Is Home Additions cheaper in smaller cities?
Often, but not always. Smaller markets can carry a travel or availability premium that offsets a lower local rate, so it is worth checking a nearby city before assuming the lowest published figure applies to you. In Chicago, that is worth confirming with a local provider before you commit.
