Chimney Repair Cost Estimate: 2026 Averages by Repair Type
A chimney repair cost estimate runs $455 on average for common 2026 jobs, with a typical range of $200 to $750. Larger projects span $900 to $15,000 depending on damage type. Tuckpointing runs $500 to $2,500, crown repair $200 to $3,000, liner replacement $900 to $7,000, and a full rebuild $4,000 to $15,000. Get a personalized number with our Chimney Repair Cost Calculator.
The pattern that drives chimney costs is delay. A minor $300 crown crack that is left through several freeze-thaw winters can spall the top courses of brick and turn into a four-figure partial rebuild, and an ignored stack can eventually require a $9,000 full rebuild. The cheapest bid is rarely the cheapest repair, because a sealed crown stops the water before it ever reaches the brick.
This is the data page, not the tool. Below you get the 2026 cost-by-repair-type tables, regional averages, and the diagnostic checklist that tells you whether you are looking at a $500 problem or a $10,000 one. When you are ready to price your own job by height and access, the chimney repair cost calculator does the math.
Chimney Repair Cost Estimate at a Glance
The single most important fact about chimney pricing: cost is driven by damage type, not chimney size. A six-foot decorative stack with a cracked liner can cost more than a 28-foot stack that only needs repointing. Match the repair to the symptom first, then price it.
| Repair Type | Typical Cost Range | Average | When You Need It |
|---|---|---|---|
| Flashing repair | $200 - $800 | $500 | Leaks at roof-chimney junction |
| Crown repair (minor) | $200 - $700 | $450 | Hairline cracks in top slab |
| Crown replacement | $1,000 - $3,000 | $2,000 | Widespread crown cracking |
| Tuckpointing | $500 - $2,500 | $1,200 | Mortar joints crumbling or missing |
| Spalling brick replacement | $25 - $100/brick | -- | Freeze-thaw brick flaking |
| Liner replacement | $900 - $7,000 | $2,500 | Cracked clay liner, gas conversion |
| Partial rebuild (top section) | $1,000 - $3,500 | $2,200 | Top-section spalling |
| Full rebuild | $4,000 - $15,000 | $9,000 | Leaning stack, structural cracks |

Tip
Before authorizing any bid over $1,500, pay for a Level 2 camera inspection ($250-$600). A 30-minute scope often settles whether you need a $1,200 tuckpoint or a $5,000 liner. That single visit can swing your estimate by $3,800 and stops contractors from quoting the worst case sight-unseen.
Tuckpointing Cost Estimate
Tuckpointing is grinding out failed mortar joints and repacking them with fresh, color-matched mortar. It is the most common masonry repair and the one that prevents the expensive ones. The national average is $1,200, with most jobs landing between $500 and $2,500 according to Angi.
Pricing is by joint area at $10 to $25 per square foot. A typical residential chimney has 40 to 100 square feet of exposed joint depending on height and how many sides are visible.
| Joint Area | Rate (per sqft) | Estimated Cost |
|---|---|---|
| 40 sqft (single-story, 2 sides exposed) | $15 | $600 |
| 60 sqft (single-story, all sides) | $18 | $1,080 |
| 80 sqft (two-story, 2 sides exposed) | $20 | $1,600 |
| 100 sqft (two-story, all sides) | $22 | $2,200 |
Each row reconciles as area multiplied by rate: 40 x $15 = $600, 60 x $18 = $1,080, 80 x $20 = $1,600, 100 x $22 = $2,200. The rate climbs with height because two-story work needs scaffolding and the per-square-foot labor rises with access difficulty.
Warning
Ignoring crumbling mortar is the most expensive mistake in chimney ownership. Open joints let water in, water freezes and expands, and freeze-thaw cycles pop the brick faces off (spalling). A $1,200 tuckpoint skipped for several winters can escalate into a $1,000 to $3,500 partial rebuild once the top courses spall. Repointing early is the single best way to avoid that jump.
Chimney Liner Replacement Cost Estimate
The flue liner is the most expensive single line item on most chimneys because the material is priced per foot and the labor is awkward. A new liner runs $900 to $7,000 installed, with stainless steel relines landing $900 to $3,800 on a standard residential flue per HomeGuide.
| Liner Material | Cost per Foot | 24 ft Flue (material) | Typical Installed Total |
|---|---|---|---|
| Aluminum (gas only) | $6 - $15 | $144 - $360 | $900 - $1,800 |
| Rigid stainless | $20 - $40 | $480 - $960 | $1,800 - $3,500 |
| Flexible stainless | $40 - $90 | $960 - $2,160 | $2,500 - $5,000 |
| Cast-in-place | $90 - $120 | $2,160 - $2,880 | $4,000 - $7,000 |
Material totals are per-foot rate times a 24-foot flue: rigid stainless at $20-$40 gives $480-$960, flexible at $40-$90 gives $960-$2,160. Installed totals add $800 to $1,500 in labor plus a top cap, and removal of an old clay liner adds $500 to $2,500 on its own.
A failed clay liner or a wood-to-gas conversion is the usual trigger. Any vertical crack in a liner is a safety issue, not a cosmetic one, because combustion gases can leak into the wall cavity. If your repair is paired with shingle work where the liner meets the roof, price the matching job with our Roof Repair Cost Calculator.
Chimney Crown and Flashing Cost Estimate
The crown is the concrete slab on top of the chimney that sheds water away from the flue. The flashing is the metal seal where the chimney passes through the roof. Together they are the two most common water-entry points, and both are cheap to fix early.
| Component | Repair Scope | Cost Range |
|---|---|---|
| Crown | Seal hairline cracks | $200 - $500 |
| Crown | Patch and waterproof | $400 - $700 |
| Crown | Tear off and re-pour | $1,000 - $3,000 |
| Flashing | Re-seal existing | $200 - $400 |
| Flashing | New step + counter flashing | $400 - $800 |
A ceiling stain in the room directly below a chimney almost always traces to flashing, not the roof field. Fix it for $200 to $800 before the water rots the framing. The Roof Pitch Calculator matters here too: a pitch over 6/12 adds 15 to 25 percent to any roof-line chimney work because the crew needs fall protection.
Important
A cracked crown is the cheapest repair to ignore and the most expensive consequence. Water that gets past a $400 crown patch attacks the mortar, the brick, and eventually the liner. Sealing the crown is the single highest-return maintenance dollar on a masonry chimney.
Chimney Rebuild Cost Estimate
When repair is no longer enough, you are into rebuild territory. A partial rebuild covers the top few feet; a full rebuild is a structural teardown.
| Rebuild Type | Cost Range | Per Linear Foot | Trigger |
|---|---|---|---|
| Partial (top 5-10 ft brick) | $1,000 - $3,500 | $200 - $350 | Spalling top courses below the crown |
| Stack rebuild (above roofline) | $1,000 - $3,500 | $100 - $300 | Spalling above the roof, sound base |
| Stone stack rebuild | $1,600 - $5,000 | $80 - $250 | Stone masonry above roofline |
| Full rebuild (above + below) | $4,000 - $15,000 | $100 - $300 | Leaning, structural cracking |
Each per-foot rate reconciles against the total at the band endpoints. A partial rebuild of 5 feet at $200 per linear foot is $1,000, and 10 feet at $350 is $3,500. A 10-foot brick stack above the roofline at $150 per linear foot prices to $1,500, which sits squarely in the stack-rebuild band, and a 20-foot stone stack at $80 to $250 spans $1,600 to $5,000. A full rebuild that includes the firebox and the run inside the house is where you cross $5,000 and often climb to $15,000 per Angi rebuild data and HomeGuide.
There is a fourth option contractors rarely volunteer: removal. If the chimney is decorative and serves no working fireplace, removal costs $2,000 to $6,000 and ends the maintenance liability permanently. On a mid-century home where the fireplace has been dark for 20 years, removal beats a $9,000 rebuild every time. Ask about it before you authorize anything over $5,000.
Chimney Inspection Cost Estimate
You cannot price a repair you have not diagnosed. Both the Chimney Safety Institute of America (CSIA) and the NFPA recommend annual inspection, and three standardized levels exist.
| Inspection Level | Cost | What It Covers |
|---|---|---|
| Level 1 | $100 - $250 | Visual check of accessible interior and exterior |
| Level 2 | $250 - $600 | Level 1 plus internal video camera scan |
| Level 3 | $1,000+ | Tear-into-walls for suspected hidden structural damage |
Level 1 suits a chimney in regular use with no known issues. Level 2 is required after any chimney fire, before a real estate sale, or when you change fuel systems. Level 3 is reserved for a suspected hidden structural problem. Always hire a CSIA-certified, NCSG, or NFI-credentialed contractor, and get the inspection report in writing before any work is authorized.
How Access and Urgency Change Your Estimate
The same repair on two different houses can differ by 40 percent because of access and timing. These surcharges stack on top of the base repair cost.
| Factor | Surcharge | Why |
|---|---|---|
| Two-story height | +20% to +30% | Scaffolding, fall protection, longer hauls |
| Roof pitch over 6/12 | +15% to +25% | Steep-access safety gear |
| Scaffolding rental | +$200 to $600 | Required for high or steep stacks |
| Permit | up to $300 | Structural rebuilds and liner work |
| Emergency / post-fire | +20% to +40% | Off-schedule crew, urgent water intrusion |
Worked example: a $1,500 base crown-and-flashing repair on a two-story home with a 7/12 pitch picks up roughly a 25 percent access surcharge ($375) plus a $400 scaffold rental, landing near $2,275. That reconciles as $1,500 + $375 + $400 = $2,275. Run your own height and access combination through the chimney repair cost calculator to see the surcharge applied automatically.
Tip
Bundle chimney flashing with a re-roof if both are due. Crews already on the roof can redo flashing for a fraction of a standalone trip charge, and you can often negotiate a 5 to 10 percent bundle discount. If you are planning a re-roof, see how much a new roof costs in 2026 before scheduling the chimney work.
Frequently Asked Questions
How much does chimney tuckpointing cost?
Tuckpointing runs $500 to $2,500, with a national average near $1,200. Pricing is by exposed joint area at $10 to $25 per square foot, so a 40-square-foot single-story job at $15 is about $600, while a 100-square-foot two-story chimney at $22 reaches $2,200. Two-story work costs more because it needs scaffolding and steep-access labor.
Chimney repair cost estimate
A chimney repair cost estimate averages $455 for common 2026 jobs and ranges from $200 to $750, while larger projects span $900 to $15,000. Tuckpointing runs $500 to $2,500, crown repair $200 to $3,000, liner replacement $900 to $7,000, and a full rebuild $4,000 to $15,000.
When does a chimney need a full rebuild instead of a repair?
A full rebuild is warranted when the stack leans, shows structural cracking, or has spalling that runs below the roofline into the load-bearing section. At that point repointing or a partial rebuild only buys time. A full rebuild runs $4,000 to $15,000 depending on height and whether the firebox and interior run are included, versus $1,000 to $3,500 for a partial top-section rebuild. A Level 2 or Level 3 inspection should confirm the call before you authorize a teardown.
How much does a new chimney liner cost?
A new flue liner runs $900 to $7,000 installed. Stainless steel relines on a standard 24-foot residential flue typically land $1,800 to $5,000, with rigid stainless on the lower end and flexible or cast-in-place at the top. Material is priced per foot, and labor adds $800 to $1,500 plus a top cap; removing an old clay liner can add $500 to $2,500 on its own.
Roof leak repair cost estimate
A roof leak repair estimate runs $400 to $1,700 in 2026, and chimney flashing is one of the most common leak sources, costing $200 to $800 to re-seal. A stain on the ceiling directly below a chimney almost always traces to failed flashing rather than the roof field, so price the flashing first.
Does homeowners insurance cover chimney repair?
Insurance covers sudden damage such as a chimney fire, lightning strike, or a fallen tree, but not wear-and-tear, settling cracks, or creosote neglect. Document the cause with photos and a CSIA inspection report before filing a claim, because the report is what separates a covered event from excluded maintenance.
What is a fair deposit for chimney repair?
Reputable masons cap deposits at 10 to 25 percent of the project, and jobs under $1,000 are often paid on completion with no deposit at all. Any demand for 50 percent or more upfront, or a cash-only request, is a classic scam signal in the chimney trade. Pay by card or check for fraud protection and walk away from pressure.
