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 Palos Heights, IL | Summit Peak Chimney Sweep
DuraFlex chimney cleaning in Palos Heights is what we do most weeks from September through January, and we provide it as fully independent service for both original DuraFlex flex liners and the chimney caps and top plates that ride on them. We’re not a DuraFlex-authorized shop. What we are is a crew that has pulled apart enough DuraFlex systems in this town to know that the cleaning itself is never just about creosote here. The real job in Palos Heights is keeping oak leaves, squirrel nests, and freeze-thaw crown damage from choking out a liner that would otherwise run clean for years. Call (855) 382-3714 if your DuraFlex cap is packed or your first fire of the season smoked back into the room.
Why Palos Heights Residents Choose Us for DuraFlex Service
Most chimney companies in the southwest suburbs can run a brush down a flue. Not many can tell you whether the lock seams on your DuraFlex liner are still holding, or whether that missing insulation collar up top is actually the reason your stainless flue is pitting from the inside out. That diagnostic difference is what keeps Palos Heights homeowners calling us back. Norm Bledsoe has spent the better part of two decades working chimneys across this area, and he built Summit Peak around a simple idea: show the homeowner what’s actually wrong, fix it with the right material, and don’t upsell a reline when a $90 cap replacement solves the draft problem. We carry DuraFlex factory components alongside our brushes because the cap you pull off a 1960s Palos Heights masonry chimney is usually just as tired as the flue below it. When we sweep, we inspect. When we inspect, we explain what we found. You can see our full service area on our Palos Heights service area page.

Common DuraFlex Chimney Cleaning Problems We Solve in Palos Heights
- Packed cap screens from oak and maple leaf drop. Streets bordering the Cook County Forest Preserves and the blocks around Lake Katherine lose a shocking amount of twig and leaf load every fall. A DuraFlex stainless cap can be completely blinded by mid-November, which kills draft and sends smoke back into the living room on the first real fire of the season.
- Insulation blanket tears at the top of insulated DuraFlex liners. Squirrels love the top of a warm flue. We regularly find the insulation collar chewed and pulled back, exposing bare stainless to condensing flue gases. In Palos Heights’ cold, damp winters, that exposure accelerates chloride-induced pitting in one season.
- Lock-seam separation from years of aggressive brushing. Older DuraFlex liners installed tight around a clay-tile offset don’t tolerate oversized poly brushes. Repeated cleaning with the wrong brush opens the crimp joints. We inspect seam condition on every sweep and flag any opening before it becomes a flue gas leak.
- Creosote glaze at the smoke chamber transition. A lot of 1950s-70s Palos Heights brick ranches and split-levels still run original single-wythe fireboxes mated to a DuraFlex liner that was sized on the optimistic side. Heavy glaze builds right where the liner meets the smoke chamber. That’s a cleaning issue we address every time, and a draft issue we’ll explain if it keeps coming back.
- Rusted-through multi-flue caps on original masonry chimneys. When a DuraFlex-compatible cap sits on a 1968 brick ranch chimney for thirty years, the freeze-thaw cycles spall the crown, the leaf pack holds moisture against the mesh, and the cap rusts through. We pull it, show you the holes, and replace it with a stainless cap that fits the liner properly.
DuraFlex Service in Palos Heights: What Local Conditions Mean for Your Equipment
Here’s the thing that surprises most Palos Heights homeowners when we explain it: a DuraFlex liner in this town can look perfectly clean inside while the cap screen is packed solid with leaves. The mature oak and maple canopy over streets near the Cook County Forest Preserves and around Lake Katherine drops enough twig and leaf load every fall that the cap screens on chimneys here get blinded by mid-November. We’ve seen it repeatedly: the flue below looks fine through a borescope, but the cap screen is so choked that the fireplace can’t breathe. That’s why we pull and inspect the cap on every sweep in Palos Heights, not just brush from the top. If your cap screen is packed, no amount of liner cleaning will fix your draft. The cap comes off, gets cleared, and gets inspected for rust-through before it goes back on. On a 1963 split-level near Lake Katherine, the cap screen was packed dry oak leaves while the flue below had less than a quarter-inch of creosote. The homeowner had already tried to light two fires and given up. We cleared the cap, and the third fire drafted perfectly. The liner never needed more than a standard sweep. That’s the local reality: in Palos Heights, your DuraFlex system’s biggest seasonal enemy is usually a tree, not a fire.
DuraFlex Models & Products We Service in Palos Heights
We clean and inspect the full DuraFlex range you’ll find across Palos Heights homes: DuraFlex SS flexible chimney liner kits in 316L and 316Ti alloy, DuraFlex insulated flexible liners with pre-insulated wrap kits, DuraFlex Pro and Premium flexible relining systems, and the DuraFlex factory-built chimney components like caps, top plates, and connector kits that finish the installation. We use genuine DuraFlex replacement caps, top plates, and connector components when we fix a system, because the lock geometry and alloy match matter on a listed flex liner. Where an aftermarket UL-listed stainless clamp or mesh meets the same spec, we’ll use it and tell you why. But we don’t guess at fitment. If a DuraFlex liner shows pitting, seam separation, or missing insulation over more than a short run, we’ll say plainly that relining is the safer money compared with patching a compromised stainless flue. We’d rather tell you the truth than sell you a band-aid. For broader background on our DuraFlex work, visit our DuraFlex sales & service page.

AfterDuraFlex Service Pricing in Palos Heights
A standard DuraFlex chimney cleaning in Palos Heights runs between $179 and $279, depending on flue height, access difficulty, and creosote condition. Level II inspections here generally fall between $295 and $495, and we recommend one any time a home changes hands or a Palos Heights chimney hasn’t been opened up in five-plus years. If the cap is packed with leaves or a squirrel has been in, cap removal and screen clearing runs $95 to $175. New stainless DuraFlex-compatible caps land between $220 and $395 installed. When the inspection turns up crown damage, repairs vary widely by severity; we’ll quote it after we see the chimney, not before. Every estimate includes the camera inspection and photo report, and the price we agree on is the price you pay. If you’re on the fence about whether your DuraFlex liner needs a sweep or a full replacement, call (855) 382-3714 and we’ll tell you straight what we find.

FAQs – DuraFlex Chimney Cleaning in Palos Heights
Yes, and it’s one of the most common calls we get from Palos Heights homeowners each fall. The mature oak and maple canopy over streets near the Cook County Forest Preserves and Lake Katherine drops enough leaf litter that a DuraFlex cap screen can be fully blinded by mid-November. It doesn’t mean your liner is dirty or damaged. But a clogged cap screen kills draft and can push smoke back into the house. We clear the screen on every sweep, and if it’s rusting through or missing mesh, we’ll replace the cap so the cycle doesn’t repeat. Call (855) 382-3714 to get on the fall schedule before the first freeze.
You’ll see it in the inspection, not the cleaning. We look for pitting on the stainless, lock-seam or crimp-joint separation, and insulation that has torn or pulled away from an insulated DuraFlex liner. If any of those conditions show up continuously over more than a short run, the liner’s integrity is compromised, and no amount of brushing fixes that. Short sections of damage can sometimes be addressed, but a liner with widespread corrosion or seam failure should be replaced. We’ll show you the camera footage and let you decide with your eyes, not just our word. Call (855) 382-3714 for a Level II inspection if the liner is over fifteen years old or you’ve had repeated draft problems.
It damages what’s around the liner more than the liner itself, but that still becomes a liner problem. Palos Heights winters freeze and thaw repeatedly, which spalls the brick and cracks the mortar crown on a 1950s-70s masonry chimney. When the crown cracks, water gets behind the cap, rusts the mesh, and works its way down against the DuraFlex top plate. The liner’s stainless alloy handles cold fine; what fails is the crown and cap assembly around it. That’s why we inspect the crown and top plate on every Palos Heights sweep. Leave that cracked crown alone, and you’ll be replacing a rusted cap within a few seasons.
Yes. Newer infill construction in Palos Heights brought in a wave of factory-built metal fireplaces, and many of them run DuraFlex flex liners as part of the venting system. The brushing routine and clearances are different on those than on a full masonry chimney, and we adjust accordingly. We inspect the liner, the termination cap, and the firebox condition. If the liner is the right size and the seams are intact, a cleaning is all it usually needs. If it’s undersized or showing corrosion, we’ll explain what that means for that specific fireplace.
Call us before you light anything. A nest packed against a DuraFlex liner or top plate is a fire hazard and a carbon monoxide risk, and a raccoon with kits won’t appreciate the eviction notice either way. We remove the animal and nesting material, reset or repair any insulation the animal chewed or pulled back, and install or replace the cap mesh so it doesn’t happen again. We’ve pulled squirrel nests and raccoon kits out of flues around Lake Katherine and the blocks near the forest preserves more times than we can count. Fall is when it happens. Call (855) 382-3714 and we’ll handle it before the first fire of the season.
