Chimney inspection: the three levels, what they cost, and when you need each
A chimney inspection checks the chimney, flue and connections for cracks, creosote buildup and damage. A Level 1 inspection, the yearly one, costs $100 to $250 with a basic cleaning and takes 45 to 60 minutes, according to HomeGuide; Level 2 adds a video inspection and costs $250 to $600; Level 3, which opens up concealed parts of the structure, costs $900 to $5,000. The NFPA says to have chimneys cleaned and inspected every year by a qualified professional.
The three inspection levels
| Level | What it covers | When | HomeGuide | Fixr |
|---|---|---|---|---|
| Level 1 | Visual check of the accessible interior and exterior, the flue and its connections | Every year, for a chimney in regular use | $100 to $250 | $85 to $950 |
| Level 2 | Level 1 plus a video inspection and the roof, attic, crawl space or basement as needed | Buying a home, damage found, after a storm or small fire, or a long idle period | $250 to $600 | $150 to $1,000 |
| Level 3 | Removes parts of the structure to see concealed areas | Serious damage suspected that a camera cannot assess | $900 to $5,000 | $500 to $5,000 |
What is a level 1 chimney inspection?
A Level 1 inspection is a visual check of the accessible interior and exterior to verify the flue and its connections are safe. HomeGuide says inspectors look for cracks, creosote buildup and signs of wear or damage, that it takes 45 to 60 minutes including a basic cleaning, and that it is for well-maintained chimneys in regular use. Fixr adds that a Level 1 inspection should be done yearly for a chimney you use regularly, and is often done at the same time as the cleaning.
What is a level 2 chimney inspection?
A Level 2 inspection includes everything in Level 1 plus a video inspection of the internal parts and hard-to-reach areas, and the specialist examines the roof, crawl space or basement as needed. HomeGuide says it takes 1 to 2 hours and recommends it when buying a home with a chimney, when a chimney has not been used for a long time, or when you see signs of damage. Fixr says it is warranted when a Level 1 inspection shows wear or damage, after a significant storm, or after a minor fire.
What is a level 3 chimney inspection?
Level 3 is the invasive one. Fixr describes it as an inspection where some parts of the main structure are removed so the inspector can see concealed areas, done only when a sweep suspects serious structural problems, after a significant fire, or when a Level 2 inspection finds damage the camera cannot fully assess. HomeGuide calls it rare and says its $900 to $5,000 price includes minor repairs as part of the analysis.
How often should a chimney be inspected?
Once a year. The NFPA's heating safety tip sheet says to have heating equipment and chimneys cleaned and inspected every year by a qualified professional, and Portland Fire & Rescue says to have the chimney inspected before every heating season. Timing matters: in fire department records for 2020 to 2024, 57.4% of chimney fires happened in December, January and February, so an inspection in early fall covers the riskiest months.
Chimney inspection cost
Fixr puts the national average at $400 and prices inspections by the number of flues as well as the level:
| Flues | Level 1 | Level 2 | Level 3 |
|---|---|---|---|
| 1 flue | $85 to $250 | $150 to $400 | $500 to $5,000 |
| 2 flues | $150 to $550 | $300 to $600 | $500 to $5,000 |
| 3 flues | $450 to $750 | $500 to $800 | $500 to $5,000 |
| 4 flues | $550 to $950 | $600 to $1,000 | $500 to $5,000 |
Fixr says an inspection with cleaning averages around $175 for a Level 1 inspection of one flue and around $450 for a Level 2 inspection of two flues. Sweep-only prices are in the chimney sweep cost guide.
After a chimney fire
The Chimney Safety Institute of America says a fire department's job at a chimney fire is to contain and put out the fire, not to clean, inspect or evaluate the chimney afterward, so that needs a chimney professional. The evaluation it describes includes an internal video inspection, with a camera lowered down the chimney or run up from below to check the flue tiles and other parts. CSIA says most chimney fire damage is considered a covered loss under homeowners insurance, and advises asking the sweep to document the damage with photos before the chimney is swept. If the inspection finds damage, see chimney repair costs.
