Famco Chimney Cap Installation Nationwide

Famco Chimney Cap Installation: The Towson Owner’s Guide

We stock and install Famco-compatible chimney caps across Towson, with most replacements running $285-$475 installed depending on flue size and whether your cap is single-flue or multi-flue. Most jobs we book are completed in a single visit, and we carry common Famco sizes on our trucks. Towson homeowners usually discover the cap has failed after finding rust flakes in the firebox, water stains on the ceiling near the chimney breast, or birds nesting in a flue they thought was protected.

Which Famco Models This Applies To

Famco produces several cap lines that show up on Towson chimneys, and knowing which you have saves a return trip. The stamped stainless-steel series, typically marked with a small Famco tag on the mesh skirt, comes in standard flue sizes from 8″×8″ up to 13″×13″ square and common round diameters from 6″ to 12″. The heavier-gauge galvanized models, more common on pre-1990 builds around the Towson area, use a bolted base ring rather than the newer tension-fit design. We match to your existing flue liner dimension, not the old cap’s outer edge, since rust can distort measurements by a half-inch or more.

OEM Famco caps are still manufactured, though lead times have stretched to three weeks on some sizes. We also source quality aftermarket equivalents from Copperfield and Gelco that meet the same 304 stainless spec and carry equivalent wind-load ratings. For Towson’s coastal-influenced climate, where salt-laden storms come off the Chesapeake, we generally recommend stainless over galvanized regardless of what was there before. Russell Haines checks the flue wall thickness and crown condition before ordering, since a cap that doesn’t seat squarely will leak within two seasons.

Signs Your Famco Chimney Cap Is Failing

• Rust staining down the chimney breast or exterior brick. Famco galvanized caps begin losing their zinc coating after 12-15 years in Maryland’s freeze-thaw cycle. Once rust appears, the metal is thinning from the inside out, and the cap is channeling water directly onto your crown rather than shedding it.
• Mesh sides pulled away from the frame or gaping at the corners. This happens when snow load or a branch strike deforms the housing. Even a quarter-inch gap admits squirrels, which can fit through holes the size of a golf ball, and Towson’s mature tree canopy makes this a regular spring call for us.
• Water in the firebox after heavy rain. A properly seated Famco cap with intact storm collar should keep all precipitation out. If you’re finding wet ash or rust streaks inside, the cap base has likely separated from the flue tile or the crown wash beneath it has eroded.
• Whistling or drafting problems when the wind picks up. The Famco design uses a specific overhang ratio to create negative pressure at the flue opening. When the lid warps or the mesh clogs with creosote buildup, that engineered draft gets disrupted and smoke can spill into the room on start-up.
• The cap is missing entirely after a storm. This usually means the original installer used generic masonry screws rather than Famco’s recommended tapcon and anchor system, or the crown itself has softened and released its grip. We see this most often on the older colonials north of downtown Towson, where original caps were retrofit in the 1980s without proper crown assessment.

Replacement Cost & What’s Included

The range depends on three things: cap size and material grade, whether your crown needs re-shaping for a weather-tight seal, and accessibility. A standard ranch roof in West Towson takes twenty minutes to reach; a three-story colonial with a steep pitch near Towson University requires additional rigging time, and we price that upfront. Our estimate includes the cap, stainless fasteners, high-temp sealant, and disposal of the old unit. Every installation carries our 90-Day Done Right Promise in writing. If water gets past our work, we come back. No paperwork, no arguing.

DIY or Call Us?

There’s no high-tension spring or electrical hazard in a chimney cap swap, which makes this one of the few chimney jobs a handy homeowner can attempt safely. What goes wrong is the finish work. A cap that looks seated from the roof edge often gaps at the back corner where the crown slopes. Without a level and a proper crown wash, you’ll have a leak you won’t discover until the ceiling stain appears.

What you can check from inside: shine a flashlight up the flue and confirm the cap is still centered and the mesh is intact. What requires a roof visit: verifying crown integrity, measuring the flue tile’s true inside dimension (not the cap’s rusted footprint), and confirming the new cap’s storm collar overlaps the crown wash by at least two inches. We carry a full Famco size run on our trucks, so if we find a surprise, we solve it that day rather than rescheduling. Call (443) 785-3816 when you’re ready for a square deal.
