Changing Temperatures Can Seriously Damage Your Chimney

If any part of your home can withstand the notoriously harsh New York winters, it would be the chimney. Made of tough brick or stone, it has most likely seen decades or even centuries of unforgiving temperatures. While the chimney is particular strong and durable, it does have weaknesses and that includes dramatic changes in weather.

Chimney damage due to temperature changes starts with the presence of moisture in the structure. Aside from stone, all materials used to create a masonry chimney are porous and sensitive to contact with water. Even stone chimneys need mortar to bond the stones together, so they do not escape the dangers of water. When water hits materials like mortar or brick, the porous materials absorb the water like a sponge. While this does not have immediate repercussions, it will eventually cause damage.

During the bitterly cold winters on Long Island, every outside structure is subject to the freeze and thaw cycle. This includes your chimney. Now that the porous materials on the chimney contain water, the freeze and thaw cycle can damage the structure. The water inside the brick or mortar expands and contracts in freezing cold temperatures and this continuous movement weakens the brick and mortar.

Signs of damage due to changing temperature include cracks in the mortar, loose bricks or stones, missing bricks or stones or a listing structure. Without the proper attention and maintenance, a water and temperature damaged masonry chimney could collapse, which means serious costs.

You can protect your chimney from this type of deterioration in a couple different ways. One way to do this is to have a chimney service apply water repellent to the outside of the chimney. Using a water repellent instead of a sealant is crucial, because the repellent allows water vapor trapped in the masonry to escape, while it discourages water entry. A sealant will keep any moisture trapped and the damage will happen anyway.

Another way to protect your chimney is to have a chimney cap installed. A chimney cap is a small, simple contraption that covers the top of your chimney. Usually made of copper or stainless steel, chimney caps prevent water from freely entering the inside of the chimney. This can help prevent water damage to your masonry and water damage to other areas such as the flue, damper, and the inside of your home. In addition to keeping water out of the chimney, chimney caps also prevent animals from nesting in the flue and keeps live embers from escaping to create a fire hazard.

Both the application of a water repellent and the installation of a chimney cap should be performed by a licensed professional. Chimney caps sold by big box hardware stores are generally low quality and a chimney service can provide you with a properly fitting, high quality chimney cap that will last years longer. Also, both services pose serious danger to your safety, so consider leaving them to the experts.

HeatShield Ceramic Flue Sealant Can Save Your Fireplace and Home

A fireplace acts as a beautiful, sophisticated focal point in any home. It faithfully serves you every chilly New York winter, providing you with a source of heat and adding that special ambiance for holidays or get-togethers. In return, you lovingly address all of your fireplace’s maintenance needs on a regular basis by having professional chimney sweeps and inspections performed. Although regular maintenance can prevent many problems, it cannot always prevent everything. Specifically, if your inspector finds a hole or crack in the chimney lining or flue, this needs to be taken care of right away because it poses a serious safety hazard.

How is a Damaged Flue Dangerous?

Hearing from your inspector that your flue has suffered damage is not something any homeowner wants to hear. Oftentimes, people may brush the issue off as minor and forgo repairing the damage. Unfortunately, ignoring your damaged flue can have disastrous consequences.

According to the Chimney Safety Institute of America, when an unlined chimney is used to vent a fire, the adjacent structural woodwork can catch fire within 3 ½ hours. When gases from the fire escape the flue through a hole or crack, or if no flue is present to begin with, the hot mixture of smoke, toxins and particularly embers will seep toward your house’s structure. After a certain amount of exposure to the emissions of the fire, the combustible materials in your home (wood, drywall, plaster) will catch on fire.

In addition, the gases that escape from your flue deteriorate the mortar of your chimney. This also allows gases to travel closer to your home and even enter your home. Dangerous smoke, containing carbon monoxide and the known carcinogen creosote, is not something that should be in your home. Also, as the mortar deteriorates so does the structural integrity of your masonry chimney. After extended exposure to smoke, the entire chimney structure could potentially collapse – dangerous and costly.

How Should I Fix My Flue?

Instead of replacing your entire chimney liner, which can be expensive, you have another, more affordable option to repair it. Even if the damage is extensive, the product called HeatShield Ceramic Flue Sealant can repair anything – from plugging small holes to resealing an entire flue.

Chief Chimney Services says that HeatShield has the durability of ceramic and cement, and the product comes with a 20 year warranty when it is installed by a certified technician. A blade customized to your chimney applies and smoothes the material to any damaged areas of your flue. The HeatShield company also requires a video inspection before and after the application to ensure the highest quality work.

Who Can Apply HeatShield Ceramic Flue Sealant?

Only certified technicians can apply HeatShield Ceramic Flue Sealant, because they are trained to properly assess the damage, apply the product and guarantee a long lasting seal. If you live in Suffolk County, New York or the surrounding area, call Chief Chimney Services for a professional consultation from HeatShield-certified technicians.

The Rundown on Chimney Mold

Molds can pose serious health risks to you and your family. Don’t allow them to flourish in your chimney. Make sure water and moisture stay out!

Mold is something you never want in your home, and most people think of the basement as the most common area for mold growth. However, if you have a leaky chimney with water penetrating your chimney walls, your chimney can be a prime spot for mold growth. Mold can spread quickly through your house, so if you have chimney mold, it should be removed as soon as possible to keep you and your family safe from the adverse health effects breathing in mold spores can cause. Chief Chimney Services would like to answer a few questions for you about chimney mold to inform you how to be on the lookout for a mold invasion of your fireplace and chimney.

What causes fireplace and chimney mold?

According to the website Mold Advisor, unused fireplaces are the most common places for chimney mold to develop. The dark, damp, and poorly vented unused fireplace creates the perfect environment for mold to grow. The warm summer months, when you are not using your fireplace, is the perfect time for this to occur. The most likely fireplaces and chimneys to develop mold growth have leaks somewhere in the chimney because water is needed to allow mold to grow. Chief Chimney Services can not only take care of removing chimney mold, but we can also repair leaky chimneys to keep water out which lowers the possibility of mold to even occur.

What are the signs of chimney mold?

If the mold has spread, you may see mold growing on the bricks of your outer fireplace or even on the walls or ceiling of the room that contains the fireplace. If you do spot mold growth on the outside of your fireplace or in the room, call Chief Chimney Services immediately to have us inspect the inside of your chimney for more mold. Most likely, the mold is unable to be seen because it is only growing on the walls of the inside of your chimney. However, you will probably notice the distinctive musty smell of mold coming from your fireplace. You and your family may also be suffering from respiratory problems due to breathing the mold. If you suspect chimney mold, again call us as soon as possible to inspect your chimney and fireplace and remove the mold.

What are the adverse health effects mold can have on me and my family?

In the beginning, mold can cause breathing problems similar to the common cold with sneezing, coughing, headache, runny nose, and a sore throat. However, prolonged breathing of mold spores can cause serious illnesses like asthma attacks, chronic sinusitis, allergic reactions, and pneumonia.

How do I remove chimney mold from my fireplace and chimney?

You are strongly advised to allow professionals like Chief Chimney Services to remove all of the chimney mold growth as it can be a hazardous job. However, if your doctor okays it, you can clean up any exterior mold from bricks by using an antifungal cleanser and a stiff brush. Be sure to wear a breathing mask when cleaning up mold.

If you have any other questions about chimney mold, contact Chief Chimney Services today. Our staff is happy to assist you quickly with this possibly dangerous problem.

Help, My Chimney Stinks!

A stinky chimney is an indicator of an even greater chimney problem that exists or can possibly exist in the future. To get to the bottom of it, let our experts at Chief Chimney help you out.

We all want the same things from our chimney systems. We want a chimney that vents properly and thoroughly. We want a firebox and flue that provides the protection from high heat that they were designed to provide. We want a system that keeps moisture from making its way into the interior of our chimney — and the interior of our home. And we want a chimney that doesn’t stink.

As CSIA-certified chimney professionals, Chief Chimney technicians are focused on helping our clients get all of that from their chimney systems — optimum performance, optimum levels of safety, minimum levels of moisture intrusion, and a pleasant absence of stink. If you’ve been frustrated by a stinky chimney, we can help.

Chimney Odors Are A Warning Sign

The thing about chimney odor that we often don’t think about as we’re turning up our noses: It’s helpful, in a sense. That’s because ultimately, chimney odor is an indication that there’s a bigger problem going on in your chimney or with the use of your heating appliance.

A Musty, Dank Odor

If the smell you’re noticing is dirty, musty and dank, that’s most likely related to moisture, and very possibly is coming from mold growth. If you have mold or moisture, odds are you have a chimney leak.

Chief Chimney technicians can inspect your system thoroughly to figure out what’s allowing moisture to get into your chimney — which can be anything from a cracked chimney crown to damaged flashing, or something as simple as a missing chimney cap. When we find the culprit or culprits, we can make repairs to get rid of your leak — and get rid of that smell!

A Singed, Smoky Odor

Even though you’re routinely lighting a fire in your fireplace or stove, you shouldn’t smell a smoky odor in your home —your chimney is meant to carry away the byproducts that contribute to a smoky odor. So if you smell (or see) a lot of smoke when you’re using your appliance or in between uses, that’s an indication of a problem either with your venting system, or your burning practices.

If there’s a problem with your chimney’s draft — the upward movement of air that carries out combustion byproducts and smoke — you’ll most likely get an indication of that through a smoky stink. If you haven’t had the chimney swept in more than a year, there’s a good chance your problem is excess creosote buildup. But the problem could also have to do with chimney blockages, wind-induced downdrafts or a variety of other issues. We can inspect your chimney system to find your issue and correct it.

Smoky odors can sometimes just be the result of less-than-optimum burning practices, though — even something as simple as neglecting to open your flue completely during your fires.

Burning anything other than seasoned or kiln-dried cordwood — like wood that isn’t properly dried, trash or Christmas trees — can also cause your fire to produce excess smoke and excess creosote. In the case of burning green or moist wood, it can contribute to the development of troubling Glazed Creosote, which is extremely combustible, has a particularly strong odor and is really difficult to remove. If your flue has glazed creosote, we can remove it, and bring your system back to proper (and less stinky) condition.

If you have questions about the best burning practices and chimney odor problems, we’re always happy to help our valued clients. Just give Chief Chimney Services a call!

6 Questions to Ask Your Chimney Sweep

If you are in the market for someone to handle your chimney maintenance needs, we want you to know that knowledge is power.  Here are some questions you can ask prospective chimney sweeps to ensure that you hire the right professionals for the job.

We at Chief Chimney Services can answer all of your questions and provide you with peace of mind.

Chimney Care Checklist for Spring

Your chimney should be a priority in your home maintenance checklist this Spring. Do this every year and you’ll have a longer lasting, efficient, and healthy chimney system.

We know how it goes: The weather starts to warm up, and your fireplace and chimney system heads out of your mind. It’s understandable to close your flue for the season and not want to think about your chimney until next fall. But making chimney care and maintenance part of your spring home checklist can make your life easier, and your chimney system perform better.

Here are a few spring chimney checklist suggestions we have at Chief Chimney Services, with a little bit of “why” behind them.

Schedule Your Chimney Sweeping Appointment In The Spring

Every chimney system is different, but one thing we can tell you for sure: If you’ve been using your wood-burning fireplace or stove all fall and winter, your flue has creosote built up on its walls. As you burn wood, heated byproducts rise up to vent through your chimney, and your cooler chimney walls turn some of those gases back into liquid. That liquid layers and layers, and there you have it: creosote.

Ideally, you should have creosote removed during a chimney sweeping appointment before you start using the system over the next heating season. But here’s one reason why we think it’s preferable and better to make that appointment this spring: Your home will smell better all summer. That creosote has a smoky, sooty odor, and the heat and humidity of the summer brings that odor out. If you’ve ever noticed an acrid smell in your home during the summer — even though you haven’t used your fireplace in months — creosote is the source. Having your chimney swept in the spring means nicer-smelling air in the summer.

Schedule Your Annual Chimney Inspection In The Spring Too

To properly maintain your chimney system, an annual chimney inspection is a must. And again, you’ll want to make sure it’s done before you start using your heating appliance when the weather cools again. But there are definite benefits to getting this work done early, in the spring.

First, you’ll catch Chief Chimney Services before our busiest season, which means you’ll have broader options for appointments. But also, when that first cool night comes around, you won’t have anything to think about — your system will already be ready for warm, cozy fires.

Prepare Your System For Spring Rains

A lot of the chimney repairs we do at Chief Chimney are to the parts of your system that are designed to keep moisture out. Water is your chimney’s worst enemy, and we’ll do anything and everything we can to keep it from making its way in.

Moisture and your chimney’s relationship with it is something well worth thinking about in the spring, before the heavy rainy season rolls in. If a small problem in your chimney crown or chimney flashing has developed over the winter, spring rains can lead to chimney leaks and water damage to the interior of your home. Chief Chimney Services technicians can find those issues during a spring chimney inspection, and make any repairs necessary to arm the system against moisture intrusion again.

We can also recommend and apply a specially formulated waterproofing sealant for your masonry chimney that will significantly boost its ability to protect against water. Waterproofing keeps moisture from permeating the masonry itself, which not only keeps water out in the short term, but can protect your bricks and mortar joints in the long term.

If you have any questions about chimney maintenance and care — including making that part of your spring routine — Chief Chimney Services is always here to help. Give us a call!

Three Common Chimney Inspection Stories

Fred and his family have lived in the same home since it was built over 9 years ago. Every year during the cooler months, they enjoy gathering around the big pot belly stove that sits in the corner of their living room, providing warmth and comfort as it always has. Fred marks the beginning of the season with his annual order of one cord of firewood, which usually gets him through, more or less. The wood is always properly seasoned and stored, and on the day it arrives, his wife will make a big pot of chili as she always does, and the kids will help him unload the wood and stack it on the rack. Afterwards, they will all gather around in the living room and enjoy the first golden fire of the season.

The Firewood is Ready – Suffolk NY – Chief Chimney Services

But Fred has never taken this important appliance for granted. Every year, he calls out his local chimney service company to perform a Level 1 inspection, and if necessary, a cleaning. The purpose of the inspection is to make sure that the stove and venting are in good serviceable condition, and there are no leaks, combustible deposits or obstructions. Since Fred uses the stove every year, and nothing has changed in 9 years, a Level 1 inspection is all that is needed to keep a well-maintained system working like it always has.

But late last spring there was an earthquake. Nothing too big, but everyone in the area felt it, and most of his neighbors had gathered out in the street in the middle of the night, in slippers and robes, comparing notes and calming down the kids and dogs before returning to bed. Later that same year, several friends down the street had reported some cracks they had never noticed before in the masonry of their homes. It was generally agreed that these new issues were probably related to the earthquake.

So this year, Fred needed a Level 2 inspection of his chimney, just to be safe. In a Level 2 inspection, a certified and trained chimney specialist will use a video camera to inspect the inside liner of the chimney flue, looking for cracks or gaps or other damage that would prevent safe use of a fireplace or stove. The professional will also access hidden areas that intersect with the chimney system, such as basements, crawl spaces or attics, to make sure that proper clearance to combustibles is observed.

During his inspection, the technician observed no damage to the brick, mortar or liner of the chimney system. But when he was in the attic, he did find that a large, high-placed box had spilled over, probably during the earthquake, and its clothing contents had landed against the outer bricks of the chimney, causing a fire hazard. Fred was more than happy to pay for this discovery, because it meant that his family was spared any unnecessary risk that year.

Also this year, Fred has an opportunity to purchase his first rental property. It’s a real country fixer-upper, but given the price and the way the market for such properties has been going, it’s almost too good a deal to pass up.

Given the age and condition of the house, Fred made sure that his offer was contingent upon a Level 3 inspection of the two chimneys, among other things. A Level 3 inspection means that it is necessary to remove certain components of the building or chimney in order to gain the access needed to properly inspect a chimney. In this case, it meant that a small section of plaster above the location of the old stove in the kitchen needed to be removed so that the inspector could determine if repairs would be necessary before a new wood-burning kitchen stove was installed. It also was necessary to remove a chimney crown on the second chimney, which was already in bad repair. These inspections revealed what they needed to reveal, and Fred made adjustments to his offer. If all goes well, his offer will be accepted, and he will start the renovations with his oldest son before the weather gets too chilly.

Chimney inspections are required in order to ensure proper and safe operation of any vented fire appliance. These inspections must be carried out by a certified chimney professional (A CSIA Certified Chimney Sweep). If you are unsure about which inspection level is appropriate in your circumstance, please call us. We would be happy to talk about what we do and how we can help you.

Is There Too Much Creosote In Your Chimney?

People who have chimneys in their home no doubt know about the obvious dangers that they come along with, including blazing chimney fires. However, creosote poses a serious risk if it is left to accumulate in the chimney and many homeowners are unaware of it. Understanding this chemical compound and what it can do is essential to maintaining a home that is healthy and safe for the entire family, even those who do not come into direct contact with the fireplace or chimney.

Creosote is a combination of chemicals that is used to treat wood and coal. When these materials burn in the fireplace, they leave a layer of the creosote behind on the inside of the chimney. Over time, the creosote will accumulate and then the family may have to face a number of different risks if they do not properly take care of it.

Creosote buildup can cause Chimney fires – Suffolk NY – Chief Chimney Services

One of the biggest risk factors associated with creosote is that it is extremely flammable. It would take only a small spark from the fireplace to ignite the entire chimney. This can start a fire that will not only damage the structure of the chimney but that could potentially spread throughout the home. This is an especially significant risk in the event of negative air pressure, which sends material from the chimney into the home instead of out of the flue.

If creosote or smoke from burning creosote enters the air, everyone in the home will be at risk for health issues. Inhalation of creosote has been linked to a number of serious health problems, including respiratory illnesses as well as damage to various organs. These effects have been especially severe in the cases of children. Although some conditions can be treated, it is also possible that the effects of creosote could be fatal if left untreated over time.

In addition to doing internal damage, creosote can be dangerous for anyone who comes into physical contact with it. Just a bit of exposure can cause minor skin irritations and, in some people, severe rashes on the skin. The substance can also cause significant damage if it comes into contact with the eyes. Not only will it cause a painful irritation, but it has also been connected with a loss of sight.

Anyone who burns treated wood and coal in their fireplace should assume that they have at least some creosote inside of their chimney. There is no avoiding the residue when the treated material is burned. However, there are other signs that there is a significant accumulation of the material in the chimney. For example, when it burns, creosote will have a distinct smell that should come straight through the fireplace and into the home.

The best way to deal with accumulation of creosote is to have a cleaning by a professional chimney sweep at the end of each cold weather season. Since there are so many health dangers associated with it, the average, untrained person should not attempt to clean it up on their own. A chimney sweep has the proper tools and training to safely rid the chimney of excess creosote. An annual cleaning is the best way to keep the chimney safe and clear.

Creosote is a typical problem for anyone with a fireplace but it is a fairly easy issue to manage. Remember to have a chimney sweep come in each year to clear it out and to check for any damage to the chimney. Failure to take care of this could result in illness, physical injury, and devastating chimney fires. Let a professional bring peace of mind along with an efficient heating system.
