Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
DuraFlex Chimney Cleaning in Evanston, IL | Sandstone Chimney Sweep
We provide independent DuraFlex chimney cleaning and inspection across Evanston, from the lakefront Victorians to the mid-century ranches west of Ridge Avenue. The DuraFlex issue we see most in this city is corrosion at the liner-to-cap connection, driven by Lake Michigan’s moist air working on stainless steel for years at a time. A proper cleaning here has to account for that specific wear pattern, not just the creosote inside the flue. Call (833) 589-7835 for a free estimate on DuraFlex service in Evanston.
Why Evanston Residents Choose Us for DuraFlex Service
Sandstone Chimney Sweep works with professional-grade liner systems the way an HVAC contractor works with commercial equipment, not whatever ships cheapest. We stock DuraFlex components and understand how their liners behave inside Evanston’s older chimneys, because we’ve opened enough of them to know what holds up and what doesn’t. Our relationship with DuraFlex is simple: we’re an independent service provider. Not manufacturer-affiliated, not authorized. That independence matters when we tell you a liner is fine, because we have no incentive to sell you a replacement you don’t need. Norm Sobieski, our owner, grew up in Albany Park and learned the mechanical side of the trade through the HVAC and building systems program at Truman College. He and the team bring the same measured approach to every Evanston job: find the issue, show you the evidence, and tell you plainly what the flue needs.
We handle cleaning, inspection, and repair under one roof. The technician who finds a cracked DuraFlex tee or a glazed liner is the same company that fixes it. No gap between the sweep and the contractor. For Evanston homeowners who rely on a fireplace through long, damp winters—and for those needing DuraFlex repair in Rogers Park or nearby—that continuity means a diagnosis comes with a plan, not a referral.

Common DuraFlex Chimney Cleaning Problems We Solve in Evanston
- Corrosion at the liner-to-cap connection. Moist air off Lake Michigan settles on the stainless steel cap and the joint below it. Over several seasons, that connection rusts and weakens. We find rust streaks running down the flue tile on homes from Judson Avenue to the lakefront, and we replace the failing section before it becomes a draft or water-intrusion problem.
- Freeze-thaw damage to insulated liners. A DuraFlex insulated liner relies on a factory-applied insulation blanket to keep flue gases warm and moving. Evanston’s winters cycle between freezing nights and thawing days, and that repeated expansion and contraction cracks the insulation. A cracked blanket means a cooler flue, which means creosote glazes the interior faster. We remove the glaze and recommend whether the liner can be saved.
- Crushed or dislodged DuraFlex cap screens. Heavy snow and ice sliding off Evanston roofs damages cap screens more often than people realize. A bent screen lets rain, birds, and squirrels into the flue. During our Level 2 inspection, we check the cap from the roof, not just from the ground. If it’s compromised, we install a genuine DuraFlex Pro Screen.
- Loose or degraded tee fittings in short flues. Mid-century ranches and bungalows in northwest Evanston often have shorter chimneys with a tee connection at the base. When that tee fitting loosens or corrodes, creosote collects at the bottom cleanout and draft suffers. This is one of the most common DuraFlex issues on those 1950s and 60s homes.
- Creosote glazing from modern inserts. Homeowners who install high-efficiency fireplace inserts into an older Evanston chimney frequently push more heat through a liner that wasn’t sized or insulated for it. The result is glazed creosote, which is hard, shiny, and combustible. We remove it with the right mechanical tools and explain what the liner needs to handle the insert long-term.
DuraFlex Service in Evanston: What Local Conditions Mean for Your Equipment
In Evanston’s Ridge Historic District, many DuraFlex liners were pulled through original 1920s clay tile chimneys that still contain abandoned oil flues from the 1940s coal-to-oil conversion era. That’s not a detail you’ll find on a generic DuraFlex service page, and it changes how a cleaning and inspection should be done here. An abandoned oil flue behind a fireplace creates a hidden passage for downdrafts, moisture, and pest intrusion, and it’s exactly the kind of thing a standard sweep misses. On a DuraFlex job in that district—or during DuraFlex repair in West Ridge—we check for secondary flue penetrations and cap or seal any abandoned oil flue we find. Skipping that step can leave a homeowner with a clean liner and a fireplace that still smokes. That’s the difference between cleaning a flue and actually understanding the chimney it lives inside.
DuraFlex Models & Products We Service in Evanston
We service the complete residential DuraFlex lineup: the SS Flex Kit in 6″ and 8″ stainless steel, the Insulated Flex Liner, the Pro Screen and Cap, and the Tee and Elbow Kits. For critical connections like caps, tees, and elbows, we use genuine DuraFlex replacement components so the system maintains its original fit and corrosion resistance. For less critical stainless steel fittings, we use high-quality aftermarket parts when they meet or exceed OEM specifications. We carry a stock of common DuraFlex parts for fast turnaround on Evanston jobs and DuraFlex in Skokie. It means a damaged cap or tee doesn’t have to wait a week on a parts order. If your liner is cracked or the corrosion has gone through the wall, we’ll tell you honestly that replacement is the safer, more cost-effective move. If a repair extends the liner’s life, we’ll say that too.

AfterDuraFlex Service Pricing in Evanston
DuraFlex chimney cleaning in Evanston typically falls between $180 and $340 depending on chimney height, liner condition, and whether glazed creosote or cap work is involved. A Level 2 inspection, which we recommend after any heavy snow year or before buying an older Evanston home, runs higher because it includes a camera scan of the full liner interior. What drives the cost here is access: three-story Victorians in the Ridge Historic District take more setup than a single-story ranch west of Asbury. We quote a flat price before any work begins, and the estimate includes the camera inspection and a photo report so you can see what we see. Call (833) 589-7835 for an exact quote. Estimates are free.

FAQs – DuraFlex Chimney Cleaning in Evanston
The repeated freezing and thawing of moisture around your liner stresses the insulation blanket and the liner-to-cap connection. Cracks in the insulation reduce draft, which leads to faster creosote buildup. We address it by inspecting for blanket damage during every cleaning and advising on cap replacement if the joint has rusted. Call (833) 589-7835 to schedule an inspection.
Leave it alone and have it inspected. An abandoned oil flue from a 1940s conversion is common in Evanston’s older homes, and it can create downdrafts or pest entry points if left open. We cap and seal these during a Level 2 inspection, which is the only way to see the full liner path. Call (833) 589-7835 for a free estimate on an inspection.
Not until the cap and upper flue have been checked. Heavy snow and ice routinely crush cap screens and let water into the flue, which leads to corrosion and creosote problems. A post-winter inspection catches that damage before your first fire. Call (833) 589-7835 and we’ll get on the roof and look.
Yes. Glazed creosote is hard, shiny, and difficult to remove with standard brushes, but we use mechanical tools designed for it. The bigger question is why the liner is glazing in the first place, and that usually comes back to insulation or draft. We clean the liner and explain what it needs to handle the insert long-term. Call (833) 589-7835 for an exact quote.
For the cap specifically, we use genuine DuraFlex Pro Screen replacements. The cap takes the brunt of Evanston’s lake moisture and ice, and that’s a connection worth keeping OEM. For less critical stainless steel fittings, we use high-quality aftermarket parts when they meet or exceed spec. Call (833) 589-7835 for a free estimate.
