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.
Gelco Fireplace Services in Ellicott City: What to Know First
We provide independent Gelco fireplace services in Ellicott City for gas fireplaces, wood-burning units, inserts, and dampers - most jobs completed in a single visit with no-hassle upfront pricing agreed before we start. A typical Gelco service call runs $180-$420 depending on the repair, and we carry common parts so you’re not waiting on a second trip. We’re not affiliated with Gelco; we’re an independent service provider who has worked on their equipment in Howard County homes for over two decades.
This page is for Ellicott City homeowners who own a Gelco fireplace, insert, or damper and want it fixed by someone who knows the difference between a Series 5000 and a Series 7000 without reading the manual. If that’s you, call (410) 305-7884. A live person answers, 24 hours a day.

How Gelco Products Fail - and How We Fix Them
- Series 5000 gas fireplace - failed thermopile or worn gas valve. We see this often in Ellicott City homes built during the 1990s expansion off Route 40. The thermopile weakens after 15-20 years of seasonal cycling; the pilot stays lit but the main burner won’t catch. We test millivolt output at the valve, replace with an OEM Robertshaw or a quality aftermarket equivalent rated for Gelco heat specs, and verify with a manometer reading before we leave.
- Series 7000 wood-burning fireplace - cracked refractory panels or shifted firebox joints. The Ellicott City freeze-thaw cycle is harder on these than the manufacturer expected. Moisture seeps in during humid summers, expands in January cold, and the refractory cracks at the stress points. We source Gelco-spec panels or use HeatShield refractory repair when the damage is surface-level, not structural. We photograph everything so you see what we see.
- Gelco fireplace insert - blower motor bearing failure or seized squirrel cage. These inserts work hard in older Ellicott City colonials with original chimneys. The blower runs 6-8 hours daily all winter, and the OEM motor isn’t always available same-week. We stock a cross-referenced aftermarket blower from our Famco supply line that matches CFM and amperage; we note the substitution on your invoice for warranty tracking.
- Top-sealing Gelco damper - corroded chain assembly or warped damper plate. The cast-aluminum plate warps when homeowners forget to open it before a hot fire, which we see more often than you’d think. In Ellicott City’s older neighborhoods near Main Street, the chimney draft can be marginal to begin with, so a stuck damper turns a smoky evening into a real problem. We rebuild the chain guide or replace the full assembly with a Copperfield damper if the frame is still square.
- Gelco direct-vent gas unit - blocked vent termination or failed pressure switch. The concentric vent cap collects leaf debris from Ellicott City’s mature oak canopy, especially on homes near Centennial Park. The pressure switch faults, and the unit locks out. We clear the termination, test draft with a digital manometer, and replace the switch with an OEM part - aftermarket pressure switches for direct-vent units don’t always hold calibration.
Our Gelco Fireplace Services Process
- 1
You call, a live person answers. We ask the model number if you have it, the symptoms, and whether the unit is gas or wood. We give you a ballpark range before we schedule.
- 2
We arrive in a marked truck, uniformed, background-checked. Russell Haines or one of our techs inspects the unit, the venting, and the surrounding structure. We look for what failed and what caused it.
- 3
Camera inspection if the flue is involved. The flue doesn’t lie - we just translate what it’s telling you. You see the photos on our tablet; we explain in plain English what needs doing now, what can wait, and what it costs.
- 4
Parts decision: OEM Gelco when it matters, quality aftermarket when it doesn’t. We stock DuraFlex liner sections, HeatShield refractory, and Famco blowers. If your repair needs a Gelco-specific casting or control board, we order it with a clear timeline - no guessing.
- 5
The repair, the test, the cleanup. We fire every gas unit through a full cycle, check for CO with a calibrated detector, and leave your hearth cleaner than we found it.
- 6
Written invoice, 90-Day Done Right Promise attached. If it’s not right, we come back. In writing, no arguing.
What Gelco Fireplace Services Costs in Ellicott City
These are real numbers from our last fifty Gelco service calls in Howard County. Your exact price depends on access, parts availability, and whether we find secondary damage during inspection.
| Service | Typical Range |
|---|---|
| Annual tune-up and safety check (gas or wood) | $89-$150 |
| Thermopile or thermocouple replacement | $180-$260 |
| Blower motor or fan assembly repair | $220-$380 |
| Damper rebuild or replacement | $280-$420 |
| Refractory panel replacement (per panel) | $180-$320 |
| Firebox crack repair with HeatShield | $350-$580 |
| Gas valve or control board replacement | $340-$520 |
What moves the price: OEM Gelco parts cost 20-40% more than quality aftermarket, and we quote both when there’s a safe choice. Jobs requiring roof access or chimney liner work add labor time. We give you the exact number before we start - the number on the estimate is the number on the invoice. Call (410) 305-7884 for a free estimate.
Why Ellicott City Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve been sweeping and repairing chimneys in Ellicott City since before the historic district got its current designation. Russell Haines learned the trade at Los Angeles Trade-Technical College, then spent the better part of two decades running calls across Howard County, including regular work near the Patapsco Female Institute ruins. That history matters because Gelco units from the 1980s and 1990s are still running in this town, and you can’t fake experience with obsolete controls.
We document every inspection with photos and a plain-English verdict. Our 90-Day Done Right Promise is backed in writing - if it’s not right, we make it right, no paperwork and no arguing. Our technicians are background-checked, uniformed, and carry the professional-grade brands that work with Gelco systems: DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield. When Gelco OEM isn’t available, we know what crosses over safely. We’ve been here over 42 years. We’ll be here when you need us again.
FAQs
No - the original Gelco factory warranty expired years ago on nearly every unit we see in Ellicott City. As an independent Gelco service provider, we use parts and practices that won’t compromise any remaining component warranty, and we note OEM versus aftermarket on your invoice for your records. If you’re unsure about coverage, call us at (410) 305-7884 and we’ll walk through it with you.
Common parts - thermopiles, blowers, dampers - we stock or can source within 2-3 business days. Obsolete Gelco castings or control boards may take 5-10 days; we’ll tell you before we order, and we won’t charge until the part is in hand. For an exact timeline on your model, call (410) 305-7884 with the serial number.
Repair if the firebox and venting are sound and the repair costs less than 40% of a comparable new insert. Replace if the firebox is cracked through, the chimney liner is unsized for modern efficiency standards, or you’ve already sunk repair money into the same component twice. We give you camera evidence either way - no guesswork, no pressure. Call for a free inspection.
Gas units: annually, before the first fire of the season. Wood-burning units: annually if you burn more than a cord per year, or every two years for occasional use. Ellicott City’s oak and hickory produce more creosote than the softwoods Gelco tested against, so we lean toward annual for wood-burning homeowners near Centennial Lake or Patapsco Valley State Park. Call (410) 305-7884 to schedule.
Gas units can develop combustion leaks or CO hazards without visible warning. Wood units accumulate creosote, which ignites at 451 degrees and can crack your flue liner, sending fire into wall cavities. Both risks are real, both are preventable, and both are why we answer the phone at midnight. Call (410) 305-7884 - estimates are free.
