Famco Chimney Cap Installation Nationwide

Famco Chimney Cap Installation: The Jacksonville Owner’s Guide

We stock and install Famco chimney caps and replacement components throughout Jacksonville, with most cap installations running between $285 and $520 including parts and labor. If you call before noon on a weekday, we can usually have a technician out the same day to measure, confirm the part, and get the new cap installed before rain or nesting season makes things worse. The call usually starts with a homeowner noticing rust stains streaking down the chimney chase, water dripping into the firebox after a heavy Florida downpour, or birds waking up somewhere they shouldn’t be at 6 a.m.

If you’ve got a Famco cap that’s rusted through, bent, or missing its screen, you’re probably wondering whether the whole cap needs replacing or just a component. Ruben Castellano sees this all the time in Jacksonville: salt air from the coast, months of UV exposure, and the occasional tropical storm do a number on galvanized steel. The good news is Famco caps are modular in many sizes, which means we can often replace the damaged section rather than the entire assembly. Tell me what you’re seeing and I’ll tell you what it actually means.

Which Famco Models This Applies To

Famco has been making chimney caps and venting components for decades, and their product line breaks down into a few families you’ll want to identify before calling. The most common in Jacksonville homes are the standard single-flue caps sized to fit clay tile liners ranging from roughly 6″x6″ up to 13″x17″, the multi-flue caps for homes with two or more flues side by side, and the specialty caps designed for specific applications like round metal liners, outside-mount situations, or draft-increasing needs. The model number is typically stamped on the cap’s base plate or side skirt, but after years in Florida weather, that stamp is often rusted or unreadable. In that case, we measure the flue opening itself, and the measurements are what we match against Famco’s sizing chart.

One compatibility gotcha we run into constantly: Famco sizes their caps to fit outside the flue tile dimensions, not inside them. A homeowner measures the inside of the flue at 8″x8″, orders what they think is the right cap, and it arrives too small because the outside dimension of that tile is more like 9″x9″. We measure the outside tile dimension the way Famco’s chart expects. Another gotcha: some older Famco caps use a flat base plate that sits on top of the crown, while newer models use a pressure-fit system with legs that grip the inside of the flue. If your crown is cracked or spalling, which happens a lot in Jacksonville’s heat-and-rain cycles, we may need to address that before a new Famco cap will seat properly. Alcott Chimney Jacksonville is an independent service provider, not affiliated with Famco, but we have installed their products for years and keep a working inventory of the most common sizes on our trucks.

Signs Your Famco Chimney Cap Installation Is Failing

• Rust bleeding down the brick or stucco. Galvanized steel eventually sacrifices its zinc coating, especially within a few miles of salt water. Once you see orange streaks below the cap line, the cap itself is usually too far gone to save and is now actively staining your chimney.
• Water in the firebox after rain. If your Famco cap’s hood is intact but water still gets in, the problem is frequently the seal where the cap meets the crown or a cracked crown letting water run under the cap base. In Jacksonville’s afternoon thunderstorms, this shows up fast.
• Birds, squirrels, or raccoon noise from the flue. When the screen mesh on a Famco cap tears or rusts away, the cap stops being a barrier and starts being welcome mat. We have pulled raccoon nests out of flues in Riverside and Avondale that started with a missing 4″ patch of screen.
• Wind noise or downdrafts. A bent or missing hood section changes the aerodynamics of the cap. If your fireplace starts puffing smoke on windy days when it didn’t before, that cap may have taken storm damage.
• Visible damage after a storm. Tree branches, wind-blown debris, and the occasional losing battle with a neighborhood hawk. Florida lives through this every hurricane season. If the cap is dented enough to restrict airflow, it is not cosmetic, it is a real drafting problem.

Replacement Cost & What’s Included

In Jacksonville, a standard single-flue Famco replacement cap installation runs $285 to $410 depending on flue size and whether we are doing a simple swap or addressing a damaged crown underneath. Multi-flue caps and custom sizes land between $395 and $520. The price includes removing the old cap, measuring and confirming the sizing against Famco’s chart, setting the new cap properly, and making sure it is mechanically secure, not just sitting there. We also haul the old cap away unless you want to keep it for some reason we will probably never understand.

Every Famco cap installation from Alcott Chimney Jacksonville includes our written 365-Day Done Right Promise. If anything shifts, loosens, or fails within that first year, we come back and make it right at no charge. The floor here matters more than the cap in one specific way: if the crown under your cap is cracked, no cap on Earth will keep water out. Part of our written price includes us being honest about whether the cap is actually the problem. We use professional trade materials, Famco and Copperfield among them, not box-store substitutes.

DIY or Call Us?

Here is the honest split. You can safely check a few things from the ground: look for rust streaks, check for missing screen sections with binoculars, and shine a flashlight up from the firebox after a rain to see if water is getting in. What you should not do is climb up there yourself. Chimney cap work means working at height on a sloped or flat surface that may be older than you think, often with the flue opening wider than it looks from below. Falls from even single-story roofs injure homeowners every year in Jacksonville. Let a uniformed technician with the right ladder, the right measurements, and a background check handle the actual swap.

If you are not sure whether your Famco cap is failing or you just need a straight answer about what it will cost to replace, call us at (904) 453-7823. You will get a live person, a written price before any work starts, and the name and photo of the technician who will show up at your door.
