"The guys were really neat. They set up a tunnel from the attic to the back door. There really wasn't much to clean up after. They vacuumed out the old insullation and laid in new. It's hard to say if they did a good job in the attic, because I don’t know what its supposed to look like. They were in the attic almost about 7 hours. The only issue was that they said the senior discount on their Angie's list page must be old so they didn't honor it."
