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.

How Gelco Products Fail - and How We Fix Them
- Gelco Multi-Flue Chimney Caps (Model M-8, M-12 series) - The 304 stainless mesh on these caps degrades faster than expected in Joliet’s freeze-thaw cycle, especially on homes west of the Des Plaines River where wind-driven rain accelerates corrosion at the corners. We see the mesh separate from the frame while the lid itself is still sound. Our fix: we source replacement mesh panels through Haven’s buying network and reattach with stainless rivets rather than spot-welds, which lets us preserve the original frame and save you the cost of a full cap replacement.
- Gelco Single-Flue Caps with Leg Kits (L- series) - The adjustable leg brackets loosen over time on Joliet’s older masonry, particularly the soft brick common in pre-1950 bungalows near the Iron Works Historic Site. The cap tilts, creating a gap that funnels water directly onto the crown. We reset legs with stainless wedge anchors rated for the specific compressive strength of your brick, then seal the penetration with a flexible flashing compound that moves with the masonry.
- Gelco Chimney Pots (Victorian and Craftsman lines) - These cast-concrete pots spall from the inside out when flue gases condense against cold surfaces during Joliet’s January temperature swings. The surface looks sound until a chunk falls. We remove the pot, assess the flue tile beneath, and either reinstall with a proper flue liner extension or recommend a HeatShield cerfractory seal if the flue itself has shifted.
- Gelco Lyemance and Lock-Top Dampers - The silicone rubber gasket on these top-sealing dampers hardens after 8-12 seasons of Joliet’s summer humidity followed by sub-zero dry cold. The damper won’t seal fully, and you lose conditioned air up the flue. We measure gasket groove dimensions precisely - Gelco changed the groove width between 2012 and 2018 production runs - and install either OEM replacement gaskets or a machined aftermarket equivalent that matches your specific casting date.
- Gelco Pre-Fab Chase Covers (galvanized and aluminum) - The drip edge on these covers is stamped too shallow for the volume of water Joliet’s spring storms deliver. Water backs up and rots the chase framing. We fabricate a replacement cover with a deeper 1.5-inch drip edge and cross-break the pan for positive drainage, using thicker aluminum stock than Gelco’s original spec. The photo doesn’t argue. It just shows you what’s there.
Our Gelco Chimney Repair Process
- 1
Call and schedule. A live person answers, 24/7. We book your NFPA 211 Level 2 camera inspection - not a flashlight peek - and text you when your technician is en route.
- 2
Camera-scan diagnosis. We run a high-resolution camera down the flue and photograph the exterior: crown, brick, mortar joints, flashing, cap. Corrine Halstead reviews the footage with you on-site before discussing price.
- 3
Written scope and price. You get a written price, written scope, and written warranty before anyone picks up a trowel. Haven Standard Clause 1: have it in writing. No exceptions.
- 4
Parts decision. We confirm whether your repair needs OEM Gelco components or if a quality aftermarket part from our DuraFlex, HeatShield, or Olympia Chimney supply lines meets the spec without compromising function. We explain the trade-off and let you decide.
- 5
Repair and test. We complete the work, run a final camera pass to verify the repair, and test draft and spillage with a manometer where applicable.
- 6
Documentation and follow-up. You receive your photo record, written warranty, and our 365-Day Done Right Promise. Haven Standard Clause 4 requires the documented record - we’ve done this on every job since 2009.

Why Joliet Homeowners Call Level Two Chimney Joliet for Gelco Work
We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a significant share of those in Joliet have Gelco caps, dampers, or chase covers installed by original builders or previous owners. Our technicians are background-checked, uniformed, and assigned by name - you’ll know who’s coming. We carry DuraFlex liner materials, HeatShield cerfractory sealant, and Olympia Chimney components alongside Gelco-sourced parts, so we’re never stuck waiting on a single supplier. Every job is independently owned and operated under the Haven Standard, not a franchise model. The 365-Day Done Right Promise means if our repair fails, we make it right. And Clause 4 of the Haven Standard requires that photo record on every visit - not because regulators asked for it, but because we started doing it in 2009 and it became the standard others followed.
FAQs
No - provided the repair uses Gelco-compatible parts and practices. As an independent Gelco service provider, we are not affiliated with or authorized by Gelco, but we follow manufacturer torque specs, gasket dimensions, and material grades so that any remaining warranty coverage stays intact. We document the parts used and the work performed in your written record. Call (815) 620-5234 if you need us to review your warranty terms before scheduling.
Most Gelco repairs - cap mesh replacement, damper gasket swaps, leg resets - are completed in two to four hours on site. Chase cover replacements and chimney pot work usually take a full day. Partial rebuilds run two to three days depending on weather and cure times for mortar. We give you a firm schedule in your written scope, not a window. Call (815) 620-5234 for availability.
Repair is almost always the right call when the flue liner is sound and the masonry damage is localized. We replace only when the camera shows cracked flue tile, significant structural settlement, or when three or more Gelco components have failed from the same underlying cause - usually water intrusion that has compromised the chase or crown. You’ll see the camera footage and we’ll explain which category you’re in before any price is discussed. Call (815) 620-5234 for a free inspection.
Yes - common Gelco caps, dampers, and gaskets are available through our Haven buying network within two to three business days. For discontinued lines or custom chase covers, we fabricate replacements in-house or source from Olympia Chimney and Famco with equivalent or improved specifications. We never leave a chimney open while waiting on parts; if there’s a delay, we install a temporary cap at no extra charge. Call (815) 620-5234 to confirm parts availability for your specific model.
Spalling brick lets water into the wall cavity, which rots framing and rusts the firebox. A failed damper gasket wastes energy year-round and can allow backdrafting of combustion gases. A separated cap mesh invites birds, squirrels, and chimney fires from nesting material. The risks escalate in Joliet’s climate because freeze-thaw cycles accelerate masonry damage once water has entry. We don’t scare-sell - we show you the camera footage and explain your timeline. Some repairs can wait a season; others shouldn’t. Call (815) 620-5234 and we’ll tell you which yours is.
