I cannot believe the difference this has made with the temperature in our house!  Our furnace does not kick on nearly as much, we don't notice the drafts,  the temperature is comfortable, and it has reduced some of the outside noise!  I am actually kinda excited to get the utility bills to see the difference this has made.  Oh.. and we have not had to run our space heater in the dining or son's room...and we actually turned down the thermostat by 2 degrees! All of it was done from the outside of your house!! They were professional, disclosed everything, super nice!  I would totally recommend this if you are looking for better insulation and don't want to gut the inside of your home.”
