Window Genie’s scum-busters arrive to each job in a clearly marked chariot armed with the necessary equipment to tackle exterior household dust and decay. Pane pamperers kick off a window cleaning for homes up to two stories by scraping off tree sap, bird droppings, and other hard-to-clean debris with a specially designed blade that moonlights as a shiv stunt double in prison movies. Then, they’ll suds up sills to wipe away dust and accumulated grime, and they'll scrub soiled screens for an extra fee ($1 each). An exterior-only clean endows fixed-plate windows ($2.75 each), double-hung windows ($4.50 each), and triple-track storm windows ($12 each) with enough sparkle to make diamond-encrusted neighbors jealous. Or, homeowners can opt for an interior-exterior cleaning, and careful cleaners will shed shoes before entering abodes to avoid leaving footprints on carpet ($5–$18/window).
