"Rudy and his team were great! Quoted me price, some windows required additional work but kept the agreed upon price. Rudy and the team arrived right on time and finished exactly when they estimated. Very nice and respectful crew, always important with kids in the house. Windows look like new! Highly recommend!"

Window Cleaning questions, answered by experts

Unless it’s written into the purchase agreement, there’s no legal obligation that a house you’ve bought has to be clean before you move in. The previous owner is generally required to sweep the house, but that doesn’t guarantee everything will be spotless upon your arrival. If possible, discuss the cleaning requirements with the real estate company before moving in.

For a standard 1,000-square-foot home, you should expect your window cleaner to take between 1 and 3 hours to clean all of your windows. Of course, the size of your home and the number and size of the windows you have will play a role in the timeline. Certain styles of windows—like picture windows, which have no moving parts—also take less time to clean.

The best homemade cleaning solution for windows is one gallon of warm, distilled or bottled water mixed with five to ten drops of liquid dish soap. This is what professional window cleaners typically use when they make their cleaning solutions. Using bottled or distilled water will help avoid hard water stains after cleaning, and the soap will cut through grease, smudges, and debris on your glass.

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.

The best way to clean outside windows is by using a garden hose. Start by spraying the windows with a high-pressure stream to clear off loose dirt and grime. Then use a mixture of hot water and dish soap and scrub the windows with a sponge. Rinse off the soapy water with the hose. Before you finish up, spray the windows with a solution of vinegar and water and wipe them down with a microfiber cloth.
