This client needed to get their chimney up to code so requested an inspection. The chimney was brick lined and had cracks throughout.
We recommended relining the chimney using 10gage stainless steel.
We obtained the plans and permit for the chimney installation.
For the project we erected scaffold on the roof for access to the top of the chimney for the duration of the project. We installed over 75 of round ASTM listed butt seam welded 10gage stainless steel pipe.
We installed a base plate on which to land the chimney. At the base of the chimney we installed a gas tight clean out as required by the NYC DOB.
We also replaced the breeching with 14gage carbon steel and insulated the pipe and installed aluminum jacketing.
At the top of the chimney we installed a custom fabricated chase cover with a cut out and 6” wrap to secure the chimney lining in place.
There was an extension pipe on the chimney before we started so we removed that so we could install the chimney lining. And then reinstalled it upon chimney lining and chase cover completion.
Once the lining was installed we performed a pressurized smoke test and issued the chimney affidavit for NYC DOB and Con-Edison.
