Seamless aluminum gutters run roughly 6 to 13 dollars a linear foot installed, with steel above that and copper far above. On an average house that is around 1,000 to 2,500 dollars. You pay a little more than sectional because a forming machine and its operator come to your house to roll the gutter to length on the day.

The coil the machine forms sets most of the price.
| Material | Typical installed range |
|---|---|
| Aluminum, seamless | $6 to $13 per linear foot |
| Galvanized steel, seamless | $9 to $20 per linear foot |
| Copper, seamless | $25 to $45 per linear foot |
Only the corners and the outlets have joints, which is where a seamless run resists leaks that a sectional run develops. For the wider cost picture, see the full cost picture.
Because the gutter is made on site rather than bought in ten foot lengths and clipped together. That means equipment and labor at your house, but it removes most of the joints where sectional gutter eventually leaks.
For most houses, yes, because the failure point of sectional gutter is the joint, and seamless removes nearly all of them. The exception is a short simple run where sectional is cheap and easy to replace.

Usually a modest premium per foot, since the forming machine and operator come to the house. The payoff is far fewer joints to leak later.
For most homes, yes. The joint is where sectional gutter fails, and seamless removes almost all of them along the straight runs.
Not really. The run is formed on site by a machine most homeowners do not have, so seamless is effectively a professional install.
They can, at the corners and outlets, which are the only joints. Those are far fewer than on a sectional run, so leaks are less common.
