Every chimney inspection is not the same visit. The NFPA 211 standard, which chimney professionals follow, calls for chimneys, fireplaces and vents to be inspected once a year. It also defines three levels of inspection, and each one goes deeper than the last. The right level depends on what has happened to your system since it was last checked. This guide explains what each level covers, when you need it, what you receive afterward and how to get your Staten Island home ready for the visit. Our certified technicians will tell you which level fits your situation and why, so you are not paying for more inspection than you need or settling for less than the situation calls for.
Level 1: The Annual Inspection
A Level 1 inspection is the standard yearly check for a chimney that has been working normally and has not changed. It is the inspection most homeowners need most of the time, and it is often paired with a chimney sweep.
The technician examines the parts of the system that can be reached without special tools or opening anything up. The goal is to confirm the chimney is sound, free of blockages and free of combustible buildup.
- Readily accessible parts of the chimney exterior and interior
- The firebox, damper and smoke chamber where they can be seen
- Creosote and soot buildup in the flue
- Obstructions such as nests, leaves or debris
- Basic connections for appliances vented into the chimney
Level 2: When Something Has Changed
Under NFPA 211, a Level 2 inspection is called for when the system changes or the home is sold. Changes include installing a new appliance, such as a wood stove insert or a new boiler, or switching fuels. Because it looks further into the system, Level 2 almost always includes a video scan of the full length of the flue.
A fuel switch is a common reason for a Level 2 inspection in New York City. When a building converts its boiler from oil to gas, the chimney has to be evaluated as part of the work. A new liner is often needed, because gas exhaust produces acidic condensate that can corrode a masonry flue. If your inspection shows the existing flue is not suited to the new appliance, we can explain your chimney liner installation options.
We also recommend a closer look after any event that may have damaged the chimney, such as a chimney fire or a severe storm. Cracked flue tiles, loose bricks and a displaced chimney cap or chase cover are not always visible from the ground or the fireplace opening.
- Everything covered in a Level 1 inspection
- A video scan of the interior of the flue
- Accessible areas of attics, crawl spaces and basements the chimney passes through
- Clearances to combustible materials where they can be reached
- The exterior from the roof, including the crown, flashing, cap and chase cover
Level 3: Reaching Hidden Hazards
A Level 3 inspection is the most involved. It is used when a hazard is suspected but cannot be confirmed without opening part of the chimney or the building. This could mean removing a section of wall, a chimney chase panel or part of the masonry to see what is behind it.
Level 3 is not a routine step. It is usually recommended only after a Level 1 or Level 2 inspection points to a serious concern that cannot be fully evaluated any other way. We will explain the reason, what needs to be opened and what is involved before any work begins. If repairs are needed, the findings guide whether the right fix is chimney repair, fireplace and damper repair or a partial or full chimney rebuilding.
What You Get After the Inspection
You should understand your chimney's condition without having to take anyone's word for it. After the inspection, you receive documentation of what the technician found.
If everything checks out, the report says so. If there are problems, it lays out the options and leaves the decision to you.
- Photos of the areas that were inspected and any problems found
- Video footage of the flue interior for Level 2 inspections
- A written report describing the condition of the system
- Plain explanations of what needs attention now and what can wait
- Recommendations such as a sweep, waterproofing, a new cap or liner work
How to Prepare for the Visit
A little preparation helps the visit go smoothly and lets the technician see everything that matters.
- Stop using the fireplace or stove at least a day ahead so the system is cool
- Clear furniture, rugs and decorations from around the hearth
- Make sure the technician can reach the attic, basement or boiler room if the chimney runs through them
- Put pets in a separate room
- Write down anything you have noticed, such as smoke odors, drafts, water stains or falling debris
- Have records of recent work or appliance changes on hand
Inspections
Three levels of chimney inspection
The NFPA 211 standard calls for a yearly inspection. Which level you need depends on what has changed since the last one.
-
Level 1
Annual check
For a chimney and appliance that have not changed and will be used the same way: the readily accessible parts of the chimney, the flue and the connection, checked for soundness, blockages and deposits.
-
Level 2
Camera inspection
When something changed — a new stove, insert or boiler, a fuel switch such as oil to gas, the sale of the home, or a chimney fire, storm or quake. Adds a video scan of the whole flue and the accessible attic, roof and crawl spaces.
-
Level 3
Concealed areas
Only when a Level 1 or 2 points to a hidden hazard that cannot be checked any other way: parts of the chimney or building are opened to reach it.
FAQ
Common questions
How often should my chimney be inspected?
NFPA 211 calls for chimneys, fireplaces and vents to be inspected once a year. This applies even if you rarely use the fireplace, since animals, weather and moisture can cause problems without any fires being lit.
Which inspection level do I need when buying or selling a home?
A Level 2 inspection. NFPA 211 lists the sale of a home as a reason for Level 2, because the buyer needs a fuller picture of the system than a routine check provides.
Does switching my boiler from oil to gas require an inspection?
Yes. A fuel switch is a system change that calls for a Level 2 inspection. In New York City, the chimney has to be evaluated when a boiler converts from oil to gas, and a new liner is often needed because gas exhaust creates acidic condensate that can corrode masonry.
Is a chimney inspection the same as a chimney sweep?
No. A sweep removes soot and creosote. An inspection evaluates the condition of the system. They are often done during the same visit, and a sweep may be needed so the technician can see the flue clearly.
Will a Level 3 inspection damage my home?
A Level 3 inspection does involve removing part of the chimney or building to reach a suspected hazard. We explain what needs to be opened and why before starting, and it is recommended only when other inspection levels cannot answer the question.
When is the best time to schedule an inspection?
Before you start using your fireplace or heating system for the season. New York City's heat season runs from October 1 through May 31, so late summer or early fall gives you time to handle any repairs before you need heat.
