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.

This page is for Gelco owners in Newark who want to know what happens during a sweep, what it costs, and what we actually find inside these units. As an independent Gelco service provider, we’re not tied to the manufacturer’s script. We report what the camera shows, not what the brochure promises. Corrine Halstead, our owner, has been servicing Newark chimneys long enough to know that Gelco units have their own set of habits: some good, some worth watching closely.
How Gelco Products Fail, and How We Fix Them
Gelco fireplaces and stoves are generally well-built, but any appliance that burns wood for years in a Newark row house will eventually show wear. Here’s what we actually see on Gelco jobs across Newark, from the Ironbound to Forest Hill:
- Air-circulating gel fuel residue on fireplace doors and surrounds. While Gelco is better known for vent-free and direct-vent gas fireplaces, we still service plenty of older Gelco gel-fuel units in Newark condos and apartments. The gel fuel leaves a sticky, stubborn residue on glass and surrounds that standard fireplace cleaners won’t cut. We use a specific citrus-based solvent followed by a ceramic-glass polish that removes the haze without scratching the surface. This is the most common Gelco-specific cleaning issue we see in Newark’s older high-rise and mid-rise buildings.
- Direct-vent flue collar sealant failure at the unit top. On Gelco direct-vent models, the sealant around the flue collar where the vent pipe exits the unit dries out and cracks over time. Newark’s freeze-thaw cycles accelerate this. The symptom is a faint exhaust smell in the room, often mistaken for a draft issue. We remove the old sealant, clean the mating surfaces, and re-seal with a high-temp silicone rated for direct-vent use, then verify the seal with a smoke test. When we find this on a Gelco during a routine sweep, the fix usually adds about $75 to $95 to the job and takes 20 minutes.
- Ceramic fiber log deterioration contaminating the burner. Gelco gas log sets eventually shed ceramic fiber particles as they age, especially if they’ve been handled roughly during a previous cleaning. Those particles drop down into the burner ports and cause uneven flame patterns and incomplete combustion. During a Gelco cleaning, we carefully lift the logs, vacuum the burner assembly with a soft-bristle attachment, and document the log condition with photos so you can see whether replacement is needed. This is a case where our documented photo record, required under Clause 4 of the Haven Standard, matters: you see the same images we see.
- Pilot assembly and thermopile carbon buildup on Gelco vent-free models. Vent-free Gelco units build carbon on the pilot assembly faster than vented units, especially in Newark homes where windows stay shut from November to March. The symptom is a pilot that won’t stay lit or a flame that lifts off the burner. We use a small wire brush and compressed air to clean the pilot orifice and thermopile, then check the millivolt reading to confirm the thermopile is still producing enough voltage. If the thermopile is weak, we show you the reading and quote the replacement before ordering anything.
- Flue liner and creosote buildup from wood-burning Gelco fireplace inserts. For Gelco wood-burning inserts installed in older Newark masonry chimneys, the original clay flue liner is often still in place and badly deteriorated. We regularly pull Class III creosote from these flues: that’s the glossy, tar-like creosote that’s concentrated fuel and the primary driver of chimney fires. We remove it mechanically with rotary rods and brushes, then run the camera to document what’s left. If the liner is cracked or spalling, we tell you plainly and quote a stainless liner from DuraFlex or HeatShield, not because we’re selling liners, but because a cracked clay liner lets heat and gases reach the masonry, and that’s how chimney fires start.
Our Gelco Chimney Cleaning & Sweep Process

Every Gelco job in Newark follows the same sequence, and it’s all documented. Here’s what happens from call to cleanup:
- 1
Call and price. You call (862) 245-4309 and talk to a live person. We ask about your Gelco model, when it was last swept, and what you’re seeing or smelling. Before we hang up, you’ll have a written price range for the visit. No “we’ll see when we get there” pricing.
- 2
Arrival and floor protection. Our technician arrives in uniform, lays down drop cloths from the door to the hearth, and sets up a HEPA vacuum. You’ll get a text before we arrive so you’re not waiting around.
- 3
Initial inspection and camera scan. Before we sweep, we run the camera down the flue and document everything: liner condition, creosote class, obstructions, and the condition of the Gelco unit itself. This is an NFPA 211 Level 2 inspection, and it’s included in the price. The camera doesn’t negotiate. It just shows what’s there.
- 4
The sweep. We sweep the flue with appropriately sized brushes, clean the smoke chamber and smoke shelf if it’s a masonry setup, vacuum the firebox, and clean the Gelco logs, burner, glass, and surrounds. For gel-fuel residue, we use the citrus solvent process described above.
- 5
Post-sweep camera pass and documentation. After the sweep, we run the camera again. You’ll see the before and after images side by side on our tablet. If anything needs repair, we show you the image, explain what it means in plain terms, and hand you a written quote before we do anything else.
- 6
Written report and warranty. You walk away with dated photos, camera footage, a written scope of what we did, and the 365-Day Done Right Promise in writing: if it’s not done right, we make it right. That’s Haven Standard Clause 1 and Clause 4, and we’ve done it this way since Corrine started running crews in Newark.

What moves the price: flue height, creosote classification, access (Newark roof pitches vary a lot from block to block), and whether you have a Gelco unit that needs gel-fuel residue work on top of the sweep. Homeowners with a competitor’s written estimate can bring it to us for a free second opinion. Estimates are free, always in writing, and never hinge on a discount that expires if you don’t sign same-day. Call (862) 245-4309 and we’ll give you an exact number before anyone books the job.
Why Newark Homeowners Call Level Two Chimney Newark for Gelco Work

We’ve cleaned and inspected more than 38,000 chimneys since 2009, and every single one got a written price before work started and a documented record when it was done. For Gelco owners in Newark, that matters because these units aren’t exotic. Most companies will sweep them the same way they sweep everything else, and then hand you a vague invoice. We don’t do vague.
Our techs know Gelco’s quirks: the residue patterns on gel-fuel units, the sealant points on direct-vent collars, the burner contamination issues on older log sets. We also service the brands that sit alongside Gelco in Newark homes, like DuraFlex and HeatShield for liners, so when a Gelco insert needs a new liner, we’re not guessing about which aftermarket components fit. The 365-Day Done Right Promise applies to every job, and it’s stamped on your paperwork. Background-checked, uniformed technicians. A live person answers the phone 24/7. And you get the photo record whether or not anything is wrong. Corrine grew up in Queens and spent her early trade years studying masonry and ventilation systems at New York City College of Technology in Brooklyn. She’s been working Newark chimneys long enough to know a Gelco’s habits without having to open the manual twice.
FAQs
Most Gelco wood-burning fireplaces and stoves should be swept annually or after every 40 to 50 fires, whichever comes first. Gas and gel-fuel Gelco units don’t need a flue sweep in the traditional sense, but they still need an annual service to clean burner ports, check seals, and inspect the venting. Call (862) 245-4309 and we’ll tell you exactly what your unit needs.
No. Routine cleaning and sweeping as described in your Gelco owner’s manual keeps the warranty valid. We use non-damaging methods and document the work with photos, which is exactly what a warranty claim needs if something else goes wrong. We don’t modify anything without showing you the evidence and getting written sign-off.
It’s usually a cleaning issue first: carbon buildup on the thermopile or pilot orifice reduces flame quality and millivolt output. We clean it and test the reading before recommending any parts. If the thermopile is genuinely weak, we’ll show you the number and quote the replacement as a separate line item. Estimate is free; the decision is yours.
Most of the time, yes. We carry high-temp silicone and the tools needed to clean and re-seal Gelco direct-vent collars on the truck. If we find the leak during the sweep, we’ll show you the cracked seal in the camera footage and quote the repair on the spot. It usually adds $75 to $95 and takes about 20 minutes.
Yes. A camera scan is included in every Gelco visit, not just the liner checks. It’s Clause 4 of the Haven Standard: a documented photo record on every job. If your liner is spalling or packed with Class III creosote, you’ll see it on the tablet and get a written price if you want it addressed. No upsell, no pressure. Call (862) 245-4309 to book.
