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 Westmont, IL | Summit Peak Chimney Sweep
We’re an independent Westmont Chimney Sweep and DuraFlex service provider, and the quick answer is this: DuraFlex chimney cleaning here isn’t just about removing creosote. Most 60559 chimneys were built for oil heat in the 1940s through 1960s, so a proper cleaning means checking whether the liner still matches the appliance now connected to it. That’s the difference in how we approach DuraFlex work across Westmont.
We stock genuine DuraFlex components and know how these flexible stainless liners behave inside mid-century masonry. If you need a sweep, a Level 2 inspection, or liner work, call (855) 382-3714. Norm Bledsoe and our crews handle DuraFlex sales & service with the same parts commercial contractors trust.
Why Westmont Residents Choose Us for DuraFlex Service
We’ve spent the better part of two decades running chimneys across the southwest suburbs, and Norm Bledsoe has seen almost every way a liner can fail in this climate. The homes here, ranches and split-levels mostly, were framed when oil was cheap and gas conversion was a retrofit. That history shows up in the flue every time we run a camera.
What sets our Westmont service area work apart is that we inspect before we clean. A sweep that ignores a spalled clay tile behind a stainless liner leaves the homeowner with a false sense of safety. We’d rather tell you what’s actually there. We carry DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield materials on the truck, so when the inspection turns up a failed cap or a separated joint, the fix doesn’t wait for a parts order.

Common DuraFlex Chimney Cleaning Problems We Solve in Westmont
- Liner corrosion from acidic flue gas. Oil-to-gas conversions leave liners sized wrong for the appliance. Gas exhaust runs cooler and wetter, so condensation sits in the flue and eats stainless over time. We see this constantly in Westmont’s 1950s colonials near downtown. A camera inspection tells us if the liner’s still sound before we sweep.
- Mechanical damage from wrong brushes. Older Westmont chimneys have rough clay tile transitions that can snag a flexible liner if whoever’s sweeping uses a steel brush or the wrong diameter. We match brush type to the liner, and we’ve pulled more than one damaged liner out of a flue where a previous company didn’t. DuraFlex liners survive decades when they’re treated properly.
- Top plate and cap seal failure. Northern Illinois freeze-thaw cycles crack masonry crowns, and once water gets past the top plate, the liner’s exterior starts corroding from the outside in. Westmont winters are hard on caps. We check the termination every visit and replace seals with genuine DuraFlex cap assemblies.
- Liner joint separation at appliance connections. The long heating season here, October through April, means constant thermal cycling. Joints at the appliance collar expand and contract until fittings loosen. A drafty fireplace or a furnace that’s suddenly throwing an error is often a separated liner joint.
- Creosote buildup in uninsulated liners. Fireplace inserts vented through uninsulated DuraFlex in an exterior Westmont chimney never get hot enough to keep creosote from condensing. The buildup is faster, the sweep intervals shorter, and the fix is often adding insulation rather than waiting for a chimney fire to make the case.
DuraFlex Service in Westmont: What Local Conditions Mean for Your Equipment
Walk the older neighborhoods near downtown Westmont and you’ll notice something: the chimneys were built for a heating era that’s gone. Those masonry flues once vented coal or oil furnaces. When the gas conversion happened, often decades ago, the chimney wasn’t resized, it was repurposed. The old flue tiles are too large for a modern gas furnace, too small for some fireplace inserts, and always too deteriorated for either. A routine sweep in these homes turns into a liner assessment because the chimney was never actually rebuilt for what it now does. If you’re in the area, our DuraFlex service in Downers Grove handles similar vintage homes with the same thorough approach.
That’s why our DuraFlex work in Westmont, like our Darien DuraFlex service, often starts with a Level 2 inspection before any brush touches the flue. We need to know if the existing liner can safely handle the current appliance. When it can’t, we say so plainly, and we install a properly sized DuraFlex stainless liner rather than patching the old one. A clean flue is the whole job, everything else is just finding out why it isn’t.
DuraFlex Models & Products We Service in Westmont
We work on the full DuraFlex line here in Westmont: Stainless Steel Flexible Chimney Liner Kits, Insulated Flexible Liner Systems, Top Plate and Cap Assemblies, and Fireplace Insert Liners. That covers everything from a basic oil-to-gas reline to an insulated liner for a wood stove or fireplace insert.
For critical connections and terminations, we use genuine DuraFlex OEM components. Fit matters at the top plate and the appliance collar, and the tolerance differences between OEM and off-brand parts cause avoidable failures. For non-structural elements, we’ll use aftermarket parts where they meet or exceed spec. When a liner is corroded or damaged past safe repair, we recommend replacement, not patchwork. Chimney venting isn’t the place to save money with a splice.

FAQs – DuraFlex Chimney Cleaning in Westmont
Probably, and the only way to know is a Level 2 inspection. Gas exhaust is cooler and wetter than oil exhaust, so it condenses inside the old clay flue. That acidic condensation eats masonry and corrodes liners. If your Westmont chimney still has its original clay tiles, they were sized for oil and almost always need a properly sized stainless liner before a gas furnace or water heater vents through them safely. We inspect first and show you the camera footage, so you’re deciding with evidence, not a sales pitch.
The masonry crown under your cap cracks from repeated freeze-thaw cycling, and water follows those cracks down around the liner. Once the top plate seal is compromised, moisture gets between the liner and the flue wall. That’s how stainless liners corrode from the outside even when the inside looks clean. We check crown condition and cap seal every time we’re on a Westmont roof, because the cap’s only as good as what it’s sitting on.
Yes, that’s exactly what we do. The key is using the right brush, poly or the correct diameter stainless, never a steel brush that can scratch or tear the liner’s inner wall. We also inspect the liner joints and the top plate during the sweep, because cleaning a damaged liner without reporting the damage does you no favors. Every DuraFlex-equipped chimney we clean in Westmont gets a visual liner check as part of the sweep.
Water stains on the ceiling near the chimney chase, rust-colored drip marks on the appliance collar, a persistent draft problem that doesn’t improve after cleaning, or visible corrosion pitting on the liner’s exterior during an inspection. We’ve also found liners that were mechanically damaged by improper sweeping. Corroded or torn stainless isn’t repairable. It’s replaced, because the liner is what keeps combustion gases out of your house. If you’re seeing any of these signs, call (855) 382-3714 and we’ll camera the flue to confirm.
We back our installation work and the DuraFlex components carry the manufacturer’s warranty. What we don’t do is hand you a piece of paper and disappear. If something fails on a liner we installed in Westmont, we come back and make it right. That’s the point of using OEM components and being the crew that’s still around when a warranty question comes up.
