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.

We’re Alcott Chimney Sweep, led by Ruben Castellano. We’ve been inspecting and repairing chimneys since 2002, and we built this company around one idea: you should know exactly who’s coming to your door and exactly what you’re paying before anyone steps inside your New York City home.

- You’ll know your technician’s name and see their photo before anyone knocks on your door.
Why Alcott Chimney Sweep Is New York City’s Preferred Chimney Inspection Company
New York City homeowners don’t hand out trust easily, and we respect that. Every Alcott technician passes a background check and identity verification before ever setting foot on a New York City property. This is the Threshold Standard, and it’s not an optional upgrade. When you book with us, you’ll know the technician’s name and see their photo before we arrive. The person at your door will match that photo. No exceptions.
That matters in a city where opening the door to a stranger is a genuine decision, especially for older homeowners and parents with young kids. Ruben Castellano built Alcott on the idea that trust gets proven before the truck pulls up, not after. Alongside that, every inspection includes a written price before any work begins. No surprises at the end of the job, ever.
We also answer the phone. A live person picks up, around the clock. If you smell smoke at 11 p.m. in a New York City apartment and don’t know whether it’s a chimney problem or something worse, you’ll talk to a human being immediately, not a voicemail queue.
Chimney Inspection Services in New York City
Chimney Inspection Services in New York City cover three levels defined by the National Fire Protection Association, and the right one depends on what’s happened to your chimney and what you plan to do next. A Level 1 inspection is the annual checkup: we examine the accessible portions of the flue, damper, firebox, and exterior chimney with a flashlight and standard tools. A Level 2 adds video camera scanning of the full flue interior, which is what a brownstone sale or a past chimney fire requires. A Level 3 involves opening a section of the chimney or wall when we suspect hidden structural damage.
Level 1 and Level 2 Inspections
For a New York City homeowner using a wood-burning fireplace each winter, a Level 1 inspection runs $179 – $249. If you’re buying or selling a brownstone in Brooklyn or a co-op in Manhattan, the buyer’s attorney will almost always require a Level 2 inspection, which runs $349 – $549 and includes the camera scan. We’ll tell you which level you actually need. We don’t upsell a Level 2 just because we have the camera on the truck.
Real Estate Inspection
When a New York City property changes hands, the chimney is frequently the last system anyone checks. That’s a mistake. A sealed-off fireplace in a Harlem townhouse or a boiler vent in a Queens co-op can hide thousands in deferred repairs. Our real estate inspections produce a written report with photos you can attach to the closing documents, and we’ll flag code issues like an unlined coal-era flue serving a modern gas boiler.

Chimney Flue Inspection in New York City
Chimney Flue Inspection in New York City is the part of the job that looks at the liner itself, the vertical passage that carries smoke and combustion gases out of your building. In a pre-war brownstone, that liner is often the original clay tile from 1905, or worse, unlined brick. We push a camera up the flue to check for cracked tiles, gaps, creosote buildup, and liner separation, and you get the photos.
Camera Inspection
Camera inspection is the single most valuable service we offer to New York City homeowners. Without it, a chimney sweep can’t see the middle third of your flue. With it, we can show you exactly what’s happening: a cracked tile behind the smoke chamber, a bird’s nest at the midpoint, a corroded cap letting rain straight into the flue. The photos go in your report. You’ll never be asked to approve a liner replacement on faith. If we recommend a repair, you’ll see the image that justifies it.
Flue Liner Evaluation
We evaluate flue liners against current New York City code, not just against what passed inspection in 1920. That’s the gap. The city’s Department of Buildings now requires correctly sized, properly lined flues for gas appliances, but thousands of pre-war buildings still have the original oversized coal-era flues in place. We’ll tell you, in plain English, whether your liner meets code, what a HeatShield resurfacing would cost versus a full DuraFlex stainless reline, and whether you can safely defer the work.
Trusted Brands We Service in New York City
We stock and install professional-grade trade materials for New York City homes, including HeatShield resurfacing systems, Gelco caps and dampers, Famco flashing components, and Olympia Chimney liners. These are the brands a chimney professional specifies, not box-store substitutes. A cast-iron cap from a hardware store lasts three years at a Brooklyn roofline; a stainless Gelco unit lasts a generation. When we inspect your chimney in New York City, we’ll tell you which components are worth replacing now and which can wait, and we’ll give you a written price before any work starts. We keep common parts in our New York City stock, so most repairs don’t wait on a shipment.
Common Chimney Inspection Problems We See in New York City Homes
- Salt-corroded caps and flashing on rowhouse rooflines. Salt-laden coastal air reaches brownstone rooflines across the five boroughs, corroding galvanised caps and flashing far faster than the masonry around them. A bead of salt bloom around a cast cap’s threads is a tell that the metal is giving out. We quote stainless replacement when we see it.
- Rust-jacked mortar joints from failing flashing. When galvanised flashing corrodes, it expands and physically pushes against the surrounding brick, opening mortar joints and letting water into the chimney. This is a New York City pattern we see on nearly every pre-war rowhouse inspection.
- Freeze-thaw spalling in the exposed brick above the roofline. The city’s temperatures swing above and below freezing from November through March, and water trapped in brick pores expands each time it freezes. The bricks above your roofline take the worst of it. An inspection catches spalled brick before the crown cracks wide enough to let water into the flue.
- Unlined or misidentified shared flues in tenement buildings. In a multi-apartment building in neighborhoods like Bed-Stuy or Harlem, several fireplaces or gas appliances often share a single chimney stack. Figuring out which flue liner serves which unit requires a camera and a careful eye. A Level 1 inspection from a generic company won’t catch a mislabeled flue. We will.
Pricing for Chimney Inspection in New York City, NY
A Level 1 chimney inspection in New York City runs $179 – $249. A Level 2 inspection with a full camera scan runs $349 – $549, and that’s the one New York City real estate attorneys typically require before closing. A Level 3 inspection, which involves opening part of the chimney or wall, starts at $549 and is priced based on the access work involved. Here’s what affects your number: whether the chimney serves a fireplace, a gas boiler, or both; how many flues we’re inspecting; and whether we can access the roofline from a standard ladder or need a lift. Every inspection includes a written report with photos at no extra charge. Call (336) 863-3889 for a free estimate, and you’ll have a firm price before anyone sets up a ladder.

FAQs About Chimney Inspection in New York City
Yes. A gas boiler venting through a pre-war brick flue is one of the most overlooked safety risks in New York City housing. Gas exhaust is full of moisture and slightly acidic condensate, and in an unlined coal-era flue that moisture soaks into the brick, slowly eating the mortar and creating blockages. An annual inspection catches liner degradation, bird or squirrel nesting, and carbon monoxide venting problems before they become dangerous. The city’s pre-war housing stock makes this a year-over-year concern, not a once-a-decade one. Call (336) 863-3889 to book a Level 1 inspection and get a written report with photos.
A Level 2 inspection, without exception. If a brownstone fireplace hasn’t been used in years, or if you just bought a building and don’t know its chimney history, a Level 1 flashlight check isn’t enough. A Level 2 inspection includes a full camera scan that shows cracked tiles, missing mortar, creosote buildup, or a sealed-off flue that a Level 1 would miss. In New York City, nearly every brownstone fireplace we inspect has some combination of coal-era debris, old bird nesting, and mortar spalling. Expect to pay $349 – $549, and you’ll have photos showing exactly what we found.
Salt. Salt-laden coastal air blows across the five boroughs and settles on metal components at roofline height. Galvanised caps and flashing corrode from the outside in, developing a white salt bloom and pitted threads long before the surrounding brick shows any wear. A cast cap that would last 15 years inland can fail in seven or eight years at a New York City roofline. We replace corroded components with stainless steel units, which resist salt far better than galvanised metal, and we’ll give you a written price before any work begins.
Yes, and we do it routinely. During gut renovations in neighborhoods like Crown Heights, Bushwick, and Central Harlem, contractors frequently uncover fireplaces that were sealed shut for 40 to 60 years. Those flues are usually full of collapsed mortar, coal-era soot, and animal nesting. We’ll bring a camera to the job, open only what’s needed for access, and document the condition inside. Then we’ll give you a written report and a straight answer about what it would take to bring that fireplace back into service safely.
A proper inspection covers every flue served by that shared stack, not just the one you asked about. In a pre-war New York City building with a gang flue system, multiple apartments may share a single chimney structure, and the flue liners for each unit run side by side inside it. We identify which flue belongs to which apartment, check each liner independently with a camera, and report any cross-flue leakage or mislabeled venting. If a gas appliance is venting into the wrong flue, or a liner is cracked behind another tenant’s wall, you’ll know it. This is a service a national chain rarely performs correctly. Call (336) 863-3889 for an inspection that accounts for the full stack.
