Why Jericho Residents Choose Us for Gelco Service

We’ve been pulling apart and reassembling Gelco chimney systems across Nassau County for 17 years. Robert Garcia grew up in the Bronx, not far from Yankee Stadium, and learned building systems at Bronx Community College before apprenticing under a veteran sweep who drilled one lesson into him: a clean flue isn’t a luxury — it’s what keeps a family safe through a New York winter. That apprenticeship shaped how we approach every Jericho home we enter.

Jericho’s housing stock — those 1950s–1970s colonials and split-levels built during the Long Island suburban boom — presents a specific challenge that generic sweeps often miss. The dual-flue chimneys in these homes were originally designed for oil heat and wood fireplaces. When the oil burner converted to gas, the old flue was frequently abandoned in place. We’ve found deteriorating clay tile, cracked dividing walls, and Gelco caps improperly fitted to these modified stacks more times than we can count. Robert handles these inspections himself. Customers aren’t getting a rotating subcontractor who might not recognize what he’s looking at.

Our 1,096 verified reviews averaging 4.7 stars reflect what happens when the same person answers the phone, drives the truck, and climbs the ladder. We stock professional-grade materials from Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield — the same lines commercial contractors use. From routine sweep to full rebuild, the work stays in our hands.

Common Gelco Chimney Cleaning Problems We Solve in Jericho

• Gelco cap seal failure from freeze-thaw cycling. Jericho’s 15–25 annual freeze-thaw cycles fracture the mortar bed beneath Gelco caps, creating gaps that channel water directly into the flue. We remove the cap, re-bed it on proper crown sealant, and verify the mesh screen isn’t clogged with the leaf debris that accumulates on Jericho’s mature tree-lined streets.
• Stuck Gelco top-sealing dampers in seasonal-use fireplaces. Many Jericho homeowners fire up the hearth only for holidays and cold snaps. A Gelco damper that sits idle for ten months can seize from rust and creosote hardening. We free the mechanism, clean the flue throat, and lubricate the cable assembly — or replace it with a new Gelco unit if the frame has warped from moisture intrusion.
• Improper Gelco cap sizing on converted dual-flue chimneys. The standard Gelco cap ordered from a catalog rarely fits the irregular flue spacing left after an oil-to-gas conversion. Robert measures each flue center-to-center and often sources a custom-width Gelco multi-flue cap or fabricates a transition to ensure proper coverage without blocking draft.
• Creosote glazing in low-temperature burns. Jericho’s homeowners tend to burn manufactured firelogs or poorly seasoned wood for “ambiance” rather than heat. These cool, incomplete burns produce glazed creosote — a hard, tar-like deposit that standard brushing won’t remove. We apply mechanical rotary cleaning with poly chains, then verify with a chimney camera that the Gelco liner or original clay tile is fully exposed.
• Spalled clay liner debris interfering with Gelco damper closure. In 50–70-year-old Jericho chimneys, the original terra cotta flue liner sheds tile fragments that fall onto the smoke shelf and jam the Gelco damper in an open position. This leaves the flue permanently open to downdrafts and heat loss. We clear the debris, inspect the liner with a camera, and recommend either a HeatShield joint repair or a full stainless liner if the damage extends beyond isolated spalling.

Gelco Service in Jericho: What Local Conditions Mean for Your Equipment

Here’s the specific risk in Jericho that changes how we clean and inspect every Gelco-equipped chimney we encounter. In those classic split-level and colonial stacks along routes like Jericho Turnpike and the residential streets branching north, the abandoned oil-flue tile liner — cracked and unlined after the conversion to gas — sits immediately adjacent to the active fireplace flue within the same brick chase. A sweeping crew that only runs a brush down the “active” fireplace flue and never inspects the dividing wythe between the two will miss the compromised masonry wall that separates them.

We’ve found holes, missing mortar, and complete gaps in that dividing wall. Combustion gases from the gas appliance — carbon monoxide, primarily — can migrate through the breach into the fireplace flue and down into the living space when the fireplace damper is open or leaking. The Gelco cap on top may look fine. The fireplace may draw adequately. The hazard is invisible without a camera inspection of both flues and the wall between. Robert checks this on every Jericho dual-flue chimney we service. It’s not an upsell. It’s the difference between a sweep that protects your family and one that just moves a brush around.

The humid continental climate here compounds the problem. Moisture enters through deteriorated crowns on these seasonally-used chimneys, accelerates the clay tile spalling, and widens the gaps in that dividing wall. Jericho’s inland location avoids the salt-air corrosion that eats South Shore stacks, but the moisture intrusion is arguably worse because it goes unnoticed longer.

Gelco Models & Products We Service in Jericho

We work with the full Gelco residential line, including the standard multi-flue caps in galvanized, stainless, and copper finishes; the Gelco top-sealing damper systems (model 2000 series and later); Gelco spark arrestor screens; and the Gelco chimney pot and shroud assemblies that Jericho’s colonial-style homes sometimes specify for curb appeal. Our Jericho route trucks carry the most common Gelco cap sizes, damper flanges, and replacement mesh screens, which means most repairs don’t require a second appointment for parts.

We’re an independent service provider — not a Gelco-authorized dealer or factory affiliate. This matters because we’re free to recommend OEM Gelco components when they’re the right fit, or to suggest compatible alternatives from Olympia Chimney or Famco when a Jericho chimney’s modified dimensions don’t match current Gelco specs. Robert makes that call on-site, not from a script.

FAQs — Gelco Chimney Cleaning in Jericho

Are you an authorized Gelco dealer or factory service center?

No. Apex Chimney Cleaning Greater New York is an independent chimney service company with no manufacturer affiliation. We source OEM-compatible Gelco parts and install them to professional standards, but we also have the flexibility to recommend alternative brands when a Jericho chimney’s modified dimensions or condition call for a different solution. Call (866) 884-9512 if you want to discuss what’s actually on your roof.

Do you use genuine Gelco parts or aftermarket substitutes?

We install genuine Gelco caps, dampers, and accessories when the dimensions match and the application calls for them. For Jericho’s many converted dual-flue chimneys with non-standard flue spacing, we sometimes fabricate transitions or source compatible components from Olympia Chimney or Famco that meet the same material specs. Robert makes that determination on-site after measuring.

How long does a Gelco chimney cleaning take in Jericho?

A standard single-flue sweep and inspection runs 60–90 minutes. For Jericho’s typical dual-flue colonial or split-level chimney with the abandoned oil flue, plan on 2–2.5 hours — we camera-inspect both flues and the dividing wall between them, which takes time but catches the hidden failure modes that shorter inspections miss. Same-day scheduling is usually available; call (866) 884-9512 before noon.

Which Gelco models do you cover?

We service and install all current Gelco residential lines: multi-flue caps (galvanized, stainless, copper), top-sealing dampers (2000 series and later), spark arrestor screens, and chimney pot/shroud assemblies. If you’re unsure what model is on your Jericho home, Robert identifies it during the free estimate and explains whether repair or replacement makes sense.

How much does Gelco chimney repair cost in Jericho compared to neighboring towns?

Our pricing is consistent across Nassau County — we don’t inflate for zip codes. What varies is the condition we find. Jericho’s 50–70-year-old chimneys with abandoned oil flues typically need more inspection time and more complex cap solutions than newer construction in, say, a 1990s development. The dual-flue camera inspection adds $100–$120 to the base sweep, but it also catches the carbon-monoxide risks that a basic sweep won’t. For an exact quote on your specific Gelco system, call (866) 884-9512 — estimates are free, and we can usually get to you same day.
