Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
HeatShield Chimney Cleaning in Chicago Loop, IL | Wexford Chimney Sweep
We provide independent HeatShield repair in Chicago, including chimney cleaning and resurfacing service across the Loop, from the LaSalle Street canyon to the tower stacks along Michigan Avenue. What makes our HeatShield work different here is simple: we know how the product cures inside interior mechanical shafts where freeze-thaw cycles and shared flues are the rule, not the exception. If you manage a Loop building with a HeatShield-lined flue that needs cleaning, inspection, or repair, call us at (866) 361-2607 for a free estimate.
We’ve applied and serviced HeatShield’s ceramic silicate resurfacing system in downtown Chicago towers for years, and we’re trained in the full application process. We’re an independent chimney sweep, which means we’re not authorized by, partnered with, or endorsed by HeatShield. We work with the product because it performs in the right conditions, and we’ll tell you plainly when it won’t.
Why Chicago Loop Residents Choose Us for HeatShield Service
Most chimney companies in Chicago never touch a HeatShield service in West Town or elsewhere. We work with it regularly, and we stock the ceramic silicate sealant and compatible stainless components so a Loop building isn’t waiting on a parts shipment from out of state. Norm Sulecki, our owner, grew up near the Hawthorne Race Course in Cicero and has been working on chimneys across Cook County for nearly two decades. He started Wexford because he got tired of seeing homeowners and building managers handed recommendations they had no way to verify. We show you what we see, with a camera when it matters, and we don’t recommend resurfacing work that won’t hold.
Chicago Loop buildings rarely have a single-family fireplace to sweep. What they have are shared boiler flues, commercial kitchen exhaust runs, and historic terra-cotta stacks that run through interior light wells. That’s exactly the kind of work we do. Whether you need a Level 2 inspection, creosote removal, or crown coating on a HeatShield-lined flue, we’re already familiar with how your building is put together.

Common HeatShield Chimney Cleaning Problems We Solve in Chicago Loop
- Flaking and delamination where lake moisture gets behind the coating. Unlined brick stacks in the Loop take a beating from Lake Michigan moisture and freeze-thaw cycles. When water seeps into the masonry and freezes, it expands and can push a HeatShield coating away from the flue wall. We see flaking most often in pre-war towers near the river where humidity is constant. The fix starts with finding the water entry point, not just recoating.
- Fresh HeatShield material cracking before the cure window closes. HeatShield needs a full 48-hour cure before a flue sees heat. In Loop restaurants and hotels, a kitchen exhaust or boiler flue sometimes gets fired early because operations can’t pause. The coating cracks, and you’re back to square one. We coordinate cure windows with building engineers so the liner gets the time it needs.
- Adhesion failure over soot-contaminated masonry. HeatShield won’t bond to creosote or heavy soot. In Loop towers with shared heating flues, decades of buildup can coat the original clay tile. If the flue wasn’t properly wire-brushed before application, the liner delaminates in sheets. We clean to bare masonry before any resurfacing work happens.
- Liners pulling away from shifting terra-cotta terraces. Late-19th-century Loop buildings have orig inal clay tile flues that spall and shift over time. HeatShield applied over a flue that’s actively moving will detach. We inspect for structural movement before recommending any coating work.
- Debris dropping into tenant spaces between heating seasons. Freeze-thaw spalling sends mortar and clay tile fragments down shared shafts. If a HeatShield liner wasn’t crown-coated at the top, water keeps getting in and the cycle continues. We treat the crown and the flue together, not one or the other.
HeatShield Service in Chicago Loop: What Local Conditions Mean for Your Equipment
Most Chicago Loop chimney stacks sit inside interior mechanical shafts and light wells with no exterior ladder access. We routinely coordinate with building engineers to book freight-elevator time and haul gear to a rooftop penthouse before a single brush goes down a flue. That’s not how most chimney companies operate, and it’s why a generic HeatShield service call in the Loop often fails before it starts. If your flue is behind locked mechanical doors on the 40th floor, we need engineer access, elevator reservations, and sometimes a rooftop hatch key. We handle that logistics chain ourselves so the building manager doesn’t have to.
This access issue shapes the work itself. Because travel to the roof is slow and scheduled, we carry full inspection cameras and multiple brush sizes on the first trip. We don’t do a quick look and schedule a second visit. When we’re on your roof, we’re there to sweep, inspect, and tell you what’s actually going on inside the flue.
HeatShield Models & Products We Service in Chicago Loop
We service the full HeatShield product line used in Chicago Loop buildings. The HeatShield Cerfractory Flue Sealant is the pourable ceramic silicate liner resurfacing product we apply to unlined or deteriorating masonry flues. The HeatShield-PC positive-connection application works for smaller flues where a full pour isn’t practical. We also fabricate and install HeatShield custom stainless chimney caps and multi-flue cap systems sized to fit historic Loop stacks, which rarely match modern off-the-shelf dimensions.
We use HeatShield’s own sealant and compatible stainless hardware, never a substitute product. The coating chemistry bonds correctly only when the materials match. That said, we won’t apply HeatShield over a flue that’s structurally failing. A spalled crown or crumbling clay tile needs repair or rebuild first, or the coating will detach regardless of what we do. Our job is to tell you which situation you have.

AfterHeatShield Service Pricing in Chicago Loop
HeatShield service pricing in Chicago Loop depends on flue access, liner condition, and building logistics. A standard cleaning and inspection for an accessible residential flue in the Loop typically runs $220 to $380. A Level 2 camera inspection adds $150 to $300. Full HeatShield resurfacing in a high-rise commercial flue is a different job entirely, ranging from $3,000 to $9,000 depending on flue height, access difficulty, and surface preparation required. Crown coating work adds $600 to $1,800 for a typical Loop stack.
These are honest ranges, not bait numbers. The freight-elevator coordination, engineer scheduling, and rooftop logistics in a Loop tower add real time and cost that suburban pricing never accounts for. Call (866) 361-2607 and we’ll walk the flue with you before quoting anything. Estimates are free, and we don’t recommend a dollar of work you don’t need.

FAQs – HeatShield Chimney Cleaning in Chicago Loop
Yes. Most Loop stacks are reached through interior mechanical shafts, roof hatches, or penthouse access, and we handle all of that coordination ourselves. We book freight-elevator time with your building engineer, arrange access to locked mechanical rooms, and haul our equipment to the roof before any work starts. If your building has a designated engineer contact, we work through them directly.
It does when the flue is structurally sound and the crown is sealed. HeatShield’s ceramic silicate coating holds up to repeated freeze-thaw cycles in the Loop, but only if water isn’t getting behind it. A cracked crown or shifting terra-cotta will defeat any liner system. That’s why we inspect the crown and flue as a unit before recommending resurfacing. Call (866) 361-2607 for a free estimate and we’ll show you what’s happening up there.
A HeatShield liner can be cleaned on a commercial schedule, but we need to coordinate firing pauses around the work. The flue has to cool before we can safely sweep and inspect it, and any repair or recoat work requires a 48-hour cure window before the kitchen fires again. We’ll work with your kitchen manager to schedule us during a slow period or overnight shutdown if your building allows it. Call (866) 361-2607 and we’ll build a schedule that matches your fire-code requirements.
A Level 1 inspection is a visual check of the accessible portions of the flue, the firebox or exhaust connection, and the cap. A Level 2 adds a camera scan of the full flue interior, which matters in Loop towers where a shared boiler flue may run 20 to 40 stories through interior shafts you can’t see into from the roof. If debris has been dropping into tenant spaces or the liner was installed years ago, a Level 2 is what actually tells you the condition. We include camera inspection as a standard part of our HeatShield work in Chicago Loop.
Freeze-thaw spalling in the Loop’s brick and terra-cotta stacks loosens mortar and clay tile fragments, which then drop down the flue and into tenant spaces. If your flue has a HeatShield liner that’s pulling away from the walls, the debris is coming from behind the coating. Our East Garfield Park HeatShield service follows the same inspection protocol. The fix starts with a camera inspection to find the source, then crown coating or spot resurfacing to seal the entry points. Call (866) 361-2607 for a free estimate and we’ll pinpoint exactly where the debris is coming from.
