Separate cleaning from inspection, choose the scope that fits the system and recent events, and require a written safe-use record before the next fire.
A chimney sweep removes deposits. An inspection evaluates condition and safe use. They may happen during the same visit, but they answer different questions. Before booking, identify every fireplace, stove, furnace, boiler, or water heater connected to the chimney and ask what inspection level and written record the visit includes.
Start with appliance and use history
Record each fuel-burning appliance, fuel, last use, last cleaning and inspection, repairs, known chimney fire, water entry, animal entry, appliance replacement, property sale, earthquake, storm, or long period out of service. Note smoke entering a room, unusual odors, soot, staining, falling masonry, poor draft, or a carbon-monoxide alarm. Do not light a test fire to reproduce a warning sign.
Keep the fireplace or appliance off after a chimney fire, visible damage, smoke spillage, a fuel-gas odor, or a carbon-monoxide alarm until qualified evaluation says it is safe. For an active alarm, smoke, or gas odor, get outside and use emergency or utility help from a safe location.
Ask which inspection level fits the event
A basic visual inspection may fit a regularly serviced system with no change in use or condition. A more detailed inspection may be appropriate after a property transfer, change in appliance or fuel, relining, operating problem, chimney fire, or event that could have caused damage. The contractor should explain the level, accessible areas, camera use, limitations, and what would trigger invasive investigation.
Do not accept “inspection included” without a scope. Ask whether the visit covers the firebox or appliance connection, smoke chamber, damper, flue and liner, cap and crown, exterior masonry, flashing, accessible attic or crawlspace portions, connector pipes, clearances visible without demolition, and each separate flue.
The three inspection levels at a glance
The level you need depends on whether the system has changed since it was last inspected. NFPA 211 defines the three inspection levels; the CSIA publishes standard operating procedures as professional guidance for sweeps and inspectors, and local codes or transaction requirements can differ. The matrix below separates what each level covers, when it is typically applied, and how much access it grants. It does not include removing any building component except under Level 3, where special tools may be needed to reach a concealed hazard.
| Level | When it applies | Covers | Adds beyond the previous level |
|---|---|---|---|
| Level 1 | System under continued service, same appliance and fuel, no change in condition | Readily accessible exterior, interior, and appliance connections | None — the baseline visual check; verifies soundness and freedom from obstructions and combustible deposits |
| Level 2 | CSIA recommends it after a property sale/transfer, fuel-type change, flue relining, a new or dissimilar appliance, an operating malfunction, or an external event (fire, seismic, weather) | Everything in Level 1 | Accessible attics, crawl spaces, and basements plus video scanning of the flue liner; no component removal |
| Level 3 | When a Level 1 or Level 2 finding points to a hidden hazard that cannot be evaluated without special tools to reach concealed areas | Everything in Level 1 and Level 2 | Removal of components such as the chimney crown or an interior wall, only as necessary to access the suspected area |
CSIA guidance recommends Level 2 after a property transfer, change of fuel type or appliance, flue relining, an operating malfunction, or an event such as a chimney fire, earthquake, or severe weather that could have damaged the system. It is professional guidance, not a universal legal, lender, or insurance requirement. Local rules and transaction terms can set a different scope, so confirm what applies before the visit. If the same appliance runs on the same fuel with no known change, CSIA guidance treats Level 1 as the baseline scope.
Connected flues and appliances matter
CSIA Level 2 guidance says that when this deeper scope is recommended, all flues and their connected appliances should be included in the inspection. Ask the inspector to identify the appliances and flues included in the scope. A report that identifies only one appliance should state whether other connected appliances or flues were outside the inspection.
If an appliance was replaced or a fuel type changed, tell the inspector before the visit. Those changes are among the conditions for which CSIA recommends Level 2. The report should identify the areas inspected, any access limits, and the condition observed in each flue included in the scope.
Prepare the house without creating a hazard
Follow the company’s cooling-time instructions and do not use the appliance beforehand. Clear ordinary furnishings and fragile items from the work area, contain pets, and provide safe access to records and controls. Leave roof access, ladders, flue entry, heavy appliances, and removal of service panels to the professional. Tell the inspector about alarms, health sensitivities, loose masonry, or prior water damage before work starts.
Require findings you can act on
A useful report identifies the system and flue, areas observed, deposits, obstructions, liner condition, masonry and moisture findings, connector and appliance concerns, access limitations, photographs or video, and whether use should stop. It separates cleaning from repair and distinguishes an observed defect from a condition that could not be evaluated.
Before using the system again after a concern or repair, keep a written record stating the level performed, the appliances and flues covered, and the access limits. A Level 2 includes video scanning or similar inspection of the chimney interior; if that could not be completed, the report should say so. If the report cannot answer what level was performed and what could not be seen, ask for clarification before relying on it.
Understand the limits too: Level 1 and Level 2 do not call for removing permanently attached building or chimney components. Level 3 reaches concealed areas only when a Level 1 or Level 2 finding suggests a hidden hazard. A clear Level 1 record describes the areas observed; it does not establish the condition of concealed areas. Keep the record with the system's service documents so the next qualified professional can see what work and access were included.

Compare the scope before booking
Ask each company to name the inspection level, the appliances and flues included, the accessible areas it expects to inspect, and whether cleaning is a separate service. For a Level 2, ask how the interior scan will be documented and how inaccessible areas will be recorded. This makes proposals comparable without assuming that every property needs the same level.
Provide the same appliance history, changes, and event notes to each company. Ask what the report will identify, which areas were inaccessible, and whether a finding calls for further evaluation. Do not treat a property transfer, insurance question, or repair proposal as proof that one particular level is universally required; confirm the applicable local and contractual requirements.
For each recommendation, ask what evidence supports it, whether the repair is needed before use, which trade or permit applies, and how completion will be verified. Get another qualified opinion before expensive relining or reconstruction when the evidence or scope is unclear. Do not rely on a door-to-door claim or same-day pressure to approve major work.
Plan the inspection cost by level
HomeGuide's February 2026 national planning guide lists $100 to $250 for a Level 1 inspection, $250 to $600 for Level 2, and $900 to $5,000 for Level 3. The Level 3 range is wide because access may require selective removal of building or chimney components. Those figures are not a local quote, and a sweep, roof access, multiple flues, travel, permits, or repair work may be priced separately.
Save money by sending every bidder the same appliance list and event history, then comparing the same inspection level and report deliverables. Ask whether cleaning is included, what triggers extra work, and whether a fee is credited toward later service. Do not choose Level 1 just because it costs less when the system history points to Level 2, and do not approve destructive Level 3 access without a documented finding that explains why concealed access is needed.
Close the loop after service
Save the report, images, invoice, removed material notes, repair scope, permits, warranties, and the next inspection recommendation. Test smoke and carbon-monoxide alarms according to their instructions and restore the room only after work is complete. Add the chimney to the seasonal home-care calendar, but let the appliance instructions, system condition, use, and local requirements set the actual service plan.
The best visit leaves a plain answer to three questions: what was observed, what must change before the next fire, and what could not be seen. If the paperwork cannot answer those, the inspection is not finished.

Frequently Asked Questions
What should a chimney inspection include?
A useful chimney visit identifies the appliances and flues, visible condition, access limits, safe-use decision, and evidence behind each repair recommendation.
What is the difference between a Level 1 and a Level 2 chimney inspection?
A Level 1 covers readily accessible exterior, interior and appliance connections when use has not changed. A Level 2 adds accessible attics, crawl spaces and basements plus video scanning of flue liners. CSIA recommends Level 2 after a property transfer, fuel change, relining, a new or dissimilar appliance, or an event that may have caused damage; local requirements can differ.
When is a Level 3 chimney inspection needed?
When a Level 1 or Level 2 inspection points to a hidden hazard that cannot be evaluated without special tools to reach concealed areas of the chimney or flue. It removes components such as the chimney crown or interior wall only as necessary to access those areas.
Does a chimney sweep count as an inspection?
No. Sweeping removes creosote and obstructions, while an inspection evaluates structure and safe use. They can happen during one visit but answer different questions, so ask whether the visit includes a written record of the level performed.
