How to Weatherproof Windows for South Carolina Storms

South Carolina weather puts windows through a rough mix of heat, humidity, wind-driven rain, and sudden storm fronts. A window that looks fine on a calm day can leak, rattle, or fog up fast when a storm moves in.

A little preventive work before hurricane season or the peak storm months can save a lot of cleanup later. A thorough inspection looks at the whole opening, because air and water rarely enter through just one obvious spot.

The outside edge of the window is the first line of defense, and it deserves the closest look.

Do not smear new sealant over loose or failing material and expect it to hold. For larger gaps, backer rod may be needed before caulking, especially around older frames that have shifted with age.

A bigger architectural window can look great, but it also needs careful flashing and sealing to perform well.
