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.

Luckily, glass block windows need minimal maintenance. Other than regular cleaning, the only maintenance involved in having a glass block window is inspecting for cracks every year and applying sealer to the mortar joints if the blocks are set in masonry mortar. Glass block windows hold up well against wind and moisture better than traditional windows and are not prone to rot.

Yes, but professionals use specialized equipment and cleaning solutions to safely achieve streak-free, long-lasting results.

Clean high-traffic areas such as kitchen surfaces, bathroom surfaces, and bedding once per week. Deep clean other areas every three months to a year. How you use a space can help you figure out how often it should be cleaned, with areas where eating, bathing, and food prep occur getting the most frequent attention.

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.
