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 systems have been installed in Kennesaw homes for decades, particularly the stainless-steel liner kits and multi-flue caps that became popular during the 1980s and 1990s subdivision boom along Barrett Parkway and Stilesboro Road. Those units are now hitting 25-40 years of age. The combination of pine-heavy burning habits in this area and Kennesaw’s humid subtropical climate creates a specific wear pattern: acidic condensate from pine creosote pools in liner bottom joints during summer, while rust from failed chase covers attacks prefab metal flue chases from the outside. We’ve cleaned and repaired enough Marietta Gelco service systems nearby to recognize these failure modes on sight. We’re not affiliated with or authorized by Gelco - we’re an independent service provider who diagnoses Gelco components on their actual condition, not as a path to a manufacturer warranty upsell.
Why Trust Level Two Chimney Kennesaw for Your Gelco Chimney Cleaning?
Corrine Halstead, Owner at Level Two Chimney Kennesaw, completed her chimney and heating systems training at Apex Technical School in Manhattan before years of hands-on work on rooftops and inside fireboxes. She’s run her own operation long enough to know that Gelco’s 316L and 304 stainless liners, multi-flue caps, and top-sealing dampers each carry specific failure signatures that show up repeatedly in Kennesaw’s climate. Her crew has serviced homes throughout the area, including the older two-story colonials near Kennesaw Mountain where flue surprises turn up almost every season.
We write it down before we ask you to decide anything. That means a written price, written scope, and written warranty delivered before any work starts - Haven Standard Clause 1. Every Gelco service includes an NFPA 211 Level 2 camera-scan inspection with documented photo record - Haven Standard Clause 4, a practice we’ve maintained since 2009. Our technicians are background-checked, uniformed, and carry license information on every page and every job. You’ll get a text when your tech is en route, and you’ll see exactly what we found in your flue before we recommend any repair. Materials for Gelco work come through our Haven buying network from Gelco, DuraFlex, HeatShield, and other suppliers - sourced specifically to keep customer prices honest.
Common Gelco Chimney Cleaning Problems We Fix in Kennesaw

- Pinhole corrosion in Gelco 316L and 304 stainless liners. Pine creosote burns acidic. When it condenses at the bottom joint of a Gelco liner and sits through Kennesaw’s humid summers, it eats pinholes into the stainless. The first sign is often a smoky odor that worsens after rain. We camera-scan the full liner length, document the corrosion pattern, and recommend either localized repair or full liner replacement based on what the footage shows - never a guess.
- Spot-welded seam separation on Gelco multi-flue caps. The stainless and copper versions use spot welds that fatigue after 8-10 years of thermal cycling. Once a seam opens, rainwater runs directly into the flue, rusting the damper below and rotting framed chase enclosures. In Kennesaw’s Barrett Parkway subdivisions, we find original galvanized chase covers rusted through so completely that the cap is barely hanging on. We stock replacement Gelco-compatible multi-flue caps and can match the flue configuration on site.
- Rubber gasket failure in Gelco top-sealing dampers. The gasket hardens and cracks from UV exposure and temperature swings. The seal fails. Cold downdrafts pull creosote odor into the living room - a complaint we hear often from Kennesaw homeowners in October when the first cold front hits. We carry OEM Gelco damper gasket kits and can swap the seal without replacing the entire damper assembly if the frame is sound.
- Blower motor seizure in Gelco fireplace inserts. The surround gasket degrades over time, allowing soot infiltration into the blower housing. The motor seizes, the insert overheats, and firebox panels crack from thermal stress. We clean the blower housing, replace the gasket with OEM or equivalent material, and test airflow before we leave. If the firebox is already cracked, we tell you plainly - no patch job on a compromised heat exchanger.
- Water infiltration through deteriorating chase covers on prefab Gelco systems. Kennesaw’s high summer humidity accelerates rust on original galvanized covers from the 1980s-90s builds. Water pools in the firebox chase, rots surrounding framing, and corrodes the metal flue from the outside. Cap replacement is often the primary repair needed before a sweep is even warranted - we assess the full chase condition and document it with photos.

AfterGelco Parts & Our Repair-vs-Replace Approach
We use OEM Gelco replacement parts when they’re still in production - cap assemblies, damper gasket kits, blower components, and specified fasteners. For discontinued items, we source equivalent-gauge 316L stainless aftermarket components from our Haven network and tell you upfront if a full liner replacement makes more financial sense than chasing obsolete parts across multiple orders.
Our repair-vs-replace decision is straightforward: we show you the camera footage, explain the failure mechanism, and write down both options with prices. A Gelco multi-flue cap with one failed seam might warrant a cap replacement. A liner with pinhole corrosion at multiple joints and measurable wall thinning gets a replacement recommendation. We don’t profit from selling you something you don’t need - our 365-Day Done Right Promise covers the work we actually perform, and we’d rather earn the call-back on honesty than push an unnecessary replacement. Call (678) 535-2204 for a written estimate on your Gelco system.
Our Gelco Service Process - Step by Step

- 1
Diagnosis with camera inspection. We run a chimney camera the full length of your Gelco flue liner, inspect the cap, crown, and damper from the roof, and photograph the firebox and smoke chamber from below. For Gelco inserts, we remove the surround and inspect the blower housing and gasket condition. You get the photo record before we quote any work - Haven Standard Clause 4.
- 2
Written quote with scope and warranty. We deliver a written price, written scope, and written warranty before scheduling. No verbal estimates. For Gelco systems, we specify whether we’re using OEM or equivalent aftermarket parts and why.
- 3
Repair or installation. Our background-checked, uniformed technician arrives with a text notification, performs the scoped work, and documents each step. Creosote removal, cap replacement, and chimney waterproofing are completed to Gelco-compatible specifications.
- 4
Testing and final documentation. We test damper operation, verify draft with a manometer when indicated, and run a final camera pass to confirm liner integrity. You receive a completed photo record and warranty document before we leave.

FAQs - Gelco Chimney Cleaning Service in Kennesaw
No. We are an independent Gelco service provider, not affiliated with or authorized by Gelco. We diagnose and repair Gelco systems based on component condition and safe operation, not as part of any manufacturer warranty program. Our independence means we recommend what’s actually needed for your specific system.
We use OEM Gelco parts when they are still in production and available through our suppliers. For discontinued Gelco components, we source equivalent-gauge stainless aftermarket parts and document the substitution in your written scope. You’ll know exactly what you’re getting before work starts.
A standard Gelco chimney cleaning with Level 2 camera inspection takes 60-90 minutes. Cap replacement or damper gasket service adds 30-60 minutes. Full liner replacement in a Kennesaw prefab chase typically requires a half-day. We book by appointment and text when your tech is on the way - no waiting windows.
We service Gelco Stainless Steel Chimney Liner (316L and 304 alloys), Gelco Multi-Flue Caps, Gelco Top-Sealing Dampers, and Gelco wood-burning Fireplace Inserts. If you’re unsure which Gelco product is in your home, we identify it during the camera inspection and show you the markings.
Most original Gelco warranties on systems installed in Kennesaw’s 1980s-90s housing stock have expired based on age. For newer systems, warranty terms vary by product and installation date. We work with OEM-compatible practices that do not damage existing components, and we document our methods. If warranty coverage is a concern, we review your documentation and advise accordingly before proceeding.
Gelco chimney cleaning in Kennesaw typically runs $189-$289 for a standard sweep with Level 2 camera inspection and photo record. Gelco cap replacement ranges $340-$650 depending on size and material. Damper gasket replacement is usually $180-$280. Full liner replacement is quoted individually after camera inspection. Every price is written and agreed before work begins - call (678) 535-2204 for an exact quote; estimates are free.
Maybe. Pine creosote is more acidic than hardwood residue, and Kennesaw’s humidity accelerates corrosion at liner bottom joints where condensate pools. A camera inspection is the only way to know. We’ve seen Gelco 316L liners still sound at 20 years and 304 liners with pinhole corrosion at 12. We don’t guess - we camera-scan and show you the wall thickness and joint condition. Call (678) 535-2204 to book.
Often just the cap. If the chase cover framing is intact and the flue chase structure is sound, we replace the Gelco multi-flue cap with a matching or upgraded unit. If the original galvanized cover has rotted the surrounding framing - common in Kennesaw’s 1980s-90s prefab builds - we quote the full chase cover replacement and show you the rot in the photo record. No replacement happens without camera evidence you can see.
The rubber gasket has hardened and cracked. UV exposure and thermal cycling degrade the seal over 8-12 years. Once cracked, the damper can’t form a pressure seal, so cold downdrafts pull air past it - and often bring creosote odor with them. We replace the gasket with an OEM Gelco seal kit or equivalent, test the seal, and verify smooth damper operation before we leave.
We can sweep the flue above it, but we won’t clean the insert properly without removing the surround. Soot accumulates behind the surround and infiltrates the blower housing - that’s what seizes motors and cracks firebox panels. Our process removes the surround, cleans the full insert envelope, inspects the gasket, and documents blower condition. Anything less misses the actual problem.
We stock waterproofing treatments compatible with Gelco stainless liner terminations and masonry crown interfaces. For Kennesaw’s humid climate, we apply these at liner top and crown junctions to prevent the condensate pooling that accelerates pinhole corrosion. The treatment is included in our liner and cap replacement scopes when indicated, or quoted separately for preventive application.
