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.
Famco Chimney Liner & Rebuild in Manassas: What to Know First
We provide independent Famco chimney liner and rebuild service in Manassas, with most liner replacements and partial rebuilds completed in a single visit and priced upfront before any work begins. A typical Famco stainless steel liner replacement runs $2,800 to $4,500 depending on flue length and accessibility, and we’ll tell you honestly whether your existing liner can be repaired or truly needs replacing. This page is for Manassas homeowners who have a Famco liner or rebuild component in their chimney system and want a technician who knows the difference between Famco’s 316Ti flexible liner and their rigid 304 series without learning it on your job. Call (571) 586-0593 anytime - a live person answers, even at midnight on a Sunday.
How Famco Products Fail - and How We Fix Them
- Famco 316Ti flexible liner fatigue in tall Manassas flues. The 316Ti alloy handles acidic condensate well, but in the 25-foot-plus flues common in Manassas Park split-levels and Lake Jackson colonial revivals, the corrugations work-harden at stress points where the liner bends to offset the chimney throat. We’ve replaced dozens where the crown penetration point cracked after eight to twelve years, not the twenty the brochure suggests. We sleeve with a new 316Ti section or, if the damage is extensive, pull a fresh run with reinforced collar support at the top.
- Famco rigid 304 liner joint separation in exterior chimneys. The 304 rigid line uses twist-lock couplings that seal with a high-temp gasket. On north-facing exterior chimneys in Manassas - and we see this near the battlefield area and along Sudley Road - freeze-thaw cycling loosens the male-female joint enough that combustion gases leak into the masonry cavity. Our fix: disassemble to the sound joint, replace with OEM Famco couplings or a welded sleeve if the gap has ovalized, and reseal with ceramic rope rated to 2,100°F.
- Famco top-sealing damper corrosion binding the liner. The Famco Sealtight damper integrates with some liner systems, and when the cast-aluminum frame corrodes at the pivot, the damper plate drops into the flue throat and scores the liner wall on opening. We see this in homes within two miles of Bull Run where humidity stays high through October. We extract the damaged damper, assess the liner scoring, and either polish out light damage or replace the section if the wall thickness is compromised.
- Famco smooth-wall liner creosote bridging in slow-burning fireplaces. The reduced corrugation on Famco smooth-wall liners was designed to improve draft, but in Manassas homes where owners burn seasoned hardwood at low air settings for overnight heat, the near-smooth surface lets glaze creosote form continuous sheets instead of breaking up. This restricts draft and accelerates acid condensation at the top. We mechanical-brush to bare metal, then switch the homeowner to a hotter burn protocol or recommend a stainless upgrade if the pattern repeats.
- Famco rebuild collar mortar failure at the chimney shoulder. Famco’s rebuild collars are solid steel, but the refractory mortar bed they sit in cracks when the surrounding brick expands at a different rate - standard in Manassas clay-brick construction from the 1970s and 1980s. Water enters, rusts the collar skirt, and the liner loses its dead-load support. We cut back to sound brick, repoint with Type N lime mortar matched to the existing modulus, and reset the collar on a bed of ceramic fiber board that absorbs differential movement.
Our Famco Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, asks what you’re seeing or smelling, and books a Level-2 camera inspection. No deposit, no pressure.
- 2
Inspection with documentation. Our tech runs a camera the full flue length, photographs every joint, collar, and liner wall section. You see the images on a tablet while we explain what we’re looking at. Russell Haines trained our senior techs personally on Famco-specific wear patterns, and 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.
- 3
Parts decision: OEM Famco or quality equivalent. If Famco OEM is available with reasonable lead time, we quote it. If your liner is discontinued or the job needs faster turnaround, we specify DuraFlex, Gelco, or HeatShield equivalents that meet or exceed Famco’s original ratings - never builder-grade substitutes. You choose.
- 4
Repair with single-visit completion. Our background-checked, uniformed techs arrive with the agreed parts and tools. Most Famco liner replacements and partial rebuilds finish in one day. We protect floors and furniture, and we clean up behind ourselves.
- 5
Post-repair test and photo report. We run a smoke test or draft gauge check, depending on the repair type, then email you the before-and-after photos with a plain-English summary.
- 6
The 90-Day Done Right Promise. Your invoice includes our guarantee in writing: if it’s not right, we make it right. No paperwork to find, no arguing. That’s the Keystone Standard we’ve operated under since 1984.

Why Manassas Homeowners Call Hearthstone Chimney Co. for Famco Work
Manassas homeowners have called us for over 42 years because we document what we find, explain it in plain English, and stand behind the repair. Our 90-Day Done Right Promise is in writing with no arguing. Our techs know Famco products specifically - not just “stainless liners” generally - and when Famco OEM isn’t the right call, we carry DuraFlex, HeatShield, and Gelco alternatives that meet the same spec. We’re not a chain sending whoever’s available that day. We’re not a one-truck operator who might answer the phone next year. We’re Hearthstone Chimney Co., and we’ll be there when we say.
FAQs
Famco’s original equipment warranty covers manufacturing defects regardless of who installs it, but improper installation voids coverage. As an independent Famco service provider, we document every step with photos and follow Famco’s published installation clearances so your warranty position stays clean. Call (571) 586-0593 and we’ll review your specific Famco model’s warranty terms before we book.
We source Famco OEM when it’s available and appropriate for the repair. When Famco has discontinued a liner series or when lead time would leave you without heat, we specify DuraFlex, Gelco, or HeatShield equivalents with equal or better temperature and corrosion ratings - never unbranded imports. You’ll know exactly what’s going in your chimney before we start.
A Level-2 camera inspection tells the story. Localized damage - one bad joint, a collar leak, surface scoring under a damper - often repairs cleanly. Widespread wall thinning, multiple seam failures, or a liner pulled out of round by settling masonry usually means replacement. We show you the camera footage and give you both options when they exist, with our honest recommendation and no pressure either way. Call (571) 586-0593 to schedule.
Most single-flue Famco liner replacements in Manassas homes finish in one day, start to finish. Complex jobs - tall flues with multiple offsets, or liner replacement bundled with a partial rebuild - may run into a second day. We tell you the expected duration in your upfront estimate so you can plan.
A damaged liner lets combustion gases, including carbon monoxide, leak into living spaces through masonry cracks. It also allows creosote to accumulate in hidden voids where it can ignite. The risk is real and specific, not theoretical, but we don’t scare-sell: some Famco issues we’ve inspected in Manassas were genuinely fine to defer a season, and we said so. Others needed immediate attention, and we said that too. The only way to know is to look. Call (571) 586-0593 for a free camera inspection.
