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 Puyallup Owner’s Guide
Famco damper repair in Puyallup 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 repair on the first visit. Most Puyallup homeowners discover the problem when smoke rolls back into the living room on the first cold night, or when they can’t get the damper to open at all after a summer of disuse.
In the South Hill corridor and the older neighborhoods near downtown Puyallup, we see a lot of Famco throat dampers that have been in service since the 1990s. The cast iron holds up, but the hinge pins corrode and the plates warp from years of uneven heating. Corrine Halstead and our crew run the camera first to confirm the flue condition, then write the price before touching a tool.
Which Famco Models This Applies To
Famco manufactured several damper lines over the decades, and the part you need depends on the throat size and mounting style. The most common in Puyallup homes are the Famco cast-iron throat dampers in 8″, 10″, and 12″ round flues, plus the rectangular models sized for Rumford-style fireplaces. Check the damper frame for a stamped model number near the hinge side, or measure the throat opening width and depth at the narrowest point.
Here’s where owners get tripped up: Famco used two different hinge pin diameters across production runs. The earlier 1980s-1990s dampers take a 3/8″ pin; later models switched to 7/16″. A mismatched replacement kit will install but won’t seat properly, leaving a gap that leaks heat and draws cold air year-round. We carry both specs in our Haven Standard parts inventory, sourced through Famco’s distribution network and quality aftermarket equivalents from Gelco and Olympia Chimney.
OEM Famco parts are still available for most common sizes, though lead times can stretch to two weeks for older rectangular models. Aftermarket equivalents from Gelco meet the same ASTM standards and carry equivalent warranties, usually at lower cost. We quote both options in writing before ordering anything.
Signs Your Famco Damper Repair Is Failing

- Smoke backdraft on startup. The damper plate isn’t sealing tightly against the frame, or it’s stuck partially closed. Cold air sinks down the flue overnight and creates a pressure block; smoke follows the path of least resistance back into your room.
- Rust flakes or debris falling into the firebox. The cast iron is degrading, or the galvanized frame is corroding from condensation. In Puyallup’s wet winters, we see accelerated rust where the damper sits below the roofline in homes without proper chimney caps.
- The handle operates but the plate doesn’t move. The linkage between the handle and the plate has separated, or the hinge pin has sheared. This is common in Famco dampers after 15-20 years of seasonal cycling.
- Visible gaps around the plate when closed. Warping from overheated fires or gradual metal fatigue. Even a 1/4″ gap bleeds significant heated air up the flue 24 hours a day.
- Damper stuck fully open or fully closed. Creosote buildup has glued the plate to the frame, or the pivot mechanism has seized. We see this in Puyallup homes where the chimney hasn’t been swept in three or more seasons, especially with frequent green-wood burning.

AfterReplacement Cost & What’s Included
| Repair Type | Typical Range in Puyallup |
|---|---|
| Damper plate replacement (same frame) | $280-$380 |
| Full damper assembly (plate + frame) | $420-$520 |
| Handle/linkage repair only | $180-$260 |
| Chimney sweep + damper service bundle | $340-$440 |
The range depends on three things: whether we can reuse the existing frame, whether the firebrick or smoke chamber needs repair to access the damper, and whether you choose OEM Famco or a Gelco aftermarket equivalent. Every quote includes the NFPA 211 Level 2 camera inspection, a written scope, and the documented photo record required by Clause 4 of the Haven Standard.
Our 365-Day Done Right Promise covers the installation and the part. If the new damper doesn’t seal properly or the handle binds, we return and make it right at no charge. Materials come through our Haven buying network, which includes Famco, Gelco, and Olympia Chimney, specifically to keep customer prices honest.
DIY or Call Us?

There’s a safe middle ground here. You can check whether the handle moves freely and whether the plate responds. Shine a flashlight up the flue from the firebox and look for obvious gaps, rust holes, or a plate that’s clearly off its pivot. What you cannot safely do is reach up past the smoke shelf to manipulate a 12-pound cast-iron plate while standing on a hearth, or attempt to remove the frame without supporting the masonry above it.
The real risk isn’t the part itself. It’s what you discover once you’re in there. We’ve found deteriorated smoke chambers, cracked flue liners, and Class III glazed creosote behind dampers that looked simple from below. Camera goes in first. Price gets written down second. Work starts third. If you’re seeing symptoms, call (253) 323-5667 and we’ll scope it properly.
FAQs
A cast-iron Famco throat damper typically lasts 20-30 years in Western Washington, though we see premature failure around 12-15 years in homes that burn unseasoned wood or lack a rain cap. The wet winters and marine air accelerate corrosion on the hinge pins and frame. Annual sweeping extends the service life significantly. Call (253) 323-5667 for an exact quote - estimates are free.
Sometimes. A separated handle linkage or a loose set screw is a straightforward fix. But a warped plate, cracked frame, or corroded hinge pin requires full replacement - the cast iron can’t be machined or welded reliably in place. We only recommend replacement when the camera shows the damage and you see the photo evidence yourself. Call (253) 323-5667 for an exact quote - estimates are free.
Most Famco damper replacements take 90 minutes to two hours, assuming the flue is clear and the smoke chamber doesn’t need repair. We book a half-day window so we’re not rushing the inspection or the documentation. You’ll get the written warranty and photo record before we leave. Call (253) 323-5667 for an exact quote - estimates are free.
We carry the most common Famco-compatible throat dampers in 8″, 10″, and 12″ round, plus rectangular sizes for standard Rumford openings. Both 3/8″ and 7/16″ hinge pin specs are on the shelf. For rare or obsolete Famco models, we can source through our Haven buying network, usually within two business days. Call (253) 323-5667 for an exact quote - estimates are free.
