NYC MC 810.3 Smoke test

NYC DOB

To determine the tightness of chimney construction, a smoke test shall be made in accordance with the following conditions and requirements:

  1. The equipment, materials, power and labor necessary for such test shall be furnished by, and at the expense of, the owner or holder of the work permit.
  2. If the test shows any evidence of leakage or other defects, such defects shall be corrected in accordance with the requirements of this chapter, and the test shall be repeated until the results are satisfactory.
  3. The chimney shall be filled with a thick penetrating smoke produced by one or more smoke machines, or smoke bombs, or other equivalent method. As the smoke appears at the stack opening on the roof, such opening shall be tightly closed and a pressure equivalent to 1/2-inch (13 mm) column of water measured at the base of the stack, shall be applied. The test shall be applied for a length of time sufficient to permit the inspection of the chimney.

What Our Customers are Saying…

We were very happy with the service provided by Guaranteed Chimney and the technician Ricky. We were also happy to have the referral from John at Petro. It was a good one. Rick was clear and concise and explained what he was going to do, where and how.

I felt comfortable with him in our home. He gave us an estimate on further chimney work which was also clearly written and explained. I felt he was honest, many chimney companies are not.
