Charleston Hurricane-Season Home Maintenance: A Lowcountry Homeowner’s 2026 Checklist

Hurricane season runs from June 1 through November 30, and in the Lowcountry that window overlaps with our hottest, most humid, and rainiest stretch of the year. The encouraging news for 2026 is that NOAA is forecasting a below-normal Atlantic season — somewhere between 8 and 14 named storms, with 3 to 6 becoming hurricanes and 1 to 3 reaching major strength, as a developing El Niño tamps activity down. But “below-normal” is not “no risk.” It only takes one storm, or one stubborn king tide, to ruin a Charleston home that wasn’t ready. Here’s the maintenance checklist I give clients across Mount Pleasant, James Island, West Ashley, and downtown.

Start With Water: Drainage, Gutters, and King Tides

In Charleston, water is the threat long before wind shows up. Clean your gutters and downspouts, and clear leaves and debris from the storm drains nearest your property — a blocked drain turns an ordinary high tide into a flooded street. Speaking of tides, the National Weather Service flags minor flooding at the Charleston Harbor gauge around 7.0 feet, moderate at 7.5 feet, and major at 8.0 feet. King tides during full and new moons routinely push low-lying areas of the peninsula, the islands, and West Ashley into that range with no storm at all.

Two free tasks belong on every homeowner’s list: look up your property on the City’s floodplain maps, and confirm your hurricane evacuation zone at hurricane.sc. Knowing both before a storm is named saves you scrambling later.

Get Your Insurance in Order — Now, Not Later

This is the step people most often skip. A standard homeowner’s policy does not cover flood damage, including storm surge — that requires a separate flood insurance policy, and new flood coverage carries a 30-day waiting period before it takes effect. If you wait until a storm is in the forecast, you are already too late. Review your wind-and-hail deductible too (coastal policies often carry a separate, percentage-based hurricane deductible), and photograph or video every room and your belongings so a future claim goes smoothly.

Harden the Structure Before a Storm Threatens

Walk your property and look up. Trim tree limbs that overhang the roof or lean toward power lines, and clear dead branches that become projectiles in high wind. Inspect the roof for loose or lifting shingles and have them secured. Decide now how you’ll protect openings — installed hurricane shutters, or pre-cut plywood labeled and stored in the garage — because the weekend before landfall is when supplies vanish. Know where you’ll move patio furniture, grills, and planters, and make sure gates and sheds latch. Homes built after the 2005 code updates already include hurricane straps, impact-rated features, and elevated foundations in flood zones; if yours is older, ask a contractor about retrofits that pay off in both safety and insurance premiums.

Don’t Forget the Slow Disaster: Humidity and Termites

Storms grab the headlines, but Charleston’s everyday climate does quiet, expensive damage. Outdoor humidity hovers around 70 to 75 percent much of the year, so aim to keep indoor levels between 30 and 50 percent to hold off mold and wood rot. Service your HVAC system each season — it cools and dehumidifies — change filters regularly, and consider a dehumidifier or crawl space encapsulation if your home runs damp. Remember that salt air reaches well inland here and corrodes metal hardware and AC components, so rinse and inspect outdoor units. Finally, keep a termite bond current; coverage typically runs $300 to $600 a year and is far cheaper than the repairs Lowcountry termites can cause.

The Bottom Line

A below-average forecast is a gift, not a guarantee. The homeowners who sail through hurricane season are the ones who handled drainage, insurance, structure, and humidity before July — not during a watch. Spend a weekend on this list now and you’ll protect both your family and one of your largest investments.
