Is this in the ballpark?

This cost estimate seems way high compared to our first estimate but any quick advise would be GREATLY appreciated. My GC gave me the replacement sub's estimate for installing radiant floor to our 350 SF addition using Thermofin. The subfloor has already been installed.

Not including GC's cost on cutting and installing 3/4 plywood around the thermofin:
Two zones: $7,860
One zone: $6,980

Install below floor: Add $1,450 to above costs. (Would have to work in a cramped but new, clean crawlspace).

This installer also recommends a supplemental cadet heater in the bathroom.

The original bid by the guy who did't show up was $3,500 complete, for 2-zone using unnamed underfloor product.

What gives? Any thoughts?
