Family owned business! Rob has insulated my private home and my rental multifamily with blown-in insulation. He is friendly, honest, reliable, and cleans up his work. I have reduced my home heating oil consumption by more than 35% in each property. He blows in cellulose insulation and also does door kits and will seal gaps around windows. He comes when he says he will, and he leaves everything neat and clean. Calnan's is family owned for many years. He does not exaggerate when he tells you how much it will reduce your energy consumption (and it makes your house more quiet, too!). Unbelievable, actually. Could not possibly recommend him and his service more highly (I did the research -- cellulose is superior to fiberglass).
