Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
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 Arlington Heights, IL | Emberly Chimney Cleaners Arlington Heights
Independent Gelco chimney cleaning and repair in Arlington Heights runs $180-$340 for a standard sweep with Level 2 camera inspection, and most appointments are booked within a week during off-peak months. What separates our Gelco work here from generic sweep service is the orphaned water heater - a condition we find in roughly half the ranch and split-level chimneys we inspect in Arlington Heights’s 1950s-1970s neighborhoods, where an original oil furnace was swapped for high-efficiency gas and the water heater was left venting alone into an oversized flue. We stock Gelco-compatible caps, storm collars, and liner sections for same-visit resolution when possible. Call (331) 202-2419 for a written estimate before any work starts.
Why Arlington Heights Residents Choose Us for Gelco Service
Corrine Halstead learned the trade at Apex Technical School in Manhattan before building crews across the northwest suburbs, and she’s run sweeps and camera inspections in Arlington Heights for years - including plenty of calls near the shops and older colonials along Campbell Street. Her rule, and ours: the camera doesn’t guess. Neither do we.
We are not affiliated with or authorized by Gelco. We are an independent service provider who stocks and fits Gelco-compatible parts through Haven’s buying network, sourced alongside DuraFlex, HeatShield, and Olympia Chimney materials specifically to keep customer prices honest. Every Arlington Heights job starts with an NFPA 211 Level 2 inspection - camera down the flue, documented photo record, written scope and price before any work begins. Clause 4 of the Haven Standard requires that photo record on every job; we’ve done it since 2009.
Our technicians are background-checked, uniformed, and assigned by name. You get a text when they’re on the way, and a written warranty when they leave. The 365-Day Done Right Promise applies to every our Gelco services repair and cleaning we perform in Arlington Heights.
Common Gelco Chimney Cleaning Problems We Solve in Arlington Heights

- Orphaned water heater venting into oversized Gelco or clay-tile flues. After the original oil furnace was replaced with high-efficiency gas, the water heater was often left alone on a flue built for a much larger appliance. Flue gases cool too fast, condense, and produce the white efflorescence streaks and faint sulfur odor we regularly spot on ranch homes near Campbell Street and the historic downtown grid. The inner wall of Gelco B-vent or adjacent clay tile degrades from the acidic moisture.
- Freeze-thaw cycling degrading Gelco Type B vent joints. Arlington Heights sits in the upper Midwest continental climate zone, where winter temperatures cross 32°F dozens of times per season. That repeated expansion and contraction cracks the outer galvanized wall and loosens the gasketed joints of Gelco Type B vent on exterior chases, especially on the long roof runs typical of postwar ranches and split-levels.
- Creosote glazing in Gelco Model A prefab fireboxes. When dampers are left partially closed and the unit is run hard during cold snaps - common in Arlington Heights, where northwest winds off the open suburban plain accelerate chimney heat loss - Class III creosote bakes onto the firebox walls. This glazed layer is nearly impossible to remove with standard brushing and requires mechanical treatment.
- Spalling brick and crumbling mortar at Gelco chimney terminations. The same freeze-thaw cycle that attacks joints also destroys the masonry surrounding the chase top. Moisture enters through cracked mortar, rusts the top sections of Gelco pipe, and stains the exterior brick. We see this pattern repeatedly on original 1960s chimneys that have reached or exceeded their engineered service life.
- Incorrectly sized replacement caps and storm collars. Generic hardware-store caps don’t seal properly on Gelco factory-built terminations, letting water run down between the cap and the flue wall. We fit Gelco-compatible OEM-spec or code-listed aftermarket caps sized to the exact vent diameter, installed with proper storm collar overlap.

AfterGelco Service in Arlington Heights: What Local Conditions Mean for Your Equipment
Arlington Heights developed explosively in the 1950s through 1970s, leaving the village dominated by ranch homes and split-levels whose original masonry chimneys - built for oil-fired furnaces - are now 50-70 years old and largely unmodified. When those furnaces were swapped out for high-efficiency gas systems over the decades, the water heater was typically left “orphaned” on an oversized clay-tile flue, creating chronic condensation, accelerated liner deterioration, and creosote buildup that is far more common here than in the newer-built suburbs to the northwest like Buffalo Grove or Algonquin. For Gelco owners, this means the appliance lineup matters as much as the firebox condition. On a raised ranch off the historic downtown grid, we pulled a heavily glazed Gelco Model A firebox and found the flue was also serving an orphaned water heater, which had left efflorescence streaking the exterior brick and a faint sulfur odor inside. After a Level 2 inspection confirmed cracked clay tile alongside the Gelco sections, we removed the glazed creosote, installed a correctly sized Gelco-compatible liner and a multi-flue cap, and waterproofed the crown and brick to stop the freeze-thaw spalling. That sequence - inspect the whole venting system, not just the visible firebox - is standard on every Arlington Heights call because of this housing stock.
Gelco Models & Products We Service in Arlington Heights

We service and repair the full range of Gelco factory-built venting systems found in Arlington Heights’s postwar housing stock: Gelco Type B gas vent in round and oval double-wall configurations; Gelco Model A prefab wood-burning fireplace and chimney systems; Gelco triple-wall factory-built chimney sections; and Gelco direct-vent and flexible liner kits. Our Arlington Heights van stocks Gelco-compatible OEM-spec caps, storm collars, and vent sections where available, plus code-listed aftermarket equivalents where Gelco OEM has been discontinued. We do not use generic hardware-store substitutes. If a Gelco B-vent or prefab firebox is structurally compromised - cracked inner wall, rust-through at joints, or firebox panel deformation - honest replacement is usually the safer call than repeated patching. We source replacement materials through Haven’s buying network to keep pricing honest, and every option is quoted in writing with a documented photo record before work begins.

FAQs - Gelco Chimney Cleaning in Arlington Heights
Yes. We service Gelco Model A prefab fireplaces, Type B gas vents, triple-wall chimney sections, and direct-vent liner kits across Arlington Heights. We are an independent service provider, not affiliated with or authorized by Gelco, but we stock Gelco-compatible parts and have completed thousands of inspections and cleanings on these systems in Cook County’s northwest suburbs. Call (331) 202-2419 to schedule.
That faint sulfur odor almost always means an orphaned water heater is venting into an oversized flue, a pattern we find constantly in Arlington Heights’s 1950s-1970s ranch and split-level neighborhoods. The water heater’s small volume of flue gas cools too quickly in the large flue, condenses, and produces acidic moisture that degrades clay tile and Gelco B-vent inner walls while releasing that characteristic smell. A Level 2 inspection confirms the appliance lineup and flue condition. Call (331) 202-2419 for an exact quote; estimates are free.
Sometimes. Gelco Model A fireboxes can accept certain listed inserts if the chimney system passes a full Level 2 inspection and the manufacturer’s conversion criteria are met. We do not perform conversions on structurally compromised fireboxes or where the flue liner shows degradation - the documented photo record from our inspection shows exactly why. If conversion is viable, we quote the insert, liner adapter, and venting in writing before ordering any materials.
NFPA 211 recommends annual inspection for all chimney systems, and Arlington Heights’s freeze-thaw climate plus the orphaned-water-heater condition in our older housing stock makes that schedule especially prudent for Gelco systems. Homes with frequent fireplace use or visible efflorescence, spalling, or odor should not wait. Call (331) 202-2419 to book; estimates are free.
Yes, when the spalling is caught before structural failure. Waterproofing with a vapor-permeable masonry sealer stops the freeze-thaw cycle from driving water into brick pores and popping off the face - the spalling pattern we see on original 1960s chimneys throughout Arlington Heights. Waterproofing does not repair already-compromised mortar or cracked flue tile; those require separate repair. We include crown and chase-top sealing in our waterproofing scope, and we document before-and-after condition with photos. Call (331) 202-2419 for an exact quote; estimates are free.
