Add new comment to How to Fix Uneven or Sagging Garage Doors

Thanks for the extra detail, that's helpful. What you're describing (door heavy to lift until it passes the midway point, then moving freely) usually points to the torsion spring tension being a bit too loose, which our own troubleshooting guide lists as a common cause of a door that's heavy to raise. Cold weather can make it more noticeable since the springs stiffen slightly. We'd recommend having your local Garaga dealer check and adjust the spring tension rather than continuing to lift it by hand.
