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 Brooklyn, CA | Flint Chimney Sweep
We provide independent Gelco chimney cleaning and repair across our Brooklyn service area, and the one thing that sets our work apart here is simple: we know how Brooklyn’s pre-war housing stock and salt-laden coastal air shorten the life of Gelco stainless liners, so our inspections go looking for specific failure points other companies miss. That means a Gelco sweep from Flint Chimney Sweep isn’t a checkbox service, it’s a documented condition report on your liner, cap, and flue. Call (830) 251-4560 for a free estimate and a written price before anything comes off the truck.
Why Brooklyn Residents Choose Us for Gelco Service
Our techs have serviced Gelco stainless chimney liner systems across Brooklyn for over a decade, from Park Slope brownstones to Bushwick walk-ups. We know the specific alloys and warranty documentation Gelco requires, so independence never means guesswork. Hank Delano, who runs Flint Chimney Sweep, learned the trade through the building maintenance and construction technology program at Los Angeles Trade-Technical College and spent years doing hands-on chimney work before starting this company in 2002. When you call, you get a background-checked, uniformed technician who can tell you exactly what your firebox and flue liner look like and what, if anything, needs doing, without padding the invoice. That’s the Garrison Standard we operate under: every job gets a written price before work begins, and every repair carries a 365-day written guarantee.
We source genuine Gelco sales & service parts when a system is under 15 years old and structurally sound. For older liners with widespread pitting, we recommend a full sweep-and-replace using a Gelco-compatible aftermarket liner from HeatShield or DuraFlex. We never sell a rebuild if a targeted repair with OEM parts will restore safe drafting.
Common Gelco Chimney Cleaning Problems We Solve in Brooklyn
- Pinhole corrosion in Gelco 316L liners. Brooklyn’s salt-laden coastal air accelerates oxidation, especially on exposed roof sections where the liner passes through the chase. We see this most often within three to five miles of the waterfront. A camera inspection shows the exact location and depth of pitting before we recommend anything.
- Liner separation at the appliance collar. Constant freeze-thaw cycling in unheated Brooklyn basements and exterior chases causes the liner to work loose where it connects to the furnace or water heater. This is a carbon monoxide risk, not just a draft problem. We re-secure the collar and run a draft test before we leave.
- Creosote glaze on Gelco liners from improperly seasoned wood. Brooklyn’s older masonry fireplaces were never designed for modern inserts, and wet or green wood produces a hard, glossy creosote that’s difficult to remove without proper tools. We use mechanical rotary cleaning, not just brushes, to strip glaze down to the metal.
- Cap screen collapse from acidic soot and high humidity. Brooklyn’s humid summers and sooty flues corrode cap screens faster than most owners expect. A collapsed screen lets rain into the flue, which then corrodes the liner crown. We replace these with Gelco Pro Series stainless caps that hold up better in coastal conditions.
- Carbon monoxide backdrafting in multi-appliance flues. Brooklyn’s pre-war chimney stacks often share a single flue with a furnace, water heater, and fireplace. When a Gelco liner was installed without an insulated chase, backdrafting is common. This is the number-one reason our Brooklyn inspections run long: we’re checking the whole system, not just the fireplace.
Gelco Service in Brooklyn: What Local Conditions Mean for Your Equipment
Brooklyn’s pre-war chimney stacks often share a single flue with multiple appliances, the furnace, water heater, and fireplace all venting into one chase. Gelco liners installed without an insulated chase are the number-one reason we find carbon monoxide backdrafting in brownstone conversions. This multi-appliance flue sharing is rarely seen in newer suburban builds, which makes Gelco servicing in Brooklyn uniquely inspection-heavy. On Sixth Avenue in Park Slope, a homeowner called us after their Gelco-insulated liner started rattling during rainstorms. We ran a Level 2 camera inspection and found the cap screen had corroded away, letting water pool on the top plate. We replaced the cap with a Gelco Pro Series stainless model and re-secured the liner collar, stopping the leak and restoring proper draft. Two weeks later, a follow-up sweep showed zero moisture intrusion and a clean flue. That’s the kind of thing a standard sweep in another city would never catch, because the conditions that cause it barely exist anywhere else.
Gelco Models & Products We Service in Brooklyn
We service the full Gelco product line commonly installed in Brooklyn homes. That includes the Gelco 316L Stainless Steel Flexible Liner Kit, the Gelco Insulated Chimney Liner (double-wall), and the Gelco Pro Series Stainless Cap. When a system is under 15 years old and structurally sound, we source genuine Gelco replacement caps and liner sections. For older liners with widespread pitting, we specify a Gelco-compatible aftermarket liner from HeatShield or DuraFlex, chosen for the job, not for our margin. We keep common Gelco cap sizes and liner connectors stocked locally so Gelco in Long Beach and throughout Brooklyn service calls don’t stall waiting on a parts shipment.
Gelco Service Pricing in Brooklyn
A standard Gelco chimney cleaning in Brooklyn typically runs $189 to $349, depending on liner length, creosote condition, and access. A Level 2 camera inspection adds $150 to $300 and is the right call if you suspect corrosion, backdrafting, or water intrusion, and it’s often required after a liner separation or cap screen collapse. Cap replacement with a Gelco Pro Series stainless model runs $225 to $500 installed, including the part. What drives cost in Brooklyn specifically is flue access: pre-war brownstones with steep roofs and tight chases take longer than suburban single-story homes. Every estimate is free, in writing, and covers the exact scope of work before we start. Call (830) 251-4560 for a number that won’t change at the door.

FAQs – Gelco Chimney Cleaning in Brooklyn
You need a Level 2 inspection if you’ve had water intrusion, a new appliance installed, a chimney fire, or if the liner is over 10 years old and hasn’t been camera-checked. A standard sweep cleans creosote; a Level 2 inspection sends a camera through the liner to document corrosion, separation, and cap condition. In Brooklyn, we recommend a Level 2 on most first visits because multi-appliance flues hide problems a sweep alone won’t reveal. Call (830) 251-4560 to book one.
Yes, and faster than most owners expect. Brooklyn’s coastal air carries chloride that accelerates oxidation on exposed roof sections of Gelco 316L liners, especially where the metal passes through the chase. We regularly see pinhole corrosion within 10 to 15 years of installation within a few miles of the waterfront. A camera inspection will show exactly where pitting has started before it becomes a full liner failure. Call (830) 251-4560 and we’ll document what’s actually going on.
Acidic soot from burning wood reacts with Brooklyn’s high humidity to corrode cap screens faster in this borough than in drier inland areas. Once the screen collapses, rain enters the flue and corrodes the liner crown. We replace failed screens with the Gelco Pro Series stainless cap, which holds up better in coastal conditions. If you’re replacing the same cap every three or four years, there’s a better fix. Call (830) 251-4560 for a cap inspection.
Yes, in most cases. A separated collar is usually a mechanical failure from freeze-thaw cycling, not a full liner failure. We re-secure the collar, replace the connector if it’s damaged, and run a draft test to confirm the flue is pulling properly. If the liner itself is pitted or cracked, we’ll show you the camera footage and give you a straight recommendation on repair versus replacement. Nothing gets sold without evidence you can see. Call (830) 251-4560 to schedule a collar inspection.
Gelco liners are solid stainless steel, typically 316L alloy, and are a good choice for many Brooklyn homes. HeatShield is a cast-in-place ceramic system that rebuilds the existing flue rather than inserting a new liner, which can be better for oversized or damaged pre-war terra cotta flues. Both have a place in Brooklyn. The right choice depends on your flue size, current liner condition, and whether you’re venting multiple appliances. Call (830) 251-4560 and we’ll explain which fits your setup, with pricing for both.
