Hurricane Season Water Damage Prevention in South Carolina

A named storm brings three separate water problems to a South Carolina home. The first is rain driven against the envelope, finding any gap in a roof, window or vent. The second is surface water that overwhelms drainage and pools against the foundation. The third is flooding, from surge on the coast or from rivers and creeks that rise days after the rain has moved on.

Wind gets the attention, but water causes the lasting damage. Insurers see far more water claims than structural wind claims after most storms, and the work below is aimed at that.

Start With the Water That Leaves the Roof

Gutters and downspouts move hundreds of gallons off a roof during a heavy system, and they only work when they are clear. Clogged gutters send water over the edge, where it lands in a narrow band along the foundation and soaks the soil next to the wall. That is how seepage through block foundations begins.

Clear debris from the roof and gutters before the season, then check again in late summer after pollen and spring growth. Look for gutters that sag or pull away from the fascia, because the fasteners loosen over time and a sagging section spills water against the house.

Downspouts matter as much as the gutters. If a downspout discharges within a foot or two of the foundation, the water ends up exactly where you do not want it. Add extensions or splash blocks so the discharge point is several feet away, ideally at a slope that carries water toward the yard rather than back toward the wall.

Look at How the Yard Drains

The ground around a house should slope away from the foundation on every side. Over years, mulch beds build up against the wall, soil settles, and the slope reverses without anyone noticing. Add a few inches of soil near the foundation to restore the fall if you find a low spot holding water.

Walk the property after a normal rain, not after a storm, and watch where water stands. Low spots in a yard are where it will pool during a heavy system, and if those spots sit against the house or over a septic drain field, that is a problem worth correcting before hurricane season rather than during it.

If your home has a French drain or a yard drain system, check that the outlets are clear and that water actually exits. A drain that has silted in looks fine from above and does nothing during a storm.

Check the Envelope: Roof, Windows and Vents

Wind-driven rain enters through small openings, so the goal is to close them. Look for lifted or missing shingles, cracked flashing around chimneys and vent pipes, and deteriorated sealant around roof penetrations. A roof that is within a few years of replacement is worth evaluating before a storm rather than after.

Windows and doors should seal when closed. Worn weatherstripping and deteriorated exterior caulk allow water to reach the interior during a long, wind-driven rain. Check the weep holes in sliding doors and windows to make sure they are open, since water that cannot drain through them finds its way inside.

Exterior vents, dryer vents, bath fan terminations and outdoor outlet covers are all common entry points. A missing vent cover or a broken outlet gasket is a small repair that prevents an interior wall from soaking.

Below-Grade Spaces Need the Most Attention

If your home has a crawlspace, a basement or a below-grade room, this is where storm water does the most damage and where prevention pays the most. Check that the vapor barrier is intact and that soil is not sitting against wood framing. Standing water in a crawlspace during a storm can soak floor framing in a day.

Test the sump pump before the season. Pour water into the pit and confirm the pump kicks on and moves water out. Check that the discharge line is clear, connected and pointed away from the foundation, since a discharge that runs back along the wall simply recirculates the water. If the pump is old or if the home loses power often, a battery backup is worth considering.

Clear the area in front of any floor drain and keep stored items off the floor on shelving. When water does arrive, items on the floor become saturated material that has to be discarded, and a blocked drain turns a minor event into a flooded room.

Insurance and Documentation Before the Storm

Flood damage from rising water, storm surge and surface water is generally not covered by a standard homeowners policy. It requires a separate flood insurance policy, and those policies typically have a waiting period of about thirty days before coverage begins. That means the decision has to be made well before a storm has a name, not when a track is projected toward the coast.

Sewer and drain backup coverage is a separate endorsement on many policies, and it often carries a limit below the cost of a real loss. Read your declarations page now and note both the endorsement and its cap.

Take photographs or a slow video walkthrough of every room, closet, appliance and finished surface while everything is undamaged. Store those files somewhere other than the house. After a storm, adjusters compare damage to a baseline, and homeowners who have a pre-storm record have a much easier time with claims, especially for items like flooring and cabinetry.

Prepare an Emergency Kit and a Communication Plan

Keep a written list of the phone numbers you would need, including a restoration dispatch line, an electrician and a plumber. After a widespread storm, internet and cellular data may be unreliable, so a paper list is more dependable than a phone that cannot load a contact.

Store towels, a wet-dry vacuum, plastic sheeting, tarps, work gloves and a few large trash bags where you can reach them without wading. If a window or door seal fails during the storm, tarps and sheeting limit how much water enters.

Have a plan for where you will go if the house becomes uninhabitable, and know how to shut off the power, the water and the gas. During a storm, the ability to shut off a supply line in the first minute is often the difference between a wet patch and a flooded floor.

• Gutters cleared, downspouts discharging well away from the house
• Ground graded to slope away from the foundation
• Roof flashing, shingles, vents and window seals inspected
• Sump pump tested and discharge line confirmed clear
• Vapor barrier and crawlspace checked before the season
• Flood policy in place well ahead of the waiting period
• Photos of every room taken and stored off-site
• Emergency supplies and a paper phone list ready
