Building a custom aluminum pergola is a significant property investment. Hiring an experienced contractor ensures a safe and compliant installation. Here are the key questions you should ask a pergola contractor before signing a contract.
1. "Are you a licensed and insured contractor in Florida?"
Installing permanent structural metal covers in Florida requires a valid license (such as a General Contractor, Specialty Structure, or Metal Finish license). Never hire an unlicensed contractor or pull owner-builder permits for work handled by a contractor. Additionally, verify they carry General Liability and Workers' Compensation insurance to protect your property from liabilities.
2. "Are your pergola systems engineered to meet Florida's wind loads?"
In South Florida's High-Velocity Hurricane Zones (HVHZ), structures must withstand high-speed winds. Ask if they provide signed, sealed structural calculations from a registered Florida Professional Engineer (PE). Installing a non-engineered kit that does not comply with wind load codes can lead to structural failure under storm pressures.
3. "Who handles the building permit submission process?"
Ensure the contractor's scope of work clearly defines who is responsible for drafting plans, submitting files to the building department, and scheduling inspections. If the contractor requests you to pull the permits yourself, this is a warning sign that they may lack proper licensing.
4. "What grade of powder coating is applied to the frame?"
South Florida's UV exposure and salt air will cause low-grade paints to bubble and peel. Verify that the aluminum frames receive an electrostatically applied powder coat finish meeting AAMA 2604 or AAMA 2605 standards to ensure long-term color retention and corrosion resistance.
Conclusion
Screening contractors by checking their licensing, verifying wind engineering compliance, clarifying permit responsibilities, and checking powder coat specifications ensures you select a professional partner to build a safe, durable outdoor structure.
