Stamped concrete can be done to look like everything from brick, to
cobble stone, to slate. In your case, compared to real brick, it will
be a lot less expensive. Properly done, it looks real good, however
it will never look as good as real brick, slate, etc. It also needs
to be periodically resealed, about every 2 years for outside use, I'm
sure you'd get much longer inside.
I suggest you go see some areas your contractor has done to see how
you like it.
