Chimney Repair Cost
Chimney repair costs $200–$850 for common fixes like caps and crown patches — up to $15,000 for a full rebuild. Price your specific repair, from flashing leaks to liner replacement, with inspection and permit costs included.
Your number depends on which specific fix the chimney needs — a cap swap and a rebuild share a page but not a price league — plus whether a pro still has to diagnose it. Tall chimneys, steep roofs, and hard access push any repair toward the top of its range.
Where's the problem?
Chimney repairs sort by location: the cap and crown up top take the weather first, the brick and mortar weather next, leaks show up where chimney meets roof, the flue is the fire-safety interior, and leaning or crumbling structure is its own category. Pick the closest match — the specific fixes appear below.
What needs fixing?
Each repair carries its own market band. If you're not sure which one you need, that's what the inspection is for — pick your best guess and toggle the inspection on below.
Has a pro diagnosed it yet?
Most chimney repairs start with a professional inspection — it catches the problems you can't see from the ground and turns a guess into a scope of work. A basic inspection runs $100–$300; structural assessments can exceed $1,000.

Why the small fix is the cheap insurance
Water is a chimney's biggest enemy, and every one of these repairs is really a water story: a missing cap lets rain straight down the flue, a cracked crown wicks it into the brick, and failed mortar lets freeze-thaw cycles pry the masonry apart. Today's few-hundred-dollar fix is what stands between you and the thousand-dollar tier — and unrepaired damage is exactly what insurance won't cover later.
Chimney work is certification territory
Hire pros certified by the Chimney Safety Institute of America (CSIA) or National Chimney Sweep Guild — a chimney done wrong is a fire hazard or a carbon monoxide path, not a cosmetic miss. If damage came from a storm, lightning, a fallen tree, or a chimney fire, photograph everything first: those are the cases homeowners insurance typically covers (wear and tear is not).
Chimney pros run $50–$200/hour (up to $300 for emergency calls), and taller or harder-to-reach chimneys cost more to scaffold and repair. Repair tiers: minor $200–$850, moderate $500–$2,500, major $1,000–$7,000, full rebuild $4,000–$15,000. Stucco chimneys skew high ($900–$4,000 for typical repairs) because the finish must be matched. Several bands are open-ended — crown repair, parging, and partial rebuilds can exceed their tops on tall or badly damaged chimneys.
💡About this calculator▼
Chimney repair is really a dozen different repairs sharing one word, and the price depends entirely on which one you need: the common fixes — a new cap, a crown patch, small cracks — run $200 to $850, while the ladder climbs through repointing and flashing ($500–$2,500 territory), liner replacement and structural work ($1,000–$7,000), and tops out at a full rebuild at $4,000–$15,000.
The good news buried in that spread: most chimney problems announce themselves cheap. Nearly everything on the expensive end starts as something on the cheap end — a missing cap lets rain down the flue, a cracked crown wicks water into the brick, failed mortar gives freeze-thaw cycles something to pry apart. Which is why the smart money treats the small repairs as urgent and the big ones as decisions.
This calculator works like the diagnosis: point at where the problem lives — the top, the brick, the roofline, the flue interior, or the structure itself — then pick the specific fix. If you don't know yet, that's normal: most repairs start with a professional inspection ($100–$300), and there's a toggle to include one. Permits join automatically on the structural jobs that need them.
One boundary worth knowing: this page prices fixing the chimney. Routine sweeping and annual inspections have their own page, and deep mortar restoration on larger brick surfaces has its own too — both linked below.
The repair type is the price. Everything else nudges it.
The ladder. Chimney repairs cluster into four published tiers: minor ($200–$850 — caps, minor crown repairs, small cracks), moderate ($500–$2,500 — repointing, waterproofing, flashing), major ($1,000–$7,000 — liner replacement and structural fixes), and extensive rebuilds at $4,000–$15,000. Each specific repair carries its own band inside those tiers, and the calculator uses the specific bands: a cap replacement is $200–$850, flashing repair $300–$1,800, a full liner $1,500–$7,000, stabilizing a leaning chimney $2,000–$4,000.
The diagnosis. Most repairs start with a professional inspection at $100–$300 — it finds the problems invisible from the ground and turns "the chimney looks rough" into a scope of work. Comprehensive structural assessments can exceed $1,000. The calculator adds the basic inspection when you toggle it on.
The adders. Some major repairs need building permits at $50–$200 — the calculator includes them automatically on liner replacements, leaning-chimney work, and rebuilds. Beyond that, labor runs $50–$200 per hour (up to $300 for emergency calls), and the two big unpriced variables are height and access: a three-story chimney over a steep roof costs meaningfully more to scaffold and repair than a single-story one an extension ladder reaches.
📐How it's calculated▼
Total = your specific repair + inspection (if still needed) + permit (on structural jobs).
Repair bands, verbatim from the published type pricing: cap replacement $200–$850 · crown repair $200–$700 · crown replacement $1,000–$3,000 · small crack repairs $150–$500 · flashing repair $300–$1,800 · sealing & waterproofing $150–$820 · a few cracked flue tiles $200–$400 · liner replacement $1,500–$7,000 · smoke chamber parging $800–$2,000 · repointing $500–$2,500 · spalling brick repair $1,000–$3,500 · leaning chimney $2,000–$4,000 · partial rebuild $1,000–$5,000 · full rebuild or replacement $4,000–$15,000.
Inspection: $100–$300 for a basic professional inspection; structural assessments can exceed $1,000.
Permits: $50–$200, included automatically on liner replacements, leaning-chimney stabilization, and partial or full rebuilds.
Context for the bands: labor is $50–$200 per hour and dominates most of these jobs — repointing is about 90% labor — and several bands are published open-ended, so tall or badly damaged chimneys can exceed their tops.
🔍Finding your inputs▼
Where's the problem? Chimneys fail from the top down and the outside in, so location is the first diagnosis. Rain, rust, or critters getting in points to the top (cap or crown). Visible cracks, crumbling joints, or flaking brick faces are the masonry. Water stains on the ceiling or walls near the chimney are almost always the roofline flashing. Smoke problems, draft issues, or an inspector's note about tiles mean the flue. And any visible lean or separation from the house is structural — the drop-everything category.
What needs fixing? The cards narrow to your area's repairs, each with its own market band. Pick your best guess — the descriptions say what each fix actually is. If two seem plausible (crown repair vs. crown replacement, spot tiles vs. full liner), price both: the gap between them is exactly what the inspection visit settles.
Has a pro diagnosed it yet? If you're working from your own observation, toggle the inspection on — most repairs start with one, it runs $100–$300, and it routinely finds the second problem hiding behind the first. If a sweep or inspector already handed you a report, leave it off and price the repair alone.
⚠️Special situations▼
My chimney is leaning — how urgent is this really?
Genuinely urgent — a leaning chimney is a structural problem, not a cosmetic one, and the causes (foundation settling, eroded mortar, shifting soil) all get worse on their own. Stabilization runs $2,000–$4,000, but severe cases involving foundation damage need helical piers and climb from there, and a significant lean can force a full rebuild. Get a certified pro out promptly, and if the lean traces to the foundation itself, that's a separate repair with its own page linked below.
The inspector says I need a new liner. Is that the $200 fix or the $7,000 one?
Depends on how much of it failed. A few cracked clay tiles can be spot-repaired for $200–$400 — that's the cheap outcome. Cracking throughout the flue means a full liner replacement at $1,500–$7,000, with the spread set by material (stainless steel vs. cast-in-place) and chimney height. This one isn't optional either way: the liner is what keeps heat and carbon monoxide out of your walls, which is why it's also one of the repairs that pulls a permit.
Water stains on the ceiling near the chimney — is that a chimney repair or a roof repair?
Usually the seam between them: flashing — the metal where chimney meets roof — is the classic culprit, and repairing it runs $300–$1,800 depending on chimney size, material, and access. Start with a chimney or roofing pro inspecting the flashing before assuming worse. If the leak has been running a while, budget for what it fed: interior staining, and in bad cases mold or rot, which are their own repairs beyond this estimate.
Can I do any of this myself?
Very little, honestly. Applying waterproof sealant is about the only DIY-friendly item on the list — everything else combines work at height with fire-and-carbon-monoxide consequences for getting it wrong. Structural repairs, liner work, and repointing belong with certified professionals. The DIY contribution that actually pays: catching problems early from the ground (binoculars on the crown and cap each spring) and keeping the annual inspection habit, which is the cheapest line on this whole page.
Will homeowners insurance pay for this?
Only if a covered event caused it: lightning, severe storms, a fallen tree, or an unexpected chimney fire are claimable; gradual wear, freeze-thaw deterioration, and deferred maintenance are not. Two practical moves: photograph storm damage before any repair work starts, and don't sit on known damage — insurers typically won't cover the rot and mold that follow a leak you knew about. Check your policy's specifics before assuming either way.
❓Common questions▼
How much does chimney repair cost?
Chimney repair costs $200–$850 for the common fixes — cap replacement, minor crown repairs, small cracks. Moderate work like repointing, waterproofing, and flashing repair runs $500–$2,500; major repairs like liner replacement and structural fixes run $1,000–$7,000; and a full rebuild or replacement costs $4,000–$15,000. A professional inspection to diagnose the problem adds $100–$300, and permits on major work add $50–$200.
How much does it cost to fix the top of a chimney?
The top is the cheap end of chimney repair: replacing the cap — the metal cover that keeps rain, debris, and animals out — costs $200–$850 installed, and patching cracks in the crown (the concrete slab under it) runs $200–$700. A crown too far gone to patch costs $1,000–$3,000 to replace. These are also the repairs most worth doing promptly, since both parts exist to keep water out of everything below them.
How much does a chimney rebuild cost?
A partial rebuild — tearing down and relaying the damaged section, often from the roofline up — costs $1,000–$5,000. A complete rebuild or replacement runs $4,000–$15,000. Rebuilding beats repairing when damage is chimney-wide: widespread spalling, mortar failing throughout, a significant lean, full-height cracks, fire damage, or repair quotes reaching half the cost of replacement. The consolation: a new chimney lasts 50 to 100+ years.
Why is my chimney leaking when it rains?
The usual suspects, in order: damaged flashing where the chimney meets the roof ($300–$1,800 to repair), a missing or damaged cap letting rain straight down the flue ($200–$850), a cracked crown wicking water into the masonry ($200–$700 to patch), or porous, deteriorating brick that needs sealing ($150–$500) or full waterproofing. An inspection sorts out which — and matters, because a chimney leak left running feeds mold, rot, and interior damage well beyond the chimney itself.
How often should a chimney be inspected?
Annually — that's the National Fire Protection Association's recommendation, with a cleaning as needed based on what the inspection finds. A basic inspection runs $100–$300 and is the cheapest item in the entire chimney budget: it catches the $200 problems before they compound into the $2,000 ones, keeps creosote from reaching chimney-fire levels, and spots the flue cracks that turn into carbon monoxide paths. Skipping it is how chimneys end up on the expensive half of this page.
Who should I hire to repair a chimney?
Look for certification from the Chimney Safety Institute of America (CSIA) or membership in the National Chimney Sweep Guild — chimney work done wrong creates fire and carbon monoxide hazards, not just cosmetic problems. Get at least three written estimates, verify licensing and insurance, and ask each pro to specify the scope: which repairs, which materials, what warranty on parts and labor, and who handles the permit when the job needs one.
