Famco Chimney Cap Installation Nationwide

Famco Chimney Cap Installation: The Wilmington Owner’s Guide

Famco chimney cap installation in Wilmington typically runs $340-$680 for most single-flue and multi-flue residential caps, including removal of the failed unit, flue measurement, and proper securing to the crown or flue tile. We stock common Famco sizes on our trucks and can usually complete the swap in one visit once the flue condition is verified. Most Wilmington homeowners discover their cap has failed after a storm blows it loose, they spot rust streaks down the brick, or water starts showing up on the firebox floor.

Which Famco Models This Applies To

Famco manufactures several cap series that show up on Wilmington homes, and matching the right one matters more than most owners expect. The Single-Flue Galvanized and Stainless Steel lines are the most common, followed by the Multi-Flue and Draft King wind-resistant models we see on taller chimneys in the Brandywine and Trolley Square neighborhoods where wind exposure is higher off the river.

To identify your Famco cap, check the underside of the existing lid for a stamped model number, or measure the flue tile outer dimension - not the chimney crown. A 13″ x 13″ flue tile takes a different base attachment than a 9″ x 13″, and the Multi-Flue series requires crown-to-crown width, not flue size. We carry OEM Famco caps and quality aftermarket equivalents through our Haven buying network. The aftermarket units we source meet the same 304 stainless or galvanized spec, but the Draft King’s wind-deflector geometry is proprietary - for that series, OEM is the only fit that performs as designed. Emberly Chimney Cleaners Wilmington is an independent service provider; we are not affiliated with Famco.

Signs Your Famco Chimney Cap Is Failing

• Rust streaks running down the chimney brick. Galvanized caps in Wilmington’s coastal-humidity climate typically show surface rust at the seams within 8-12 years. Once the rust reaches the base flange, water wicks behind the cap and stains the masonry below. We document this with a roof-level photo so you can see the exact seam that’s breached.
• The cap is tilted, shifted, or missing entirely after wind. Famco caps use either screw-tension legs or a masonry-anchor base. The tension legs fatigue in freeze-thaw cycles, and the masonry anchors pull when the crown surface spalls. In Wilmington, we see this most after March storms when the crown is still saturated from winter.
• Water on the firebox floor or rust on the damper. A cap that looks intact from the ground can have a cracked mesh screen or separated lid-to-base joint. Rain enters, runs the flue, and pools where the smoke chamber meets the firebox. The camera finds this every time - the homeowner just sees the puddle.
• Birds or squirrels in the flue. Famco mesh sides are 5/8″ or 3/4″ depending on the series. If the mesh corrodes through at the weld points or a branch impact bends the frame, animals enter and nest. We pulled a starling nest from a Trolley Square flue last April; the mesh had rusted clean off on one side.
• Downdraft smoke or difficulty starting fires. The Draft King series uses a specific deflector angle to create a venturi draw. If the deflector is dented or the cap is sitting too low after a shift, the pressure balance reverses and smoke spills into the room. This is not a damper problem - it’s a cap geometry problem, and the camera confirms it in about 30 seconds.

Replacement Cost & What’s Included

What drives the range: flue height above the roofline (taller = more ladder time), crown condition (spalling requires stabilization before anchoring), and whether the old cap left corroded fasteners that need extraction. Every quote is written before work starts - Haven Standard Clause 1 - and includes the cap, all fasteners, a camera inspection of the flue top, and a photo record of the completed installation under Haven Standard Clause 4. The 365-Day Done Right Promise covers labor and materials; if the cap shifts or leaks, we make it right.

DIY or Call Us?

Here’s what you can safely check from the ground: confirm the cap is present, note any tilt, and look for rust streaks. Do not climb the roof. Chimney work above 15 feet on a pitched surface is where most homeowner injuries happen, and Wilmington’s older homes in the Westmoreland and Hilltop areas often have 8/12 or steeper pitches with brittle composite shingles.

Where DIY goes wrong: overtightening the tension legs and cracking the flue tile, using non-stainless fasteners that seize in two seasons, or installing a cap without verifying the flue liner top is intact. We’ve re-done three caps this year where the homeowner missed a spalling crown that undermined the base in six months. The camera inspection takes 10 minutes and prevents the callback. Call (610) 546-5053 - we answer live, and Corrine Halstead or a named technician will text when we’re en route.
