Energy efficiency is also a major driver due to the hot, humid climate.

Get answers to common questions about windows services in Sullivans Island, South Carolina.
The salt air, high humidity, and potential for strong winds and storms require windows with exceptional corrosion resistance and durability. We strongly recommend windows with aluminum or stainless-steel hardware, laminated glass for impact resistance, and finishes specifically rated for coastal environments to prevent premature deterioration. Ensuring your windows meet the Miami-Dade County High-Velocity Hurricane Zone (HVHZ) product approval standards, which are often adopted locally, is crucial for both performance and insurance compliance.
Yes, Sullivans Island has strict architectural and historical review guidelines, especially within the Old Village district. You will likely need a Certificate of Appropriateness from the Town's Board of Architectural Review (BAR) before obtaining a building permit. This process ensures replacements are consistent with the island's historic character, affecting window style, materials, and even color. Always verify requirements with the Town Hall, as non-compliant work can result in fines and required removal.
Costs are typically higher than inland due to the premium materials required for coastal durability and the specialized labor needed for historic homes. For a standard-sized home, a full replacement with hurricane-rated, low-E vinyl or fiberglass windows can range from $15,000 to $40,000+, while custom wood or clad-wood windows for historic properties can exceed $60,000. Always request detailed, itemized quotes that include removal, installation, trim work, and disposal.
The ideal windows are late fall through early spring (October to April), outside of peak hurricane season and the busy summer tourist and rental season. This period typically offers milder weather for installation and is less disruptive to your schedule or potential rental income. Scheduling well in advance is critical, as reputable local contractors often book up months ahead due to high demand for storm-related upgrades and renovations.
Prioritize contractors with extensive local experience who can provide references from other island homes. They must be thoroughly familiar with BAR permit processes, coastal building codes, and the installation techniques required for older home foundations. Verify they are licensed, insured, and offer strong warranties on both the product and their labor. A trustworthy installer will conduct a detailed initial assessment, discussing how to manage historical elements like original trim or dealing with potential rot from long-term moisture exposure.
