Should not be all that terribly expensive to have it retrofitted.

I wonder if your building has shifted, given your paint line, and that
might mean that your track is out of whack, and binding.

As for comparing the tension, start by going inside and pulling. Then
get the door about halfway up, which so far as I recall is the point
where the springs are slackest, and tug on the cables again.
