HeatShield Chimney Cleaning in Logan Square, IL | Wexford Chimney Sweep
We’re an independent HeatShield service provider working throughout Logan Square’s 60647 zip code, and the short answer is this: HeatShield resurfacing and chimney cleaning here isn’t a generic liner job. It’s work shaped by the neighborhood’s 1890s – 1920s two- and three-flat stacks, where original unlined brick channels and shared flues mean every job starts with a real inspection, not a sales script. If you need HeatShield service, a Level 2 inspection, or an honest read on whether your flue can be restored, call us at (866) 361-2607. We also handle HeatShield sales & service across Cook County.
Why Logan Square Residents Choose Us for HeatShield Service
HeatShield is a specialty product, and we’ve spent years applying it to the kind of masonry most companies only see in photos. Logan Square’s greystones and workers’ cottages don’t have modern, round flues. They have square or rectangular brick channels, often shared between units, sometimes still carrying coal-era soot. Applying HeatShield Cerfractory Flue Sealant to that kind of flue means brushing to bare masonry first, checking the ash-pit cleanout in the basement, and knowing which joints are actually reachable. Our owner, Norm Sulecki, has been working on chimneys in this part of Cook County for close to two decades, and he’s built the company around telling homeowners exactly what he sees. If a flue can be restored, we say so. If it needs a reline, we say that instead. We don’t sell a coating just because it’s on the truck.
We use genuine HeatShield refractory materials for the liner work itself, because aftermarket sealants don’t survive Logan Square’s freeze-thaw cycling. But we’re not tied to a manufacturer program, and that independence matters. It means the recommendation comes from what’s actually in your chimney, not from a quota.

Common HeatShield Chimney Cleaning Problems We Solve in Logan Square
These are the failure modes we see regularly, and they’re tied to the specific housing stock and weather here, not just generic wear:
- Crumbling mortar under HeatShield coatings. Many Logan Square two- and three-flats have original unlined brick channels that were never sound to begin with. We find spalling brick under the coating, which means the prep work wasn’t done right, or the underlying flue was too far gone before the HeatShield went on.
- Blistered liners from freeze-thaw water intrusion. Logan Square’s cold, snowy winters push water into cracked crowns and exterior brick. When that water reaches a heat-treated liner, it blisters the coating from behind. Crown repair before resurfacing isn’t optional here; it’s the only way the work lasts.
- Misaligned tile joints in shared stacks. A three-flat with three separate flues often gets a single HeatShield treatment across the whole stack, but each channel needs its own prep. If tile joints are misaligned or offset between floors, the coating misses them entirely. We inspect per flue, not per chimney.
- Hard creosote from coal-to-gas conversions. A lot of these cottages and flats burned coal for decades before converting to gas. The shallow flues in workers’ cottages hold hard, glazed creosote that will pinhole a HeatShield coating if it isn’t brushed to bare masonry first. We do the brushing before we quote.
- Undiscovered unlined channels feeding upper units. This is the one that catches people off guard. A shared stack can look fine from the roof, but the flue serving the top unit may have never been relined at all. Without a Level 2 inspection, it’s easy to coat the wrong channel and think the job’s done.
HeatShield Service in Logan Square: What Local Conditions Mean for Your Equipment
Here’s something you won’t find on a manufacturer’s brochure: many Logan Square two- and three-flats still have the coal-era ash-pit cleanout behind the boiler in the basement. That door is often the only access point for inspecting the bottom of a HeatShield-lined flue on a shared stack. We check it before quoting any resurfacing work, because what’s visible from the roof doesn’t tell you what’s happening at the base of the channel. A flue can look sealed at the top and be spalling badly at the bottom, especially in a greystone stack that’s carried moisture for a century. Skipping that basement check is how people end up with a HeatShield job that fails in two winters. We pull the door, inspect the channel, and then tell you what’s actually needed, per flue, not per building.
One example: on a three-flat greystone off West Armitage Avenue, our crew opened the basement ash-pit and found the flue feeding the top unit had never been relined. A cracked crown was sending water down two of the three shared channels. We brushed out the hard creosote, prepped the bare masonry, applied the HeatShield Cerfractory coating per flue, and repaired the crown so the stack stopped wicking. The owner above had been seeing soot falls for months. After the job, a Level 2 inspection showed clean, sealed channels throughout.
HeatShield Models & Products We Service in Logan Square
We work with the full HeatShield lineup, including the Cerfractory Flue Sealant for unlined and damaged masonry flues, the Resurfacing System for cracked clay tile liners, and HeatShield-Plus for restoring oversized flues to proper draft. We also handle HeatShield chimney crown and masonry repair products. When it comes to the liner itself, we use genuine HeatShield refractory materials. Aftermarket sealants don’t stand up to the thermal cycling these Logan Square stacks go through every winter. But caps, dampers, and flashing don’t need to be HeatShield-branded to be good, so we pair the genuine liner material with quality aftermarket components from trusted suppliers. That keeps the work honest and the price reasonable without cutting corners on the part that actually protects your home.

AfterHeatShield Service Pricing in Logan Square
Chimney cleaning in Logan Square typically runs between $180 and $340, and a Level 2 inspection adds to that depending on what we’re looking at. HeatShield resurfacing is quoted per flue, because on a shared stack, a three-flat means three separate channels, each with its own access and condition. The biggest cost drivers are access, the amount of prep brushing needed, and whether crown repair or tile-joint work has to happen before the coating goes on. Our free estimate includes the camera inspection and a straight answer about whether your flue can be restored with HeatShield or needs a full reline instead. Nothing is quoted without showing you what we’re seeing. Call (866) 361-2607 and we’ll set up a time to look. A clean flue isn’t a luxury, it’s just how the thing is supposed to work.

FAQs – HeatShield Chimney Cleaning in Logan Square
Yes, when the brick is sound enough to hold it. We brush the flue to bare masonry first, inspect for spalling and missing mortar, and check the basement ash-pit cleanout before recommending HeatShield Cerfractory Flue Sealant on an unlined channel. If the brick is too far gone, we’ll tell you a reline is the better call. Call (866) 361-2607 and we’ll show you what the camera sees.
Because crown repair wasn’t done before the liner work, or the crown wasn’t addressed at all. Freeze-thaw cycles in Logan Square push water into hairline cracks all winter, and once water gets behind a HeatShield coating, it blisters from the back. The crown has to be sealed or rebuilt first, or the liner work won’t last. We include crown repair in the quote whenever we see cracking.
Yes. A shared stack serving three units means three separate channels, and each one has its own access points, condition, and prep work. Treating the stack as a single surface is exactly how liners fail. We quote per flue after inspecting each channel from both the roof and the basement cleanout where possible. Call (866) 361-2607 for a per-flue estimate on your building.
HeatShield doesn’t remove creosote; it seals the flue after the creosote is gone. If a shallow cottage flue is coated with hard, glazed creosote from years of coal and wood burning, we brush it to bare masonry before any HeatShield goes on. Skipping that step is how you get pinholes in the coating. The cleaning and the resurfacing are two separate steps, and we do both.
With proper prep and an intact crown, a HeatShield liner can last 20-plus years, and the manufacturer backs the material for that range. But in Logan Square, the variables are the crown, the mortar, and whether the flue was actually brushed clean first. Get those right and the liner holds. Get them wrong and it fails in a few winters. We do the prep work that makes the difference. Call (866) 361-2607 for an exact quote, estimates are free.
