November is here, and for many absentee homeowners in the Coastal Empire and Lowcountry, it’s time to plan winter travels. To ensure your property is safe, a thorough coastal home winterization checklist is the most important tool you can have. Leaving a home vacant on the coast isn’t as simple as locking the door, and our mild climate can be deceptive.

Our mild climate is deceptive. A sudden cold snap, a forgotten appliance, or our year-round humidity can turn your pristine second home into a costly disaster zone.

Before you leave, walk through this essential coastal home winterization checklist. It’s designed specifically to combat the unique risks in Tybee, Savannah, and Hilton Head.

Check #1: The Pipe Perimeter (Preventing the $30,000 Flood)

The most common and costly mistake we see is underestimating our “mild” winters. All it takes is one night dropping below 30°F, compounded by coastal wind, to freeze and burst an uninsulated pipe in a crawlspace or attic.

Your Action Plan:

• Shut Off the Main Water: Locate your home’s main water shut-off valve. Turn it completely off.
• Drain Every Line: Once the main is off, open every faucet (hot and cold), shower, and tub in the house. Let them run until all water has drained.
• Flush All Toilets: Flush every toilet until the tank and bowl are empty.
• Don’t Forget These:
  • Disconnect and drain all outdoor hoses and spigots.
  • Shut off the water line to your icemaker and washing machine.
  • Ensure your crawlspace and attic pipes are properly insulated. A small investment in pipe foam can save you thousands.

Check #2: The Humidity War (Preventing Silent Mold Growth)

This is the “I didn’t think of that” problem specific to our coast. When you turn your A/C off for the winter, you also turn off your home’s primary dehumidifier.

In the damp, humid air of Tybee and Hilton Head, an empty, sealed house becomes a petri dish. Humidity spikes, and mold can bloom on drywall, in closets, and behind furniture.

Your Action Plan:

• Do NOT Turn the HVAC Off: Instead, set your thermostat to a “safe range.” We recommend setting the heat to 60-65°F. This provides a crucial buffer against sudden freezes and keeps air circulating.
• Use Dehumidifiers: If your home is prone to dampness, consider running a standalone dehumidifier with a hose attachment that drains directly into a sink. This is the single best way to control indoor humidity.
• Open Interior Doors: Prop open all interior doors, including closets and pantry doors. This allows air to circulate freely and prevents “micro-climates” where mold can start.

Check #3: The “Failed Check” (Protecting Your Insurance Policy)

Here is a fact many homeowners don’t discover until it’s too late:

Did you know many insurance policies contain a “Vacancy Clause”? If your home is empty for more than 30 consecutive days, your insurer could deny a claim for damage (like water damage from a burst pipe or vandalism) unless you can prove you had a system in place for routine checks.

A “Failed Check” is a silent financial risk.

Your Action Plan:

• Read Your Policy: Understand your insurer’s definition of “vacant” vs. “unoccupied” and what your responsibilities are.
• Create a Presence: Use simple light timers to give the home an “occupied” look.
• Stop Mail and Flyers: An overflowing mailbox or a pile of door hangers is a clear signal to thieves that the home is empty.
• Arrange for Checks: Ask a trusted neighbor or friend to walk the property’s exterior and interior once a week. They should be looking for obvious issues: signs of forced entry, water stains on the ceiling, or pest problems.
