CHIMNEY REPAIR?

Question on chimney repairs. I've lived in this house for 4 years now, and every year I notice more pieces of brick falling off my chimney. I've plugged some of the holes up with mortar, but every year there is more damage. The chimney was built in 1975 and I think it is concrete block with a brick fascia? If I go the tuck pointing route I'd be doing it every year. What about some kind of cement covering right over the bricks? Thanks.

Yes, I'm in a freeze thaw zone. It's more like the bricks are crumbling apart, not the mortar.

When bricks chip away like that isn't it called spalding? Aren't the bricks essentially rotted?

That's what it is "brick spalling" Crapola, So what do you think, can I cover it all up with some kind of stucko or cement, or just rebuild sometime in the future.

Don't know if the brick was used or not, but its the same brick inside and out.

The chimney brick looks like it is used as a fascia around concrete block. Don't think it's structural.
