"Kirk arrived right away and gave me a bid on cleaning my gutters. I hired Kirk and he showed up as planned and did a stellar job! The bid was very reasonable and he completed the job very quickly. I would highly recommend Kirk and his employees! George B. in Missoula"

Window Cleaning questions, answered by experts

The most likely cause of smearing or streaking after cleaning your windows is residue left on the glass from the cleaner you’re using. Consider diluting the solution and cleaning them again, or use old newspaper to dry the windows after cleaning, as this will soak up any residual material. Additionally, aim to clean your windows on a cool, cloudy day, as cleaners will dry more quickly on the glass if it’s hot and sunny, promoting streaking.

A professional cleaning service generally takes a few hours, typically between 2 to 4 hours, depending on the property's size and the severity of any stains. Keep in mind that wet cleaning methods will require additional drying time.

To clean an estate, start by locating all important documents, which you’ll need to sort through. Have the mail forwarded, change the locks, and take inventory of the entire estate. Once you know what you’re dealing with, create a plan and a timeline for the cleanout. Start clearing out rooms and sorting items to donate, sell, or get rid of. Finally, deep clean the property.

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.

Time varies by number and size of windows but usually 2-4 hours.
