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 Damper Repair: The Leominster Owner’s Guide
Famco damper repair in Leominster typically runs $280-$520 installed, depending on whether we’re replacing the plate, the frame, or the full assembly. We stock Famco-compatible parts on our Leominster service trucks and can usually match your model same-day. Most Leominster homeowners discover the problem on the first cold snap in October or November, when they open the damper and it sticks, drops halfway, or won’t seal at all.
Corrine Halstead and our crew have handled Famco dampers in Leominster homes for years, from the 1980s split-levels near North Leominster to the older Colonials around Monument Square where the flue liners tend to have stories of their own. The camera goes up first. Everything else follows the footage.
Which Famco Models This Applies To
Famco manufactured throat dampers and top-sealing dampers across several series, and the part you need depends on which type is in your flue. Throat dampers sit just above the firebox; top-sealing models mount at the chimney crown and use a cable or chain running down the flue. Check the damper frame for a stamped model number, usually on the handle side or the front lip of the plate. If the tag is rusted away, measure the throat opening width and depth, and note whether the handle is a poker-style rotary or a simple pull-loop.
We source Famco parts and quality aftermarket equivalents through Haven’s buying network. OEM Famco plates fit exactly but can take longer to procure; aftermarket units from Gelco or Olympia Chimney match the critical dimensions and carry the same warranty at a lower parts cost. In Leominster’s freeze-thaw climate, we see the most failures on Famco throat dampers installed before 2005, when the cast-iron frames were more prone to thermal cracking. We stock common 30-inch and 36-inch aftermarket plates on our trucks; odd sizes or top-sealing cable assemblies we can source within 24 hours.

Signs Your Famco Damper Repair Is Failing

- The handle turns but the plate doesn’t move. The linkage pin inside the frame has sheared or the gear teeth have stripped. This is common on Famco rotary mechanisms after 15+ years of thermal cycling. The plate may be stuck open, dumping heated air up the flue, or stuck closed, trapping smoke in the firebox.
- The plate drops open on its own after you close it. The counterbalance spring has lost tension or the pivot rod has worn oval. In Leominster, we see this accelerated by the heavy creosote buildup that comes from burning green hardwood, which gums up the pivot points.
- You feel cold air dropping down the flue even when the damper is “closed.” The plate has warped or the frame has cracked, leaving a gap. A standard sheet of paper slid under the closed plate will tell you if the seal is gone. That gap is money leaving your house all winter.
- The plate is visibly cracked or rusted through. Cast iron fatigues. Once the plate is compromised, it can’t be welded reliably, not at the temperatures a flue sees. Replacement is the only sound repair.
- The damper was forced open and now the handle is loose or bent. The frame ears or the handle bracket have distorted. Continuing to operate it risks dropping the plate into the firebox during a burn, which is a chimney fire hazard and a difficult retrieval.

AfterReplacement Cost & What’s Included
| Service | Price Range (Leominster) |
|---|---|
| Famco damper plate replacement (aftermarket, standard size) | $280-$380 |
| Famco damper plate replacement (OEM or odd size) | $340-$450 |
| Full damper frame and plate assembly | $420-$520 |
| Top-sealing damper cable/chain replacement | $380-$480 |
What drives the range: accessibility (throat dampers in tight fireboxes take longer), whether the frame must come out, and whether we need to cut and re-point surrounding brick. Every quote is itemized in writing before work starts, per Haven Standard Clause 1. The price includes the NFPA 211 Level 2 camera inspection to confirm the flue condition above the damper, a documented photo record under Clause 4, and our 365-Day Done Right Promise. Materials come from Famco, Gelco, Olympia Chimney, and other suppliers in Haven’s buying network, sourced specifically to keep customer prices honest.
DIY or Call Us?

There’s a safe middle ground here, and then there’s where DIY stops. You can verify the model number, measure the throat, and check the plate for visible cracks from the firebox side. You can also test the seal with that slip of paper. What you should not do is attempt to remove a stuck damper plate or frame yourself. The cast iron is heavy, the firebox opening is tight, and the surrounding brick is easy to chip. More critically, if the damper has been modified or is part of an older system with a transite flue, disturbing it can release hazardous material.
We bring the right extraction tools, the replacement part already on the truck, and the camera to inspect the flue above before we close up. For a Famco damper repair in Leominster, call (978) 481-2900. We’ll give you a written price before any work starts, and a photo record when it’s done.
FAQs
A cast-iron Famco throat damper typically lasts 20-30 years in central Massachusetts, though we’ve seen them fail at 12 years in homes that burn unseasoned wood or never get swept. The freeze-thaw cycling and acidic condensation in Leominster’s older, unlined chimneys accelerate frame corrosion. Call (978) 481-2900 for an exact quote - estimates are free.
Sometimes the linkage or handle can be adjusted or replaced without removing the frame, but a cracked plate or warped frame cannot be repaired to a safe, functional standard. We won’t recommend replacement without camera evidence you can see for yourself. Call (978) 481-2900 for an exact quote - estimates are free.
A standard Famco plate replacement takes 90 minutes to two hours, including the camera inspection and documentation. Full frame removal and replacement in a tight firebox can run three to four hours. We book by the job, not the clock, so the price we write is the price you pay.
We stock common 30-inch and 36-inch aftermarket plates that fit Famco frames, plus hardware kits for rotary and pull-loop mechanisms. OEM Famco parts and odd sizes we source through Haven’s buying network, usually within 24 hours. Call (978) 481-2900 and we’ll confirm compatibility before we dispatch.
