Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Gelco Chimney Cleaning in Evergreen Park, IL | Sandstone Chimney Sweep
We provide independent Gelco chimney cleaning and repair across Evergreen Park, IL, with a focus on the village’s 1940s – 60s brick ranches and Cape Cods. Most Gelco inserts we service here sit in exterior masonry chimneys with original clay-tile liners that have been taking on water for decades, so a basic cleaning often turns up damage that generic sweeps miss. That’s why our Gelco work always starts with a camera inspection before we touch the brush. Call (833) 589-7835 for a free estimate.
Why Evergreen Park Residents Choose Us for Gelco Service
Norm Sobieski grew up in Albany Park, learned building systems at Truman College, and spent years working residential chimneys across Chicago’s northwest neighborhoods before starting Sandstone. He’s pulled enough dead birds, rotted dampers, and cracked liners out of Gelco flues to know that the insert isn’t usually the problem. The chimney around it is.
We’re an independent shop, which means we’re not tied to a Gelco sales agenda. Our interest is whether your flue drafts, your liner holds, and your cap keeps water out. If your Gelco gas insert has a cracked firebox panel, we’ll tell you straight. If it just needs a gasket and a cleaning, we’ll do that instead. Evergreen Park homeowners tend to appreciate that honesty, especially on houses where the chimney has been quietly failing since the Eisenhower administration.
We also keep OEM-compatible Gelco parts in stock for the models we see most around 60805, which means we’re not waiting a week on a damper or gasket for your insert. Less standing around, more actual repair.

Common Gelco Chimney Cleaning Problems We Solve in Evergreen Park
- Cracked or spalling clay-tile liners behind Gelco inserts. The original tiles in Evergreen Park’s post-war chimneys were sized for coal furnaces, not modern gas inserts. Decades of flue-gas condensation and Chicago freeze-thaw have left most of them spalled or cracked. Your Gelco insert runs fine, but the liner behind it is quietly falling apart. Our Level 2 camera inspection shows you exactly what’s there before we call anything a cleaning.
- Missing or damaged rain caps on exterior masonry stacks. On a 1950s brick ranch, the chimney is usually on a side wall, open to the sky, with no cap at all. Rain goes straight down the flue, freezes, and pops tiles from the inside. We install properly fitted caps on every Gelco chimney we service in Evergreen Park, because without one, the cleaning won’t hold.
- Improperly sized or unlined flues serving Gelco gas inserts. Many Evergreen Park flues were never relined when the house converted from coal to oil to gas. A Gelco insert vented into an oversized, unlined clay flue drafts poorly, soots up the glass, and pushes combustion byproducts back into the living room. We size the liner to the insert, not the brick opening.
- Corroded dampers and firebox panels in Gelco units. Moisture sitting in a flue with no cap works its way down into the firebox. We regularly find Gelco dampers rusted through and firebox panels pitted beyond repair on Evergreen Park installations. If your glass doors fog up and won’t stay clean, water intrusion is the usual culprit.
- Birds, squirrels, and debris blocking Gelco venting. The exterior chimneys in Evergreen Park’s older blocks sit right at tree height, and uncapped flues become nesting spots. A blocked Gelco direct-vent system can cause draft reversal, pilot outages, and carbon monoxide alarms that go off for reasons you can’t see from the living room.
Gelco Service in Evergreen Park: What Local Conditions Mean for Your Equipment
Evergreen Park is built out. The housing stock is overwhelmingly post-WWII single-family homes, roughly 1945 to 1970, on tight 30- and 40-foot lots. Most of these houses have exterior masonry chimneys serving the furnace, water heater, and fireplace together. And those chimneys, in the vast majority of cases, still have their original clay-tile liners. Sixty to eighty years of Chicago-area freeze-thaw have done predictable damage. Tiles crack, spall, and fall into the flue. Mortar joints fail. Water gets in from the top because there’s no rain cap and sits there, freezing and thawing all winter.
For a Gelco insert owner, this matters more than most people realize. A gas insert doesn’t run hot like a wood fire, so creosote isn’t the main concern. The problem is that a gas insert doesn’t dry the flue out either. Moisture stays, and every winter the freeze-thaw cycle works on whatever clay tile is left. We’ve pulled chunks of tile out of Gelco flues off 95th Street that looked like they’d been through a rock tumbler. The glass on the insert was fine. The flue behind it was gone.
That’s why we won’t just brush a Gelco insert in Evergreen Park and call it done. The flue has to be evaluated, because on these houses, it’s the flue that fails first.
Gelco Models & Products We Service in Evergreen Park
We service all of Gelco’s major product lines in Evergreen Park: gas fireplace inserts, vented gas log sets, direct-vent gas fireplaces, and wood-burning fireplace inserts. We know the difference between a Gelco insert that needs a $40 gasket and one that needs a new firebox. When OEM Gelco parts are available, we source them. When they’re discontinued or priced beyond what the repair justifies, we use high-quality aftermarket equivalents and tell you which is which. If we can fix your Gelco insert with a new damper or gasket, that’s what we do. If the firebox is cracked or the liner has failed, we’ll recommend replacement and explain why with camera footage in hand. No mystery. No upsell.
We also install stainless steel liners sized to Gelco’s venting requirements, custom rain caps for multi-flue chimneys, and crown repairs that keep water out of the top of the stack.

AfterGelco Service Pricing in Evergreen Park
A standard Gelco chimney cleaning in Evergreen Park runs $180 to $340, depending on the condition of the flue and whether we’re doing a Level 2 camera inspection at the same time. If your chimney has a missing rain cap, cracked crown, or failing liner, those repairs are priced separately, and you’ll see the camera footage before you approve anything.
What drives cost here is what we find inside. A clean 1960s chimney with a cap and good liner is a fast job. A 1950s ranch with spalled tiles and a rusted damper takes longer and needs more work. We quote the sweep and inspection upfront, so there’s no sticker surprise. Call (833) 589-7835 for an exact quote; estimates are free, and we’ll tell you honestly whether a cleaning is all you need or if the flue has bigger problems.

FAQs – Gelco Chimney Cleaning in Evergreen Park
Yes, especially on a chimney that’s 60 to 80 years old and has never been relined. A Level 2 camera inspection shows us whether the clay tiles behind your Gelco insert are cracked, spalled, or blocked before we run a brush through. On Evergreen Park’s post-war homes, we find tile damage in a large percentage of flues that have never been inspected. Skipping the camera means cleaning a flue that may already be failing, and the same risk applies if you need Gelco repair in Ashburn. Call (833) 589-7835 to schedule an inspection, and we’ll show you the footage ourselves.
It’s one of the most common problems we document here. Without a rain cap, water goes straight down the flue, freezes through the winter, and cracks the clay tiles from the inside out. On the village’s many exterior side-wall chimneys, this has usually been happening for decades. We install properly fitted caps on essentially every uncapped Gelco chimney we service. If you’re not sure whether yours has one, call (833) 589-7835 and we’ll check it during the estimate.
We service both Gelco wood-burning inserts and Gelco gas inserts, including vented gas log sets and direct-vent units. Wood-burning Gelco inserts need more frequent sweeping because they produce creosote, while gas units still need the flue checked for moisture damage and venting blockages. The same inspection applies either way. If you’re in Evergreen Park—or need Gelco service in Merrionette Park—and not sure what your Gelco unit needs, call (833) 589-7835 and we’ll tell you.
That depends on how deep the rust goes. Surface rust on a damper or panel can often be cleaned and sealed if the underlying steel is still sound. Pitting that goes through the panel or a cracked firebox is a different situation; those usually need replacement because patching a firebox isn’t safe or reliable. The water that caused the rust usually came in through the top of the chimney, so we’ll also address the cap and crown. If you’re seeing rust in your Evergreen Park Gelco insert, call (833) 589-7835 and we’ll tell you honestly which path makes sense.
Yes. Many Evergreen Park homes have a single exterior chimney serving both the Gelco insert and the furnace or water heater, which means two or three flues side by side. A custom multi-flue cap covers the entire crown and keeps water out of all of them. Off-the-shelf round caps don’t work well on these older rectangular stacks. We measure, fabricate, and install caps that fit the actual chimney. Call (833) 589-7835 and we’ll check what your chimney needs.
