Okay, here’s my blog post about replacing fireplace bricks, written in a casual, personal style, focusing on the process:
So, the other day I looked at my fireplace and thought, “Man, those bricks are looking rough.” Some were cracked, a few were loose, and the whole thing just looked… tired. I’m no expert, but I’m pretty handy, so I figured, “Why not try to replace them myself?” Big mistake? Maybe. But it worked out in the end!

Getting Started (And Feeling Overwhelmed)
First, I took a bunch of photos. I wanted to remember how it all looked before I started messing with it. Then I went to the hardware store. Let me tell you, there are a LOT of different kinds of bricks. I ended up grabbing some that looked pretty close to the originals, plus some mortar mix. The guy at the store gave me a few pointers, which was helpful.
The Demolition Phase (aka Making a Mess)
Back home, it was time to get destructive. I put down a drop cloth to try to contain the mess (spoiler: it didn’t really work). Then, using a hammer and chisel, I started tapping out the old bricks. Some came out easy, others… not so much. It was slow going, and honestly, pretty dusty. I definitely recommend wearing a mask and eye protection for this part. My biggest advice is be patient. Dont go bashing it, gently and repeated tap at it.
Brick by Brick (Literally)
- Chipping away old mortar: Once the old bricks were out, I had to chip away the old mortar that was left behind. This was probably the most tedious part.
- Mixing the new mortar: I followed the instructions on the bag, mixing the mortar mix with water until it was the consistency of, I don’t know, thick peanut butter?
- Laying the new bricks: I spread a layer of mortar on the bottom of the opening, then carefully placed the new brick. I used some little spacers to make sure the gaps between the bricks were even.
- Repeat, repeat, repeat: I just kept doing that, one brick at a time, until the whole area was filled in.
The Finishing Touches (And a Sigh of Relief)
After all the bricks were in, I let the mortar dry for a couple of days. Then I went back and cleaned up any excess mortar with a wet sponge. It wasn’t perfect, but it looked a whole lot better than before. I even used a wire brush to kind of “age” the new bricks a little, so they blended in better with the older ones.
I learned that patience is vital for this kind of a DIY task, and you will make mistakes, and that’s OK.
Overall, I’m pretty happy with how it turned out. It was definitely a learning experience, and it saved me a bunch of money by doing it myself. Would I do it again? Maybe. But next time, I might wear a full-body suit to protect myself from the dust!
