Question DetailsAsked on 9/26/2014

What does it cost to stucco over painted brick chimney and who does this type of work ? In Columbus, Ohio

The painted brick chimney has bricks that need to be replaced. I have seen stucco placed over the chimney as an option, rather than replace bricks. The chimney is structurally sound, but Chimney repairman said that painted bricks would continue to be a problem. i want to compare cost to replace bricks to stucco work. I an estimace to replace the bricks.
I am looking for a long term solution to the spalling painted brick problem.

Bricks need to breathe or they start spalling and falling apart - whether sealed or painted, as you have seen. Right way to fix this is to replace the significantly damaged bricks, then sandblast the bricks clean (doing that afterwards make them all look more alike than if done first).

I certainly would not do stucco over a brick (or stone) chimney - that sounds like an invitation to faster deterioration for several reasons - you are covering the bricks up again so they cannot breathe, punching a bunch of holes in them to fasten the mesh to them which the stucco sticks to, plus stucco is far from watertight - it lets a lot of moisture through it when wet, so that would just aggravate the issue. You would normally put a water barrier under the stucco to protect the walls from moisture coming through the stucco, but that would act as a seal on the bricks and aggravate the problem again.

Ditto with concrete-facading the chimney, like they have been doing in California for seismic stability - they have found that the bricks left inside deteriorate faster because of them not being able to breathe.

I would suspect the chimney repairman said to replace the bad bricks and rehab the chimney the normal way, and that would be correct.
