Baldwinsville Chimneys: The Masonry and the Lining Together

Masonry, lining, and which counter
Three things to settle before a price. What the stack serves now, because the lining has to suit the appliance connected to it and that is a separate question from whether the brick is sound. Whether the shell and the footing match what the code describes, since a chimney founded above frost depth keeps moving whatever is done at the top. And which counter, because Baldwinsville is an incorporated village running its own code enforcement program, as state regulation requires of every municipality that enforces the Uniform Code.
The lining has to suit what is connected
The code requires masonry chimneys to be lined with material appropriate for the appliance connected, walls of solid units or hollow units grouted solid at not less than four inch nominal thickness, and footings of concrete or solid masonry at least 12 inches thick extending six inches beyond the support wall, founded below frost depth.
The village runs its own program
State regulation requires every city, village, town and county responsible for administering the Uniform Code and the Energy Code to establish its own code enforcement program by local law, ordinance or other appropriate regulation. Baldwinsville is an incorporated village, so its counter is the one that answers for your address.
Old stacks, newer appliances
56.7 percent of the village was built before 1980 and roughly 43 percent since, on a median build year of 1975. That mix means a good number of stacks built for one kind of appliance are now connected to another, which is a question worth asking before the masonry is priced.
What a chimney has to be, and who enforces it here
The Residential Code of New York State requires in Section R1003.2 that footings for masonry chimneys be constructed of concrete or solid masonry not less than 12 inches thick, extending not less than six inches beyond the face of the foundation or support wall on all sides, and founded on natural undisturbed earth or engineered fill below frost depth. Section R1003.10 requires masonry chimney walls to be of solid masonry units, or hollow units grouted solid, of not less than four inch nominal thickness. Section R1003.11 requires masonry chimneys to be lined, with the lining material appropriate for the appliance connected. Section R1003.10.1 requires that where masonry is used to veneer a frame chimney, through-flashing and weepholes be installed as required by Section R703.

What chimney repair involves
Why a Baldwinsville stack gets scoped with its appliance
A chimney is not only masonry, and quoting it as though it were is how people end up paying twice. The code requires masonry chimneys to be lined, with the lining material appropriate for the appliance connected, on walls of solid units or hollow units grouted solid at not less than four inch nominal thickness, over a footing founded below frost depth. In a village where 56.7 percent of the housing predates 1980 and roughly 43 percent came after it, plenty of older stacks now serve newer appliances, and that combination decides the scope.
What does the chimney serve now?
Send the Baldwinsville address and say what is connected to it. That changes the scope more than the brick does.
Chimney questions from Baldwinsville owners
We put in a new furnace and now the chimney is staining. Connected?
Very possibly, and it is worth raising with whoever looks at the masonry. The code requires a masonry chimney to be lined with material appropriate for the appliance connected to it, so an older flue serving a newer appliance is a legitimate question rather than an upsell. Staining on the outside of a stack usually means moisture is moving through the masonry, and the cause can be above the roof, at the flashing, or inside the flue itself.
Who do we deal with for a permit in Baldwinsville?
The village. Baldwinsville is an incorporated village with its own code enforcement counter, and state regulation requires every city, village, town and county responsible for enforcing the Uniform Code to establish its own program by local law or ordinance. So the answer for your address comes from the village office rather than from a neighboring town's practice, and it is worth asking before a crew is booked rather than afterwards.
