Gelco Chimney Cleaning in Logan Square, IL | Brightway Chimney Sweep
We provide independent Gelco chimney cleaning and component service across Logan Square, and the thing that separates our work here from a generic sweep is the multi-flue hunt. Most Logan Square chimneys are shared party-wall stacks serving two or three units, so we rarely clean a Gelco cap or damper without first figuring out which flue actually belongs to which apartment. If your fireplace, furnace, or water heater vents through Gelco components on a century-old greystone, call (833) 365-6591 and we’ll start with a straight assessment of what’s actually up there.
Brightway is an independent chimney and dryer vent specialist. We’re not authorized, sponsored, or warranty-endorsed by Gelco, and that’s the point: our recommendations come from what we’ve pulled off these roofs, not a brand script. Gelco sales & service is work we do regularly, but the honest diagnosis always comes first.
Why Logan Square Residents Choose Us for Gelco Service
Gelco Multi-Flue Steel Chimney Caps and Top-Mount Dampers are common on the boulevards and side streets around here, and Neil Borowski has spent the better part of three decades working on the same kind of two-flats and greystones he grew up near, and we now offer Gelco repair in West Town as well. That matters when a cap’s mounting legs have loosened in a freeze-thaw cycle or a damper has rusted shut over a humid Chicago summer. We’ve seen it enough times to know what we’re looking at before we even get on the ladder.
We carry Gelco OEM parts for direct-fit replacements on shared stacks, and we stock quality aftermarket stainless and refractory components when OEM parts are discontinued or priced wrong for an aging flue. Our service area covers Logan Square’s 60647 zip through and through, and we plan jobs around the reality that most of these chimneys have been modified, capped, or repurposed multiple times since the 1920s. You get straight answers about what your Gelco component needs and whether the real issue is the part or the unlined brick behind it. No pressure, no upsell script.

Common Gelco Chimney Cleaning Problems We Solve in Logan Square
- Seized Gelco top-mount dampers after humid summers. Chicago’s humid stretch from June through August lets rust build on the gasket and pivot of Gelco dampers, and by October they won’t seal. On a second-floor fireplace in a Logan Square two-flat, this shows up as a cold downdraft when the downstairs furnace kicks on. We free and reseat these when they’re serviceable, and replace the hardware when they’re not.
- Loose Gelco multi-flue caps on party-wall stacks. Freeze-thaw works the crown mortar loose around the mounting legs on shared chimneys, and suddenly a cap that covered two flues is letting snow and rain drop straight onto an unlined brick flue. We see this most on greystones off Logan Boulevard that haven’t been waterproofed in decades. The fix is reseating the cap and often repointing the crown before re-mounting.
- Cracked refractory panels and warped baffles in Gelco fireplace inserts. Run a Gelco insert hard in a workers’ cottage with an undersized flue that never drafted well to begin with, and the firebox takes the abuse. We replace cracked refractory panels and straighten or replace warped baffles, but we’ll also tell you plainly if the real problem is the flue size upstream of the insert.
- Lag anchors pulling free on Gelco stainless caps. A stainless cap is only as good as the brick it’s anchored into. On older greystone chimneys where spalling brick has softened the masonry, those lag anchors work loose season after season. We re-anchor into sound brick where possible, and we’ll flag the masonry repair before you buy another cap.
- Creosote smell through a capped chimney in summer. A Gelco cap keeps rain and animals out, but it doesn’t stop creosote that’s already built up inside the flue from off-gassing when humidity rises. If you smell creosote in a Logan Square apartment during July, the cap is doing its job; the flue behind it hasn’t been swept.
Gelco Service in Logan Square: What Local Conditions Mean for Your Equipment
Here’s the thing that’s true of Logan Square and not true of a lot of neighboring areas: because so many of these two- and three-flats share a single party-wall stack, a Gelco multi-flue cap installed for one unit’s fireplace often has to be lifted and re-set to service a neighbor’s furnace flue sitting inches away. Whoever installed it years ago didn’t always leave the mounting accessible to both owners. A routine sweep on the second-floor fireplace can turn into a coordination job with the downstairs neighbor before you can even inspect the cap. We’ve had jobs where the Gelco cap looked fine from the street but two of its four mounting legs were rusted through and the seal over the furnace flue had shifted, letting combustion gas pull back into the chimney cavity rather than venting clean. That’s not a failure any homeowner would spot from the ground. It’s the kind of thing that only shows up when someone actually gets on the roof and checks the cap against the flues it’s supposed to cover.
On a two-flat side street off Logan Boulevard, we were called for a routine sweep on a second-floor fireplace and found its Gelco top-mount damper rusted shut with a Gelco multi-flue cap covering both the fireplace flue and the first-floor furnace flue in the same party-wall stack. After coordinating with the downstairs owner, we freed and reseated the damper, replaced the cap’s corroded mounting legs, and confirmed on a Level 2 camera inspection which unlined flue actually served which unit. That hunt also turned up an abandoned coal flue with no cap at all, inches from the flue we’d been called to clean. A clean chimney doesn’t announce itself, and neither does the problem you avoided by having one.
Gelco Models & Products We Service in Logan Square
We service the Gelco product lines that show up most on Logan Square roofs: Multi-Flue Steel Chimney Caps, Top-Mount Dampers, Fireplace Inserts, and Single-Flue Stainless Caps. On a shared party-wall stack, we favor Gelco OEM caps and dampers when a direct replacement keeps the original fit across multiple flues. When OEM parts are discontinued or priced out of line for a flue that’s already marginal, we turn to quality aftermarket stainless and refractory components from the same professional supply lines we use across every job.
For faster turnaround in Logan Square, we keep common Gelco damper gaskets, pivot hardware, and cap mounting legs on the truck so a seized damper or loose cap doesn’t have to wait on a parts order. If your component needs a Level 2 inspection before we can tell you what’s actually wrong, we do that with a camera, not a guess.

AfterGelco Service Pricing in Logan Square
Gelco chimney cleaning and component service in Logan Square typically ranges from $189 to $370, depending on what’s involved. A standard sweep and inspection on a single flue runs toward the lower end. When we’re freeing a seized damper, replacing corroded mounting legs on a multi-flue cap, or running a Level 2 camera inspection to map a multi-unit stack, the job climbs because the labor and parts are more involved. Repair work on dampers, caps, and insert components lands between $225 and $650 in most cases. The biggest cost driver on these century-old two- and three-flats is flue access: when one cap covers multiple units, the work takes coordination and care that a single-flue chimney never requires.
A free estimate from us means we look at your stack, tell you what the Gelco component needs, and show you the condition of the flue behind it before you spend a dollar. Call (833) 365-6591 and we’ll schedule the assessment.

FAQs – Gelco Chimney Cleaning in Logan Square
No. We’re an independent chimney and dryer vent contractor that installs, services, and repairs Gelco caps, dampers, and insert components as part of our broader chimney work. We’re not authorized, sponsored, or warranty-endorsed by Gelco, which means our advice is based on what we’ve seen inside Logan Square chimneys, not a manufacturer script. Call (833) 365-6591 for an honest assessment.
We use Gelco OEM parts when a direct replacement keeps the original fit on a shared multi-flue stack. When OEM parts are discontinued or priced out of line, we use quality aftermarket stainless and refractory components from professional chimney supply brands like DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield. We’ll tell you which we’re using and why before we install it.
Most single-flue sweeps take 45 to 90 minutes. On a Logan Square two- or three-flat where one Gelco cap covers multiple flues, the job runs longer because we’re often coordinating with another unit and verifying which flue goes where before we clean. A full Level 2 inspection on a party-wall stack can take two hours or more, similar to the careful work we do on Gelco repair in Belmont Cragin. Call (833) 365-6591 and we’ll give you a realistic time window after we see your roof.
We service Gelco Multi-Flue Steel Chimney Caps, Top-Mount Dampers, Fireplace Inserts, and Single-Flue Stainless Caps. If you have a Gelco component on a Logan Square chimney that’s giving you trouble, call (833) 365-6591 and describe what you’re seeing. We’ll tell you whether it’s something we can fix on the spot.
Expect $189 to $370 for a typical Gelco chimney cleaning in Logan Square, with component repairs running $225 to $650 depending on what’s seized, rusted, or pulled loose. Party-wall stacks with multiple flues tend to cost more because the work takes longer and often involves a neighbor. Call (833) 365-6591 for a free estimate; we’ll quote you after we actually look at the chimney.
Because the cap isn’t the source of the smell. Creosote that’s built up inside the flue off-gasses when Chicago’s summer humidity rises, and a Gelco cap keeps rain and animals out but doesn’t remove what’s already coating the brick or liner. The answer is a sweep, not a better cap. Call (833) 365-6591 and we’ll clean the flue so the summer smell actually goes away.
