10 Questions to Ask Your Chimney Inspector Before They Leave

The 10 Essential Questions

Question 1: What Level of Inspection Did You Perform?

Why it matters: There are three NFPA-defined inspection levels, and you need to know which one you got. A basic Level I inspection is fine for routine maintenance, but if you suspect problems, you need a Level II or III. Knowing the level tells you how thorough the inspection was.

✓ Good answer: "I performed a Level II inspection, which included a complete camera scan of the accessible flue from the firebox to the roof, full exterior and interior visual examination, and testing of draft and combustion safety."
✗ Red flag: "I just looked at it" or "I did a basic inspection" with no mention of camera or specifics. You deserve clarity on what was actually checked.

Question 2: What Is the Exact Condition of My Chimney Liner?

Why it matters: Your liner is the most critical component. You need specifics: What material is it? How old is it? Are there cracks, missing sections, creosote buildup, water damage, or deterioration? Vague answers suggest the inspector didn't look closely enough.

✓ Good answer: "Your chimney has a clay tile liner installed around 1985. I observed three small vertical cracks in the lower section, consistent with normal aging. No missing tiles or major deterioration. The liner is still functional but shows signs of stress from the freeze-thaw cycles we experience here in Chicago."
✗ Red flag: "The liner looks fine" or "I couldn't see much." A professional should give you specific observations, not generalizations.

Question 3: What Level of Creosote Buildup Did You Find?

Why it matters: Creosote is the flammable residue from burning wood. It accumulates over time and is a major fire hazard. Inspectors classify it into three stages (light, moderate, heavy). You need to know which one applies to your chimney and how urgently you need cleaning.

✓ Good answer: "You have Stage 1 creosote—light buildup. Your chimney should be cleaned before next winter. I'd recommend using seasoned hardwood and regular sweeping to prevent it from advancing to Stage 2."
✗ Red flag: No mention of creosote or simply saying "there's some buildup." Creosote assessment is a core part of any wood-burning fireplace inspection.

Question 4: How Is the Crown and Cap Condition?

Why it matters: The crown and cap protect your chimney from water intrusion, which is the enemy of liner longevity. Water damage accelerates deterioration and is expensive to repair. You need to know if either needs attention soon.

✓ Good answer: "Your cap has minor rust but is still functioning. Your crown shows some small cracks that aren't critical yet but should be sealed next year to prevent water from widening them during winter freeze-thaw."
✗ Red flag: "Didn't check the roof" or "Can't see it from the ground." A professional should inspect these from the roof. If they didn't, they skipped a crucial safety check.

Question 5: Did You Check the Flashing?

Why it matters: Flashing is the metal seal where your chimney meets the roof. A leaking flashing is a common source of water damage that gets blamed on the chimney itself. You need to know if it's intact and properly sealed.

✓ Good answer: "I inspected the flashing. It's in good condition with no visible gaps or rust. The caulking is intact and doing its job."
✗ Red flag: "Flashing looks okay from the ground" or no mention of it at all. Proper flashing inspection requires getting on the roof and checking the actual seal.

Question 6: Are There Any Safety Concerns I Should Address Immediately?

Why it matters: This is the life-safety question. Some issues are urgent (blocked chimney, severe damage, structural problems). Others can wait. You need clarity on what's dangerous and what's not.

✓ Good answer: "No immediate safety hazards, but I recommend scheduling a cleaning before winter and a small crown repair within the next year to prevent water damage."
✗ Red flag: Vague statements like "You should probably fix some things" without distinguishing between urgent and routine. A professional prioritizes safety.

Question 7: What Repairs Are Needed, and In What Priority Order?

Why it matters: You may need multiple repairs. Understanding which ones are urgent, which can wait, and which are optional helps you budget and plan. A prioritized list keeps you from making poor financial decisions.

✓ Good answer: "Priority 1: cleaning before winter (required for safety). Priority 2: crown crack sealing next spring (prevents water damage). Priority 3: liner replacement within 5–10 years (you'll see signs when it's truly needed). Estimated costs: $300, $400, $2,500–$3,500."
✗ Red flag: Trying to sell you everything at once or saying "everything needs to be done immediately" when only some items are urgent. Good inspectors prioritize.

Question 8: When Should I Schedule My Next Inspection?

Why it matters: Professional inspectors should recommend a timeline based on your specific situation and Chicago's climate. This helps you stay on top of maintenance and catch problems before they become emergencies.

✓ Good answer: "I recommend annual inspections because you use your fireplace regularly. If you used it less frequently, every two years would be acceptable. Also schedule a cleaning before each winter season."
✗ Red flag: "Come back in two years" without considering your actual fireplace use. Annual inspections are standard for active fireplaces in Chicago.

Question 9: Can You Provide a Written Report With Photos?

Why it matters: A verbal report is easy to forget or misinterpret. A written report with photos documents the inspection, gives you something to reference later, and shows the inspector is confident in their findings. This is standard professional practice.

✓ Good answer: "Yes, I'll email you a detailed report with photos of key findings within 24 hours. It will include recommendations, costs, and timelines."
✗ Red flag: "I don't do written reports" or "I'll send something later and never do." If they won't document their work, that's a red flag. Good inspectors take pride in thorough documentation.

Question 10: Are There Any Code Violations?

Why it matters: Building codes exist for safety. If your chimney violates code (missing cap, improper clearance, no liner, etc.), you need to know, especially if you're selling your home or planning renovations. Code violations can kill a sale or trigger expensive repairs.

✓ Good answer: "Your chimney meets current code requirements. Your cap is secure, clearance from the roof is correct, and the liner is present and functional."
✗ Red flag: No mention of code compliance. A professional should address this as part of a complete inspection.

Signs of a Bad Inspector: What NOT to Accept

Walk Away If Your Inspector:

  • Rushes through the inspection in less than 30 minutes. A thorough inspection takes time.
  • Doesn't use a camera to scan the flue. You need visual confirmation of interior conditions.
  • Provides no written report or refuses to document findings in writing.
  • Can't answer technical questions about liner condition, creosote levels, or inspection levels.
  • Doesn't check the exterior (crown, cap, flashing). Interior-only inspections are incomplete.
  • Pressures you into repairs immediately or quotes vague costs without specifics.
  • Isn't licensed or insured in Illinois. Always verify credentials.
  • Can't explain their methodology or inspection standards. Professional inspectors follow NFPA standards.
