Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterDuraFlex Chimney Cleaning in Glenview, IL | Level Two Chimney Evanston
We provide independent DuraFlex service across Glenview - not manufacturer-authorized, but factory-trained on every model line and stocked with OEM liner, tee, and cap components for same-day field fitting. The one thing that makes our DuraFlex work here different is how we size and insulate around Glenview’s cracked terra cotta flues and abandoned second flues, not around a clean round hole that doesn’t exist in this town’s 1950s housing stock. Call us at (708) 234-1174 for a written estimate before any work starts.
Why Glenview Residents Choose Us for DuraFlex Service
We’ve been running camera inspections and Glenview Chimney Cleaning & Sweep services across the North Shore since 2009, and Glenview’s postwar chimneys have become a specialty by repetition. Corrine Halstead, our owner, learned the trade at Apex Technical School in Manhattan before bringing that standard to the Chicago area. She and our crew have handled enough split-level stacks off Shermer Road and ranch chimneys near Wagner Farm to know the difference between a flue that needs a sweep and one that needs a full DuraFlex reline before the camera even goes up.
We keep DuraFlex SW smooth-wall kits, pre-insulated drops, and Pro-series components in our Evanston warehouse specifically for Glenview’s aging masonry. That inventory means we’re not ordering parts while your chimney sits open. Every job starts with a written price, a written scope, and a written warranty under DuraFlex sales & service protocols - Clause 1 of the Haven Standard. The camera record, Clause 4, follows automatically. We’ve completed more than 38,000 inspections and cleanings, and not one began without that written price in the customer’s hand first.
Common DuraFlex Chimney Cleaning Problems We Solve in Glenview
- Cracked terra cotta forcing irregular liner fit. Glenview’s 60-70-year-old clay flue tiles spall and fracture from decades of freeze-thaw cycling. The DuraFlex liner we drop has to follow a non-round, damaged path, so an uninsulated or mis-sized kit drafts poorly and condenses moisture back into the masonry. We field-measure with a video scan, then specify the exact SW or insulated diameter with proper packing.
- Water intrusion through crown cracks rusting top terminations. Chicago’s winter temperature swings open mortar joints and split chimney crowns above Glenview’s rooflines. Rain runs down the outside of the DuraFlex liner and corrodes the clamp, top plate, or tee cap. Our fix is crown repair or replacement plus a stainless termination, not just a new liner left exposed to the same leak.
- Glazed creosote in occasional-use fireplaces. Glenview homeowners tend to burn for atmosphere, not heat. Those low, smoldering fires deposit Class III glazed creosote on the DuraFlex inner wall. The first hot fire of the season flashes it off. We remove that glaze with mechanical cleaning and verify the liner surface with camera before signing off.
- Abandoned second flues collecting debris and moisture. On 1950s-era blocks near downtown Glenview and Wagner Farm, we regularly find the original furnace flue left open after HVAC conversion. Nests, leaves, and saturated debris pile up against the active DuraFlex liner, accelerating masonry deterioration. We cap these with a Multi-Flue Cap and document the condition under Clause 4.
- Direct-vent gas inserts in The Glen mismatched to existing flues. The newer homes near Glen Town Center often have gas inserts that don’t need a full DuraFlex liner but do need proper venting and clearance verification. We inspect to NFPA 211 Level 2 and specify only what’s actually required - no oversell on a liner that doesn’t fit the appliance category.

AfterDuraFlex Service in Glenview: What Local Conditions Mean for Your Equipment
In Glenview’s 1950s-era blocks near downtown and Wagner Farm, it’s routine to find a two-flue chimney where one flue served the original oil or coal furnace and was never capped after the HVAC upgrade - so we’re often cleaning, capping, and documenting an abandoned flue alongside the active fireplace flue on the same visit. This isn’t a curiosity. It’s a pattern we’ve mapped across dozens of inspections, and it shapes every DuraFlex recommendation we make. The active flue may need a properly sized and insulated DuraFlex SW liner dropped through spalled terra cotta; the dead flue needs a Multi-Flue Cap to stop water and vermin entry, not a second liner that serves no appliance. Getting this distinction wrong - lining both flues, or capping neither - wastes money and leaves the chimney structurally compromised. We make the call with the camera running and the homeowner watching, because the footage shows what words can’t. The camera doesn’t negotiate - and neither does creosote.
DuraFlex Models & Products We Service in Glenview
We stock and service the full DuraFlex line: SW smooth-wall stainless flex liner kits for wood-burning fireplaces with heavy creosote loads; pre-insulated DuraFlex Insulated kits for exterior chimneys exposed to Glenview’s hard winters; DuraFlex Pro and LD flexible liners for tight flue paths and offset conditions; and direct-vent plus insert liner components for gas and wood insert conversions common in The Glen’s newer construction. We use DuraFlex OEM liner sections, tees, and terminations because UL listing and proper fit depend on exact system matching. For crowns, caps, and masonry repairs we source quality aftermarket components through our Haven buying network that meet the same code without inflating the price. If your existing liner is sound and correctly sized, we repair. If the flue is fractured, undersized, or uninsulated, we recommend a proper DuraFlex reline rather than patching a system that’s already failed.

Our Glenview service area pricing follows the same structure we use across northern Cook County, adjusted for the specific DuraFlex components and labor your chimney requires:

What drives cost: flue height, number of offsets, whether the terra cotta must be removed or can stay in place, and whether the abandoned second flue needs capping.

FAQs - DuraFlex Chimney Cleaning in Glenview
The terra cotta flue tiles in 1950s Glenview chimneys have reached end of life. Freeze-thaw cycles fracture the clay, and low-heat fires produce acidic condensation that erodes the mortar between tiles. A sweep removes creosote but can’t restore structural integrity to fractured terra cotta. We camera-scan to confirm spalling or cracking, then specify a DuraFlex liner sized to the actual flue condition. Call (708) 234-1174 for a free inspection and written estimate.
It’s almost certainly the original furnace flue, left unused after your HVAC was converted to gas forced-air or heat pump. We find these open and uncapped on nearly every 1950s block near downtown Glenview and Wagner Farm. An abandoned flue doesn’t need a liner - it needs a proper cap to stop water, debris, and animal entry. We install Multi-Flue Caps that seal the dead flue while venting the active one. Call (708) 234-1174 and we’ll show you on camera exactly what you have.
Direct-vent gas inserts typically use their own coaxial venting and don’t require a DuraFlex liner in the existing chimney. We inspect to confirm proper clearances, vent termination height, and chimney condition per the appliance manufacturer’s listed requirements. If the existing flue is intact and the insert is correctly vented, no liner is needed. We won’t sell one that doesn’t serve the installation. Call (708) 234-1174 for a Level 2 inspection specific to your appliance.
Water enters through crown cracks or failed flashing, freezes, expands, and opens the masonry further - a problem our Chimney Repair - Glenview team addresses at the source. That same water runs down the outside of the DuraFlex liner and rusts stainless clamps and top plates over seasons. An uninsulated liner in an exterior chimney accelerates the problem because flue gases cool too quickly, producing more condensation. We specify pre-insulated DuraFlex for exterior applications and always inspect the crown, flashing, and termination as part of the liner installation. Call (708) 234-1174 for a winter-readiness inspection.
Yes. Infrequent use is actually harder on flues than regular firing because low-heat fires produce the most creosote and the least drying effect on masonry. That glazed creosote builds silently, and the first hot holiday fire is when chimney fires happen. We recommend annual Level 2 inspection with cleaning as needed, documented under Haven Standard Clause 4. Call (708) 234-1174 to schedule before burning season.
