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 Coventry Owner’s Guide
A Famco chimney crown repair in Coventry typically runs between $450 and $900 installed, depending on how much of the existing crown is salvageable. We stock Famco-compatible crown materials on the truck and can usually complete the job in a single visit. Most Coventry homeowners discover the crown has failed the same way: water staining on the ceiling near the flue, crumbling mortar on the chimney cap, or a drip sound in the firebox after a heavy rain.
The crown is the concrete or metal cap that sits on top of the chimney and sheds water away from the flue. When it cracks or erodes, water gets behind the brick and starts working its way down. By the time you see the stain, it’s been failing for a while. That’s why we look at the crown on every sweep, whether you asked us to or not.
Which Famco Models This Applies To
Famco makes crowns and caps for a range of chimney sizes, but most of what we see in Coventry homes falls into two groups: the standard square or rectangular crown for masonry chimneys and the round galvanized crown cap for prefab metal flues. The round caps come in common diameters from 6 to 12 inches, and there’s a Famco sizing quirk worth knowing: the listed size refers to the inner diameter of the chimney pipe, not the outer. A “6-inch” cap won’t fit a 6-inch outer pipe.
If you still have the original label or model plate, look for a series number stamped near the base. No label? Hold a ruler flat across the top of the flue pipe, outside edge to outside edge, and bring that measurement to us. For masonry crowns, we measure the full footprint and match the overhang to code so water doesn’t run down the brick face. True OEM Famco parts are fine, but for crowns we tend to use quality aftermarket stainless or cast-in-place concrete that often outlasts the original in Connecticut winters.
Signs Your Famco Crown Repair Is Failing
- Water in the firebox after rain. This is the classic tell. The crown is no longer shedding water outward, so runoff channels down the flue instead. Flue tile soaks it up like a sponge.
- Crumbling or missing mortar at the top of the chimney. You’ll see granules and small chunks of sand on the roof or in the gutter. That’s the crown’s cement washing away season by season.
- Efflorescence on the chimney bricks near the top. A white, chalky salt deposit means water is moving through the masonry and evaporating. It’s the chimney’s way of saying the crown stopped doing its job.
- Rust streaks on the chimney cap or flue. If you have a Famco metal crown cap that’s rusting through, it’s no longer waterproof. In a Connecticut freeze-thaw cycle, a pinhole becomes a split within a season or two.
- Spalling brick below the crown area. Brick faces popping off means water got inside and froze. When you see this, the crown typically needs full replacement, not patch work.
Replacement Cost & What’s Included
Here’s the honest math for Famco crown repair in Coventry:
- Crown patch and reseal (hairline cracks, small chips): $180 to $350
- Full concrete crown replacement (average 24″ x 28″ chimney): $450 to $750
- Full replacement on a large or elaborate masonry chimney: $700 to $900+
- Famco stainless crown cap replacement (6″ to 10″ diameter): $75 to $220 installed
Every one of those numbers includes labor, materials, and the crown’s written 90-Day Done Right Promise. The range depends on whether the old crown comes off cleanly or has to be ground down, how much of the top course of brick needs re-pointing, and whether the chimney is one story or three. You will have the exact number before a tool comes off the truck. No surprises at the door.
DIY or Call Us?
You can check the crown from the ground any time: look for missing chunks, visible cracks wider than a credit card, or patches that are darker than the rest. But here’s the split. Mixing and pouring a proper crown means working at height over an open flue, and the crown must be formed with a drip edge and the right expansion joint around the flue. Get those details wrong and you are back to the same leak inside two winters. If you own a bungalow with a low pitch and a gentle roof line, a confident homeowner can handle a round Famco cap replacement. If you’re on a two-story colonial out toward Nathan Hale Homestead with a steep roof, this is not your weekend project. One wrong step on a roof in fall leaves you in a cast through burning season. We install in steel-soled boots, with a spotter, and we have been doing it since 1999. Call (860) 743-7732 and one of us will explain what your crown actually needs.
FAQs
A properly poured concrete crown in Connecticut lasts 10 to 20 years before cracks start showing; a painted-on crown sealer might give you three to five. The freeze-thaw cycle in Coventry’s winters shortens every number on a crown’s clock compared to milder climates. If a previous owner used plain mortar instead of a proper crown mix, that might explain why you’re looking at this page after only a few years. We’ll tell you exactly which category yours falls into. Call us to have it checked.
Hairline cracks can be chased out, filled, and sealed, and a crown that’s mostly sound is a candidate for that fix. If the crown has broken away from the flue, has chunks missing, or lets water drip in through multiple points, patching it is a temporary job that will fail again. We won’t talk you into a full replacement if a patch is the honest fix. “If it doesn’t need doing, I’ll tell you.”
Most Famco-compatible crown replacements in Coventry take one visit of about three to five hours, including stripping the old crown, curing time, and capping the flue. If the weather is below 40 degrees or rain is moving in, we reschedule rather than pour a crown that will freeze before it sets. Concrete has a better memory than you might think, and we’d rather come back on a dry day than race the calendar.
We stock the most common Famco crown caps and sealers on the truck, and what we don’t have is sourced through our supply partners, including DuraFlex, HeatShield, and Gelco supply channels. You won’t be asked to order anything yourself or wait on a backorder you tracked down on your own. The part we install includes the same 90-Day Done Right Promise as the labor. Call us at (860) 743-7732 and we will confirm what we can bring for your Famco setup. Top Hat Chimney is an independent chimney service and not affiliated with Famco.
