DuraFlex Chimney Cleaning in Harwood Heights, IL | Crossroads Chimney Sweep
DuraFlex chimney cleaning in Harwood Heights means more than brushing soot off stainless steel. The work here centers on 1940s-1960s brick homes with original clay-tile flues, uncapped chimneys, and fireplace inserts that get pressed into service every time the power flickers out. We service DuraFlex liners across Harwood Heights as an independent chimney company, and the one thing that makes our work different is simple: we camera-inspect the liner before we recommend anything, so you see exactly what we see. Call (877) 265-6720 to book.
Why Harwood Heights Residents Choose Us for DuraFlex Service
DuraFlex is one of the most specified stainless flexible relining systems in Chicago-area masonry chimneys, and our crew works with it constantly. We size it, insulate it, and cap it for the original clay-tile flues that dominate Harwood Heights. But we’re an independent sweep, not a DuraFlex dealer or authorized installer. That matters because our recommendation is based on what your flue actually needs, not on moving product off a shelf.
Norm Szczepanski grew up a few blocks from Kosciuszko Park on the northwest side and has been working chimneys in Belmont Cragin and the surrounding neighborhoods for going on two decades. He learned the trade through the building trades programs at Triton College in River Grove, where he first encountered DuraFlex service in River Grove, then spent years on everything from century-old brick fireboxes to modern zero-clearance inserts. Around Harwood Heights, Norm’s known for straightforward inspections. He’ll tell you exactly what your flue liner looks like, whether it’s a HeatShield resurfacing job or a full Gelco liner replacement, and why it matters before any money changes hands.
We stock genuine DuraFlex liner sections, top plates, and caps, plus quality aftermarket clamps and sealants where they don’t affect the system’s rating. When you call us for Harwood Heights service area coverage, you get a company that names the product, explains the repair method, and trusts you to follow along. No vague promises. Just specifics.

Common DuraFlex Chimney Cleaning Problems We Solve in Harwood Heights
- Crushed or kinked liner sections from old installs. If your Harwood Heights flue was relined decades ago with an uninsulated single-wall liner, we regularly find crushed or kinked sections from sloppy original installs that choke draft. The chimney looks fine from outside, but smoke backs up into the house. We camera the liner to confirm, then replace the damaged sections with properly sized DuraFlex so the flue breathes again.
- Rust-through at the top plate on shaded north-side chimneys. Harwood Heights lots are tight and the tree canopy is mature, which means many chimneys sit in shade most of the day. Moisture traps around the top plate and cap, and we see rust-through and failed top-plate seals far faster on those shaded flues than on sun-exposed ones. A new DuraFlex top plate and cap assembly usually solves it.
- Nests packed against the liner top. Uncapped flues let chimney swifts and squirrels build right against the liner. When the nest is cleared and the first fire lit, homeowners call us because the draft is terrible and they’re convinced the liner failed. What we actually find is creosote glazing on the DuraFlex wall and an obstructed flue. Clear the blockage, treat the glazing, install a cap and the draft returns.
- Glazed third-degree creosote from outage-driven insert burning. Harwood Heights still sees plenty of wood burned through fireplace inserts during power outages. Inserts overfire the flue, and we pull a Level 2 camera through DuraFlex relines here that show glazed creosote a surface sweep alone won’t remove. The chimney has to be treated, not just brushed. A clean flue isn’t a luxury, it’s just how the thing is supposed to work.
- Warped liner joints and dislodged top-plate screws from overfiring. When an insert was swapped in without a properly sized DuraFlex liner, the flue runs hotter than it was rated for. We find heat-stressed liner joints and screws backed out of the top plate. Sometimes it’s a repair. Sometimes the liner needs to be replaced with the correct size. The camera tells us which.
DuraFlex Service in Harwood Heights: What Local Conditions Mean for Your Equipment
Here’s something specific to Harwood Heights that most chimney companies won’t tell you: the village is dense and post-WWII, and a significant share of the housing stock has had minimal chimney maintenance since construction. That means many DuraFlex liners installed in the 1980s and 1990s have never been inspected, not once, since the day they went in. On a 1950s brick house off Harlem Avenue, near Schiller Park, our tech found an uncapped original clay flue with a chimney swift nest packed against an older DuraFlex single-wall liner. The first camera pass showed glazed creosote from outages the family had burned wood through. We cleared the nest, removed the glazing, and set a new DuraFlex top plate and multi-flue cap so the liner could dry between fires. The draft came back and the next sweep showed clean walls. That is the pattern around here: an old liner doing its job, but surrounded by local conditions that quietly work against it. If your Harwood Heights home has a DuraFlex liner and no records of a recent inspection, the liner itself may be fine while the cap and top plate quietly rust through. That is exactly what we look for, and exactly what we fix.
DuraFlex Models & Products We Service in Harwood Heights
We work on the full DuraFlex line you’re likely to find in Harwood Heights chimneys: DuraFlex SW (single-wall) stainless flexible liner kits, DuraFlex Pro (double-wall insulated) flexible liners, and the 316L-Ti alloy liner built for wood and fireplace inserts. That last one matters around here, because insert burning is common and the 316L-Ti alloy handles the higher flue temperatures. We also service and replace DuraFlex top-plate and multi-flue cap assemblies, which fail more often than the liner itself. Our approach to parts is straightforward: we fit genuine DuraFlex sales & service liner sections, top plates, and caps so the system stays sized and rated as one unit, and we use quality aftermarket clamps and sealants where they don’t affect rating. If your liner is intact and only the cap or top plate has failed, we repair that. A full reline is only recommended when the flue tiles are cracked or the existing liner is crushed or uninsulated. We stock common DuraFlex components for fast Harwood Heights turnaround, so a top plate or cap replacement doesn’t sit on backorder.

AfterDuraFlex Service Pricing in Harwood Heights
What you pay for DuraFlex service depends on what the camera shows. A Level 2 camera inspection in Harwood Heights typically runs between $150 and $250, which includes the video and a written report. Creosote removal on a DuraFlex liner, when glazing is present, adds $150 to $300 depending on severity. A top plate and cap replacement lands in the $200 to $450 range for parts and labor. A full DuraFlex reline, if the flue tiles are cracked or the existing liner is shot, is the bigger number: $2,500 to $4,500 on a single-story Harwood Heights home, more for two-story. But here’s the thing we tell every homeowner: we don’t recommend a reline unless we can show you cracked tiles or a crushed liner on camera. Nothing is sold sight unseen. Call (877) 265-6720 for a free estimate, and we’ll walk you through exactly what’s involved before you commit to anything.

FAQs – DuraFlex Chimney Cleaning in Harwood Heights
If the clay tiles inside are intact, you need a cap, not a liner. An uncapped clay flue takes on rain, snow, and nesting animals, and a proper cap stops that. But if the tiles are cracked, spalled, or missing sections, a DuraFlex liner is the correct fix because it creates a continuous stainless passage regardless of what the old clay is doing. The only way to know is a camera inspection, which we include with a Level 2. Call (877) 265-6720 to schedule one.
Shaded north-side chimneys stay damp long after a rain, and the top plate is the first place moisture sits. On tight Harwood Heights lots with mature trees, we see top plates and caps rust through years earlier than on sun-exposed flues in neighboring suburbs like Elmwood Park. The fix is a replacement top plate and cap, and sometimes improved flashing at the crown. We’ll show you the corrosion on camera before we touch anything.
An insert that was properly matched to a 316L-Ti DuraFlex liner is built for that kind of use. The trouble starts when the insert was installed without a properly sized liner, or the liner was never upgraded for the higher flue temperatures an insert produces. We find glazed creosote, warped joints, and dislodged top-plate screws in exactly that situation. A Level 2 camera inspection tells us whether your liner is rated for what you’re asking it to do.
A Level 1 inspection is a visual check of the accessible portions of the flue and the appliance connection, and it’s appropriate when nothing has changed since the last service. A Level 2 inspection adds a camera scan of the full liner length, which is what we recommend for DuraFlex systems in Harwood Heights when a property is being sold, after a chimney fire or lightning strike, or when the liner hasn’t been inspected in years. If we’re going to recommend work, we want the camera evidence in front of both of us.
No. We’re an independent chimney company that installs and services DuraFlex liners regularly, but we are not a DuraFlex dealer or authorized installer. That independence is useful when we’re telling you the liner doesn’t need replacing, because we’re not working against a sales quota. We recommend repairs and replacements based on what the camera shows, not on what a brand program tells us to push. Call (877) 265-6720 and we’ll give you the straight read.
