Common Structural Issues Found in 30+ Year-Old Florida Condos

Florida is home to thousands of condominiums built in the 1970s and 1980s, many of which were constructed long before today’s building codes, material standards, and coastal resilience requirements. While these buildings were designed to last, decades of exposure to Florida’s harsh environment can take a toll. Understanding the most common structural issues in 30+ year-old Florida condos is the first step toward protecting safety, property value, and long-term performance.


1. Concrete Spalling and Reinforcing Steel Corrosion

One of the most frequently observed issues in aging coastal condos is concrete spalling, where pieces of concrete crack, flake, or fall away. This is often caused by corrosion of the embedded reinforcing steel (rebar), which expands as it rusts. 



2. Balcony and Walkway Deterioration

Balconies and elevated walkways are constantly exposed to rain, salt spray, and temperature changes. Over time, waterproofing systems fail, allowing moisture to penetrate the slab.


3. Water Intrusion and Failed Waterproofing

Roofs in coastal environments endure constant exposure to wind uplift, salt corrosion, and moisture intrusion. Without proper evaluation and engineering oversight, roofing systems may fail prematurely - leading to leaks, interior damage, and insurance challenges.


4. Roof and Drainage Deficiencies

Roof systems nearing or exceeding their service life are a major concern for older properties. Poor drainage, ponding water, failing flashing, and deteriorated mechanical stands can all contribute to leaks and structural deterioration.


5. Structural Cracking

Not all cracks are structural, but in older buildings, cracking can indicate movement, corrosion-related expansion, or long-term material fatigue.


6. Outdated Construction Details

Many older condos were built using construction practices that no longer meet modern standards. 


7. Deferred Maintenance

Years of postponed repairs, often due to budget constraints, can compound minor issues into major structural concerns.

PROJECT SPOTLIGHT

Location: St. Augustine Beach and Tennis Club

           

Scope of Work: Facility Rehabilitation  


The St. Augustine Beach and Tennis Club (SABTC) rehabilitation project was completed between August 2024 and August 2025 and followed a structured engineering and construction management process from start to finish. The project included condition assessments to define the scope of work, preparation of bid documents, contractor selection through a sealed bid process, and ongoing construction oversight. Regular site inspections were performed throughout the project to confirm compliance with the Florida Building Code (FBC) and project requirements.


Project Highlights

Concrete repairs were completed on balconies, elevated walkways, soffits, and vertical structural elements. All elevated walkways and balconies received upgraded waterproofing systems to improve durability and reduce the potential for future water intrusion. Keystone engineering maintained a consistent presence on site and performed inspections and reviews to confirm the repairs and coatings were completed in accordance with the project specifications.


The SABTC project reflects a coordinated engineering and restoration effort of the main building’s balconies and walkways and the townhome structures. This rehabilitation resulted in durable concrete repairs, improved waterproofing of walkways and balconies, and enhanced long-term performance throughout the property.
