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 Naperville, IL | Summit Peak Chimney Sweep
We provide independent DuraFlex sales & service across Naperville, handling everything from routine sweeps to full reline work on these prefab fireplace systems. What makes our DuraFlex work different here is straightforward: Naperville’s 1990s and 2000s subdivision stock, especially in White Eagle and Tall Grass, puts these units through a specific kind of wear that a generic chimney company won’t recognize until it’s expensive. We do. That means faster diagnosis, the right parts on the first visit, and a cleaning that actually holds. Call (855) 382-3714 to book.
Why Naperville Residents Choose Us for DuraFlex Service
Norm Bledsoe, our owner, has spent the better part of two decades working chimneys across the southwest suburbs, and Bolingbrook has been home base the whole time. He grew up near Springbrook Prairie Forest Preserve and still walks those trails when the season slows down. He picked up the fundamentals of heating systems and building construction at Joliet Junior College, where hands-on coursework gave him a solid grounding in how structures actually behave before he ever touched a flue brush. That background matters when we’re standing in a Naperville living room looking at a DuraFlex unit that’s been burning hard for twenty-five winters, and it matters just as much for DuraFlex in Bolingbrook where Norm started out.
We’re not manufacturer-affiliated or authorized. We’re an independent shop that services these systems because we’ve learned them the hard way, job by job. That independence means we’ll tell you when a part can wait, when it can’t, and whether OEM or aftermarket makes sense for your specific unit. We stock DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield materials, because we carry what the job actually needs, not whatever fits in the van.

Common DuraFlex Chimney Cleaning Problems We Solve in Naperville
- Heavy creosote in firebox and flue: The original owners in 60564 and 60565 are still burning these 1990s-era DuraFlex fireplaces regularly after 20 to 30 years. That usage pattern builds a dense, glazed creosote that a basic brush-and-vacuum won’t touch. We remove it with mechanical methods matched to the flue’s condition, not guesswork.
- Cracked chase covers and rusted caps from freeze-thaw: Naperville’s January freeze-thaw cycles hit exposed chase tops hard, especially on windy lots in White Eagle and Ashbury. We routinely find cracked crowns and rusted metal on DuraFlex units that look fine from the ground. The fix is a cap replacement, not another sweep.
- Failed firebox panels and refractory mortar: Prefab fireplaces from this era used panels that deteriorate with heat cycling and moisture. When we clean a DuraFlex unit in Naperville and see crumbling mortar or hairline panel cracks, we flag it immediately. A cleaning won’t fix it; a panel replacement will.
- Animal nests and debris blocking the flue: After a Naperville winter, chase covers and caps that took wind and ice often leave gaps. Birds and squirrels find them. A blocked DuraFlex flue isn’t just a draft problem, it’s a carbon monoxide risk if you’re burning gas. Our Level II inspection catches this before it becomes a call in the middle of February.
- Water intrusion from compromised chase tops: Rusted chase covers let water run down into the firebox and flue. In Naperville’s humid summers, that moisture accelerates panel deterioration and creates a smell you can’t always place when the fireplace is cold. We diagnose the source, then repair the cap and seal the crown properly.
DuraFlex Service in Naperville: What Local Conditions Mean for Your Equipment
Here’s a fact that would not be equally true in a neighboring city: Naperville’s 60564 and 60565 ZIPs contain one of the largest concentrations of 1990s-2000s subdivision homes in the region, and the DuraFlex units in those houses are now hitting the age where the original chase covers fail together, almost on schedule. In White Eagle and Tall Grass specifically, the chase covers face prevailing winds from across open retention ponds and former farmland. That exposure accelerates rust on the metal and cracking in the crown mortar at a rate you simply don’t see in, say, the tree-lined lots of Downers Grove or older neighborhoods where our DuraFlex service in Lisle handles different wear patterns. What it means for DuraFlex owners is this: if your unit is over 20 years old and you’ve never had the chase cover looked at, the odds are high that your next cleaning will turn into a cap replacement. We’d rather find that on a 60-degree spring day than after the first ice storm in January. The inspection takes the same visit either way.
DuraFlex Models & Products We Service in Naperville
We service the full range of DuraFlex lines common to Naperville homes: the SS Series, a workhorse of 1990s prefab construction with a stainless flue and modular firebox; the DirectVent Pro, often paired with gas inserts in direct-vent setups across newer eastern subdivisions; and the DuraPlus, an insulated chimney system found on freestanding stoves in both new and remodeled homes. For critical components like firebox panels and caps, we use OEM DuraFlex parts when they’re available. For standard items like dampers and flashing, a high-quality aftermarket part often does the job better for less. We stock the common sizes locally, which means faster Naperville turnaround when your unit needs more than a sweep. And when the flue liner itself is going, we carry DuraFlex flexible liner systems in inventory to handle reline work that would send a less-equipped competitor looking for a subcontractor.

AfterDuraFlex Service Pricing in Naperville
A standard DuraFlex chimney cleaning and Level II inspection in Naperville typically runs $225 to $375, depending on flue condition and how long it’s been since the last service. Creosote removal in a heavily glazed unit adds $100 to $200.

If the flue liner has deteriorated, a reline with DuraFlex SS Series liner runs $1,800 to $4,200, which is the point where we’ll sit down with you and talk repair versus replacement honestly. A free estimate includes the camera inspection so you can see exactly what we’re recommending and why. Call (855) 382-3714 to get a number for your unit.

FAQs – DuraFlex Chimney Cleaning in Naperville
Every 40 to 50 burns, or once per burning season, whichever comes first. For most Naperville homeowners burning October through April, that means an annual Level 2 inspection and cleaning. The climate here, long cold winters and humid summers, accelerates creosote hardening and crown deterioration, so skipping a year matters more than it would in a milder region. Call (855) 382-3714 to get on the schedule.
Freeze-thaw cycles around January, plus continuous wind exposure on lots like those in White Eagle and Tall Grass, where the chase faces prevailing winds across open ground. Water finds its way into the seams and rusts the metal from the inside out. Once the crown cracks and water gets under the chase cover, the rust accelerates. If you see orange streaks on your siding below the chase, the cover is already compromised and needs replacement, not paint. Call (855) 382-3714 and we’ll inspect it.
Yes, in most cases. We source OEM DuraFlex firebox panels when they’re still manufactured for your model, and we carry aftermarket panels in common sizes for Naperville’s 1990s-era units. This is a repair, not a full fireplace replacement, and it typically runs $400 to $900 depending on the panel count. If the firebox has multiple failed panels and the unit is over 25 years old, we’ll be straight with you about whether replacement makes more financial sense. Call (855) 382-3714 for a quote.
We do, and in Naperville this is one of the most frequent services for DuraFlex units. We install OEM DuraFlex caps where specified, or a high-quality aftermarket cap in standard sizes, plus custom multi-flue caps for larger chase openings. The cap is what’s standing between your flue and Naperville’s freeze-thaw cycle, so this is not the place to cheap out. Our field crews handle cap replacement on the same visit as the cleaning when we find rust or cracking. Call (855) 382-3714 to book an inspection.
The best way is mechanical removal with rotary tools sized to the flue diameter, done by someone who understands the liner’s condition before they spin a chain on it. If the creosote is glazed and hard, chemical treatment softens it over several days, then mechanical removal clears it. In Naperville, where long burning seasons produce heavy buildup in DuraFlex units, we schedule a Level 2 inspection first so we know what we’re working with. The one acceptable shortcut is to call (855) 382-3714 and have us handle it properly.
