How to Fix a Crack in My Chimney Bricks?
Asked by BrickNinja99
I've got a crack in my chimney that seems to be just in the brick itself. I'm wondering if it's okay to fill it with a caulk that's suitable for the job. For some context, I live on the Southern California coast where the temperature rarely goes above 80 and never dips below freezing, plus my house is only about 2 miles from the ocean.

It really depends on where the crack is! If it's between the bricks in the mortar, you might want to use a mortar repair compound instead of silicon. The mortar repair stuff usually looks better and works more effectively for that kind of issue. Just a heads up!
