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 Cleaning & Sweep in Greenwich: What to Know First
We clean and sweep Gelco chimney systems throughout Greenwich, CT, with most jobs completed in a single visit. A standard Gelco chimney cleaning and Level 2 camera inspection runs $275-$425 depending on flue height, creosote class, and accessibility. You’ll get a written price before we touch a brush, a documented photo record when we’re done, and a straight answer about whether your Gelco liner is doing its job or quietly becoming a liability.
This page is for Greenwich homeowners who own a Gelco flue liner, Gelco chimney cap, or Gelco chase cover and want cleaning and sweeping done without the upsell theater. If you’re not sure what’s actually inside your chimney, the camera will tell us. Call (516) 399-5497 and we’ll get you on the schedule.

How Gelco Products Fail - and How We Fix Them
Gelco makes solid stainless liners, caps, and chase components. The trouble we see in Greenwich isn’t usually the metal failing. It’s what happens around it when the system gets ignored. Here’s what shows up in the field:
- Gelco 316L flexible liners with Class III creosote glazing. We see this most often in older Greenwich colonials where the previous owner burned green wood or skipped sweeps for five-plus years. Class III creosote is the shiny, tar-like glaze that bonds to the liner wall and becomes fuel. It needs mechanical removal (rotary chains or a specialized whip), not just a brush. Left alone, it’s a chimney fire waiting for a cold night. We clean it and document the liner wall before and after.
- Gelco rigid liner joints separating at the flue offset. Backcountry Greenwich estates tend to have taller, offset flues. When a rigid Gelco liner flexes with thermal cycling, the joints can open up. The symptom is a faint smoke smell in the house even when the damper is closed. Our camera catches the separation; the fix is reseating and re-securing the joint, not replacing the whole liner. We’ll show you the footage before we quote the repair.
- Gelco multi-flue caps with nested bird debris in the side screens. Near Cos Cob and Riverside, we pull bird nests, maple wings, and squirrel hoards out of Gelco cap screens every spring. A blocked screen doesn’t just look bad - it restricts draft and forces smoke back into the firebox. Corrine Halstead has cleaned enough of these to know the pattern: the debris clogs the screen before the cap crown even shows wear. We remove it, check the cap mounting, and sweep the flue.
- Gelco chase covers rusting along the lip where snow sits. Greenwich winters keep moisture on chase tops for weeks. Gelco’s older galvanized chase covers (pre-stainless era) rust at the folded lip, and the rust runs down the chase wall. During a sweep, we check the chase cover and note it in the photo record. If it’s weeping rust onto the chase but still structurally sound, we tell you honestly how long it can wait - and quote a stainless replacement in writing if it can’t.
- Gelco stove connections with soot buildup at the appliance adapter. In smaller Greenwich homes with wood stoves, we see heavy soot deposits where the Gelco connector meets the stove flue collar. This narrow point collects soot faster than the rest of the system. We disassemble the connector, brush the adapter, and reseal it. It’s a five-minute extra that keeps your draft strong and your stove from backpuffing.
One thing worth naming plainly: as an independent Gelco service provider, we don’t have a chart of factory warranty codes to hide behind. We inspect the actual metal in the actual flue and tell you what the camera shows. Corrine’s rule is simple: write up what you see, quote what it costs, and let the customer decide with the evidence in front of them.
Our Gelco Chimney Cleaning & Sweep Process

Here’s how a typical Gelco chimney cleaning job goes from first call to final photo, whether it’s a high-efficiency fireplace in a mid-century ranch or a wood stove in an old Cos Cob colonial:
- 1
You call (516) 399-5497. A live person answers, 24/7. We ask about your Gelco setup, the last sweep date, and any symptoms (smoke smell, poor draft, cap noise). We schedule a window that works and send a text when the tech is on the way.
- 2
We lay out the scope and write a price. Before a single tool comes off the truck, we go over what we’re cleaning, whether it’s a Level 1 or Level 2 scope, and what it costs. Written. Clause 1 of the Haven Standard: written price before any work starts. No “while we’re in there” surprises.
- 3
We sweep and camera the flue. We run the brush or rotary head, clear the creosote and soot, and then drop the camera down the full Gelco liner. We’re looking for joint separation, glaze you can’t see from the firebox, cap blockages, and liner integrity. You’ll see the footage on our screen or your phone.
- 4
We clean the firebox, damper, and smoke chamber. If you’ve got a Gelco-lined masonry system, the smoke chamber above the damper is where soot hides. We vacuum it, inspect the corbels and parging, and note any spalling brick that’s dropped onto the smoke shelf.
- 5
We show you the documentation. That means photos of the flue before and after, the cap, the chase cover, and any issue we found. If something needs repair, you get a written scope and price for that too - never a verbal “you should really think about this” followed by a mystery number.
- 6
We stand behind it. Every job is stamped with the 365-Day Done Right Promise. If it’s not done right, we make it right. And if you got a second quote elsewhere before calling us, bring it - we’ll give you a free second opinion on it.

AfterWhat Gelco Chimney Cleaning & Sweep Costs in Greenwich
Here’s honest pricing for the Gelco jobs we run most days in Greenwich. These are starting ranges; the written quote reflects what the camera and ladder actually show.
| Service | Typical Greenwich Price | What It Includes |

| Gelco chimney cleaning + Level 1 inspection | $275-$375 | Brush sweep, firebox and damper cleaning, visual check |
| Gelco chimney cleaning + Level 2 camera inspection | $325-$425 | Full sweep, camera scan of liner, joints, cap, photo record |
| Gelco cap cleaning or cap screen clearing | $95-$180 | Ladder or roof access, debris removal, mounting check |

| Creosote glaze (Class III) mechanical removal | $180-$350 add-on | Rotary head work, before/after camera verification |
What moves the price: flue height (a three-story backcountry estate chimney costs more to access than a single-story ranch), creosote class, cap condition, and whether we’re on a ladder or a roof that needs a harness. We’ll never charge you for a second-story surprise we could have seen from the ground. Call (516) 399-5497 for an exact written quote - estimates are free.
Why Greenwich Homeowners Call Level Two Chimney Greenwich for Gelco Work

Because we name what we find and price it in writing before we touch a brush. We’ve inspected and cleaned more than 38,000 chimneys since 2009, every one with a written price before work started and a documented record when it was done. The camera doesn’t guess. Neither do we.
Our techs are background-checked and uniformed, with license information on every page. We carry Gelco-compatible components and, where the system benefits, quality materials from DuraFlex and HeatShield as backup. If a cap needs replacement, we’ll tell you whether the Gelco original merits the premium or whether a DuraFlex alternative does the job at a fairer price - and quote both in writing. The point is a flue that works, not a parts invoice that flatters a manufacturer’s margin.
We’re independently owned and operated under the Haven Standard. That means Clause 4 on every visit: a documented photo record, because you should walk away with evidence, not a vague summary.
FAQs
Once a year if you burn regularly, and at least once every two years if you use the fireplace occasionally. We see Greenwich chimneys that got swept every year and liners that still look sound at 20 years; we also see five-year gaps that turned a simple sweep into a glaze removal and a liner discussion. The camera tells you which category you’re in, not a chart.
No. A proper brush or rotary sweep with the right diameter head does not damage a Gelco 316L liner. In fact, skipping cleaning is what voids warranties - most liner manufacturers require documented annual maintenance. We document every sweep with photos, so if a warranty issue ever comes up, you have the record. Call (516) 399-5497 to book your sweep.
Yes. The camera inspection shows corrosion, joint separation, warping, or perforation that a flashlight from the top can’t catch. If we see it, we’ll show it to you on the spot and give you a written replacement quote. What we won’t do is tell you the liner needs replacing because it looks old. Old and functionally sound is fine; cracked or perforated is a different conversation.
Most weeks, we get a technician to your home within three to five business days. If you’re smelling smoke inside or noticed cap damage after a storm, tell us on the call and we’ll do what we can to see you sooner. We will never, however, promise same-day service without knowing the schedule - a chimney sweep is booked, not rushed.
We made camera-scan documentation the default back in 2009, years before regulators or insurers asked for it, and it’s been Clause 4 of the Haven Standard ever since. You’ll see your flue before we clean it and after. Most companies charge for a flashlight look and call it an inspection. We don’t.
