Window Cleaning questions, answered by experts

Most jobs take 2-8 hours, depending on the number of windows, height, and difficulty of access.

Whether you’re a renter or a buyer, you should clean a house when moving out. For renters, it’s usually written in the lease that a house must be cleaned before it’s vacated. If you’re unsure how thoroughly to clean the place, check with the landlord beforehand; otherwise, you may not receive your deposit back. When selling a house, a contractual agreement is often made with the realtor that the house is swept and that all personal belongings are removed before the previous owners move out.

Yes, professional window cleaners will clean the surface of the glass on both the inside and the outside. They will usually clean the tracks for your windows, check and clean the weatherstripping, and even disassemble parts of your window, if necessary, to clean and lubricate interior components and moving parts.

Soot can be harder to remove compared to other types of stains given its acidic nature. It can also cause underlying paint to peel off during the cleaning process. If your soot issue is a result of smoke damage, it’s recommended you call a pro to help remove it versus doing it yourself.

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.
