This page is for Mount Vernon homeowners who already have Famco chimney components installed and need straight answers about what’s failing, what it costs, and who can fix it right. Famco products are widely used in Westchester County, particularly on homes built between 1985 and 2010, and we’ve worked on hundreds of them. Call (914) 246-5794 to speak with a live person any hour.

How Famco Products Fail - and How We Fix Them

• Famco chimney caps and shrouds (model lines 1000-3000 series) develop seam separation at the corners after 12-15 years of freeze-thaw cycling. Mount Vernon’s position between the Hutchinson River and Long Island Sound creates heavier morning condensation than inland Westchester, which accelerates galvanic corrosion at the cap’s base flange. We replace with matching-gauge Famco caps or upgrade to Gelco stainless when the flue configuration allows.
• Famco stainless steel chimney liners (SL series, especially SL200 and SL300) show creosote buildup at the upper third of the flue due to their slightly smoother interior finish, which can mask developing gaps at the collar joint. Our Level-2 camera inspection catches collar separation before it becomes a carbon monoxide pathway. We reseat with Famco-compatible expansion bands or transition to DuraFlex when the original collar is too fatigued.
• Famco masonry-style prefab chimney systems (the M-series common in Mount Vernon two-families near Fleetwood) suffer spalling at the false brick veneer when water gets behind the facing through deteriorated crown sealant. The M-series crown isn’t structural masonry; it’s a formed concrete cap that cracks predictably after 20 years. We remove the damaged veneer, treat the underlying galvanized shell with HeatShield refractory coating, and rebuild the crown with proper drip edges.
• Famco damper assemblies (rotary and poker-style, pre-2005) seize when the cast iron frame rusts to the throat. Forcing the handle twists the mounting bracket, which is no longer manufactured by Famco. We fabricate a bracket match from Copperfield hardware or install a Gelco top-sealing damper when the throat is too damaged for bracket repair.
• Famco flashing kits (standard and custom pitch models) fail at the step-flashing bend where aluminum meets the chimney saddle. The original Famco kits used .019 gauge aluminum; we replace with .027 gauge Olympia Chimney flashing or custom-fabricate from heavier stock when the roof pitch is steeper than 8:12, which is common on the older colonials around Mount Vernon’s Fleetwood neighborhood.

Our Famco Chimney Repair Process

1. 1
   Call and schedule. A live person answers, 24 hours a day. We ask about symptoms, the home’s age, and any prior chimney work. For Famco systems, we note the model line if you know it.
2. 2
   Level-2 camera inspection. Our technician arrives in uniform, runs a camera the full flue length, and photographs every defect. You see the images on a tablet while we explain what we’re looking at. No verdict without evidence.
3. 3
   Parts decision. We check Famco OEM availability against quality aftermarket alternatives from DuraFlex, HeatShield, or Gelco. Some Famco parts are back-ordered or discontinued; we tell you the lead time and price for each option, and we never install builder-grade substitutes.
4. 4
   Repair and test. Most Famco repairs finish in one visit. We pressure-test liners, verify damper operation, and run a final camera pass to confirm the fix.
5. 5
   Documentation and guarantee. You receive photos, a plain-English report, and our 90-Day Done Right Promise in writing. If it’s not right, we come back. No paperwork, no arguing.
6. 6
   Cleanup. We tarp the work area, HEPA-vacuum, and walk the perimeter with you before we leave.

FAQs

Will repairing my Famco chimney void the warranty?

Most Famco warranties on chimney components expired after 10-20 years, and the company does not require authorized service for repair work. As an independent Famco service provider, we use parts and methods that meet or exceed original specifications. Call (914) 246-5794 if you’d like us to review your warranty paperwork.

How hard is it to get Famco parts?

Famco caps, dampers, and flashing kits are increasingly allocated to distributor back-orders, and some bracket hardware for pre-2005 dampers is discontinued. We stock common Famco-compatible alternatives from Gelco and Copperfield, and we fabricate custom solutions when OEM isn’t available. You’ll know the parts situation before we start.

Should I repair my Famco chimney or replace the whole system?

Replace when the galvanized shell behind M-series veneer has rusted through, when an SL liner has multiple perforations, or when repair costs exceed 60% of a new system installed. We give you camera evidence and a straight recommendation either way. Call (914) 246-5794 for a free second opinion on any written estimate.

How often should a Famco chimney be inspected?

Annually, per NFPA 211, and sooner if you notice water stains, draft problems, or debris falling into the firebox. Famco M-series veneer spalling and SL liner collar gaps often develop without obvious symptoms until they’re serious. Our $89 Seasonal Tune-Up includes a Level-1 inspection and cleaning.

What happens if I skip Famco chimney repair?

Spalling veneer lets water reach the shell, which rusts from the inside out. A separated liner collar can leak carbon monoxide into wall cavities. Both are gradual failures that become expensive emergencies. We document what we find, prioritize by safety, and flag what can wait until next season. Call (914) 246-5794 to schedule - estimates are free.
