Can anyone recommend someone reasonable who installs attic insulation? I recently had one of those OG&E energy audits, and they recommended I get about 12" of additional insulation in my attic.

I used this companyCribbs Silver Creek, http://www.cribbssilvercreek.net/home before last winter. I was very pleased with their work. Would definitely use them again.

If you can afford it the foam insulation is the way to go.
It’s made a big difference at my home.
