We sell a variety of product lines including Door link, Amarr, Clopay, and Mid America to name a few. Just as it is common practice to have your home's heating and cooling systems checked annually, it's also a good idea to have your door checked annually by a qualified service technician to ensure that it continues to work properly and effectively. Moving garage doors can also cause serious injury, or even death. While you can, and should, perform some garage door system maintenance yourself, like lubricating your rollers and hinges, there are many tasks you should not perform yourself (including garage door installation and garage door spring replacement).
