Window Cleaning FAQs, answered by experts

Yes, pros are equipped to clean various glass types, including stained glass and skylights.

A professional cleaning service generally takes a few hours, typically between 2 to 4 hours, depending on the property's size and the severity of any stains. Keep in mind that wet cleaning methods will require additional drying time.

The best thing to clean windows with is a mixture of white vinegar, warm water, and dish soap. This will remove dirt, pollen, and grime without destroying any tints or protective films on your glass. You can also use a commercial window cleaner, but make sure to choose one that doesn’t have ammonia in it, as this can damage window coverings and frame materials over time.

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.

Clean regularly and inspect seals for wear. Replace damaged parts promptly to maintain effectiveness.
