- Lubricating all moving parts on door and opener
- Balancing door for proper weight
- Tightening hinges and making minor adjustments
Those are the key items. The deals vary in price and what is and isn't included. Since I have two garage doors I either buy two deals or just work with the vendor to get a good price.
This time, however, I needed more than a tune-up. The spring on the party door needed replacing. Probably because we use that door in lieu of the actual door to enter and exit the garage. And I'll bet last winter's polar vortex had something to do with it as well. Who knows when it broke, I certainly didn't notice it.
The replace parts cost $324 so it was a costly but necessary discover.
