All You Need to Know about Glazed Creosote Removal

If you have a wood or oil-burning furnace or fireplace, you may have heard about glazed creosote. Information online, in the hardware store, and from well-meaning friends or loved ones may be confusing.

Chief Chimney Services has all the information you need to keep your home or business safe from glazed creosote.

What is it?

Creosote is a highly flammable, tar-like substance created when fuel is burned at high temperatures. This powdery residue can remain on the walls of a smoke box or chimney and compound over time in several layers. A professional will sometimes call this buildup glazed creosote, or level three creosote. At this level of buildup the creosote bubbles and boils when high-temperature fires burn in the furnace, then cools into a solid, very flammable, mass.

This hardened buildup can become a hazard as it begins to obstruct the chimney, causing the heat, smoke, and gases to slow, and begin to heat the flammable substance.

CSIA-Certified Chimney Technicians

At Chief Chimney Services, we are qualified, licensed, and insured to clean and repair damage caused by glazed creosote. Our licensed chimney sweeps are the difference in chimney maintenance. Using the proper tools we can transform the glazed creosote into a more pliable substance to be easily removed.

What We Do

The Chimney Safety Institute of America (CSIA) recommends regular chimney cleaning and inspections, and urges consumers to not depend only on chemical cleaning products like those found in hardware stores. A licensed and experienced chimney sweep provides fast service, inspections, and offers expert advice.

The way our chimney sweeps remove the creosote will depend on the consistency of the buildup. If it is gummy or moist we may use a chemical designed to transform the creosote to a powdery substance. This allows our sweeps to brush it out. These chemicals are safe for your home or business, and our chimney sweeps are qualified and experienced in their use. If a chemical remover isn’t needed, we use tools and brushes to detach the creosote from the chimney walls. After the creosote is properly removed, the chimney returns to safe function.

What You Can Do

As a home or business owner you can regularly check your firebox and chimney for signs of creosote buildup. Burning a high-temperature fire, with plenty of oxygen to the flames, helps the fuel burn completely. Also, burning proper fuel can help prevent creosote buildup. Proper wood should be cut and set aside to dry. This process could take as little as six months, or up to two years for denser types of wood.

Creosote is caused primarily when wood isn’t completely burned. So using improperly seasoned wood raises the risk of buildup.

In addition to burning proper fuel, home and business owners should not skip an annual cleaning and inspection. A regular cleaning should remove creosote before it reaches level three buildup.

Dealing with Draft Problems in Your Chimney

Perhaps you were never able to use your fireplace, or you used to, but it started backing up smoke into the house. When the smoke and hot air fails to escape through the flue, your fireplace and chimney are said to be experiencing drafting problems. A wide variety of issues can lead to drafting problems, and oftentimes, they completely baffle and frustrate homeowners.

One easily resolved cause of smoke back up is a closed damper. The damper assembly acts as a door to allow smoke and hot air to escape through the flue when a fire is burning and to keep the furnace-heated air inside from escaping when the fireplace is not in use. If the damper stays closed during a fire, the smoke has nowhere to go except into the house.

Another common drafting problem is an obstructed flue. Animals like birds, raccoons, or squirrels seek out the warmth and safety of the chimney during cold, winter months. These animals and their nests will partially or completely block off the flow of smoke through the flue. A chimney service can install a chimney cap for an affordable price to prevent animals from nesting in the flue.

An obstructed flue can also be caused by the buildup of creosote, a tarlike compound created by burning wood. A health threat in and of itself, creosote also builds up inside the flue and may eventually seal it completely. To prevent this and the other dangers of creosote, have a mason sweep your chimney at least once every year.

Your chimney can also experience drafting problems when the firebox and flue do not fit together properly. The size of the flue compared to the size of the firebox should follow a 10:1 ratio, meaning that for every 10 square inches of firebox, there should be 1 square inch of flue opening. If the flue size cannot accommodate the volume of smoke produced by the fire, the smoke will back up into the house.

Additionally, the flue should be positioned deep inside the firebox, and the fire should be built as far back as possible. If the fire sits too close to the interior opening of the firebox, it will never have a chance to enter the flue before seeping into the house instead. This could become an issue if the firebox was installed improperly or if it was not manufactured according to fire safety codes. A mason can help you make the right choice in addressing this issue.

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.

Tell Me About Chimney Mold

Water in your chimney allows mold to thrive. This is not a good thing. Make sure to waterproof your chimney.

As chimney professionals, a lot of what Chief Chimney Services technicians will talk to homeowners about regularly focuses on preventing fire hazards, maintaining proper draft and keeping up with regular maintenance. It’s also important for us to talk about something that might seem a little less obvious with your chimney system: mold growth.

Mold can and will grow and spread just about anywhere it gets access to moisture and food (like the building materials that make up your home). So if moisture makes its way into your chimney — through damaged masonry or other damaged components — that dark, enclosed and moist space can make a perfect home for mold. Since our chimneys are largely dormant for months out of the year, and Long Island humidity contributes a healthy share of moisture just about year-round, we need to be particularly aware of chimney mold here.

Why Do I Need To Know About Chimney Mold?

Mold growth creates stains and smells, and those annoyances are reason enough to not want it in your home. But related health issues are more concerning. Airborne mold spores have been shown to contribute to a variety of health issues, including respiratory problems, skin and eye irritation and longer-term illnesses. Certain types of mold — so-called “black mold” — are toxic, and have been linked to severe issues from pulmonary illnesses to nerve damage and more. People who already struggle with asthma and other respiratory illnesses or have weakened immune systems have been found to be particularly susceptible to the effects of mold. So it’s important to know about mold growth, and to deal with it quickly if it’s found in your home.

How Do I Know If There’s Mold In My Chimney?

It’s possible that you’ll see the signs of mold on or around your chimney — like discoloration of the masonry or adjacent building materials, or flaky and crystallized white efflorescence, which isn’t mold, but does point to a moisture intrusion problem. More often, though, if mold is growing inside your chimney where it isn’t in plain sight, the first indication will be a musty odor. We all know the smell of mold — it’s what most of us think of as that dank and unpleasant old-basement smell. If you notice an odor, Chief Chimney Services can inspect the chimney to assess whether there’s a moisture issue and mold growth.

How Does Mold End Up In My Chimney?

Mold spores are everywhere, and if they get a dark space to thrive and moisture to feed on, they’ll grow. So mold growth in your chimney is a sure indication that there’s a moisture issue — and dealing with that moisture issue is the key to dealing with your mold.

What Can I Do To Get Rid Of Mold In My Chimney?

The most effective way to get rid of chimney mold: Call Chief Chimney Services. Since breathing mold spores can be dangerous, it’s generally not advised to clean mold yourself on a space that’s any larger than 10 square feet (about a 3 by 3 square). If there’s mold growth inside your chimney, it’ll require special tools to properly get to it, as well. But beyond that, cleaning mold without addressing the moisture intrusion or leak issues is a temporary fix — the mold will grow back again. We can inspect and clean your chimney, find any leaks or moisture intrusion issues (which can be anything from degraded masonry to a cracked chimney crown  or damaged flashing) and provide solutions and repairs.

If you have any questions or concerns about chimney mold, we’re always here to help. Just give Chief Chimney Services a call!

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!
