Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Sweep Across Chicago Loop
Chimney sweep service in Chicago Loop means working on rooftop boiler flues, restaurant grease ducts, and mechanical exhaust stacks on towers – not residential fireplaces. A typical Level 1 inspection of a boiler flue or a grease-duct cleaning in the Loop runs between $250 and $600 depending on flue height, access, and buildup. We know the building-management access rules, the freight-elevator windows, and the night-work requirements downtown, and we schedule around them. Call (833) 589-7835 for a free estimate on any Loop flue or exhaust stack.
Why Sandstone Chimney Sweep Is Chicago Loop’s Preferred Chimney Sweep Company
Sandstone Chimney Sweep is led by Norm Sobieski, who has built our reputation on one principle: the team that inspects is the same team that repairs. In the Loop, that continuity matters more than anywhere else in the city. When a ground-floor restaurant’s grease duct shares a vertical chase with a second-floor office exhaust, the sweep who finds the cross-contamination is the same crew that seals it. No handoff to a subcontractor. No lost diagnosis between invoice pages.
We work with the product lines Chicago’s commercial and institutional buildings actually require: Copperfield for damper components, HeatShield for flue resurfacing, DuraFlex for liner systems. Property managers and building engineers in the Loop recognize these names because they’re specified by certified chimney professionals, not whatever ships cheapest from a big-box distributor.
Our Chimney Sweep team knows the Loop’s rooftops, the alley access points, and the landmarks. We’ve climbed more Wabash Avenue ladders and navigated more freight elevators off State Street than we can count. That familiarity is the difference between a four-hour access delay and a two-hour job done right.
Customers in Chicago Loop call us because we explain what we found – with camera evidence – before we recommend anything. Nothing gets prescribed without footage you can see. That honest diagnosis is why building engineers keep our number on file.

Fireplace Cleaning in Chicago Loop
Fireplace Cleaning in Chicago Loop is a specialist job, not a residential sweep. The Loop’s building stock is overwhelmingly tall steel-and-concrete commercial towers, historic early-20th-century masonry high-rises, and dense restaurant/retail at street level. So when we clean fireplaces here, they’re usually in landmark-protected masonry buildings – think the vintage high-rises along Michigan Avenue or the historic loft conversions near Printers Row. These buildings have ornate fireboxes, clay tile flues, and chimneys that have survived a century of lakefront weather.
A fireplace cleaning in these Loop buildings typically runs $180 to $300. The work involves removing soot and creosote from the firebox and smoke chamber, cleaning the flue, and checking damper function. Because so many Loop buildings are landmark-protected, we’re careful about historical fabric – we don’t use aggressive rotary methods where they could damage original tile liners.
Creosote and Soot Removal in Older Masonry Flues
Older Loop fireplaces often have decades of layered buildup. We remove first-degree soot with standard brushes, but second-degree creosote – the flaky, tar-like accumulation – needs rotary loops or chemical treatment. In shared chimney stacks, this work is trickier: we have to isolate the flue we’re working on so we don’t push debris into a neighbor’s liner.
Annual Sweep for Code-Required Maintenance
Many Loop buildings with fireplaces in lobby spaces or amenity floors require annual sweeping as part of their insurance or landmark compliance. We document everything with photos and a written report, so the building file has a maintenance record. That documentation matters when the city or the insurer asks.
Chimney Services in Chicago Loop
Chimney Services in Chicago Loop center on commercial and institutional flues: boiler exhaust stacks, restaurant kitchen exhausts, and mechanical-draft venting. A Level 2 inspection here typically runs $300 to $650, depending on roof access and the number of flues. You need this inspection whenever there’s been a change to the venting system, a reported odor complaint, or a suspected back-draft between tenants. In stacked Loop buildings, these are not optional.
Level 2 Inspection of Shared Flues and Vertical Chases
In a Loop high-rise, multiple tenants can share a single brick chimney stack. Our Level 2 inspection uses a video camera to trace each flue from the appliance to the roof termination. We’re checking that every flue is properly separated, that no cracked mortar is allowing cross-leakage, and that the cap and crown are intact. This inspection is what tells us whether a neighbor’s exhaust is entering your space.

Damper Replacement and Smoke Chamber Sealing
When a shared flue’s damper seal fails, the smoke chamber becomes a highway for vapors. We replace worn dampers with Copperfield models – the same line specified on commercial flue drawings – and seal smoke chambers with HeatShield to stop cross-contamination. This is repair work, not patching. It’s built to outlast the season.

Trusted Brands We Service in Chicago Loop
When we repair or resurface a flue in the Loop, we use the same product lines building engineers and certified chimney contractors specify: DuraFlex liner systems, HeatShield resurfacing, and Copperfield dampers and caps. These are specification-grade materials, engineered for chimneys, not consumer-grade substitutes. For Chicago Loop customers, that means we can pull parts from stock that match the original system – no waiting on a special order, no mixing brands. If the flue needs work, we find it and we fix it, with materials a building inspector will recognize. Your flue is a system, not just a pipe.
Common Chimney Sweep Problems We See in Chicago Loop Homes
- Shared flue cross-contamination. In dense Loop towers, a neighbor’s boiler or grease duct can leak creosote vapors and carbon monoxide into your space through a shared stack. A Level 2 inspection here must verify that every flue is properly separated, something a detached single-family home never faces.
- Third-degree creosote glaze in restaurant exhaust stacks. Grease-laden exhaust plus Chicago’s summer heat and humidity creates a hard, shiny glaze that a standard brush won’t touch. Only chemical treatment removes it safely, and skipping it risks a grease fire.
- Cracked chimney crowns on landmark masonry high-rises. Chicago’s freeze-thaw cycles are brutal on brick. When roof access is tight and building management limits work hours, crown cracks and spalling go undiscovered for years – until water gets into the flue.
- Winter draft problems from flue condensation. Lakefront cold causes flue gases to condense inside the liner, which corrodes metal and degrades mortar. In Loop boiler stacks, that condensation plus bitter cold creates draft problems that send carbon monoxide back into occupied floors.

FAQs About Chimney Sweep in Chicago Loop
We run a video camera up each flue from the appliance to the roof termination, checking that every liner is intact and properly separated at every joint. In shared stacks, we’re specifically looking for cracked mortar, failed damper seals, or any point where one tenant’s exhaust can cross into another’s space.
This is what catches the situation we see on Wabash Avenue: a ground-floor restaurant reported grease odors in a second-floor office, and our Level 2 inspection found first-degree creosote and a failed damper seal in the adjacent firebox flue. We replaced the damper with a Copperfield model and sealed the smoke chamber with HeatShield. Call (833) 589-7835 to schedule an inspection of your shared flue.
Chicago’s summer heat and humidity increase grease-vapor buildup in restaurant exhaust ducts, creating a thicker, stickier accumulation than cooler months produce. That buildup plus a hot kitchen is the classic recipe for a grease fire.
In the Loop specifically, this is worse because vertical grease ducts run up through occupied floors, so you’re not just protecting the kitchen – you’re protecting every office, apartment, and tenant above you. Tight scheduling around building access usually means booking two to three weeks ahead in summer. Call (833) 589-7835 to get on the calendar.
Yes. We work on landmark-protected masonry high-rises throughout the Loop regularly, including on Michigan Avenue, Wabash Avenue, and near Printers Row. We use cleaning methods appropriate to the age and condition of the flue – standard brushes for soot, rotary loops for creosote, and chemical treatment for hardened glaze.
Landmark buildings often have clay tile liners that can crack under aggressive mechanical cleaning. We always match the method to the liner material. We also document the before-and-after with camera footage, which helps with landmark compliance and insurance records. Call (833) 589-7835 for an assessment.
Chicago’s lakefront winters create two problems: cold air dense enough to push back down the flue, and flue-gas condensation that corrodes liners and degrades mortar joints. On tall Loop towers, the stack effect adds another layer – the building itself pulls air through the flue at a rate no single-family home experiences.
We diagnose draft problems by measuring pressure at the appliance, checking flue diameter against the appliance’s BTU output, and inspecting the liner for condensation damage. Often it’s a sizing issue or a failed cap, not a blockage. Call (833) 589-7835 if you’re noticing downdrafts or exhaust odors on the upper floors.
Third-degree creosote is a hard, shiny glaze that a standard wire brush won’t remove. We use chemical treatment – a solvent that breaks down the glaze – followed by rotary cleaning to remove it fully. In Loop restaurant stacks, this is a code compliance issue, not just a maintenance preference.
Because Loop grease ducts run through occupied spaces, we schedule the work when the kitchen can be down and the building can give us roof access – often off-hours or overnight. The goal is no residue left that could ignite. Norm Sobieski, our owner, has built our reputation on not cutting this corner. Call (833) 589-7835 to schedule a chemical treatment.
