garage door maintanence
Its been almost 2 years since we moved into our 20 year old home. We have 2 garage door openers. One make a nasty sound when opened and closed though it has not gotten better or worse and everything functions correctly. These are chain driven by OHD company. I was wondering if there is some sort of maint that should be performed periodically? I asked a neighbor who said to stay away from the 'well' visit services offered. He said they charged him for a well visit and left him with $100 in suggested parts and labor plus a quote for a new opener on the one side. He said that was 5 years ago, he did NOTHING and every thing is still working.
What should I do, reccomendations etc etc?
