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 Elmhurst, IL | Level Two Chimney Elmhurst
DuraFlex chimney cleaning and relining service in Elmhurst typically runs $180-$340 for a standard sweep with Level 2 camera inspection, while a full DuraFlex stainless liner installation ranges from $2,800-$4,500 depending on flue height and diameter. What sets our work apart in Elmhurst is the concentration of 1920s-1940s brick homes with original clay-tile chimneys that were never relined after gas conversion - we find cracked, unlined furnace flues on camera that a roofline visual would miss entirely. We are independent DuraFlex specialists, not manufacturer-authorized, and we stock genuine DuraFlex 316L and 304L liner kits for same-week turnaround across Elmhurst service area. Call (708) 498-3199 for a written estimate before any work begins.
Why Elmhurst Residents Choose Us for DuraFlex Service
We’ve been running cameras down chimneys in Elmhurst since 2009, and the housing stock here teaches you something fast. The brick Colonials and Tudors near the Metra corridor don’t behave like the frame construction you see west of Route 83. Corrine Halstead, our owner, grew up in Queens and learned this trade at BOCES Vocational Technical Center before relocating to the western suburbs and building a crew that has spent years working chimneys across Elmhurst, including older bungalows near the York Woods neighborhood. She has done Elmhurst Chimney Cleaning & Sweep and inspection work for over two decades.
The camera doesn’t editorialize. Neither do I. That phrase stuck because it’s how we operate. We pull the camera out first, let the footage show the cracked tile or the acidic wash pattern, then hand you a written price with the scope and warranty in front of you. No verbal estimates, no “we’ll see what we find.” Clause 1 of the Haven Standard requires a written price before work starts; Clause 4 requires a documented photo record on every job. We’ve done that since 2009, on every one of the 38,000+ chimneys we’ve inspected.
We stock DuraFlex sales & service components locally - 316L and 304L liner kits, insulated systems, top plates, and appliance connectors - because DuPage County’s freeze-thaw cycles punish aftermarket substitutes. When we recommend a repair over a full reline, it’s because the camera footage supports it, not because we’re cutting corners.
Common DuraFlex Chimney Cleaning Problems We Solve in Elmhurst
- Stress corrosion cracking at liner seams and top plate connections. This shows up in Elmhurst’s oversized, unlined furnace flues - the ones that were never relined after coal-to-gas conversion in the 1960s and 1970s. Acidic flue gas condenses in the oversized clay tile, attacks the stainless seam, and we find pinhole leaks on camera that a roofline visual would call “fine.”
- Mechanical abrasion and pinhole wear against jagged clay tile edges. Elmhurst’s 30-40 annual freeze-thaw cycles spall the soft mortar and clay tile in these pre-WWII chimneys. A flexible DuraFlex liner expands and contracts against those sharp edges. We see this most in the dual-flue chimneys along Cottage Hill Avenue, where the original construction left rough offsets.
- Corrosion of the liner’s outer wrap and top plate from wind-driven rain. The open suburban grid here leaves rooftop chimneys exposed to sustained northwest winds off the plains. Mortar washout under the cap accelerates compared to sheltered Chicago neighborhoods. We inspect for this every time we clean, because a compromised top plate lets water track down between the liner and the clay tile.
- Insulation blanket degradation and shifting inside the liner. Tall, offset flues in 1920s-1940s brick chimneys create sag points where insulation compresses or migrates. Draft drops. Temperatures at the liner wall climb. We catch this on camera during Level 2 inspection and can re-insulate or replace sections without a full reline if the stainless itself is sound.
- Draft failure and exhaust odor from unlined secondary flues. A homeowner on Spring Road called us about a drafty fireplace and a faint exhaust smell in the basement. Our tech ran a Level 2 camera inspection and found the original 1920s furnace flue had never been relined after a 1970s gas conversion - the clay tile was cracked and coated with acidic residue. We installed a DuraFlex insulated stainless liner sized for the gas appliance, capped the chimney, and the draft and odor issues disappeared.

AfterDuraFlex Service in Elmhurst: What Local Conditions Mean for Your Equipment
In Elmhurst’s older blocks near Cottage Hill Avenue, many chimneys have a secondary furnace flue that was never relined after the home switched from coal or oil to gas. Because no permit was pulled, there’s no record of it, and only a camera inspection reveals the cracked clay tile or missing liner. This is not a theoretical risk. We’ve found it repeatedly in inspections across the York Woods neighborhood and along Spring Road - the original oversized clay tile, cracked from decades of acidic condensation, still venting a high-efficiency gas appliance that was never properly matched to the flue.
For DuraFlex owners, this matters because the liner you installed for your fireplace may be performing perfectly while the furnace flue three feet away is deteriorating unchecked. Carbon monoxide doesn’t migrate through brick reliably, but draft failure absolutely does - it can pull exhaust into wall cavities or basement spaces. Our Level 2 inspection protocol scans every flue in the structure, not just the one with the visible appliance. In Elmhurst, that’s where the real hazard hides.
DuraFlex Models & Products We Service in Elmhurst
We work with the full DuraFlex product line: 316L and 304L stainless steel flexible chimney liner kits, insulated flexible liner systems with proprietary wrap, direct vent and gas appliance liner kits, and the component line of top plates, caps, and appliance connectors. We source genuine DuraFlex OEM parts through our Haven buying network, not aftermarket substitutes that mismatch alloy grades or insulation R-value.
For Elmhurst’s pre-WWII chimneys, we typically spec 316L for oil or wood applications and 304L for gas-only liners, with insulation mandatory on any exterior wall or tall flue where draft temperature retention matters. We keep common diameters - 5″, 6″, and 7″ - in stock for same-week installation after inspection. If your flue has an offset or sharp bend, we carry the transition fittings and have the rigging experience to pull them without kinking.

FAQs - DuraFlex Chimney Cleaning in Elmhurst
No - not automatically. A roofline visual cannot evaluate the interior surface of clay tile or detect cracks hidden below the flue shoulder. We run a camera inspection first. If the tile is sound, the mortar joints are intact, and the flue is properly sized for the appliance, cleaning may be all you need. If we find spalling, cracks, or acidic wash patterns, we’ll show you the footage and give you a written price for Chimney Repair - Elmhurst or reline options. Call (708) 498-3199 to schedule - estimates are free.
DuPage County’s 30-40 annual freeze-thaw cycles spall the clay tile host that the flexible liner rests against. Jagged edges abrade the stainless surface during expansion and contraction. Water that penetrates a degraded crown or top plate can freeze between the liner and tile, accelerating mechanical wear. We inspect for this specifically in Elmhurst’s exposed rooftop chimneys and recommend waterproofing when crown integrity is compromised.
Yes. The 1920s-1940s brick chimneys common in Elmhurst frequently have offsets to avoid floor joists or stairwells. DuraFlex flexible liner is engineered for this. We use weighted pull ropes, controlled descent, and transition fittings at severe angles. We won’t install where the bend would kink the liner or create a sag that collects condensation - if the geometry won’t allow a proper installation, we’ll tell you and propose alternatives.
A Level 1 inspection is a visual examination of readily accessible portions - what we can see from the firebox and roofline without tools. A Level 2 inspection, which we perform on every DuraFlex service visit, includes a camera scan of the entire flue interior, inspection of attics and crawl spaces where the chimney passes, and documentation of liner condition, clearance to combustibles, and appliance connection integrity. Clause 4 of the Haven Standard requires this photo record on every job.
We stock genuine DuraFlex OEM components - top plates, caps, appliance connectors, and liner sections - because matched alloys and insulation specifications matter for warranty and performance. We recommend replacement when the liner shows stress corrosion cracking, multiple pinholes, or insulation degradation that cannot be remediated with a sectional repair. We recommend repair when the damage is localized and the remaining liner has documented service life. The camera footage decides; we don’t guess. Call (708) 498-3199 to review your specific situation.
