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.

AfterFamco Fireplace Services in Manassas: What to Know First
We provide independent Famco fireplace services in Manassas, from gas valve troubleshooting to firebox rebuilds, with most repairs completed in a single visit and upfront pricing agreed before we start. Typical turnaround is a few days for standard calls, faster when a burner assembly or pilot issue leaves you without heat. We’re not the cheapest option in Prince William County, and we don’t try to be - we charge for the repair done right, documented with photos you can see, and backed by our 90-Day Done Right Promise in writing.
This page is for Famco owners in Manassas, Bristow, and the surrounding areas who need their fireplace working reliably and want a technician who knows the difference between a Famco FMI direct-vent insert and a B-vent gas log set without reading the manual on your porch. If your pilot won’t stay lit, your remote isn’t talking to the receiver, or you’re smelling gas near the hearth, call (571) 586-0593. A live person answers, 24 hours a day.

How Famco Products Fail - and How We Fix Them
- FMI direct-vent inserts: pilot dropout in Manassas wind. The FMI 42-inch and 36-inch direct-vent inserts use a sealed combustion system that works fine until the west wind off the Bull Run Mountains hits the termination cap at the wrong angle. The pilot flame lifts, the safety thermocouple cools, and the homeowner gets intermittent heat or none at all. We see this in the Sudley and Yorkshire neighborhoods every February. Our fix: we check cap orientation and clearance first, then replace the thermopile or pilot assembly with OEM or a tested aftermarket equivalent, and we test under actual draft conditions before we leave.
- FMI B-vent gas log sets: cracked ember beds and degraded burner ports. The ceramic fiber ember bed in older FMI B-vent units (common in 1990s Manassas split-levels) degrades after 8-12 seasons of use. Homeowners notice yellow, sooty flames where they once had blue. We replace the ember bed and inspect the burner manifold for corrosion - a $45 part that prevents a $400 burner replacement six months later. We stock the common FMI ember bed configurations on our trucks.
- Famco chimney caps: galvanized collar rust-through. Famco’s standard galvanized chimney caps, installed by many Manassas builders in the 2000s, develop collar rust where the cap meets the flue tile. Water drips onto the smoke shelf, then into the firebox. We replace with a Gelco or Copperfield stainless cap with a wider flange, or a custom-fabricated unit for oversized flues in the historic homes near Old Town Manassas. The new cap outlasts the original by a decade or more.
- FMI fireplace doors: tempered glass stress fractures. The tempered glass panels on FMI factory-built door assemblies fracture in a characteristic pattern - a single impact point radiating spider cracks - usually from closing the door on a half-burned log or from thermal shock when cold glass meets a hot fire. We measure for exact replacement glass or source a compatible door assembly when the frame has warped from repeated overheating.
- Famco dampers: stuck or missing seals in pre-2010 units. The cast iron throat dampers in Famco wood-burning fireplaces installed before 2010 lose their fiberglass rope seal, bleed conditioned air up the flue year-round, and stick open or closed from creosote glazing. In Manassas, where summer humidity swells the chimney draft, a stuck-open damper costs more in HVAC waste than most owners realize. We clean the damper seat, replace the seal, or install a top-sealing damper from Gelco when the throat mechanism is too far gone.
Our Famco Fireplace Services Process
- 1
Call and schedule. A live person answers, asks what you’re seeing or smelling, and books a window that works for you. We don’t use callback apps or scheduling bots.
- 2
Arrival and diagnosis. Our technician arrives in a marked truck, uniformed, and starts with a visual inspection and combustion test. For gas units, we check manifold pressure with a digital manometer - not guesswork. For wood units, we run a Level-2 camera inspection up the flue.
- 3
Photos and plain-English verdict. You see what we see. If the flue liner is cracked, we show you the crack. If the gas valve is failing, we explain why replacement beats repair. Russell Haines trains every technician to read a flue honestly - if the flue is clear and the mortar is solid, we’ll tell you that. If it isn’t, we’ll tell you that too.
- 4
Parts decision and upfront pricing. We stock common Famco parts - pilot assemblies, thermopiles, ember beds, door glass - and carry DuraFlex, HeatShield, and Gelco materials for related chimney work. If we need to order an OEM Famco component, we tell you the lead time and quote the exact price before you approve the job. The number on the estimate is the number on the invoice.
- 5
Repair, test, and document. We complete the repair, run the unit through its full cycle, check CO levels at the fireplace face and in the room, and photograph the completed work. Most Famco jobs finish in one visit.
- 6
Written guarantee and cleanup. You get a copy of our 90-Day Done Right Promise, the inspection photos on request, and a work area left cleaner than we found it. If something isn’t right, we come back. No paperwork to file, no arguing.

Why Manassas Homeowners Call Hearthstone Chimney Co. for Famco Work
We’ve been answering the phone with a live person for over 42 years, and we plan to be in Prince William County for thirty more. That changes how we treat every job. Our 90-Day Done Right Promise is in writing, not a verbal maybe. Our technicians are background-checked, uniformed, and trained on Famco’s specific failure modes - not generic gas appliance repair.
We also work with DuraFlex, HeatShield, and Gelco materials, which matters when your Famco fireplace needs chimney work too. A technician who knows only the hearth box and not the flue above it is only half qualified. We document every inspection with photos and a plain-English verdict, and we back every job with the K.E.Y.S. values code: Krafted right, Every time, Your home first, Standing behind it.
Done right - and we stand behind it.
FAQs
No, using an independent Famco service provider like Hearthstone Chimney Co. does not automatically void your warranty, provided the work is performed competently and documented. Famco’s warranty covers manufacturing defects, not installation or service by unaffiliated technicians. We use OEM or equivalent-quality parts and document our work, so your warranty rights remain intact for valid claims. If your unit is still under factory warranty, we’ll note that in our report and advise whether the issue is a warranty matter or wear-and-tear. Call (571) 586-0593 for a free estimate.
Most common Famco parts - pilot assemblies, thermopiles, ember beds, door glass - are on our trucks or available within 2-3 business days from regional distributors. Discontinued FMI series components may take 5-10 business days if we need to source from specialty suppliers or fabricate a compatible solution. We always tell you the lead time before you approve the work, and we don’t charge storage or delay fees. Call (571) 586-0593 to check availability for your specific model.
Repair is usually the better value if the firebox and flue are sound, the unit is under 20 years old, and the repair cost is under half the price of a comparable new installation. We see many Famco units in Manassas - especially the FMI direct-vent inserts from the early 2000s - with another decade of life left if the gas valve or burner is addressed. We only recommend replacement when the firebox is cracked, the flue is compromised, or repair costs approach replacement price. Our camera inspection gives you the facts to decide. Call (571) 586-0593 for an exact quote - estimates are free.
A Famco gas fireplace should be inspected and tuned annually, even if it appears to work fine. Manassas’s hard water and seasonal humidity accelerate corrosion in pilot orifices and valve components, and debris from nearby trees can block vent terminations. An annual check catches $45 problems before they become $450 problems. We offer our $89 Seasonal Tune-Up each fall, and seniors and veterans save an additional 5% year-round. Call (571) 586-0593 to schedule.
Skipping service on a Famco wood-burning fireplace leads to creosote buildup, which increases chimney fire risk and can crack the flue liner, allowing carbon monoxide into living spaces. In Manassas, where many Famco units sit in original 1970s and 1980s chimneys, the combination of aged terra cotta flue tiles and neglected cleaning is a genuine hazard. We don’t scare-sell - we’ve simply seen the aftermath. A Level-2 camera inspection tells you exactly where you stand. Call (571) 586-0593 for a free estimate.
Ready to get your Famco fireplace working right? Call (571) 586-0593 today. A live person will answer, 24 hours a day, and we’ll schedule your free estimate at a time that works for you. Most repairs are completed in a single visit, with upfront pricing and our 90-Day Done Right Promise in writing.
