Behind closed garage doors, cars deceivingly dance to Billy Joel's "We Didn’t Start the Fire" as they pillage boxes of fireworks and launch roman candles at loaded gas cans. Ensure your car retains moments of much-needed privacy with today's Groupon: for $29, you get one garage-door tune-up (residential or commercial), including structural and electrical inspection, lubrication, and adjustment, from the Overhead Door Company of El Paso (up to a $75 value).

As part of the internationally recognized Miner Corporation, Overheard Door maximizes auto-shelter capabilities with its full line of residential and commercial door-service solutions. Technicians perform full inspections of residential ($65) and commercial garage ($75) doors, targeting 14 different areas that ensure door tracks retain smooth dance moves and weather-resistant sealing. In addition to safe scrutiny of motors, brakes, and clutches, lubrication of springs, chains, and rollers give head plates and bearings peace of mind, preventing future unhinging, regardless of stress levels. Tension checks and counterbalance adjustments round out the service to more than 20 points that will keep garage gates running smoothly through situations involving inclement weather patterns and overloaded luggage racks.

When purchasing Groupon, specify whether it will be used for a commercial or residential door. Those with nonoperational garage doors may purchase the Groupon and use $65 toward garage repair or replacement.
