We don't have a published price list for this page, and quoting a number we can't back up would be worse than saying nothing. What we can tell you is what moves the price: whether it's a spring swap versus a full torsion conversion, whether the opener needs replacing or just a sensor realignment, and the width of the door - a three-car opening on a house built for that income tier costs more in steel and spring wire than a standard single. Castle Pines carries a median household income well above the wider Aurora service area's $92,450, and the housing stock here tends toward wider, heavier doors than a lot of the older neighborhoods we run trucks to, so parts cost is usually the bigger line item, not labor. If you want an actual number, ask for a quote before the truck rolls - a phone estimate on a spring job is normally close, but a torsion conversion or an opener with a dead circuit board can shift once we're looking at it in person.
