The Dangers of Chimney Sweeping Logs

When it comes to chimney maintenance, many homeowners are on the lookout for fast and easy fixes. One popular product on the market today that promises to clean your chimney is chimney sweeping logs. For about $20 these products seem like a fast, cheap, and easy alternative to having your chimney swept. However, chimney sweeping logs should never be used as an alternative to a professional chimney cleaning.

How chimney sweeping logs are dangerous

Chimney sweeping logs advertise themselves as an alternative to a professional chimney sweeping. As they burn, the smoke from the logs loosens creosote in the flue; as it loosens, the creosote then falls down and into the firebox where it can be easily removed.

While this may work in theory, it often fails when put into practice. Because most chimneys do not have straight, vertical flues, the loosened creosote often winds up trapped in the bends of the flue. Accumulated creosote can cause a number of problems; first, creosote is extremely flammable. Having accumulated creosote in the bends of the flue increases the risk of chimney fire if any stray sparks and embers were to travel up the flue. Second, large amounts of fallen creosote sitting in the bends of the flue can cause chimney blockages. These types of blockages can impact venting and cause gas and smoke to flow back into your home instead of up the chimney.

Using a chimney sweeping log can also make it more difficult to clean your chimney in the future. The fallen loosen creosote can accumulate in the smoke shelf above the firebox, one of the most difficult to reach and clean areas of the chimney. Because of this, a professional chimney sweeping is often needed to undo the effects of the chimney sweeping log.

Why chimney sweeping logs can’t replace a professional chimney sweep

Chimney sweeping logs might seem like a cheap and easy alternative to a professional chimney sweeping, but they can actually do more harm than good.

“I usually tell people using one of those logs instead of having your chimney cleaned manually is like chewing Dentyne instead of brushing your teeth,” said Allan Bopp of Bald Eagle Enterprises. “It may help a little, but it’s a poor substitute for the real thing.”

Even if they can help to loosen creosote, chimney sweeping logs cannot replace the benefits of having a professional sweep and inspect your chimney. A certified chimney professional is able to identify any signs of chimney damage or deterioration during a cleaning; oftentimes, spotting problems early can help prevent serious damage – as well as expensive repairs.

While chimney sweeping logs work in theory, using one can cause serious problems within your chimney system. Instead, skip the chimney sweeping log altogether and let a professional chimney sweep keep your chimney clean – and your family safe.

Water Leaks And Exterior Chimney Staining

While the bricks and mortar of your chimney is designed to withstand the elements, there is one force that can cause serious damage – water. Moisture can wreak havoc throughout your chimney system, causing leaks, rusty parts, and masonry deterioration. However, the presence of moisture can also show itself in unique ways, including chimney discoloration or staining. The following guide can help you identify the kind and source of your chimney staining – as well as how you can keep it from coming back in the future.

Water Leaks and Exterior Chimney Staining - Houston TX - Lords Chimney

Red or brown stains

If you have a prefabricated or factory built chimney, red or brown stains on the chimney chase are often the result of rusting. Long-term exposure to moisture – especially from puddles of standing water – can cause the galvanized metal found in many chimney chase covers to deteriorate and rust. The rusting chase top then causes dark red, brown, or orange staining to appear on the sides of the chimney. Rusted chase covers should be replaced with sturdier metals such as stainless steel or copper to prevent rusting from occurring again.

White stains

Crystalline or powdery white stains or discoloration are caused by a phenomenon known as efflorescence. Efflorescence occurs when water trapped in the masonry evaporates, leaving behind a concentration of white mineral salt.

Efflorescence is more commonly seen in areas where ground or rain water has a high salt content. Water from hoses, sprinklers, or rain can all cause efflorescence to occur. However, interior efflorescence may indicate that you have a leaky chimney; only small amounts of moisture are required to leave behind the mineral white chalky salt after evaporation.

Dark green stains

Dark green stains or discoloration is typically caused by the growth of algae on masonry. In order for this type of discoloration to occur, water must continually flow or pool over one area of the chimney structure. This type of long term exposure to moisture can foster an environment for algae growth – as well as mold or mildew – on the chimney.

What about inside?

While water can wreak havoc on your masonry outside, it can cause an equal number of problems indoors as well. One of the most common signs of a chimney leak is the presence of water in the flue, firebox, or on surrounding walls or ceilings. However, it can be difficult to tell the difference between a roof leak and a leaky chimney; because of this, you may want to have a certified chimney sweep have a look at the chimney before you or your insurance company pay to have the roof inspected and repaired.

Staining on your masonry could indicate that your chimney has a water leak. For more information on identifying chimney stains or to schedule a chimney inspection, contact Lords Chimney today!

Stinky Chimneys

Nothing can spoil a quiet evening spent in front of the fireplace quite like chimney odor. Unfortunately, chimney odors can also occur when the fireplace is not in use, leaving many homeowners scratching their heads as to what is causing their stinky chimney.

Chimney odors should never be ignored and are often the sign of a more serious chimney problem. Because of this, it is important to have a certified professional evaluate your chimney in order to uncover the source of the chimney odor and repair the source to keep it from coming back.

Causes of chimney odor

There is no one cause of chimney odor; because of this, it often takes the combination of a certified chimney professional and a chimney inspection to uncover the source of the odor. Below are some of the most common sources of chimney odor, what causes them, and how they can be prevented.

Water entry

  • Type of odor: Musty or damp odor that may be more noticeable after a rain storm. Long term exposure to moisture in the chimney can cause mold or mildew growth; in addition to creating a round-the-clock odor, mold growth can also affect the air supply in your home, especially for those with respiratory issues such as allergies or asthma.
  • Cause: While water can get into your chimney system in a number of ways, it most commonly comes in from a damaged chimney cap. In addition to protecting the chimney from moisture, chimney caps also keep debris and animals out of the chimney. Likewise, cracks or holes in the masonry can also cause water to enter the chimney system.
  • Signs of water entry: Using a flashlight, look in your firebox or the lower portion of the chimney for signs of moisture or water. Likewise, from the ground look for any evidence that the chimney is cracked or otherwise damaged.

Creosote

  • Type of odor: Sharp, smoky odor. Creosote smells are often worst during the hot and humid summer months.
  • Cause: Creosote is a naturally occurring byproduct of fuel-burning fires, but is most prevalent with wood burning fires. Tarry creosote can coat the inside of the chimney flue and leave you at increased risk for chimney fire. Annual chimney sweeping removes creosote – as well as the odors that can accompany it.
  • Other causes of smoky odors: Your smoky chimney odor may also indicate an air pressure problem; outside air flows down the chimney and into your home, bringing chimney odors with it. An improperly fitting damper or the installation of a new HVAC system can cause pressure imbalances.

  • Type of odor: Sharp, foul, rotting odor.
  • Cause: A sudden rotting smell almost always indicates the presence of an animal or animal droppings in the chimney. Animals can find their way in through a damaged or missing chimney cap or other surrounding masonry damage on the top of the chimney.
  • Getting animals out: Wild animals should ways be treated with caution and should only be removed by a professional. Likewise, it is important to never “smoke out” a trapped animal; rather than getting out of the chimney, many animals become disoriented or injured by the smoke and heat.

Stop dealing with foul odors coming from your fireplace. Contact Lords Chimney and let a certified professional inspect your chimney and start enjoying your heating appliance once more.

What causes chimney leaks?

Chimneys are built to stand strong against the elements; however, there are still a number of points where water can work its way into the chimney system. The following are some of the most common causes of chimney leaks.

Chimney cap: The chimney cap protects the top of the chimney and keeps moisture, animals, and debris from falling into the chimney. A damaged chimney cap can allow water into the flue, causing damage throughout the fireplace and chimney structure.

Chimney crown: Often confused with the chimney cap, the chimney crown is a mortar slab that seals the top of the chimney. Chimney crowns should have small overhangs as well as be built with slightly sloped edges to prevent water from pooling on the top. Chimney crowns can deteriorate over time due to prolonged exposure to the elements; this creates cracks that allow moisture into the chimney.

Flashing: Flashing is the watertight metal strips that seals the joint between the chimney and the roof. Over time, flashing can lose its seal due to overexposure to the elements; flashing can also be damaged by storms or animals.

Masonry damage: Without regular maintenance, bricks and mortar can begin to deteriorate over time. The freeze thaw process – which causes water in bricks to freeze and expand – is the most common cause of water damage to masonry.

Fixing a leaky chimney

When it comes to fixing a leaky chimney, the most important step is to find and repair the cause of the chimney leak. Repairing the water damage without first removing the cause of the chimney leak will only lead to recurrent water problems. By uncovering the root cause of the chimney leak, you can rest assured that the water damage will not return once the necessary repairs have been made.

For chimneys with damaged masonry, tuckpointing may be used to repair or replace damaged bricks and mortar. During the tuckpointing process, small areas of damaged masonry are carefully removed before the new bricks and mortar are put in; this can help strengthen the chimney structure and help avoid the costs of rebuilding the entire chimney.

Another great way to prevent chimney leaks and water damage is by having your chimney waterproofed. Professionally waterproofing a chimney can seal and protect the masonry from water damage while still allowing the bricks to retain their semi-porous nature.

Chimney sweeping logs are no replacement for a certified chimney sweep!

Every time you burn wood in your fireplace or wood stove, condensation forms on your chimney’s flue. That condensation forms a dark, tar-like, highly combustible substance called creosote. When creosote builds up in your chimney, it can lead to a damaging and dangerous chimney fire, or it can force carbon dioxide back into your home, endangering your family.

Creosote sweeping logs promise a solution. They claim to reduce creosote buildup in your chimney simply by burning them in your chimney. Some such logs carry the seal of approval of the Chimney Safety Institute of America (CSIA), but even the CSIA acknowledges that the logs are not a replacement for your annual chimney sweeping and inspection by a CSIA-certified chimney sweep.

Creosote sweeping logs don’t remove all creosote

Creosote sweeping logs work by sending chemicals up your chimney that react with the creosote, causing it to flake away and fall back down your chimney to your firebox, where it either burns up or can be swept away. At best, the logs only remove up to 60 percent of the creosote from you chimney over a 15-day period. That means that creosote still can build up to dangerous levels within your chimney, blocking smoke from leaving your chimney and potentially igniting a chimney fire.

Additionally, many fireplaces aren’t a straight vertical channel. That means creosote can fall to and gather on your chimney’s horizontal surfaces, where it can build up. If your chimney is a straight vertical line, the creosote that falls into the firebox can cause flare ups that can harm your hearth or someone standing near it.

Creosote sweeping logs can’t spot problems with your chimney

Your annual chimney sweeping is more than just a cleaning. Your certified chimney sweep also inspects your chimney for structural damage, water leaks, crumbling mortar, and other problems. A creosote sweeping log simply can’t help you identify and solve problems with your chimney. Missing your annual chimney inspection gives small problems, like a minor leak, time to grow into a major problem that potentially will be expensive to repair.

More importantly, your certified chimney sweep looks for problems that could lead to a chimney fire or carbon monoxide poisoning. That includes animals that have nested in your chimney or chimney fires that have gone undetected.

Schedule your annual chimney sweeping today!

While the CSIA recognizes that creosote sweeping logs can be a valuable piece of chimney maintenance, eliminating some creosote in between professional chimney sweepings, replacing your annual chimney sweeping and inspection with a creosote sweeping log is dangerous both for your home and your family. If you’re overdue for your annual chimney sweeping and inspection, call the CSIA-certified chimney sweeps at Lords Chimney. We’ll make sure that your chimney is creosote-free and ready to burn safely this winter.
