Chimney Removal Cost
Chimney removal can mean taking down only the above-roof stack, removing the chimney through the house, or demolishing an attached appliance and venting system. Those scopes have very different costs.
Stack-only removal
Even exposed-stack removal can require roof protection, masonry demolition, disposal, roof sheathing and covering repair, flashing, and weatherproof closure. The remaining chimney below the roof must be stable and intentionally abandoned under applicable requirements.
Full removal
Removing the interior stack can add floor, ceiling, wall, chase, attic, and finish repairs. Structural support, fire separation, access, dust control, and disposal may dominate. A quote should show each level affected.
Check appliances first
An apparently unused flue may still connect to an appliance. CSIA guidance considers connected appliances and flues. The Napoleon S25 manual is one model-specific example that calls for a sound chimney, qualified installation, local authority consultation, and no shared flue with another appliance. Do not generalize it, but do not remove a chimney without an appliance and venting assessment.
The evidence does not establish a reliable national removal price or Canadian benchmark. Ask for demolition, access, roof closure, interior restoration, structural review, venting redesign, permits, disposal, and cleanup as separate lines. Compare with chimney rebuild cost.
