Window Cleaning FAQs, answered by experts

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.

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.

Clean the outside of your home at least once a year. If you live in an area with salty sea air, high levels of pollen, or an abundance of leaves in the fall, it's helpful to wash it at least two times a year. Frequent cleanings will allow you to remove debris and pests before they flourish into infestations, or cause mold and mildew.

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.

Window cleaning costs around $220, on average, but you could pay anywhere from $150 to $300 or more, depending on the number of windows, how accessible they are, and the type of windows. Some professional window cleaners charge on a per-window basis at around $10 per window, while others provide a single price for your entire home. Either way, more windows will mean higher cleaning costs. Picture windows tend to be the most affordable because they don’t require cleaning of internal components, while double-hung windows and skylights increase your price because they’re more complicated to clean and less accessible.
