"It went extremely well. They kept us up to speed on their arrival times. Eduardo and KC were courteous, professional, and did a great job on our windows. And, they came in at the lower end of the estimate. I will hire Smart Window Cleaning again."

Window Cleaning FAQs, answered by experts

To ensure the longevity and smooth functioning of new windows, regular maintenance is essential. This includes cleaning the glass and frames, inspecting seals for leaks or damage, and reapplying caulking as needed. It is also important to lubricate all moving parts and operating mechanisms to ensure they continue to operate smoothly.

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.

To maintain a glass shower door, clean it regularly with a non-abrasive cleaner to prevent soap scum and hard water stains. Using a squeegee after each use is also recommended. Additionally, periodically check for leaks and ensure all hardware remains secure to prevent long-term damage.

The best time to clean the outside of your house is during your outdoor spring cleaning. Wait until late spring, after the wave of pollen is done coating your home. You can also wash your house in late fall–before the first freeze–to remove leaves and branches from the gutters.

Luckily, glass block windows need minimal maintenance. Other than regular cleaning, the only maintenance involved in having a glass block window is inspecting for cracks every year and applying sealer to the mortar joints if the blocks are set in masonry mortar. Glass block windows hold up well against wind and moisture better than traditional windows and are not prone to rot.
