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 Falls Church: What to Know First
We provide independent Gelco fireplace services in Falls Church, with most repairs completed in a single visit and upfront pricing agreed before any work begins. A standard Gelco gas fireplace service runs $180-$280; firebox or damper repairs on older Gelco wood-burning units typically fall between $340-$650. Every job ends with a written 90-Day Done Right Promise, and estimates are always free.
This page is for Falls Church homeowners who already know they own a Gelco fireplace, insert, or damper and need a technician who understands the difference between a Gelco GVF series venting issue and a generic gas-valve problem. You can reach us any hour at (571) 489-4365. A live person answers.

How Gelco Products Fail - and How We Fix Them
- GVF42 and GVF36 direct-vent gas fireplaces: The pilot assembly on these units collects condensation residue during Falls Church’s humid shoulder seasons when the unit sits idle. We disassemble the pilot bracket, clean the orifice with a non-abrasive reamer, and test flame rectification before reassembly. Replacement pilot assemblies are available, but nine times out of ten the original cleans up fine.
- Gelco fireplace inserts (wood-burning, pre-2010): The cast refractory panels crack from thermal cycling, especially when homeowners burn unseasoned oak common in Northern Virginia. We measure the firebox to the sixteenth, source matching Gelco-spec refractory or upgrade to HeatShield Cerfractory foam for a longer-lasting repair. The insert stays put; we work around it.
- Gelco top-sealing dampers: The stainless cable frays where it passes through the chimney crown, particularly on homes near the West Falls Church Metro corridor with older concrete crowns that spall. We inspect the cable run with a chimney camera, replace just the cable if the damper plate is sound, or swap the entire assembly for a new Gelco unit if the frame has warped from heat exposure.
- Gelco gas log sets with intermittent ignition: The thermopile voltage drops below 325mV after five to seven years, causing the main burner to delay or fail. We test millivolt output under load, clean the thermopile contacts, and replace with an OEM Robertshaw or White-Rodgers equivalent - never a universal fit that voids the Gelco burner warranty.
- Gelco chimney caps and chase covers: The galvanized steel models installed in the 1990s rust through at the drip edge, letting water run directly onto the flue liner. We fabricate a replacement in 24-gauge stainless or copper, or source a Gelco-compatible cap from Famco if the homeowner wants to keep the original profile. In Falls Church, we see this most on split-levels built in the 1970s near Graham Road.
Our Gelco Fireplace Services Process
- 1
Call and schedule. A live person answers, asks the model number if you have it, and books a window. No deposit required.
- 2
Arrival and diagnosis. Our technician arrives in a marked van, uniformed, and starts with a Level-2 camera inspection. You see the footage on a tablet as we explain what we’re seeing.
- 3
Parts decision. If the repair needs components, we check Gelco OEM availability against quality aftermarket options from our standard inventory - DuraFlex venting, HeatShield refractory, Famco caps. We tell you which we’re recommending and why, with prices attached.
- 4
The repair. Most Gelco fireplace services, damper repairs, and firebox patches finish in one visit. We work clean, lay runners, and vacuum before we leave.
- 5
Testing and documentation. Gas units get a combustion analysis. Wood-burning units get a draft test. You receive photos, a plain-English verdict, and the invoice matching the estimate.
- 6
The promise. The 90-Day Done Right Promise goes in writing. If something isn’t right, we come back. No paperwork, no arguing.

Why Falls Church Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve been answering the phone with a live person for over 42 years, and we’ve worked on Gelco products since they were a dominant brand in Northern Virginia new construction during the 1990s. Russell Haines learned masonry and ventilation at Los Angeles Trade-Technical College before running crews across this area for the better part of two decades, including plenty of seasons in the older colonials near the West Falls Church Metro corridor. Our technicians carry Gelco-compatible parts on the truck, but we’re also fluent in DuraFlex venting and HeatShield refractory when those make more sense for the repair. The 90-Day Done Right Promise is in writing. The price on the estimate is the price on the invoice. If it is worth heating your home with, it is worth doing the chimney right.
FAQs
No - the original Gelco product warranty expired years ago on most units we see in Falls Church. For newer Gelco products still under warranty, our use of OEM-spec parts and manufacturer-approved procedures keeps any remaining coverage intact. We are an independent Gelco service provider, not affiliated with or authorized by Gelco, and we document every part number and procedure for your records. Call (571) 489-4365 if you want us to review your warranty status before scheduling.
Common Gelco parts - pilot assemblies, thermopiles, refractory panels - ship within three to five business days from our distributors. We stock universal-fit equivalents for emergency heat-restoration calls, but we prefer to match OEM spec when the homeowner plans to stay in the house long-term. If your Gelco unit is down during a cold snap, we’ll tell you honestly whether the temporary fix can hold until the factory part arrives.
Repair if the firebox and venting are sound and the unit heats the space efficiently. Replace if the heat exchanger is cracked, the flue liner is incompatible with current code, or repair costs exceed 60% of a new insert. We make this call with camera evidence you can see, not a sales pitch. Some Falls Church homeowners with 1990s Gelco wood-burning inserts choose to convert to gas - we handle that too, with upfront pricing for both paths.
Gas Gelco fireplaces need annual inspection and cleaning of the burner, pilot, and vent termination. Wood-burning Gelco inserts and fireplaces need yearly sweeping if used as a primary heat source, every two years if occasional. Falls Church’s oak-heavy firewood and freeze-thaw cycles accelerate creosote buildup and masonry stress. Skip it, and you’re gambling with chimney fire risk and carbon monoxide intrusion. The $89 Seasonal Tune-Up catches problems before they become expensive.
Most weeks, yes - we schedule Gelco fireplace services within three to five business days during peak season (October through February), faster in shoulder months. We do not promise same-day dispatch because we won’t send a technician to rush a diagnosis. A live person answers 24/7 to book your slot and advise if your situation needs immediate attention. Call (571) 489-4365 for the next available opening.
