I had them come out and insulate all my walls which already had a mix of 1960's and newer fiberglass bats.

The installation itself was somewhat messy with a clear but somewhat sticky running down lots of my windows and doors for about 24 hrs which if not immediately cleaned up was hard to remove. They cracked one of my vinyl siding panels without saying anything to me (which, if they had, I could have directed them to a replacement panel I have stored in my garage) and the level of the panel was only about a third of the way up my wall which makes me wonder how high up the foam went. One of the room they did they overfilled one or more of the spaces which popped the drywall off the studs and left it bowed out under a window allowing more air infiltration. Where they plugged holes in the drywall in my garage, the plugs shrank and cracked leaving me needing to patch and repaint plus they left lots of drywall dust over my garage.

The bottom line after a year of utility comparisons is that my energy usage actually increased.
