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 Near North Side, IL | Sandstone Chimney Sweep
We provide independent Near North Side Chimney Sweep DuraFlex cleaning and service across the Near North Side, from Old Town Triangle rowhouses to the greystone strips along Wells and Clark. What makes our DuraFlex work different here is simple: we know these liners are almost always running through shared party-wall chimneys, not freestanding stacks. That changes how we inspect, how we clean, and what we look for when something isn’t drafting right. Call (833) 589-7835 for a free estimate.
A quick note on who we are: DuraFlex sales & service is a big part of what we do, but Sandstone Chimney Sweep is an independent company. We’re not manufacturer-affiliated or authorized. That independence is the point. When we inspect your DuraFlex liner, we tell you what it actually needs, not what a warranty flowchart says to sell.
Why Near North Side Residents Choose Us for DuraFlex Service
Unlike companies offering DuraFlex in West Town, most chimney companies on the North Side can only run a brush through a flue. Far fewer have spent years pulling, inspecting, and repairing DuraFlex flexible stainless liners in the exact building types that define this neighborhood: attached greystones and rowhouses where the flue is the whole system and access is over shared roofs.
Norm Sobieski, our owner, grew up in Albany Park and learned the mechanical side of this trade through Truman College’s HVAC and building systems program. He’s been doing residential chimney work across Chicago’s northwest neighborhoods for years, and he’s known for being straight with people. No scare tactics, no invented problems. That’s the standard our DuraFlex inspections follow.
We stock genuine DuraFlex components here in the city, so most repairs don’t wait on a parts shipment. And because we’re the same team that inspects and repairs, there’s no gap between the guy who finds the problem and the guy who fixes it. We find it. We fix it.

Common DuraFlex Chimney Cleaning Problems We Solve in Near North Side
- Torn or degraded insulation wrap on liner sections. When a DuraFlex liner gets pulled through a tight, offset masonry flue in an old rowhouse, the insulation wrap takes abuse. We routinely find tears where the liner made a hard bend. The wrap is what protects against creosote contact and heat transfer, so a tear means the liner is under-protected exactly where buildup is worst.
- Corrosion and pitting at the top termination. Lake-effect winters aren’t gentle on exposed chimney tops. Freeze-thaw cycles with snow sitting on the crown mean moisture pools around the DuraFlex termination and connector joints. Rust and pitting at the cap area is one of the most common Near North Side failures we see, especially on greystones with older crowns.
- Disconnected or misaligned liner joints. Attached rowhouses settle. Over decades, shared party-wall chimneys shift slightly, and that movement can loosen DuraFlex connector joints. The result is draft loss and smoke spillage into the room, particularly on cold starts when the flue hasn’t warmed up yet.
- Crushed or obstructed liner sections from prior installs. We’ve pulled liners that were forced through bends in vintage flues, and the ridges tell the story. A partly crushed section traps creosote and cuts draft. This is a repair-or-replace call, and we’ll show you the camera footage so you can see it for yourself.
- Creosote buildup concentrated at offset bends. Near North Side flues are rarely straight. Offsets in old masonry mean creosote collects unevenly, and a brushed-only cleaning in a straight run misses what’s caked in the bend. Our Level 2 inspections catch this before it becomes a chimney fire risk.
DuraFlex Service in Near North Side: What Local Conditions Mean for Your Equipment
On the Near North Side, your DuraFlex liner is almost always inside a shared masonry chimney on an attached rowhouse or greystone, which is why Near North Side Dryer Vent Cleaning requires the same building-specific approach. That’s the defining fact here, and it changes everything about how we work. We can’t inspect just one fireplace. The flue is sharing wall space with a neighbor’s appliance connections, and draft problems in your unit are sometimes caused by what’s happening next door. Our inspection includes the party-wall flue and the neighboring connections, because that’s the only way to actually diagnose what’s happening in these buildings.
Rooftop access is the other half of the job. There’s no detached chimney to set a ladder against. We go up over a shared flat roof and a rebuilt parapet to reach the termination. On Old Town Triangle landmark buildings, the rules about what caps and repairs can look like add another layer. We’re familiar with those restrictions, and we work within them. The DuraFlex liner on a greystone isn’t like a liner in a suburban house. It’s a system inside a shared structure, reached from a roof you don’t own outright, and it needs a team that thinks that way from the start.
We were called to a greystone rowhouse in the Old Town Triangle a while back where a DuraFlex liner had been installed years earlier for a wood fireplace insert. The homeowner said smoke was backing into the room on cold starts. Up over the shared flat roof and parapet, our tech found the liner’s top termination loose and the insulation wrap torn where it had been pulled through an offset flue. We re-terminated the DuraFlex liner, replaced the damaged wrap section, cleared creosote from the trapped bend, and the draft came back strong. That’s the kind of job this neighborhood throws at you.
DuraFlex Models & Products We Service in Near North Side
We work on the full DuraFlex residential range that shows up in Near North Side buildings:
- DuraFlex Pro flexible stainless chimney liner kits – the standard for wood and gas appliance relining in older masonry flues.
- DuraFlex 316L stainless relining pipe – the alloy we recommend for wood-burning inserts and fireplaces where creosote acidity is a factor.
- DuraFlex insulation wrap and liner component kits – we replace torn wrap sections and damaged components routinely.
- DuraFlex stainless flexible relining for fireplace inserts – common in converted Near North Side rowhouses where a wood insert replaced an open hearth.
Our parts approach is straightforward: we use genuine DuraFlex components where a direct match matters. Top plates, caps, and coupling pieces come from DuraFlex. We’ll use a quality aftermarket part where it’s a sound equivalent, and we’ll tell you which is which. A scuffed liner section can often be repaired or re-terminated. A crushed or corroded-through run gets replaced, not patched.

AfterDuraFlex Service Pricing in Near North Side
Chimney cleaning on the Near North Side typically runs between $249 and $449 depending on liner length, access difficulty, and creosote stage. A Level 2 inspection, which we recommend when there’s been a change in performance or you’ve just bought the property, usually adds $150 to $300. If we’re doing a cap installation or replacement alongside, that’s generally $120 to $380 for DuraFlex-compatible terminations.
What drives the cost here is rooftop access over shared roofs and parapets, plus the condition of the liner itself. Every estimate starts with a conversation and a camera inspection so you can see what we see. Nothing is recommended without evidence you can look at yourself. Call (833) 589-7835 and we’ll give you an exact quote. Estimates are free, and we’ll tell you plainly if the liner can safely wait.

FAQs – DuraFlex Chimney Cleaning in Near North Side
Yes. Shared party-wall chimneys are the standard here, not the exception. We inspect the full flue including neighboring appliance connections, and we’ll let you know if draft problems are coming from your side, the shared stack itself, or the neighbor’s setup. Call (833) 589-7835 and we’ll walk you through what’s involved.
Cold starts in winter, especially with lake-effect winds, mean the flue hasn’t built enough heat to establish a strong draft. Loose terminations, torn insulation wrap, or creosote buildup in offset bends all make this worse. It’s a common Near North Side issue, and it’s usually fixable without replacing the liner. We can diagnose it with a camera inspection.
Yes, but the replacement needs to work with the landmark district’s appearance rules. We’ve handled cap changes on Old Town Triangle buildings and we source terminations that comply. The work itself is straightforward once we’re over the roof and parapet. Call (833) 589-7835 to discuss your building’s specific restrictions.
It depends on what the camera shows. Scuffs, partly degraded wrap sections, and loose terminations can usually be repaired. Crushed sections or corrosion that’s burned through the stainless mean replacement. We’ll show you footage of your liner and explain the call. We never recommend a replacement without visual evidence you can watch yourself.
Generally not. High-rise buildings don’t have traditional residential chimneys, so there’s no DuraFlex liner to service. Our Near North Side work concentrates in the older residential pockets: Old Town Triangle, the greystone strips along Wells and Clark, and the rowhouse blocks around Division, similar to how we handle DuraFlex in Near South Side properties.
