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 Lemont, IL | Summit Peak Chimney Sweep
We provide Lemont Chimney Sweep services for independent DuraFlex cleaning and repair across the area, and the work here splits into two distinct patterns: century-old limestone chimneys downtown that need careful liner evaluation, and newer factory-built units in the quarry-land subdivisions that need a different touch entirely. If you own a DuraFlex system in Lemont, you already know it’s not a one-size-fits-all service. Call us at (855) 382-3714 and we’ll tell you exactly what your flue needs after a proper inspection, not before.
Why Lemont Residents Choose Us for DuraFlex Service
Most chimney companies can sweep a flue. Far fewer can tell you whether the DuraFlex liner inside it is still doing its job. Norm Bledsoe, our owner, has spent nearly two decades working chimneys across the southwest suburbs, and a lot of that time has been spent looking at liners that were either installed wrong, deteriorating, or never evaluated after the original install. He got into this trade through the diagnostic side, the part where you find out why a flue isn’t drafting and what material actually fixes it.
We carry DuraFlex components from professional suppliers, not whatever the hardware store had on the shelf. That matters in Lemont because the housing stock runs from original 1800s clay-tile flues to modern DuraFlex prefab systems, and the right part for a 1990s direct-vent unit isn’t the same as the right part for a SureFlex liner retrofitted into limestone. We stock what these jobs actually need, and we show you what we found, with photos, before recommending anything. A clean flue is the whole job, everything else is just finding out why it isn’t.
We’re also a full DuraFlex sales & service resource for the area, which means the same crew that cleans your chimney can also evaluate and replace failed components.

Common DuraFlex Chimney Cleaning Problems We Solve in Lemont
- Cracked flue tiles in older DuraFlex prefab fireplaces. Lemont winters bring repeated freeze-thaw cycles, and when moisture gets into the chimney chase it freezes, expands, and cracks ceramic flue tiles. We see this most often in units from the 1990s and early 2000s where the original cap or flashing has failed. The fix usually means replacing the damaged tile with an OEM DuraFlex part before the crack spreads into the surrounding structure.
- Corroded outer shells on direct-vent units. Heavy snow and ice on a DuraFlex direct-vent termination can force moisture past a worn cap or gasket. Once water gets inside the outer metal shell, corrosion follows. We’ve pulled apart units in Lemont subdivisions where the outer shell was rusting from the inside out while the homeowner had no idea anything was wrong.
- Creosote buildup in stainless liners. Burning unseasoned wood, or wood that hasn’t dried properly, produces a dense, sticky creosote that clings to the corrugated walls of a DuraFlex stainless liner. We see this often in the older homes around Lemont’s historic core where fireplaces get used heavily through the winter. This buildup isn’t just dirty, it’s fuel. We remove it with the right brushes and solvents for stainless, never wire wheels that could score the liner.
- Damper and gasket failure letting cold air in. A failed gasket on a DuraFlex direct-vent unit doesn’t just waste heat, it can let combustion gases back into the house. During a cleaning, we check every gasket and damper for proper seal. If it’s worn, we replace it. It’s a small part that makes a big difference in both safety and heating cost.
- Debris migration from adjacent flues in shared-wall buildings. Downtown Lemont has attached limestone buildings where chimneys share party walls. Loose soot and crumbling mortar from one flue ends up in the neighboring one. If you’re in a historic building and your draft suddenly goes bad, we check what’s coming through from the other side.
DuraFlex Service in Lemont: What Local Conditions Mean for Your Equipment
Here’s what makes Lemont different from Bolingbrook, Darien, or nearby communities served by DuraFlex in Burr Ridge. In the historic downtown, a lot of DuraFlex liners were retrofitted into original 1800s limestone chimneys. We’re not talking about modern construction with a clean clay tile interior. We’re talking about century-and-a-half-old stonework with mortar joints that have seen 150 winters. When we clean one flue in a shared-wall building, we often find debris that migrated from the adjacent unit’s flue, soot, crumbled mortar, even old bird nests that shifted through gaps in the party wall. That means we isolate the flue we’re working on, inspect the shared wall penetration, and document what came from where. You can’t wire-brush these chimneys aggressively. The mortar’s too old and the stone’s too soft. We hand-clean what needs hand-cleaning and use mechanical brushes only where the liner and surrounding masonry can take it. If you own a DuraFlex setup in a downtown Lemont building, your cleaning needs to account for the structure around the liner, not just the liner itself.
DuraFlex Models & Products We Service in Lemont
We clean and repair the full range of DuraFlex systems you’ll find in Lemont homes: the ReliaGlo Series, the Direct Vent Series, the SureFlex Liner, and the Pro-Vent Series. We use genuine DuraFlex parts for critical components, flue tiles, dampers, and liner sections where the fit and material spec matter for safety. For wear items like gaskets and caps, we’ll use high-quality aftermarket equivalents when it makes sense for your budget and the chimney’s condition. We keep common DuraFlex components stocked so most Lemont repairs don’t wait on a parts shipment. If your prefab unit needs a new refractory panel or your SureFlex liner needs a section replaced, we can typically get it done without multiple trips.

AfterDuraFlex Service Pricing in Lemont
Chimney cleaning in Lemont typically runs $190 to $290 for a standard DuraFlex prefab or lined flue. A Level 2 inspection, which we recommend if you’ve had a chimney fire, recently bought the home, or haven’t had the liner evaluated in years, adds $150 to $300 depending on the system and access. Cap replacement runs $250 to $450 for most DuraFlex terminations, more if it’s a custom multi-flue cap for a shared-wall downtown chimney. Creosote removal from a heavily glazed stainless liner can push the cleaning cost higher because it takes time and solvents, not just brushes. The estimate is free. We’ll tell you what it costs before any work happens, and we’ll show you photos of what we found. Call (855) 382-3714 and we’ll give you an exact number for your chimney.

FAQs – DuraFlex Chimney Cleaning in Lemont
Once a year if you burn wood regularly, which most Lemont homeowners with fireplaces do from October through March. If you only burn occasionally, every two years is usually sufficient, but we still recommend an annual visual check because the freeze-thaw cycles here are hard on caps, flashing, and masonry. The cleaning itself takes care of creosote; the check catches problems before they need a repair call. Call (855) 382-3714 to schedule your next cleaning, we book faster in early fall before the burning season hits.
Poor draft that doesn’t improve after cleaning, visible rust or corrosion on the liner surface, loose soot falling into the firebox between cleanings, or a strong smell from the chimney when the fireplace isn’t in use. If we find holes, deep pitting, or separated seams during a Level 2 inspection, we’ll show you the camera footage and walk through whether a targeted repair or full replacement makes sense. We don’t recommend replacement, we document the need for it. Call (855) 382-3714 for an inspection if you’re seeing any of these signs.
Yes, and we do it regularly. In downtown Lemont’s attached limestone buildings, we isolate your flue, inspect the party wall penetration, and use hand-cleaning methods where the original mortar can’t handle mechanical brushing. We’ll also check whether debris from adjacent units is migrating into your liner, which is common in these older shared-wall structures. Call (855) 382-3714 and let us know you’re in the historic district, we’ll approach it accordingly.
We do. Lemont gets real snow and ice, and a standard cap sometimes doesn’t handle the snow load on a shared-wall downtown chimney or an exposed roof in a subdivision. We’ll measure your DuraFlex termination and install a cap sized for your specific exposure, with a spark arrestor screen that keeps animals out while venting properly. If your current cap is rusting or letting water past, don’t wait for the next freeze cycle to make it worse. Call (855) 382-3714 for a cap assessment.
No. We’re an independent DuraFlex service provider, not affiliated with or authorized by the manufacturer. That independence means our recommendations are based on what your chimney actually needs, not what a manufacturer program tells us to push. We use genuine DuraFlex parts where they matter and aftermarket equivalents where they don’t, always with an eye on your budget and the chimney’s condition. Call (855) 382-3714 and we’ll give you an honest assessment.
