If they're not cleaned every few days, your windows will turn black and begin emitting a high-pitched scream that makes dogs pregnant. Prevent a neighborhood outbreak of puppies with today's Groupon: for $49, you get window cleaning for up to 20 exterior windows from Cal Services (a $100 value). This Groupon is valid for homes within the Fresno and Clovis city limits.
Cal Services thoroughly scrubs windows with an undying dedication to consistently successful service. Using a secret concoction of potent products, Cal Services' window-wiping wizards purge glass of dirt, grime, and ladybug tears to leave house eyes clear and shiny. Glass burdened with calcium deposits can be scrubbed clean for an extra charge, and houses with more than 20 exterior windows can get additional windows cleaned for an extra $5 each.
