Sioux City Demolition Pros connects Sioux City homeowners with local crews who remove old brick chimneys. Houses built when coal and wood heated the city often carry two or three chimneys, and after furnaces moved to power vents most of them now serve nothing but leaks, loose brick and nesting birds.
Taking down an unused chimney above the roof for $500 to $2,500 costs far less than the water damage and rebuilding it causes once mortar washes out, and a full tear-out with the breast and base runs $3,000 to $6,000 if it is left until it fails.
Why old chimneys fail in Sioux City
Freeze and thaw does the work. Water soaks into soft old brick and mortar, freezes, and pushes the joints apart, so the top of the stack loosens first. Unlined flues let acidic exhaust eat the mortar from inside. A chimney that leans or sheds brick onto the roof is a hazard to anyone walking below it.
Full removal or just the stack above the roof
$3,000 to $6,000
HomeGuide's national range for complete chimney and fireplace removal. A partial removal, usually the stack above the roofline, runs $500 to $2,500 in the same guide, and debris disposal $250 to $650.
Call (712) 543-5529Many owners take the chimney down below the roofline and patch the roof deck and shingles, leaving the lower part in the walls. That is the cheaper partial removal. A full removal takes out the chimney breast inside the house and the base in the basement, which frees floor space but involves interior repairs.
- Stack above the roof line: $800 to $2,000 (HomeGuide).
- Breast below the roof line: $1,500 to $2,500 (HomeGuide).
- Full chimney and fireplace: $3,000 to $6,000 (HomeGuide).
Flues, furnaces and what still uses the chimney
Before anything comes down, every appliance that might still vent into it is checked: an older furnace or water heater, a gas fireplace insert, a boiler. Removing a chimney that is still in use without rerouting the vent is dangerous. In an older house, the inside of the flue can also hold asbestos materials, which are tested before the crew opens it.
Permits and the roof afterwards
Removing part of a structure falls under Sioux City's demolition permit, which covers a building or any appendage or part of one, at an $85 base fee. Closing the roof opening is the second half of the job: decking, underlayment and shingles matched as closely as possible.
Brick, mortar and where the rubble goes
A chimney is mostly brick and mortar, and a tall one is heavier than it looks. Crews take it down by hand from the top, dropping the brick down the flue or into a chute rather than off the roof. Iowa DNR guidance allows clean brick, mortar and stone to be reused as fill when nothing else is mixed in, but inside Sioux City the grading rules decide what goes back into the ground, so most chimney rubble is trailered away.

Frequently asked questions
Chimney removal in Sioux City, answered
How much does chimney removal cost in Sioux City?
HomeGuide's national range is $3,000 to $6,000 for a complete chimney and fireplace removal, and $500 to $2,500 for a partial removal above or below the roofline.
What are the signs a chimney needs to come down?
Fallen brick, a lean, a cracked crown, water stains beside the chimney and no appliance still using it. Repointing can save a sound chimney, but a leaning or crumbling one is usually removed.
Is it cheaper to remove the chimney only above the roof?
Yes. Taking the stack down below the roofline and patching the roof is the low-cost option; removing the breast and base inside the house costs more but frees the space.
Do I need a permit to remove a chimney in Sioux City?
The city's demolition permit covers part of a structure as well as a whole building, at an $85 base fee. Ask Inspection Services or your contractor to confirm for your house.
What if my furnace still vents into the chimney?
Then the vent has to be rerouted, usually by an HVAC contractor, before the chimney is removed. Never take down a chimney that an appliance still uses.
