Famco Chimney Cap Installation Nationwide

Famco Chimney Cap Installation: The Severna Park Owner’s Guide

We stock and install Famco-compatible chimney caps for most residential flue sizes found in Severna Park homes, with typical installed prices ranging from $340 to $620 depending on cap style and flue configuration. Most replacements are completed in a single visit once we confirm your model and measurements. You’ll usually discover the cap has failed when water starts dripping down the flue, you spot rust streaks on the chimney crown, or a storm has bent or blown the lid clean off.

Which Famco Models This Applies To

Famco produces several cap lines that show up on Severna Park chimneys, and matching the right one matters more than you might think. The most common we encounter are the standard galvanized single-flue caps, stainless steel multi-flue models, and the wind-directional “Vacu-Stack” series that older homes along the Magothy River favor for drafting performance in our breezy waterfront conditions.

To identify yours, check the stamped model number on the cap skirt or measure the flue tile opening, not the outside chimney dimensions. A 13×13 inch flue tile takes a different cap than a 13×13 inch chase cover, and mixing these up is how you end up with a cap that leaks or blows off in the first good nor’easter. We carry both OEM Famco caps and equivalent-grade stainless units from Gelco and Copperfield on our trucks. For most Severna Park homes, the aftermarket equivalent matches the OEM spec at a lower price point, though we keep OEM Famco wind-directional caps in stock because their counterbalanced design is proprietary and copies rarely perform the same.

Signs Your Famco Chimney Cap Is Failing

• Water dripping into the firebox after rain. The cap mesh or lid has corroded through at the weld points, or the mounting flange has pulled away from the flue tile. In Severna Park, our salt-air exposure from the Chesapeake accelerates this faster than inland Maryland towns.
• Rust stains running down the chimney face. Galvanized caps have a finite life in our climate, typically 8 to 12 years before the zinc coating gives way. Once rust starts, it travels downward and discolors brick or siding below.
• The cap is visibly tilted, loose, or missing after wind. Famco caps use either tension screws or a skirt-over-flue design. Screws back out from thermal cycling; skirt mounts rely on a tight friction fit that loosens as flue tile edges spall from freeze-thaw.
• Birds or squirrels entering the flue. The mesh sides have separated from the frame, or the lid has blown off entirely leaving the flue open. This is the failure that gets noticed fastest, usually by sound or smell.
• Draft problems or smoke spillage into the room. A Vacu-Stack cap with a seized wind vane will not pivot to align with wind direction, killing the draft boost it was installed to provide. We see this often on caps that have not been inspected in five-plus years.

Replacement Cost & What’s Included

These prices include the cap, hardware, removal of the old unit, installation with proper sealing, and a quick camera look down the flue to confirm no debris or damage below. What drives the range is flue accessibility (steep roof pitch adds time), whether the flue tile needs repair before the new cap seats properly, and cap material grade. We quote upfront before any work begins. The number on the estimate is the number on the invoice. Every cap installation carries our 90-Day Done Right Promise in writing, no arguing.

DIY or Call Us?

There is a safe middle ground here. You can check from the ground with binoculars for obvious damage, verify your model number from old paperwork, and measure your flue tile opening from inside the firebox with a tape measure. That information saves us time and gets you a firmer quote over the phone.

Actually climbing the roof to remove and replace a chimney cap is where DIY goes wrong. The work is not complicated, but the location is. Severna Park has its share of two-story colonials with 10/12 pitches and algae-slicked north slopes, especially in shaded neighborhoods like Chartwell and Olde Severna. A cap swap requires both hands free, which means working near an open flue edge while managing tools and the old cap. We have seen homeowners drop caps down the flue, bend new ones during installation, or worse. Our technicians are trained for roof work, carry the right fall protection, and handle the heavy lifting. Call (443) 464-2560 and we will get it sorted in one visit.
