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.

Reading a company’s reviews will give you a lot of insight into the service you can expect. Then, check their credentials and contact them to get a quote. Be sure to ask questions about their process and the products they use to get your windows to shine.

Generally speaking, you should clean your windows and any associated fixtures and treatments every six months. Otherwise, clean them as needed to keep everything running smoothly. If you live in a part of the country with especially hard water, you may have to clean them three or four times per year, and the same goes for areas where insects, pollen, dirt, and other debris can soil your windows and potentially cause issues with the moving parts.

Whether you tip before or after a carpet cleaning depends on when you’re available. If you’re home when they finish up, you can give them their tip after. However, if you need to leave before they’re done or if you won’t be home at all, you can prepare the tip beforehand and leave it for them in an envelope.
