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 Crown Repair: The Wilmington Owner’s Guide
We stock and install Famco-compatible crown repair assemblies in Wilmington, with most jobs running $340-$680 installed depending on crown size and flue count. Same-day installation is available when we have your model spec confirmed by phone. Most owners discover the problem after a rainstorm, when water stains appear on the firebox walls or a musty smell starts rising from the hearth.
Which Famco Models This Applies To
Famco crowns break down into three product families, and getting the right match matters because the bolt patterns and flue cutouts are not interchangeable.
- Famco F-Series (F-8 through F-14): The stamped model number sits on the underside lip, visible from the firebox looking up. These use a four-bolt mounting pattern with 5.5-inch centers. We carry both OEM Famco replacements and Gelco aftermarket equivalents that fit the same pattern. The Gelco units run about $40 less and carry the same 10-year warranty.
- Famco Pro-Line (Pro-12, Pro-16, Pro-20): Heavier-gauge steel, six-bolt pattern, and a welded drip edge that the F-Series lacks. The Pro-Line stamp is on the top surface, often rusted over. If you can’t read it, measure bolt-center to bolt-center: 7.25 inches means Pro-Line. We stock the Pro-16 on the truck; the 20-inch version gets pulled from our Haven buying network by next business day.
- Famco Universal Fit (discontinued 2018): These had slotted mounting holes meant to cover multiple bolt patterns. The slots elongate over time, which is why we see so many of these leaking in Wilmington’s freeze-thaw cycles. We replace Universals with model-specific crowns, not another slotted design.
Level Two Chimney Wilmington is an independent service provider, not affiliated with Famco. We source Famco, Gelco, and Olympia Chimney crowns through Haven’s buying network to keep customer prices honest.
Signs Your Famco Crown Repair Is Failing

- Water staining on firebox walls below the damper. The crown’s primary seal has cracked or the weld at the flue collar has separated. In Wilmington, we see this most often on north-facing chimneys where ice sits longest.
- Rust flakes or orange staining on the smoke shelf. The crown’s galvanized coating has failed, usually at the drip edge where condensation collects. Once rust starts, the metal thins fast.
- Visible daylight around the flue pipe where it passes through the crown. The collar gasket has shrunk or the crown has shifted on its bolts. This gap pulls conditioned air out and dumps rain in.
- Creosote odor after rain, even when the fireplace hasn’t been used. Water mixing with creosote deposits on the smoke shelf creates a sour, sharp smell. The crown is no longer keeping the flue system dry.
- Crown sitting crooked or bolts protruding. The mounting flange has corroded through or the chimney block has shifted. This is past the point of sealant repair, the crown needs replacement.

AfterReplacement Cost & What’s Included
| Scope | Price Range |
|---|---|
| Famco F-Series crown, single flue, installed | $340-$460 |
| Famco Pro-Line crown, single flue, installed | $480-$620 |
| Dual-flue crown (any series) | Add $120-$180 |
| Flue collar re-weld or custom fabrication | Add $90-$140 |
| Smoke shelf cleaning and inspection (recommended) | Included |
The range depends on three things: crown series and size, whether the flue collar needs re-welding, and how much creosote we find on the smoke shelf that needs removal before the new crown seats clean. Every quote is written before work starts, Haven Standard Clause 1. The installed crown carries a 10-year manufacturer warranty plus our 365-Day Done Right Promise. You get a documented photo record of the old crown condition, the new installation, and the smoke shelf after cleaning, Clause 4 of the Haven Standard.
DIY or Call Us?

Here’s what you can safely check yourself: confirm the model stamp, measure bolt centers with a tape measure, and look for daylight around the flue collar from inside the firebox. Do not climb the roof to inspect the crown top. Chimney crowns sit at height on often-rotted flashing, and Wilmington’s clay tile roofs are unforgiving.
Where DIY goes wrong: the bolts are often seized with rust and require an impact driver with chimney-specific extractors. The flue collar needs resealed with high-temp silicone rated to 600°F, not hardware-store caulk. And without a camera down the flue, you can’t see if water damage has already reached the smoke chamber. We’ve found cracked flue liners hidden behind a crown that looked fine from above.
Here’s what the camera found. Here’s what it costs to fix it. You decide. Call (610) 546-5053 and we’ll confirm your model match over the phone.
FAQs
In Wilmington’s climate, a properly installed Famco crown lasts 12-18 years. The freeze-thaw cycles between December and March accelerate metal fatigue at the weld points, and the salt air from the Delaware River corridor speeds surface corrosion on north and east exposures. Call (610) 546-5053 for an exact quote on replacement, estimates are free.
Surface rust can be treated and the crown re-coated, but only if the metal is still full thickness and the flue collar weld is intact. We verify both with a camera inspection. If the crown has pinholes, cracks, or a separated collar, replacement is the only repair that passes NFPA 211. Call (610) 546-5053 for an exact quote, estimates are free.
Most Famco crown replacements take 90 minutes to two hours from ladder set to final photo. Dual-flue models or jobs requiring flue collar re-weld add 45 minutes. We bring the crown, the hardware, the sealant, and the camera on every truck. Call (610) 546-5053 to check same-day availability.
We carry F-Series and Pro-Line single-flue crowns on every Level Two Chimney Wilmington truck. Dual-flue and the discontinued Universal Fit replacements come from our next-day Haven network. We’ll confirm your model by phone so the right part is on the truck when we arrive. Call (610) 546-5053 to schedule.
