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.

What makes New Britain different is the housing stock itself. A century of factory-built two-families and triple-deckers means your chimney probably isn’t a simple single-flue pipe. It’s a shared brick stack carrying two, three, sometimes four separate flues, each running to a different unit, each with its own fuel history and its own set of problems. If you’re looking for Chimney Cap & Crown work on that kind of structure, you need someone who understands what happens when one flue fails and how that affects the units below it.
Why Emberly Chimney Cleaners Is New Britain’s Preferred Chimney Cap & Crown Company
We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a meaningful share of those have been in New Britain’s pre-WWII brick stacks. What that volume teaches you is that every triple-decker has a story in its flues. Coal to oil. Oil to gas. Liners patched, replaced, or never touched. We walk onto a roof off Broad Street or Arch Street knowing what to look for before the ladder is fully extended.
Our crews are background-checked and uniformed, and you’ll know who’s coming before they arrive. We answer our phones 24/7 with a live person, not a voicemail tree. And every job, without exception, gets a written price before anyone touches your chimney. That’s Haven Standard Clause 1: have it in writing. Corrine Halstead, who leads our team, built that standard to make sure no homeowner in New Britain ever has to guess what a cap or crown repair will cost.
We carry materials from Famco, Copperfield, and Gelco, so when your East Side triple-decker needs a custom multi-flue cap, we’re not ordering it from a catalog and hoping it fits in three weeks. We measure, fabricate, and install with parts built for the job. That’s the difference between working with a company that knows New Britain’s buildings and one that treats them like any other chimney.
Our Chimney Cap & Crown Services in New Britain
Cap Installation
A properly sized cap keeps rain, birds, and debris out of your flue while preserving draft. On New Britain’s converted gas flues, undersized caps are a real problem. A flue sized for a coal furnace was never meant to vent a modern gas appliance, and slapping a cap on without checking the termination can choke off combustion air. We install caps sized to the appliance, not to the brick opening. That matters when three units share one stack and each flue needs a different termination.
Cap Replacement
Rust-through is the most common reason caps fail. In New Britain, add the freeze-thaw cycle: a galvanized cap that’s been through 40 Connecticut winters is often perforated at the seams, letting water pour directly into the flue. We replace failed caps with stainless or copper options, and when the old cap was never sized right in the first place, we correct the termination, which often fixes draft complaints that have gone unsolved for years.
Crown Repair
This is where New Britain’s triple-deckers get expensive if ignored. The crown is the concrete or mortar slab at the top of the chimney that seals the top of the brick. On 1890-1940 soft-mortar chimneys, freeze-thaw expansion cracks crowns in predictable patterns. Water gets in, masonry spalls, and eventually the liner masonry starts to degrade. We rebuild cracked crowns, repoint the top courses where necessary, and apply a crown coat to stop the cycle.
Crown Coating
Gelco crown coating is a flexible sealant that moves with the chimney through freeze-thaw cycles. It’s not a patch, it’s a rebuild of the waterproofing layer. On New Britain’s older chimneys, where the original crown was often little more than sloped mortar, a proper coat buys years before a full rebuild is needed. We use it on every crown repair as standard, not as an add-on.
Multi-Flue Cap
Multi-flue caps are different from buying three separate caps and hoping. On a triple-decker off Broad Street in the East Side, our crew found a shared exterior stack with three active flues and a severely spalled crown that was shedding soft lime mortar into all three flue openings. We installed a custom multi-flue copper cap and rebuilt the crown with a Gelco crown coat, sealing each flue termination separately to stop rain and animal entry without closing off draft for any unit. That’s the job. Done right, all three units are protected. Done wrong, one tenant gets draft problems and the landlord gets three calls in one week.
Custom Cap
When the stack is irregular, or when one flue is active gas, one is a dormant coal flue, and one vents a wood stove, off-the-shelf caps don’t work. We fabricate custom caps that seal what needs sealing and vent what needs venting. On New Britain’s older stacks, this is more common than not.

We install and service caps and crowns from Famco, Copperfield, and Gelco. We stock the common sizes and fabricate the rest, which means your New Britain chimney isn’t waiting on a backorder from a distributor on the other side of the country. For multi-flue stacks on older New Britain buildings, Copperfield’s custom copper work is often the best answer: it lasts longer than galvanized, handles the city’s freeze-thaw abuse, and looks appropriate on a century-old brick stack. Gelco crown coats are our standard for crown repair. When you need a specific brand’s product installed or maintained, call (980) 580-8641 and ask.
Common Chimney Cap & Crown Problems We See in New Britain Homes
- Freeze-thaw crown cracking in pre-WWII brick. Soft lime mortar from the 1890s through the 1940s can’t absorb decades of Hartford County freeze-thaw cycles without spalling. When the crown cracks, water migrates down into the stack and attacks every flue liner at once, not just the one you use.
- Missing or undersized caps causing cross-contamination between units. In a three-flue stack, an uncapped flue lets rain in, which turns to steam and drives acidic vapors into adjacent flues. We’ve documented cases where a neighbor’s abandoned coal flue was the source of water damage in a different unit’s gas flue.
- Improperly sized gas flue caps restricting draft. Converted triple-deckers often have gas furnaces venting into flues that were built for coal. A cap that’s too small or a termination that’s too restrictive makes combustion gases back up into living spaces. Crawlspace or attic detectors are not a substitute for a properly sized termination.
- Animal entry through open flues on shared stacks. Birds, squirrels, and raccoons treat an open flue on a New Britain triple-decker as an invitation. In a shared stack, once animals nest in one flue, the debris and odor affect the units above and below. A properly sized cap with the right screen size stops it.
Pricing for Chimney Cap & Crown in New Britain, CT
Here’s what you can expect in New Britain’s market. A standard single-flue cap installation runs $340-$650. Cap replacement with a stainless or copper cap is $450-$900 depending on size and material. Crown repair with a Gelco coat starts at $600 for a minor crack repair and runs up to $1,400 for a full recrown on a standard chimney. For multi-flue stacks on triple-deckers, which are structurally the majority of New Britain chimneys, expect $900-$3,800 depending on how many flues are active and what kind of cap the stack needs.
What moves the price is flue count, access, and condition. A three-flue stack with spalling brick and a cracked crown costs more than a single-flue cap because the work is structurally different.

FAQs - Chimney Cap & Crown in New Britain
We size each flue termination to the appliance it serves and the flue’s actual interior dimensions. On a three-flue stack, each opening is measured and capped separately, often with a custom multi-flue cap built to seal the crown while leaving each termination appropriately open. For converted gas flues, we verify the termination doesn’t restrict draft below the appliance’s minimum. That’s the difference between a cap that protects and a cap that causes spillage in a tightly sealed unit. Call (980) 580-8641 to have your stack scoped before any work is quoted.
Freeze-thaw cracking. The original crowns on most 1920s New Britain chimneys were sloped mortar, not Portland cement, and soft lime mortar spalls heavily in Hartford County winters. Once the crown cracks, water enters the stack and attacks the flue liners. The fix is a Gelco crown coat over a properly rebuilt crown, which flexes with the chimney instead of cracking like the original mortar. In two-family homes, we often find the neighbor’s side of the crown has failed before the owner’s side, which is exactly why we recommend treating the crown as one structure, not two halves.
No. A cap on your flue does not isolate your flue from an adjacent flue in the same masonry stack. If the neighbor’s flue leaks combustion gases into the shared brick mass, that gas can migrate through cracks into your flue or into the wall cavities between units. This is a structural and safety issue that requires a camera inspection of the entire stack, not just your flue. We document every flue in the stack on multi-unit jobs, because the cross-contamination risk is real and a cap on one flue doesn’t solve it. Bring us your landlord’s contact or your neighbor’s, and we can scope the whole stack at once.
Yes. Gas flues need a cap that keeps rain and animals out but does not restrict the draft any more than the manufacturer’s minimum. Many newer gas furnaces vent at lower temperatures and lower pressure than the coal or oil appliances they replaced, which means a cap that worked fine for oil might be too restrictive for gas. We size gas terminations by the appliance spec, not by habit. On New Britain’s converted triple-deckers, where most flues have been through multiple fuel conversions, this is one of the most common draft problems we fix.
Every year, before heating season. New Britain’s freeze-thaw cycle and the age of the city’s brick stacks mean crowns crack and caps rust on an annual timescale, not a generational one. Haven Standard Clause 4 requires a photo record on every inspection, so you can see the crown and cap condition with your own eyes, year over year. If you’ve never had your multi-flue stack scoped, call (980) 580-8641. We’ll inspect all flues in the stack, not just the one you think is the problem.
Key Takeaways
- New Britain’s pre-WWII triple-deckers and two-families often have three flues in one stack, each with its own fuel-conversion history.
- A cap on one flue does not protect you from a neighboring flue’s leaks or cross-contamination.
- Crown failures from freeze-thaw are the most common problem on these older brick stacks, and they damage all flues in the stack at once.
- Written price before work starts, photo record when it’s done, 365-Day Done Right Promise on every job.
