Chimney rebuild cost

Updated October 2, 2026 · Every figure checked twice against its source · How we verify

A chimney rebuild costs $1,000 to $3,500 to rebrick the stack above the roofline, according to HomeGuide's chimney rebuild cost guide; a partial rebuild of the top few feet costs $600 to $1,000, and a complete replacement above and below the roofline costs $4,000 to $15,000. HomeGuide puts the national average at $2,200. Fixr gives a single range of $500 to $4,000 for rebuilding sections of a chimney. HomeGuide says the chimney crown and cap are replaced in all three types of rebuild.

How much does it cost to rebuild a chimney?

HomeGuide's chimney rebuild guide gives a national average cost of $2,200, a minimum of $600, a maximum of $15,000 and an average range of $1,000 to $5,000. Its three price bands follow how much of the chimney is rebuilt: the top few feet, the whole stack above the roof, or the chimney above and below the roofline.

The price guides do not all label these jobs the same way, so compare the work described, not the name on the quote:

HomeGuide's two guides disagree on what "complete rebuild" means. Its rebuild guide uses the term for the $1,000 to $3,500 roofline up job and calls the $4,000 to $15,000 job a complete replacement. Its repair guide uses "complete chimney rebuild or replacement" for the $4,000 to $15,000 job and puts partial rebuilds at $1,000 to $5,000+. Fixr says the cost of a rebuild depends on how much of the chimney needs to be rebuilt and the chimney size, and that small rebuilds can be done quickly and inexpensively while extensive rebuilds cost much more.

Cost to rebuild chimney above roof

HomeGuide says a complete chimney stack rebuild costs $1,000 to $3,500, or $100 to $300 per linear foot from above the roof to the crown for a single flue and $200 to $400 per linear foot for a double flue. It lists what moves that price: chimney size, roof accessibility, scaffolding, level of deterioration, materials, design details such as corbelling or shadowing, additional repairs, and labor.

According to HomeGuide, a complete rebuild from the roofline up includes scaffolding and replacing any damaged flashing. It says professionals match the color and consistency of the existing mortar and bricks and try to reuse any bricks that are still in good condition. HomeGuide also says that usually only the outside bricks, the show courses, have to be replaced when significant deterioration occurs and repointing is insufficient, and that the top part of a chimney degrades first, especially without repointing and resealing the joints every five years.

If the stack also needs more height, HomeGuide prices a chimney extension, which adds a few feet of height for proper ventilation, to meet building codes or to keep embers from escaping, at $1,000 to $3,000 on average: $1,000 for metal and $3,000 for masonry.

Partial chimney rebuild

HomeGuide recommends a partial rebuild when only a few bricks are cracked, missing, or crumbling (spalling). At $600 to $1,000, it covers a full small chimney or the top few feet or courses of a large chimney above the roofline, done without scaffolding. HomeGuide gives the same $600 to $1,000 for replacing the top few feet of bricks and repairing the crown.

HomeGuide's roofline up rebuild is for significant deterioration: vertical cracking, spalling bricks and damaged mortar joints, where it says the whole stack must be torn down and rebuilt from the roofline up. For a leaning chimney, Fixr says helical piers usually need to be installed for extra support, or it may require a partial rebuild, and it puts leaning chimney repairs at $1,500 to $3,500.

Full chimney replacement cost

HomeGuide says a chimney replacement costs $4,000 to $15,000 to rebuild above and below the roofline, and is required when there is structural damage throughout that cracks the mortar. It prices metal chimney replacement at $5,000 to $10,000 and masonry at $4,000 to $15,000. Typically, it says, the firebox, smoke chamber and hearth remain intact.

HomeGuide lists these possible additional costs for chimney construction:

• A new concrete pad or chimney foundation
• A new hearth, mantel or smoke chamber
• A new chimney liner, at $1,500 to $4,000
• Damper installation
• Permits and inspections

HomeGuide's repair guide says some major repairs require building permits, adding $50 to $200, and that the contractor usually handles the permit application. Fixr says a permit may be needed, especially for rebuilding or adjusting the brickwork and masonry, and to check with the local building authority before starting. On the long-term case, HomeGuide's repair guide says a complete rebuild or replacement may be more economical than repeatedly repairing a deteriorating chimney, and that a new chimney can last 50 to 100+ years with proper maintenance.

When do you need to rebuild a chimney?

HomeGuide says a chimney needs to be rebuilt when it is severely cracked and crumbling, spalling, leaning, deteriorating, or no longer structurally sound. Its rebuild guide lists these signs:

• Vertical cracking in the chimney stack
• Damaged, cracked, or uneven areas of mortar
• Chipped, cracked, missing, crumbling, or spalling bricks
• A crumbling, cracked, or missing chimney crown
• Cracked flue tiles
• An old chimney missing a liner, with the interior coated in thick creosote
• A leaning stack with eroded mortar joints
• Water damage posing a structural risk

HomeGuide's repair guide also lists, as reasons to consider rebuilding, fire damage that has weakened the chimney structure, a failing or damaged foundation, an older chimney that has been repeatedly patched, and repair costs that approach 50% or more of replacement costs. Fixr calls rebuilding a last resort, only recommended when the chimney stack, crown, or foundation has suffered serious damage. HomeGuide's chimney crown guide says that if a faulty crown goes without repairs for too long, the entire chimney may need to be rebuilt; our chimney crown repair guide covers that job.

Fire damage is the case CSIA addresses. The Chimney Safety Institute of America (CSIA) says a chimney fire in a masonry chimney burns at around 2000°F and can melt mortar, crack tiles, cause liners to collapse and damage the outer masonry. After a suspected chimney fire, CSIA says to call a CSIA Certified Chimney Sweep for an evaluation, and that depending on the situation you might need a few flue tiles replaced, a new liner system installed or an entire chimney rebuilt.

HomeGuide says to hire a chimney sweep or structural engineer to inspect and determine whether the chimney needs rebuilding. Its repair guide puts a basic chimney inspection at $100 to $300 and says more comprehensive inspections for structural damage can exceed $1,000.

Repointing vs rebuilding brick chimney

HomeGuide says damaged masonry chimneys that are still structurally sound can be repaired, and stacks that have collapsed or are beyond repair can be removed and completely replaced. Its repair prices for the work short of a rebuild:

HomeGuide says repointing repairs crumbling and damaged mortar joints to help support a stack that is still structurally secure, and does not work if the chimney damage is substantial. Fixr puts repointing at $500 to $2,500, the same range as HomeGuide's rebuild guide. HomeGuide's repair guide differs: its cost table lists repointing and tuckpointing at $500 to $2,500, but its repointing section says repointing costs $700 to $3,000 for most chimney projects.

HomeGuide says a severely damaged chimney stack that is unused can be removed to reclaim wasted space, and prices removing everything above the roofline at $800 to $2,000. See our chimney removal cost guide.

What the 2021 IRC requires of a masonry chimney

HomeGuide says chimneys must meet building code requirements to pass inspection, including the right height, wall thickness and clearance from combustibles. In the 2021 International Residential Code, these sections of chapter 10 set the height, cap, lining and roof cricket of a masonry chimney. They bind only where your jurisdiction has adopted that edition; Fixr says to check with the local building authority before starting chimney repairs.

In our reading, the code's "cap" in R1003.9.1 is the sloped top slab that HomeGuide and CSIA call the crown; neither source states that equivalence itself. Liner options and prices are in our chimney liner cost guide.

Getting chimney rebuild quotes

HomeGuide suggests getting at least three in-person estimates, choosing CSIA certified companies that are insured and bonded, asking for a written contract and warranty, and not paying large amounts upfront. It suggests asking each contractor:

• Will you obtain a structural engineer's report?
• Will you pull any necessary permits?
• Are scaffolding, debris disposal and cleanup included in your estimate?
• Will you fix any roof damage after the stack is rebuilt?
