Famco Chimney Cap Installation Nationwide

Famco Chimney Cap Installation: The Bethesda Owner’s Guide

We stock and install Famco chimney caps across Bethesda, and the typical installed price runs $340 to $680 depending on the cap size and flue configuration. If you call before 2 p.m. on a weekday, Wendell or one of his crew can usually be on your Bethesda roof within a day or two. Most folks discover their Famco cap has failed the way you probably just did: they spot rust streaks on the brick, hear a loose rattle on a windy night, or glance up after a storm and see the hood sitting crooked on the crown.

Key Takeaways

• Famco caps are good products, but the mounting hardware and aluminum screen fail long before the hood does.
• We carry Famco-compatible caps and exact-fit OEM replacements on the truck for most common Bethesda flue sizes, including 8×8, 8×13, and 13×13.
• The installed price includes the cap, rust-free stainless hardware, crown sealing, and our 90-Day Done Right Promise in writing.
• If your Famco cap is only a few years old and just loose, we’ll often re-secure it for a flat service call instead of selling you a new one.

Which Famco Models This Applies To

Famco makes chimney caps in a few lines you’ll see around Bethesda: the standard single-flue caps (SC series), the multi-flue versions that cover the whole crown (MC series), and their draft-increasing caps for flues that smoke back on windy days. The model number is stamped on the underside of the hood or on the mounting bracket, and you’ll need to know your flue tile size, not the outside dimensions of the brick. Measure the inside opening of the flue. In Bethesda’s older homes near Kenwood and Edgemoor, we see a lot of 8×8 and 8×13 clay tile flues, which take a standard square or rectangular Famco cap. The compatibility gotcha with Famco is the mounting system: their pre-2018 caps used a pressure-screw collar that corrodes at the set screws, and the newer ones use a slide-on bracket that fits differently. We’ll match the bracket style to your existing base so you’re not buying a whole new cap when the hood itself is still solid. Top Hat Chimney is an independent service provider; we’re not affiliated with Famco, but we’ve installed their caps for over two decades and stock the parts that matter.

Signs Your Famco Chimney Cap Installation Is Failing

• Rust bleeding down the brick or crown. The zinc plating on the hood or the steel screen has given out, and every rain carries iron oxide into your masonry. This is the most common failure we see on Famco caps in Bethesda’s humid summers and freeze-thaw winters.
• Loose or rocking cap when the wind picks up. The set screws or mounting legs have worked loose, or the aluminum legs snapped at the bend point. A loose cap is a roof-hazard in a storm and an easy fix before it becomes a lost cap.
• Rain or snow getting into the flue. The cap’s hood or rain fins are damaged or the cap was sized too small to overhang the flue tile. This shows up as water in the fireplace or a damp smell from the flue.
• The screen is packed with creosote or soot. A neglected cap screen restricts draft, and you’ll notice smoke hanging in the firebox instead of climbing the flue. Regular sweeps keep this from becoming a third-degree glaze problem.
• Birds, squirrels, or raccoon sounds in the chimney. The screen has torn or detached at the seam. In Bethesda’s leafy neighborhoods, squirrels exploring a torn screen are a call we get every October and November without fail.

Replacement Cost & What’s Included

A new Famco chimney cap installed in Bethesda runs $340 to $680 on average. The cap itself is $140 to $300, depending on flue size and whether you need a standard or draft-increasing model. The labor covers removing the old hardware, wire-brushing the crown surface, resetting the cap with stainless mounting legs and screws, and sealing the anchor points with a weatherproof crown sealant that handles Bethesda’s winter thaw cycles. If the crown itself is cracked or spalled, we’ll show you the camera footage and give you a separate price before any masonry work happens; nothing gets hidden in an install bill. Every Famco cap we install carries our 90-Day Done Right Promise in writing: if the cap loosens, leaks, or the screen fails inside 90 days, one call brings Wendell back at no charge. Standing offers apply: $40 off any repair over $200, and 10% off always for seniors and veterans.

DIY or Call Us?

There’s a safe version of DIY here, and a version that goes wrong. What you can safely do: check the cap from the ground with binoculars, look for visible rust, a tilted hood, or a screen that has pulled away at one corner. If you have a masonry exterior with a flat roof access, you might take a photo from a safe distance. What we don’t recommend: climbing a Bethesda slate or tile roof with a drill to swap a Famco cap yourself. Most chimney caps in this area are on rooflines with a steep pitch, and one wrong step on a damp shingle is a hospital visit. The most common DIY mistake we fix is a new cap installed with the wrong mounting bracket for the flue tile, which leaves the cap tight on day one and rattling loose by spring. If the job looks simple and you’re already on the roof, we’ll still come check it for a flat service fee. Our crew shows up with the right bracket, stainless hardware, and the crown sealant already on the truck. Call (240) 618-3233 and we’ll give you an honest price over the phone, before anyone climbs a ladder.
