Window Cleaning FAQs, answered by experts

Yes, you should plan on being home when a window cleaner is cleaning your windows. The professional will clean both sides of the glass and will likely disassemble parts of your windows from the inside to clean and inspect the inner components, including the balances and weatherstripping. Much of this work requires interior access to your home, which means someone will need to be home to provide access to the window cleaner.

Window cleaning depends on how the cleaning service defines their deep cleaning tasks, so pay attention to the details. You certainly should make sure window cleaning is included in the package. Some services will include it as an add-on, so you may have to pay extra. Find out if the cleaning includes interior windows only, or interior and exterior windows. Exterior windows may cost more.

Yes, using appropriate techniques and solutions for material-specific care.

Well water can leave ugly marks on your window. A vinegar-water spray will remove most well water stains from your windows. However, you can also use a baking soda paste if the stain is too stubborn. Consider applying waterproofing protection to the glass surface after cleaning for long-term protection. A protective film or spray layer also makes it easier to remove the water stains next time.

A standard professional cleaning of an entire apartment typically takes 2 to 3 hours. However, the timing varies depending on the size of the apartment, the number of people and pets that live in it, and how frequently it is cleaned. A deep cleaning typically takes 4 to 6 hours.
