There are two major sources of noise in the garage door, the wheels and the door opener itself.  We had metal wheels and a screw type garage door (we bought thinking it was quiet).  Lacking the desire or skill to replace the door opener we had a professional do it, we replaced it with a belt drive Liftmaster model.  When this was done the difference was striking but not quiet enough.  So we had him change out the wheels.  And here is the trick, he removed the guide on one side and rolled the door down and popped out each wheel and replaced with a nylon wheel.  Very quick and easy.  This is a trick that I had not seen anywhere so I was a bit disappointed in Home Depot and Lowes when I saw how easy it was.  Anyway, after the nylon wheels were installed the door openning is Very quiet.  

Seeing as we have two doors and no desire to pay for another opener, I just changed out the wheels.  It is quieter but not nearly as quiet as the Liftmaster.  So for those out there looking for a quiet door get a belt drive door opener and replace the wheels with nylon ones.  If you think it is still to loud you are insane and should get some help.

Now Nick can get some sleep and we can open the garage door without fear!  A new day at the Andresen household.
