Chimney Cleaning – Why You Should Hire a CSIA-Certified Chimney Sweep

A dirty chimney is a fire hazard that professionals should only clean and inspect. Hire Clean Chimney Sweep Charleston and ensure the fireplace is ready to be used again before the heating season begins in the fall. Before sweeping, tape plastic across the fireplace opening and close the damper. Also, prepare a ladder and cleaning tools like chimney brushes (long rods with bristles) and extension poles.

When wood is burned, it releases both energy and unwanted byproducts. One of the most dangerous is creosote, a dark, tar-like substance that accumulates in chimneys over time due to incomplete combustion. When too much creosote builds up inside a chimney, it can cause serious issues that threaten the home’s and its inhabitants’ safety.

Chimneys can experience three stages of creosote buildup, which are degrees or levels. Stage 1 creosote is loose and flaky, allowing it to easily be removed by a chimney sweep with a brush or cleaning log. It is important to remove this creosote regularly to prevent it from progressing to stage two, which looks like black tar and is more difficult to remove than the previous stage.

Insufficient airflow and a fire that burns too fast can lead to incomplete combustion, which causes a buildup of loose and flaky creosote in the flue. This type of creosote is called first-degree buildup and can be easily removed by a professional chimney sweep with a brush or cleaning tool.

If not removed regularly, first-degree creosote can deteriorate to second-degree creosote, which is more solid than the loose flakes of stage 1. This thicker deposit may look like black tar and be harder to remove. It can also pose a more significant risk for chimney fires, so it is critical to address any signs of this type of creosote buildup as soon as possible.

If left unaddressed, second-degree creosote can further deteriorate to third-degree creosote. It is a hard, shiny, and tar-like deposit that is nearly impossible to remove. It can block a chimney completely, causing smoke and toxic gases to escape into the house. It can also damage a chimney lining and lead to a chimney fire.

It is important to note that while some chimney companies try to use scare tactics by demonstrating how much creosote has built up inside a chimney, this needs to be more accurate and could indicate a scam. If a chimney sweep uses terms like carbon monoxide poisoning or house fire to frighten you, get a second opinion or call another company.

Chimney fires are often caused by a buildup of creosote, a flammable residue that collects on the walls of a chimney flue liner and restricts airflow. It’s a dangerous byproduct of wood burning and is highly volatile, even when dampened. It can also cause cracks in the “fireproof” brick, stone, or clay chimney lining, allowing hot gases to reach combustible materials inside your home, such as wood framing, curtains, rugs, clothing, furniture, and other living areas.

During a chimney cleaning, a professional will use a tool that looks like a giant bottle brush with metal bristles on the top to scrape away the layer of creosote and other debris from the chimney lining. They will typically put down a drop cloth to protect floors and furnishings, a HEPA-rated vacuum for dust control, and masks for their protection. They start at the bottom of the chimney and work their way up, or they may begin on the roof and work their way down to ensure that all the accumulated creosote and other debris is scraped off the chimney.

While the chimney sweep works on your fireplace and chimney, they will carefully inspect it for any other potential hazards. They will look for any obstructions, such as animal nests, twigs, and branches that may have blown into the chimney from outside, and check for damaged or missing flue liners. Chimneys without chimney caps and poorly designed or placed caps are especially susceptible to windblown debris that can enter the flue and block the airflow.

Having your chimney cleaned before the colder weather and heating season arrives is one of the most important things you can do to protect your family, pets, and belongings. It’s a good idea to contact a CSIA-certified chimney sweep and schedule an appointment in the late spring or summer while the weather is still warm. This way, your chimney will be ready to use once the temperature drops in fall and winter.

Chimneys provide a complex system through which fire byproducts like smoke and carbon monoxide can safely exit the home. However, if the vent becomes clogged or damaged, it can prevent these harmful byproducts from going, leading to health hazards and even house fires. Regular maintenance and inspections can help keep the chimney functioning properly, but professional cleanings are often needed to remove creosote and other debris.

A dirty chimney can also reduce energy efficiency. The combustible byproducts of burning wood are vented through the chimney flue, but a buildup of soot and other debris can prevent them from exiting efficiently. As a result, the chimney may have to work harder to vent smoke and heat, which can lead to higher utility bills.

A professional chimney sweeper will survey and prepare the area before beginning the cleaning process. They will put down-drop cloths or plastic to protect your carpet and furnishings and use a high-powered HEPA-rated vacuum for dust control. They will also wear goggles and masks to ensure they don’t inhale any toxins created by the creosote. Depending on the size of your chimney and its condition, they may start their work from the flue, the roof, or both.

Once the chimney is clean, the sweep will inspect it again to determine whether any repairs are required. It is also important to hire a qualified professional, as working on the roof can be dangerous. A reputable sweep will be able to spot problems like cracks or leaks and repair them before they become serious issues.

In addition, a skilled chimney sweep can often spot problems outside your fireplace or chimney, but could still be costly. For example, if the damper is not sealing properly, cold air can rush into your home, increasing heating costs. A chimney sweep will be able to fill this gap to help improve your energy efficiency and save you money.

Chimney sweeps and other professionals use various tools to clean chimney flues. They also carry general liability and workers’ compensation insurance to protect themselves and their customers from unforeseen accidents. It is good to check their certification on the CSIA website and ask for references.

Protective eye protection and a dust mask or respirator are important regardless of how you clean your chimney. A stray piece of creosote or a rogue chimney fire can cause serious injury. It would be best to only climb on the roof with a sturdy ladder and proper safety equipment. A fall from a rooftop can paralyze or kill you.

If you plan to perform a chimney cleaning yourself, purchase a pulley rope system for the brush. The system consists of two ropes attached to the meeting, one on top and the other on the bottom. A person on the roof should hold one end of the rope while someone inside the fireplace lowers the other and pulls it up and down the chimney. This system allows one to clean the entire flue while standing on a ladder safely.

Ashes should be removed from the fireplace regularly to help prevent a creosote buildup and reduce the likelihood of a chimney fire. Removing them when cool is a good idea, as hot ashes can crack the chimney flue. Adding ashes to garden beds or soil improves moisture and helps the plants grow.

A chimney fire is a disaster that can destroy your home. It begins with snaps and pops that sound like gunshots, then progresses to a roaring fire. As the fire rages, it can melt through the flue and pour oily, flaming creosote into the fireplace and living rooms. The fire can also cause chimney and house damage from the resulting water flood.

The best way to avoid chimney fire is with regular maintenance by a professional. An examination and cleaning by a certified chimney sweep will ensure that your chimney and flue are safe for fires and smoke.
