Famco Chimney Cap & Crown Nationwide

Every visit starts with

Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed

Worth knowing

Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

This page is for Bethesda homeowners who already have a Famco product on their chimney, or who inherited one with a house they bought. You’ll find what fails, what it costs to fix here, and how we approach the work differently than a crew that just swaps parts and hopes for the best.

How Famco Products Fail - and How We Fix Them

Famco makes a solid cap. But around Bethesda, we see the same failure patterns repeat year after year. Here’s what we find on the roof:

  • Famco LD-series caps losing their screen bond. The galvanized mesh on older LD units separates from the hood where the spot welds sit. It starts as a small gap, then a squirrel works it loose by October. We see it most on Bethesda colonials with tall flues that take full afternoon sun on the west face. Fix: full cap replacement, usually with a stainless upgrade that holds up better than galvanized against our humidity swings.
  • Crown spalling under Famco bolt-down caps. Famco caps are designed to bolt through the crown into the flue tile. When the crown was poured thin or mixed too wet, those bolt holes become stress points and the concrete starts flaking within a few seasons. In Montgomery County, freeze-thaw cycles make it worse. Fix: we pull the cap, patch the crown properly with a crown repair mortar, and re-set the cap on a new footprint so the load spreads differently.
  • LD-series spark arrestor clogging faster than expected. Famco’s fine mesh does a good job stopping embers, but Bethesda’s tree canopy means leaf litter and maple samaras pack into the mesh faster than the manufacturer’s cleaning interval suggests. A clogged screen starves the fire of draft and pushes smoke back into the house. Fix: we clean and inspect first, and if the mesh is deformed from heat, replace the cap rather than trying to bend it back.
  • Multi-flue Famco caps with internal condensation rust. On multi-flue applications around Kenwood, we’ve pulled Famco caps that look fine from the ground but have rust blooms forming on the interior seam where the two flue channels meet. The cause is moisture contact with a seam that wasn’t fully welded before galvanizing. Fix: replacement with a fresh unit, and we inspect the crown underneath for signs that condensation is running down into the flue.
  • Famco Top series caps losing their lid rivets. The rivets on older Famco Top units work loose with expansion and contraction, which happens faster on chimneys that cycle hot-and-cold often. The lid stays on, but it rattles in wind and eventually lets water in at an angle. Fix: we replace the whole cap rather than re-riveting, because by the time rivets fail, the sheet metal around them is fatigued too.

Our Famco Chimney Cap & Crown Process

  1. 1
    You call and we talk about what you’re seeing. A live person answers, day or night. Wendell Pike himself might pick up. We ask about the cap model if you know it, when you first noticed the problem, and whether water is getting in.
  2. 2
    We schedule a visit and show up in the window we give you. Our crew arrives in uniform and brings the ladder gear needed for Bethesda roof pitches. No trip charge if you’re in the county.
  3. 3
    Diagnostics on the roof. We inspect the cap, the crown, the flue tile top, and the flashing around it. If the crown’s the problem, we’ll show you the cracking or spalling with photos. If the cap’s the problem, we’ll tell you exactly why and what it would take to patch versus replace.
  4. 4
    Parts decision. If we’re replacing a Famco cap, we talk through OEM versus quality stainless aftermarket options. Some Famco caps have been discontinued, and in those cases we match the footprint and function rather than improvising. Our trucks carry common sizes, but custom or multi-flue caps may take a few days to bring in.
  5. 5
    The repair. Cap replacements are straightforward once the old unit is off. Crown work takes longer – we grind or patch as needed, use a proper crown mortar that flexes with the weather, and check the slope so water sheds away from the flue. We never caulk over a structural crown crack and call it done.
  6. 6
    We test, photograph, and walk you through it. We light for draft, check the seal, and show you the finished work before we come down. Every Famco job is covered by our 90-Day Done Right Promise, in writing. If something’s not right, one call brings us back.

Why Bethesda Homeowners Call Top Hat Chimney for Famco Work

We’ve been at this since 1999, locally owned and owner-operated, and we’re the ones who show up at your door – not a nationwide firm that subcontracted your roof work to the lowest bidder. Wendell Pike puts his name and license number on the work, and you’ll run into him again at the hardware store on a Saturday. If you’ve got a Famco cap or crown problem, we know the product line well enough to tell you when a repair makes sense and when you’re better off replacing. And because we also work with DuraFlex, HeatShield, and Gelco products, we can match the right part to the right chimney instead of forcing one brand everywhere.
