Why Humidity Makes Window Problems Worse in Lexington SC

One foggy morning is not a crisis, but repeated condensation, sticking, swelling, or visible decay usually points to a larger issue. If the problem keeps returning after cleaning and caulking, the window is probably beyond a simple fix. That is where signs you need window replacement become difficult to dismiss, especially in older homes near the lake, along busier roads, or in rooms that take the full force of afternoon sun.
