Originally built for cars, garages have evolved into storage units capable of protecting tools, sporting goods, and the identities of the world’s least famous rock stars. Pat your auto shack on the back with today's Groupon: for $55, you get a garage-door tune-up from CSS Garage Doors (a $119 value). This deal is valid for homes throughout the metro Atlanta area.

CSS technicians can treat most any brand of garage doors and automatic openers during an extensive inspection and tune-up. First they will visually inspect the home's steel and plastic porthole while performing an extensive 21-point inspection. Next, aperture experts will perform any necessary setting or tracking adjustments and lubricate the unit's door, opener, and steel-plated doggie door. If more serious problems arise, CSS's technicians will discuss any needed repairs with the customer and receive approval before moving forward (additional repairs are not included in today's Groupon). All CSS technicians are licensed and insured, and can help ensure that garage doors remain limber and strong, and that they won't be pried open by lawnmowers looking to sneak out late at night to give the neighbor’s grass a crew cut.
