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 Belmont Cragin, IL | Brightway Chimney Sweep
We provide independent Belmont Cragin Chimney Sweep and HeatShield repair across this neighborhood, specializing in the unlined 1920s – 1940s brick chimneys this neighborhood was built with. What makes our HeatShield work different here is simple: on the two-flats along Diversey and Fullerton, a “routine cleaning” almost always turns into a liner-verification job, because the furnace and water heater often share one flue with an orphaned fireplace. We’re not authorized or endorsed by HeatShield – we’re a local trade contractor who recommends it only when the flue condition genuinely calls for it. Call (833) 365-6591 for a straight answer about your chimney.
Why Belmont Cragin Residents Choose Us for HeatShield Service
HeatShield isn’t a product most sweep companies here work with. It requires training, specific mixing ratios, and an understanding of how the Cerfractory material bonds to old Chicago common brick. Our owner, Neil Borowski, grew up a few blocks from Eckhart Park in West Town and has spent the better part of three decades working on the same kind of two-flats and greystones that fill Belmont Cragin. When we evaluate a HeatShield chimney cleaning or resurfacing job, we’re looking at it through the lens of someone who knows what these chimneys looked like when they were first built. For us, HeatShield sales & service means the actual work: Level 2 inspections, creosote removal, crown repair, and Cerfractory resurfacing done to spec, not a product push.
Homeowners here tend to be careful spenders. They want to know whether a 90-year-old chimney can be saved or if it’s time for a rebuild. That’s the conversation we’re comfortable having. We use genuine HeatShield materials when we do liner or crown work and we match them with quality aftermarket stainless caps, dampers, and flashing when the original parts are still sound. No generic substitutes, no upselling.

Common HeatShield Chimney Cleaning Problems We Solve in Belmont Cragin
We see the same handful of failure patterns repeating across Belmont Cragin’s housing stock. Most trace back to one thing: these chimneys were built without clay tile liners, and Chicago’s weather hasn’t been kind to them since.
- Cerfractory delamination after freeze-thaw cycles. When a chimney crown was never sealed properly, water gets behind the HeatShield liner, freezes, and separates it from the brick. We see this on bungalows where the original crown was poured flat, and meltwater ponds there all winter.
- Spalled and separated clay tiles after resurfacing. On chimneys that had a partial tile liner installed decades ago, soot or moisture can compromise the HeatShield bond. The tile face starts chipping away, and you’ll find tile fragments in the cleanout.
- Crown coating failure on original 1920s – 1940s crowns. Belmont Cragin’s older brick crowns were rarely sloped correctly. Water sits, refreezes, and pops the HeatShield coating within a few seasons. The coating isn’t the problem; the underlying slope is.
- Overheated firebox repair from gas inserts. When a gas log set or insert was added without resizing the flue, the extra heat degrades the firebox mortar and any HeatShield repair beneath it. We usually find this on greystones where a fireplace was converted to gas in the 1980s or 1990s.
- Back-drafting from shared flues. On two-flats, the furnace and water heater sharing a flue with a fireplace creates negative pressure. The exhaust doesn’t vent, it circulates back through the home. HeatShield resurfacing alone won’t fix this – the flue needs to be sized and often relined with a proper system.
HeatShield Service in Belmont Cragin: What Local Conditions Mean for Your Equipment
Here’s the thing a generic HeatShield page won’t tell you about Belmont Cragin. The neighborhood’s two-flats along Diversey and Fullerton were almost all built with a single flue serving multiple appliances. Back when these buildings went up, that flue handled one coal furnace and maybe a fireplace. Today it’s handling a modern gas furnace, a water heater, and in some cases a fireplace that hasn’t been used in twenty years. The flue was never sized for that load. So when we get a call for a “routine cleaning” in Belmont Cragin service area, our tech is checking for back-drafting before anything else. We’ve had calls where the homeowner wanted a simple sweep, and the real issue was exhaust gases pulling back into the second-floor unit. That’s not something a brush fixes. It means a liner-verification, often a HeatShield resurfacing or a stainless reline, and a conversation about what that flue actually needs to carry. The dense lot spacing and gangway access here also mean our techs are carrying equipment through narrow side passages and working off flat rear roofs. We plan for that.
HeatShield Models & Products We Service in Belmont Cragin
We install and service HeatShield in Irving Park and throughout Belmont Cragin: the Cerfractory Flue Sealant for cast-in-place liners, the Resurfacing System for cracked or spalled clay tiles, the Crown Repair and Crown Coating products, and the HeatShield multipurpose refractory mortar for firebox and damper face work. When we do a liner job, we use genuine HeatShield Cerfractory because the formulation carries the rating – aftermarket equivalents don’t perform the same way under repeated freeze-thaw. For parts like stainless caps, dampers, and flashing, we source quality aftermarket pieces from professional chimney supply lines like Olympia Chimney and Famco. That means we’re not waiting on a manufacturer shipment for a basic cap. We stock what Belmont Cragin chimneys need so most jobs can move forward quickly.

AfterHeatShield Service Pricing in Belmont Cragin
A HeatShield chimney cleaning in Belmont Cragin typically runs $185 – $300 for a standard sweep with a basic inspection. A Level 2 inspection with camera work lands between $295 and $495, depending on the roof access and whether we’re working from a gangway ladder or a flat roof. If the flue needs ceramic resurfacing or crown repair, that’s a separate scope we quote after the inspection; we don’t throw out numbers for repair work before we’ve seen the flue condition. The factors that move your price: roof access difficulty, flue height, degree of creosote buildup, and whether the crown has existing damage. Every quote covers the materials and the labor, and you’ll see it all before we start. Call (833) 365-6591 for a free estimate on your Belmont Cragin chimney.

FAQs – HeatShield Chimney Cleaning in Belmont Cragin
HeatShield Cerfractory is often the right fix for an unlined 1920s bungalow chimney if the brick is structurally sound and the flue shape is regular. It seals the masonry and gives you a smooth, rated liner without the cost of demolition. But if the brick is spalled, the chimney is leaning, or the flue has multiple offsets that can’t be properly coated, a stainless DuraFlex liner is the better call. The only way to know is with a camera inspection. We do that on every HeatShield evaluation. Call (833) 365-6591 to schedule one.
Back-drafting happens when the flue is oversized, undersized, or pulling air from multiple appliances that weren’t designed to share it. Your two-flat was likely built with one flue for one coal furnace. Now it’s carrying a gas furnace and a water heater, and the fireplace opening is pulling air back down when those appliances run. The fix usually involves sizing the flue and relining it – HeatShield may work, or a stainless liner may be required. We’ll tell you after a Level 2 inspection, not before. Call (833) 365-6591.
Freeze-thaw is the main reason HeatShield crown coatings fail here. If the crown wasn’t sloped to shed water, meltwater pools, refreezes, and pops the coating. That’s why we don’t just coat over a flat crown. We check the slope, repair the wash if needed, and then apply the HeatShield product. A properly sloped crown with a good coating lasts for years in this climate. A coating over a bad slope is a short-term patch. Call (833) 365-6591 if you want us to look at yours.
Yes, but only if the flue is sized correctly for the insert’s BTU output. A gas insert in a 1920s greystone chimney that was originally built for wood generates different exhaust temperatures and volumes. If the flue is too large, the exhaust cools and condenses, which degrades the HeatShield liner over time. We verify the flue size against the appliance before we resurface. Sometimes a stainless liner is the honest answer instead. Call (833) 365-6591 and we’ll check it.
Expect us to work from the gangway and the flat rear roof, with ladders and equipment carried through narrow side passages. We’ll set up drop cloths inside, run the camera first, clean the flue to bare masonry, and then mix and apply the Cerfractory. The application takes a day for most Belmont Cragin chimneys. You’ll get photos of the flue before and after. Call (833) 365-6591 to get a time estimate for your specific setup.

On a two-flat off West Fullerton, our tech found the furnace and water heater sharing a flue with a disconnected fireplace, pulling exhaust back into the unit and leaving the original single-wythe brick unlined. We pulled the old damper assembly, cleaned the flue to bare masonry, and applied HeatShield Cerfractory to restore a smooth, rated liner, then reset the crown with HeatShield crown coating and fitted a new stainless multi-flue cap. The back-drafting stopped and the owner had a documented Level 2 inspection for the closing. A clean chimney doesn’t announce itself – and neither does the problem you avoided by having one.
