Florida Building Envelope Maintenance

Coastal environments, like Florida, present unique challenges to the integrity of building envelopes due to persistent exposure to wind-driven rain, salt-laden air, ultraviolet radiation, and extreme weather events. These factors accelerate the deterioration of building materials and can compromise both structural integrity and interior living conditions. 

AtConstruction Solutions, Inc. (CSI), our field evaluations across numerous Florida coastal condominiums provide a foundation for identifying and implementing best practices in maintaining envelope performance and durability.

Background and Challenges

Building envelope systems in coastal zones must contend with:

• Salt corrosion: Metal components such as fasteners, railings, and flashing are prone to oxidation and decay.
• Moisture intrusion: Frequent and high-intensity rainfall paired with wind pressure increases the risk of water penetration.
• Thermal cycling: Fluctuating temperatures contribute to material expansion and contraction, leading to sealant failure and facade cracks.
• UV degradation: Continuous exposure to sunlight can break down exterior finishes and sealants.

Best Practices for Building Envelope Maintenance

1. Regular Visual and Infrared Inspections

• Conduct biannual assessments using infrared thermography to detect hidden moisture intrusion behind cladding systems.

2. Sealant Monitoring and Replacement

• Routinely evaluate joint sealants, particularly around fenestration and penetrations. Replace deteriorated or delaminated materials per ASTM C1193 guidelines.

3. Cladding and Coating Integrity

• Inspect stucco, EIFS, or siding systems for cracks, delamination, and efflorescence.
• Recoat surfaces with UV-stable, salt-resistant coatings as per the manufacturer’s maintenance schedule.

4. Balcony and Waterproofing System Reviews

• Verify that balcony membranes are continuous and properly flashed at transitions.
• Ensure positive drainage is maintained to prevent ponding, especially near guardrails and edge details.

5. Window and Door Systems

• Ensure fenestration units meet or exceed current Florida Building Code (FBC) impact and water resistance requirements.
• Evaluate glazing bead seals and perimeter flashing integrity per AAMA 502 standards.

6. Proactive Maintenance Documentation

• Maintain logs of all repairs, inspections, and component replacements to anticipate lifecycle needs and budget accordingly.

Recommendations

• Implement a comprehensive Florida building envelope maintenance plan tailored to your structure’s age and exposure level.
• Engage licensed engineers for evaluations following major weather events or prior to scheduled rehabilitation.
• Use only FBC-approved and coastal-rated products for any exterior system replacements or repairs.
• Include reserve funding specifically earmarked for facade and fenestration maintenance as part of the Structural Integrity Reserve Study (SIRS) requirements per SB 154.
