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.

Why Flint Chimney Sweep Is New York City’s Preferred Chimney Inspection Company
New York City housing stock does not behave like suburban chimneys. Brownstone and rowhouse flues share masonry stacks, run through parapet walls, and have been exposed to a century of freeze-thaw cycles. Our New York City Chimney Sweep technicians know what that looks like from the inside, because they have inspected thousands of these stacks across Brooklyn, Queens, Manhattan, and Staten Island. We do not guess at what might be happening behind brick. We run a camera and show you the photos.
Every inspection we perform in New York City is done by a background-checked, uniformed technician who arrives inside the window we give you. You know exactly who is walking through your door. The price is written before the work begins, and it is the price on the invoice. That standard is non-negotiable, and it is the same Garrison Standard every Garrison Partners location follows.
Hank Delano leads our team, and the expectations are simple: show up on time, document everything, and stand behind the work. If a covered repair fails within one full year, we return at no charge under our 365-Day Done Right Promise. No argument, no restocking fee, no re-diagnosis charge. Call (830) 251-4560 and a live person answers, 24 hours a day.
Chimney Flue Inspection in New York City
Chimney Flue Inspection in New York City means running a camera through the entire length of the flue that carries smoke from your fireplace, boiler, or furnace out of the building. In a brownstone, that flue may be shared by multiple apartments, which means the inspection has to trace which firebox connects to which flue, and verify there is no cross-drafting between units. A typical flue inspection here runs $189 – $350 for a Level 1, and $350 – $500 for a Level 2 camera inspection when the property is changing hands or after a suspected issue.
What the camera sees
We lower a high-resolution camera down the flue from the roof or through the firebox, documenting every foot on video. In New York City’s older masonry stacks, the camera commonly finds spalled clay liner sections, mortar joints that have opened up, or a flue that was never lined at all. You get a photo report you can actually read, not a verbal summary you have to trust.
When it is required
A Level 2 camera inspection is the smart call when you are buying or selling a brownstone, co-op, or rowhouse, or after any chimney fire, building settlement, or change in fuel type. If you just moved in and the previous owner has no records, book the camera. It costs a few hundred dollars and tells you whether you have a working flue or a liability hiding behind the mantel.
Chimney Fire in New York City
Chimney Fire in New York City is a real risk even in homes where the fireplace is mostly decorative, because creosote builds up in flues that are undersized, unlined, or shared across units. A chimney fire happens when that creosote ignites, and in a brownstone stack, that fire can spread behind walls before anyone sees flames. An inspection that identifies creosote buildup and liner damage before ignition typically costs $189 – $350, and it is the cheapest insurance a New York City homeowner can buy against a five-figure masonry rebuild.
What creosote does to a shared stack
In a shared brownstone flue, creosote from one apartment’s fireplace accumulates in the same stack that serves another apartment. If the flue serving the parlor floor has third-degree glaze creosote, the fire risk belongs to everyone on that stack, not just the unit doing the burning. We photograph the creosote and show you exactly where it sits.
Signs one is already brewing
A strong campfire smell in rooms nowhere near the fireplace, a low rumbling sound from the chimney during a burn, or black flakes falling into the firebox are all signs of a chimney fire in progress or one that just happened. If you have had any of these, stop burning and call (830) 251-4560. We will inspect before you light another fire.
Trusted Brands We Service in New York City
We work with professional-grade materials from Gelco, Olympia Chimney, and HeatShield, because the job dictates the product, not the margin. When a New York City inspection reveals a cracked flue or a failed liner, we specify the repair with the right material for that specific stack, whether it is a HeatShield resurfacing application, a Gelco cap, or an Olympia Chimney stainless liner. Parts are ordered before we start the repair, so there is no three-week gap between diagnosis and fix. You approve the written price for the material and labor before anything is ordered. Call (830) 251-4560 and we will walk you through what your chimney actually needs.
Common Chimney Inspection Problems We See in New York City Homes
- Shared flue cross-drafting between brownstone units. The flue serving the parlor fireplace may be drawing smoke into the apartment above it, a condition that only a camera run on the shared stack can confirm. We trace each flue from firebox to termination and document any cross-connection in the report.
- Freeze-thaw damage to parapet-wall crowns and caps. New York City’s freeze-thaw cycles have cracked thousands of chimney crowns and caps on rooflines, letting water and animals into the flue between burns. A missing or cracked cap on a shared stack is one of the most common findings we photograph during inspections.
- Third-degree creosote hiding below the brush line. A standard sweep reaches the flue walls the brush can touch, but glaze creosote forms lower down where the brush cannot reach. We have found visible first-degree creosote at the top of a New York City flue covering third-degree glaze at the smoke chamber, and only the camera showed it.
- Unlined flues in pre-war rowhouses. Many New York City rowhouses built before 1940 have flues with no clay liner at all, just exposed brick and mortar that erodes with every heating season. We flag unlined flues as a priority finding and give you a straight answer on whether the repair can wait or needs to be scheduled.
Pricing for Chimney Inspection in New York City, NY

FAQs About Chimney Inspection in New York City
Once a year, every year, for any flue that is actively used, and once before you buy or sell any property with a fireplace, boiler, or furnace venting through a chimney. In New York City, where flues are often shared and older than the buildings around them, annual inspection is the only way to catch liner damage or creosote buildup before it becomes a fire or carbon monoxide problem. Call (830) 251-4560 and we will schedule the inspection at the written price you approve in advance.
A Level 1 inspection covers the accessible portions of the chimney: the firebox, damper, flue interior from the top and bottom, and the exterior stack and cap where reachable. A Level 2 adds a full camera scan of the flue interior and is required during any real estate transfer in New York City. A Level 3 involves opening up concealed areas of the chimney, usually after a chimney fire or a major structural question, and is the most expensive because we have to remove and replace access material. In a brownstone, the Level 2 camera run is where we find the problems that visual inspection misses between shared flues.
You can, but in New York City that is a gamble on a shared flue stack you have never seen from the inside. We have inspected brownstone flues that had never given the owner any trouble and found missing liners, open mortar joints, and cross-drafting into the apartment next door. The camera costs a few hundred dollars. The repair it catches before a fire is almost always cheaper than what you spend after one. Call (830) 251-4560 and we will run the camera and show you the photos.
Yes, and in some ways more so, because decorative fireplaces are often used rarely enough that creosote builds up unchecked for years, and the flue may never have been inspected since the building was converted. A chimney fire in a shared New York City stack does not care whether the fireplace is used for ambiance or heat. The creosote ignites either way, and the fire travels behind brick where it is hard to reach. An annual inspection catches it before it has fuel.
Your report includes the video footage, still photos of every finding, a written summary of what we found in plain words, and a prioritized list of what needs attention now and what can safely wait. We are direct about the difference between a cracked crown that should be addressed this season and a cosmetic spall that can wait a year or two. Nothing goes into the report as urgent unless the camera evidence supports it, and you approve any repair price in writing before we do the work. Call (830) 251-4560 for an inspection that tells you the truth about your chimney.
