Window Cleaning FAQs, answered by experts

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.

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.

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.

Clean with non-abrasive cleaners and a soft cloth, avoiding ammonia-based products that can degrade the film.

Yes, you can create a solution of dish soap and hot water to create a cleaning solution. You’ll want to mix about one to two drops of dish soap for every 8 ounces of hot water. If you use too much soap, it’ll create too many suds and make it harder to effectively wash away.
