Air sealing and insulation in Chicago : HomeImprovement made me double check the attic, where we have small patches of insulation like bad dust bunnies under a bed. So basically no insulation. So I started on our local gas provider's website (nicor) and got insulation quotes from 6 of companies they recommended. Most were over the phone quotes to air seal and blow in cellulose for around $2,000.
