Famco Chimney Cap Installation Nationwide

Famco Chimney Cap Installation: The Frisco Owner’s Guide

Famco chimney cap installation in Frisco typically runs $285-$475 for stainless steel models, including removal of the old cap, flue measurement, and proper securing to the crown or flue tile. We stock common Famco sizes on our trucks and can usually complete the job in a single visit. Most Frisco homeowners discover their cap has failed after finding rust stains on the firebox, hearing animal activity above the flue, or noticing water spots on the ceiling near the chimney breast after a hard north Texas storm.

Which Famco Models This Applies To

Famco caps break down into a few series that matter for fit. The Galvanized line (GC series) and Stainless line (SC series) use different base flange widths, and the SC-8, SC-10, and SC-13 are the sizes we see most often in Frisco’s 2005-2015 builds, where 8″×13″ and 13″×13″ flue openings are common. The Multi-Flue caps (MFC series) fit chimney crowns with two or more flues and require exact center-to-center spacing, usually 12″ or 18″ in the Starwood and Phillips Creek Ranch neighborhoods where builders spec’d larger hearths.

To identify your model, check the stamp on the existing cap’s mesh screen frame or measure the flue tile opening at the crown. The OEM Famco part number will start with the series prefix followed by dimensions, but we also source quality equivalents through our Haven buying network when the exact SKU is discontinued. Stainless is worth the upgrade in Frisco: the galvanized units we pull off after five or six years show heavy oxidation from the combination of summer humidity and winter freeze-thaw, where stainless in the same exposure typically lasts fifteen plus.

Signs Your Famco Chimney Cap Is Failing

• Rust bleeding down the chimney face. Galvanized Famco caps lose their zinc coating at the weld points first. Once water reaches bare steel, the cap sheds orange streaks that stain stucco and brick. In Frisco, we see this accelerate after hail season when the mesh gets dented and the coating cracks.
• Mesh screen pulling away from the frame. The spot-welds on older GC-series caps fatigue from thermal cycling, summer heat to winter fire. Gaps at the mesh edge let squirrels and raccoons access the flue; we’ve pulled nests from caps in Panther Creek where the screen had separated half an inch.
• Cap sitting crooked or loose after wind. Famco caps use either a base flange screwed to the crown or a tension-fit installation inside the flue tile. Screws back out as crown concrete expands and contracts; tension legs fatigue. A cap that shifts in a March thunderstorm is one ice storm away from leaving the flue fully exposed.
• Water in the firebox or rust on the damper. The cap’s primary job is to shed water before it enters the flue. When the lid cracks or the seams separate, water runs straight down the flue liner, pools on the smoke shelf, and rusts the damper mechanism. We document this with the camera every time, and the photos usually show the homeowner exactly where the cap failed.
• Smoke spillage on windy days. The Famco design uses a flat lid with overhang to create a venturi draw. When the lid dents or the side brackets corrode, the cap can actually pressurize the flue instead of drawing it. We measured this in a Frisco home near Lebanon Road where a deformed cap raised the flue draft pressure enough to push smoke into the living room.

Replacement Cost & What’s Included

What drives the range: flue tile condition, whether the existing fasteners are seized or stripped, and whether the crown needs minor resurfacing before the new cap can seat properly. We quote the full number in writing before any work starts, per Clause 1 of the Haven Standard. Every cap installation includes a camera scan of the flue to confirm no debris or damage is hidden below, and the documented photo record is archived under Clause 4. The 365-Day Done Right Promise covers the installation and the cap itself.

DIY or Call Us?

There’s one part a homeowner can check safely: whether the cap is actually loose. A gentle hand pressure test from a stable ladder, wearing gloves, will tell you if the flange screws have backed out or if the tension legs have lost their grip. Do not attempt to remove or install a cap yourself. The work happens at roof height, often on a slope, and the cap itself is awkward and wind-catch heavy. More importantly, an improperly seated cap directs water into the flue without the homeowner knowing until the liner is damaged.

We carry common Famco sizes on the truck, and the measurement takes ten minutes with the right tools. If you’re seeing any of the symptoms above, call (940) 290-7230 and we’ll get a technician out with the cap in hand.
