Contractors Cost to Replace 20 Spalled Chimney Bricks??

I have a chimney that has about 200 bricks of which about 20 are spalled. What can I expect a contractor to charge (ballpark) to replace the 20 spalled bricks. Location is Central NJ

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 ? John T.

You'll have to get estimates. Or do it yourself. It's not overly hard to do if you take your time and use the right materials.

Saying you are in Central NJ isn't very useful.
Replacing 20 bricks in Princeton will cost way more than 20 bricks in Trenton.

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?

Set up, tear down, rental on the scaffolds, add another day at least. Might double the cost. It's harder to do the work climbing up and down.

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.
