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 Freeport Owner’s Guide
We stock and install Famco-compatible chimney caps across Freeport, with most replacements running $280 to $520 installed depending on flue size and whether your crown needs sealing work. Our trucks carry the common Famco galvanized and stainless-steel sizes, so we can usually match your cap and have it on the same visit. Most Freeport homeowners discover their cap has failed after a heavy Nassau County nor’easter sends water down the flue, or when they spot rust streaks on the brickwork that weren’t there last season.
Which Famco Models This Applies To
Famco builds chimney caps in two main series that we see in Freeport: the standard galvanized line and the 304 stainless-steel line. The galvanized caps carry a model prefix that starts with “GC” followed by the flue dimension, while stainless models use “SC” - so an SC-813 is an 8″ x 13″ stainless cap. The critical detail is measuring your flue tile’s outside dimensions, not the chimney crown, because Famco caps seat on the tile itself with side-mount tension screws.
Here’s where owners get tripped up: Famco changed its tension-screw spacing around 2016. A cap from the older production run won’t seat properly on newer flue tile without adapter brackets, and vice versa. We carry both screw patterns on the truck. For the OEM-versus-aftermarket question, genuine Famco stainless holds up fine, but we’ve found that the aftermarket Gelco equivalent uses a heavier-gauge mesh that doesn’t clog with creosote as quickly in Freeport’s damp coastal air. We stock both and will show you the difference before you decide.
Signs Your Famco Chimney Cap Installation Is Failing
- Rust streaks running down the chimney face. Galvanized Famco caps begin losing their zinc coating after about 8 to 12 years in Freeport’s salt-air environment. Once the base metal is exposed, every rain accelerates the bleed, and those orange-brown trails are your warning that the cap’s structural integrity is compromised.
- Water in the firebox after storms. A properly seated Famco cap sheds water outward through its drip edge. When the mesh screen separates from the frame or the lid warps from heat cycling, water finds the gap and runs straight down your flue. In Freeport’s older homes near the Nautical Mile, we’ve seen this destroy damper assemblies in a single winter.
- Mesh screen pulling away from the frame. Famco caps use a crimped wire-to-frame joint that fatigues over thermal cycles. Once the gap opens wider than a pencil, embers can escape during a chimney fire, and squirrels will treat it as an invitation.
- Lid sitting crooked or blown off entirely. The Famco lid attaches with stainless screws through a central collar. After enough wind events, those screws wallow out or the collar cracks. We’ve retrieved Famco lids from Freeport backyards after March gales - always a sign the underlying cap body is fatigued too.
- Draft problems or smoke backup. When the mesh clogs with creosote buildup, the cap chokes the flue instead of protecting it. This happens faster with Famco’s standard mesh than with their “high-flow” option, which most original installations didn’t include.
Replacement Cost & What’s Included
| Service | Price Range |
|---|---|
| Famco cap replacement, standard galvanized, flue sizes up to 8″ x 12″ | $280 - $360 |
| Famco cap replacement, 304 stainless, flue sizes up to 8″ x 12″ | $340 - $420 |
| Oversized or multi-flue Famco caps (custom order) | $420 - $520 |
| Crown sealant application (recommended with every cap install) | $85 - $140 |
What drives the range: flue tile condition, whether we need to grind off corroded fasteners from the old cap, and if the crown has settled enough that shimming is required for level installation. Every cap we install gets a bead of crown sealant at the base as part of our standard practice - no extra charge for the labor, just the material. Your 90-Day Done Right Promise covers the installation and sealant work in writing, no arguing. The cap itself carries the manufacturer’s warranty, which is 5 years on galvanized Famco products and lifetime on their stainless line.
DIY or Call Us?
There’s a safe middle ground here. You can check your cap’s condition from the ground with binoculars: look for lid tilt, mesh separation, or rust bleeding. You can also measure your flue tile’s outside dimensions with a tape measure from the fireplace opening if you’re comfortable on a step stool. What we don’t recommend is climbing the roof. Freeport’s coastal winds, the pitch of many older colonials, and the fact that you’re working at height over concrete patios or asphalt - it’s not worth it for a part that costs a few hundred dollars installed.
We’ve also seen DIY installs go wrong when the tension screws are overtightened and crack the flue tile, or when the cap is seated crooked and creates a dam that pools water. Our technicians carry the right torque drivers and leveling shims. Most Famco replacements in Freeport take under 90 minutes, and you’ll know the number before we start.

FAQs
Galvanized Famco caps typically last 8 to 12 years in Freeport’s salt-air climate before rust compromises the frame; stainless-steel models routinely go 20-plus years if the mesh is brushed clear of creosote annually. The coastal exposure here accelerates corrosion compared to inland Nassau County, so we lean toward stainless for any cap within a mile of the water. Call (631) 735-5125 for an exact quote - estimates are free.
Mesh reattachment and lid screw replacement are possible short-term fixes, but once the frame shows rust or the tension-screw holes are wallowed, replacement is the sound investment. We’ve tried welding patches on galvanized Famco frames, and the heat actually accelerates surrounding corrosion. Call (631) 735-5125 for an exact quote - estimates are free.
Most Famco cap replacements are completed in 60 to 90 minutes, including removal of the old unit, flue tile inspection, leveling, and sealant application. Multi-flue or oversized caps, or jobs where we need to extract broken fasteners, can run closer to two hours. Call (631) 735-5125 for an exact quote - estimates are free.
We carry the six most common Famco sizes on every truck, and our warehouse in Nassau County stocks the full line for next-day if needed. For Freeport calls, same-day installation is typical for standard flue sizes. Call (631) 735-5125 for an exact quote - estimates are free.
