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 Fireplace Services in Bangor: What to Know First
We provide independent Gelco fireplace services in Bangor and the surrounding Slate Belt, with most repairs scheduled within a few days and completed in a single visit. A typical Gelco gas fireplace service runs $189-$289, while firebox or damper repairs on Gelco wood-burning units usually fall between $340-$780 depending on parts. We do not quote over the phone for what we have not seen, and we do not sell repairs a chimney does not need.
This page is for Bangor homeowners who own a Gelco fireplace, insert, or gas log set and need service from technicians who know the difference between a Series 600 direct-vent and an older pre-fab firebox. If that is your situation, call (610) 609-7634. A live person answers, day or night.

How Gelco Products Fail - and How We Fix Them
- Series 600 direct-vent gas fireplaces - intermittent pilot failure. The SIT valve and pilot assembly on these units, common in 1990s Bangor ranch homes, accumulate oxide from the hard well water throughout Northampton County. The pilot lights, then drops out after ten minutes. We clean the pilot orifice with a proper reamer, test micro-amp draw with a meter, and replace the thermopile only when it reads below 325 mV. A generic “universal” pilot kit will not seat correctly in the Gelco bracket.
- Gelco wood-burning inserts - cracked refractory panels. The 26-inch and 36-inch inserts sold heavily in the Poconos and Slate Belt during the 2000s use refractory cement panels that spider-crack from thermal shock, especially when homeowners burn green oak or ash from local woodlots. We source OEM-pattern panels from Copperfield that match Gelco’s original spec, or we pour a HeatShield cerfractory mix for larger breaches. Either way, we photograph the damage before quoting.
- Pre-fab firebox units - rusted damper frames. Gelco’s builder-grade pre-fab fireboxes installed in Bangor’s 1970s and 1980s split-levels have galvanized steel dampers that corrode where the flue meets the firebox. The damper plate jams open, bleeding heat all winter. We fabricate a stainless replacement from Olympia Chimney stock or install a Lock-Top damper on the flue tile if the frame is too far gone to salvage.
- Direct-vent flex runs - collapsed or sagging liners. Gelco’s flex runs in exterior chase walls, especially on north-facing Bangor homes, sag where the support brackets spaced too far apart let condensation pool and freeze. The draft reverses, sooting the glass and the house. We pull a DuraFlex 316Ti replacement with proper support spacing every six feet, and we insulate the chase top to cut condensation.
- Gas log sets - burner pan flashback. Older Gelco vented log sets with the 18-inch and 24-inch ANSI-certified burners develop flashback when the ember bed shifts and blocks primary air ports. Homeowners smell gas or see flame lifting off the front log. We reset the media to factory placement, check orifice sizing against the Bangor gas pressure reading (typically 7 inches w.c. for NG here), and replace the burner only if the porting is eroded.
Our Gelco Fireplace Services Process
- 1
Call and schedule. A live person answers at (610) 609-7634. We ask the model number if you have it, the symptom, and whether the unit is gas or wood. We book a window that works for you.
- 2
Level-2 camera inspection and diagnostics. Our technician arrives in uniform, background-checked, with a camera and inspection mirror. For gas units, we test pressure, millivolt output, and draft. For wood units, we scan the flue and firebox. You see the photos on the spot. A clean flue does not need a sales pitch.
- 3
Parts decision - OEM or quality aftermarket. We stock common Gelco wear parts: pilot assemblies, thermopiles, refractory panels, damper hardware. If your unit needs a discontinued component, we source from Famco or fabricate from Copperfield and Olympia Chimney materials that meet or exceed original spec. We explain the trade-off and the price difference before ordering.
- 4
The repair, tested before we leave. We complete most Gelco jobs in one visit. Gas units get a full combustion analysis. Wood units get a draft test and a smoke-pencil check for spillage. The technician runs the unit through a complete cycle while you watch.
- 5
Written report, upfront invoice, and our 90-Day Done Right Promise. You get photos, a plain-English verdict, and an invoice that matches the estimate. If anything is not right, we come back. In writing, no arguing.
- 6
Cleanup and next-service reminder. We leave the hearth cleaner than we found it. For wood-burning Gelco units in Bangor’s heavy-burner households, we note a 12-month sweep interval. For gas units, we mark 24 months.

Why Bangor Homeowners Call Hearthstone Chimney Co. for Gelco Work
We are not a franchise. We are not a one-truck operator who may answer next year. Hearthstone Chimney Co. has served Bangor and the Slate Belt for over 42 years, and we plan to be here when your Gelco unit needs its next service.
Our 90-Day Done Right Promise means if the pilot drops out again, if the draft still reverses, if anything is not right - we come back. No paperwork to dig up, no argument about whether it is “covered.” Krafted right, every time. Your home first. Standing behind it.
Russell Haines and our technicians know Gelco products because we have worked on them in Bangor basements, Bangor split-levels, and the older homes near the Bangor Borough Historic District where the flues are tight and the clearances are unforgiving. When a Gelco part is discontinued, we have DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield materials to build a proper repair. Photos you can see. A plain-English verdict. A square deal: no surprises on the bill.
FAQs
No. As an independent Gelco service provider, we use warranty-safe practices and OEM-spec parts, though Gelco’s original factory warranty on units over twenty years old has typically expired regardless of who performs the work. For newer units still under warranty, we document our service with photos and part numbers to protect your coverage. Call (610) 609-7634 if you need help determining your warranty status.
Yes, for most models. We stock common wear parts for the Series 600 direct-vent line and the 26-inch and 36-inch wood inserts. For discontinued components, we fabricate equivalents from Olympia Chimney and Copperfield materials or adapt Famco hardware to fit. We do not install “universal” parts that compromise safety or function. If a part is truly unavailable, we tell you plainly and discuss replacement options.
Replacement becomes the honest recommendation when the firebox or heat exchanger is cracked beyond safe repair, or when parts are unavailable and the unit is past 75% of a new install cost. Until then, repair is usually the better value. We make this call with camera evidence you can see, not a sales pitch. Many Bangor homeowners are surprised how much life a proper repair adds to a 1990s Gelco unit.
Most repairs are scheduled within a few days, and we complete most in a single visit. During peak burning season, October through February, the wait may stretch to a week or two. We do not overbook. If your gas fireplace is producing odors or your wood unit is showing smoke spillage, call (610) 609-7634 - a live person answers 24 hours a day to determine if the situation needs immediate attention.
Delayed service on a Gelco gas unit leads to pilot fouling, delayed ignition from dirty burners, and eventually heat exchanger corrosion from acidic condensation - especially in Bangor’s cold, damp shoulder seasons when the unit short-cycles. These are fixable problems until they are not. A skipped $189 tune-up becomes a $2,400 replacement. Call (610) 609-7634 for an exact quote - estimates are free.
