Any quick advise would be GREATLY appreciated.
Just received a cost estimate that seems way high compared to our first estimate. This is the replacement sub’s estimate for installing radiant floor to a 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, dealing with additional floor high issues, etc:
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 didn’t show up was $3,500 complete, for 2-zone using unnamed underfloor product.
I’m in oregon in a smaller own with few options for experienced RH installers.
Any thoughts?

Pretty please?
Bear in mind my experience with this stuff is pretty minimal. I know for the electric version, wires under tile, just for an average bath (40-50sf) I don't touch it for less than a grand. Radiant is more, and you have the units that go with it, the cost of all the tubing, manifolds, install time, prepping the area to receive the gypcrete, and then dealing with the multitude of issues that (can) occur when your floor elevation jumps a couple of inches. I have no idea if your costs are high, low, or on par. My gut says based on what little I've seen that Mr $3500 was the low bidder for a reason, and you may become thankful that he didn't show.

Thanks for the advice JRF. Hoping for some insight on the cost issues. From what I've seen here and elsewhere is that $8,000 is about what it takes for materals for a very LARGE home. I'm talking about a 350 SF addition.
That's $22.85 per SF. Seems high.
Please comment experienced radiants!

That does seem high, but it's hard to comment without really knowing what's going on. PSF price is not really a fully reliable figure. I'd go ahead and get another bid or two if you can though.-------------------------------------

JRF,
First do you have a boiler already, or was this part of the quote?
Second 8K for materials for large house sounds low to me. I did my own install with the help of a local company. with me installing all the tubing and the pro's installing the boiler cost was 15k for 3700sqft, if they did complete job 22k.
See if you can work with installer to have you install tubing and have him do finish work. May save some cash. Good luck
