Famco Chimney Cap Installation: The San Antonio Owner’s Guide

Famco chimney cap installation in San Antonio typically runs $285 – $520 installed, depending on the cap size, flue tile condition, and whether we’re also repairing the crown it mounts to. We stock Famco-compatible caps in the most common San Antonio flue sizes on our trucks, so most installs get done in a single visit. Most owners discover they need one after a hard rain leaks down the flue, or they hear birds scratching inside the chimney in early spring.

Danny Cortes has replaced enough Famco caps across San Antonio to know exactly what fails first here: the stainless mesh screen, then the mounting hardware. The Texas sun bakes the galvanized bases on older models, and the freeze-thaw cycles in January and February are rough on anything attached with cheap sheet-metal screws. If your cap looks rusted through or leans like a tired cowboy hat, it’s time.

Which Famco Models This Applies To

This guide covers the Famco SC, FC, and CC series caps most commonly found on San Antonio homes built between 1985 and 2010. The SC series is the stainless steel multi-flue cap; the FC is the single-flue round cap; the CC is the rectangular cast-aluminum cap with the hinged top. Each series has its own mounting footprint, and here’s the compatibility gotcha most homeowners run into: the flue tile measurement on the chimney crown is not always the model number printed on the old cap. We regularly see a cracked FC-10 mounted over a tile that actually measures 10.5 inches outside diameter because the original installer chipped the corners to make it fit.

On the OEM versus aftermarket question for Famco specifically: Famco caps are well built, but their older galvanized models corrode faster in San Antonio’s humidity than the marine-grade aftermarket caps from brands like Olympia Chimney and Gelco. If you’re replacing a galvanized Famco unit, we’ll usually recommend an aftermarket stainless or copper equivalent that outlasts it. If you have a stainless Famco SC cap with good metal and a torn mesh, we can often replace just the mesh panel rather than the whole assembly. That’s the kind of repair that saves a family $200, and it’s the sort of thing we look for before quoting a full replacement. Kindling Chimney San Antonio is an independent service provider; we are not affiliated with Famco, but we do stock Famco-compatible parts and install them regularly.

Signs Your Famco Chimney Cap Installation Is Failing

• Water streaks or efflorescence on the interior brick above the firebox. The cap’s soldered seams have opened, or the mounting caulk has dried and cracked. Water is getting in around the cap base, not through the top.
• Bird or squirrel sounds in the chimney. The mesh screen has a hole or has pulled away from the frame at the corner. In San Antonio, chimney swifts try to get in starting in March, and once a nest starts, it’s a bigger removal job.
• Rust staining down the exterior brick or stucco. The cap’s galvanized steel skirt is corroding and bleeding down the chimney. It’s cosmetic now, but the same rust is eating the mounting hardware.
• The cap sits tilted or rattles in strong wind. The screws that clamp the cap to the flue tile have stripped out or the crown mortar underneath has crumbled. San Antonio afternoon thunderstorms will finish the job.
• Debris, leaves, and twigs inside the firebox. The cap’s spark arrestor mesh has failed and the chimney is open to falling material. This also means embers can exit the flue during a burn.

Replacement Cost & What’s Included

For a standard single-flue Famco cap replacement in San Antonio, expect to pay $285 – $360 installed. Multi-flue caps run $380 – $520 installed because they require drilling into the crown and anchoring to the brick. If the flue tile itself is spalled or the crown has cracks, we’ll address that before mounting the new cap, and that adds to the job but we’ll tell you exactly how much before any work starts. You get a written price before we begin, on every visit, and that’s not an upsell, it’s how we work. The 365-Day Done Right Promise covers the install: if the cap isn’t right, we make it right.

What’s included: the new cap or replacement mesh, stainless steel mounting hardware, a high-temperature masonry sealant, removal and haul-away of the old cap, a photo of the installed cap before we leave, and a written note of the flue tile condition underneath. No on-the-spot add-ons, no “while we’re here” surprises.

DIY or Call Us?

There’s an honest split here, and the honest answer for most homeowners in San Antonio is: call us. A chimney cap lives at the highest point of your roofline, and getting to it means ladder work on uneven ground, at height, usually over a sloped roof. The risk of a bad fall is real, and the tools needed to properly seat and seal a cap on a flue tile are specific. Danny grew up in Los Angeles and learned his trade fundamentals at Los Angeles Trade-Technical College before working chimneys across the Southwest for nearly two decades, and he’s seen too many DIY cap installs that leaked because the old mounting point wasn’t prepped. That said, you can safely do the diagnosis from the ground: look for the tilt, the rust, the missing mesh, and the water streaks. Knowing what’s wrong helps you get an accurate phone quote. Call (361) 491-3153 and we’ll talk through what you’re seeing, give you a real number, and get it handled.
