Safety is Our First Priority
Door Doctor’s Trained Technicians ensure your door operates safely. With every service, repair, or installation, our skilled technicians will do a thorough safety check of your entire garage door and opener, and all the related parts.
The Professional Difference
With over twenty years of experience, the Door Doctor team will quickly diagnose the problem and prescribe a solution for your garage door. We understand that many people enjoy doing home improvement projects on their own, but due to serious safety risks, we recommend hiring a trained professional to address your garage door needs.
Garage door openers from the home improvement stores are not built the same as openers that the Door Doctor carries.
As an authorized dealer of Lift-Master garage door openers, the openers we carry are built with solid one piece rails. The rails provided with the garage door openers sold at home improvement stores are cut into three pieces to easily fit in your vehicle. This three-piece rail will flex at the joints, which places extra strain on the opener, often when the door is moving. The door is likely to catch and slip as it moves past the joints. This will cause the opener to ware out faster, and is a safety hazard. Also, most retail openers will only work for doors up to 8’ tall.
In addition, the safe and proper operation of your garage door and garage door opener is dependent on the garage door springs being correctly calibrated and balanced for the size and weight of your particular garage door. The springs, cables, and bottom fixtures are under extreme loads and may cause severe and critical injuries without the proper tools, training and knowledge to make this type of repair.
Please Refer to the Safety Information Below and Keep Your Family Safe!
Extension Springs
Function: Garage doors are typically balanced either by torsion springs or extension springs. Extension springs are generally mounted just above the horizontal track, perpendicular to the closed garage door. When extended, they provide lifting power to help open the garage door.
Safety Warning: If an extension spring snaps, broken spring parts can become airborne and cause injury. However, a safety cable, installed inside each extension spring, can contain the spring and prevent injury.
Torsion Springs
Function: Torsion springs are usually mounted above a closed door, parallel and horizontal to the top section of the door. They provide lifting power for the door by winding and unwinding while the door is opened and closed.
Warning: The torsion spring is under high tension and requires special tools for adjustment. Because of this tension, the torsion spring and any part associated with the counterbalance system should be adjusted only by a professional. These parts include: springs, cables, corner brackets attached to the cables, cable drums, and the center bearing bracket that holds the torsion spring shaft.
Corner Brackets
The corner brackets are the two brackets attached to the lower left and lower right corners of the door. The cables that lift your garage door are typically attached to these brackets.
Warning: Since these cables are under high tension, when disconnected the brackets can become airborne and cause injury.
Garage Door Opener
A garage door opener is a separate product from a garage door. Openers are electric motorized devices that open and close garage doors.
The sensitivity of these internal reversing mechanisms can fall out of proper adjustment so that the door will not reverse when it hits an obstruction. You should check your reversing mechanism monthly by setting a two-by-four or a full roll of paper towels on the floor in the path of a descending door. If the door does not reverse after contacting the obstruction, call the Door Doctor to examine and repair your door system.
Warning: Most garage door openers include an internal reversing mechanism that causes the door to reverse when it hits an obstruction. However, garage door openers with inadequate or poorly maintained reversing mechanisms have caused injury and even death to children who are caught underneath motor-operated garage doors.
Lift Handles and Pull Ropes
A lift handle is attached to the door and allows it to be manually opened or closed. A pull rope performs the same function and is usually attached to the bottom bracket in the lower corner of the door.
Remember – if you have a power outage and need to manually close your motor-operated door, don’t close the door by placing your fingers between the door sections!
Warning: The lift handle and pull ropes are intended for use with a door that is opened and closed by hand. But when an opener is attached to the door, the lift handle and pull rope should be removed. Otherwise, they can snag or hook on people or loose clothing while the door is being opened by the operator.
Photoelectric Eyes and Sensing Edges
Photoelectric Eyes are sensors that are mounted about 5-6 inches off the floor on both sides of a garage door. These sensors operate with a garage door opener and send an invisible beam across the door opening. If that beam is broken while a motorized door is closing, the garage door opener will cause the door to reverse direction to the full, open position.
A Sensing Edge is attached to the bottom edge of a garage door. When this sensor contacts an obstruction during the closing of the door, the opener will cause the door to reverse direction to the full, open position.
Warning: A federal law requires that all residential garage door openers sold in the United States since 1993 must include an additional protection against entrapment, such as photoelectric eyes or a sensing edge. The law also requires that, if these sensors become inoperative, the opener will not function. Thus, these sensors are not dangerous, but your garage door opener can be dangerous if it does not have these safety devices.
Remote Controls
Garage door openers are usually operated by a wall-mounted push button, a hand-held remote control, or a keyless entry pad that requires you to enter a numerical code.
Warning: Small children have been seriously injured by playing with the remote controls of motor-operated garage doors. Running under a closing door can be a deadly game. Do not let children play with or use the push button or any remote controls for your door. Keep all such controls out of the reach of children.
Section Joints
A section joint is the area between garage door sections.
Warning: People have been injured by attempting to close a door by placing their fingers in an open section joint and pulling down on the door, thus pinching their fingertips. As a safety precaution, never attempt to place your fingers in the section joint.
