What affects the cost?
- Above-roofline (stack) vs. full-height rebuild — rebuilding just the visible stack above the roofline runs $1,500-$4,000, while a full rebuild from the foundation up averages $9,300 and can run $3,100-$15,400 (HomeAdvisor)
- Material — brick runs $60-$200 per linear foot, stone $80-$250, and metal $40-$120 (HomeAdvisor)
- Scaffolding and access — a small partial rebuild limited to the top few bricks 'is best for small chimneys that don't require scaffolding,' while larger or full rebuilds do, and scaffolding for chimney work generally adds $50-$200 (HomeAdvisor, Fixr)
- Extent of structural damage — fire damage, a leaning chimney, or extensive mortar deterioration can push a full rebuild past $20,000, versus an average $9,300 for a standard job (HomeAdvisor)
- Labor rate — chimney professionals charge $50-$150 per hour, plus many charge a flat $50-$100 service-call fee for smaller jobs (This Old House, Fixr)
- Real contractor bids vs. published estimates — Thumbtack's marketplace data shows rebricking the stack above the roof running $1,000-$3,500 and a full replacement $4,000-$15,000 (Thumbtack)
- Stack extension — adding height to meet code or improve ventilation runs $500-$3,000, a different job from repairing existing damage (HomeAdvisor)
- Real per-brick example — one contractor quoted $2,700 for a 300-brick rebuild including a new chimney crown and cap, or roughly $9 per brick installed (Thumbtack)
How much does it cost to rebuild a chimney?
A chimney rebuild runs $1,500 to $20,000 depending on how much of the structure needs replacing. Rebuilding just the stack — the visible portion above the roofline — costs $1,500 to $4,000, while a full rebuild from the foundation up averages $9,300, with a typical range of $3,100 to $15,400 (HomeAdvisor). For badly damaged chimneys — fire damage, a leaning stack, or extensive mortar deterioration — a full rebuild can exceed $20,000 (HomeAdvisor). Real contractor bids land close to those published figures: Thumbtack’s marketplace data shows homeowners paying $1,000 to $3,500 to rebrick the stack above the roof and $4,000 to $15,000 for a full replacement. That’s a much bigger job than a routine chimney repair, which covers common single-issue fixes like a cap, flashing, or mortar patch at a fraction of the price — a rebuild means removing and replacing brick, not just patching it.
What’s the difference between a stack rebuild and a full rebuild?
Scope and access. A stack rebuild replaces only the chimney’s above-roofline portion — the part exposed to weather and most prone to popping bricks or crumbling mortar — and HomeAdvisor notes it’s “best for small chimneys that don’t require scaffolding,” pricing it at $1,500 to $4,000. A full rebuild tears the chimney down to the foundation and reconstructs it entirely, which is why it averages more than double a stack job at $9,300 (range $3,100-$15,400, HomeAdvisor). Material drives the per-foot price either way: brick runs $60 to $200 per linear foot, stone $80 to $250, and metal $40 to $120 (HomeAdvisor) — stone typically costs more because it’s heavier and slower to set than brick. A related but distinct job is a stack extension, which adds height to an existing chimney to meet code or improve draft rather than replacing damaged material, and runs $500 to $3,000 (HomeAdvisor). Whichever scope applies, budget separately for a new chimney cap and chimney crown, since a rebuild typically doesn’t include replacing those components unless specifically scoped in.
When is repointing no longer enough, and a rebuild needed instead?
Once the damage has moved past the mortar joints and into the brick or structure itself. Repointing or tuckpointing — removing and replacing deteriorated mortar between intact bricks — runs $500 to $2,500 (Bob Vila, This Old House) and can extend a chimney’s life significantly, but it only works while the brick underneath is still sound. As Russ Dimmitt, director of education for the Chimney Safety Institute of America, puts it: “Some things that indicate repairs are needed are loose bricks or stone, or deteriorating mortar or bricks.” When those signs turn into leaning masonry or extensive brick deterioration rather than isolated cracks, This Old House notes a chimney “may require partial or complete rebuilding to restore its stability and safety” — mortar work alone can’t fix bricks that are cracked, spalling, or structurally compromised. A chimney inspection is the cheapest way to find out which side of that line your chimney is on before paying for either job.
Why do rebuild estimates vary, and how much does scaffolding add?
Scope definitions differ across sources, which explains why quoted ranges don’t all match. HomeAdvisor and Thumbtack separate above-roofline stack work ($1,500-$4,000 and $1,000-$3,500) from full-height rebuilds ($3,100-$15,400 and $4,000-$15,000), while Bob Vila and This Old House each publish one blended “rebuild” figure — $500-$4,000 and $500-$8,000 respectively — that mixes small partial jobs in with bigger ones. Access adds to the bill on top of scope: labor runs $50 to $150 per hour, with some contractors charging a flat $50-$100 service-call fee for smaller jobs (This Old House, Fixr), and scaffolding for chimney work generally adds another $50 to $200 (Fixr) since, as This Old House mason Mark McCullough notes, setting up safety staging for work above the roofline “can add significant time and cost” to a project. One real example illustrates per-brick pricing directly: a contractor quoted $2,700 for a 300-brick rebuild including a new crown and cap — about $9 per brick installed (Thumbtack).
Prices vary by region, chimney height, and how much of the structure is actually failing, so treat the figures above as a planning budget. Get a professional inspection and two or three rebuild quotes, confirming exactly how much of the chimney each contractor plans to remove and replace, before committing to a final number.

Frequently asked questions
How much does it cost to rebuild a chimney?+
A chimney rebuild costs $1,500 to $20,000. A full rebuild from the foundation up averages $9,300, with a typical range of $3,100 to $15,400 (HomeAdvisor); severely damaged chimneys can run past $20,000.
What's the difference between rebuilding the stack and a full rebuild?+
A stack rebuild replaces only the visible portion above the roofline and costs $1,500 to $4,000. A full rebuild replaces the chimney from the foundation up and averages $9,300, typically $3,100 to $15,400 (HomeAdvisor).
How much does chimney rebuild material cost per linear foot?+
Brick runs $60 to $200 per linear foot, stone $80 to $250, and metal $40 to $120 (HomeAdvisor) — material choice alone can more than triple the per-foot price.
When is repointing no longer enough, and a rebuild is needed instead?+
Once damage moves past the mortar joints and into the brick or structure itself. Signs include loose bricks or stone, deteriorating mortar or bricks (Bob Vila), or leaning masonry and extensive brick deterioration (This Old House) — repointing can't fix structural failure, only the joints.
Does a chimney rebuild need scaffolding?+
A small partial rebuild limited to a few bricks at the top typically doesn't (HomeAdvisor). Larger or full rebuilds usually do, adding roughly $50 to $200 to the project (Fixr).
How much does rebuilding a chimney stack cost versus extending it?+
Rebuilding an existing stack costs $1,500 to $4,000, similar to extending it for code or ventilation reasons, which runs $500 to $3,000 (HomeAdvisor) — extension adds height rather than replacing damaged material.
Do real contractor bids match published chimney rebuild estimates?+
Roughly, yes. Thumbtack's real marketplace bids show $1,000-$3,500 to rebrick the stack above the roof and $4,000-$15,000 for a full replacement — close to HomeAdvisor's published $1,500-$4,000 and $3,100-$15,400 figures.
Why do chimney rebuild cost estimates vary between sources?+
HomeAdvisor and Thumbtack separate above-roofline stack work from full-height rebuilds, while Bob Vila ($500-$4,000) and This Old House ($500-$8,000) publish a single blended 'rebuild' figure that mixes small partial jobs with larger ones, which is why their ranges look narrower or wider than HomeAdvisor's scope-specific numbers.
Sources
Figures synthesized and cross-checked across these sources (retrieved 2026-07-29):
- HomeAdvisor — Professional chimney replacement costs between $3,100 and $15,400, with an average of $9,300. Per linear foot by material: brick $60-$200, stone $80-$250, metal $40-$120. Stack rebuild (visible portion above the roofline): $1,500-$4,000. Stack extension (added height for code/ventilation): $500-$3,000. Full rebuild: averages $9,300; larger or more complex projects (fire damage, leaning chimney, extensive mortar deterioration) can exceed $20,000. Partial rebuild (top few bricks only, no scaffolding needed): about $1,500-$4,000. For comparison, chimney repair alone averages around $460.
- Bob Vila — Average chimney repair cost is $160-$750; average chimney rebuild costs $500-$4,000. Chimney stack repair $500-$3,500. Complete chimney restoration $250-$4,000. Repair-method costs: parging $1,000-$2,000, rebuilding $500-$4,000, remortaring $150-$500, repointing $500-$2,500, tuckpointing $500-$2,500, sealing $150-$500. Labor is dangerous and typically requires scaffolding for access. Quote from Russ Dimmitt, director of education for the Chimney Safety Institute of America (CSIA): 'Some things that indicate repairs are needed are loose bricks or stone, or deteriorating mortar or bricks.' Dimmitt also notes chimney work is 'best left to chimney professionals' due to fall-hazard and fire-safety risks.
- Fixr — Chimney rebuilding ranges from $500 to $4,000, depending on how much of the chimney requires reconstruction and overall chimney size. Scaffolding for chimney repair can add an extra $50 to $200. Labor costs range from $50 to $150 per hour, with many professionals charging a minimum fee of $50 to $100. Chimney rebuilding is seen as a last resort and only recommended when the chimney stack, crown, or foundation has suffered serious damage.
- This Old House — Chimney repair averages around $750, range $250-$13,300 depending on the type and extent of damage. By component: cap $100-$250, crown $750-$1,000, stack $500-$3,500, cricket $700-$1,300, flashing $200-$300, flue liner $200-$5,000, smoke chamber $500-$2,000, foundation $1,500-$3,000. By repair method: re-mortaring $150-$500, sealing $150-$500, restoring $250-$4,000, repointing $500-$2,500, tuckpointing $500-$2,500, rebuilding $500-$8,000, parging $1,000-$2,000. Labor $50-$150/hour; flat service-call fee $50-$100. Mason Mark McCullough notes that chimneys extending above the roofline often require ladders, scaffolding, or staging, which 'can add significant time and cost' to a project, and that 'water infiltration is always the biggest enemy to any chimney.' Rebuilding applies when a chimney has 'severe structural damage, like leaning masonry or extensive brick deterioration.'
- Thumbtack — National average chimney repair cost is $509-$1,821, most people pay around $965, according to Thumbtack data. For rebuilds: rebricking the stack above the roof runs $1,000-$3,500; full chimney replacement runs $4,000-$15,000. Real project example: Brothers Building Maintenance charged $2,700 for a 300-brick rebuild including a new chimney crown and cap.
HomeAdvisor draws the clearest above-roofline/full-height distinction: a stack rebuild (visible portion above the roofline only) runs $1,500-$4,000, while a full rebuild from the foundation up averages $9,300 with a normal range of $3,100-$15,400, and can exceed $20,000 for fire damage, a leaning chimney, or extensive mortar deterioration. Thumbtack's real marketplace bids corroborate both tiers with slightly lower figures: $1,000-$3,500 to rebrick the stack above the roof, and $4,000-$15,000 for a full replacement. Bob Vila and Fixr both cite a narrower, less scope-differentiated 'chimney rebuild' figure of $500-$4,000, and This Old House's by-repair-method table cites $500-$8,000 for 'rebuilding' generally — both likely blend small partial rebuilds (a handful of bricks) with larger jobs rather than separating above-roofline from full-height work the way HomeAdvisor and Thumbtack do. national_average_usd ($9,300) and project_low/high_usd ($3,100-$15,400) are anchored to HomeAdvisor's dedicated full-rebuild figures since it's the only source that prices a complete, foundation-up rebuild specifically rather than blending in smaller repairs. range_low_usd ($1,500) reflects the low end of an above-roofline stack rebuild (HomeAdvisor), and range_high_usd ($20,000) reflects HomeAdvisor's cited ceiling for a severely damaged full rebuild, giving the full realistic span from a small stack repair to a complete rebuild of a badly damaged chimney. Per-linear-foot material pricing (brick $60-$200, stone $80-$250, metal $40-$120) is HomeAdvisor's only, since other sources price rebuilds as flat project ranges rather than per linear foot. A rebuild is a materially different, more expensive job than repointing or tuckpointing, which run $500-$2,500 (Bob Vila, This Old House) or $4-$25 per sq ft (HomeGuide, per the repointing-specific cost record) for remortaring existing joints without removing brick; a rebuild becomes necessary once damage goes beyond the mortar joints into the brick or structure itself — loose bricks, deteriorating mortar or bricks, leaning masonry, or extensive brick deterioration (Bob Vila, This Old House). Figures generally include materials and standard labor for the portion being rebuilt; a new chimney crown and cap, flue liner, and permits are commonly quoted as separate line items on top of a rebuild.
