Here is the honest part. If your door is original to a house built in the 1954-1984 wave and the track, hinges, and panels are all showing their age at once - not just the spring - putting another repair into it is often throwing money at a door that is going to need the next part in six months anyway. We will tell you when that is the case instead of stacking small fixes.
Cold-climate wear is part of this too. In a severe cold band like ours, steel takes a harder beating than it would somewhere milder - rust at the bottom panel seam, brittle weather seals, hardware seized from years of temperature swings. A rusted-through bottom panel on an otherwise sound door is a panel swap. The same panel on a door where the springs, rollers, and opener are all original and tired is usually a full replacement conversation, and we will say so rather than sell you a patch.
We don't do new construction installs on homes that haven't been built yet, and we don't carry every obscure discontinued opener board - if yours is one of those, we will tell you straight instead of guessing at a fix.
