How do I stop water from forming on the inside of windows?

Bonnie, I have aluminum windows, too, and this is a perpetual problem. The aluminum is a thermal bridge which wicks the heat out of the house. The best solution is to put a storm window on the inside of the house that covers the window casing. The cheapest way to solve this is to use window shrink wrap attached to the window trim. For a more permanent solution, make or have made storm windows that attach to the trim.

Use a window insulator kit. It blocks warmer/humid indoor air from reaching the cold glass and fogging/condensing.

Or use a dehumidifier. The unit will remove moisture from the air.

The more you plants have, the more humidity. Every time you water them, you’re creating a source of moisture.

Make sure your dryer vent is well sealed and vents to the outdoors.

Cover up fish tanks with cheesecloth to reduce evaporation.

Place small portable heaters below the offending window.

Use the window kits on the inside windows. They create a thermal break from warm room air hitting the cold aluminum windows. Also keeps the heat in the home and cold out.

Thank you everyone for the help!
