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 Damper Repair: The Ashburn Owner’s Guide
A Famco damper repair in Ashburn, VA typically runs $285 to $540 installed, depending on the model and what actually failed. We stock Famco-compatible repair kits on the truck, so most jobs are done in one visit, usually within 60 to 90 minutes. Most homeowners find out their damper failed on a cold morning when the fireplace room smells like a campfire, or during an inspection when the camera shows a damper blade that hasn’t seated right in years.
Here’s the thing about Famco dampers: the brand earned its name building simple, cast-iron top-sealing dampers that outlast a lot of chimneys. But simple doesn’t mean forever. The cable stretches. The bracket rusts. The blade warps from heat cycles. And when any one of those happens in Ashburn’s humid summers and freeze-thaw winters, the damper either won’t open, won’t close, or leaks air you’re paying to heat or cool.
We’ve repaired enough Famco units in Ashburn to know the failure patterns before we even open the firebox. Corrine Halstead, our owner, put it plainly after a run of One Loudoun jobs where the builders spec’d Famco across entire streets: “The camera doesn’t guess. Neither do we.” We’ll match the part, quote a written price before touching anything, and document it all with photos before and after.
Which Famco Models This Applies To
Famco makes two damper families we see most often in Ashburn: the top-sealing dampers (the round or square cast-aluminum units that sit at the top of the flue, pulled open and closed by a cable and handle assembly down at the firebox) and the throat dampers (the cast-iron or steel plate just above the firebox, often with a rotary or poker-arm control). The repair path differs significantly between the two.
The top-sealing units are the ones most Ashburn homes built after 2000 have. Famco’s TS series uses a stainless steel cable that runs down the flue to a handle mounted in the firebox wall. The failure point is almost always that cable: it frays at the pulley, kinks inside the conduit, or pulls loose from the crimp at the damper bracket. When that happens, the damper won’t fully open, or it springs shut on its own. We fix this with a cable-and-bracket repair kit sized to the flue diameter, then tension it to Famco’s spec.
The LD and LDS series throat dampers are simpler: a cast plate on a hinge, controlled by a gearbox or worm-drive handle. Failures here are usually a stripped gear, a rusted hinge pin, or a blade that’s warped enough that it won’t seal. The repair can sometimes be a gear replacement only, which is cheaper than a full damper swap.
Compatibility gotcha worth knowing: Famco top-sealing dampers are sized by inside flue tile dimensions, not by firebox width. We’ve had Ashburn homeowners order the wrong part online by measuring the firebox opening and guessing. The right part depends on the flue’s actual interior measurement, and the mounting brackets are specific to whether you have a clay tile flue or a metal liner. If you’re not sure which you have, that’s exactly what the camera inspection settles before any work is quoted.
On OEM versus aftermarket: Famco’s repair kits are well made and reasonably priced for what they are. There are generic aftermarket cables and brackets floating around online. We’ve installed both. The generic cables are thinner and stretch faster, especially in Ashburn’s temperature swings, so we no longer install them. We’ll use OEM Famco repair components, and when a part is discontinued, we’ll tell you and match a Copperfield or Gelco equivalent that’s actually rated for the same duty. We source through Haven’s buying network, which keeps the pricing honest on our end. Level Two Chimney Ashburn is an independent service provider, not affiliated with Famco.
Signs Your Famco Damper Repair Is Failing
- You smell smoke or soot in the room when the fireplace isn’t in use. The damper blade isn’t seating fully, and flue gases from the last fire are finding their way back down. On a top-sealing Famco, this usually means the cable lost tension and the blade is resting slightly open.
- The handle feels loose, spins freely, or has no resistance. That resistance is the cable pulling the damper blade against its spring. No resistance means the cable snapped at the crimp or the blade is stuck open. Either way, the damper isn’t doing its job.
- Cold air pours into the room in winter, or hot air in summer. A properly sealed Famco damper blocks the flue like a plug. When that seal fails, your HVAC is effectively running with a window open in the chimney. In Ashburn, with our winter lows and summer highs, this shows up on the energy bill before anything else.
- You hear a metallic scraping or grinding when you work the handle. That’s the cable rubbing against a kinked conduit, or a throat damper gear that’s chewing itself apart. It only gets worse with use.
- The handle moves but the damper doesn’t seem to open. On a throat damper, this is usually a stripped worm gear. On a top-sealing model, the cable is off its pulley at the top and moving the handle just coils slack in the conduit. The fire will struggle to draft, and smoke will roll back into the room.
None of these fix themselves. A failing damper gets more expensive the longer it runs, because a partially open flue pulls moisture into the chimney, and that moisture attacks mortar joints and the liner. In Ashburn, where spring rains and humid summers are the norm, a stuck-open damper accelerates spalling in the flue tile.
BeforeAfterReplacement Cost & What’s Included
For Famco damper repair in Ashburn, you’re looking at $285 to $540 installed, depending on what failed and which Famco model you have. A cable-and-bracket repair kit on a top-sealing unit is typically $285 to $385. A full damper assembly replacement, or a throat damper gearbox rebuild, lands in the $420 to $540 range. If the flue needs the old damper mounting hardware extracted and the seat cleaned to bare metal, that’s included in the price, not billed as a separate line item.
Every price we quote is written, itemized, and delivered before any work starts. You’ll see the part cost, the labor, and the warranty in black and white. That’s Clause 1 of the Haven Standard, and it’s been our practice since Level Two started in 2009. The warranty on a Famco repair is one year on parts and labor, backed by our 365-Day Done Right Promise: if it’s not done right, we make it right.
You also walk away with a documented photo record of the repair, including before and after shots of the damper and cable. We’ve been doing that on every job since 2009, long before it became an industry talking point. It matters because you should be able to see exactly what was replaced and how it sits in the flue. If you bring us a competitor’s written quote for the same Famco repair, we’ll do a free second opinion on the scope, no charge.
DIY or Call Us?
What you can safely check yourself: whether the handle moves freely, whether the damper visibly opens and closes, and whether you can see daylight through the flue from the firebox. On a top-sealing Famco, look up from inside the firebox with a flashlight. If the blade is cracked, visibly off its track, or the cable has slack, that’s enough to know it needs attention.
What you shouldn’t do yourself: replace the cable or the blade. The working end of a top-sealing damper is at the top of the flue, reached from the roof. That means ladder work on an Ashburn roof pitch, often with a tile or composite surface, and the cable runs through a conduit you can’t see into. Tensioning the cable wrong is the most common cause of a repeat failure within six months. And if you drop a bracket or tool down the flue, you’ve turned a damper repair into a flue extraction at best, and a cracked flue tile at worst. We’ve got the harnesses, the high-temp silicone, and the tensioning tools on the truck. The repair is quick for us because we do it every week in Ashburn.
If you’ve read this far, you’re probably past the “maybe I’ll try it” stage. Call us at (240) 220-9412. We’ll schedule a visit, camera the flue, and give you a written price before anything comes off the truck.
FAQs
A Famco top-sealing damper in Ashburn typically lasts 10 to 15 years before the cable, bracket, or blade needs repair. Ashburn’s humid summers and winter temperature swings shorten that lifespan compared to drier climates, because the spring and crimp points see more thermal cycling and moisture exposure. Regular sweeps that include damper inspection will catch wear before a failure leaves you paying to heat a leaky flue. If yours is past the decade mark and the handle feels loose, it’s worth a camera look. Call (240) 220-9412 and we’ll put eyes on it.
Most of the time, yes. We repair Famco dampers far more often than we replace them. Cable replacement, bracket re-seating, gear swaps on throat dampers, and blade re-alignment cover the majority of what we see. The camera tells us which path applies to your exact unit before we quote a dollar amount. Replacement only makes sense when the blade is cracked through or the frame is warped past a usable seal. Call (240) 220-9412 for a written assessment.
Most Famco damper repairs in Ashburn are completed in 60 to 90 minutes on site. The exception is a full damper assembly replacement, which runs slightly longer because the old mounting hardware needs extraction and the flue seat needs cleaning before the new unit mounts. Either way, it’s a one-visit job in nearly every case. We’ll text you when the technician is on the way, and you’ll have the photo record before we leave.
Yes. Our Ashburn trucks carry Famco-compatible cable kits, brackets, springs, and gear components for the models we see most often in the area. That means most repairs are quoted, approved, and finished in one appointment. We also stock equivalent parts from Copperfield and Gelco for situations where a Famco component has been discontinued or a different match is more durable. Call (240) 220-9412 and we’ll tell you over the phone whether your model is one we typically carry parts for.
