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.
Fast, Reliable Fireplace Services Across Tremont
If you own or manage a building in Tremont, you already know the chimney stack out back wasn’t designed for what NYC now requires of it. Most of these pre-WWII brick walk-ups share a single masonry flue built for a #6 oil boiler, and the city’s Clean Heat mandate means that flue has to change before the boiler can. Emberly Chimney Cleaners handles fireplace and flue work across Tremont every week: gas fireplace service, inserts, dampers, fireboxes, and the oil-to-gas conversions that trip up so many building owners. We work from a documented camera inspection, we quote in writing before any work starts, and you can reach a live person at (980) 580-8641 any hour. That’s not a call center script. That’s us, answering.
Key Takeaways:
- Fireplace service in Tremont typically runs $180-$340 for a standard cleaning and inspection, $600-$1,400 for damper repair, and $3,800-$7,500 for a full flue relining with a stainless liner, depending on stack height and access.
- If your building is converting from oil to gas under NYC’s Clean Heat mandate, a camera inspection and relining are usually required before the DOB issues a certificate of approval.
- We don’t recommend any repair without camera evidence you can see for yourself. No photo, no work order. That’s Clause 4 of the Haven Standard, and it’s been our practice since 2009.
- Every job is quoted in writing before we start, and every job is backed by our 365-Day Done Right Promise.

Why Emberly Chimney Cleaners Is Tremont’s Preferred Fireplace Services Company
The buildings in Tremont were mostly put up between 1910 and 1945. That means the chimneys we work on are 80 to 115 years old, and they were built for fuel oil, not natural gas. Our Fireplace Services team knows what that means in practice: unlined flues, deteriorated clay tiles, heavy fuel-oil residue, and chimney crowns that have been through a hundred Bronx winters of freeze-thaw cycling. We name what we find, show you the camera footage, and quote a written price before anyone touches a brick.
Corrine Halstead runs Emberly Chimney Cleaners, and she’s built the company around a rule that most of the industry still ignores: the customer sees the evidence before the estimate. Over 38,000 chimneys inspected and cleaned since 2009. Every one with a documented photo record. Every one with a written scope and a written warranty before work started.
Our crews are background-checked and uniformed. You get a named technician, a text when they’re on the way, and a live person on the phone 24 hours a day. No voicemail, no web form, no “we’ll get back to you.” When a Tremont super calls about a shared stack with a cracked flue tile at 7:00 a.m., a human picks up.
Our Fireplace Services Services in Tremont

Gas Fireplace Service
Gas fireplaces in Tremont apartments and private homes need more than an annual glance. We clean burner assemblies, check gas connections for leaks at every joint, verify ignition and flame sensor operation, and run a camera down the flue to confirm the vent is drafting properly. A gas fireplace service in Tremont typically runs $180-$260 for the standard annual service, and if you’ve just converted from oil, we pay extra attention to the liner because gas exhaust is cooler and wetter than oil exhaust, and it condenses aggressively inside an old masonry flue.

Wood Burning Fireplace
Wood burning fireplaces in Tremont are less common than in the suburbs, but when they exist, they’re usually in larger pre-war units that kept their original hearths. We sweep the flue, inspect the firebox for cracked refractory panels, check the damper for full travel, and document creosote stages. Class III creosote, which is the hard, shiny, tar-like form, needs chemical treatment before mechanical removal, and we find it more often in Tremont fireplaces that burn pressed logs than in any other fuel type. A sweep and Level 2 camera inspection runs $220-$340 in Tremont.

Fireplace Insert
Installing a gas or wood insert into a Tremont pre-war fireplace usually means the existing flue is too large, too old, or too damaged to vent the insert safely. A fireplace insert installation in Tremont typically runs $4,200-$7,800 depending on the unit and whether a stainless liner is required, and it almost always is. We measure the flue, show you the camera images, and explain exactly why the liner is needed before we ask you to sign anything. Materials come from DuraFlex and Copperfield through Haven’s buying network, so the price you see is the price we got, not a markup on a markup.

Damper Repair
Dampers in old Tremont hearths are often rusted open, rusted shut, or missing entirely because a previous owner removed them to improve draft, which then let conditioned air escape up the chimney year-round. We replace top-sealing dampers, repair or replace throat dampers, and convert old pivot dampers to cable-operated units. Damper repair in Tremont typically runs $600-$1,400 including parts, labor, and a camera check of the flue above the damper. It’s one of the highest-ROI fireplace repairs in this city because a proper seal cuts the draft that pulls heat out of the apartment all winter.

AfterTrusted Brands We Service in Tremont
We stock and install parts from manufacturers that have proven themselves on Bronx chimneys: HeatShield for resurfacing deteriorated flues, Gelco for chimney caps and chase covers, and DuraFlex for stainless flue liners. Because we keep common liner diameters and cap sizes on hand, most Tremont jobs don’t wait on a parts delivery. If you’ve got an older gas fireplace insert from a brand that stopped supporting its parts, we’ll tell you that directly and give you a written estimate for replacement or for what can actually be repaired. No brand loyalty that costs you money.
Common Fireplace Services Problems We See in Tremont Homes

- Oil-to-gas conversion without relining: A gas appliance vented into an oversized, unlined oil flue produces acidic condensation that eats the interior masonry within a few seasons. The DOB won’t issue a certificate of approval for an unconverted flue, and we see failed conversions in Tremont regularly. We reline with a properly sized stainless liner before the new burner fires.
- Shared flues with hidden damage: A five-story walk-up off East Tremont Avenue has one stack, one flue, and dozens of tenants. A crack in one clay tile can leak carbon monoxide into multiple apartments, and no one knows until a camera inspection finds it. We recommend camera inspection of any shared Tremont stack at least every two years.
- Tar-like glaze from decades of #6 oil: This isn’t wood creosote. It’s a dense, glossy residue from heavy bunker-oil combustion, and it has to be chemically treated and removed before any relining or conversion. If it isn’t, it off-gasses noxious fumes the first time the new burner fires. Tremont sweeps budget extra time for this because Tremont has more of it than any neighboring market.
- Spalled crowns and open mortar joints: Bronx winters do freeze-thaw cycling on every exposed chimney crown in Tremont. By spring, we see crowns that have lost chunks of concrete and mortar joints that let water into the stack. The fix is a rebuilt crown and repointing, but the timing matters: do it before heating season, or you risk carbon monoxide drafts through holes you can’t see from the street.

FAQs - Fireplace Services in Tremont

Yes. A camera inspection is the minimum acceptable documentation, and in practice, a relining is almost always required before the DOB issues a certificate of approval for an oil-to-gas conversion in Tremont. The issue is that the existing flue was sized for #4 or #6 fuel oil, and a gas burner vented into that oversized, unlined flue produces acidic condensation that spalls the masonry. We scope the flue, show you the footage, and quote the relining in writing before you file anything. Call (980) 580-8641 to schedule the inspection that starts the process.

That glaze is the combustion residue of #6 bunker oil, which heated thousands of Tremont apartment buildings for decades before NYC’s Clean Heat mandate began phasing it out. It’s denser and more chemically aggressive than wood creosote. Wood creosote can be swept with standard brushes; heavy fuel-oil residue usually requires chemical treatment and additional labor, which is why our Tremont estimates reflect the extra time. We remove it fully before installing any liner, because residue left behind off-gasses noxious fumes when the new gas burner first fires.

Every two years at minimum, and annually if the building has any history of water leaks, spalled masonry, or tenant carbon monoxide complaints. A shared stack serves dozens of people, and a crack in one flue tile can migrate into apartments that don’t even have fireplaces. Our recommendation for Tremont buildings is a camera inspection every heating season, even if the boiler hasn’t changed. The cost is small relative to the liability.

Almost never safely. A shared boiler flue is sized and routed for one specific appliance, and adding a wood-burning fireplace or insert creates draft competition, backdraft risk, and carbon monoxide exposure across multiple units. The honest answer for most Tremont apartments is no, and we’ll tell you that after a camera inspection, not after you’ve already bought the insert. If the building is being re-piped and each unit gets its own dedicated flue, that’s a different situation, and we’ll quote it in writing with a full documented plan.

Freeze-thaw cycling. Water enters the porous concrete crown during the day, freezes and expands at night, and the cycle repeats every winter until chunks of the crown spall off. Tremont’s exposed rooftops get the full force of Bronx winter weather, and 100-year-old mortar joints have already lost much of their original binder. We see the worst spalling on buildings off East Tremont Avenue where rooftop access is limited and crowns haven’t been repointed in 40 years. The fix is a rebuilt crown with proper overhang and drip edge, plus repointing of the top courses. Call (980) 580-8641 if you want a camera look at your crown before the next freeze cycle starts.
