Can a Drain Camera Be Used to Inspect Chimneys?

Yes. With a compact self-leveling head (≈23 mm), adjustable LEDs, and a centering brush, a drain camera can document creosote build-up, liner cracks, offsets, nests, and moisture trails inside residential chimneys.

What You Can Diagnose

  • Creosote level & texture — flaky vs glossy (Class 3).
  • Liner condition — clay tile cracks/offsets or metal corrosion/dents.
  • Blockage — nests, debris, fallen masonry, damper parts.
  • Moisture trails — staining, rust, efflorescence.

Tools You’ll Need

  • 23 mm self-leveling inspection camera
  • Centering brush / skids sized to the flue
  • DVR recording + adjustable LEDs
  • Optional 512 Hz sonde & locator
  • PPE and roof safety kit

How It Works — Step by Step

  1. Cool down completely.
  2. Enter from firebox up or cap down; attach centering brush.
  3. Begin with low LED brightness; increase as needed.
  4. Advance slowly; pause at each joint to capture stills.
  5. Log distances; use 512 Hz if repairs are planned.
  6. Export video/stills with notes.

Pro Tip: Keep LEDs moderate to avoid wall glare; the centering brush improves framing and protects the lens.

FAQs

 Is a Drain Camera as Good as a Dedicated Chimney Camera?
For most homeowner-level inspections, yes. A drain camera with dimmable LEDs, self-leveling, and a small head will capture clear, actionable footage. Chimney-specific systems often add articulation and tailored centering tools, which are nice to have but not mandatory for basic documentation.
Will Soot or Creosote Damage the Camera?
Not if you work carefully. The bigger risk is scratching the lens or smearing the window until the image goes hazy. Use a centering brush, advance slowly over tile edges, and keep lens wipes handy. Rinse the head gently after use.
Do I Inspect from the Fireplace or the Roof?
Either works. Bottom-up avoids roof work and is safer for many DIYers, but debris on ledges can fall toward you—wear PPE. Top-down is efficient after you’ve confirmed roof safety. Many users do a quick pass from both directions to capture different angles.
What Problems Should Trigger a Call to a Pro?
*Glazed creosote that a brush can’t budge. *Cracked or displaced clay tiles. *Rusted or buckled metal liners. *Persistent water trails or masonry spalling. *Any evidence of a prior chimney fire (melted/bubbled areas, severe cracking).
Do I Need a 512 Hz Locator for Chimney Work?
Usually no. It’s helpful if you’re tracing an odd flue path in a chase or verifying where a thimble emerges, but many chimney inspections don’t require surface locating.
Can I Use the Same Camera for Drains and Chimneys?
Yes—just clean it thoroughly between uses. Consider dedicated skids/brushes for chimneys so you don’t carry gritty debris into plumbing lines.
