NH Chimney liner repair can vary greatly in price due to a number of factors including roof access and whether or not the current defective lining system needs to be removed. However, to give a rough range of prices, an oil chimney liner replacement in NH will usually run anywhere from $1900-$3000.
A wood stove chimney liner replacement is a bit more expensive because the current wood stove lining system nearly always needs to be removed. The price for a wood stove lining system replacement in NH is generally between $2200-$3500.
Fireplace chimney liner replacements usually start around $2750-$4000. Fireplace lining system repairs are by far the most expensive because fireplaces require a very large lining system.
It is important to repair a chimney liner in NH because NH is a naturally cold state where chimneys are used far more often throughout the year than many other states in the country. Because we use our chimneys so frequently in the cold state of NH, it is very important that we keep our chimneys as safe as possible.
Using a chimney with a defective chimney liner is not safe whatsoever. Using a chimney that needs a chimney liner repair is inviting carbon monoxide or a chimney fire into your home depending on the appliance venting into the chimney. Replacing a chimney liner can certainly be a relatively expensive project, but keeping toxic gasses and potential chimney fires contained inside of a fully functioning chimney liner is well worth it. With a defective chimney liner, a chimney fire has a better chance of spreading into a structural fire because it is not contained inside of it's intended lining system. With a proper chimney liner, the fire will not be able escape the lining system, and therefore, the chances of the flue fire extending into a structural fire are greatly reduced.
A chimney liner repair begins with a chimney inspection performed by a certified chimney sweep. A certified chimney sweep is trained to look for potential defects in a chimney liner with the goal being to keep the chimney as safe as humanly possible. When a certified chimney sweep finds cracks, gaps, or other defects in the chimney liner, they know that the lining system is not safe for further use and they will need to recommend a replacement.
The first thing a certified chimney sweep will do when they realize the chimney liner must be replaced is gather all required measurements for the chimney liner including properly sizing the chimney liner for the appliance type. Once the chimney liner has been sized and all appropriate components have been measured for length, the certified chimney sweep will order the chimney liner replacement parts.
Parts can take a varying amount of time to become available based upon the time of year. During the fall, which is the busy season in the chimney industry, parts can take up to a full month to come in. For this reason, we recommend having chimney repairs and maintenance performed in the spring.
Once the parts for the repair become available and we receive them, the installation process begins. A chimney liner installation process is different in every case, but it will always begin with setting up some sort of safe roof access. We need to be as safe as possible while bringing the large chimney liner onto the roof. Sometimes these liners are up to fifty feet long!
Once safe roof access has been established we will begin by opening up the thimble or damper area depending on what kind of liner is being installed. (All floors will be protected in our work area to avoid staining on the carpets where applicable) Once we have a workable area toward the bottom of where our liner will terminate, we will begin our work toward the top of the chimney.
At the top of the chimney we will either begin to break the current clay flue tiles out, or begin to drop the liner down the existing flue tiles. We will always break the existing flue tiles out of the chimney if the tiles have creosote on them that could not be easily removed in order to prevent a chimney fire from happening on the outside of the newly installed lining system. We will also remove the current, defective clay tile flue system if there is not enough room inside of it to fit a properly sized, stainless steel lining system.
Once the clay flue tiles have been removed, (when applicable) we will drop the new lining system down from the top of the chimney. We will, at times, use a pulling cone and a rope to help direct the new chimney liner to the prepared hole at the bottom of the chimney. Once the new chimney liner is all the way down the chimney to the prepared hole at the bottom, we will connect the new chimney liner to the appliance using only approved components designed for such use. (fireplaces are done a little differently) Once the bottom is terminated properly and the new chimney liner is properly connected to the appliance, we will use our approved top kit, which includes a rain cap, to properly terminate the chimney liner at the top of the chimney. At this point, the new chimney liner has been successfully installed, and we will begin cleaning up. (The installation process takes anywhere between four and twelve hours.) Cleaning up involves taking all the old clay lining system with us in a series of five gallon buckets when applicable. It also incorporates cleaning all floors in our work area with a high powered HEPA filtrated vacuum designed to prevent the smallest dust particles from getting into the air.
Once clean up is complete, the job is done! We will remove our scaffolding from the roof and/or any other roof safety equipment we have set up, and we will be on our way. If you have any specific questions about our chimney liner installation process, please don't hesitate to ask!
Anything Chimney insulates all chimney liners that will be venting solid fuel. The reason being is that the insulation around the chimney liner will help prevent large amounts of creosote from building up inside of the chimney liner. The insulation also makes the chimney liner "zero clearance," which means that even if there is a combustible touching the chimney, in the event of a chimney fire, the fire will be contained inside of the chimney lining system. An insulated chimney liner will, by far, outperform a non insulated lining system, and it is, by far, much safer. That is the reason that Anything Chimney will only install insulated chimney liners for solid fuel burning appliances and fireplaces.
The photo on the right (above this section on a mobile phone) is of an insulated chimney liner. The metal on the outside is just a protective layer that keeps the layer of insulation inside of it from becoming damaged. Inside of the protective layer and the insulation layer is the actual chimney liner. These kinds of chimney liners are rated for "zero clearance."
There are three primary reasons that a chimney liner will need to be repaired or replaced in NH. The first reason, and in our experience, the most common reason is that the chimney is venting oil. A chimney liner that is original to the home and constructed of clay flue tiles venting oil does not last very long at all. The reason for this is that oil is extremely corrosive when it burns. When oil burns and the gasses produced from it burning are sent up the chimney and mix with the moisture in the chimney, the gasses actually create sulfuric acid. That sulfuric acid produced inside of the chimney will destroy the chimney from the inside out over time. The gasses begin destroying the chimney by progressively weakening the structural integrity of the clay flue liner. Once the integrity of the liner is compromised the clay flue tiles will begin a process known as spalling. A spalling chimney liner can be easily recognized because it appears that the chimney liner is flaking and there will be large, usually orange colored "chips" in the chimney's ash dump underneath where the oil boiler's stovepipe enters the chimney flue. After the clay lining system begins spalling it becomes easier for cracks to form and for the mortar joints in between the flue tiles to be eaten away. (This entire process happens a lot faster if there is not a rain cap on the chimney as well.) Once there are cracks in the chimney liner, gaps in the liner sections, and spalling clay flue tiles, there is no doubt in the world that the chimney liner must be replaced, because the next place the corrosive oil fumes are going to eat away at is the actual brick structure of the chimney. This can cause expensive masonry repairs in order to save repair the structural stability of the chimney itself, and it can also cause a carbon monoxide risk.
Oil fumes can actually eat through some forms of steel chimney liners as well, that's why it is so important to have a certified chimney sweep install the replacement chimney liner when it is necessary to do so. Some forms of metal, and some thicknesses of metal can not withstand the damage that is caused by the sulfuric acid produced by burning oil.
The second reason that a chimney liner would need to be repaired in NH is if the chimney liner underwent a concentrated high heat event. A simpler term for this type of event is a chimney fire. If a chimney liner goes through a chimney fire there is a high probability that the chimney liner has become defective over the course of the chimney fire. This is especially true when it comes to clay chimney liners. Clay chimney liners will easily crack when faced with a concentrated high heat event like a chimney fire. Once a chimney liner has cracked, it is no longer able to contain the by-products of combustion and must be replaced per NFPA 211 standards.
The third most common reason that we see chimney liners that need to be replaced in NH is when there are gaps in the flue tiles. (excluding oil burning flues) The reason these gaps tend to appear in between the flue tiles is often because an incorrect form of mortar was used when constructing the original clay flue liner. When building a clay flue liner, a more expensive version of mortar known as refractory, non water soluble mortar is supposed to be used. When this form of mortar is not used it can cause the mortar joints to flake and wash away over time creating holes and gaps in the lining system. (This process is accelerated when their is no chimney cap present) These holes and gaps make the chimney liner incapable of containing the by-products of combustion and per NFPA 211 standards, the chimney liner must be replaced.
Chimney pointing, also called chimney repointing, chimney re-pointing, or chimney tuck pointing is the act of removing deteriorated mortar from in between bricks or blocks, and replacing that mortar deteriorated mortar with new, fresh mortar.
Chimney pointing is important in NH because chimneys in NH are constantly freezing and thawing. A chimney that freezes and thaws, when it is not already waterproofed will create cracks and gaps in the mortar joints in between the bricks above the roof line. Over time these cracks and gaps will get worse, and eventually the chimney structure will need to be rebuilt above the roof line. To prevent the chimney from needing to be rebuilt, we recommend pointing the chimney, and then waterproofing the chimney structure.
Chimney pointing is done by using a grinder with a specialized wheel designed for chimney pointing. The wheel spins at such a rate that when it is pressed into a mortar joint, it turns the joint into a dust that is then sent into the air. Once all applicable joints are "ground out" using the grinder, we will mix new mortar that will be inserted into the gaps between the bricks in the chimney. This new mortar will then cure in about 24 hours, and should last a minimum of ten years if the chimney structure is then waterproofed.
Chimney flashing repair is either replacing the current, defective chimney flashing or using a flashing sealant to ensure that no moisture can get past the chimney flashing and into the attic of the home.
The reason it is important to repair chimney flashing in NH is because the chimney flashing is the only thing preventing rain and snow from falling directly into your attic. Chimney flashing is usually made out of lead in NH and acts as a water repellent skirt around your chimney that forces water to find another place to go other than directly into your home.

Chimney crown repair is the process of replacing the cement slab at the top of the chimney with a fresh slab of cement with the goal being to prevent moisture from falling down the chimney void, as well as avoiding the bricks at the top of the chimney from soaking up the rainwater and becoming damaged over time. Chimney crown repair is an important part of preventative chimney maintenance.
Chimney crown repair is important in NH because a defective chimney crown creates an active water penetration point into the chimney. A defective chimney crown also creates a water absorption point into the top courses of chimney bricks. When water gets absorbed into the top courses of chimney bricks, it will begin to freeze and thaw during the colder months in NH. When water freezes and thaws the top courses of chimney bricks, it can lead to the brick faces popping off. (This is known as spalling bricks) When this happens, the defective bricks will then need to be replaced.
When water is able to enter the chimney through the defective chimney crown, we end up with water at the very base of the chimney, usually in the basement of the home. This rainwater can cause accelerated degradation to the base of the chimney in the basement, which can lead to more expensive repairs down the line in order to preserve the integrity of the chimney structure.
In summary, repairing a chimney crown can save a homeowner a lot of time, aggravation and money down the line, and it is relatively inexpensive to do.
NH chimney crown repair can cost anywhere between $500 and $1200 dollars for the repair itself based upon the size of the chimney crown that needs to be replaced. Roof access is also a factor when talking about chimney crown repair. If staging or a man lift is necessary to complete the chimney crown repair, there could be additional charges.
Chimney waterproofing is the act of applying a specialized waterproofing formula specifically designed for chimneys to the entire chimney structure where the chimney is exposed to the outside elements.
When chimney waterproofing is done properly, it acts as a breathable barrier that allows internal water vapors to vent out of the chimney bricks, but it does not allow new moisture to enter the chimney structure. Rain water and moisture will simply bead off of the chimney instead of absorbing into the chimney the way that it normally would. This protects the chimney against the freezing and thawing damage that often becomes prevalent in cold NH weather.
The reason that a chimney should be waterproofed in NH is to preserve the life of the chimney. The brand of chimney waterproofing formula available to professionals, and the brand that Anything Chimney personally uses comes with a ten year warranty. This means that a chimney in NH only needs to be waterproofed once every ten years.
What will happen if a chimney is not waterproofed is more rapid degradation. A chimney that is not waterproofed will absorb moisture that will freeze and thaw during the colder winter months in NH. Because of this, Some bricks may become defective and need replacement.
To remedy the damaging effects of the freeze thaw cycle, we always recommend that a chimney be waterproofed if it has not been waterproofed in the last ten years.
Chimney waterproofing in NH will cost anywhere between $300 and $1200 depending on the size of the chimney that needs to be waterproofed. Roof access is also a factor when it comes to chimney waterproofing, and if staging or a man-lift is needed, there could be an additional charge.
A chimney should be rebuilt in NH if there are full, visible gaps between the mortar joints, the brick faces are falling off, or the bricks are completely loose due to a bond break between the bricks and the mortar.
A NH certified chimney sweep is trained to determine whether or not a chimney needs to be rebuilt in NH. If you see loose bricks towards the top of your chimney, or something just doesn't look the best up there, please, feel free to give us a call. Our certified chimney sweeps would be happy to give you an thorough and honest chimney inspection.
A Chimney rebuild entails removing all of the loose bricks and bond broken mortar until we are building on a structurally sound chimney structure. Once we have established a solid chimney base, we begin building with new bricks and mortar until the chimney reaches code compliant height. Code compliant height is three feet out of the roof line, and two feet above anything within ten feet of the chimney. Along with rebuilding the actual brick and mortar that makes up your chimney structure, we will also, at times, need to replace the chimney flashing, as well as the chimney crown. The chimney crown will always need to be replaced. The chimney flashing will need to be replaced as deemed necessary by your chimney professional.
The cost to rebuild a chimney can vary greatly based upon how much of the chimney needs to be rebuilt, whether or not the flashing will need to be replaced, whether or not we will need to be building inside of an attic, and the difficulty of the roof. If your chimney needs to be rebuilt in NH, I would be prepared for a bill of $3000 at the bear minimum. Prices can increase greatly based on the factors listed above. Because of this, we strongly recommend keeping up with basic chimney maintenance. Maintaining a chimney can help to avoid the major repair cost of rebuilding a chimney.
