What a Tier 2 Inspection Includes — Camera, Report, and Images
A Tier 2 chimney inspection is a camera scan of the flue interior with a written report and still images attached.
It is the inspection level that satisfies the documentation requirements most commonly requested by NYC co-op boards, mortgage lenders, and buyers’ attorneys before a property closes. A Tier 2 goes beyond what eyes can see from the firebox opening. The flue camera captures the liner surface from the firebox floor to the crown — revealing cracks, offset joints, debris accumulation, and blockages that a visual inspection cannot confirm.
The result is a written document, not a verbal summary. It includes still images captured during the scan. That document is what the co-op board, lender, or attorney needs — not a cleaning receipt.
Camera Scan
A video and still-image capture system inserted from the firebox or chimney top, working systematically through the liner surface from base to crown.
Written Report
Formatted document listing the inspection date, technician findings, deficiencies noted with location, and a condition summary. The deliverable co-op boards and attorneys recognize.
Still Images
Photographs captured directly from the camera footage and attached to the report — visual documentation of any condition the scan identifies.
Co-Op Boards and Lenders in NYC Increasingly Require This Document
NYC real estate transactions move fast — and chimney inspection requirements often show up late.
Here’s what most homeowners don’t realize about the closing process: the request for chimney documentation can arrive two or three weeks before the scheduled closing date. The fireplace hasn’t been used in years. Nobody knows when the flue was last looked at. The lender’s underwriter flags it. The co-op board’s managing agent says they need documentation before the unit transfers.
This happens across the Brooklyn and Queens corridors. It happens on brownstone sales, co-op conversions, and estate transfers. The co-op board may have had no chimney policy last year and introduced one this year.
A real estate transaction chimney report — the written output of a Tier 2 inspection — is the document that satisfies all three parties at once. One inspection. One report. One clear deliverable that moves the transaction forward.
Who Requests Tier 2 Documentation
Co-Op Boards
Managing agents and board policies increasingly require chimney documentation before unit transfer.
Mortgage Lenders
Underwriters flag chimney condition during pre-closing review and request the written report.
Buyers’ Attorneys
Closing attorneys hold transactions pending until the written inspection document is produced.
The Closing That Almost Got Derailed by the Wrong Inspection Type
Scheduling the wrong inspection type is a problem no one discovers until the closing is already on the calendar.
Here is a scenario Prime Chimney encounters regularly in Brooklyn and Queens. A seller needs a chimney inspection before closing. They book a cleaning. The technician arrives, sweeps the flue, and leaves a receipt. The seller brings the receipt to the closing table.
The co-op board’s managing agent says it isn’t sufficient. They asked for a chimney inspection report with documentation of the flue interior. A cleaning receipt doesn’t satisfy that. Neither does a Tier 1 visual summary, which records what can be seen from the firebox opening but does not include a camera scan.
The closing gets delayed. The buyer’s attorney puts a hold on the transaction until the correct document is produced.
A Tier 2 inspection — a camera scan of the flue with a written report and still images — is what the managing agent actually needs. The terminology matters. Co-op boards and lenders in NYC increasingly specify Tier 2 language in their documentation requirements, but sellers often don’t encounter that language until a week before their scheduled closing date.
That’s exactly the timeline Prime Chimney Sweep & Repair is built to work within. We schedule, scan, and deliver the written report on the day of the inspection. Not mailed two weeks later. Not emailed in three to five business days. The day of the visit.
We Deliver the Written Report the Day of the Inspection
Same-day written report delivery is standard on every Tier 2 real estate inspection we perform.
A closing timeline doesn’t allow for delays between the inspection visit and the documentation. The report needs to be in the attorney’s hands — or the managing agent’s hands — within the same business day the scan is completed. That is how Prime Chimney operates on every Tier 2 inspection tied to a real estate transaction.
The written report includes still images captured from the flue camera scan. It identifies the condition of the liner, notes any deficiencies found, and is formatted to meet the documentation standard that co-op boards and real estate attorneys in NYC most commonly request. This is not a handwritten note. It is not a verbal summary. It is a formatted written document that names what the camera found.
If a deficiency is identified during the scan, that finding is documented in the report — clearly, with images — so the seller, buyer, and their respective attorneys understand exactly what was found and what it means for the transaction.
How the Camera Scan and Written Report Are Conducted
The Tier 2 process covers the flue from the firebox floor to the crown — every accessible section.
The technician begins with a brief visual check of the firebox opening, damper condition, and throat area. This confirms that the flue is accessible and that the camera can enter safely.
The flue camera — a video or still-image capture system — is inserted from the firebox end or the chimney top, depending on flue geometry and building access. It captures the liner surface systematically, working through each section of the flue interior.
The written report is compiled from the camera footage and still images captured during the scan. It includes the inspection date, the technician’s findings, any deficiencies noted with their location in the flue, and a condition summary.
What the Camera Documents
Six specific conditions captured during every Tier 2 scan
Liner Cracks & Fractures
Cracks, fractures, or missing mortar between tile joints — captured directly on the liner surface from inside the flue.
Offset Joint Failures
Sections where liner tiles have shifted out of alignment, creating ledges where debris and creosote accumulate.
Debris Accumulation
Especially at bends or at the base of the flue. The camera reveals it clearly, with location recorded for the report.
Crown Condition
The crown at the top of the flue, visible through the upper camera position — cracks, deterioration, or missing material noted.
Prior Chimney Fire Damage
Evidence of glazed or deeply embedded creosote residue on the liner walls — a finding that materially affects fireplace use safety.
Blockages
Anything that would prevent safe fireplace use — animal nests, fallen masonry, foreign objects, or blocked flue sections.
What Common Deficiencies Look Like in NYC Pre-War Flues
Knowing what a camera scan typically finds helps buyers and sellers prepare before the inspection is scheduled.
NYC pre-war buildings — brownstones, row houses, and converted apartments — share a consistent set of chimney conditions. These are the findings that come up most often during Tier 2 scans on these properties.
Deteriorated Clay Tile Liner Joints
Pre-war clay tile liners are assembled from sections with mortared joints that erode over decades. A camera scan shows them as gaps or recesses between tile sections. Minor erosion is common — significant gaps opening into surrounding masonry are reportable.
Mortar Debris at Flue Bends
Pre-war NYC flues often include offsets — angled sections that route around framing or through a multi-story building. Debris accumulates at the low side of these bends. The camera reveals it clearly with location captured for the report.
Missing or Deteriorated Damper Plates
The camera confirms damper condition from above. In older NYC buildings, the damper plate is frequently absent, corroded, or warped open — a condition that affects energy efficiency and must be disclosed in the report.
Crown and Cap Condition
The upper camera position shows the crown surface and the cap, or its absence. A cracked crown or missing cap is a common finding in pre-war buildings where rooftop maintenance has been deferred.
Sellers benefit from knowing these deficiencies are common — and that their presence in a report does not automatically derail a transaction. The report establishes condition, which buyers and their attorneys can evaluate on the merits.
