A new install on a standard double-car opening, with the old door and track already stripped out, usually runs a half or full day depending on whether we're also swapping the opener and adding insulation upgrades. Because Union's stock skews newer, we're rarely dealing with rotted jambs or out-of-square framing the way we sometimes do in older sections of the service area - the openings tend to be square and the wiring tends to be up to code. That shaves real time off a job. What doesn't change is the cold-climate requirement: this area sits in a severe cold band, so any new door we hang gets sized and sealed for that, regardless of how new the house is. Insulation rating isn't optional here, it's just a question of how much the owner wants to pay for it.
