The answer to 'how long does window cleaning last' is that the duration of window cleaning can vary, but typically a professional window cleaning will last 6-12 months for most homes. The lifespan of window cleaning depends on factors like weather, climate, and how much dirt and debris accumulates on the windows. In drier, less humid climates, windows may stay cleaner for longer, while windows in coastal or industrial areas may need more frequent cleaning.
Regular window cleaning helps maintain the appearance and condition of your windows, and can also improve energy efficiency by allowing more natural light into your home. Many homeowners choose to have their windows professionally cleaned once or twice a year to keep them looking their best.
