Our vacation cottage has no insulation under the floor, which worries me...the utility bills are not too high, but the groundwater table is high and moisture will definitely eventually attack the underfloor plus it also rises up into the house through various wall cavities (plumbing holes, etc.)
I was thinking of possibly spraying 2" of foam under the floor - it has floor trusses and seems easy to get at.
I noticed there are now some DIY kits for this, but not sure it would be worth doing myself. I go under there regularly, so that is no problem in itself.
Does anyone have any info on the DIY or on the general prices for getting it done by a pro? I had one friend mention that it would cost about $1. per square foot per inch of thickness....does that sound right?
Unfortunately, it is not my primary residence, so no tax credit would be forthcoming!
