We don't post a flat number for Aztec repairs here because the fix depends entirely on what's installed and how it's been modified over the years - and on a house from this era, that varies house to house more than it does in newer construction. A straightforward torsion spring swap on original, unmodified hardware costs less than untangling a mismatched extension system with missing safety cables.
Aztec's median household income sits lower than the wider area average, and we know that factors into whether a repair or a partial replacement makes more sense on an older door. We'll always quote the repair first if the door and track are sound - replacement only gets recommended when the frame, track, or opener is too far gone or too obsolete to patch reliably.
The 12-mile drive from Farmington is built into how we schedule, not into a surcharge on the invoice. We give the number for the actual job once we've seen the door, not before.
