Window Cleaning FAQs, answered by experts

Use of harnesses and ladders ensures safe roof access.

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.

It depends on the company and the services it provides. If a cleaning company is just washing the outside of the windows, the pro may only wash the glass panes. But if they’re washing the inside and outside, they most likely bundle cleaning the sill and frame into the cost. It’s best to ask before you schedule a service to see if the company will charge additional fees.

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.

Window cleaning costs around $220, on average, but you could pay anywhere from $150 to $300 or more, depending on the number of windows, how accessible they are, and the type of windows. Some professional window cleaners charge on a per-window basis at around $10 per window, while others provide a single price for your entire home. Either way, more windows will mean higher cleaning costs. Picture windows tend to be the most affordable because they don’t require cleaning of internal components, while double-hung windows and skylights increase your price because they’re more complicated to clean and less accessible.
