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 Leominster Owner’s Guide
Famco crown repair in Leominster typically runs $340-$680 installed, depending on whether we’re sealing a cracked concrete crown or replacing a deteriorated metal cap entirely. We stock Famco-compatible crown repair materials on our Leominster trucks, and most jobs are completed in a single visit once the inspection is done. You’ll get a written price before work starts and a photo record of the finished repair under Clause 4 of the Haven Standard.
Most Leominster homeowners discover crown trouble during a routine sweep, or after water stains appear on the ceiling below the chimney during our wet New England springs. The crown sits at the very top of your chimney, and its job is simple: shed water away from the flue opening. When it fails, water goes exactly where you don’t want it.
Which Famco Models This Applies To
Famco manufactures several crown and cap configurations, and matching the right repair approach matters. The stamped metal chimney caps (series 300 and 500) use a different mounting geometry than the concrete pour-style crowns found on older Leominster Colonials near Monument Square. If your cap has a Famco label, check the underside for a stamped model number, usually near the mesh screen attachment point. No label? Measure the flue tile outer dimension and the chimney top footprint, corner to corner.
We source Famco materials through Haven’s buying network alongside DuraFlex, HeatShield, and Gelco products. For most Famco metal caps, we can install an OEM-equivalent crown assembly that matches the original spec. On concrete crowns, we often use HeatShield CrownCoat or a poured replacement, depending on how far the cracking has progressed. The key compatibility gotcha: Famco’s 300-series caps require a minimum 13-inch by 13-inch chimney top surface. Anything smaller, and the flange won’t seat properly, which we’ve seen more than once on the narrower 1960s-era chimneys in Leominster’s North End.
Signs Your Famco Crown Repair Is Failing

- Water stains on the ceiling near the chimney breast. This means water is getting past the crown and running down the flue liner or the chimney’s exterior surface. In Leominster, we see this most often after freeze-thaw cycles in late winter, when a hairline crack in the crown opens wide enough to let water through.
- Spalling or flaking on the brick faces below the crown. When the crown doesn’t overhang the chimney properly, or when its slope has flattened, water runs down the masonry instead of away from it. The brick faces absorb that moisture, and in Massachusetts weather, the freeze-thaw cycle pops the surface right off.
- Rust stains on the chimney exterior or the firebox. Famco metal caps can develop seam separation or screen detachment that lets water reach the flue liner. If you see orange staining, water has already found a path, and the steel damper or firebox components may be corroding.
- Visible cracks or missing chunks in the crown surface. Concrete crowns should have a clean, domed profile with a drip edge. Cracks wider than 1/8 inch are past the point of sealant repair in most cases, especially if they’re running toward the flue opening.
- Draft problems or smoky fireplace operation. A deteriorated crown can allow debris, nesting material, or water to obstruct the flue. We’ve pulled saturated chimney swift nests out of Leominster flues where the crown mesh had corroded through, and the resulting blockage was choking the draft.

AfterReplacement Cost & What’s Included
| Service | Typical Range in Leominster | What’s Included |
|---|---|---|
| Famco metal cap replacement (OEM-equivalent) | $340-$520 | Cap, mesh screen, mounting hardware, sealant, photo record |
| Concrete crown seal with HeatShield CrownCoat | $280-$420 | Surface prep, application, 15-year material warranty |
| Full concrete crown replacement | $520-$680 | Form and pour, reinforced concrete, proper slope and overhang, photo record |
| NFPA 211 Level 2 inspection (required first) | $180-$240 | Camera scan, written findings, written price before any repair |
The price range depends on three things: how we access the roof (walkable vs. steep pitch), whether the flue tile needs repair before the new crown goes on, and whether we’re matching a Famco OEM part or adapting a quality equivalent. Every job gets a written scope and written warranty before we start, per Clause 1 of the Haven Standard. The 365-Day Done Right Promise covers all crown work, and we document the finished repair with photos under Clause 4.
DIY or Call Us?

Here’s what you can safely check yourself: look at the crown from the ground with binoculars for obvious cracks, rust, or missing pieces. Check the attic for water stains after heavy rain. That’s about where safe homeowner inspection ends.
Crown work happens at roof height, and the consequences of getting it wrong are expensive. A poorly sealed crown dumps water into your chimney system for months before symptoms show inside. Worse, a metal cap that’s not properly secured becomes a projectile in a Leominster winter windstorm. We don’t recommend DIY crown replacement, and we won’t sell you parts alone for this job. The camera goes up first. Everything else follows the footage. Corrine Halstead and our crew have replaced Famco crowns on roofs across Leominster where the pitch alone made the work genuinely hazardous.
Call (978) 481-2900 and we’ll book the inspection. Written price before work starts, every time.
FAQs
A properly installed Famco metal cap typically lasts 15-20 years in central Massachusetts, though the mesh screen may need attention sooner if you’re burning regularly. Concrete crowns, if formed and poured correctly with proper slope and overhang, should last 20-30 years, but we’ve seen premature failure in Leominster when the original pour was flat or lacked reinforcement. Harsh freeze-thaw winters and the occasional summer deluge are hard on any crown material. Call (978) 481-2900 for an exact quote on inspection, estimates are free.
Hairline cracks in a concrete crown can sometimes be sealed with HeatShield CrownCoat if the crown still has proper slope and overhang, and if the crack hasn’t reached the flue tile. Metal Famco caps with seam separation or screen corrosion are generally replace-only, sealant won’t hold. We make that call after the camera inspection, not before, and we’ll show you the photos so you can see what we see. Call (978) 481-2900 for an exact quote, estimates are free.
Once we’re on site with the right Famco-compatible part, most crown replacements take 2-3 hours from setup to cleanup. Concrete crown pours require a return visit after the cure period to remove forms and seal. We schedule the inspection first, deliver a written price, and if you approve, book the repair for the next available slot. Call (978) 481-2900 for an exact quote, estimates are free.
We stock common Famco-compatible crown assemblies, sealants, and mesh screen replacements on our Leominster trucks, though we confirm the exact model during the NFPA 211 Level 2 inspection before dispatching with parts. For less common Famco configurations or custom sizes, we order through Haven’s buying network and typically have the part within 48 hours. Either way, you get a written price before anything is ordered or installed. Call (978) 481-2900 for an exact quote, estimates are free.
