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 Cleaning in Baltimore, CA | Flint Chimney Sweep
We’re an independent chimney service company that provides Chimney Sweep - Baltimore, inspects, and repairs Gelco fireplaces throughout Baltimore. A standard Gelco chimney cleaning here runs $189 – $329, and the price is in writing before we touch the fireplace. What makes our work different is that we service Gelco units in Baltimore’s rowhouse stock, where shared flues and hundred-year-old masonry create failure modes a generic sweep misses. Call (830) 251-4560 for a free estimate.
Why Baltimore Residents Choose Us for Gelco Service
We’ve worked on Gelco GV-Series gas fireplaces, G Series wood-burning units, and Insert Series appliances in Baltimore homes for years. That matters because Gelco fireboxes and venting behave differently from other brands, and a technician who has never pulled a Gelco damper assembly apart won’t know what to look for. Hank Delano, our owner, learned chimney work through the building maintenance and construction technology program at Los Angeles Trade-Technical College and put in years of hands-on field experience before founding Flint Chimney Sweep. He grew up in Eagle Rock and has spent his working life within a few miles of the San Gabriel foothills, so he reads firebox and flue conditions the way someone reads a neighborhood they’ve walked for decades. As Gelco sales & service specialists, we carry the tooling and the parts knowledge to handle these units correctly the first time.
Common Gelco Chimney Cleaning Problems We Solve in Baltimore
- Rust-jacked fireboxes from Baltimore humidity. Gelco’s painted steel fireboxes absorb moisture during humid Baltimore summers and freeze-thaw winters. The steel oxidizes, expands, and pushes against surrounding masonry. We see this most often in neighborhoods like Federal Hill and Canton, where older rowhouses trap moisture against the chimney chase.
- Direct-vent termination cap corrosion and clogging. Gelco direct-vent gas units vent horizontally through exterior walls. Baltimore’s salt air, ice, and nesting birds corrode and clog those small caps. When a termination cap clogs, exhaust recirculates into the home and the unit shuts down mid-cycle. We replace these caps regularly.
- Seized and warped dampers after humid off-seasons. Gelco wood-burning dampers are steel, and steel that sits in a damp flue all summer seizes. By October, the damper either won’t open or won’t seal. Baltimore owners call us every fall with this exact problem.
- Cracked refractory panels from thermal cycling. Older Gelco factory-built units use refractory panels inside the firebox. Baltimore’s temperature swings – hot fires in January, cold damp masonry in March – stress those panels until they crack. Cracked panels can expose combustible framing. This is a repair, not a cleaning issue, and it needs to be caught during inspection.
- Glazed creosote from damp wood. Baltimore gets wet. Firewood stored in rowhouse backyards or basement bulkheads absorbs moisture. Wet burns create dense, glazed creosote that a standard brush won’t remove. We use mechanical rotary tools for this, and Baltimore has plenty of it.
Gelco Service in Baltimore: What Local Conditions Mean for Your Equipment
The reality that shapes Gelco service in Baltimore more than anything else is the shared-flue rowhouse construction. Baltimore’s rowhouse stock, much of it built between 1880 and 1930, often has chimneys that serve two or more adjoining homes through a common stack. A Gelco fireplace in one unit can push smoke, odor, or carbon monoxide toward a neighbor through a compromised common flue, even when the owner’s own firebox looks fine. Our techs assess the entire stack and the separation between flues, not just the unit in front of them. In Fells Point and Mount Vernon, where rowhouses sit wall-to-wall, this is the difference between a cleaning that solves the problem and one that doesn’t. We’ve also worked on Gelco units in Baltimore service area homes outside the rowhouse core, where the issues lean more toward cap corrosion and dampers than shared stacks.
Gelco Models & Products We Service in Baltimore
We service the full Gelco lineup that shows up in Baltimore homes: GV-Series vented gas fireplaces, G Series factory-built wood-burning fireplaces, Insert Series wood and gas inserts, and Gelco direct-vent and B-vent gas heating appliances. For wear items, we carry aftermarket parts that meet or exceed Gelco OEM specifications – damper assemblies, termination caps, refractory panels, gaskets. If a customer requests OEM parts or a specific fitment demands it, we use Gelco OEM. This keeps turnaround fast, because we’re not waiting on a manufacturer shipment for a part we already have on the truck. We give straight repair-versus-replace guidance based on the unit’s age and the cost of the fix. If a 22-year-old Gelco needs a firebox rebuild that costs more than the unit is worth, we’ll say that plainly.

FAQs – Gelco Chimney Cleaning in Baltimore
No. Chimney cleaning and inspection work does not require manufacturer authorization, and we are an independent company not affiliated with, authorized by, or endorsed by Gelco. What matters is that the technician knows Gelco’s specific venting and firebox design. Ours do. Call (830) 251-4560 if you want to talk through what your unit needs.
Every 25 to 30 burns, or once per burning season at minimum. Baltimore’s damp climate means firewood picks up moisture, and moisture creates creosote faster. If you’re burning most weekends from November through March, you need a sweep before the season and a check mid-season. Call (830) 251-4560 to book before the cold sets in.
Almost always, it’s a blocked or corroded direct-vent termination cap. Cold dense air plus a clogged cap prevents exhaust from leaving, the unit overheats, and the safety shutoff trips. We see this constantly in Baltimore’s spring and fall temperature swings. The fix is usually a cap cleaning or replacement, not a new fireplace.
In most cases, yes. We stock aftermarket damper assemblies, refractory panels, and caps that meet or exceed Gelco OEM specs, and we can source OEM parts when fitment demands it. If a part is truly obsolete, we’ll tell you and give an honest repair-versus-replace recommendation. You won’t pay for a guess.
It’s a camera inspection of the entire flue, firebox, damper, and cap, plus an assessment of the shared stack and flue separation if it’s a rowhouse. We document everything with photos and give you a written report. In a shared-flue Baltimore rowhouse, this is the inspection that catches a neighbor’s flue leak before it becomes carbon monoxide in your unit. Call (830) 251-4560 for details.
