What Are the Best Chimney Crown Repair Products?

Chances are, most homeowners might not even notice the crown of their chimney. 

Unless they get on their roof to clean the gutters, put up Christmas lights or perform an annual roof inspection (which isn’t likely) the health of a homeowner’s chimney usually goes unnoticed – which isn’t necessarily a bad thing. 

However, there are instances where it is very obvious that a chimney is in need of some TLC, and that is when homeowners start calling. 

What they usually see – a damaged chimney crown that is in need of some repair. 

So when this happens, contractors have to decide on what is the best chimney crown repair product to use. Well, this article should help.

Chimney Crown Repair 101. 

The crown of a chimney acts like an umbrella or roof for the chimney structure and system. Not to be confused with a chimney cap, the chimney crown is the cement “Top” of a chimney. 

The role of the chimney crown is to prevent moisture from entering a chimney. A crown is comprised of cement or concrete and when properly designed, installed, and maintained chimney crown facilitates water run-off from the top of the chimney down the sides, thus preventing standing water and potential damage from freeze/thaw cycles.

However, there are times when the crown of a chimney needs repair.

Common repair causes include:

  • Cracks in the chimney crown
  • Missing pieces or chunks of concrete
  • Structural integrity is compromised

Some repairs can be simple, such as sealing a crack and resealing the entire crown. Others can be more extensive and require a multitude of things to correct the issue. 

In this case, it’s important to choose and use products that can get the job done and prevent any further issues!

Are you a homeowner and want to know how much a chimney crown repair costs?

Some repairs are simple, such as fixing a crack or resealing the surface, while others can be complicated and laborsome. It is always best practice to make sure you use high-quality material and get a few quotes when looking into repairing your chimney’s crown!

Final Word on Chimney Crown Repairs & Products

The old adage, “You get what you pay for,” is certainly true when it comes to repairing the crown of a chimney with the right products. Similar to how gutters that are installed incorrectly don’t perform – the same can be said for your chimney crown!

An inexperienced contractor who just uses a common mortar mix to fix a damaged chimney crown is simply putting a bandaid on the problem, and it is only a matter of time before the same issues occur again. 

Weather such as rain, snow, freeze and thaw cycles make the crown of a chimney vital to the overall health of a masonry chimney. However, a small crack can lead to an even bigger issue because of the aforementioned weather. 

When moisture enters the chamber of a chimney, the issues go far beyond just a chimney crown crack. 

In order to prevent any chimney issues, it’s best to check the crown health at least every other year and keep an eye out for cracks. Preventative measures are always the best bet – just like getting a check-up at the doctors. 


Contactors: CrownGuard HP can be used as a preventative measure for chimney crowns and installed on brand new or existing chimneys. For more information, use the tap the button below:

Masonry Chimney Repair 101 (Everything You Need to Know)

I will never forget the first (and hopefully the only) home fire I saw. 

It was late one July 4th when evidently a neighbor a few blocks away had improperly stored his discharged fireworks. Instead of leaving them in a bucket of water, he had placed them in his garbage can. 

As if placing his fireworks in a sealed plastic garbage container wasn’t bad enough, he then proceeded to leave the garbage can in his home’s garage. 

By the time the rescue squad arrived, it was too late – the house had been ravished on all three floors by a sweeping hot fire. Luckily no one was injured in the blaze. 

In doing research, the most common cause of home fires is smoking, followed by cooking and electrical malfunction. While many of the common home fire causes are controllable, some like electrical malfunctions or faulty masonry chimneys aren’t as easily diagnosable. 

However, when diagnosed a masonry chimney is nothing to wait around for, which is why we wrote everything you need to know about masonry chimney repairs in this article. 

But first, you might be asking: 

What exactly is a masonry chimney and why would you need to have a chimney repaired anyways?

Masonry Chimney Repairs:

If you’re wondering what just exactly is a masonry chimney, don’t worry we got you covered. Chances are if you have a chimney at your home – it’s most likely a masonry chimney (unless it happens to be wrapped in siding). 

A masonry chimney can be constructed using a variety of masonry (think stone) and metal materials including: 

  • Brick, 
  • Mortar, 
  • Concrete, 
  • Concrete block such as cinder-block
  • Stone, 
  • Flue tile, and 
  • Steel or even cast iron.

There is a high probability that you have seen a masonry chimney just about every day of your life. While masonry chimneys might not be “The Standard” on all new construction homes these days, most home buyers still prefer the satisfaction of a beautiful brick or stone chimney. 

That being said, while masonry chimneys that are well built and properly constructed can last for a very long time (think of the Roman Arches that still exist to this day), that doesn’t mean all masonry chimneys are alike. 

Some masonry materials can be susceptible to weather and rain, especially if improperly installed. Not only can your damaged masonry chimney look bad, it can also be extremely hazardous!

Some chimneys might have issues, which is why it’s good to know when and if a masonry chimney needs to be repaired!

Did you know: 

There are some 374,000 house fires in the United States annually costing a staggering $8 billion dollars according to this article from 38 Companies Disasters Services. 

What are the most common masonry chimney repairs?

A problematic chimney can stem from a multitude of causes and there are plenty of possible problems to go around. However, the most commonly seen masonry chimney repairs typically stem from: 

  1. Cracks
  2. Chimney Liner Issues
  3. Chimney Crown Failure & Cracks
  4. Water Issues
  5. Faulty Chimney Design

Let’s take a quick look at each! 

1. Chimney Cracks

A crack in a chimney can be very evident, like in the photo below: 

chimney crown cracks
Chimney Crown with cracks!

The purpose of your chimney is to properly vent the products of combustion (smoke) form your home. However, if the integrity of a chimney is compromised, say from a crack, this can be an issue.

If smoke and combustion materials are not vented away from your home they can build up in said cracks, thus causing fire hazards. 

Cracks are one of the most common masonry chimney issues! 

A commonplace where you might find cracks in your chimney is in the crown. The photo above is actually an example of a failed and cracked chimney crown, another common masonry chimney repair item! 

Did you know: 

The number one cause for a chimney fire is a failure to clean a chimney adequately or often enough! Be sure to routinely have your masonry chimney swept! 

2. Chimney Crown Issues

The very top of a chimney is referred to as the “Chimney Crown.” Think of a king with his crown, you would notice a few things if the king’s crown was:

  1. Cracked
  2. Lopsided or 
  3. Falling apart

If any of these are happening to a masonry chimney’s crown, it is vital to get it corrected immediately. 

For one, a Chimney crown can get worse, the longer you take to correct it. Learn about a Chimney Crown here! 

3. Chimney Liner Issues

Your Chimney liner is a vital component of a chimney system. 

Depending on the chimney, a chimney liner repair can vary from centering and proper insulation to a refinished liner that is smoother. A smooth chimney liner is vital for a properly functioning chimney. 

A proper chimney liner should provide:

  • Maximum protection for your chimney.
  • Maximum protection in the smoke chamber.
  • Increased performance of fireplace or appliance.
  • Be uitable for all fuels.
  • Significantly increases structural integrity.

It’s best to always have an expert check out chimney liner to make sure water Learn about Firesafe Industries Guardian Chimney Liner products here! 

4. Water Penetration & Weather

According to Brick Restoration Inc., 

When water mixes with the creosote it becomes acidic which, in turn, causes premature rusting of the damper and speeds up the deterioration of the brick and mortar in your chimney & fireplace.

In other words, water penetration and outside weather factors are not good for your masonry chimney!

Whether water enters from the crown or a crack in your chimney, or even around the chimney flashing, there are simple repairs. 

Waterproofing, water sealants, repaired flashing and products like FireGuard are all solutions to a chimney impacted by water/weather! Which leads to our last and final chimney repair issue – design! 

5. Faulty Chimney Design

An improperly designed chimney can cause anything from a funky looking chimney to some extreme issues, such as fire hazards.  

Take for instance, the smoke chamber of a fireplace that is improperly designed or constructed. 

Similar to how a car must be designed to perform while simultaneously providing safety, a fireplace is very similar. The smoke chamber, liner, crown, flu and all aspects of a chimney not only work together, but they also rely on one another! 

masonry chimney repair from design failure

Faulty Chimney Design

You may or may not be able to see the faults in a chimney design. However, if you suspect something is wrong because you see what looks like a: 

  • Lopsided chimney
  • Deteroiaring chimney
  • Cracked chimney, or
  • Black smoke

Then it doesn’t hurt to get a chimney expert’s opinion, just to be safe!

How much does the average chimney repair cost?

Last but not least – costs. 

How much does the repair for a masonry chimney cost is a very common question, the issue? The answer really depends. 

A simple inspection of a brick chimney might result in a $250 crack being corrected. However, chimney repair services can range from $250 to several thousand and up depending on the extent of what needs to be repaired. 

According to a 2019 Home Advisor article, a masonry chimney repair can cost $1,000-$3,000 from the crown to the roof or over $10,000 if the entire masonry chimney must be rebuilt. 

In situations like this, it’s always best to contact a certified contractor to see what is needed. 

Final take on Masonry Chimney Repairs:

While I have only seen one fire in my life, the sheer harsh truth is this: 

There are some 374,000 house fires in the United States annually costing a staggering $8 billion dollars according to this article from 38 Companies Disasters Services. 

So while in some cases it might not seem like a big deal to find a little brick in your yard from your masonry chimney, it doesn’t hurt to do your due diligence. As we part, here are some final words if you’re a homeowner with a chimney:

  1. Get your chimney cleaned this year! Simply Google “Chimney Sweep Near Me” and find a good deal! 
  2. Ask the chimney sweep expert if they noticed anything. If they don’t great! If they do;
  3. Contact a local chimney repair company and have them inspect your Chimney

The 9 Most Common Home Services

Want to know what the top home services are that most homeowners are looking for each year?

Whether it is the lawn needing a fresh cut, the gutters in need of a solid cleaning, or the annual chimney sweep before winter – homeowners have a lot on their plate when it comes to home maintenance.

The time, energy, and knowledge involved when it comes to maintaining a home can be burdensome for homeowners. However, if you’re in the service industry, what does that mean for you?

Well, it means an opportunity for your small business! Here is what we mean.

9 Most Common Home Services

Below you will find a list (Not in order) of some of the most common home services homeowners look for on an annual basis!

Whether you already do some of these or if you happen to be in the process of adding a service to your repertoire, this list is for you!

1. Plumbing Services

plumbing home service

Ready for the most common home service call?

If you hadn’t caught on already, plumbing is typically the most commonly used home service when it comes to homeowners needing some help!

Whether it is a leaky faucet or clogged garbage disposal when the water drips – homeowners call like crazy! The following are some of the most common homeowner plumbing problems:

  • Garbage disposal issues
  • Leaky faucet
  • Running toilet
  • Clogged drains
  • Frozen pipes
  • Leaky pipes

On another note, if you’re a plumber, be sure to let your clients know to never put these types of things down their garbage disposal!

2. Gutter Cleaning

Who knew that those leaves piling up each fall around houses would also pile up in a homeowner’s gutter?

Each year leaves and fall foliage is found just about anywhere – from the entryway of a home to the downspout of a gutter. And when the leaves start to fall, leaves and other debris make their way into gutters. Which is when drainage issues can arise!

Homeowners who understand the importance of clean gutters are always quick to grab a ladder or call a service provider for their gutters each fall!

3. Paint & Drywall Repairs

Nail pops, cracks, water damage, or the ugly yellow bathroom in a home – you name it – painting and drywall services are something homeowners constantly are in need of.

While some homeowners might try and attempt to patch and repair drywall on their own like this guy…

Typically, most quickly realize patching and mudding drywall is not as easy as the camera makes it seem like! The same can be said when a homeowner decides to paint their kitchen.

It’s only a matter of hours before they are wishing they called someone!

4. Cleaning

The last thing anyone wants to do on a Friday after a long work week is clean, which is why you see the growth of the home cleaning service companies around the nation.

With more and more families spending time at work, children’s activities, and so on – the busy schedules have led to more homeowners who are in need of cleaning.

Typically, most homeowners are looking for someone who can clean the interior of their home on a bi-weekly or monthly basis. However, many companies offer as-needed cleaning services too!

5. Landscaping

Just like cleaning or painting, it’s only a matter of time before filling up a Saturday with yard work becomes a bit tedious.

Numerous landscape companies scatter just about every major city area offering landsacpe services ranging from weekly mowing all the way to full landscape architecture projects.

As a home service industry provider – landscaping is a niche that always keeps growing… literally! Landsacpe companies provide a multitude of services including:

  1. Lawncare
  2. Shrub & tree trimming
  3. Mulching
  4. Hardscapes
  5. Ornamental landscaping

6. Chimney Sweeps

A typical chimney sweep will cost a homeowner somewhere in the neighborhood of $125 according to an Angie’s List article, but it’s worth the cost.

Chimney sweeps are vital to having a safe chimney before burning logs or even using a gas fireplace. As the NFPA puts it;

Unclean chimneys are a leading cause of structure fires, according to the National Fire Protection Association, which recommends an annual chimney inspection.

National Fire Protection Association

That being said, in addition to having a clean chimney that is safe for the winter, here is another reason a chimney sweep is vital:

A chimney expert can spot structural damage to a chimney that a typical homeowner may miss.

chimney home service

What might seem like an innocent crack to a chimney’s crown or a slight compromise within the liner of a chimney, can actually be a huge deal!

Similar to not wanting the gutters to get backed up which can lead to significant water damage to a home, a compromised chimney may be in need of repair or restoration in a hurry.

Chimneys are an item homeowners don’t want to wait around getting repaired or refinished, depending on the chimney’s need.

7. Siding Repairs

A single piece of siding is a pain to replace?

Why? Well, that is because siding is installed piece by piece in an interlocking fashion. This is typically why homeowners don’t expierence just one piece missing – they expierence quite a few!

Siding repairs are no easy feat for a homeowner and they typically need to be done by a professional siding installation company! Homeowners know the importance of their siding, which is why it is commonly called for item!

8. Cracked Concrete

Perhaps you have seen some cracked concrete in a driveway, on a sidewalk or worse… on the foundation of a home.

No matter what the reason is for the cracking concrete, there is only one thing that is certain – the crack will get bigger in most cases.

Depending on the location of the crack, cracked concrete can be caused by a variety of things and can need urgent repair or not, it all just depends. However, repairing concrete cracks is not something most homeowners are privy too, so they typically call on this one!

Note: If in the event the cracked concrete is within a chimney, Fireguard is one of the top bets for helping with the crack!

9. Roofing Repairs

Similar to one piece of missing siding turning into twenty, a missing shingle can lead to many missing shingles in just a few wind storms.

While most new roofs have factory and install warranties, depending on the type of shingle or the age of a roof, roof repairs are common service calls homeowners make.

It’s typically clear when a shingle or two goes missing by the exposed plywood. However, there are instances where homeowners won’t always see missing shingles.

If you’re an exterior home service provider – be sure to encourage homeowners to check their roofs after the winter and each fall with binoculars!

Final Words:

At the end of the day…

At the end of the day, home services are one of the most common small (And big) businesses found in the United States.

Just look around when driving and you will see pest control vans, trucks, painting companies – you name it – offering a wide variety of home services.

So if you’re in the home service industry or even the commercial construction industry, this article hopefully shed some light on the top called about home service requests!
