Received back one of three pricing quotes to air seal and insulate 984 sf in the Northeast USA. The total project price is $16,319. Cost after discounts and rebates is $9,952.00.

I found this price to be astronomical. Anyone agree or know if this is to be expected with the two other pricing quotes?
