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.

AfterFamco Crown Repair: The Trenton Owner’s Guide
We stock and install Famco-compatible crown repair assemblies throughout Trenton, with most jobs running $340-$680 installed depending on crown size and flue count. Our trucks carry the common Famco crown profiles for same-day completion on standard residential chimneys. Most Trenton homeowners discover the problem during a routine sweep or after spotting fresh mortar crumbs in the firebox after a hard rain.
Which Famco Models This Applies To
Famco crowns break down into three series lines: the standard CC-series poured concrete crowns found on most Trenton-area homes built 1965-1995, the lighter FC-series fiber-reinforced units from the 1990s and 2000s, and the current SC-series stainless-trimmed crowns. The CC-series is the one we see most often in Hamilton Township and the older Chambersburg stock, and it’s also the most prone to spalling after freeze cycles.
To identify your model, check the stamped code on the crown’s drip edge or the metal tag under the cap if one was left by the original installer. CC-series stamps read “CC” followed by the nominal flue dimension, FC-series carry an “FC” prefix, and SC-series are marked with the full part number. If the stamp is weathered off, measure the crown’s outside width and the flue opening center-to-center, bring those numbers when you call, and we’ll cross-reference against Famco’s spec sheets.
We install OEM Famco replacement crowns where the original spec is still manufactured. When Famco discontinued the FC-813 and FC-1020 in 2019, we sourced an aftermarket equivalent from Copperfield that matches the original pour dimensions and stainless drip edge spec. We are an independent service provider, not affiliated with Famco, so we choose the part that fits correctly rather than pushing a brand.
Signs Your Famco Crown Repair Is Failing
- Horizontal cracking across the crown surface. Water seeps into these cracks, freezes overnight during Trenton’s January cold snaps, and wedges the concrete apart. By March, a hairline crack becomes a quarter-inch gap that channels water straight to the flue.
- Mortar crumbs or sand in the firebox. This is the crown’s concrete deteriorating from the top down. The material washes into the flue with rain, then settles where you can see it. If you’re sweeping out gritty debris that isn’t soot, the crown is shedding.
- Damp or stained chimney breast inside the house. A failed crown lets water bypass the flashing entirely. We see this pattern often in Trenton’s rowhouses near Broad Street Station, where the chimney runs through multiple floors and the stain shows up two rooms away from the fireplace.
- Efflorescence on the exterior brick below the crown. White mineral deposits mean water is moving through the masonry, dissolving salts, and depositing them on the surface. The crown is supposed to stop this. When it doesn’t, the brick below pays the price.
- The crown sounds hollow when tapped. A solid crown rings dull and solid. A delaminated crown, where the top layer has separated from the base, produces a hollow thud. This one takes a trained ear, but it’s a reliable tell we’ve learned to listen for.
Replacement Cost & What’s Included
| Scope | Price Range |
|---|---|
| Single-flue CC-series, standard access | $340-$480 |
| Multi-flue CC-series or FC-series replacement | $480-$620 |
| SC-series with stainless trim, or steep-roof access | $580-$680 |
| Additional flue sealing or minor brick pointing | $80-$150 per item |
The range reflects three things: crown size and series, roof pitch and access, and whether the flue needs resealing once the new crown is set. We price every job upfront after a camera inspection, and the number on the estimate is the number on the invoice. Every Famco crown repair carries our 90-Day Done Right Promise in writing, no arguing, if it’s not right we come back.
DIY or Call Us?
There’s one thing a homeowner can safely check: look at the crown from the ground with binoculars for obvious cracks or missing chunks. Don’t climb the roof. Chimney crown work happens at height, on a sloped surface, often with deteriorated mortar underfoot. The crown itself weighs 80-150 pounds, depending on series, and must be lifted, seated, and sealed in one continuous operation before the mortar skin sets.
We’ve been called to jobs in Trenton where a homeowner’s temporary patch, usually roofing cement or caulk, trapped water underneath and accelerated the damage. The repair that would have been straightforward in October became a full crown rebuild by February. If the crown’s failing, call (856) 519-0832. We’ll inspect it with the camera, show you the photos, and give you a price that doesn’t change.
FAQs
A properly installed Famco CC-series crown typically lasts 15-25 years in Mercer County’s freeze-thaw cycle, though we’ve seen FC-series units fail in 10 years when the fiber reinforcement was compromised by water intrusion. The SC-series with stainless trim is rated longer, but the real variable is whether the original installer sealed the flue interface correctly. Call (856) 519-0832 and we’ll assess yours with a camera inspection.
Hairline cracks under 1/16 inch can sometimes be sealed with a compatible crown coat if the underlying concrete is sound, but the repair is temporary, typically 2-5 years. If the crack has opened wider, or if you see spalling or hollow spots, replacement is the only fix that lasts. We don’t recommend coating over a crown that’s structurally failed, it’s paint on a rotted board. Call for a free estimate and we’ll tell you which category yours falls into.
Most Famco crown replacements we complete in Trenton take 3-4 hours from setup to cleanup, including the camera inspection and photo report. We remove the old crown, prep the brick shelf, set the new unit with proper bond break and sealant, and verify the flue joint before we leave. Our background-checked, uniformed technicians carry the common sizes on the truck, so most jobs finish in a single visit.
We stock CC-series and FC-series Famco-compatible crowns in the most common single-flue and double-flue sizes on every service truck. SC-series and uncommon multi-flue configurations we can source within 24-48 hours through our supplier. When you call (856) 519-0832 with your model stamp or measurements, we’ll confirm availability before we book the appointment, no surprises.
If the chimney’s not right, the fire’s not safe. That’s the whole job.
