Maintaining Your Garage Door and Opener
Regular maintenance and inspection will help keep your garage door in good working order.


1) Door panels- Inspect for obvious damage in/out. 
    Touch up any scratches as soon as possible to prevent rust. 
    REMEMBER, warranties do not cover rust caused by scratches or damage! 
    Run your door up and down, making sure the panels fit together properly.

2) Moving parts- Visually inspect all moving parts. 
    Check for loose bolts, loose or cracked hinges, worn rollers, and frayed cables. 
    Oil all rollers and bearings with a light spray oil. NEVER use grease in the tracks!

3) Tracks- Check for excessive play, wear, or damage. 
    Check for loose track bolts and other obstructions to door movement.
    Inspect track hangars to ensure they are not loose.
    Make sure the tracks are free of grease and excessive dirt. 
    Spray a light coating of oil in the tracks.

4) Astragal- (Bottom rubber seal) Inspect for excessive wear and tear. 
    Wipe it with a rag and silicone spray. This helps it stay flexible, and prevents it from  
    freezing to the ground in winter.

5) Check spring adjustment- With the door DOWN, disengage the opener. 
    Manually lift the door. It should not require excessive force to raise the door. 
    It should stop and stay in place about half-way up. 
    Raise the door all the way, the door should also stay up. 
    If the door requires excessive force to lift or close, or will not stay in the up position, 
    the springs need to be adjusted. 

           Call Spero Door at (630) 728-8921 

We will come out quickly and get your door in good working order.

Automatic Openers-

1) Test the safety beams and force settings as specified by the manufacturer. 
     NEVER compensate for weak springs or a sticking door by increasing the force settings!

2) Visually inspect the hangers that suspend the machine from the ceiling. 
    They should be solidly bolted to the machine and to the ceiling or cross members.

3) Chain drive-Check the chain tension and adjust according to manufacturers specifications. 
    A light coating of oil will help extend chain life. 
    If the chain rail is made up of sections, make sure they are bolted together tightly.

4) Screw drive- Visually inspect. Most screw drive openers have a sectional screw assembly.
    Make sure all sections are fitted together tightly, and properly lined up.
    Screw drive operators are notorious for "freezing up" in cold weather. 
    If yours seems to be sticking, spray the entire length with lubricant, and let it sit for a few                  minutes. 
    Pull the release on the door, and push your wall button, to let the screw turn by itself for a                minute.  Then, reconnect your door and try it again. 

If you still have difficulty, call Spero Door (630) 728-8921.
