Chimney inspections in San Antonio
An inspection answers one question: is this chimney safe to use the way you use it? The national fire code for chimneys sets three levels, and which one you need depends on why you are asking.

The three levels
NFPA 211's Chapter 15 sets three levels. Level I covers the parts of the chimney and fireplace you can readily reach. Level II adds accessible attics and crawl spaces and scans the flue liner with image scanning equipment. Level III opens concealed areas by removing parts of the chimney or building, and is used only when Level I or II cannot answer the question.
| Level | When | What it covers |
|---|---|---|
| Level I | Every year, and with a routine sweep | Readily accessible parts of the chimney and fireplace, and that the flue is clear |
| Level II | Home sale or relining; a new appliance; after a chimney fire or storm | Everything in Level I plus accessible attics and crawl spaces, and an image scan of the flue liner |
| Level III | Only when Level I or II finds a problem it can't fully see | Concealed areas, reached by removing parts of the chimney or building |
Summarized from NFPA 211, Chapter 15.
When NFPA 211 calls for a Level II
NFPA 211 calls for a Level II inspection on sale or transfer of the property and before a flue is relined. It also calls for one when an appliance is added or removed or swapped for a different type, and after a chimney fire or any other event likely to have damaged the chimney.
The home sale is the one most San Antonio buyers miss. A general home inspection usually looks at the chimney from the outside and the firebox from the front. The flue liner, where the cracks that matter usually are, takes a camera.

What to ask for
- Which level is this, in writing?
- Photos or video of the flue, and a written report of what was found.
- For a Level II on a sale: a report you can hand to the seller or your agent before the option period ends.
- If a repair is recommended, the price separately, so you can get a second quote.
Questions San Antonio homeowners ask
How often do I need a chimney inspection?
NFPA 211 is the national fire code for chimneys. It says chimneys and vents shall be inspected at least once a year for soundness and freedom from deposits. Cleaning and repairs follow if needed.
Is a Level 2 chimney inspection required to sell a house in Texas?
NFPA 211 calls for one on sale or transfer of a property, but no Texas law we know of makes it a condition of closing. Buyers ask for it because a general home inspection rarely includes a camera look down the flue.
Can a home inspector inspect a chimney?
A general home inspector will look at what is visible. A camera scan of the flue liner is usually a separate service from a chimney company.
