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 Haverhill Owner’s Guide
Famco damper repair in Haverhill 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 trucks and can usually complete the swap in a single visit. Most Haverhill homeowners discover the problem on the first cold night in October or November, when they open the damper and it won’t seal, won’t stay open, or drops a rust flake into the firebox.
Which Famco Models This Applies To
Famco manufactures throat dampers, top-sealing dampers, and fireplace smoke chamber dampers across several product lines. The most common units we see in Haverhill are the Famco throat damper series with 24-inch, 30-inch, and 36-inch plate widths, and the Famco top-sealing damper line that mounts to the crown with a cable running down the flue. The throat dampers typically carry a stamped model number on the steel frame rail, visible with a flashlight looking up from the firebox. Top-sealing units have a cast-aluminum cap with a Famco logo and size marking.
We source Famco parts through our Haven buying network, along with DuraFlex, HeatShield, and Gelco materials. For discontinued Famco models, we match spec with quality aftermarket equivalents that maintain the same plate thickness (typically 3/16-inch steel for throat dampers) and frame width. One compatibility gotcha: Famco’s 30-inch throat damper from the 2005-2012 production run used a non-standard 5/16-inch pivot pin, so a generic replacement plate won’t seat without bushing work. We check that before quoting.

Signs Your Famco Damper Repair Is Failing

- The handle turns but the plate doesn’t move. The linkage between the handle spindle and the damper plate has separated, usually at the cotter pin or rivet point. On Famco throat dampers, this linkage sits in a narrow frame channel where creosote hardens and jams the joint.
- The plate is stuck open or stuck closed. Rust scaling builds on the frame rails, especially in Haverhill’s older brick chimneys where flue gases cool quickly and condense. A stuck-closed damper means you can’t use the fireplace. A stuck-open damper means heated air escapes 24/7.
- You feel a cold draft even when the damper is “closed.” The steel plate has warped from heat cycling or the frame seal has corroded. Famco plates are solid steel, but after 15-20 years of Massachusetts freeze-thaw cycles, they bow enough to leak.
- Rust particles or flakes fall into the firebox. Surface rust advances to flaking, which means the plate thickness is compromised. We measure remaining thickness with a caliper; below 1/8 inch, replacement is the only sound option.
- The cable on a top-sealing Famco won’t retract fully. The stainless cable frays at the cap pulley or the spring tensioner weakens. Haverhill’s coastal-influenced humidity accelerates cable corrosion even inside the flue.

The range reflects access difficulty. A throat damper in a standard Rumford-style firebox with a clean smoke chamber is straightforward. A damper tucked behind a heatilator or in a narrow flue on one of the older colonials near Washington Square takes longer to reach safely. Every quote is written before work starts, with parts and labor itemized. The 365-Day Done Right Promise covers the installation. We also warranty the part itself against manufacturer defect.
DIY or Call Us?

There’s a safe middle ground and a hard stop. A homeowner can verify the model number, measure the plate width with a tape measure, and check whether the handle turns freely. That’s useful information if you call us.
What you shouldn’t do: try to force a stuck plate with a pry bar, or attempt to remove a rusted frame from the mortar joints. Throat dampers sit in high-heat mortar beds that can crack and drop debris into the smoke chamber. The steel is heavy, the angles are awkward, and a slipped tool in a firebox risks liner damage. The camera doesn’t guess. Neither do I. We bring the inspection camera, document the frame condition, and quote the exact repair. Call (351) 444-9705 when you’re ready.
FAQs
A Famco steel throat damper typically lasts 15-25 years in Massachusetts, with the lower end more common in homes that burn green hardwood or let the fire smolder overnight. Haverhill’s freeze-thaw cycles and the acidic flue gas condensation in older unlined chimneys accelerate frame rail corrosion. Call (351) 444-9705 for an exact assessment of yours.
Sometimes. A separated linkage can be re-pinned, and minor surface rust can be cleaned and coated if the plate thickness is still within spec. We make that call only after the camera inspection, and we show you the footage. If the plate is warped or the frame is scaling, replacement is the honest recommendation. Estimates are free.
Most Famco damper replacements take 90 minutes to two hours from ladder set to cleanup. A full frame removal and re-bed in fresh refractory mortar adds 45 minutes. We schedule a morning or afternoon window, text when the tech is en route, and leave a documented photo record under Haven Standard Clause 4.
We carry Famco-compatible throat damper plates in 24-inch, 30-inch, and 36-inch widths, plus common frame assemblies and top-sealing caps. For less common sizes or discontinued models, we order through our Haven network and return within 48 hours. We don’t start the job until the correct part is in hand.
