Markham sits just southwest of Chicago’s city limits, a grid of modest post-war ranches and Cape Cods along Pulaski Road and 159th Street. These homes were built fast during the 1950s and 1960s suburban boom, and their chimneys have been baking, freezing, and thawing for sixty to seventy years. That history matters when you’re choosing who to let into your house with a brush and a camera. We’ve been serving local communities for over 42 years, and we plan to be here in thirty more. We act accordingly.

We know Markham’s specific chimney problems because we’ve solved them hundreds of times. The oversized coal-era flues. The cracked clay tiles from decades of freeze-thaw.

Our Chimney Cleaning & Sweep Services in Markham

Level 1 Inspection

A Level 1 inspection is the baseline annual check for Markham chimneys that have not changed service or experienced any known problems. We examine the readily accessible portions of your chimney exterior, interior, and appliance connection. For most Markham ranch homes with original masonry, this means checking the firebox, damper, smoke chamber, and accessible flue for obstructions and basic soundness. If your chimney has been swept regularly and you’ve made no changes, this may be sufficient. We charge $89 for our Seasonal Tune-Up, which includes this inspection.

Level 2 Inspection

Level 2 inspection is what most Markham chimneys actually need. We use a specialized camera to examine the full length of your flue, documenting every crack, gap, and creosote deposit. This is essential for any home built before 1970, and Markham is almost entirely built before 1970. On a recent job on 163rd Street, our crew found a 1950s ranch where the original clay-tile liner had cracked from freeze-thaw cycles, and the oversized flue, meant for a coal furnace, was causing condensation that glued creosote to the smoke chamber walls. We used HeatShield to patch the cracked tile and installed a DuraFlex liner to resize the flue, then cleaned 3 gallons of low-lying creosote. Without the camera, that damage stays hidden until it’s dangerous. Level 2 inspections in Markham run $225 to $340 depending on accessibility and documentation needs.

Creosote Removal

Here’s what makes Markham different from newer suburbs: in Markham, over 70% of chimney sweeps involve homes where the original coal-era oversized flue was never resized after conversion to natural gas, so creosote deposits accumulate as low as 12 inches above the smoke shelf, far below the usual cleaning zone. A standard sweep from a technician who doesn’t know this will miss it. Our crews are trained to find and remove this low-lying buildup. We use professional-grade brushes, rods, and vacuums, and we verify our work with the camera before we leave. Creosote removal in Markham typically runs $150 to $275 for a standard sweep, or $275 to $425 when combined with Level 2 inspection and documentation.

Soot Removal

Coal soot and modern wood-burning soot are different materials, and Markham chimneys often contain both. The old coal soot is denser, more acidic, and harder to remove. It also indicates whether your chimney has been properly maintained through decades of fuel changes. We evaluate what we’re removing and advise accordingly. Soot removal alone runs $125 to $200; when combined with creosote removal and inspection, we bundle for efficiency.

Annual Sweep

For Markham homeowners who use their fireplace regularly, an annual sweep is the standard of care. Given our local freeze-thaw cycles and the age of these chimneys, we recommend annual service even for occasional use. The condensation from oversized flues creates acidic liquid that eats through clay-tile mortar joints. Catching this early prevents the hidden smoke leaks that make these old chimneys dangerous. Our $89 Seasonal Tune-Up makes this routine and affordable.

Fireplace Cleaning

Fireplace cleaning addresses the firebox, damper, smoke shelf, and visible flue entrance. In Markham’s shallow ranch fireboxes, smoke shelf design was often minimal, making proper draft dependent on a clean, correctly sized flue. We clean what you can see and inspect what you can’t.

Trusted Brands We Service in Markham

We work exclusively with professional-grade materials. For liner replacements and flue resizing in Markham’s older chimneys, we use DuraFlex stainless steel liners and HeatShield cerfractory flue sealant. These are not builder-grade substitutes. We stock components locally so Markham jobs don’t wait on shipping. When we find damage during your sweep, we can often repair it same-day rather than scheduling a return visit. That’s the difference between a sweeper with a brush and a company that plans to stand behind the work for decades.

Common Chimney Cleaning & Sweep Problems We See in Markham Homes

• Low creosote deposits from oversized flues. The reduced heat output of a modern fireplace venting through a coal-era flue leaves gases sitting long enough to condense and deposit creosote unusually low. Most homeowners never know it’s there. We find it with the camera, and we remove it completely.
• Cracked flue tiles from freeze-thaw damage. Markham sits in the Chicago metropolitan freeze-thaw zone, where temperatures cycle above and below 32°F dozens of times each winter. Water enters mortar joints and tile cracks, expands with each cycle, and gradually destroys the liner. Cracked tiles allow creosote to seep behind the liner, creating a fire risk no standard sweep can remove.
• Chimney crown and cap failure from northwest wind exposure. Markham’s south suburban location means chimneys face prevailing northwest winds off the open prairie. Improper or missing chimney caps let wind-driven rain erode the crown, causing persistent water damage and spalling brick. A sweep alone cannot fix this, but we’ll document it and show you exactly what needs attention.
• Condensation damage from conversion-era flue sizing. When a coal or oil furnace flue is left oversized for a modern gas fireplace, the reduced heat output creates chronic condensation. This acidic liquid dissolves mortar joints from the inside, leading to hidden smoke leaks into adjoining walls. We find this damage during Level 2 inspection and can resize the flue with a DuraFlex liner to stop the cycle.
