Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Famco Chimney Cap & Crown in Mount Vernon: What to Know First
We provide independent Famco chimney cap and crown service in Mount Vernon, with most repairs completed in a single visit and upfront pricing agreed before we start. A standard Famco cap replacement runs $280-$520, while crown repair or coating typically falls between $450-$890 depending on accessibility and flue count. We’re an independent Famco service provider - not affiliated with or authorized by the manufacturer - which means we source the right parts for your unit without the markup or delay of factory channels.
This page is for Mount Vernon homeowners who already have a Famco cap or crown showing rust, separation, or water staining, or who need a replacement that actually fits their flue configuration. If you’re seeing drips in the firebox, rust streaks on the brick, or a cap that’s shifted after a windstorm, we can sort it out. Call (914) 246-5794 - a live person answers, 24 hours a day.
How Famco Products Fail - and How We Fix Them
- Famco 304 Stainless Single-Flue Caps - weld-seam corrosion near the salt air. Mount Vernon’s proximity to Long Island Sound means chloride exposure accelerates seam failure on the 304-grade line, particularly on homes south of the Cross County Parkway. We see this show up as pinhole leaks at the corner welds before the cap itself looks worn. Our fix: replace with 316 marine-grade or a properly fitted Famco 316 upgrade, reseating with high-temp silicone and stainless hardware that won’t gall.
- Famco Multi-Flue Caps - mesh screen sag on the GL series. The expanded metal mesh on older GL multi-flue units can belly downward from thermal cycling, especially when the fireplace sees daily winter use. That sag traps creosote and restricts draft. We measure the existing frame in situ and either rescreen with heavier 18-gauge mesh or source a direct-fit replacement cap if the frame has warped.
- Famco Draft King Caps - damper-mechanism freeze-up. The integrated top-sealing damper on Draft King units uses a stainless cable that can corrode inside the flue if the chimney crown has already cracked and moisture is entering the system. We don’t just replace the cable; we trace the leak path, repair the crown or flashing as needed, then install a new Famco cable assembly or convert to a separate damper if the housing is pitted.
- Famco Copperfield-labeled Caps - galvanic reaction at aluminum base rings. Some Famco caps sold through Copperfield channels in the 2000s used aluminum base rings against stainless bodies. In Mount Vernon’s freeze-thaw climate, that dissimilar-metal junction corrodes aggressively. We replace with all-stainless base hardware and seal the joint with a flexible crown coat that moves with temperature swings.
- Famco Crown Seal Coatings - delamination on poured concrete crowns. When Famco’s elastomeric crown coating is applied over a crown that’s already spalled or structurally cracked, it traps moisture and peels within two seasons. We grind back to sound concrete, patch with hydraulic cement, then apply the coating to a surface that can actually accept it. In Fleetwood and near the Hutchinson River, we’ve found crowns on 1920s two-families are often too far gone for coating alone - we tell you straight when that’s the case.
Our Famco Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, day or night. We ask for your Famco model if you know it, the age of the installation, and what you’re seeing - rust, water, draft problems, or animal entry.
- 2
Level-2 camera inspection on arrival. Our technician documents the cap or crown condition with photos you can see, plus the flue interior below. No guesswork. No “trust me.”
- 3
Parts decision: OEM Famco or quality equivalent. If your cap is a current Famco SKU, we can source it. If it’s discontinued - the older GL-800 series, for instance - we fabricate or source from Gelco or Olympia Chimney with matching gauge and fit. We explain the trade-off and let you choose.
- 4
Repair or replacement with no-hassle upfront pricing. The number on the estimate is the number on the invoice. We complete most Famco cap and crown jobs in one visit.
- 5
Post-repair draft test and photo documentation. We verify proper draw, check for leaks with a water test when practical, and leave you with photos of the finished work.
- 6
90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork to dig up, no argument.

FAQs
No - Famco’s limited lifetime warranty on stainless caps covers manufacturing defects, not installation or weather damage. As an independent Famco service provider, we document the failure mode with photos so you have evidence if a defect claim is warranted. For warranty submission, you’ll need your original receipt; we can help identify the model and manufacturing marks. Call (914) 246-5794 if you’re unsure what you have.
Many Famco caps from the 1990s and 2000s are discontinued, but we cross-reference dimensions and source quality equivalents from Gelco or Olympia Chimney that match or exceed the original gauge. For the GL-800 multi-flue series and early Draft King housings, we often fabricate from 304 or 316 stainless to fit your existing flue layout. We never leave you waiting on a backorder that may not come.
If the frame is intact and only the mesh is sagging or a minor seam is weeping, repair is usually practical. If the base ring is rotted through, the lid has warped from a chimney fire, or multiple weld points have failed, replacement is the sounder spend. We show you the photos and give a straight recommendation. If it needs doing, we’ll tell you. If it doesn’t, we’ll tell you that too.
A properly applied elastomeric crown coating on sound concrete lasts 8-12 years in our climate. The key words are “sound concrete.” In Mount Vernon, where freeze-thaw cycles are sharp and crowns on pre-war construction are often poured too thin, we see coatings fail in two seasons when applied over hidden cracks. We grind and patch first, then coat - or recommend rebuild if the substrate won’t hold. Call (914) 246-5794 and we’ll assess what you’ve got.
Water enters the chimney system, freezes, and expands - widening cracks, corroding the flue liner, and eventually damaging interior finishes. Carbon monoxide risk rises if the liner deteriorates, and creosote buildup accelerates in a restricted flue. That said, not every crack is an emergency. We grade the severity during inspection and tell you plainly what can wait a season and what should be addressed before the next hard freeze. Call (914) 246-5794 for a free estimate.
