I got a whole level of one of my rental houses done this summer. After researching the prices no one could beat Home Depot. The company they used for insulation was very quick and efficient. The $35 fee for measuring goes for the purchase price so its really no lost money unless you choose to not go with them. The $99 installation fee covered everything including transitions and tack strips. They even left the larger pieces for rugs or whatever. I rented a dumpster for the removal of all the old carpet and padding, it was about $300 and I did it myself and had the whole house sans carpet when the installers measured and installed. From the ordering of the measurement to installation was about 4 days.
