First things first - bricks or blocks ?
Second things second - high difficult heritage home ?
.... or the back yard BBQ pit ?
You are beginning to understand the futility of this sort of
internet guessing game .. yes ?
To get a rough idea, estimate job time and material cost.
My not so educated guess is 2 guys all day for a job like that.
Not sure about typical rates, but maybe $100/hr.
Bricks are pretty cheap unless you have something unusual.
Google says .50 a brick.
So maybe $1700.
Thanks for the rough idea. As this is a two story house with most of the bricks to be replaced
closer to the top of the chimney, I would assume that scaffolding would have to be used so that
would increase the cost by 10% or 20% or so?
If you are moving soon, just have the bricks replaced. If you are
planning to remain in the house more than about 4-5 years, you need to
take care of the reason why those bricks spalled - water seeping into
the bricks and then expanding/contracting as the water freezes/thaws in
winter weather. The problem is more common when the chimney vents a
fireplace that is rarely/never used, or vents a high efficiency furnace
where the exhaust gases are much cooler than from traditional furnaces.
There are several reasons why water can get into the bricks. A
competent chimney repair person will know how to diagnose and treat the
cause. Often the problem is as simple to deal with as a new, larger
chimney cap. Sometimes there has been a loss of mortar and you need to
have all the mortar repointed. Just replacing the bricks is likely not
a long term fix.

Good point on figuring out if there is an underlying problem that needs
to be addressed. One common problem is people replace an old gas furnace
with a high efficiency, direct vent one. That vents separately, but
that leaves the existing gas water heater on the old chimney, which is
now over-sized and condensation that doesn't get cleared results. Those
chimneys should have a liner installed.
