How Much Does Chimney Replacement Cost? [2026 Data]

In 2026, the national average cost for chimney replacement is $9,300. Most homeowners spend between $3,100 and $15,400, with final costs driven by chimney height, materials, and overall chimney type.

What Are Chimney Replacement Costs by Project Scope?

The scope of your chimney project—whether a partial rebuild or a complete chimney rebuild—is the primary driver of total cost. Taller chimneys of 10 feet or more require additional materials and labor, which pushes costs higher. Getting a professional assessment before finalizing your scope helps you avoid unexpected expenses mid-project.

Full Chimney Replacement

A full chimney removal and replacement costs more than $5,000, and extensive rebuilding projects can reach upward of $20,000. This level of work is typically necessary when a chimney is leaning, crumbling, or otherwise too damaged to repair safely.

Partial Chimney Rebuild

A partial chimney rebuild costs about $1,500 to $4,000, making it a more budget-friendly alternative to a full replacement. This type of reconstruction typically involves rebuilding the chimney stack from the roofline upward, leaving the lower structure intact.

Chimney Extension

Extending your chimney costs about $500 to $3,000, with the need typically driven by inadequate ventilation or local building code requirements. The final cost depends on how much height must be added and the materials used to match your existing chimney.

How Do Materials Affect Chimney Replacement Costs?

Material selection is one of the most significant factors in chimney repair costs, directly affecting both your per-linear-foot rate (from $40 to $250) and your total project budget. The sections below break down replacement costs for the most common chimney materials so you can compare options before committing to a choice.

Here is a summary of average chimney replacement costs by material in 2026:

Brick

Replacing bricks costs $60 to $200 per linear foot, making it a mid-range material choice for chimney replacement. Adding a brick fireplace alongside the chimney work requires an extra $2,000 to $5,000, depending on the design and size you choose.

Stone

Stone is the most expensive common chimney material, with replacement costs ranging from $80 to $250 per linear foot. Any stone fireplace additions will add further to the total, so factor those costs into your budget before selecting this material.

Metal

Metal is the most affordable chimney material, with replacement costs typically ranging from $40 to $120 per linear foot. If your project also requires integrating a metal fireplace, budget for that additional expense before finalizing your material choice.

Chimney Replacement Cost by Size

Chimney replacement costs range from $40 to $250 per linear foot, with total expenses rising as chimney size increases. Larger chimneys demand more materials—such as brick or stone—and more labor hours, both of which drive up the final price. 

Here is a breakdown of average costs by chimney size in linear feet:

Chimney Replacement Cost Factors: What Affects the Price?

Many variables affect the total cost of replacing a chimney, from the condition of the mortar and crown to the complexity of the stack replacement. Understanding these factors before you start helps you build a realistic budget and avoid surprises once work begins.

Labor

Expect to spend $350 to $800 on structural engineer costs and $50 to $75 per hour for masonry work. Labor for chimney replacement requires both a structural engineer and a masonry expert, given the safety demands of the work. If the old chimney must be removed, a demolition crew will add approximately $50 per worker per hour to your total.

Permits

Chimney replacement—especially when it involves removing an existing structure—often requires a permit, which costs about $20 to $150 depending on your location. Check with your local building department before work begins to confirm which permits apply to your project.

Fireplace Replacement

Your fireplace replacement options and the type of fireplace significantly affect your total chimney project cost, with costs ranging from $700 to $7,200. Partial replacements that preserve the hearth cost less than full dismantling. Factors such as adding a new fireplace, dealing with asbestos, and your choice of materials and design all push costs in different directions. 

Here are the costs for fireplace replacements, including the price of removing the old fireplace:

Chimney Height

Chimney height is a direct cost driver because taller chimneys require more materials and more labor hours to complete. The EPA states that a solid chimney should extend at least 15 feet, but your actual height depends on ceiling height, number of floors, and chimney placement within the home. A two-story home will require a significantly taller—and more expensive—chimney than a single-story home.

Why You Should Hire a Chimney Installation Pro

Hiring a local chimney repair specialist ensures your chimney project is safe. Improperly constructed chimneys can pose serious fire hazards, allow smoke or carbon monoxide to enter your home, and compromise the structural integrity of your roof. Even if you've handled risky DIY projects before, this is one job you don't want to take a chance on.

Here's why it's ideal to hire a chimney installation pro

Chimney installation is complex and dangerous work, so here's why you should hire a pro:

• Pros have the necessary tools, safety equipment, and expertise to install chimneys safely and efficiently.

• They're familiar with building codes, clearance requirements, fire safety regulations, and proper ventilation standards.

• They can help you choose the right chimney type, flue liner, and materials for your home's heating system.

• A pro knows how to prevent leaks and future damage, and they can lower the risk of smoke backup or carbon monoxide exposure.

• DIY chimney installation can be dangerous and may lead to serious safety and structural issues.

• A pro chimney installer offers warranties and carries insurance.

• Pros can identify and address related issues—such as deteriorating masonry or flashing problems—before they worsen.

• A professionally installed chimney is more likely to pass inspections, improve energy efficiency, and increase your home's value.

Does Replacing a Chimney Add Value to Your Home?

Replacing a chimney can add value to your home—especially if your existing chimney is in poor condition or is nonoperational. Exactly how much value you'll see depends on the type of replacement and how much replacing it improves the functionality of the chimney. Overall, expect to see a return on investment (ROI) of around 50% to 80% . If you update your fireplace alongside your chimney, you could see an ROI of up to 91%.

One study of home sales conducted by the National Association of Realtors found that adding a fireplace to your home increases the selling price by approximately 12%. However, check with a local property appraiser to determine how replacing a chimney will increase your home's value in your market area.

Chimney Replacement vs. Repair

Whether or not you should repair or replace a damaged chimney depends on your budget and the chimney's condition. Minor repairs, like chimney parging, may be more affordable than a complete replacement. However, when there is significant damage, replacing an old chimney is cheaper, safer, and easier. A chimney that is not structurally sound may collapse or catch fire.

You'll also want to consider the lifespan of different parts of a chimney. Mortar on a chimney lasts 25 to 30 years, while chimney crowns may survive up to 75 years. To ensure your chimney is safe, have your chimney inspected and maintained by a chimney sweep once a year, which will cost around $250 .

Signs your chimney may be at the end of its life include:

• Leaning

• Leaking

• Crumbling or deteriorating bricks

• Cracking in the chimney crown

• Chipping or cracking in the mortar

• Discoloring in the wall or ceiling around the chimney

• Rust appearing in the firebox or damper

• Choose a budget-friendly chimney material, like metal or brick, instead of stone.

• If possible, choose a shorter chimney height.
