Types of Masonry Restoration

Notice problems in your chimney masonry? Call us and we’ll do the necessary repairs so your chimney will look and function as good as new.

If you have a masonry chimney, you should know that the Chimney Safety Institute of America claims water is your chimney’s greatest enemy because if it penetrates into your masonry joints, it can cause all sorts of expensive repair work, such as structural damage. Another victim of water damage is your chimney crown. To repair this water damage as well as to prevent water damage from even happening, you will need some sort of type of masonry restoration work from a professional chimney company like Santa’s Friend Chimney Service. We have experienced masons on hand that can perform several types of masonry restoration work, and we would like to tell you more about the types of masonry restoration work we provide.

Repointing/Tuckpointing

To provide a better understanding of repointing, the Masonry Magazine, the official publication of the Mason Contractors Association of America, states that looking at the differences between the 100-year old definitions of the masonry terms “pointing,” “jointing,” “repointing,” and “tuckpointing” will give you a better idea of what repointing means today.

• Pointing – The definition of pointing is the placement and careful tooling of a mortar joint between bricks and stones, and contrary to jointing, this process scrapes back the mortar joint several days after the completion of the brickwork.
• Jointing – Jointing is what bricklayers do today, the process of finishing the joint along with the brickwork being completed.
• Repointing – Typically the type of restoration work done on older mortar, 100 years ago, repointing meant replacing a failed mortar joint, which happened about once a century.
• Tuckpointing – The word “tuckpointing” referred to a specialized application of pointing where the bricks were first sanded to a smooth surface and the original mortar joint is masked with a thin strip that matched the brick in color. Then, the joint was meticulously shaved down to match exactly the other joints in the chimney, and a fine, usually white mortar was tucked over the lines and finely manicured to look like no repairs had ever been done.

Today, “repointing” refers to repairing damaged mortar joints by filling in the gaps and holes created by water penetration, and “tuckpointing” refers to replacing deteriorated mortar with new mortar. The experienced and trained masons at Santa’s Friend Chimney Service are able to provide both types of masonry restoration to repair spalling and other damage due to water penetration of your masonry joints.

After explaining the different types of masonry restoration we provide, Santa’s Friend Chimney Service would like to tell you about a water penetration prevention service we offer:

• Waterproofing – Using specially formulated materials that prevent water from penetrating into your bricks and masonry joints but allow vapors to pass through your chimney, our technicians have been applying the Chimney Saver Water Repellent for the past 20 years successfully to chimneys all over the Central Mississippi area. Your chimney will be protected from water penetration that causes the damage that needs masonry repair work.

If you have loose bricks and chips in the mortar of your chimney, contact Santa’s Friend Chimney Service today to schedule an appointment with one of our experienced chimney masons. We would be happy to provide our masonry restoration services to you.

All About Liners

We recommend an annual chimney inspection for many important reasons. One of the most important is so that we can inspect the quality of your chimney’s liner. The liner protects the exterior wall of your chimney.

What’s Blocking Your Chimney?

A clogged up chimney flue can mean big trouble. Make sure there’s nothing blocking your chimney by having it swept.

A fireplace can be a wonderful addition to any room in the house where the family might gather, providing warmth, light, and a cozy ambiance. However, a fireplace system has to be carefully maintained to make sure that they common problems that affect chimneys don’t impact the safety and beauty of your family’s favorite gathering spot. We as homeowners owe it to ourselves to remain constantly vigilant as far as the condition of any part of our homes are concerned. Like every appliance or piece of furniture we own, a chimney requires just as much attention; one could even argue that it requires more attention.

The Dangers of Creosote Buildup

So what exactly is creosote, and why is it dangerous to allow it to accumulate inside your chimney? Creosote is a sticky chemical residue that forms when wood is burned at low temperatures and is capable of building up to dangerous levels within your chimney. More creosote is formed from burning unseasoned softwoods in your fireplace than properly seasoned hardwoods. The residue begins as unburned oil in the form of gas; as it moves up the chimney, the oils build up into a coating inside the chimney as they begin to cool. This buildup is extremely flammable!

The residue can become quite thick over the course of a single season. Depending on the internal dimensions of your chimney, this can really restrict the flow of air, which can cause smoke to build up in the fireplace as well as in your home. This reduced airflow can also cause cooler burning fires because they’re not able to get the requisite amount of oxygen for increased combustion; all of this results in, you guessed it, more creosote buildup in your chimney. It becomes dangerous when it is allowed to accumulate in your chimney, as it becomes a fuel source for a possible chimney fire. The build up of creosote cannot be avoided completely, however, burning small, hot fires and using dry, seasoned wood can minimize the buildup.

There’s a What Living in my Chimney!?

If you are hearing noises in your chimney it may be one of two situations: a wild animal (such as a raccoon) is using your chimney as a den; or an animal (such as a squirrel or a bird) has fallen down the chimney and cannot get back up. Under absolutely no circumstances should you try to smoke an animal out of your chimney – you will only succeed in burning and/or killing the animal! Wild animals frequently mistake uncapped chimneys for hollow trees, and they have no idea that the “tree” is connected to your home! In contrast to hollow trees, however, the inside of a chimney is quite slippery, and raccoons seem to be the only animals capable of climbing up and down it.

One way to tell the difference between a denning animal (raccoon) and an animal that’s stuck (squirrel or bird) is by listening to the noise that the animal makes. An animal that is stuck is often frantic, and will scratch at the damper or flap its wings repeatedly in an effort to get out. If the damper is not closed, the animal may fall down into the fireplace, and even if he is able to get back up above the damper or onto the smoke shelf, it is important to recognize that this animal is unable to climb the entire length of the chimney. On the other hand, if the animal is using the chimney as a den site you may occasionally hear movement, as well as the sounds of wild animal babies calling out to their mother. The noises follow a more predictable pattern, and often occur only a certain times of the day.

While the firebox of your beloved fireplace can be easily seen and therefore monitored, the chimney itself commonly faces a number of troubles that are often caught only by a chimney professional during the annual chimney system inspection and sweeping. These things will help to ensure the safety and continued functionality of your fireplace and chimney for many years to come. You can always come to Santa’s Friend Chimney Service with any of your questions or needs. Our staff is always here to help.

Keep the Water Out

Keep A Focus On Keeping Water Out Of Your Chimney

Along with having your chimney inspected every year and making regular chimney sweeping appointments to stay ahead of creosote, taking precautions to fight off encroaching water is one of the most important things you can do to keep your chimney system trouble-free.

Call us today and lets start making sure your chimney is working at its optimal level.

A healthy amount of the time, when Santa’s Friend Chimney Service is called in with a chimney repair need, water is the culprit behind the damage. That’s partly because water can so easily take advantage of even the smallest chink in your chimney’s armor, slipping into the tiniest crack or gap and then, during cold snaps, expanding as it freezes and making a small problem into a big one. The fact that moisture is almost omnipresent in Central Mississippi doesn’t help either — moisture, over time, can just wear at masonry and metal.

But something to consider, too, is prevention. A lot of times, we don’t think about moisture’s effects on our chimney system until we’re dealing with a leak. But a few key things can help you minimize leaks and moisture damage — or even avoid them altogether.

Make Sure You Have A Properly Sized And Installed Chimney Cap

A chimney cap isn’t just adornment (though it does make a chimney look nicer and more finished). It helps to keep precipitation from coming directly into your flue opening, and slowly wearing away at the flue liner or masonry. If your cap is damaged or missing, Santa’s Friend can install a new chimney cap that’ll bring much-needed protection to your flue.

Consider Chimney Waterproofing

We highly recommend Chimney Saver’s chimney waterproofing sealant. It stops water from penetrating your masonry, but still allows that masonry to expel vapors from its interior, as it was designed to. That protection not only helps you avoid leaks, but adds to your masonry’s longevity too (and in that, minimizes your headaches). Santa’s Friend techs can tell you more about this product, and apply it to your chimney.

Remember When We Mentioned Chimney Inspections?

Keeping up with your annual inspections is key to minimizing chimney leak problems. It’s not uncommon for the parts of your system designed to fend off water — like the chimney crown at the top of your flue or the flashing installed where the chimney and the roofline meet — to develop small imperfections. Your crown may crack under the strain of sun and rain, and the caulking around your flashing can loosen or come off. When you have your chimney inspected regularly, Santa’s Friend can catch those small issues before they get worse, and make the repairs to avoid a serious leak.

If you have any worries about moisture getting into your chimney, call Santa’s Friend. We’re always here to help with information, service, repairs, installations — anything you might need for the care and maintenance of your chimney system.

Log vs. Sweep

In our lives, we applaud each other for working late, laugh at those who don’t, and measure our self-worth in time stamps.  Meanwhile, those who take the proverbial “easy way out” are ridiculed, criticized and/or passed over for promotions.  An online search returns pages of blogs explaining how to kick the habit of taking it easy.  By all accounts, taking the easy way out seems harmful and counterproductive.  Why, then, do so many of us seem so drawn to the path of least resistance?  If the hard route leads to more profitable outcomes, why aren’t more people willing to go that route?  Why do we tend to look for the easy way out of a situation?

Chimney Sweeping Logs: The Easy Way Out   It’s easier that way, for one.  Physics says that the path of least resistance is generally the one taken.  The decision on the best method for cleaning your chimney should not be one in which you opt for the easy way.  There are all sorts of advertisements for chimney sweeping logs (CSLs) flooding the marketplace today.  These products claim to do the work of a chimney sweep, all for a price of around $15 per log.  Sounds too good to be true, huh?  If you answered yes, you are correct.

Using a log that claims to rid your chimney of creosote may cause more problems than it promises to solve.

What the CSLs Actually Do   It really isn’t the logs that are supposed to do anything; it is the chemicals and minerals they’re impregnated with that do all of the work.  When a CSL is burned, the chemicals and minerals are carried up the flue by the rising exhaust gases.  After entering the flue, they attach themselves to the creosote in your chimney and, over the course of several subsequent fires, break it down, causing it to crumble away from the chimney walls.

What’s in a Name   The name, CSL, is a bit misleading.  One would expect a product called a chimney sweeping log to actually sweep the chimney, or at least perform an equivalent function.  According to the Chimney Safety Institute of America (CSIA), the use of CSLs alone is not an adequate substitute for mechanical chimney cleaning and inspection because they do not provide for the same level of protection to your chimney system.  The CSIA mandates that all CSL manufacturers include a CSIA Accepted Product logo, including the following message: “When used according to the manufacturer’s instructions, this product is accepted by the Chimney Safety Institute of America.  For improved safety and home heating efficiency, CSIA recommends that all chimney and vented appliances be inspected every year by a CSIA Certified Chimney Sweep.”

This CSIA recommendation of regular chimney inspection and cleaning should be proof enough that CSLs aren’t all they’re cracked up to be.  If you want to spend your hard earned money on CSLs, please feel free to do so.  However, keep in mind that nothing can ever replace the services provided by a qualified chimney sweeping professional, including annual inspections and cleaning.

Your Chimney Liner’s Job

Your Chimney Liner Is An MVP

A chimney liner’s name doesn’t necessarily accurately convey the heavy lifting it does, or its supremely important role in your chimney system. We usually think of liners as add-ons — the shelf liners in our cabinets make things look a little cleaner, our jacket liners make things a little more comfortable, but it is different with chimney liners. If the chimney industry was going to be a little more clear about the importance of the chimney liner, we might call them chimney suits of armor for their protective properties, or chimney foremen for how they make the system work well.

The Chimney liner defends the exterior of your chimney wall from too much heat.

Overall, from the vantage point here at Santa’s Friend Chimney Service, a clean, strong chimney liner is definitely an MVP.

What Your Chimney Liner Does

If we were to boil it down, the chimney liner was developed to solve three key problems with chimney systems: the heavy wear-and-tear of heat and moisture on masonry; the susceptibility of building materials behind that masonry to heat and moisture; and the impeded draft that comes with inconsistencies in damaged flues.

First, your chimney liner provides protection. Whether your liner is made of terra cotta clay or stainless steel, it stands up to heat from your fire and potential moisture intrusion, allowing the masonry that makes up your chimney itself to stand stronger, longer. It also provides a needed extra layer of protection between the flammable beams and building materials in your walls behind the chimney, lessening the chances of a fire hazard.

Protection is just part of the chimney liner’s role, though. The liner also contributes immensely to performance, and draft. Air needs to flow smoothly up and out of your flue for the chimney to properly vent. If you think of your flue kind of like a straw, you’ll get a sense of why “smoothly” is so key. If you try to use a cracked straw, the pressure necessary to draw up becomes near impossible to create. The same kind of thing happens when cracks or gaps are present in your flue. A smooth, properly sized and intact flue liner creates a surface that encourages draft, and makes your chimney work more efficiently. (That’s part of why it’s so important to maintain your flue liner too, and to have damaged flue liners repaired or replaced as soon as possible.

A Flue Liner’s Size Is Important

A damaged clay tile liner is often the reason why Santa’s Friend Chimney Service technicians end up relining a chimney. But damage isn’t the only thing we look for when we’re inspecting a chimney system. A chimney needs to have a clean and intact liner in order to function correctly, but that liner also needs to be the right size. A flue that’s too big or too small for the appliance it’s venting will result in poor draft, increased byproducts and other issues.

To resize an incorrectly sized flue, we’ll install a stainless steel liner. These are great products that will last through years and years of use (when installed by a professional, most carry lifetime warranties).

If you have any questions about what a flue liner does, or what the process of relining or liner repair is like, Santa’s Friend is always willing to help. Give us a call with any questions, or to book an appointment with our experienced technicians!
