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 Cap Installation: The Smithtown Owner’s Guide
We stock and install Famco-compatible chimney caps across Smithtown, with most replacements running between $340 and $620 installed depending on flue size and whether the crown needs attention first. If your cap is rusted through, blown off in a nor’easter, or letting water past the mesh, we can usually get eyes on it and give you a firm price the same day you call. Homeowners near Caleb Smith State Park Preserve and throughout the older Smithtown neighborhoods tend to notice the problem first when they see rust streaks on the brick or smell damp ash during a humid July.
Which Famco Models This Applies To
Famco builds caps across several series, and the right match depends on whether you have a single-flue model like the Wind Directional or a multi-flue cap spanning the entire crown. Most Smithtown homes we see carry the single-flue galvanized or stainless units in 8×8, 8×13, or 13×13 inch sizes, though the Wind Directional line also comes in 8×17 for larger boiler flues common in the 1970s splits near Hauppauge Road.
Here’s how to identify yours before we arrive. Look for a stamped model number on the underside of the lid or on the vertical mesh band, usually starting with “FAM-” followed by the series code. If the tag is rusted away, measure the outside dimensions of your flue tile, not the old cap itself, worn caps often sag and give a false reading. We carry both OEM Famco and quality aftermarket equivalents from Gelco and Olympia Chimney on our trucks, the aftermarket units match the 304 stainless spec and save roughly $40-$80 on parts without the branding markup. Hearthstone Chimney Co. is an independent service provider, not affiliated with Famco, so we pick the part that fits your flue correctly rather than pushing a particular badge.
Signs Your Famco Chimney Cap Is Failing
- Rust bleeding down the chimney face. Famco’s galvanized caps carry a 20-year finish warranty in dry climates, but Long Island’s salt air and freeze-thaw cycling cut that roughly in half. Once the galvanizing cracks at the seam, the steel underneath weeps orange streaks that stain mortar joints permanently if you let it go.
- Mesh sides pulled away from the frame or clogged solid with creosote flakes. The spark arrestor mesh on older Famco units is spot-welded at the corners, and after a decade of thermal cycling those welds fatigue. A separated mesh won’t stop embers, and a clogged mesh starves the fire of makeup air, sending smoke into the living room.
- Cap sitting crooked or missing entirely after a windstorm. Famco’s Wind Directional caps rely on a snug friction fit over the flue tile, but the constant southwest winds off the Nissequogue River gradually work them loose. We’ve recovered caps from gutters, lawns, and once from a neighbor’s hydrangea bed on Edgewood Avenue.
- Water in the firebox or white efflorescence blooming on the back wall. A cap with a cracked lid or failed storm collar lets rain run straight down the flue. In Smithtown’s older colonials with shallow fireboxes, that water pools behind the damper and leaches lime out of the brick, leaving the white powdery bloom that homeowners often mistake for mold.
- Animals or nesting debris visible from below. Squirrels chew through weakened mesh in late fall, and starlings pack twigs into any gap larger than three-quarters of an inch. If you’re hearing scratching in February or pulling nest material out with the poker, your cap’s integrity is already compromised.
Replacement Cost & What’s Included
| Service | Typical Range |
|---|---|
| Famco-compatible cap, standard single-flue (galvanized) | $340 - $440 |
| Famco-compatible cap, single-flue (304 stainless) | $420 - $520 |
| Multi-flue cap spanning full crown | $520 - $620 |
| Crown wash / minor masonry prep if needed | $80 - $180 additional |
The price spread depends on three things: whether we can reuse your existing storm collar, whether the flue tile itself is cracked and needs stabilization first, and whether your roof pitch requires us to set up on the high side. We give you the full number before we climb, and that’s the number on the invoice. Every cap installation includes a Level-2 camera inspection of the flue above the smoke chamber, photos you can see, a plain-English verdict, and our 90-Day Done Right Promise in writing. If it leaks, rattles, or doesn’t sit square, we come back. No paperwork, no arguing.
DIY or Call Us?
There’s an honest line here. A homeowner with a stable ladder, a helper, and a flue that measures true to standard size can physically swap a friction-fit cap. What we’ve learned in twenty years across Suffolk County is that the measurement is where DIY goes wrong, an eighth-inch variance between the tile top and the cap skirt means a gap that lets in water or a fit so tight it cracks the flue lip when you tap it home. The roof pitch on most Smithtown colonials is steep enough that we don’t recommend anyone over sixty-five make the climb without proper fall protection. And if the crown beneath the cap is spalling or the flue tile is cracked, putting a new cap on top hides the real problem until it’s an expensive one. We’ll check the whole assembly, show you photos, and tell you straight if a cap is all you need or if there’s more to address. Call us at (631) 814-2057 and we’ll walk through what you’re seeing.
FAQs
A galvanized Famco cap typically gives 10 to 14 years on Long Island before the seams start weeping rust, while the 304 stainless units run 20 to 25 years if the crown beneath them drains properly. Salt air and the freeze-thaw cycles we get in January and February are the main accelerants. If you’re past year twelve on galvanized, it’s worth having us take a look during your next sweep.
Spot-welding mesh back on or patching a rust hole buys a year or two at most, and the repair never matches the original galvanizing or passivation, so the rust returns at the weld. We don’t do patch jobs because we’ve seen too many fail the winter after we leave. A proper replacement is the only fix we stand behind with the 90-Day Done Right Promise.
Most single-flue replacements take 45 minutes to an hour on the roof, plus another 20 minutes for the camera inspection and photo review with you inside. Multi-flue caps or jobs needing crown prep run closer to two hours. We complete most jobs in a single visit, and we don’t leave until you’ve seen the photos and signed off on the work.
We carry Famco-compatible single-flue caps in 8×8, 8×13, 13×13, and 8×17 on every service vehicle, plus multi-flue sizes up to 17×21. If you have an unusual flue dimension or a custom wind directional from the 1990s, we may need a day to pull from our Smithtown warehouse or order direct. Call (631) 814-2057 with your model number or measurements and we’ll confirm before we roll.
