Removing creosote in Bloomington isn’t a DIY job, it takes the right tools to protect your brick and liners. A deep clean means brushing, vacuuming, and checking for cracks or rust, especially in older masonry chimneys. Skipping it turns your chimney into a fire risk, and Minnesota’s dry winters make that danger worse. Always hire a licensed sweep for safety and results.
What is creosote, and why does Bloomington’s climate turn it into a faster problem?
Creosote is the sticky, tar-like gunk left behind when wood burns. In Bloomington, where older brick homes with masonry chimneys are common, creosote builds up faster due to a few local factors: dry winter air, older wood stoves, and the way many homeowners burn damp or unseasoned firewood. The EPA’s Burn Wise program notes that incomplete combustion, often from burning green wood, accelerates creosote buildup, increasing fire risks. If your chimney hasn’t been swept in over a year, or if you’ve noticed a strong chemical smell when lighting your fireplace, creosote is likely the culprit. Creosote removal & deep cleaning Bloomington should be done at least once a year, but older homes may need more frequent cleanings due to wear in the brickwork.
Myth: ‘All chimney sweeps are the same’, what Bloomington homeowners assume (and why they’re wrong)
Not all chimney sweeps are equipped to handle the quirks of older Bloomington homes. For example, a sweep using a basic push broom might miss creosote in the joints of your brick chimney or fail to spot corrosion in a clay liner. In Bloomington, where many homes date back to the early 1900s, masonry chimneys often have cracks or deteriorated mortar that trap creosote deeper than surface-level cleaning can reach. A professional chimney sweep in Bloomington will use rotary brushes, high-powered vacuums, and inspection cameras to ensure every inch, including the liner and smoke chamber, is thoroughly cleaned. If your chimney has a liner, this step is critical: the Chimney Safety Institute of America (CSIA) warns that neglected liners can crack under creosote buildup, leading to dangerous chimney fires. For homes near the Mississippi River or in flood-prone areas like nearby Richfield, moisture damage can also weaken brickwork, making a deep clean even more essential.
A chimney inspection is a visual and physical check of your chimney’s structure, liner, and creosote levels, here’s what it includes
Before any cleaning begins, a proper inspection evaluates three key areas: the chimney’s physical condition, the type and stage of creosote buildup, and the integrity of the liner (if present). In Bloomington, where many homes have unlined masonry chimneys, inspectors look for spalling brick, cracked mortar, or rust in metal components. The NFPA’s chimney fire code (NFPA 211) requires Level 2 inspections before a chimney fire or major repair, but even unlined chimneys should be checked annually. During an inspection, your sweep will also assess the draft and smoke flow, poor draft can mean incomplete combustion, which worsens creosote buildup. If your home is in an older neighborhood like the one near the Mall of America, where brick homes are prevalent, expect to pay slightly more for a thorough inspection due to the extra time required for detailed masonry checks. Schedule a chimney inspection in Bloomington to avoid overlooking hidden risks.
Step 1: Removing loose creosote, why brushing alone isn’t enough in Bloomington’s dry climate
The first step in creosote removal is breaking up the buildup, but in Bloomington’s dry winters, creosote often hardens into a glass-like substance called ‘glaze.’ A basic brush won’t cut it, professionals use rotary brushes with stainless steel bristles to scrape away glaze without damaging brick or liner surfaces. For Stage 2 creosote (tar-like and sticky), a chimney sweep will apply a specialized solvent to soften it before brushing. In older homes, this process must be done carefully to avoid dislodging mortar or weakening the brick. After brushing, a powerful vacuum removes debris, but even then, some creosote can linger in crevices. That’s why a deep clean includes a final inspection with a camera to spot missed spots. If your chimney hasn’t been cleaned in years, expect to see more buildup, especially if you’ve been burning softwoods like pine, which produce more creosote. The U.S. Environmental Protection Agency recommends burning only seasoned hardwoods to reduce buildup, but even then, annual cleanings are a must in Bloomington’s climate.
Step 2: Deep cleaning the liner and joints, what most DIYers miss in Bloomington homes
Many homeowners stop at brushing the visible creosote, but the real risk lies in the liner and mortar joints. In Bloomington, where older homes often have clay or metal liners, creosote can seep into tiny cracks, accelerating corrosion. A professional sweep uses a flexible brush to reach around bends in the liner and a vacuum with a long hose to pull out debris from deep within. For masonry chimneys without liners, the sweep will also clean the joints between bricks, where creosote can pool and ignite. The Chimney Safety Institute of America (CSIA) emphasizes that neglected liners are a leading cause of chimney fires, particularly in older homes. If your liner shows signs of rust or cracking, it may need replacement, a job that requires a licensed chimney professional. During this step, your sweep will also check for animal nests or blockages, which are common in Bloomington’s older chimneys. Learn about chimney liner repair in Bloomington if your inspection reveals damage.
Step 3: Final inspection and safety checks, what to look for after cleaning
After cleaning, a thorough inspection ensures no creosote remains and that the chimney is safe to use. Your sweep will check for: residual buildup in the smoke chamber, cracks in the liner or brickwork, and proper draft flow. In Bloomington, where cold snaps can cause rapid temperature shifts, a weak draft is a red flag, it often means incomplete combustion, which leads to more creosote. If your chimney has a damper, the sweep will ensure it opens and closes smoothly. For homes near busy roads or industrial areas, soot from outside sources might also be present, requiring extra cleaning. The final step is a written report detailing any issues found, such as corrosion or structural weaknesses. If your chimney fails inspection, your sweep will recommend repairs before you light another fire. Review our chimney inspection process to understand what’s included in a professional cleaning.
What’s the real cost of clearing out creosote in a 1920s brick chimney on East Washington Avenue, and why do prices jump?

Frequently Asked Questions
Your chimney smells like chemicals when you light the fire. Is that creosote burning off?
Yes, that chemical smell is a sign of creosote burning off. It means your chimney has Stage 2 or Stage 3 buildup, which is highly flammable. In Bloomington’s dry winters, creosote ignites more easily, so if you smell this, schedule a chimney sweep immediately. Burning the fire hotter won’t fix it, only a professional cleaning with rotary brushes and vacuums can remove hardened creosote safely. Creosote removal & deep cleaning Bloomington should be done before winter to avoid fire risks.
Why does my older brick chimney in Bloomington need more frequent cleanings than newer homes?
Older brick chimneys in Bloomington lose their structural integrity over time, leading to cracks and gaps where creosote traps and accelerates. Without a liner, the brickwork absorbs moisture and soot, making buildup worse. The NFPA recommends annual inspections for unlined masonry chimneys, especially in areas with high humidity or frequent temperature swings like near the Mississippi River. If your home is over 50 years old, consider a chimney liner to protect the brickwork and reduce cleaning needs.
Can you light your fireplace in Bloomington right after a sweep, or should you wait?
You can use your fireplace immediately after a cleaning, but wait at least 24 hours to let any residual dust settle. If your sweep used solvents to break down creosote, avoid burning a fire for 12–24 hours to allow fumes to clear. In Bloomington’s cold winters, many homeowners light a small fire right after cleaning to test the draft and ensure no debris remains. However, if your chimney had heavy buildup or repairs, follow your sweep’s advice, some recommend waiting longer or burning only small, dry fires until the next inspection.
My neighbor in Brooklyn Park swears by their DIY chimney cleaning, why should I hire a professional in Bloomington?
DIY cleaning is risky, especially in Bloomington’s older brick homes. Without the right tools, you can damage liners, dislodge mortar, or miss creosote in hard-to-reach spots. The CSIA reports that improper cleaning is a leading cause of chimney fires. Professionals use rotary brushes, vacuums, and cameras to ensure a deep clean, while DIY methods often leave residue. Plus, a licensed sweep will spot structural issues, like cracks in your brick chimney, that a homeowner might miss. Find a licensed chimney sweep in Bloomington for safety and peace of mind.
