A chimney repair can include many different types of issues affecting all parts of your chimney. While some problems may be obvious to you, a pro can properly diagnose the problem and clue you in on the best solution. Below we’ve outlined a few common chimney scenarios with their estimated pricing.
Fixing your chimney crown costs $150 to $300. Chimney crowns (sometimes mistaken as chimney caps or covers) are the slab of concrete at the top of a chimney. They do more than just keep rain from coming down the flue and into your home. This part protects the brick and mortar of the chimney and keeps pests out as well.
Not only does the crown keep things out, but it also keeps things in, preventing sparks from flying out of your chimney and landing on your roof.
You’ll pay anywhere between $220 and $2,000 to replace the chimney crown. Cracks that form in the crown can be particularly costly if left unrepaired. Water can get into the cracks and cause significant damage to mortar, bricks, and even the wooden frame of your house. Eventually, these cracks will compromise the integrity of your chimney and fireplace, requiring a total replacement or removal. This can cost thousands of dollars. As such, it’s to your benefit to repair or replace the crown as soon as there’s a problem.
Expect to pay $150 to $200 with installation for a new chimney cover. The cover (sometimes called a cap) protects your flue and is at the very top of the chimney.
Repairing a single flue tile will likely cost no more than $200 if it’s easily accessible. Fixing cracked tiles in your flue costs anywhere from $65 to $100 per square foot. However, repairing a cracked flue liner is only a temporary solution. Eventually, it will need replacing.
Installing a chimney flue liner costs most homeowners $2,500, but could cost as much as $7,000. Relining your flue costs between $2,500 and $5,000.
Fixing a leaking chimney costs $150 to $350. Water can get in through cracks and cause damage in the form of mold and wood rot. These cracks are usually at the roofline when flashing and sealers fail and allow rainwater to seep inside. Here are some ways to repair a leaking chimney:
Chimney sealing ($180-$350): Cracks are sealed with mortar.
Chimney flashing ($200-$350): Metal is installed where the chimney and roof meet as added protection against water infiltration.
If it doesn’t need replacing, repairing flashing costs anywhere from $20 and $120.
Leaning chimneys typically cost $3,000 to fix. Oftentimes, a leaning or tilted chimney stack indicates an issue with the foundation. A contractor will find out if it’s a foundation issue by checking whether or not the chimney has level horizontal mortar joints.
While fixing small cracks may cost less than $500, deeper cracks or those that affect a large area could reach up to $1,500.
Repairing chimney flashing typically costs between $200 and $500, depending on the size of the chimney and the extend of damage. For larger chimneys made of stone or brick that require flank flashing and its more extensive installation process, you could pay up to $2,000 for a repair job.
The material your chimney is made of will affect your final repair cost.
Repairing brick chimneys costs $175 to $1,000 on average. More extensive damage could run upwards of $4,000 and a total chimney replacement is about $10,000.
|Repair||Cost to Fix|
|Cracked Bricks (less than 10 bricks)||$175 - $500|
|Cracked Bricks (more than 10 bricks)||$750 - $1,500|
|Crumbling Brick||$350+ (to replace 10 bricks)|
|Cracks in Masonry||$300 - $1,000|
Keep in mind, some contractors may charge more for projects above 10 feet. Brick chimney work might cost less if the location for repairs is closer to the ground.
The price to repair stucco is between $570 and $1,920, but more extensive projects can run as high as $4,200. Fixing a stucco chimney ranges from $1,000 to $4,000.
It will typically cost between $200 and $1,200 to repair a metal chimney. This material is highly durable but can dent during major storms. If you just need to replace the flashing on a metal chimney, this will typically cost around $300.
A prefabricated chimney will cost you about $200 to $1,200, as they are typically made of metal and share the same repair costs. This price range reflects a general range for minor issues to severe damage.
Expect to pay $175 to $3,000 to repair a chimney crack. Masonry joints expand and contract with temperature fluctuation. This can lead to cracks forming and allowing smoke, carbon monoxide, and sometimes even stray embers to get between your walls our out of the chimney and onto your roof.
Cracks will most often form at corners before they form anywhere else. However, cracks in the middle of the back of a fireplace aren’t uncommon. If found early enough, simple brick mortar repair can resolve the issue. If left untreated, they can lead to structural damage, increased risk of fire, and can cost upwards of around $3,000 to repair.
Depending on how extensive the wood rot is, you could pay a few hundred dollars or several thousand. If the damage is confined to one spot that’s easy to access, you might only pay $100 to $300. A bigger area of wood rot might cost $2,500 to $4,000 to fix. If wood rot is too far gone, expect to replace your chimney for $10,000.
Sealing your chimney with HeatShield is typically between $2,500 and $3,500. Price estimates vary based on location and how extensive the project is.
Chimney parging coats the smoke chamber with mortar and costs $1,000 to $2,000. Parging smooths over the smoke chamber so that any residue that lies in uneven crevices doesn’t leak out or combust.
Chimney spalling repairs cost $1,000 to $3,000 on average. Broken or missing bricks an example of chimney spalling, and if left untreated, it could lead to significant damage that can cost $3,000 or more. Since bricks rely on mortar and surrounding bricks to stay in place, spalling makes it easy for other bricks to deteriorate. Since bricks rely on mortar and surrounding bricks to stay in place, spalling makes it easy for other bricks to deteriorate.
One important note: If your chimney needs any type of repair, you should hold off on using your fireplace until it’s fixed. Using your fireplace could worsen the damage and put your safety at risk.
Repointing brick costs $700 to $2,200. The mortar between bricks wears down over time; repointing repairs the mortar to prevent your chimney from collapsing.
Similar to repointing, tuckpointing a chimney ranges from $700 to $2,200. While repointing removes and repairs the mortar, tuckpointing is the process of filling in mortar and making it aesthetically appealing. This involves blending in the mortar to match with the bricks. While repointing and tuckpointing are technically different, they’re often lumped into the same service. Talk to a fireplace contractor near you for an estimate on repointing or tuckpointing your chimney.
Grout and mortar cost about $2 to $3 per square foot, plus at least $40 to $50 per hour in labor. The exact price depends on the size of your chimney. Even if the mortar of your chimney is crumbling, you might not need to buy new bricks. Re-mortaring could save you money by reusing bricks.
When it comes to cleaning and maintaining your chimney, annual visits from a chimney sweep are key.
You can expect to pay around $250 for the cost of a chimney sweep, with simple cleanings ranging from $80 to $200. Aim to schedule cleanings at least annually for safety and to cut costs later. You could pay around $800 to clean a neglected chimney.
If you’re keeping up with your cleanings and there are no major issues, you may only need a level one inspection, which is typically included in the cost of cleaning. A level two inspection, which you’ll need before some repairs and updates, will typically run you $100 to $500.
For major structural damage, you’ll need a level three chimney inspection, which runs from $1,000 to $5,000.
Homeowners' insurance will only cover chimney repair if it’s the result of an unexpected event. If your chimney experiences damage from a tornado, lightning strike, or another weather-related incident, insurance should cover it. With that in mind, it’s unlikely that damage from high winds will be covered. Insurance also won’t cover routine inspections or general repairs.
This decision will depend on the extent of the damage and your budget. If you’re only dealing with a minor issue, chimney repair is usually your best bet. However, if there is extensive damage or you want a new look, you may want to take on the cost of removing a chimney.
Cracked chimneys pose a threat to your house and your safety. Moisture seeps into the cracks and causes further cracking. A cracked chimney that’s not repaired quickly can collapse and damage part of your house or increase the chances of fire.
This problem could have a few roots, including issues with your draft fan and your damper. The best way to get to the bottom of it is to call in a chimney repair pro.
Restoring a chimney costs anywhere from $300 to $4,000. The price varies based on how complex a project is.
