Famco Chimney Cap Installation Nationwide

Famco Chimney Cap Installation: The Pottstown Owner’s Guide

We stock and install Famco-compatible chimney caps across Pottstown, with most jobs running $340-$680 installed depending on flue size and whether your crown needs repair before the cap goes on. If you call us by early afternoon, we can usually get a technician out the same day - our trucks carry the common Famco sizes for single-flue and multi-flue setups. Most Pottstown homeowners realize their cap has failed when they spot rust streaks down the brick after a hard rain, or when a neighbor mentions birds nesting in their chimney come spring.

Which Famco Models This Applies To

Famco builds chimney caps in three main series that we see around Montgomery County: the standard galvanized line, the stainless-steel series, and the copper architectural caps common on the older stone homes up near Hill School. The label you’re looking for is stamped on the underside of the cap flange or embossed on the mesh screen frame - it’ll read “Famco” followed by a model prefix like SC (single flue), MC (multi-flue), or CC (custom copper).

Here’s where owners get tripped up: Famco changed their flange width in 2017. Pre-2017 caps need a 2¾-inch minimum ledge; post-2017 dropped to 2¼ inches. Measure wrong, and your cap sits proud of the crown, catching wind like a sail. We carry both flange profiles on the truck, plus the adapter brackets for retrofit jobs. Hearthstone Chimney Co. is an independent service provider - not affiliated with Famco - so we’ll tell you straight when an aftermarket equivalent from Gelco or Olympia Chimney matches the spec at a lower price point. For the stainless series, we typically recommend staying OEM; the mesh gauge and welds are specific, and we’ve seen cheap substitutes rust through in three Pottstown winters.

Signs Your Famco Chimney Cap Is Failing

• Rust bleeding down the chimney face. Famco’s galvanized caps carry a 20-year warranty, but that assumes proper slope and drainage. In Pottstown, where freeze-thaw cycles run from late October through April, standing water in a deformed cap accelerates rust at the seams. The streaks you see are iron oxide washing out - and once it starts, the cap is rotting from the inside.
• Mesh screen pulling away from the frame. This happens when the spot-welds fatigue, usually after a decade of thermal cycling. The gap looks small, but it’s enough for squirrels to force through. We’ve pulled nests out of flues in West Pottsgrove where the homeowner never noticed the separation until the smell arrived.
• Cap tilted or shifted after wind. Famco caps mount with masonry screws into the crown. If the crown itself has hairline cracks - common on Pottstown homes built before 1980 - the screws loosen and the cap walks. A tilted cap directs water into the flue instead of away from it.
• Visible gaps between cap and flue tile. The collar on a single-flue Famco should seat tight, with a ¼-inch tolerance. Gaps mean either the flue tile has spalled at the top, or the cap was never the right size. Either way, rain’s getting in every storm.
• No cap at all - just the flue sticking up. Sometimes the cap blows off completely. After the March windstorms we get along the Schuylkill, we field three or four calls a week from owners who walked outside and found their cap in the neighbor’s azaleas. If you’re missing hardware, we need to inspect the crown anchors before replacing.

Replacement Cost & What’s Included

The price moves based on three things: cap material (galvanized, stainless, or copper), whether we need to drill new anchor holes or reuse existing ones, and the condition of the crown beneath. We don’t quote over a photo - a technician climbs, inspects with a camera, and shows you the crown close-up before you decide. Our estimate is the invoice number. No surprises. The cap itself carries Famco’s warranty, and our installation is covered by the 90-Day Done Right Promise - in writing, no arguing.

DIY or Call Us?

There’s one thing you can safely check from the ground: whether the cap is still there, and whether it’s sitting level. Use binoculars. Don’t climb.

Everything else belongs on a ladder or roof, and chimney work at height carries real risk - the crown surface is often crumbly, the slope is steeper than it looks, and a Famco cap in a 24-inch size catches wind like a dinner plate. We’ve seen homeowners strip anchor holes, crack the crown with the wrong drill bit, or install a cap that overhangs the flue and traps condensation. Worse, a cap installed without a camera inspection can hide a cracked flue liner or deteriorated mortar joints that the new cap will only accelerate.

We carry Famco caps, Gelco equivalents, and the full anchor hardware assortment on every truck. Most swaps take 45 minutes to an hour once we’re on the roof. Call (610) 819-4281 and we’ll get you scheduled.
