"Our windows were in such bad shape that a simple cleaning wouldn't have made a difference. Rudy actually did a restoration on them by using a special compound and they now look amazing. The windows are crystal clear and look brand new. Rudy and Michael did a great job and were punctual and extremely courteous; the price was excellent. We can highly recommend this company."

Window Cleaning questions, answered by experts

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 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.

Smoke stains, grease buildup, mold, and water spots are common reasons for hiring professional cleaning services.

Finding a quality professional window cleaning service is much like finding any other vetted home pro: You should ask friends and family members who you trust for recommendations for window washers in your area and check online ratings. Reading a company’s reviews will give you a lot of insight into the service you can expect. Then, check their credentials and contact them to get a quote. Be sure to ask questions about their process and the products they use to get your windows to shine.

Professionals use advanced, eco-friendly products that ensure effective yet safe cleaning.
