Creosote
Creosote build up like this is a major cause of fireplace odors.

Creosote, a buildup of  the byproducts of combustion, can cause odor in your chimney which can permeate through your entire home. It takes only one use of your fireplace for a small amount of creosote to build up in your flue system, and when conditions are right the smell of the creosote can enter your home. The conditions which I am talking about include any which cause a down draft to occur. If you have negative pressure in your home and your home’s windows and doors are too air tight to permit any air to enter, air can be drawn down the chimney to make up for the lost air, bringing with it the odor of creosote.

Having your chimney cleaned can significantly reduce odor issues in your home by physically removing creosote, however, not all creosote can be removed by chimney cleaning equipment. Stage three creosote which has been glazed on can have odors and cannot be removed by most chimney cleaning equipment, instead it must be chemically modified in order  to be removed. If your chimney professional tells you that your chimney has glazed creosote, he will often recommend using a creosote modifying chemical such as Anti-Creo-Soot or Cre-Away, which will change the chemical composition of the creosote such that it is

ACS Spray Creosote Modifier
Anti-Creo-Soot helps to modify existing creosote such that it is easier for a chimney professional to remove.

in a form which can be swept away easily.

Using these chemicals is essentially painless and involves very little work on your part. Anti-Creo-Soot is a spray which is non-toxic and environmentally safe. During low fire conditions, spray this product into the firebox. It will help to convert creosote and soot into a harmless ash which can be easily removed from the fireplace. Anti-Creo-Soot is available in 32 oz. spray bottles and 1 gallon refill containers. Cre-Away is a powdered creosote modifier as opposed to a liquid spray. This product is

Creosote Modifier
Cre-Away is a creosote modifier which neutralizes creosote, eliminating its odor, while making glazed creosote easier to remove.

specifically designed to help to removed glazed creosote from the inside of your flue system. This product has a long straw which the product comes out from when the bottle is squeezed so that it will penetrate up into the flue system. Cre-Away helps by neutralizing the existing creosote so that it is less acidic on your chimney’s flue tiles and also breaks down the glazed creosote so that it can be removed.

When creosote is easier to remove, it is easier to eliminate the odor that creosote causes. Similarly, neutralized creosote loses a lot of its odor when it is neutralized as opposed to its natural, non-neutralized state.

Throughout the lifetime of your home, there is a large possibility that you will need to perform some type of maintenance in order to keep its intricately designed and delicately balanced parts from leaking or becoming damaged. The chimney and fireplace area, including surrounding drywall indoors, are prone to damage from water.

Rusty Chimney Flashing
Chimney flashing that is this damaged is better off being replaced than repaired.

If you are experiencing water marks on your ceiling or on the walls near the chimney, it is worth your while to take a look at the integrity of your flashing. If your flashing is rusted out or is pulling away from the home, replacing the entire flashing system is the best repair, but using a flashing repair system is another option especially if there is no visible damage to flashing. If you suspect that the flashing is simply no longer water tight, repairing it may be more appropriate than replacing it.

Other leaks which can damage the inside of your home due to damage on the outside include brick and mortar problems. Nothing is more unsightly when having the entire family over for the holidays than big water marks on the walls or ceiling near the fireplace where you keep your family photos and the holiday wreath. Cracks in the brick on your chimney are an obvious point of entry for water, and when water problems happen repairing cracks in brick is a step that should be taken even before the flashing is considered. Applying a flexible silicon sealant to the cracks is a must, and after this dries it is prudent

Breathable Water Repellent
ChimneySaver Water Repellent does not trap vapor in and instead allows the brick to breathe while still protecting it.

to cover the crack and the surrounding area with water repellent.

Even when no visible cracks can be seen and the flashing is intact, water is still able to get into some bricks. To prevent water from seeping into the pores of the brick and allowing the water to enter into your home, applying water repellent to the entire area near where the water damage is occurring  is one way to go. Be sure that the water repellent that you select is breathable and will not trap existing vapors inside the brick. If you are looking to water proof a smaller area, using a hose and soaking the brick bit by bit from the bottom up, and waiting fifteen minutes every couple of feet, you may be able to pinpoint where the water is entering.

The number of calls that we receive from customers who call us the day after a chimney fire saying that their neighbors came knocking on the door to let them know that their chimney is on fire is concerning but not necessarily surprising for those in the industry. When certain conditions exist, a chimney fire is able to burn slowly as opposed to explosively making it such that the fire is hardly detectable from people inside the home. A chimney fire that burns explosively is what is generally described as a chimney fire. When a rapid burning fire occurs in the chimney there is a loud rumbling noise similar to a freight train.

<——–This one cracked the chimney right up  the middle .

Creosote in the chimney flue makes having a chimney fire of any kind more likely.

“Creosote comes in Three forms”

Creosote Buildup

<——-  Look down this chimney flue , and it stinks

 

1st Stage: Flaky, Dusty . . . This type of creosote can be easily removed with a chimney’s sweep brush because of the looseness of its deposit pattern.

2nd Stage: Crunchy or Tar like . . .This type of creosote is more difficult to remove and often requires stiffer brushes or even a scraper to remove.

3rd Stage: Glazed, Gummy or Hard . . . This type of creosote acts like candle wax. When stage 3 creosote gets to a certain temperature it drips

 

Creosote Build Up
There has likely been a chimney fire which caused the creosote on this cap to melt like candle wax and clog the flue system.down the walls of the flue and dries a hard, glossy, black mass.

Excessive buildup of stage 1 creosote makes for plenty of fuel for a slow burning chimney fire to occur up in the top portion of the chimney. When glazed creosote occurs, there is a good chance that a chimney fire has also occurred. When chimney fires occur, the flue tiles often crack vertically due to the rapid temperature change in the flue system. The stage 3 creosote drips down covering such damage and hardening, hiding a potentially dangerous situation. Creosote has the tendency to build up at various parts in the chimney itself, specifically the in the smoke chamber and near the damper.

Creosote buildup, no matter what stage it is in, has a very ” pungent odor ” and has the ability to permeate an entire house, especially if your chimney also has drafting issues. Any slight downdraft will force these odors into the home.

 There are AntiCreo-Soot chemicals on the market that work to reduce the smell and volume of creosote in the chimney, but these often take many applications in order to eliminate the smell entirely.

Water Repellent
These water repellents from the ChimneySaver line form semi-permeable membranes to protect brick without trapping vapors.

Winter is a very hard time for your brick. While you sit inside nice and warm, perhaps around a fire in the fireplace or comfortably warmed by a different heating appliance, the brick on the exterior of your home are experiencing every change in temperature, from the drops below zero to those days where the temperature can’t decide if it wants to be above or below freezing.

All of these circumstances affect your brick in that the water that is naturally found inside of them in the form of water vapor will freeze and thaw according to the temperature, causing damage to

Freeze Thaw Damage
This is an example of the damage that can occur from continual freezing and thawing.

the brick. The way that this water damages your brick is that as water freezes, unlike other elements on Earth, it expands to a larger form than in its gaseous or liquid state. Think if you put a water bottle full to the brim of water in the freezer. When you come back to it, that water bottle’s lid will likely have popped off because the volume that the ice takes up is larger than the volume that the water took up.

This principal attribute of water is the reason why so many companies have spent so much effort in creating products to protect the brick and other masonry surfaces on your home. The

Breathable Water Repellent
This illustration shows the benefits of ChimneySaver Water Repellent’s formula.

cracks in which water lies or the pores inside the brick in which water vapor is found work much like the bottle in the freezer. As the water expands it needs somewhere to go so it pushes and pushes on the brick or other masonry until it has the room it needs, which often means damage to the brick.

To prevent such damage from occurring it is prudent to have applied water repellent to your brick, especially to your chimney which is subjected to more of the elements than the rest of the home. A good water repellent is deep penetrating instead of film forming. What does this mean? It means that a good water repellent is not going to merely sit on the surface of the brick you are applying it to and form a barrier, it is going to sink deep into the brick and form a semi-permeable barrier. This barrier will allow water vapors that are trapped inside the brick to be able to exit but still prevent water molecules from entering. Spalling (the faces of the brick popping off) occurs when water vapors inside the brick are trapped in. They expand and contract continuously until the front of the brick has come off to allow for this process to keep occurring.

Relining your chimney gives you quite a few options for cutting corners. When relining your chimney, one corner I have seen be cut is no insulation being put around the new chimney liner. This is a huge mistake, and most chimney professionals would agree. In order for most reline jobs to meet UL Listing Standards, insulation is generally required. This, of course, can vary by manufacturer,

Chimney liner insulation kits come with everything you need to insulate your new chimney liner.

but many reputable chimney liner dealers operate this way, and not without good cause.

Chimney Liner
Laying your insulation blanket out and spraying adhesive so that it can be rolled up easily is the best way to install the insulation.

A chimney liner which is insulated provides benefits that go beyond merely meeting UL Listing Standards. Chimney liners that are insulated helps to prevent the extremely high temperatures found in the flue system from spreading through the masonry chimney itself to combustibles. Similarly, the insulation keeps the flue system itself warm such that the gases are able to draft up and out of the chimney at peak efficiency. An insulated chimney has, through observation over time, less creosote than a non-insulated chimney. Because the chimney flue stays warmer when insulated, creosote in its vapor form has less of an opportunity to rest and cool on the liner’s surface. By preventing condensation of creosote, you prevent creosote build up.

What type of material should be used to insulated a chimney liner? We recommend foil face insulation blankets made of ceramic fibers. These blankets are wrapped directly around the pipe, taped at the seam with foil tape, and then covered with a wire mesh which prevents the insulation from being damaged as it is lowered down the chimney. The ceramic fibers are the main insulator in this system, but the foil facing also is an insulator.

It is convenient to buy all of your insulationsupplies in a kit. A kit should include the actual blanket, tape, the wire mesh, clamps for attaching the mesh, and spray adhesive. Often times you can purchase your liner kits precut to fit the length and diameter of the flue system that you are going to insulate. This makes the process very smooth and saves you additional work as well as waste. By purchasing only the amount that you need, you are able to save money in addition to time.

Bricks on homes need repaired all the time, however, the bricks on the chimney are exposed to more of the elements than the rest of the home and therefore are often the most damaged bricks on the home. Over the winter, temperatures in most parts of the country dip below freezing and then back up again frequently. Vacillating temperatures are prime for further damage to brick that has any existing damage due to freeze thaw damage.

What is Freeze Thaw Damage?
Freeze thaw damage occurs when water either naturally found in the brick or water that has pooled and is left behind from rain or snow freezes and thaws. When water freezes, it expands. This expansion can cause the brick to crack, or crack further if water is sitting in an existing hairline crack. There is a small percentage of water naturally found in the brick and if these vapors freeze and

thaw repeatedly spalling may occur, which is where the faces of the bricks actually pop off.

Having any cracks on your chimney going into the cold season, you run the risk of these cracks getting even worse. Even hairline cracks run the risk of become a deep, damaging crack, so sealing your cracks with a silicon treatment is a great idea. CrackMagik, a product by ChimneySaver, is a breathable silicon elastomer which can be painted on to cracks or small holes using a paint brush. Sealing these cracks prevents them from worsening over the cold months and causing damage to the point where bricks must be removed and replaced or portions of the chimney must be rebuilt entirely.

After sealing any cracks in the brick or mortar on your chimney using a flexible silicon sealant, it is prudent to waterproof the entire chimney to prevent any new hairline cracks from forming or water damage occurring anywhere else on the chimney. Water repellent selection, especially before a very cold season, is very important. As I already mentioned, there is a certain small percentage of water naturally found in brick, so sealing all of that water vapor inside will actually increase the likelihood of the brick spalling.

Water repellents which form a non-permeable membrane over the brick (meaning that the vapors found inside cannot escape) will actually wind up causing more harm than good in the long run in most cases. I recommend water repellents which penetrate deep into pores of brick, allowing vapor to move out of the brick but water droplets to stay safely on the outside. The type of water repellent you select along with whether or not you deem any existing cracks on the chimney problematic are all serious considerations any homeowner should take prior to the cold season.

Painting the brick on your chimney is always, without a doubt, the beginning of a painful, time consuming process for any homeowner who decides to take the painting plunge. Say you aren’t too fond of your brick color or the brick on a portion of the home is starting to look less than desirable, it may seem reasonable to simply slap up some paint on top of it and call it a job well done. What homeowners don’t realize  is that their freshly painted chimney immediately starts to deteriorate as soon as the paint has dried, and every rainfall only speeds up the process.

Painted Brick
Painted Brick

In brick there is naturally found a small percentage of moisture which moves in and out of the brick’s pores. When you paint the brick you block the pores so that the moisture has difficulty leaving. Although it may seem like you are preventing water from damaging the brick at all by blocking the brick with paint, what is actually happening is much worse. This moisture trapped underneath this layer of paint will slowly but surely make its way through the paint. This causes hairline cracks to appear in the paint which allow external water from rain or snow to enter the picture. This water is trapped beneath the paint which actually causes damage to the brick itself! Now not only are you dealing with unattractive, peeling and cracking paint, you also have a structural issue in that the integrity of the brick has been compromised.

There are many options you can take to improve the look of your brick without painting over it. For brick that has been stained, say by rust, dirt, etc., using a brick cleaner is a cheap restoration. Although in years past muriatic acid was the way to clean your brick, there are now safer cleaners available on the market that are less harsh than this acid which can actually stain the brick further when being used. The ChimneySaver Brick and Mortar Cleaner is a product that my servicemen use, especially on harsh chimney stains which can come from an aluminum cap rusting or a black painted chimney caps.

If the reason you are painting over your brick is because it is chipping off or breaking or the mortar joints are falling out, do not paint the chimney! Painting the chimney will only speed up the rate at which your chimney deteriorates. If this is the case, consult a professional to give you an estimate for repair on your chimney.

Chimney protection can seem like a daunting task, but taking the extra step with every repair you do to you chimney will add up over time. Going that extra mile in protecting your chimney each time an issue arises, as with all other aspects of good home ownership, will pay off.

Spalling Brick
After repairing this brick, applying a quality, breathable water repellent will help to prevent the need for this repair again.

Take, for example, a brick repair project. It could be located anywhere on the home. You may need to actually cut out and replace brick on the home or merely repair mortar joints by tuckpointing or even simply seal some cracks in the brick using a silicon sealant and. No matter what type of repair is necessary, the fact that the repair was needed at all is an indication that the brick there is vulnerable to more damage for whatever reason. It might be that the design of the home has water running over this particular spot in excess, causing damage, or water may be able to pool there, causing freeze thaw damage. Whatever the reason may be, it is important to protect this repair and the surrounding brick which is also at risk by using a water repellent over the area. ChimneySaver water repellents come in various formulas specially formulated for your specific chimney need. The reason we recommend this brand over other water repellents is because it has been formulated to withstand increased weather damage because the chimney is offered no protection like the rest of the structure of the home; it reaches up above the roof line.

Another place a homeowner should not cut corners is when installing a chimney cap. By spending a little extra money on a stainless steel chimney cap as opposed to any other metal or a black painted chimney cap, you will save yourself extra work down the road. A black painted chimney cap will almost always cause stains on the chimney itself. Over time heat from the chimney combined with the elements will cause some of the color to

run down the chimney and stain it. Metal chimney caps that are not stainless steel will almost always rust out before the end of their useful life. This presents the danger of rust

Stainless Steel Chimney Cap
When installing a chimney cap in this or any other style, you want to consider using a bit of silicon to prevent it from flying off in strong wind.

staining the top of your chimney and the danger of the chimney cap itself losing its integrity and allowing critters to enter it. A little bit of adhesive or silicon goes a long way when installing a chimney cap. Using just a little will further prevent the cap from flying off on a very windy day, saving you the hassle of either having to go up and reinstall it yourself (if it was not damaged when it hit the ground) or having to pay a professional to come out and do it for you.

As you can see, a little goes a long way, whether it be a little extra cash for a quality product or a little extra labor in the form of applying a bit of silicon when installing your cap or preventing further damage with an application of water repellent over a repair. These are all things to consider when you are going through any home improvement.

Proper maintenance of your chimney’s crown will save you costly repair down the road. By getting up on the roof yourself to look at the crown or having your chimney professional doing so when you have your chimney swept and inspected you will not only save chimney repair but prevent damage further down the chimney as well. A crown that is intact and contains no cracks will protect the brick below it. ChimneySaver is a tried and true line that is specifically formulated to protect chimneys. Since chimneys are located above the roofline they receive no protection from the elements. They get the full force of any rain or snow and more prone to freezing and thawing damage because they are located higher up than the rest of the home.

Crown Repair
Application of CrownCoat is the image on the left and the application of CrownSeal is the image on the right.

For minor crown repair, you want to use a crown resurfacing product. The ChimneySaver line features two kinds of crown resurfacing products, CrownCoat and CrownSeal. CrownCoat is the newer product of the two and requires a thinner application than CrownSeal. For application of CrownCoat, you need to only do two thin layers over the entire chimney crown which will dry in four hours. Use a paint brush when applying the product to the crown, and do not apply CrownCoat to vertical surfaces, only horizontal. CrownCoat has a 15 year warranty when applied by a professional. CrownCoat is also available in an advanced formula which can be applied in cold weather. Cold

Crown Repair
This CrownCoat special formula will cure in temperatures below freezing.

Weather Crown Coat is similar to the original product but is capable of curing in temperatures below freezeing due to new technology. When the temperature is below freezing the product actually cures more quickly than it would in temperatures that are cold but not freezing.

CrownSeal is the older of the two products and requires one thick application. We recommend this for situations where there are imperfections that need to be hidden. The thicker application will help. This product should be applied with a grooved trowel and brush and due to its thicker application takes 24 hours to dry completely. CrownSeal has a 10 year warranty when applied by a professional, which is not as long as CrownCoat. CrownCoat and CrownSeal are both tintable with mortar dye, are available in 2 and 5 gallon containers and should be applied in temperatures above 45 degrees Fahrenheit (with the exception of Cold Weather Crown Coat.) Decide which product is most conducive to your condition, factoring in the frequency of rain that your area experiences and the level of damage that your chimney crown has incurred. Also, consult with a chimney professional if you have any questions regarding the care of your crown or other parts of your masonry chimney.
