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.

AfterGelco Chimney Cap & Crown in Joliet: What to Know First
Level Two Chimney Joliet provides independent Gelco chimney cap and crown service across Joliet, from the historic bungalows near the Iron Works to the newer builds in Shorewood and Plainfield. Most Gelco cap replacements and crown repairs are completed in a single visit once we’ve run the camera and delivered your written price. We don’t start work until you’ve seen the photo record and signed off on a fixed scope, backed by our 365-Day Done Right Promise. If you own a Gelco multi-flue cap, stainless single-flue, or you’re dealing with crown seepage around a Gelco-mounted system, call (815) 620-5234. Corrine Halstead and our crew have handled Gelco products on thousands of Joliet-area chimneys since 2009.
How Gelco Products Fail - and How We Fix Them
- Multi-Flue Caps (Series 300/500): The expanded mesh on these units traps wind-blown debris from Joliet’s open prairie exposure, especially in spring when cottonwood and maple seed clusters pack the screening. Corrine’s crew sees this every May on homes west of Center Street. We remove the cap, clear the mesh with a non-destructive rotary brush, and if the frame has warped from heat cycling, we source a direct-fit replacement through our Haven buying network rather than forcing an ill-fitting generic.
- Stainless Single-Flue Caps (SC Series): The spot-welded lid seams split after 8-12 years of freeze-thaw in Joliet’s climate, where January lows hit -15°F and summer humidity pushes 90%. Water enters the seam, rusts the interior flange, and the cap loosens in high winds. We don’t caulk over this. We pull the cap, document the flue tile condition underneath, and install a replacement with a continuous-seam lid or upgrade to a bolt-down model if the flue shows erosion.
- Crown Wash Under Gelco Caps: Gelco caps mount tight to the crown surface, which hides crown deterioration until water is already migrating through the masonry. On a 1920s two-flat near Eastern Avenue last season, the cap looked fine from the ground. The camera found saturated brick above the firebox. We removed the Gelco unit, rebuilt the crown with a proper drip edge and slope, then reinstalled the cap with stainless spacers to break the cap-to-crown bond that traps moisture.
- Gelco Draft-Inducing Caps: The rotating turbine bearings seize in Joliet’s industrial particulate mix, especially downwind of the old steel mill corridors where fine metal dust settles. A seized turbine becomes a damper that traps smoke and CO. We test rotation during every Level 2 inspection, and when the bearing is shot, we replace with a Gelco OEM equivalent or, if the flue draft is marginal, recommend a static cap with a dedicated exhaust fan solution.
- Chimney Crown Coating Over Gelco Bases: Homeowners sometimes pay for a crown “seal” without removing the cap first. The coating bridges under the cap flange, looks complete, and fails in 18 months when water wicks behind the seal. Our process: cap off, crown media-blasted to bare concrete, two-part elastomeric applied to spec thickness, cure time documented, cap reinstalled with new fasteners. Clause 4 of the Haven Standard requires the photo record of each stage.
Our Gelco Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers at (815) 620-5234, 24 hours a day. We book your Level 2 inspection, confirm your Gelco model if you know it, and text you when your technician is en route.
- 2
Camera inspection first. We run the chimney camera before touching the cap. The flue liner, smoke chamber, and crown interior are documented. The photo doesn’t argue. It just shows you what’s there.
- 3
Cap removal and crown assessment. Your tech removes the Gelco unit, inspects the mounting flange, measures crown slope and integrity, and checks for spalling or delamination hidden underneath.
- 4
Written price, written scope. You receive a fixed price for parts and labor, a description of OEM versus quality aftermarket options, and the warranty terms. No work starts until you approve in writing. Haven Standard Clause 1.
- 5
Repair or replacement. We complete the cap installation, crown rebuild, or coating application using materials sourced through our Haven network. Multi-flue caps are leveled and storm-strapped. Single-flue caps are bolted or clamped to spec.
- 6
Post-work test and documentation. We run a final camera pass, verify draft and cap clearance, and deliver your photo record and warranty documentation. The 365-Day Done Right Promise begins at signature.

Why Joliet Homeowners Call Level Two Chimney Joliet for Gelco Work
We’ve inspected and serviced more than 38,000 chimneys since 2009, and Gelco products show up consistently in Joliet’s 1990s-2010s housing stock, especially the split-levels and raised ranches around the Caton Farm Road corridor. Our techs know the Gelco catalog well enough to spot when a cap labeled “universal” won’t clear a raised flue tile or when a multi-flue frame needs field modification for a chimney with an offset.
Because we source through the Haven buying network across multiple brands, we’re not locked into a single supplier. If your Gelco unit is discontinued or a DuraFlex or HeatShield equivalent offers better value for your specific flue configuration, we’ll show you both options with prices and let the documentation guide the choice. Background-checked, uniformed technicians. License number on every page. Written price before work starts. Photo record after. That’s Clause 4, and it’s been our practice since before it had a name.
FAQs
No. As an independent Gelco service provider, we use OEM-spec or equivalent parts and document our work, which satisfies warranty requirements for maintenance-related coverage. We are not affiliated with or authorized by Gelco, and we never represent ourselves as such. If your cap is under original warranty, we’ll note the install date and series number in your documentation so any future claim is supported. Call (815) 620-5234 if you need help locating your original purchase record.
Replacement is necessary when the lid seam is split, the mesh is torn at the frame weld, or the base flange has rusted through. Repair is sometimes possible for loose fasteners, minor screen clogging, or a stuck draft turbine. We make this determination only after removal and inspection, and we show you the photos before quoting either option. Free estimates - call (815) 620-5234.
Many Gelco series from the 2000s and 2010s remain available through our Haven network suppliers, though some finishes and custom sizes have been discontinued. When OEM is unavailable, we source dimensionally matched aftermarket caps from Olympia Chimney or Famco that maintain proper clearance and storm resistance. We never install a “close enough” fit. Your written scope specifies the exact part number and source before work begins.
Most cap replacements are completed in 2-3 hours. Crown rebuilds or coating applications typically run 4-6 hours including cure time for surface prep materials. We schedule with enough margin that your technician isn’t rushing to the next job, and we don’t leave until the camera confirms clear flue passage and the cap is secure. Call (815) 620-5234 to book.
A failed cap admits water, debris, and animals directly to your flue. In Joliet’s freeze-thaw climate, that water cracks flue tiles, erodes mortar joints, and can saturate adjacent framing. Carbon monoxide risk rises when flue gases leak through cracked tile into the chimney cavity. The repair cost typically doubles or triples within two to three seasons of neglect. We document the progression with photos so you can decide with real information, not pressure. Call (815) 620-5234 for a free inspection and written estimate.
