We don't publish a flat number for new door installs because the price swings on door size, insulation, opener choice, and what the existing opening needs before a new door goes in - and that last part matters more in a neighborhood like this one, where the housing stock is close to sixty years old, than it would in a newer tract. What we can tell you is what drives the number: a straight double-door swap onto sound existing hardware costs less than a job where we're also replacing bent track, an undersized header, or a spring system that's the wrong size for the new door's weight. Carson's median household income sits at $107,391, higher than the wider service area's $101,138, and we mention that only because it means we don't default every quote here to the cheapest option - we'll spec what fits the house, not just the budget. Ask for the breakdown when we quote, not just the total, so you know which part of the number is the door and which is the labor to make an older opening work with it.
