# What NFPA 211 actually is
NFPA 211 is the National Fire Protection Association's standard for chimneys, fireplaces, vents, and solid fuel-burning appliances. It's not law in Nassau and Suffolk — but it's the reference every CSIA-certified sweep, insurance adjuster, and building inspector uses. If you've had a chimney fire and file a claim, the adjuster will ask whether the chimney was inspected to NFPA 211 standard in the last 12 months. If the answer is no, expect an argument.
NFPA 211 defines three inspection levels. Each has a specific scope and a specific use case.
Level I: the annual inspection
Scope: visual inspection of all accessible portions of the chimney, connector, and appliance. Covers the exterior of the chimney, the firebox, the smoke chamber, and accessible portions of the flue. No special tools beyond a flashlight and a brush.
When you need it:
- Your system hasn't changed since last inspection
- You're continuing to use your fireplace as you always have
- Annual service before burn season
What a Long Island Level I costs: $195-$275, usually bundled with an annual sweep at $249-$395 total.
Level II: the camera inspection
Scope: everything in Level I, plus a video camera scan of the entire flue from top to bottom, plus inspection of accessible portions of the attic, crawl space, and basement where the chimney passes through.
When you need it (NFPA 211 requires Level II):
- Property transfer. Buying or selling a home in Nassau or Suffolk with a fireplace? Most real estate attorneys and buyer inspection contingencies require a Level II. This is the inspection that finds cracked flue tiles you can't see from the firebox.
- Fuel type change. Converting from wood to gas, oil to gas, or any fuel swap? Level II required before first use with new fuel.
- After a chimney fire. Even a small one. The flue tiles may be cracked even if the fire seemed minor.
- After an earthquake, lightning strike, or significant roof event. On Long Island this is usually hurricane or nor'easter damage.
What a Long Island Level II costs: $395-$550. Takes 75-90 minutes on site.
Level III: the invasive inspection
Scope: opens up concealed portions of the chimney structure — removing siding, drywall, or masonry — to access areas that can't be seen in Levels I or II. Usually required when a Level II found strong evidence of hazardous conditions.
When you need it:
- Level II found suspicious damage in a concealed area
- Insurance claim adjuster requested it
- Selling or buying a home where a serious defect is suspected
What a Long Island Level III costs: varies widely — $650-$2,500+ depending on how much demolition is required. Often insurance-covered if the trigger was storm damage.
The most common Long Island mistake
Homeowners selling a house in Levittown or Garden City call us for "an inspection" and expect Level I. When we explain the closing almost certainly requires Level II, they push back on the price difference. Then the buyer's attorney insists, the seller pays anyway, and we come back out a week later for the Level II.
If you're selling, ask your real estate attorney specifically what level of chimney inspection the contract requires. It's usually Level II. Book that one the first time.
What we document
For every inspection level, our written report includes:
- All photos and camera footage
- Flue condition by section (top third, middle third, bottom third)
- Creosote stage and approximate volume
- Any cracks, spalling, or water damage
- Chimney cap, crown, and flashing condition
- Draft performance (on Level II, we measure)
- Specific NFPA 211 violations if any
- Repair recommendations with rough cost ranges
This is the document your insurance adjuster wants. This is the document real estate attorneys accept. This is the document you keep in your house file.

We do all three levels on Long Island. Book online and tell us the context — annual, pre-sale, post-fire, fuel conversion — and we'll bring the right gear and write the right report.
