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 Denton Owner’s Guide
Famco chimney cap installation in Denton typically runs $340-$620 for most single-flue and multi-flue residential caps, including removal of the failed unit, flue measurement verification, and proper securing to the crown or flue tile. We stock common Famco sizes on our trucks and can usually complete the swap in one visit. Most Denton homeowners discover the problem after a storm blows the cap off, or when water starts dripping down the flue during the hard rains that hit north Texas in April and May.
Which Famco Models This Applies To
Famco caps break down into three main series you’ll see around Denton: the standard galvanized single-flue caps (SC series), stainless multi-flue models (MSC series), and the wind-resistant line with internal baffles popular in the wind corridors near Ray Roberts Lake. The SC series uses a simple screw-tension mount to the flue tile; MSC units bolt to a mounting bracket on the crown. Check the underside of your existing cap for a stamped model number, usually on the skirt or cross-brace. If the stamp’s rusted away, measure the flue opening width and depth, plus the total crown dimension if you’re looking at a multi-flue cap.
We source Famco caps direct through Haven’s buying network, but we also carry quality aftermarket equivalents from Gelco and Olympia Chimney when the OEM lead time stretches past what the weather will allow. The aftermarket units match Famco’s 304 stainless spec and carry the same 10-year warranty. One compatibility gotcha: Famco’s wind-resistant baffle caps require a minimum 9-inch flue height above the crown to seat properly. We’ve measured caps on Denton homes where previous installers ignored this and wedged the unit on a 6-inch flue, which voids the warranty and lets blow-back drive rain straight down the pipe.
Signs Your Famco Chimney Cap Installation Is Failing

- Visible rust streaks down the chimney face. Even “stainless” Famco caps can show surface corrosion if installed with galvanized hardware instead of stainless fasteners. The rust runs down the brick and stains mortar joints, which is usually how owners spot the problem from the driveway.
- Water dripping into the firebox during rain. This means the cap’s mesh screen has separated from the skirt, or the lid has warped from heat cycling and no longer overhangs the base correctly. In Denton’s clay-heavy soils, that water accelerates spalling on the firebox rear wall.
- The cap rattles or shifts in wind. The mounting screws have backed out, or the flue tile itself has cracked at the top from thermal stress. Either way, the next strong north Texas thunderstorm is likely to deposit the cap in your yard.
- Birds or squirrels entering the flue. Famco’s mesh sides are 5/8-inch weave, which blocks most animals unless a section has corroded through or been bent by a falling branch. We find this most often on caps near mature post oaks in the neighborhoods west of the Square.
- Smoke spillage into the room on startup. The cap’s internal baffle has collapsed or the mesh is packed with creosote, choking draft. This is more than a nuisance; it’s a carbon monoxide risk if the spillage happens with a gas insert running.

AfterReplacement Cost & What’s Included
Here’s how Famco chimney cap installation prices break down in the Denton market:
| Cap Type | Parts + Labor Range | Typical Scenario |
|---|---|---|
| Single-flue galvanized (SC series) | $340-$420 | Standard ranch flue, good crown condition |
| Single-flue stainless (SC-SS series) | $420-$520 | Most common replacement we do |
| Multi-flue stainless (MSC series) | $480-$620 | Two or more flues on one crown |
| Wind-resistant baffle cap | $520-$680 | High-wind exposure, 9″+ flue height required |
| Crown repair + cap replacement | $780-$1,400 | Spalling or cracked crown beneath the cap |
What drives the range: crown condition (we won’t bolt a new cap to crumbles), flue height and diameter, whether we need to extract broken fasteners from a previous install, and stainless versus galvanized. Every quote is written before we start, with the scope, the price, and the warranty on one page. Haven Standard Clause 1 requires it. The cap itself carries the manufacturer’s warranty; our labor is covered by the 365-Day Done Right Promise.
DIY or Call Us?

What you can safely check: look at the cap from the ground with binoculars. Note rust location, whether the lid sits level, and if mesh panels are intact. Check the firebox for water stains or debris. That’s the limit of what we’d advise.
What goes wrong with DIY: most Denton homes have 8/12 or steeper roof pitches, and chimney stacks sit at the ridge or on an exterior wall end. Working at height with tools near a flue edge is where falls happen. Beyond that, improper fastening cracks flue tile, wrong cap sizing chokes draft or lets rain in, and we’ve found homeowner installs where the cap was secured with deck screws into mortar that pulled out in six months. Corrine Halstead’s rule: “The camera doesn’t guess - and neither do I.” We verify flue condition with a camera scan before quoting, because a cap on a cracked flue is money thrown away.
If you’re seeing any of the symptoms above, call (940) 373-6912. We’ll answer live, schedule a camera inspection, and leave you with a written price before any work starts.
FAQs
A properly installed stainless Famco cap lasts 15-20 years in north Texas conditions, though the intense UV and hail exposure we get west of I-35 can shorten that to 10-12 years on south-facing exposures. Galvanized caps show rust in 5-7 years. Call (940) 373-6912 for a free inspection if you’re unsure of your cap’s age or material.
Mesh rescreening and fastener replacement are possible if the lid and skirt are structurally sound, but we find most Denton caps coming to us have reached the point where the metal itself is thinning at stress points. We don’t quote repairs that won’t last two full burning seasons. Bring us a competitor’s written repair quote for a free second opinion.
Most Famco chimney cap replacements take 45-90 minutes on site, assuming the crown and flue tile are in good condition. If we find hidden damage during the camera inspection, we’ll show you the footage and revise the written scope before proceeding. Haven Standard Clause 4 requires that photo record, and you’ll get a copy.
We carry the four most common stainless single-flue and multi-flue sizes that fit Denton-area flues, plus mounting hardware in stainless and masonry anchors. Specialty sizes or wind-resistant baffle caps typically require a next-day pull from our supplier network through Haven’s buying group. We’ll tell you exactly what’s on the truck when you call (940) 373-6912.
