Concrete Repair in West Jordan, UT

That's called scaling, and in Utah it's almost always freeze-thaw plus de-icing salt, sometimes on concrete that wasn't air-entrained or was overworked when it was finished. If the slab underneath is solid, it can be resurfaced and sealed. Keep salt off it afterward and use sand for traction.

Usually, when the slab is a good candidate. Lifting a few panels or replacing one section costs less than tearing out a whole driveway. But repairing a slab that keeps failing costs more over time than replacing it once. The free estimate gives you both numbers when both are on the table.

Most small repairs on your own lot don't. Replacing panels in the public sidewalk or the driveway approach usually does, since that's the city's right-of-way. If any digging is involved, 811 gets called first.

It depends on why it sank. If the fill underneath has finished settling and the water problem is fixed, a lifted slab can stay put for a long time. If a downspout keeps soaking the ground, it'll sink again, which is why the cause gets fixed along with the slab.

Not exactly. New concrete starts out lighter and weathers toward the old over a few years. Replacing whole panels at the joints, instead of patching inside a panel, makes the difference look intentional. Resurfacing a whole area gives one even color if matching really matters to you.
