Coastal Home Considerations
Salt-Air Resistant Materials
Within 2 miles of Long Island Sound, use stainless steel fasteners, PVC/composite decking, marine-grade sealants, and corrosion-resistant hardware. Standard materials fail 30–50% faster in coastal environments.
Hurricane/Storm Preparedness
Building code requires wind-rated windows, proper flashing, and secure roof attachments. Insurance inspections increasingly check for coastal hardening measures.
Moisture Management
High humidity from ocean proximity demands continuous ventilation, proper vapor barriers, and mold-resistant materials in bathrooms and basements.
Military Family Priorities
- Fast turnaround: 4–8 weeks max for major projects
- Resale-focused: Neutral finishes, broad appeal
- Practical over luxury: Durable, low-maintenance choices
- Budget efficiency: Best value upgrades (kitchen, bath, flooring)
Seasonal Timing
Best for exteriors: May–October (warm, dry)
Best for interiors: Year-round, but fall/winter has more contractor availability
Avoid: January–February for foundation work (ground freezing)
Permit Requirements
Both Groton and Mystic require building permits for structural, electrical, and plumbing work. Coastal properties may need additional environmental permits for work within 100 feet of wetlands. E&S Construction handles all permit applications.
