What Drives Moisture On Windows In Hot, Damp Weather

When the home is sealed tight but the humidity load stays high, the glass becomes the easy target for condensation.

The Damage Window Moisture Causes Over Time

Common steps include: Keep bathroom and kitchen exhaust fans running long enough to clear steam.

Run a dehumidifier when indoor air stays sticky, especially in shoulder seasons when the AC is not cycling as often.

Avoid blocking vents with furniture, drapes, or oversized blinds that trap cold air against the glass.

Sealing small leaks can make a noticeable difference, especially in older homes.

If the condensation is between panes, the cure is usually replacement of the insulated glass unit or the window itself.

If you are budgeting for replacement, how much does window replacement cost in Orangeburg SC depends on frame material, glass options, labor, and hidden repairs around the opening.

When Replacement Makes More Sense Than Repair
