We all love to gather around a cozy fireplace on a cold winter day! But, remember that behind every sizzling fireplace, there’s a chimney that does the hard work by drawing out all the smoke and hot flue gases. If you don’t look after your chimney properly, a small issue may turn into a huge problem very soon — forcing you to spend a lot on chimney repair costs.  

Since a chimney comprises several vital parts including a firebox, damper, flue, liner, crown, and cap, you need to ensure that each of these works well. Failing could lead to water infiltration, embers escaping into the walls, blockage of the flue or the masonry, and crown cracking. 

A faulty chimney will not only harm your fireplace, but it will also compromise your home safety. Therefore, it’s important to keep your chimney in good condition. Apart from saving you from high chimney repair costs, it might even save your life!

If you’re looking to repair your chimney — maybe because it’s suffering from age, damage, or other structural issues — you’re in luck! We have Chuck Roydhouse, a retired professional firefighter, owner of Clean Sweep of Anne Arundel County, and President of The Chimney Safety Institute of America (CSIA) answering all your chimney-related questions. 

With a degree in Fire Science from Shepherd University and 25 years of experience as a career firefighter, Roydhouse is an expert on maintenance as well as performance of chimney and venting systems. 

Fortunately for us, he has provided a complete guide on chimneys, including chimney repair costs and some expert maintenance tips.    

What is the average cost for chimney repair?

The average cost of chimney repair is between $300 and $4000. Of course, the total cost to repair a chimney depends on the extent of the damage, the materials, and its location.

Roydhouse says that “Because of the different materials used, the maintenance and cost factor for chimney repair is going to vary greatly. Chimney repairs, depending on the materials and what you’re doing to the system, can be anywhere from hundreds of dollars to thousands and tens of thousands of dollars.”

Therefore, it’s better to get a chimney specialist to inspect the condition of your chimney and get an estimate before beginning the home improvement.

How often should you get your chimney inspected?

The rule of thumb regarding a chimney inspection is that you should get your chimney thoroughly cleaned and checked at least once a year. Having said that, you need to be always on the lookout for any potential problems. Timely preventive measures and chimney sweeping will help you avoid costly repairs and prolong your chimney’s lifespan.

A chimney pro will look at your chimney’s efficiency, system maintenance, any buildup in the smoke chamber, and overall consistency, to determine if the chimney is suitable for use. Scheduling an annual inspection is the best way to know if it’s time to make repairs to your system. A well-maintained chimney can last a lifetime!

What are the factors that determine the total chimney repair cost?

Roydhouse believes that “If you let time go on without doing preventative maintenance, obviously the cost factor greatly increases. Usually, the repairs that are most expensive are due to neglect, and if they would have been caught 5 years earlier, instead of spending maybe $10k-12k on repairs, the homeowner could have made a $900 repair and had no problems for maybe 10 years.”

Clearly, upkeep or tiny repair is much less expensive than it is to let things get out of hand. The quality of repairing materials, type of chimney, and complexity of the work also affect the total cost of your chimney repair.

Here are some types of chimney repairs and their costs to give you an estimate. 

What are the types of chimney repair work and their costs?

repairing a chimney

Leaking chimney repair cost

Fixing a leaking chimney costs about $150 to $350. A chimney can start leaking if rainwater gets in through the small cracks, usually at the roofline. This is generally due to damaged flashing and sealers.

Chimney sealing with mortar will cost you $180 to $350 while chimney flashing replacement will cost $200 to $350. Here, metal is installed as added protection against water infiltration — exactly where the chimney and roof meet. Just repairing the flashing will be cheaper — from $20 to $120.

Chimney repair cost based on chimney material

Your chimney repair cost depends on the type of chimney you have. For instance, repairing brick chimneys can cost anywhere between $175 and $4,000. A total chimney replacement or removal project will cost you about $10,000. The cost to repair a stucco chimney is between $570 and $4,200

Chimney crown repair/replacement cost

A chimney crown repair costs $150 to $300. It’s the slab of concrete at the top of a chimney that keeps the rain from coming down the flue, into your home. Moreover, it protects the brick and mortar of your chimney while keeping the pests out. Most importantly, it prevents the sparks from the chimney from landing on your roof.

A chimney crown replacement will cost you anywhere between $220 and $2,000

Chimney chase cover/cap replacement cost

A new chimney cover, sometimes known as a chimney cap, installation costs between $150 to $200. This cover is located at the top of your chimney and protects your flue.

Chimney flue repair cost

You can expect to pay about $200 for repairing a single flue tile — if it’s easily accessible, that is. Or, $65 to $100 per square foot. Do remember that repairing a cracked flue liner is just a temporary solution. It will need replacing eventually. Relining the chimney flue costs between $2,500 and $5,000. The total chimney flue liner installation could go as high as $7,000.

Tilted chimney repair

If you have a leaning chimney stack, it indicates that there’s an issue with the chimney’s foundation. A contractor will check if the horizontal mortar joints are level or not, and carry the repair accordingly. The repair work typically costs $3,000

Chimney wood rot repair cost

A homeowner can expect to pay a few hundred dollars or several thousand — depending on how extensive the wood rot is. A minor damage could cost $100 to $300 while a major renovation could cost $2,500 to $4,000. If the wood rot is beyond repair, you will have to replace or rebuild the chimney. 

How do I know that my chimney requires repair?

As mentioned, a yearly inspection of your chimney system can tell a lot about its condition. It’s especially critical if your home has witnessed a chimney fire, a lightning strike, or storm damage. Of course, some damage is obvious while others are not. That’s why it’s important to have your chimney inspected by a licensed chimney professional. 

In Roydhouse’s words, “ The #1 thing you want to look out for that will let you know your chimney requires repair is water damage — that’s the biggest threat to a masonry chimney because a brick chimney can absorb up to a cup and a half of water per brick. The weight of the water pushes the salts and minerals out of the faces of the brick, and you can see white stains on it. You’ll also likely see vegetation growth, and the actual mortar and brickwork will start to deteriorate and disintegrate.” 

He further explains that “If the water damage occurs in a chimney venting a furnace system that’s either oil or gas, then you’re dealing with carbon monoxide going through those openings or gaps or overheating in those areas.”

How much time does a chimney repair take?

Roydhouse states that “Depending on the severity of the repair being made, repair time can range anywhere from 30 minutes to 5-6 days. If you have something simple like maybe your flashing is starting to crack or pull away, there are repair methods to actually repair that and cover it up, and that’s something that, depending on the size of the flashing and what it takes to get to the flashing, could be done on-site during the inspection visit in 30 mins to 2 hours. 

If it’s a fairly normal roof and you can walk right over to the chimney and work off of the roof without setting up any kind of special ladder, plus you have the right temperatures outside and it’s not raining, these repairs can be made on-site in an hour or less on average.” 

Will homeowners insurance cover chimney repair?

According to Roydhouse, “It’s going to vary slightly by each individual’s homeowner policy, but typically, in my 30+ years of experience, the only thing that’s going to be covered by homeowners insurance is what’s listed in what’s called your peril part of your policy.

That would cover any damage that was created by a chimney fire event or a sudden occurrence (i.e. a lightning strike or a large tree that fell on your house and damaged your chimney or the chimney area). 

As far as normal wear and tear maintenance goes, like weathering and water damage due to neglect, they would not typically cover that. For example, if you didn’t properly waterproof your chimney and freeze/thaw caused the bricks to break down and faces to pop off (which is called spalling), they would not cover that as water damage, because that’s something you neglected. 

The same thing goes with chase covers. If you let it rust through and you have mold issues, that’s typically not covered unless you have a specific area on your policy that calls out for mold or some specific damage.”

Key takeaways

Always remember that your fireplace is only as good as its chimney. Since a chimney is an important structure of your home, you must take care of its exteriors and interiors. Make it a part of your routine home improvement.

The moment you realize that there’s something wrong with your chimney, you must get it fixed at the earliest. It will save you big money on your chimney repair costs.
