Chimney Smoke Test Services

What is a Chimney Smoke Test?

A smoke test introduces non-toxic smoke into your chimney system while the top is sealed. Any smoke escaping through cracks, gaps, or breaches in the flue becomes visible, revealing problems that cannot be detected through visual inspection alone. This test is essential for verifying flue integrity and identifying potential carbon monoxide pathways.

When Smoke Testing is Needed

Several situations call for smoke testing to verify chimney safety and integrity.

• Real estate transactions involving fireplaces
• After chimney fires to assess damage
• When carbon monoxide leaks are suspected
• Before installing new heating appliances
• When visible damage suggests potential breaches
• As part of comprehensive Level 2 inspections

The Smoke Test Process

We seal the top of the chimney and introduce smoke from the bottom using professional smoke-generating equipment. The smoke fills the flue and will escape through any cracks, gaps, or openings in the liner. We observe the chimney from inside and outside the home to identify all breach points. The non-toxic smoke dissipates quickly after testing.

Interpreting Results

Smoke escaping at specific points indicates breaches that allow combustion gases to enter wall cavities or living spaces. We document all findings and provide recommendations for repair. Common issues revealed include cracked flue tiles, deteriorated mortar joints, gaps at cleanout doors, and breaches in prefabricated chimney systems.
