Frequently Asked Questions

Once a year, before the first burn of the season, is the NFPA standard and the right cadence for most Manhattan homes. If you burn more than two cords of wood a season or burn unseasoned wood, sweep twice. In neighborhoods like Astoria and Long Island City where many homes have gas venting through the masonry flue, an annual check still matters because gas byproducts leave acidic residue that eats mortar. Manhattan's burn season runs roughly October through March. The smart window to book is August through October, before the rush. Call (862) 319-8047 to get on the calendar before the season fills up.

We protect the floor and hearth with drop cloths, run a HEPA-filtered vacuum, and sweep the flue with rotary brushes sized to your exact flue dimensions. Then the camera goes down. That's the part most Manhattan homeowners don't expect: the post-sweep camera scan to verify the walls are clean and document the chimney's interior condition. We note cracking, spalling, water staining, and mortar wear. You get a written report with photos and video of what we found. No one asks you to make a repair decision on the spot. The evidence goes to you, and you decide.

A standard single-flue cleaning in Manhattan takes 60 to 90 minutes from setup to final walkthrough. Double-flue jobs run closer to two hours. What adds time is roof access: in neighborhoods like the Financial District and Midtown where roof entry requires building approval or doorman coordination, we handle the logistics and factor that into the appointment window. You'll know the window before we arrive, who's coming, and we text when we're on the way. The Haven Standard's second clause, Arrive on schedule, is exactly that: a real window and a named tech.

It shouldn't be, and if it is, someone skipped setup. We run a HEPA vacuum the entire time the brush is in the flue. The fireplace opening is sealed before we start. Drop cloths go down on the hearth and the path to the door. Manhattan apartments and brownstones have tight spaces and white walls; we work accordingly. You won't find soot on the mantel or a film on the floors when we leave. If you ever do, that's a Clause 5 failure, and you tell us. We'll make it right.

Yes. Gas fireplaces and gas boiler flues still need cleaning in Manhattan, though for different reasons than wood-burning fireplaces. Gas combustion produces acidic condensation that corrodes mortar joints and flue tiles over time. The buildup is less visible but just as damaging. We sweep gas flues annually and run the camera to look for spalling caused by that acidic wear. If your building in Elmhurst or Flushing has gas appliances venting into a masonry chimney, the annual check is just as important as it is for a wood burner. The camera tells us what the acid is doing to the flue.

A Level 2 inspection is what NFPA 211 requires when you're selling a home, after a chimney fire, after an earthquake or seismic event, or when you've changed the appliance venting into the flue. It includes everything in a Level 1 look, plus a camera scan of the entire flue interior, and an inspection of accessible attic, crawlspace, and exterior portions of the chimney. In Manhattan real estate transactions, a Level 2 inspection is increasingly the standard ask from buyers, especially in brownstone neighborhoods like the Upper East Side and Morningside Heights. We include the camera scan in every cleaning, so if your buyer wants a Level 2 documented, we're already doing the core work.

Yes, and this is one of the smartest uses of a chimney company in New York. A pre-purchase Level 2 inspection gives you the camera evidence of what the flue actually looks like before you close. In Manhattan, where co-op and condo boards want documentation and brownstone buyers want leverage, we provide a written report with photos and video that becomes part of your due diligence. We serve buyers across the borough, from the Financial District up through Morningside Heights and into Astoria and Long Island City. Call (862) 319-8047 to schedule the inspection before your option period ends.

We install and service parts from Gelco, Olympia Chimney, and Copperfield, among others. Those three represent the most common types we see in Manhattan: Gelco for chase covers and caps, Olympia for liners and venting components, and Copperfield for masonry repair materials. We don't push one brand as a solution to everything. The flue dictates what fits, and the camera scan dictates what's needed. When we quote a liner or a cap replacement, the quote names the part and the manufacturer, so you can verify exactly what you're paying for before you approve it.

Three signs: the camera shows water intrusion stains running down the flue interior, you see rust or missing sections on the cap itself, or you hear animals. Manhattan rooftops are squirrel and bird territory, and a damaged cap is an open door. A proper cap keeps rain, animals, and debris out while letting the flue vent. We see a lot of Gelco and Olympia caps in Manhattan, and they hold up well against the city's weather, but no cap lasts forever. If your cap is rusted through or the mesh is torn, we'll show you in the video and quote the replacement in writing. You approve it before we order the part.

The right liner depends on what your flue is venting and its dimensions. For wood-burning fireplaces, stainless steel is the standard: durable, resistant to high heat, and clean to install. For gas furnaces and boilers, many Manhattan homes use an aluminum liner rated for the appliance's BTU output. Gelco and Olympia both manufacture reliable liner systems, and the choice between them often comes down to the specific flue dimensions and what's in stock. We'll show you the options after the camera tells us what we're working with. You'll see the quote for each option, in writing, before any liner is ordered.

Creosote is the black, tar-like residue that forms when wood smoke condenses inside a colder flue. It comes in three stages: flaky soot that brushes away easily, crunchy tar deposits that need mechanical removal, and glazed creosote that hardens into a shiny coating that burns hot and fast. That third stage is the fire hazard. A chimney fire is just creosote burning inside your flue at temperatures that crack tiles and warp liners. In Manhattan's older brownstones, where flues have been absorbing moisture and soot for decades, glazed creosote is common in fireplaces that haven't been swept in years. The camera scan during our cleaning shows us exactly what stage you're dealing with.

Yes. Every pro working under the Level Two Chimney name in Manhattan is required to hold the license and insurance their state and city require. We operate as an independently owned and operated business serving the city's five boroughs and nearby New Jersey communities including Jersey City and Englewood. The documentation is available on request, and we're glad to provide it, because Clause 3 of the Haven Standard is Verified crews: licensed, insured, background-checked, license number on the page. You're hiring people who will be in your home and on your roof. Ask us for the paperwork. We'll show it to you.

Every technician who works under the Level Two Chimney name goes through a background check as part of the standard we work to. Clause 3 of the Haven Standard requires it. The people we send into your Manhattan apartment or brownstone have been vetted, are licensed where the state requires it, and carry insurance. We know that letting someone into your home in this city is an act of trust, and we treat it that way. You'll know the name of the tech before they arrive, and they'll arrive in a company vehicle.

Yes. We work with co-op boards, condo associations, and building managers across Manhattan, from the Financial District up through Midtown and into the Upper East Side. Multi-unit chimney work in Manhattan usually means coordinating with building management for roof access, scheduling around residents, and documenting everything for the board. We're used to that dance. The camera scans and written reports we provide are built to satisfy board-level documentation requirements. If your building's managing agent needs a chimney inspection report for an insurance renewal or a sale, call (862) 319-8047 and we'll coordinate directly with them.

Stop using the fireplace immediately and open a window to vent the room. Smoke backing into the living space means the flue isn't drafting properly, and the cause could be a blockage, a closed damper, or a flue that's too cold to pull. It can also mean a structural issue inside the chimney. Don't try to diagnose it yourself, and don't light another fire until a professional has looked inside the flue. Call us at (862) 319-8047 during our business hours, Monday through Saturday from 7:30 AM to 7:30 PM and Sunday from 8:00 AM to 7:30 PM, and we'll get a camera down the flue to find out what's happening.

Our operating hours in Manhattan are Monday through Friday, 7:30 AM to 7:30 PM, Saturday 8:00 AM to 7:30 PM, and Sunday 8:00 AM to 7:30 PM. When you call, a live coordinator answers and connects you with the local team. If we have an opening the same day, we'll tell you, and we'll book it. For anything involving an active fire, smoke pouring into your home, or the smell of gas, call 911 first and call us second. A blocked or damaged flue is not something to wait on, but it's also not something to ignore. The camera will tell us what happened.

Skipping a cleaning for a year or two in Manhattan usually means creosote buildup, and the risk goes up the longer you wait. After three or more years, we're talking about stage two or three creosote, which is the flammable kind. If you burn regularly and haven't swept in years, the flue is a fire risk you can't see. There's also the carbon monoxide angle: a partially blocked flue in a home with gas appliances can push combustion gases back into the living space. The annual sweep is the cheapest insurance you'll buy all year. The alternative costs a lot more, and not just in dollars. Call (862) 319-8047 to book before the season.

Chimney cleaning is planned maintenance, but blocked flues become emergencies fast. If you smell smoke inside, see soot stains appearing above the fireplace, or hear animals in the flue, don't wait for the annual visit. Call us during our open hours, Monday through Saturday from 7:30 AM to 7:30 PM and Sunday from 8:00 AM to 7:30 PM. The coordinator who answers will connect you with the local team and we'll get a camera down the flue as soon as the schedule allows. For active fire or gas, the sequence is 911 first, then us.

A written record of the work, not just a handshake. The Haven Standard's first clause is Have it in writing: flat price, written scope, written warranty, before anyone starts. Your cleaning comes with a documented report of what we found, what we did, and what the camera showed. If anything in the flue needs attention, the photos and video are yours. We don't do verbal warranties that evaporate. If we install a part, like a cap or a liner, the manufacturer's warranty applies and we document it in your file. Every job leaves a written trail. That's the guarantee.

The Haven Standard is the five-part operating code every Level Two Chimney location agrees to work under. It's the reason the brand exists. Clause 1: Have it in writing, flat price, written scope, written warranty, before anyone starts. Clause 2: Arrive on schedule, a real window, a named tech, a text when they're on the way. Clause 3: Verified crews, licensed, insured, background-checked, license number on the page. Clause 4: Evidence on every job, photos and readings of what we actually found. Clause 5: No surprises, no door upsell, no scope creep, no "while we're in here." That's the standard we work to in Manhattan, and it's the reason our customers trust us.

Yes, and we do it with documentation, not with promises. The Level Two name comes from the NFPA 211 inspection standard: Level 1 is a look with a flashlight, Level 2 puts a camera down the flue. We work to the Level 2 standard on every job because it's the only way to actually know what's inside the chimney. When we finish a cleaning or inspection in Manhattan, you get the footage and the written report. If we installed a part, that's documented too, with the manufacturer and the warranty terms. We're not asking you to take our word for anything. We're showing you the evidence.

Your report includes the date of service, the flue measurements, the condition of the flue walls before and after the sweep, photos and video from the camera scan, and notes on anything that needs attention like cracked tiles, water staining, or cap damage. If we recommend a repair, we document why with the footage that shows the issue. You keep the report. It's yours. That documentation matters for insurance, for resale, and for peace of mind. Corrine Halstead runs our Manhattan operation, and she's built the team around this principle: say what you found, not what you felt about it. The report is the evidence.

Corrine Halstead leads the Manhattan team. She's the person behind the local operation, the trucks, the scheduling, and the standard we work to. When you book with us, you're booking with a local business that's independently owned and operated, working under the Haven Standard that Level Two Chimney Co. brought to this market. Corrine and her team know Manhattan's buildings, its roof access challenges, and the specific flue issues this city's older housing stock presents. Call (862) 319-8047 and talk to us directly.
