Famco Chimney Repair in San Francisco: What to Know First
We provide independent Famco chimney repair throughout San Francisco, with most calls answered by a live person and most jobs completed in a single visit. Typical turnaround from call to repair is same-day or next-day, and we give no-hassle upfront pricing so the number on the estimate matches the number on the invoice. We’re not affiliated with Famco - we are an independent Famco service provider - which means we work for the homeowner, not the manufacturer, and we choose the fix that lasts.
This page is for San Francisco homeowners who have a Famco chimney cap, crown, damper, or venting component that is leaking, rusting, spalling, or no longer sealing. If that sounds like your situation, call (855) 408-5567. A live person will answer, and we’ll schedule a free estimate.
How Famco Products Fail - and How We Fix Them
- Famco 304 stainless chimney caps in the Richmond and Sunset districts - The 304-grade caps sold through many Famco distributors develop pinhole corrosion within 8 to 12 years in San Francisco’s salt-fog environment, especially on west-facing slopes where the marine layer lingers. We see this more often than the 316-grade caps Famco also produces. Our fix: remove the cap, inspect the flue tile for spalling caused by trapped moisture, and install a 316 stainless or copper replacement with proper overhang and mesh tension so debris and driven rain stay out.
- Famco WC wind-directional chimney caps on Edwardian flues in Noe Valley and Bernal Heights - The WC series relies on a rotating hood that seizes after years of creosote buildup and salt corrosion. Once frozen, the cap traps smoke on downdraft days, which homeowners often mistake for a drafting problem in the fireplace itself. We disassemble the hood, clean the pivot bushing, and if the housing is pitted beyond saving, we source a direct-fit replacement or fabricate a stationary directional cap that achieves the same result without the moving part.
- Famco chimney dampers in pre-1940s San Francisco masonry - The cast-aluminum throat dampers Famco supplied through the 1990s and early 2000s crack at the frame corners when subjected to thermal cycling in fireplaces that burn cordwood rather than manufactured logs. A cracked frame lets conditioned air escape year-round and admits chimney odors during high-pressure weather. We replace with a stainless steel top-sealing damper when the throat is too damaged for a drop-in replacement, which also eliminates the metal-on-metal rattle these frames develop.
- Famco Gelco-brand chimney crown coatings on flat-top San Francisco chimneys - Famco distributed Gelco crown sealant for years, and we’ve found it performs adequately on sloped crowns but pools and cracks on the flat concrete caps common in Mission District and Excelsior bungalows. The crack pattern is distinctive: radial from the flue tile, usually within 18 months of application. We grind back to sound concrete, slope the crown with mortar where needed, and apply a flexible silicone-based sealant rated for zero-pitch applications.
- Famco B-vent and direct-vent termination caps in multi-unit buildings - The snap-lock collars on Famco’s mid-2000s B-vent caps fatigue in San Francisco’s wind corridors, particularly along the western avenues where accelerated corrosion meets structural vibration. The collar separates from the vent body, creating a gap that admits water directly onto the firestop. We replace with a screw-band termination of compatible diameter, seal with high-temp silicone, and document the firestop condition with photos for the homeowner’s records.
Our Famco Chimney Repair Process
- 1
Live answer, real scheduling. When you call (855) 408-5567, a person answers. We ask what you’re seeing, check availability, and book a window that day or the next.
- 2
Level-2 camera inspection with photos. Our technician arrives in uniform, runs a camera the full length of the flue, and photographs the exterior condition. You see what we see. Warren Eckhart trained every senior technician to document like an engineer and explain like a craftsman - no jargon, no scare tactics.
- 3
Famco-specific diagnosis and parts decision. We identify the exact Famco series, assess whether OEM replacement, quality aftermarket, or fabrication is the right path, and explain the trade-off. Some discontinued Famco dampers are best served by aftermarket equivalents; some caps we fabricate from copper on-site.
- 4
No-hassle upfront pricing. You get one number. That number appears on the invoice. We do not add trip charges or “discovery fees” after the work begins.
- 5
The repair, tested and photographed. We complete most Famco repairs in a single visit. Afterward, we run a combustion draft test or water-spray test as appropriate, and we leave you with photos of the finished work.
- 6
The 90-Day Done Right Promise, in writing. If it’s not right, we make it right. No paperwork to dig up, no arguing. That’s the Keystone Standard we’ve operated under since 1984.

Why San Francisco Homeowners Call Hearthstone Chimney Co. of San Francisco for Famco Work
We’ve been on San Francisco roofs since 1984. Warren Eckhart grew up in the Outer Sunset, two blocks from where the fog rolls in off the Great Highway, and he’s spent the better part of thirty years climbing Victorian and Edwardian chimneys from the Richmond to Noe Valley. If the flue isn’t right, the fire isn’t right. Everything else follows from that.
Our technicians carry Famco-compatible inventory, plus professional-grade materials from DuraFlex, HeatShield, Gelco, and other trusted brands. When a Famco part is discontinued or a better solution exists, we say so. The 90-Day Done Right Promise covers every repair in writing. A live person answers the phone 24 hours a day, 7 days a week. Most jobs finish in one visit. And the price we quote is the price you pay.
FAQs
No. Manufacturer warranties on Famco chimney components cover defects in materials and workmanship at time of manufacture, not field repairs performed by independent technicians. As an independent Famco service provider, we use practices that preserve any remaining warranty coverage and document our work with photos. If your component is still under Famco’s original warranty, we can help you understand whether a warranty claim or a repair is the better path. Call (855) 408-5567 and we’ll sort it out.
Most common Famco caps, dampers, and termination fittings are in our San Francisco warehouse or available within 24 to 48 hours from regional distributors. For discontinued Famco lines, we fabricate equivalents from copper or source compatible aftermarket parts from Olympia Chimney or Copperfield. We do not leave a chimney open or unsafe while waiting. Call (855) 408-5567 to check availability for your specific model.
Repair is usually cheaper when the failure is localized: a seized WC cap pivot, a cracked damper frame, or crown coating cracks limited to one area. Replacement makes sense when corrosion is widespread, the component is obsolete, or previous repairs have compromised the structure. We give you both numbers upfront and tell you which we’d choose on our own home. Estimates are free - call (855) 408-5567.
Yes. Famco produced caps and components in black galvanized, stainless, and copper finishes. We stock replacement caps in matching materials and can patina copper to blend with aged installations. For painted galvanized caps, we use high-temp coatings that match the original Famco black or custom-color to your specification. Photos of your existing component help us get it right the first time.
Yes. San Francisco chimneys are often assemblies of multiple brands: a Famco cap on a DuraFlex liner with a HeatShield-treated smoke chamber and Gelco crown protection. Our technicians are trained on all the professional-grade brands we carry, and we inspect the entire system rather than isolating one component. One call handles it. Call (855) 408-5567 for a full-system inspection.
