Charleston doesn't get surprised by hurricane season โ it gets tested by it, every year, June through November with the worst usually August to October. The homes that come through with the smallest bills aren't lucky; they're prepared in specific, unglamorous ways. Here's the checklist we wish every Lowcountry homeowner ran each August, from a crew that spends every storm season pumping water out of the ones who didn't.
Know Your Water, Know Your Policy
This is the one that decides whether you're covered: homeowners insurance pays for water from above (wind-driven rain through damaged roof or windows). Flood insurance โ NFIP or private, a separate policy โ pays for water rising from below (storm surge, tidal flooding, overwhelmed drainage). Most Charleston flood claims are denied homeowner claims that were always flood claims. Check TODAY whether you carry flood coverage; there's a 30-day waiting period before NFIP policies take effect, so buying when a storm is named is too late.
The Outside: Where Storm Water Gets In
- Gutters and downspouts clear, extensions ON. A clogged gutter in a tropical downpour waterfalls straight down your siding and into the crawl space. Downspouts should discharge feet from the foundation, not at it.
- Walk your grading. After the next hard rain, watch where water pools. Anything standing against the foundation is a map of where storm water will enter.
- Roof and flashing check โ especially if your shingles are 10+ years old. Wind-driven rain exploits every lifted edge. One missing shingle is a ceiling stain; ten is a gutted bedroom.
- Garage door braced or rated. It's the largest opening in most homes and the most common structural failure point in high wind โ and once it goes, the house pressurizes.
The Inside: 30 Minutes That Save Thousands
- Photograph every room now โ walls, floors, contents, serial numbers on appliances. Pre-storm documentation is the strongest card you can hold in any claim.
- Know your shutoffs: water main and electrical panel. If water starts rising, power to affected circuits goes off before it arrives, not after.
- Elevate what you can't lose. Ground-floor and crawl-space storage: photos, documents, electronics go up a level or into lidded totes.
- Back up documents digitally โ insurance declarations, deed, inventory photos โ somewhere that isn't inside the house.
If Water Gets In Anyway
Storm water is never just water โ surge and floodwater carry contamination that changes how cleanup must be done (what a proper storm response involves, and why floodwater is treated as contaminated). The playbook: safety first, document everything, and get professional drying started within hours โ the full sequence is in our first-24-hours guide. In Charleston humidity, "we'll let it air out" is how a wet room becomes a mold remediation.
One more Lowcountry-specific step: after the yard drains, check the crawl space. It floods first and gets checked last โ we wrote a whole guide on what happens under raised homes.
Why We're Ready Before the Storm Is Named
Our crews monitor National Weather Service alerts for Charleston, Berkeley, and Dorchester counties around the clock during season โ when a flood watch goes up for your area, we're already staged for it. Locally owned on James Island, which means when the bridges are moving slow, we're already on the right side of them.
The Short Version
Verify your flood coverage this week (30-day wait!). Clear the gutters, walk the grading, brace the garage door. Photograph everything while it's dry. Save (843) 790-5769 in your phone now โ because the best time to know who you'll call is before the whole Lowcountry is calling at once.
