Have a broken garage door torsion spring in the N/NW Chicago and suburban area? We can help. We replace torsion springs on a daily basis in the N/NW Chicago and suburban area at a fair price. We provide 20,000+ high cycle torsion springs as standard - not an upgrade. Torsion springs are located on a bar above the garage door When one breaks you will see a gap of an inch or more between the coils. Typical cost for a 2 car residential garage door is ONLY $200 parts and labor to replace both torsion springs. There are NO hidden costs, travel charges to the N/NW Chicago and suburban area, inspection fees, lubrication fees, or just because fees like some of our competitors. Our service includes general maintenance, lubrication with synthetic garage door lubricant from Clopay and inspection of the garage door and adjustment of the garage door opener.

Does your garage door opener have bad gears in the N/NW Chicago and suburban area? If you hear the garage door motor running but the chain or belt is not moving then there is a very good chance the the plastic gears in the garage door motor unit are stripped or cracked. For garage door openers manufactured by Chamberlain - including Chamberlain, Liftmaster, Sears / Craftsman, Access Master the cost to replace the gear and sprocket assembly (includes both plastic gears, output shaft, sprocket for chain or belt, bushings and lube ie 41C4220A, 41C4885-2, 41C4885-5) in the N/NW Chicago and suburban area is ONLY $145. Just like above discussion on springs this cost includes general maintenance (tune-up) etc. As long as your opener was manufactured after 1992 and has the ir safety beams near the garage floor on both sides of the garage door opening then the gear and sprocket replacement is usually justified.

Is your garage door lift cable broken in the N/NW Chicago and suburban area? The garage door cable is the metal cable (wire) that connect the springs to the bottom section of the garage door. When a cable breaks the garage door will usually become uneven (higher on one side than the other) and will usually not be able to open with the garage door opener. The cost to replace both cables on a residential garage door in the N/NW Chicago and suburban area is ONLY $125. Cable replacement is about $25 additional when replacing the torsion springs since you already have the labor costs included in the $200 spring replacement.

Are you ir safety sensors bad in the N/NW Chicago and suburban area? Since 1993 all residential garage door openers require self monitoring entrapment protection in order to be sold in the US. Almost all opener manufacturers have opted for the ir safety sensors aka photo eyes to meet the UL325 standard. The standard calls for these sensors to be mounted within 6 inches of the floor with one on each side of the garage door opening. If these sensors are damaged, misaligned, or defective then the garage door opener will not close from the remote control. The standard allows a user within the sight of the garage door to hold the push button / wall console continuously in order to override the problem sensors. There is an aiming light on the sensor system (usually a light on each sensor with the exception of Allstar, Challenger and some Genie). Both aiming lights need to be on steady - not flickering in order for the door opener to close with a remote control transmitter. If the sensors are bad the replacement cost for a pair of photo eyes in the N/NW Chicago and suburban area is about $125 including the general maintenance, lubrication etc as described above.
