Short version: Both our main level garage doors are sticking to the floor. Can't figure out why.
Long version: Sometime last year, I noticed both garage doors we frequently use were making a loud noise and a jerking motion when first opening for the day. If you open them again in the next hour or two, the symptoms are greatly reduced.
I'm fairly certain it's the gaskets sticking to the floor. While I can't 100% rule out something along the bar or in the motors, the timing, visual review, and other info I'm about to share make it unlikely.
Important info:
Our garage floor was painted with garage floor paint 16+ years ago, which included an etching agent.
I've attempted to mitigate by cleaning the gaskets and where the gaskets touch with Simple Green and Dawn both, neither of which seemed to make a difference.
I tried sprinkling a light dusting of sand to see if the texture would stop the sticking, but it did not.
I've also replaced both gaskets twice. You get temporary relief for a day or three before the behavior returns.
I've put painter's tape on both the gasket and the floor, which also provides temporary relief for a few days.
The only "permanent" relief has come when I put down cardboard strips where the gaskets land, but that's impractical long term.
The sticking stops in cold weather. Think 30's and lower. One day back above 50, and they return to sticking.
I think this started about the time we switched from Orkin to our current pest control service, and mentioned this to our tech, who said he would try avoid directly spraying the gasket area. I also timed one of the gasket replacements right after one of his visits, but saw no difference in the relief period.
The gaskets I use are T-seals similar to this:

At this point I think my next try will be to go for a more expensive rubber gasket over vinyl, but I'm hoping the Pack Hive Mind has some other ideas as well.
