Dirty windows can obscure sunlight, depriving houseplants of sustenance and forcing them to prop the fridge door open in a desperate attempt to photosynthesize from its tiny bulb. Keep domesticated vegetation from spoiling your milk with today’s Groupon: for $45, you get exterior window cleaning of up to 25 panes from AAA Window Cleaning and Janitorial Services (a $100 value). This Groupon is valid anywhere within the Las Vegas Valley, excluding Boulder City, and cannot be used for screens, french-pane windows, or storm windows.

AAA Window Cleaning and Janitorial Services’ experienced, insured handypeople meticulously and safely spruce up grimy windows. Crew members arrive at homes or businesses equipped with an arsenal of professional-grade gear, such as scaffolding and ladders that can reach upper-story windows. Occasionally, technicians may also enlist a tucker pole to unobtrusively reach across landscaping, vehicles, or intramural corporate volleyball championships blocking their targets. For an extra fee, AAA Window Cleaning and Janitorial Services can clean additional panes.
