How to Prepare Your South Carolina Home for Hurricane Season

How to Prepare Your South Carolina Home for Hurricane Season

Hurricane season runs from June 1 through November 30, with peak activity in August through October. If you own property along South Carolina’s coast — from Little River down through Hilton Head — or even inland through the Midlands and Pee Dee region, hurricane preparation isn’t optional. It’s a recurring obligation that comes with the address.

South Carolina has been hit by 30+ hurricanes since 1851, including Category 4 Hugo in 1989, which caused $7 billion in damage. More recently, Hurricane Matthew (2016) and Hurricane Florence (2018) brought catastrophic inland flooding that affected areas 100+ miles from the coast. Even “minor” tropical storms regularly knock out power, topple trees, and cause localized flooding that damages unprepared homes.

This guide covers a practical, step-by-step approach to hurricane preparation that protects both your home and your family.

Phase 1: Before Hurricane Season (March–May)

The best time to prepare is before the season starts, when contractors are available and supplies are stocked.

Insurance Review

Critical: Standard homeowner’s insurance does NOT cover flood damage. Flood insurance must be purchased separately, and there’s a 30-day waiting period before a new policy takes effect. If you wait until a hurricane is approaching, it’s too late. Buy flood insurance now if you don’t have it. Even homes outside FEMA flood zones flood — Hurricane Florence proved this across the Pee Dee and Grand Strand regions.

Review your homeowner’s policy deductibles. Most SC coastal policies carry a separate hurricane or wind/hail deductible of 2–5% of the insured value. On a $400,000 home, that’s $8,000–$20,000 out of pocket before insurance pays. Know this number and have it available in savings. Our mortgage calculator can help you budget for insurance costs within your monthly payment.

Document Your Property

• Walk through every room and take photos/video of your home’s contents and condition. Store these in the cloud (Google Photos, iCloud, Dropbox) — not on a device that could be destroyed.
• Keep copies of insurance policies, mortgage documents, and property records in a waterproof safe or off-site location.
• Create a home inventory list with approximate values for insurance claim purposes. Several free apps (Encircle, Sortly) make this process straightforward.

Structural Preparation

Hurricane straps (also called hurricane clips or tie-downs) connect your roof trusses to the wall framing. In a hurricane, the roof is the first thing to go — and once the roof lifts, the walls follow. Homes built after 2000 in SC coastal counties likely have straps as code-required. Older homes often don’t. Adding them is one of the single most cost-effective hurricane preparations you can make. Some insurance companies offer premium discounts for verified hurricane strap installation. Find qualified contractors through our home services directory.

Generator Planning

Power outages after hurricanes can last days to weeks in SC. A standby generator ($5,000–$15,000 installed) provides automatic backup. A portable generator ($500–$2,000) powers essential circuits but requires manual setup and fuel management.

• Standby generator: Runs on natural gas or propane, starts automatically when power drops. Sized to power the whole house or critical circuits. Requires professional installation with a transfer switch.
• Portable generator: Runs on gasoline. Powers select items via extension cords or a manual transfer switch. Never run inside the house or garage — carbon monoxide kills.
• Fuel storage: Keep 15–20 gallons of fresh gasoline for portable generators. Treat with fuel stabilizer. Rotate stock every 3 months.

Phase 2: When a Storm Threatens (48–72 Hours Out)

When the National Hurricane Center issues a hurricane watch for your area (conditions possible within 48 hours), it’s time to activate your plan.

Secure Your Property

1. Install hurricane shutters or board windows. Pre-cut plywood (5/8″ minimum) should be measured, labeled, and stored for each window. Shutters (accordion, roll-down, or colonial style) deploy faster if pre-installed.
2. Bring in all outdoor items. Patio furniture, grills, potted plants, trash cans, children’s toys, bird feeders — anything that can become a projectile in 100+ mph winds. This includes decorations, hanging signs, and anything on exterior walls.
3. Secure the garage door. Garage doors are the weakest point in most homes. Use a bracing kit (horizontal bars) or deploy vertical braces if pre-installed.
4. Turn off propane tanks. Reduce risk of gas leaks from damaged lines.
5. Fill bathtubs with water. This provides non-drinking water for flushing toilets if water service is interrupted.
6. Charge all devices. Phones, tablets, battery packs, flashlights. Fill your car’s gas tank.

Pool and Spa Preparation

• Do NOT drain the pool — the weight of the water stabilizes the pool structure against groundwater pressure.
• Lower the water level 1–2 feet to allow room for rainfall.
• Remove all pool equipment, floats, and cleaning accessories.
• Turn off the pool pump and circuit breaker.
• Super-chlorinate (shock) the pool to prevent algae growth during the days without filtration.

Emergency Supply Kit

Phase 3: Evacuation Decision

South Carolina uses a zone-based evacuation system. Coastal counties are divided into zones (A, B, C in most areas), with Zone A being closest to the coast and first to evacuate. Know your zone — look it up at scemd.org.

• If ordered to evacuate: GO. Mandatory evacuations are issued when conditions are expected to be life-threatening. The governor authorizes lane reversals on major highways (I-26 becomes all-westbound from Charleston to Columbia) to facilitate evacuation.
• Plan your route in advance. The standard coastal evacuation routes are I-26 west, US-17 north/south, and US-501 west. Have alternate routes planned in case your primary is gridlocked.
• Know your destination. Hotel availability disappears within hours of evacuation orders. Have a pre-arranged plan — friend or family inland, a hotel reservation in Columbia or Greenville, or an established shelter location.
• Take pets. SC shelters increasingly accept pets, but space is limited. Most hotels along evacuation routes accept pets during declared emergencies. Never leave pets behind.

Phase 4: After the Storm

Returning Home Safely

• Wait for official clearance before returning. Downed power lines, flooded roads, and structural damage make immediate return dangerous.
• Document all damage with photos and video before touching anything — this is essential for insurance claims.
• Do not enter your home if you see structural damage, smell gas, or see standing water in contact with electrical systems.
• Contact your insurance company to file a claim within 24–48 hours of returning. Early filers get adjusters sooner.

Dealing with Flood Water

If your home flooded, the cleanup process is time-sensitive:

1. Remove standing water as quickly as possible (pumps, wet vacs, buckets).
2. Remove waterlogged drywall, insulation, and carpet. Cut drywall at least 12 inches above the water line.
3. Treat all surfaces with antimicrobial solution. Mold can begin growing within 24–48 hours in SC’s humidity.
4. Run dehumidifiers and fans continuously. Open windows if weather permits.
5. Document everything for your flood insurance claim — keep receipts for all cleanup expenses.

Contractor Scam Prevention

After every major storm, unlicensed contractors descend on affected areas. Protect yourself:

• Verify SC contractor licenses at llr.sc.gov before signing anything.
• Never pay more than 30% upfront for any repair work.
• Get written contracts with detailed scope of work, timeline, and payment schedule.
• Don’t sign an Assignment of Benefits (AOB) that gives a contractor control of your insurance claim.
• Get multiple estimates — don’t accept the first door-to-door offer.

Hurricane Preparation Cost Summary

First-year hurricane preparation for a coastal SC home runs $5,000–$25,000 depending on the level of hardening you choose. Impact windows and a standby generator represent the high end but also provide the most protection and the biggest insurance premium discounts. Budget for these investments using our HELOC calculator if needed, and factor the annual costs into your homeownership budget with the maintenance calculator.

Pet Safety During Hurricanes

Pets are part of the evacuation plan, not an afterthought. South Carolina learned this lesson during Hurricane Floyd in 1999, when many residents refused to evacuate because they couldn’t take their animals. Since then, SC shelters and evacuation protocols have improved for pet owners, but planning ahead is still essential:

• Identify pet-friendly shelters. Not all emergency shelters accept animals. SC county emergency management offices maintain lists of pet-friendly shelters and their specific requirements (crate, vaccination records, food). Check scemd.org for your county’s pet shelter locations.
• Keep a pet emergency kit. Include 7 days of food and water, medications, vaccination records, a carrier or crate, leash, waste bags, and a recent photo of each pet (for identification if separated).
• Microchip and ID tags. If your pet doesn’t have a microchip, get one before hurricane season ($25–$50 at most vets). Ensure your contact information is current in the microchip registry. Collar tags should include your phone number and a backup contact number.
• Hotel reservations. Many hotels along SC evacuation routes accept pets during declared emergencies even if they normally don’t. However, availability disappears quickly once evacuations begin. Book pet-friendly hotels in Columbia, Greenville, or Charlotte as soon as a hurricane watch is issued.
• Never leave pets behind. SC law does not currently classify leaving pets during a mandatory evacuation as animal cruelty (unlike some states), but animal rescue groups document that pets left behind face high mortality rates during major storms. If you evacuate, your pets go with you.

Frequently Asked Questions

When is hurricane season in South Carolina?

Officially June 1 through November 30, with peak activity from mid-August through mid-October. The earliest recorded hurricane impact on SC was in June, and the latest was in November. Preparation should begin in spring (March–May) when contractors are available and supplies are in stock. Don’t wait until a storm is forecast.

Do I need flood insurance if I’m not in a flood zone?

You’re not required to carry flood insurance outside FEMA-designated high-risk zones, but it’s strongly recommended in South Carolina. Over 25% of all flood insurance claims nationally come from properties outside high-risk zones. Hurricane Florence flooded areas in the Pee Dee region that had never flooded before. Policies for Zone X (low-risk) properties cost significantly less — often $400–$800/year — making them a worthwhile investment.

How much does hurricane insurance cost in SC?

There’s no single “hurricane insurance” product. Hurricane coverage comes from two sources: your homeowner’s policy (covers wind and rain damage entering from above) and flood insurance (covers rising water). Homeowner’s insurance in coastal SC averages $2,200/year with separate hurricane/wind deductibles of 2–5%. Flood insurance runs $1,200–$4,500/year in high-risk zones. Combined, expect $3,400–$6,700+ annually for full hurricane protection on a coastal home.

Should I evacuate for a Category 1 hurricane?

Follow official evacuation orders from the governor’s office and your county emergency management. Category 1 storms (74–95 mph winds) can still cause significant damage, particularly from storm surge and flooding. If you’re in Evacuation Zone A (closest to the coast), you should evacuate for any hurricane. Zones B and C typically evacuate for Category 2+ storms. Always err on the side of caution — your home can be repaired or rebuilt; you can’t.

What’s the most cost-effective hurricane upgrade for my home?

Hurricane straps/clips connecting the roof to the wall framing offer the highest return on investment. At $1,500–$3,500 installed, they prevent the most catastrophic failure mode (roof lifting off the walls) and may qualify for insurance premium discounts. After straps, impact-rated garage door bracing ($200–$600) addresses the second-most-common point of failure. These two upgrades together cost under $4,000 and dramatically improve your home’s survivability. Visit our home buying guide for more on protecting your SC property investment.

Can I get an insurance discount for hurricane upgrades?

Yes. Many SC insurers offer premium reductions for verified wind mitigation features. Hurricane straps, impact-rated windows or shutters, secondary water barriers on the roof, and reinforced garage doors can each earn discounts. A wind mitigation inspection ($75–$150) documents these features for your insurer. Combined discounts can reach 15–30% off your wind premium, which on a $2,200/year coastal policy saves $330–$660 annually. The inspection cost pays for itself in the first year, and the savings continue for the life of the policy. Ask your insurance agent about available wind mitigation credits before and after making upgrades.

How do I prepare my crawl space for a hurricane?

Crawl space flooding is a common issue during hurricanes and heavy rain events in SC. Before hurricane season, ensure your crawl space has functioning drainage, the sump pump works (test it and install a battery backup), and any encapsulation system is intact. Seal crawl space vents if your system is designed for sealed operation, or open them to allow water to flow through if your system relies on ventilation. After any flooding event, dry the crawl space within 24–48 hours to prevent mold growth — SC’s humidity will support mold colonization rapidly if moisture lingers. Run dehumidifiers continuously until the space reaches below 55% relative humidity.
