What To Check Before You Assume The Window Is Bad

Before replacing anything, look at when and where the condensation appears. Windows in bathrooms, kitchens, laundry rooms, and rooms with poor airflow tend to sweat first. North-facing glass and shaded rooms can also stay cooler and collect moisture more easily.
