DO you care about burning the house down.. or dying from carbon monoxide?
Fireplaces are not something you want to treat casually when anything is wrong.
Cracked firebrick need replaced... and you HAVE to use the correct materials... its special materials and special mortar... and you won't find it at Home Depot or Lowe's. (at least the ones where I live don't have it).
I'd recommend getting a professional experienced with fireplaces and chimneys to do the work.

Special brick, fire bricks, have to be used to withstand the heat. No you can't do it yourself.
Is the damage inside or outside?

It takes a very specific and special mortar mix... no other type of mortar is suitable.

Yep... I rebuilt one of my fireplaces 14 years ago. (have two in my house)... after a LOT of research and talking to professionals in the field I knew that walked me through it... definitely not a DIY project for the average person.
Firebrick in the firebox... and I don't even remember the correct mixture for the mortar needed.
Too much can go wrong if its not exactly right, and what can happen when it does is very serious.

Have him tell you what he's using in the mortar... exactly... fire-clay is a major component of the mix, I don't remember exactly the rest of the mix...
And it HAS to be firebrick... firebrick is not glazed.. and looks more like sandstone than any other type of brick. And made from different materials.
This is way different than laying regular brick... though it might appear similar to someone that's not familiar with what to avoid.
And its been so long I since I did it I honestly would not want to give anyone tips or directions that I learned to do it at the time. Because I'm not sure how much I might have forgotten since then.
All the warnings I was given I do remember quite well.

I am not an expert, mr. Lee jack, but know you can't do this yourself and it is fire bricks you need. If you use this for a heating source, fhen you owe it to yourself to get it done properly, yes ?

Absolutely not... they are very different than the mortar needed for a fireplace. Both of those would literally explode (well spall violently is more like it) when subjected to a fire that close and to that heat.
