The normal use of your Garage Door and Opener does cause some of the parts to wear down and even break at times. This is not unusual but it can also create some safety issues if they are not addressed immediately. Overhead Door Company of Allentown sells all of the parts that are used for our Garage Doors and Openers over the counter. You can stop in our showroom and speak with a salesman to get you the proper parts that you need. Most parts are in stock at our warehouse. If something needs to be ordered we will receive it in a timely matter.
