Labor
The labor required to build a chimney depends on the thickness of the walls, the height, and the amount of cutting to build in specialties, provide offsets, etc. In general, a mason will take 16 hours with 8 hours of laborer's help to lay 1,000 brick. On this basis, 16 by 6.1 = 97.6 hours of mason's time and 48.8 hours of laborer's time will be required.
Cost
The approximate cost of the chimney can be determined by using actual local cost of materials and wages as follows:[F]
| 6,100 brick at $15.00 per thousand | $91.50 | |
| 27 sacks of cement[G] at $0.70 per sack | 18.90 | |
| 16 bags of lime at $0.50 per bag | 8.00 | |
| 5 cubic yards of sand[G] at $2.25 per cubic yard | 11.25 | |
| 1 cubic yard of gravel at $2.00 per cubic yard | 2.00 | |
| 98 hours, mason's time, at $1.00 per hour | 98.00 | |
| 49 hours, laborer's time,[H] at $0.30 per hour | 14.70 | |
| 28 linear feet of 8½- by 13-inch flue at $1.00 per foot | 28.00 | |
| 20 linear feet of 13- by 13-inch flue at $1.15 per foot | 23.00 | |
| 20 linear feet of 8½- by 8½-inch flue at $0.40 per foot | 8.00 | |
| 1 8-inch thimble | .60 | |
| 1 6-inch thimble | .40 | |
| 2 clean-out doors Damper, lintel mantel, ash dump | } | 65.00 |
| Total net cost | [I] | 369.35 |

[H] Includes labor for footing and cap.
[I] Where the chimney is built by contract, 10 to 15 percent should be added for profit and overhead.
