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 Towson: What to Know First
As an independent Gelco service provider in Towson, we repair, service, and restore Gelco gas fireplaces, wood-burning units, and inserts - most jobs completed in a single visit with upfront pricing that matches the final invoice. A typical Gelco service call runs $150-$450 depending on whether we’re tuning a burner assembly or replacing a firebox panel, and we carry common Gelco parts on our trucks to avoid ordering delays. This page is for Towson homeowners who own a Gelco fireplace and want it fixed by technicians who know the difference between a Series 38 damper and a Series 42 without reading the manual twice. Call (443) 785-3816 anytime - a live person answers, day or night.

How Gelco Products Fail - and How We Fix Them
- Series 38 gas fireplace - pilot assembly carbon buildup. The standing pilot on Series 38 units gums up faster in Towson’s humid summer months when the fireplace sits idle. We disassemble the pilot hood, clean the orifice with a proper non-abrasive pick, and test flame rectification with a multimeter before we leave. A new OEM pilot assembly runs about $180-$220 installed if cleaning won’t hold.
- Series 42 wood-burning fireplace - cracked refractory panels. These panels take the direct flame hit and develop hairline cracks after 8-12 seasons of Towson’s freeze-thaw cycles. We measure the panels in place, source Gelco-spec refractory or HeatShield panel systems if OEM is back-ordered, and reset them with proper expansion gaps so they don’t spall next winter.
- Gelco fireplace insert - blower motor bearing failure. The convection blowers on older Gelco inserts run loud, then seize. We test amperage draw first; if the motor’s drawing high amps, we replace with an OEM-equivalent Dayton or Fasco motor rated for the same CFM and temperature range. The wrong motor burns out in a season.
- Series 38/42 shared chimney top - deteriorated chimney cap seal. Gelco’s factory caps use a single-layer seal that Towson’s driving rains exploit after about seven years. We install Famco or Copperfield replacement caps with double-seal construction and stainless mesh, or rebuild the crown with HeatShield CrownSeal if the concrete’s spalled underneath.
- Gelco gas valve - slow leak at the thermocouple connection. The brass thermocouple nut on pre-2010 Gelco valves fatigues from thermal cycling. We don’t just tighten and hope; we bubble-test the joint, replace the nut and ferrule with OEM brass, and verify with a digital manometer held for ten minutes. A gas leak is not a “wait and see” item.
Our Gelco Fireplace Services Process
- 1
Call and schedule. A live person answers (443) 785-3816, asks what you’re seeing or smelling, and books a window that works. We confirm upfront that there’s a $89 Seasonal Tune-Up available, or a full diagnostic if symptoms point to a specific failure.
- 2
Arrival and documentation. Our technician arrives uniformed, background-checked, and with a camera and tablet. We photograph the unit, the data plate, and any visible damage before touching a tool.
- 3
Diagnosis with camera inspection. For wood-burning Gelco units, we run a Level-2 camera up the flue to check for creosote glazing, liner gaps, or masonry deterioration. For gas units, we test gas pressure, valve operation, and thermopile output under load. You see the photos; we give a plain-English verdict.
- 4
Parts decision - OEM or quality aftermarket. If Gelco OEM is in stock or available within 48 hours, we quote it. If it’s back-ordered (common on discontinued Series 38 refractory), we quote a DuraFlex, HeatShield, or Famco equivalent that meets or exceeds Gelco spec, with the trade-off explained in writing.
- 5
Repair and test. We complete the work, run a full combustion analysis on gas units or a draft test on wood units, and clean the work area. The technician walks you through what was done and what to watch for.
- 6
Written guarantee. You get the 90-Day Done Right Promise in writing - Krafted right, Every time, Your home first, Standing behind it. If it’s not right, we come back. No paperwork to dig up, no arguing.

Why Towson Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve been on Towson roofs and in Towson basements for over 42 years, from the older colonials off York Road to the rowhouses near Goucher College. Russell Haines and our crew know Gelco units because we’ve serviced them since the 1990s, back when the Series 38 was new and the manual was actually printed on paper. We document every inspection with photos you can see and a plain-English verdict - no jargon, no scare tactics. If a Gelco part is discontinued, we have relationships with DuraFlex, HeatShield, and Famco distributors to source equivalents that fit and function correctly. The 90-Day Done Right Promise covers every job in writing. A square deal: no surprises on the bill. We’ll be there when we say. A clean chimney doesn’t announce itself - it just works.
FAQs
No. As an independent Gelco service provider, we use OEM or OEM-equivalent parts and document our work, which satisfies warranty requirements for routine maintenance and repair. Gelco’s warranty covers manufacturing defects, not who opens the access panel. If your unit is still under original warranty, we’ll note that on the invoice and flag any defect that should go to Gelco directly. Call (443) 785-3816 and we’ll check your warranty status before we book.
Common Gelco parts - pilot assemblies, blowers, refractory panels for current series - arrive in two to three business days from regional distributors. Discontinued Series 38 and early Series 42 parts can take five to seven days or require us to source DuraFlex or HeatShield equivalents. We stock the fast-moving items because Towson’s burning season doesn’t wait, and we’ll tell you honestly if a part hunt isn’t worth the cost of the repair.
Repair if the firebox and flue are sound and the repair costs less than 40% of a comparable new insert. Replace if the firebox is cracked through, the flue liner is deteriorated, or you’re facing multiple major repairs that exceed that threshold. We don’t sell new Gelco units, so our recommendation is based on what we find in your flue, not what we have in a warehouse. The camera inspection shows you exactly what we see.
Gas Gelco fireplaces: annually, before the first fire. Wood-burning Gelco fireplaces: annually if burned regularly, or per the NFPA 211 standard. Towson’s oak and hickory firewood burns hot but builds glazed creosote in the shoulder seasons when fires are small and smoldering. An $89 seasonal tune-up catches what a casual look won’t. Call (443) 785-3816 to schedule before burning season fills our calendar.
Delayed maintenance on a Gelco gas unit leads to incomplete combustion, elevated carbon monoxide risk, and eventually component failure that costs more than prevention. The thermopile weakens, the valve gets sticky, and the blower runs dirty until the bearings seize. We find most “sudden” failures are gradual problems the homeowner couldn’t see. A clean chimney doesn’t announce itself - it just works. Call (443) 785-3816 for a free estimate.
