How to Spot Drafty Windows and Doors in Rock Hill SC

• Rattling panes or frames when the wind picks up
• Visible daylight around a closed door or window
• Weatherstripping that looks flattened, cracked, or missing
• A threshold that no longer touches evenly
• Peeling paint, staining, or soft spots around the trim

Those symptoms do not always point to the same repair, which is why a quick visual check matters.
