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 Fireplace Services in Yonkers: What to Know First
We service Gelco fireplaces and inserts across Yonkers, from Lincoln Park to Crestwood, with most diagnostics completed same-visit and most parts sourced within 3 to 5 business days. A Gelco service call in Yonkers typically runs $149 to $229 for the diagnostic, and you’ll have a written price for any repair before we turn a single screw. We’re an independent Gelco service provider, not a factory warranty station, which means we fix what’s actually wrong and tell you plainly when a repair isn’t worth the money.
If you own a Gelco gas fireplace, wood-burning unit, or insert and it’s making noise, smelling odd, or refusing to light, call (551) 212-3526. Corrine Halstead and our Yonkers crew have worked on Gelco units in older colonials off McLean Avenue and in the newer builds near Ridge Hill. The camera goes down the flue on every visit, and the quote lands on paper before any work starts.

How Gelco Products Fail - and How We Fix Them
Gelco made solid mid-market fireplace boxes and inserts through the 1990s and 2000s. Most of what we see in Yonkers homes falls into a few predictable failure patterns. Here’s what actually goes wrong:
- Gelco direct-vent gas inserts (DV-series): pilot assembly dropout. These units run a standing pilot, and after 8 to 12 years the thermopile weakens. The flame lights, then drops out three minutes later. Homeowners often assume it’s the gas valve; it’s usually a $40 to $80 thermopile we can replace the same day. We test millivolt output before condemning anything pricier.
- Gelco B-vent and masonry fireplace boxes (MB-series): refractory panel cracking. The factory panels in these boxes are thin, and years of heat cycling causes hairline cracks that widen each season. Cosmetic cracks under 1/8 inch can wait; anything wider or any panel that has shifted is a carbon monoxide pathway into the wall cavity. We replace panels with OEM-spec refractory or a HeatShield resurfacing when the box is structurally sound.
- Gelco wood-burning inserts: blower motor burnout. The factory motors are sealed units, and when they go, they whine before they die. Gelco no longer ships every legacy motor, so we source quality aftermarket matches that bolt to the same housing. The fix is quiet, and we photograph the old and new part for your records.
- Gelco gas log sets (G-series): burner tube rust-through. This is a Yonkers humidity story more than a Gelco defect story. Homes near the Hudson and along the Saw Mill River Parkway see more moisture in the chase, and mild steel burner tubes eventually pinhole. The flame gets lazy on one side. We replace the burner assembly, not just the logs.
- Damper assemblies on Gelco prefab boxes: warped frames. The original cast-iron dampers on older Gelco boxes warp over decades and stop sealing. In Yonkers, that means heated air runs up the flue from October to March. We replace with a top-sealing damper when the throat damper is shot, which pays for itself in one or two heating seasons.
Every diagnostic comes with photos. The camera doesn’t lie, and neither does the quote.
Our Gelco Fireplace Services Process

This is what happens when you call us about a Gelco fireplace in Yonkers:
- 1
Call and schedule. A live person answers at (551) 212-3526. We book a two-hour window and text you when the tech is on the way, with the tech’s name and background-check confirmation.
- 2
Arrival and visual assessment. We inspect the unit, the surround, the wall cavity access, and the exterior termination. We’re looking for the failure mode before we even take the cover off.
- 3
Camera-scan and diagnostic. For any gas or wood unit connected to a flue, we run the camera per NFPA 211 Level 2 and record what we see. For a gas valve or pilot issue, we test with a manometer and millivolt meter, not guesswork.
- 4
Written price and parts decision. We quote OEM Gelco parts when they’re available and make sense for the age of the unit. When an aftermarket equivalent is the better call on a 15-year-old insert, we say so, with the part number and warranty terms in writing. You approve before we order or install anything.
- 5
Repair, test, document. We do the work, run the unit through full cycle testing, and hand you a written scope, the photo record, and the warranty on the repair. Every job is backed by our 365-Day Done Right Promise under the Haven Standard.

What moves the price: access difficulty, whether we need to cut into a chase, parts availability from Gelco’s distributor network, and whether the flue itself needs attention. Call (551) 212-3526 for a free estimate and we’ll give you a written number before any work begins.
Why Yonkers Homeowners Call Level Two Chimney Yonkers for Gelco Work

Yonkers has no shortage of general fireplace companies, but most of them don’t know a Gelco MB-series from a DV-series. We do, because Corrine Halstead has been taking these units apart since she picked up her first wire brush in a vocational program at Bronx Community College and went on to spend almost two decades on chimneys and fireplaces across Westchester County.
We run a camera on every job, quote in writing before anything starts, and back the work with the 365-Day Done Right Promise. If the fix for your Gelco unit involves the flue, we also handle liners and caps using materials from DuraFlex and HeatShield, so you’re not juggling two contractors for one fireplace problem. And if a competitor already wrote you an estimate, bring it in; we’ll give you a free second opinion on it.
FAQs
No. We perform service as an independent Gelco service provider, and our repairs use OEM Gelco parts or documented aftermarket equivalents wherever applicable. We provide the part numbers and a written record of the work on every job, which keeps your position solid if a future warranty claim is ever needed. Homeowners in Yonkers who’ve worked with us have never had a claim denied for independent service documented properly.
Yes, for most units made after about 1995. Gelco parts distribution is thinner than it used to be, so some legacy blower motors and damper assemblies require quality aftermarket matches. We’ll tell you the parts availability picture in plain terms at the diagnostic and give you the written price for whichever route you choose. Call (551) 212-3526 for a free estimate and we can check your specific model’s parts status before we even arrive.
Most diagnostics happen within 3 to 5 business days, and we keep common Gelco parts like thermopiles, thermocouples, and burner tubes in the van. If the part is in stock locally or in our inventory, the repair is often done same-visit. If it needs to be ordered from Gelco’s distributor channel, it’s typically 3 to 5 business days.
If the box itself is structurally sound and the repair is under $500, repair is usually the right call. If the refractory is crumbling, the burner pan is rusted through, and the flue liner needs a rebuild, you’re looking at a number that usually makes more sense as a new insert. We’ll give you both numbers in writing, with photos, so you can decide with evidence, not pressure.
We do. We work on units that use DuraFlex and HeatShield components regularly, among others. But for Gelco specifically, our Yonkers crew has seen enough of these boxes to know their failure patterns before the cover even comes off. Estimates are free; the camera’s included. Call (551) 212-3526.
