Surface condensation tends to gather where moisture is already highest, like bathrooms, kitchens, and laundry areas. In West Columbia and other humid parts of the state, shaded windows and cooler glass surfaces can collect moisture quickly even when the window itself is in decent shape.

If the fog is only on the inside surface, a few practical changes usually help. Run exhaust fans during and after showers, use the range hood when cooking, and keep HVAC filters clean so the system can move air properly. It also helps to maintain a steady indoor temperature instead of setting the thermostat too low during the day and then letting the house warm up at night.

If you are budgeting for replacement, ask for a detailed scope. Material, labor, glass type, and installation method all affect the final cost, and those variables can move the number more than homeowners expect.
