneath elevated decks or balconies confirm that reinforcing steel is actively corroding and expanding.
A section of parking deck or plaza that rings hollow has separated from the substrate. Under vehicle loads, this fails suddenly.
Rebar visible on columns, beams, or foundation walls indicates advanced deterioration that threatens structural capacity.
Open joints at window perimeters and expansion joints allow water into the envelope, driving facade staining, interior damage, and accelerated deterioration.

Technical Methods
How We Actually Do The Work
The details that separate a 30-year repair from one that fails next wet season. Click any method to see how it works in Miami conditions.
Spall Repair On Structural Elements
Commercial spall repair follows a more demanding sequence than residential because the affected elements often carry load and recertification inspections require documentation. Spalled sections are mapped, tested for delamination depth, and removed to clean, chloride-free concrete. Polymer-modified repair mortars are applied in correctly profiled lifts with full surface preparation and mechanical bonding profile.
Materials We Specify
Built For South Florida Exposure
A repair mortar that performs in a northern state may fail within a year in Miami. We specify based on the conditions each surface actually faces.
Polymer-Modified Repair Mortars
Bond strength, chloride resistance, and surface profile compatibility that commercial spall repairs require. Specified with the compressive strength, flexural bond, and chloride diffusion data engineering reports request.
Epoxy & Polyurethane Injection Resins
Epoxy for dormant structural cracks. Low-modulus polyurethane for active and water-transmitting cracks. Both specified with elongation and compressive data appropriate for the element type.
Traffic-Grade Waterproof Coatings
High-build traffic coatings with aggregate broadcast. Waterproofing, UV resistance, and slip-rated surfaces for parking decks, plazas, and pedestrian walkways.
Silane-Siloxane Penetrating Sealers
Prevent re-entry of chlorides into restored concrete elements. Specified at the appropriate silane content for the concrete porosity of the element being treated.
Jahn Restoration Mortars
Used on Mizner-influenced commercial facades, historic structures, and any building where the city's design standards require material compatibility with the original construction.
Our 6-Step Process
From First Call To Final Walkthrough
Every project follows the same disciplined sequence. No improvising, no shortcuts.
On-Site Assessment
We inspect every affected element, perform delamination mapping, depth testing, and substrate evaluation. For recertification properties, we review the engineer's deficiency report alongside our findings.
Written Scope And Fixed-Price Proposal
Written scope with a fixed price. For recertification scopes, includes material specs, mix designs, and methodology that the building department and the engineer of record require.
Pre-Construction Coordination
Coordinate with property managers, HOA boards, building engineers, and tenants. Phasing plans, parking deck traffic management, and tenant communication established before site mobilization.
Surface Preparation
All deteriorated and chloride-contaminated concrete removed to the correct depth before any repair material is introduced. The step that determines whether the repair holds for the life of the building.
Repair And Restoration
Repair mortars, injection resins, traffic coatings, waterproofing membranes, and sealers applied in correct sequence. We provide contractor's affidavit, material data sheets, and completion docs for recertification scopes.
Final Inspection And Documentation
We walk every restored element with the property manager before close-out. On recertification scopes, we provide the written completion documentation the engineer of record needs to file with the city.
The Honest Answer
Restoration Vs Replacement
Some contractors push replacement because it generates a larger contract. We do not. Here is the head-to-head.
Restoration
What we recommend in the majority of cases we assess in Miami.
Replacement
When the substrate is gone or the structure is past saving.
We give you a straight answer after the assessment, not after looking at the size of the contract.

Frequently Asked
Miami Historic Restoration FAQ
The questions Miami owners ask most. Tap any to expand.
Yes. Work on registered historic structures and properties within Miami's designated historic districts typically requires Certificate of Appropriateness review through the Miami-Dade Office of Historic Preservation, the City of Miami Historic and Environmental Preservation Board (HEPB), or the relevant municipal preservation board for cities like Coral Gables and Miami Beach. We provide the material specifications, methodology documentation, and salvage protocols those reviews require, and we coordinate scope phasing around the review timeline so site work begins on the approval date rather than after it.
Yes. We are currently working at the Vizcaya Museum & Gardens, a National Historic Landmark and one of the most significant Mediterranean revival estates in the United States. The full case study is at /historical/vizcaya-mansion. Beyond Vizcaya, our Miami portfolio includes Mediterranean revival estates in Coral Gables and Coconut Grove, Art Deco facade restoration in Miami Beach, and historic mansion and church restoration across Miami-Dade.
Original masonry on Miami historic buildings from the 1910s through 1930s was constructed using lime-based mortars, oolitic coral stone, and stucco mixes that behave fundamentally differently from modern Portland cement. Applying modern repair compound to these original materials damages the surrounding substrate by trapping moisture and creating a hardness mismatch that accelerates failure of the surviving original material. Jahn restoration mortars are formulated to match the strength, porosity, and weathering characteristics of the original masonry. The Jahn Applicator Certification is the credential that historic preservation boards specifically look for on the contractor of record.
Every historic stone removal scope we run begins with a written care, caution, and handling protocol. Existing stone units are documented before removal, labelled for salvage and possible reinstallation, and removed using methods chosen specifically for the existing condition: brittleness, prior deterioration, embedded anchoring, and substrate condition. Despite every reasonable effort, contractor cannot guarantee that certain stone units, edges, corners, or adjacent materials will not chip, crack, fracture, delaminate, or break during removal, handling, transportation, storage, or reinstallation. That risk is inherent to historic demolition and salvage work and is documented as such in our written scope so the owner understands exactly what the preservation reality is going in.
Landmark restoration including registered historic sites and properties on the National Register; Coral Gables and Coconut Grove Mediterranean revival estates; Miami Beach Art Deco facade restoration; church and cathedral preservation; mansion and estate stone, stucco, and masonry restoration; coral stone wall rebuilds; historic balcony and balustrade restoration; and ADA accessibility improvements on historic sites where stone removal, salvage, and reinstallation must be handled with preservation protocols. on-site assessment for any of the above.
