This page is for Fairfax homeowners with a Gelco fireplace that’s misbehaving, or aging, or quietly becoming a liability. We’re not a Gelco dealer and we’ve never claimed to be one. We’re the independent crew in Fairfax that opens the firebox, names the fault in plain terms, and hands you a written scope with photos attached.

How Gelco Products Fail - and How We Fix Them

• Gelco gas log sets with lazy yellow flames and black soot on the glass. This is usually a clogged burner port or a misaligned log touching the thermocouple. If the ceramic logs have shifted after cleaning, the flame pattern collapses and you get soot instead of heat. We pull the logs, clean the burner ports with the correct diameter pick (not a paperclip), reset the log placement to the manufacturer’s diagram, and test the millivolt system before we call it done.
• Gelco direct-vent inserts that short-cycle or shut off after ten minutes. In Fairfax, we see this most often in dens and converted garages where homeowners added insulation and tightened the room’s air envelope. The unit overheats because the venting’s intake is starved. The fix is venting clearance and, in about half the cases, a new thermopile. But we only recommend the thermopile after a camera and a meter tell us the pilot’s actually dropping out rather than the high-limit switch tripping.
• Gelco vent-free log sets with a sulfur or kerosene smell after the first season of use. This is a known characteristic of vent-free burners running on natural gas with high mercaptan levels, which Fairfax County’s gas supply carries more of in winter. The smell is not always a leak, but we never tell a homeowner that without a gas sniffer reading on the valve, the supply line, and the fitting pack. If it’s the burner producing aldehydes from airborne dust, we’ll say so and show you the reading. If it’s a cracked line, we cap it and write the repair.
• Gelco wood-burning fireplaces with firebox panels that crack along the back wall within five years. The refractory panels on many Gelco builders-grade boxes are thinner than what you’d get in a masonry firebox, and Fairfax’s freeze-thaw cycle works on any moisture that finds the seam. Once a panel cracks, heat passes to the steel shell, and the metal warps. We replace the panels, and if the shell has started to bow, we’ll tell you whether the box can be saved or whether you’re looking at a firebox rebuild with HeatShield or a new refractory system.
• Gelco dampers that seize open, letting December air pour down the chimney and June AC escape up it. The damper track on many Gelco builder models is a thin steel channel that rusts and jams after six or seven Fairfax winters. We free it, lube it with a high-temp graphite compound, and if it’s warped beyond function we’ll quote a top-sealing damper, which actually pays for itself faster in Fairfax than in most markets because of our winter-to-summer swing.

Our Gelco Fireplace Services Process

1. 1
   Call and talk to a person. Our phones are answered live, 24/7. You tell us the symptom, what kind of Gelco unit you have, and when you’d like us there. We text you when the tech is on the way.
2. 2
   Arrival and inspection. A background-checked, uniformed technician arrives, drops a mat, and opens the unit. We run a camera inspection of the firebox, the flue, and all accessible venting. This is NFPA 211 Level 2, and it’s included on every visit, not as an add-on.
3. 3
   Diagnosis with evidence. If the pilot is dropping out, we show you the reading. If the logs are misaligned, we show you the photo. If the firebox panel is cracked, you see the crack and what it’s letting the heat reach. Corrine Halstead’s rule applies: the camera tells you what the chimney is; the written quote tells you what the fix costs. Everything else is just conversation.
4. 4
   Written quote with three lines. We pull OEM Gelco parts where they matter and quality aftermarket where they honestly don’t, and we show you the cost for each option. Scope, price, warranty, all in writing, before anything is disassembled.
5. 5
   Repair and test. We make the fix, run the unit through its full sequence, check clearances, gas readings, and flame picture. If it’s a wood-burning unit, we’ll also tell you the creosote class we found and whether a sweep is needed for safety.
6. 6
   Documentation and the Done Right Promise. You get a photo record of what was found, what was fixed, and the final condition. Every job is backed by the 365-Day Done Right Promise: if it’s not done right, we make it right.

What Gelco Fireplace Services Costs in Fairfax

Here’s the honest range, in dollars, for the Gelco work we see most in Fairfax.

• Gelco gas log set service (cleaning, burner port clearing, log reset, thermocouple test): $195-$345
• Thermopile or thermocouple replacement: $225-$395
• Firebox refractory panel replacement (single panel): $290-$550 depending on panel size and access
• Damper repair or replacement: $180-$475 depending on whether we’re freeing the track or installing a top-sealing damper
• Full Level 2 camera inspection with written report: $249, credited toward any repair we perform

What moves the price: whether the unit is a builder-grade Gelco insert or a mid-tier direct-vent, whether we’re working behind a facing that has to come off, and whether OEM parts are the only safe call on your particular unit. You’ll never hear “call for pricing.” You’ll get a written quote with photos, and we’ll stand behind the number.

Estimates are free. Call (571) 443-8256 and we’ll come out, put a camera on it, and hand you a number in writing.

Why Fairfax Homeowners Call Level Two Chimney Fairfax for Gelco Work

We’ve been in Fairfax long enough to know that the fireplaces in the older colonials near the Fairfax County Government Center corridor are dying a generation ahead of the inspection schedule. Flue liners crack, dampers seize, and builder-grade Gelco boxes need firebox attention before most homeowners think to look. We started running a camera down every flue in 2009, before regulators or insurers asked for it, and that practice became Clause 4 of the Haven Standard: a documented photo record on every visit, running continuously since. We’ve now inspected and cleaned more than 38,000 chimneys, and every single one of those jobs had a written price before work started and a documented record when it was done.

We know Gelco’s failure points, but we also service the alternatives, because sometimes the right fix is a DuraFlex liner or a HeatShield resurfacing instead of another Gelco part. That matters. A contractor who only sells one fix will find a reason to sell it to you. We’ll show you the camera and tell you when a repair will safely hold and when it won’t. Bring us a competitor’s written quote and we’ll give you a free second opinion on it.
