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 gas log sets with delayed ignition or sooting. The GL-550 and GL-750 series running on propane in Kennesaw homes often develop clogged pilot orifices from the fine clay dust that settles during our dry late-summer months. We pull the burner assembly, clean the orifice with the proper gauge bit, check gas pressure at the manifold, and replace the thermopile if millivolt readings drop below 325 mV. OEM pilots are available, but we’ve had better long-term results with Baso aftermarket kits on these units.
- Gelco wood-burning firebox refractory panel cracking. The Pre-fab 36 and 42 series installed in Kennesaw’s 1990s-era subdivisions (Chalker, Legacy Park) suffer thermal shock when homeowners burn green oak or overload the box. We measure crack width and depth per NFPA 211; anything over 1/8 inch or through to the metal wrapper means replacement. We source Gelco-spec refractory through our Haven buying network, or match with HeatShield factory panels when Gelco lead times stretch past three weeks.
- Gelco fireplace insert blower failure. The CB-36 and CB-42 insert blowers run hot and hard in Kennesaw’s shoulder seasons, when units cycle on and off daily. Bearing noise followed by seized rotation is the typical death spiral. We test amperage draw against the nameplate, check the snap-disc limit switch, and install either the OEM Fasco replacement or a cross-referenced Packard unit with the same CFM and static pressure rating. The aftermarket saves $80-$120; we write both options down and let you choose.
- Gelco damper corrosion in high-humidity flues. Kennesaw’s spring humidity, especially in homes shaded by mature oaks near Swift-Cantrell Park, rusts cast-iron throat dampers on Gelco wood-burning units within 8-12 years. The damper plate binds, then the frame cracks when forced. We inspect with a camera up the smoke chamber, measure the throat opening, and install a lock-top or Lyemance damper if the original frame is too far gone. Gelco never made a top-mount damper, so this is always an aftermarket solution.
- Gelco direct-vent termination screen blockage. The DV-42 and DV-55 horizontal terminations attract cottonwood seed, paper wasp nests, and the dense pollen that coats Kennesaw every April. Restricted intake air causes rollout or sooting; blocked exhaust triggers the safety switch. We pull the termination, measure CO in the firebox at startup, and install a proper termination guard if the original screen mesh has corroded open. We document intake and exhaust pressure readings before we leave.
Our Gelco Fireplace Services Process

- 1
Call and schedule. A live person answers, confirms your Gelco model if you know it, and books a two-hour arrival window. You’ll get a text when your tech is en route.
- 2
Camera-scan inspection. We run a chimney camera per NFPA 211 Level 2 standards, Clause 4 of the Haven Standard. For gas units, we also check manifold pressure and thermopile output. For wood-burning, we classify creosote and inspect liner condition.
- 3
Written findings and price. Corrine’s standing rule: we write it down before we ask you to decide anything. You get the camera stills, the scope of work, the parts list with OEM and aftermarket options where relevant, and the total price. No work starts until you approve in writing.
- 4
Repair or service with documented steps. Background-checked, uniformed techs perform the work. We photograph before, during, and after. Parts come from our Haven network - Gelco, DuraFlex, HeatShield, or matched equivalents.
- 5
Operational test and sign-off. Gas units: CO check at startup, spillage test, thermocouple dropout test. Wood-burning: draft measurement, smoke-puffer test. You receive the photo record, the written warranty, and the 365-Day Done Right Promise.
- 6
Archive and follow-up. Your record goes into our system - 38,000 and counting since 2009 - for reference on your next visit.

Why Kennesaw Homeowners Call Level Two Chimney Kennesaw for Gelco Work

We’re not a fireplace showroom pushing new units. We’re an independent Gelco service provider that fixes what you already own. Corrine Halstead and our techs know the difference between a GL-550 and a DV-55, and we stock the parts that fail most often so you’re not waiting three weeks for a back-ordered thermopile.
The Haven Standard governs everything: written price before work (Clause 1), verified and uniformed crews (Clause 2), arrive on schedule (Clause 3), documented photo record (Clause 4), and the 365-Day Done Right Promise stamped on every job. We’ve completed more than 38,000 chimney inspections and cleanings since 2009, every one with that same documentation.
When Gelco parts are scarce, we pull from our multi-brand network - DuraFlex for liners, HeatShield for refractory, Olympia Chimney for caps - and we tell you exactly what’s OEM and what’s equivalent. No surprises. No “trust us.” Just what we found, what it costs, and what you get in writing.
FAQs
No. As an independent Gelco service provider, our repairs don’t void manufacturer warranties, provided we use OEM or equivalent-spec parts and document the work. We keep parts receipts and installation photos in your record for any future warranty claim. Call (678) 535-2204 if you need documentation for a warranty dispute.
Common parts - thermopiles, blowers, refractory panels for the GL and CB series - are in our Kennesaw warehouse or available within 3-5 business days through our Haven buying network. Older DV-series direct-vent components can run 2-3 weeks if OEM. We always quote both OEM and quality aftermarket timelines so you can decide. Call (678) 535-2204 to check availability for your specific model.
Repair if the firebox liner is intact, the chassis isn’t rusted through, and repair costs stay under 40% of a comparable new insert. Replace if the unit is pre-1990, the heat exchanger is cracked, or you’ve already sunk $1,500 into repairs in the last three years. We give you the camera evidence either way - no pressure, just the numbers. Call (678) 535-2204 for an inspection and honest assessment.
Once per burning season if you use it as a primary heat source, or every two seasons for occasional fires. In Kennesaw, the oak and hickory most homeowners burn produces more creosote than the softwoods common up north. We find Class III glazed creosote in about one in four Kennesaw flues we inspect. An NFPA 211 Level 2 inspection with camera scan tells you where you stand. Call (678) 535-2204 to schedule.
Delayed ignition from dirty burners can crack the glass or damage the valve train. A failing thermopile can let gas seep after the flame goes out. These aren’t common, but they’re serious when they happen. The bigger risk is slow deterioration - a blower working harder, a heat exchanger corroding - that turns a $200 tune-up into an $800 repair. We write down what we find and flag what’s urgent versus what can wait. Call (678) 535-2204 for a free estimate.
