A panel replacement starts with pulling the section that's damaged and checking what's bolted to it - end stiles, rollers, sometimes a strut if the door runs wider than 9 feet. On a door from the 2014-or-later stock common in Cumings, matching a single panel to the rest of the door is usually possible because the manufacturer run and sizing are still current. We pull the hinges, free the rollers from the track, swap the panel in, and reset everything before checking that the door balances on its springs the same way it did before the damage. If the springs are already tired from that same age of door, we'll flag it, but we don't replace a spring that isn't the reason you called us out.
