Salt air is part of the magic on Sunset Key, but it is also relentless on homes and equipment. If you own or plan to own here, you want effortless island living without surprise repairs or premature wear. This guide gives you a practical plan that protects your finishes, mechanical systems and landscaping while preserving long-term value. You will find recommended materials, a simple quarterly and annual schedule, and a concierge workflow for absentee owners. Let’s dive in.

Why salt air demands a plan

Sunset Key sits in a near-shore marine environment where salt spray, humidity and sun work together to accelerate corrosion and finish breakdown. Metals can pit, coatings chalk and blister, and wood weathers faster than it would inland. You also have seasonal risk during hurricane season from June 1 to November 30, when wind, rain and storm surge can deposit more salt and test seals. A proactive approach reduces avoidable damage and stretches the life of your materials.

Use the right materials on Sunset Key

Metals and fasteners

In exposed coastal locations, Type 316 or 316L stainless steel is the standard for exterior fasteners, railings, and hardware. Avoid 304 stainless on the exterior because it is more prone to corrosion in salt spray. Hot-dip galvanized steel can perform well for structural members, but the coating will age and needs inspection and maintenance. If you mix metals, isolate dissimilar ones with non-conductive washers to reduce galvanic corrosion. For docks or submerged fittings, choose marine-grade alloys and consider sacrificial anodes where appropriate.

Coatings, paints and sealants

Salt and UV speed up coating failure, so prep is everything. Remove corrosion before recoating and use the right primers for the substrate. On steel, an epoxy primer with a polyurethane or polysiloxane topcoat provides strong UV and abrasion resistance. On aluminum, use conversion coatings or primers made for aluminum. For stucco or masonry, breathable masonry paints are often preferable to avoid trapped moisture, though elastomeric coatings can bridge hairline cracks. Use marine-grade sealants at exterior joints and around fenestration, and replace any failing sealant promptly.

Wood, decking and exterior carpentry

Choose materials that hold up to salt, sun and moisture. Durable hardwoods like teak, ipe or cumaru, or marine-grade treated lumber, perform well. Composite decking can be an option if it is rated for coastal UV and moisture. Use 316 stainless fasteners and hidden systems where possible. Rinse surfaces with fresh water to remove salt, then maintain with appropriate oils or finishes per manufacturer guidance.

Windows, doors and glazing

Select fenestration built for coastal wind loads and impact protection. Look for corrosion-resistant hardware, coastal-rated finishes and tracks that can be cleaned and lubricated easily. Plan to re-seal perimeter joints on a schedule, and consider shutters or impact glazing for storm safety. Keep tracks clean of salt and sand to protect rollers and locks.

Roofing and flashing

Salt air can attack metal flashings and fasteners. Use corrosion-resistant flashings, such as stainless or properly coated metals, and corrosion-rated fasteners. Inspect the roof after storms and at least annually for sealant integrity, lifted flashing or early coating failure.

HVAC, pool and mechanical systems

Salt air is hard on coils, motors and enclosures. Position equipment away from direct spray where possible, choose units with corrosion protection, and schedule regular coil cleanings. Insulate and secure exposed piping. For pool systems, follow the manufacturer’s maintenance guidance, especially on salt-chlorine cells, metallic heaters and fittings.

A proactive maintenance schedule

Use this framework as a baseline. Adjust based on exposure, product warranties and contractor advice.

Quarterly checklist

• Fresh-water rinse of balconies, railings, stairs and decking. Focus on horizontal surfaces and handrails where salt settles.
• Visual check of fasteners and hardware for rust streaks, pitting or loosening.
• Quick inspection of sealants at windows, doors and roof penetrations for gaps or adhesion loss.
• Landscaping and irrigation check to clear salt crystals from nozzles and ensure proper operation.
• Replace or clean HVAC filters and verify condensate drainage.
• Pool equipment visual check, including salt system cells per manufacturer guidance.
• For absentee owners, capture dated photos of exterior surfaces, dock and gate areas for your maintenance log.

Biannual tasks: pre and post season

• Pre-hurricane season in May: secure loose exterior items, test shutters and impact protections, confirm insurance documents, and inspect roof, flashings and gutters.
• Post-hurricane season in December or after any storm: do a full exterior walk, document conditions, rinse heavy salt accumulation, and test irrigation and drainage.

Annual checklist

• Detailed metals inspection, removal of light corrosion and recoating where needed.
• Replace corroded fasteners with 316 stainless, and verify isolation where metals meet.
• Exterior paint touch-ups or recoats per product guidance; expect shorter cycles near the shoreline.
• Window and door service: deep clean frames and tracks, lubricate with marine-grade products, and replace weatherstripping and sealants.
• Deck maintenance: sand as needed, clean thoroughly and re-oil or re-stain; inspect fasteners and connections.
• Mechanical service: HVAC coil cleaning and corrosion check, outdoor electrical inspections and generator maintenance.
• Dock and seawall review for marine growth, fastener loss or spalling, and consult a marine contractor if repairs are needed.
• Pest and rot inspection for wood-destroying organisms and moisture issues under decks or in crawl spaces.
• Update your maintenance log with photos, invoices and contractor reports.

Post-storm actions within 24–72 hours

• Put safety first. Verify utilities and avoid standing water or downed lines.
• Rinse salt and debris from exterior surfaces with fresh water to slow corrosion.
• Photograph all damage for documentation.
• Prioritize urgent repairs: roof breaches, broken windows or doors, structural issues and compromised mechanical equipment.

Landscaping built for the Keys

A salt-tolerant landscape reduces replacement cycles and keeps the look cohesive with the island setting. Favor native or proven coastal species and place plants based on exposure. Options commonly used in the Lower Keys include sea grape, cocoplum and buttonwood for structure, with palms like sabal or silver thatch for height and movement. Choose groundcovers and grasses suited to sandy, saline conditions, and avoid species that need constant freshwater flushing.

For irrigation, use targeted systems such as drip for ornamentals and flush foliage and soils with fresh water after salt events. Improve drainage with organic matter and use slow-release fertilizers per local guidance. If you plan shoreline work, consult Monroe County rules for seawalls, living shorelines and mangrove management before you start.

Concierge and absentee oversight

If you are not on island full-time, a clear oversight plan keeps everything on track and catches issues early.

Visit cadence

• Monthly remote check: exterior walk, pool and systems verification with a photo report.
• Quarterly in-person inspection: complete the quarterly rinse and hardware checks, plus quick sealant review.
• Biannual professional services: HVAC, roof and flashing inspections, paint system assessment and pest inspection.
• Post-storm rapid response within 24 to 72 hours for safety checks, documentation and triage.

Concierge deliverables

• A standardized inspection report with timestamped photos and a condition summary.
• Action items with quotes from pre-approved contractors where possible.
• A cloud-based maintenance log for invoices, warranties and photos.
• A storm readiness checklist activated before June 1 and a post-storm protocol.

Escalation and contracting

• Pre-identify licensed coastal-experienced contractors in roofing, marine work, HVAC, painting and arbor care.
• Set authorization thresholds for emergency repairs and define what requires immediate owner approval.
• Maintain a recurring budget line for coastal maintenance items like coatings, metalwork and decking.

Documentation to keep

• Product data sheets for exterior coatings, fasteners and HVAC equipment.
• Manufacturer maintenance recommendations and warranty documents.
• A photographic baseline condition report for reference each season and after major weather events.

Budget and risk pointers

• Rinse often. Fresh-water rinses are one of the most cost-effective ways to slow corrosion.
• Standardize materials. Consistent metal alloys and fasteners reduce galvanic risk.
• Prioritize critical assemblies first: roof penetrations, window and door seals, railings and exterior mechanicals.
• Know the permitting rules. Work on docks, seawalls or within the high-water line typically requires permits, so plan timelines accordingly.
• Budget for coastal cycles. Expect more frequent painting, fastener replacement and finish restoration than inland.
