My dad hired a tuckpointer to rebuild a brick chimney, maybe a little larger than typical residential as it services a small multi-unit building built in the 1920's. The width on all sides is 4 bricks of standard size. The original chimney was about 25 courses of brick and about every 5th or 6th course the bricks would be turned sideways to tie the inner and outer layers of brick together.
I went to look at the job today. About 10 or 12 courses of brick are in place and none of the bricks are turned sideways.
The top 6 courses of brick were single layer, and his worker had told me he'd be putting the inner bricks in place later. Sure enough, the tuckpointer says he lays about 6 courses of outer brick, then lays the inner brick, and tying it together with wire.
I'd like to know if its acceptable practice to rebuild a brick chimney in this manner, and if so, is it preferable to rebuild it in the original manner (with some of the bricks turned sideways.) TIA
