My recently purchased home has attic insulation, but I'll be the walls are bare. What is the fix to have insulation put into my exterior walls? I'm hoping that small holes around the walls in question will allow for polyurathane to be squirted in. If not, any suggestions?

Its cold in northern Georgia!

Most home retro insulation jobs are done from the outside of the house. 1 in. holes are drilled top and bottom of all cavities between studs. Most home owners don't own the proper equipment for blowing in the insulation so you might call around and get bids.

I find it unlikely anybody built a house 6 years ago without side wall insulation. Poke around, maybe remove the switch plates and outlet covers. Doing it yourself would be a stretch. The urethane components are toxic, and may not be available for DIY. Once reacted, the modern stuff is safe. So talk to the contractors. Reputable ones should be able to check if you do have side wall insulation.
