Famco Chimney Cap Installation Nationwide

Famco Chimney Cap Installation: The Falls Church Owner’s Guide

Famco chimney cap installation in Falls Church typically runs $340-$620 for most single-flue setups, including removal of the old cap, flue sizing verification, and proper storm collar sealing. We stock the common Famco galvanized and stainless-steel cap sizes on our trucks, and most replacements in Falls Church neighborhoods like West Falls Church and the Madison Lane corridor are completed in one visit. Homeowners usually discover the problem during a hard rain: water staining the firebox, a rust streak running down the brick, or the cap sitting crooked after last winter’s ice storm pulled the fasteners loose.

Which Famco Models This Applies To

Famco caps break down into three main series you’ll see on Falls Church roofs: the standard galvanized single-flue caps (SC series, typically 8″×8″ up to 13″×13″), the stainless-steel wind-directional caps (WD series), and the multi-flue custom-width models (MC series) common on the larger colonials near the West Falls Church Metro. The SC series has a stamped model number on the underside of the lid; WD series numbers are laser-etched on the directional hood. If the tag’s rusted off, measure the flue tile opening and note whether your cap has the standard 5″ skirt depth or the deeper 8″ skirt used on older masonry chimneys in this area.

We are not affiliated with Famco. We source OEM Famco caps through our distributor, and we also carry quality aftermarket equivalents from Gelco and Olympia Chimney that match Famco dimensions exactly. The aftermarket route saves roughly $40-$80 on parts without sacrificing gauge thickness. For the WD series specifically, we recommend staying with OEM; the directional vane tolerances are tighter, and we’ve seen aftermarket copies bind after two seasons of the wet freeze-thaw cycles that hit Falls Church hard in January and February.

Signs Your Famco Chimney Cap Installation Is Failing

• Water in the firebox after rain. The storm collar seal has cracked or the lid-to-skirt weld has separated. On Famco galvanized caps, this weld fails first because the galvanizing burns off at the seam from flue gas heat, leaving bare steel to rust from the inside out.
• Rust streaks down the chimney face. The cap’s finish has degraded past the point of protection. Galvanized Famco caps in Falls Church typically show this at 8-12 years; stainless-steel models last 15-20 years unless damaged.
• Cap is tilted, loose, or missing entirely. The masonry screws or expansion bolts have pulled out, often because the original installer used standard concrete anchors instead of the longer Tapcon-style fasteners needed for the soft mortar joints found in pre-1980 Falls Church brickwork.
• Smoke backup on windy days. The directional hood on WD-series caps is stuck or the internal baffles are clogged with creosote. This restricts draft and pushes smoke into the room.
• Animals or debris in the flue. The mesh screen has corroded through or the cap was installed without mesh. Squirrels in the chimney are a common late-autumn call in the tree-heavy blocks near Cherry Hill Park.

Replacement Cost & What’s Included

What drives the range: height of roof access, condition of existing flue tile, and whether we need to fabricate a custom storm collar for an oversized or offset flue. We give you the full number before we start. No surprises on the bill. The cap itself carries the manufacturer’s warranty, and our installation is covered by the 90-Day Done Right Promise - in writing, no arguing.

DIY or Call Us?

There’s a safe middle ground here. You can check: Is the cap loose by hand? Are the mesh screens intact from ground view with binoculars? Is the model number visible for ordering? Write those down.

What goes wrong with DIY: working at roof height on a chimney stack with a 12/12 pitch, which describes plenty of the two-story homes off Broad Street and Roosevelt Boulevard. The cap itself is not dangerous, but the fall is. Beyond that, improper sizing - a cap too small creates a creosote trap; too large and updraft pulls rain straight in - and failed sealing at the storm collar, which homeowners often skip because it looks fine until it isn’t. We use high-temp silicone rated to 500°F and a proper counter-flashing overlap that accounts for thermal expansion. If it is worth heating your home with, it is worth doing the chimney right.
