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.

AfterFast, Reliable Chimney Cap & Crown Across Braintree
A chimney cap and crown in Braintree typically costs $375-$690 for a standard single-flue job, and $850-$1,400 when a multi-flue setup or crown rebuild is involved. Most Braintree appointments are completed in three to five hours, from camera inspection to final photo report. If you’re seeing rust streaks, cracked mortar, or water in the firebox, call (980) 580-8641 and we’ll put a written price in your hands before anything gets touched.
We work throughout Braintree’s mid-century neighborhoods, from the split-entries off Commercial Street to the Capes along Washington Street and the ranches near Liberty Street. This housing stock has a specific problem we know well: chimneys sized for oil-fired heat that now sit mostly idle, venting nothing but a water heater through an oversized flue. That detail changes what a cap or crown job actually needs, and it’s the first thing our Chimney Cap & Crown team looks for when the camera goes down.
Why Emberly Chimney Cleaners Is Braintree’s Preferred Chimney Cap & Crown Company
Since 2009, we’ve completed more than 38,000 chimney inspections and cleanings, every single one with a written price before work began and a documented photo record when it was done. That’s not a slogan. It’s Clause 1 and Clause 4 of the Haven Standard, and it’s stamped on every job we do in Braintree.
Braintree homeowners tend to research before they call. They want the price on the page, they want evidence, and they don’t want a flashlight inspection passed off as a real look. We agree. Every visit here includes an NFPA 211 Level 2 camera scan, which means you see what we see. Spalled tile, cracked crown, rusted cap: you’ll have photos, not a verbal summary.
Braintree dispatch is coordinated from our Boston office, and crews serving the town are background-checked and uniformed. You’ll get a named tech and a text when they’re on the way. Corrine Halstead runs the operation, and the standard she set years ago hasn’t moved: nothing gets recommended without camera evidence you can see for yourself.
Our Chimney Cap & Crown Services in Braintree
Four sub-services cover almost everything we see across Braintree’s 1950s and 1960s housing stock. Here’s what each one actually involves, and why it matters for this town’s chimneys specifically.
Cap Installation
A new stainless cap on an unlined or single-flue chimney in Braintree runs $375-$550 installed. The cap keeps rain, snow, and nor’easter-driven ice out of an open flue. For homes off Washington Street and Common Street where the original clay-tile flue is still open and unused, a cap is the cheapest way to stop water from entering the smoke chamber before it needs a liner.
Cap Replacement
Rusted-out caps are common in Braintree because wet South Shore air sits on galvanized steel for months at a time. Replacement with a Copperfield stainless cap runs $425-$690 depending on flue size. If your old cap is rusted through, we’ll show you the photo before we touch a wrench.
Crown Repair
The mortar crown on a traditional Braintree Cape or ranch takes direct hits from freeze-thaw cycles all winter. Hairline cracks widen each nor’easter, letting water into the flue and smoke chamber. Minor crown repair with grinding and fresh mortar runs $350-$550. If the crown is spalled to the point of structural failure, a full pour runs $800-$1,200.
Crown Coating
For crowns with widespread but shallow cracking, a Gelco crown coat runs $450-$700. This is the service we recommend most often in Braintree, because the freeze-thaw damage here is usually broad but shallow, and a flexible coating buys you years before a rebuild is necessary. We apply it after knocking back loose mortar so the coat bonds to a stable surface.

Common Chimney Cap & Crown Problems We See in Braintree Homes
- Freeze-thaw spalling on exposed crowns. Braintree’s wet coastal winters push moisture into mortar crowns, and every freeze cycle pops a little more material loose. By March, crowns that looked fine in October show hairline cracks that’ve widened into water highways.
- Orphaned chimneys eating caps from the inside. When a high-efficiency gas furnace vents out the side wall, the old masonry chimney often serves only a 40-gallon water heater. The oversized flue produces acidic condensate that corrodes caps and clay tiles within a few heating seasons. We see this constantly in South Braintree and East Braintree.
- Creosote slurry at the crown and damper. Braintree’s decorative fireplaces get light seasonal use, but the damp flue air means first-degree creosote builds faster than expected. If the cap is missing or damaged, rain mixes with that creosote into a corrosive paste that eats at the crown and damper assembly.
- Multi-flue confusion on Cape Cods. Braintree’s Capes often have separate flues for the fireplace and the water heater. A single-flue cap won’t do the job, and a poorly fitted multi-flue cap leaves one flue open to weather. We measure both flues and order or fabricate a cap that actually covers both.

FAQs - Chimney Cap & Crown in Braintree
Your cap is rusting because the flue below it is still venting something, usually a gas water heater, and that produces acidic condensate inside an oversized flue. The rust you see on top is the endpoint of a process that starts inside the chimney. In Braintree’s high-efficiency gas conversion homes, this pattern is common enough that we check the liner every time a rusted cap comes in. Call (980) 580-8641 and we’ll show you the camera footage before recommending anything.
Yes, in most cases. A cap covers the flue opening; it does nothing for the mortar crown that spans the top of the chimney. In Braintree’s freeze-thaw winters, unprotected crowns crack regardless of whether the flue is capped. Think of the cap as an umbrella and the crown as the roof deck; you need both to stay dry. A Gelco crown coat runs $450-$700 in Braintree and typically buys five to seven years before a rebuild is considered.
Yes, and in most cases it’s the right call. Braintree’s 1950s Capes often have two flues side by side, one for the fireplace and one for the furnace or water heater. A custom multi-flue cap covers both openings with a single unit, which is simpler than two separate caps and handles wind-driven rain better. The job typically runs $575-$900 in Braintree depending on flue spacing and crown width. We measure on site and fabricate from Copperfield stainless.
Every two years is the minimum for a Braintree home, even with no wood burning. The crown is exposed to weather regardless of use, and freeze-thaw damage accumulates whether the flue is hot or cold. On orphaned chimneys venting only a water heater, we recommend annual checks because the acidic condensate works on the crown from below while the weather works on it from above. A camera inspection takes about 45 minutes and is included in any service call.
Indirectly, yes. When the furnace is converted to high-efficiency and vents out the side wall, the old masonry chimney is left venting only the water heater. The flue is now massively oversized, and the cooler exhaust produces condensation that soaks into clay tiles and accelerates crown and cap deterioration. You won’t see it from the ground, but the camera shows it clearly. If your conversion happened years ago and the cap is now rusted, the liner likely needs attention too. Call (980) 580-8641 and we’ll show you exactly what’s going on inside.
One last thing. On a split-entry off Commercial Street in East Braintree, our tech found a rusted single-flue cap and a crown with freeze-thaw cracking from repeated nor’easter icing. We knocked back the spalled mortar, applied a Gelco crown coat, installed a Copperfield stainless cap, and confirmed the orphaned clay liner was already spalled. So we dropped a DuraFlex liner before closing the job. That’s the difference between a cap-and-crown patch and a cap-and-crown fix. If you’d rather do it once, call (980) 580-8641 and ask for the camera inspection first.
