Chimney Inspection in North New Jersey
NFPA 211 defines three chimney inspection levels, and for a single flue on an ordinary single-family house with a walkable roof they run about $150 to $300 for Level 1, $250 to $650 for Level 2 with the camera scan, and $600 to $5,000 for Level 3. The standard calls for Level 2 on a house sale, not the level most quotes are written for.
Most people asking for a chimney inspection do not know they are asking for one of three different jobs. NFPA 211, the national standard the trade works to, defines three levels of inspection, and they answer progressively harder questions: is this system still fine to keep using the way it always has been, is it sound enough to hand to a new owner or to run after something has changed, and is there a hazard hidden inside the structure that can only be reached by opening it up. Booking the wrong one wastes money at best, and at worst gives a buyer a clean report on a flue nobody actually looked inside.
We inspect chimneys across New Jersey out of our Garfield shop, HIC reg.# 13VH13970900, with our own crew rather than subcontractors, and we scan the flue with a camera as a matter of course rather than as an upsell. That is the practical difference between a report that describes what could be seen from the hearth and one that describes the inside of the flue, and it is the line the standard itself draws between the first level and the second.
This page sets out what each level covers, which one fits the reason you are calling, and what the report gives you. Tell us what prompted it - a sale, a new furnace, a smell, a fire you have already had - and we will tell you which level that is before quoting. Call (201) 275-9185.

What NFPA 211's levels actually cover
The levels are cumulative: each one includes everything in the one below it and adds access. What separates them is how far the inspector is prepared to go to see the parts of the system that are not in plain view.
- Level 1 - the baseline, for a system that has not changed and is going to keep being used the way it always has been. The readily accessible portions of the chimney, structure and flue, and the appliance and its connection, checked for sound condition and no obvious obstruction or combustible deposits. No special tools, and no camera required by the standard.
- Level 2 - everything in Level 1, plus the accessible parts of the chimney exterior and interior including attics, crawl spaces and basements, the appliance and connector, and a video scan of the flue's interior. This is the level the standard calls for on a sale or transfer of the property, after an operating malfunction or an external event that could have damaged the chimney (a chimney fire, a lightning strike, an earthquake, a serious weather event), and whenever the system changes - a new appliance, a different fuel, a relined or resized flue.
- Level 3 - everything in Levels 1 and 2, plus the concealed parts of the structure. It is the level for when a serious hazard is suspected and cannot be confirmed any other way, and it means removal or destruction of permanently attached portions of the chimney or the building - a section of wall, a chimney crown - to get eyes on what is behind them. Nobody should be selling you this casually; it is what you do when the question is serious enough to justify opening the building.
Match the level to the reason you are calling
In practice almost every call falls into one of a handful of situations, and the situation decides the level rather than the budget:
- Nothing has changed and you want the annual check - Level 1, and this is the one that pairs with a routine sweep.
- You are selling, or buying - Level 2. A flue that has not been scanned has not been inspected for this purpose, whatever the report says. This is the single most common place a Level 1 gets quietly sold as though it settled the question.
- You have had a chimney fire, or think you might have - Level 2 at least. A chimney fire can crack tile and open joints without doing anything visible from the room, and the damage it leaves is exactly what a scan is for.
- You are putting in a new furnace, boiler, water heater, insert or stove - Level 2. Changing the appliance changes what the flue has to carry and how big it should be, and the old flue was sized for the old appliance.
- Smoke or smells coming into the house, or a fire that will not draw - start with an inspection rather than a repair quote. Draft problems are diagnosed, not guessed at.
- Something serious is suspected and the accessible views cannot settle it - Level 3, with the scope and the reason for it in writing first.

Replacing a furnace or boiler: Form F-370
If you are replacing fuel-fired equipment in New Jersey, there is a piece of the code worth knowing about, because it decides who signs for the chimney. N.J.A.C. 5:23-2.20(d) provides that instead of requiring the chimney vent connector to be removed and reinstalled so the chimney or vent can be inspected, the construction official shall accept a Chimney Verification for Replacement of Fuel-Fired Equipment - Form F-370 - signed by the contractor who installed the replacement equipment.
The same provision is explicit about who cannot sign it: verification from homeowners shall not be accepted in lieu of the required inspection. So this is a contractor's signature on the condition of your chimney, given in place of a physical inspection that would otherwise have to happen. That is worth knowing on both sides of the job. If you are having a boiler swapped, ask who is signing the F-370 and what they actually looked at before they did. If the honest answer is that nobody scanned the flue, a Level 2 before the new appliance goes in is the cheapest insurance on the whole project - a new high-efficiency appliance vented into a flue that was wrong for it is a problem that shows up as condensation and deterioration later, long after everyone has been paid.
Both rules are in the state's own text, which we link at the foot of this page: N.J.A.C. 5:23-2 as published by the New Jersey Department of Community Affairs, and the F-370 form itself. The form carries the same warning on its face: it may not be submitted by a homeowner in lieu of the required inspection.
The report, and what we will not put in it
An inspection is worth exactly what its report is worth, so ours is written down: which level was performed, what was accessible and what was not, what the camera saw in each flue, the condition of the crown, cap and flashing, and a plain statement of anything we would want addressed - with the reason, not just the recommendation. If the chimney is sound, the report says that, which is the version worth having on file for a sale.
What it will not contain is a verdict we did not establish. If a flue could not be scanned because it was blocked, the report says the flue was not scanned and why, rather than describing it as satisfactory. If the question needs a Level 3 to answer honestly, we will tell you that instead of guessing from the hearth. And if work is warranted, the quote is separate, free and line-itemed, so the people describing the problem are not the only people you can hear about the solution from.

What a chimney inspection costs in North NJ, by level
An inspection is a priced service with a written report, unlike the quote for any work it leads to. These are whole-job ranges for a single-flue chimney on an ordinary single-family house with a walkable roof, and a chimney carrying a fireplace, a boiler and a water heater runs toward the top of each range or past it.
- Level 1, the annual check of the readily accessible parts: about $150 to $300.
- Level 2, with the camera scan of the flue and the attic, crawl space and basement runs: about $250 to $650.
- Level 3, with permanently attached parts opened to see a suspected hazard and then put back: about $600 to $5,000. The spread is how much has to be opened, and the scope and the reason go in writing before anything is opened.
What affects the cost
| Which level | Level 1, 2 and 3 are genuinely different amounts of work and access. A Level 2 with a full camera scan of every flue is not a Level 1 with an extra item on the invoice. |
|---|---|
| How many flues | A chimney carrying a fireplace, a boiler and a water heater is three separate runs to scan and report on, not one. |
| Access to the system | Attic, crawl space and basement runs are part of a Level 2. A finished basement or a boxed-in chase changes how much of it is reachable, and the report says which parts were. |
| Roof access | A walk-up roof is quick. A steep or three-story stack needs staging and fall protection for the same look at the crown and cap. |
| Opening up, on a Level 3 | A Level 3 involves removing part of the chimney or the building to see what is behind it, plus putting it back. Scope and reason go in writing before anything is opened. |

Common questions
Which inspection level does a house sale need?
Level 2. NFPA 211 calls for it on the sale or transfer of a property, and the part that matters is the video scan of the flue's interior - a Level 1 does not require one, so a flue that has not been scanned has not really been inspected for this purpose no matter how the report reads. If you are buying, ask specifically whether the flue was scanned and ask to see what the camera showed.
Is a chimney inspection required by law in New Jersey?
NFPA 211 is a national standard rather than New Jersey law, and we will not tell you the state compels a homeowner to have an annual sweep. What it is, is the benchmark the trade works to and the framework a serious report is written against. Separately, actual code does come into it around equipment: N.J.A.C. 5:23-2.20(d) covers the chimney verification a contractor signs when fuel-fired equipment is replaced.
Do you scan the flue with a camera?
Yes, as a matter of course. It is what separates a Level 2 from a Level 1 under the standard, and it is the only way to report on the inside of a flue rather than the parts visible from the hearth and the roof. What the camera shows goes in the report.
I had a chimney fire. What now?
Stop using the appliance and book at least a Level 2. A chimney fire can crack tile and open mortar joints while leaving nothing visible from the room, and the whole point of the scan is to find that. Afterwards you will have a written record of the condition, which is the document that matters if an insurer becomes involved.
What is the difference between an inspection and a sweep?
A sweep is cleaning - getting the soot and creosote out. An inspection establishes condition. They pair naturally, because the brush uncovers the tile and the camera reads it, and we scan on every sweep for that reason. But cleaning a flue does not establish that the flue is sound, and any contractor who cleans yours and pronounces it fine has told you something they may not have checked.
Can you inspect a chimney you did not sweep?
Yes. An inspection stands on its own, and there are good reasons to want one from someone who is not also quoting the cleaning - a purchase, a dispute, a second opinion on work someone else recommended. We do both, and we are happy to do only one.
How much does a chimney inspection cost in North NJ?
For a single-flue chimney on an ordinary single-family house with a walkable roof, a Level 1 inspection runs about $150 to $300, a Level 2 with the camera scan about $250 to $650, and a Level 3, which opens part of the chimney or the building and puts it back, about $600 to $5,000 depending on how much has to be opened. More flues or a steep, three-story stack move each toward the top of its range. Precision Windows & Roofing tells you which level your situation calls for before quoting, and the report is in writing.
