Fireplace mortar repair question

SnoBunnyNovember 2, 2002

The mortar around one of the bricks in the firebox of my fireplace is disintegrated to the point where I can lift the brick right out. I've done a bit of tuckpointing in my life (not the neatest, but I get the job done), so I'm comfortable with the idea of replacing the mortar, but I need to know if there is a special type of mortar used for fireboxes??

I had the same problem when I bought an old house. The mortar was starting to come out of some of the joints in the firebox. I asked exactly the same question to a mason (the kind that build brick walls & stuff) and he said that they use the same mortar in fireplaces as they do everywhere else.

My damage wasn't quite so bad as yours, so I used the premixed mortar patch in a caulking tube and just squirted it in. But if your bricks are coming out it may be worth mixing up some real mortar. Just make sure it's dry before starting a fire.

Hope this helps.

Hey, that really does help, Reef. Thank you! I even still have some mortar mix left from doing some repairs on my front steps, so I won't even have to spend a cent to do this home repair!
