Hydraulic flush?

Just had all brand new hydro brake levers, hoses, etc. installed. I didn't initially get new pads but have since; the brake levers now go full squish almost to the bars. I've bled my brakes before (I have the Shimano kit) but am not sure if the reservoirs simply need more fluid now (to get them to be stiffer/brake with less lever action). Do I just need to re-bleed them?

The mechanic probably pushed the pistons all the way back in order to have enough room to install the new pads. Assuming there is enough fluid in the reservoir (there should be, unless they took some out or spilled some during this process), pumping the lever a few times should eventually push the pistons out far enough to make solid contact again, and firm up the lever.
