I charge a flat rate to service overhead doors. The following is included with this service:
*Check all brackets for bending/wear
*Check for free movement of door
*Lubricate rollers w. silicone
*Lubricate opener chain
*Adjust & lubricate extension/torsion spring(s) if necessary
*Visually inspect opener(s) for any sign of wear or damage.
In essence, if you cannot manually raise or lower your garage door effortlessly with two fingers, there is a problem. Likewise, if you manually raise your door to a mid-level and release, it should not move any more than 1-2 inches on its own, up or down. If it does, your spring tension needs adjusting, and is placing undue stress on your opener each time you use it.
I work frequently on overhead doors and openers, anything from routine maintenance to total replacement. If you suspect an issue, take care of it now before it becomes a bigger expense. Call me! 419-212-3200
