Window Cleaning questions, answered by experts

Professional cleaning offers deeper sanitization, reaches grout inaccessible by home tools, and restores tiles without causing damage. Technicians have expertise and equipment that ensures long-lasting cleanliness and improved aesthetics.

Regular cleaning with non-abrasive cleaners helps prevent buildup and maintains clarity.

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.

Well water can leave ugly marks on your window. A vinegar-water spray will remove most well water stains from your windows. However, you can also use a baking soda paste if the stain is too stubborn. Consider applying waterproofing protection to the glass surface after cleaning for long-term protection. A protective film or spray layer also makes it easier to remove the water stains next time.

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.
