Nothing gives a home old-school charm like a chimney, and maintaining it is essential if you want to spend those cold winter nights in front of a toasty fire with the family. But when a chimney is cracked, crumbling, or otherwise damaged, it can dampen the mood—not to mention prompt anxious questions from the kids about how Santa Claus is going to get inside when Christmas rolls around. 

Standard costs for a partial rebuild of the average chimney run between $1,000 and $3,000—and up to $5,000 or more if the chimney is particularly large or has a complex design.

If you need to replace the whole thing before you can throw another log on the fire, expect costs to rise to around $10,000.

How Much Does It Cost to Rebuild by Part?

The ultimate tally for your chimney rebuild will depend on which parts need to be reconstructed. 

Chimney Stack

Rebuilding the chimney stack—the portion that extends from your roofline—costs, on average, $150 per linear foot. If the damage to your existing stack is relatively minor, this rate should only apply to the sections that need to be rebuilt. 

If the whole stack needs to be removed and replaced, expect to pay an additional $1,000 to $1,600 for hauling and disposal. Also worth noting: These rates assume the job will require scaffolding—if the top of your stack is accessible via ladder, you will pay a little less.

Fireplace

Average costs to rebuild or remodel a fireplace run between $390 and $2,000. Whether yours is at the lower or higher end of that range will depend on the size of the fireplace and the materials used (the least expensive option being recycled stone or brick). 

If it’s a prefabricated fireplace, average removal costs will fall between $600 and $2,500, plus anywhere between $700 and $7,2000 for a new prefab model, depending on the type. 

Full Chimney Replacement

If the chimney is so thoroughly damaged that a complete do-over is necessary, costs rise significantly. Expect to pay around $10,000 for most replacements. The total charge can vary significantly, though, depending on the type and extent of the damage, so don’t hesitate to contact local chimney repair contractors for quotes. 

How Much Does It Cost to Rebuild a Chimney Yourself?

Like many other roof projects—and any jobs requiring a tall ladder—there are serious risks involved in a chimney rebuild, and we do not recommend a DIY approach. Even beyond the immediate risks, chimney repair is complicated work that requires specialized knowledge, and an improperly installed chimney can pose serious dangers to your household. A damaged chimney requires professional attention, so call an area masonry contractor.

How Much Does It Cost to Rebuild a Chimney by Type?

  • Wood-burning: $3,500–$5,300

  • Gas: $5,000–$7,200

  • Stone: $4,500–$6,400

  • Electric: $700–$4,700

Which Factors Influence the Cost of a Chimney Rebuild?

The final cost of your chimney rebuild will be affected by a few primary factors: 

Size

The biggest factor influencing the cost of your rebuild will be the size of the chimney or the portion that requires repair. The more you need to rebuild, the more costs rise.

Height and Position

In most cases, if the chimney stack needs to be rebuilt, the masonry professionals who do the job will need to use scaffolding to work safely, adding to your costs. If the top of your chimney is low enough to reach by ladder, most masons will offer a reduced rate per square foot. 

Extent and Location of the Damage

In most cases, if the chimney stack needs to be rebuilt, the masonry professionals who do the job will need to use scaffolding to work safely, adding to your costs. If the top of your chimney is low enough to reach by ladder, most masons will offer a reduced rate per square foot. 

Extent and Location of the Damage

The majority of rebuilds only need to touch the exterior layer of bricks that form the chimney’s wall or show-course. In rarer cases, the damage might extend to the liner bricks or even the flue, likely entailing a full replacement or a significantly more expensive rebuild. 

Likewise, different kinds of damage can result in more or less complex rebuilds. If you’re dealing with fire damage, for example, expect higher costs. 

FAQs About Chimney Rebuilds

How much does it cost to repair a chimney? 

Not every problem with your chimney requires a rebuild. Small cracks, issues with the crown or flue, and leaks can often be fixed through less extensive repairs. 

Average costs for chimney repairs run between $160 and $750 and can climb as high as $1,800. For ongoing maintenance, the average cost of a chimney sweep is between $130 and $380. 

What causes a chimney to crack?

Poor construction can lead to cracking from the chimney’s normal expansion and contraction when it’s heated up or cooled down. Moisture is also a common culprit, creeping into the tiny pores of mortar and brick that haven’t been properly sealed. 

Additionally, if the chimney’s footing isn’t solid, the stack can start to lean, ultimately causing cracks. Many other types of cracks are the inevitable result of the trials that Mother Nature puts the chimney through over time. 

Many chimney cracks can be treated as minor maintenance issues, while others can pose more serious problems. Inspect—or hire an inspector—to look at any new cracks that emerge, since the sooner you catch them, the easier (and less expensive) it will be to solve the problem. 

When should I replace my chimney?

Like other kinds of masonry and brickwork, a properly installed chimney should have a lifespan that extends beyond multiple generations of homeowners. But there are parts of the chimney that will need to be replaced more frequently. 

  • Clay tile or cast-in-place liners should be replaced every 50 years

  • Stainless steel liners will last an average of 15–20 years

  • Mortar will require replacement every 25–30 years

  • Chimney crowns have an average lifespan of 50–75 years
