Why Oak Brook Residents Choose Us for Gelco Service
Most of the Gelco fireplaces and chimneys we work on in Oak Brook are original to homes built thirty to sixty years ago, which means the equipment has outlived at least one round of suburban remodeling. We know these systems because we’ve torn down, swept, and rebuilt Gelco masonry and prefab units across Chicago’s western suburbs for years. Norm Bledsoe, our owner, spent nearly two decades working chimneys in this area, and he built the company around one rule: a clean flue is the whole job, everything else is just finding out why it isn’t. That mindset means we don’t rush a sweep and hand you a receipt. We document what we find, explain what it means for your house, and use OEM Gelco caps, dampers, and firebox components wherever they’re still available. When OEM parts are discontinued, we tell you that plainly and install a quality aftermarket alternative we’d put on our own chimney. Oak Brook homeowners tend to be precise about their homes, and we respect that.

Common Gelco Chimney Cleaning Problems We Solve in Oak Brook
- Glazed creosote on smoke chambers and flue tiles. Oak Brook winters mean long burns and cold starts on big masonry fireplaces. When a fire smolders overnight and the flue stays below condensing temperature, creosote hardens into a third-degree glaze that won’t brush off. We deal with this constantly on Gelco units in 1960s and 1970s estate homes, and it requires mechanical removal and sometimes chemical treatment before a clean sweep is even possible.
- Chimney-top moisture intrusion and freeze spalling. Sustained subfreezing spells in the Chicago area drive the classic failure on Oak Brook’s original chimneys: a hairline crown crack takes on water, the upper flue tiles saturate, and the freeze-thaw cycle spalls brick faces and mortar joints. We find this on Gelco masonry chimneys with shared crowns and stacked clay tiles more than almost any other pattern.
- Cracked, offset, or spalled clay tile liners. These Gelco systems are now 30 to 60 years old. The original clay liners were never meant to last forever, and on custom homes where fireplaces saw regular use through the 1980s and 1990s, we routinely photograph cracked joints and offset tiles during Level 2 inspections. Homeowners are almost always surprised because the fireplace still drafts fine, but the liner is compromised.
- Raccoon and squirrel nesting debris. Oak Brook’s wooded estate lots near the Salt Creek corridor and forest preserves produce a steady spring stream of calls described as “scratching in the chimney.” Capped-off or rarely-used Gelco flues become nesting sites. By the time the scratching starts, the flue is often half-packed with twigs, leaves, and animal material that blocks draft and creates a fire hazard.
- Pitted fireboxes and rusted dampers on gas-converted Gelco units. Many Oak Brook homes converted wood-burning Gelco fireplaces to gas inserts during 1980s and 1990s remodels. The original firebox and damper were left in place, and now moisture and condensation collect behind the surround, rusting the damper and pitting firebox panels. A sweep alone doesn’t address it; the conversion needs inspection and often component replacement.
Gelco Service in Oak Brook: What Local Conditions Mean for Your Equipment
Oak Brook is a small, affluent, heavily commercial village built around Oakbrook Center and corporate campuses, and its housing stock is almost entirely large custom and estate homes from the 1960s through the 1990s on wooded lots. That changes how Clarendon Hills Gelco service and similar western suburb work plays out here. These aren’t rowhouse flues or tract-home chimneys where a sweep takes forty minutes and the access is predictable. Many Oak Brook homes have multiple fireplaces, masonry chimneys with clay tile liners, and prefab or insert installs added during remodels, so a single property can mix three different Gelco system types. Mature oak and hardwood lots mean heavy leaf and animal debris loads every fall and spring. Original liners now 30 to 60 years old are the standard inspection finding, not the exception. When we show up to a home off Midwest Road or near the Salt Creek corridor, we expect big multi-flue chimneys, expensive fireplaces that haven’t been opened in years, and homeowners who want documentation, not a quick brush and a wave goodbye. That’s the job, and it’s the reason we carry camera inspection equipment, wildlife removal tools, and OEM-compatible parts on every Oak Brook call.

AfterGelco Service Pricing in Oak Brook
Chimney sweep and inspection pricing in Oak Brook typically runs $180 to $340 for a standard Gelco fireplace, depending on flue condition, accessibility, and whether animal debris needs removal. A Level 2 camera inspection adds cost but is often warranted on these older systems, especially before a home sale or after buying an estate property. Waterproofing, crown repair, damper replacement, and liner work are quoted separately after we show you the photos. What drives cost on Oak Brook jobs specifically is the multi-flue layout and the condition of 30 to 60 year old masonry. We don’t quote over the phone without seeing the chimney, and we don’t recommend work without camera evidence you can look at yourself. Call (855) 382-3714 and we’ll come out, inspect what you’ve got, and give you a straight number.

FAQs – Gelco Chimney Cleaning in Oak Brook
Yes. We service both Gelco masonry fireplaces with clay tile liners and Gelco factory-built and prefab fireplaces, including the 1960s through 1990s systems common in Oak Brook’s estate neighborhoods. Many of these homes have multiple fireplaces on the same chimney or split-level chase configurations, and we inspect each flue individually. Call (855) 382-3714 and we’ll tell you exactly what type of system you’re working with and what it needs.
A Gelco fireplace that starts hard on cold mornings in Oak Brook usually has a draft problem caused by a cold flue, a partially blocked flue from nesting debris or glazed creosote, or a damper that isn’t opening fully. On a frosty morning with a cold masonry chimney, the air inside the flue is dense and sinking, so you get smoke pushing back into the room until the flue warms up. If it happens regularly, it’s not just weather, it’s a restriction or a mechanical issue. We diagnose it with a Level 2 camera inspection and correct it rather than telling you to burn hotter fires.
A Level 1 inspection is a visual check of the accessible portions of the fireplace, flue, and exterior chimney, which we perform with every sweep. A Level 2 inspection adds camera scanning of the entire flue interior, the smoke chamber, and the chase or multi-flue layout, which is how we find cracked or spalled clay tiles, hidden animal debris, and failed crown or flashing conditions that don’t show up on the surface. For Oak Brook homes with original 1960s to 1990s Gelco liners, we recommend a Level 2 every time the home changes ownership and whenever a sweep turns up anything unusual.
If you’re hearing scratching in a chimney in Oak Brook, especially in spring, that’s an animal call first and a cleaning call second. The wooded lots near the Salt Creek corridor and forest preserves mean raccoons, squirrels, and birds routinely nest in capped-off or rarely-used flues. We arrive equipped for wildlife removal and a full Level 2 look, because animals often damage liners and crowns in the process of getting in. Call (855) 382-3714 and we’ll tell you if you’re dealing with a nest or a structural issue, or both.
Yes, chimney waterproofing slows the freeze-thaw cycle that causes spalling brick and crown cracks on Oak Brook’s exterior masonry. But waterproofing alone doesn’t fix a liner that’s already cracked, and it doesn’t repair a crown that’s already failed. On a Gelco chimney with spalled brick, the proper repair is to fix the crown, replace any cracked upper flue tiles, and then apply a breathable masonry water repellent so moisture can’t soak into the structure through winter. We’ll show you the damage before recommending anything.
