For a new install job in Vail, the sizes we bring depend on the rough opening, and on homes from this build era that opening is usually standard - 16-foot double or 9-foot single, framed to a header height common to tract construction from the 2000s. We carry insulated panel doors rated for the heat band this area sits in, along with torsion spring sets sized to the heavier insulated door rather than the lighter original panel, since swapping to a heavier door without resizing the spring is one of the more common install mistakes. Openers get matched to the new door weight too, not just reused from the old setup. One honest limit here: some specialty sizes, custom window-panel configurations, or non-standard header heights aren't something we carry on the truck and have to be special-ordered, which adds lead time before install day. If your opening is a standard size, that's rarely an issue.
