Smoke testing

Find hidden sewer leaks without cutting a single wall

We connect a specialized blower to your sewer cleanout and fill the line with non-toxic smoke. Wherever there is a gap, the smoke escapes, and we mark every spot where it shows up.

The test usually takes less than an hour, and the smoke clears by opening a couple of windows. Dye testing and flow monitoring are also available.

Yes. The smoke we use is non-toxic and safe for your family, pets, and property. It has a faint citrus scent and dissipates quickly once the test is complete.

Most residential smoke tests take between 30 and 60 minutes, depending on the size and complexity of your plumbing system.

It’s possible. If smoke enters your home or triggers a smoke alarm, it indicates a leak that needs attention. Opening windows allows the smoke to clear quickly.

Pricing varies based on the type of plumbing system and the size of the property. Contact us for a written quote tailored to your specific situation.

If an issue is found, we’ll show you exactly where the smoke escaped, explain what’s causing the leak, and walk you through your available repair options. There’s no pressure to make a decision during the inspection.

Smoke testing is effective for locating hidden issues such as sewer line leaks, cracked drain pipes, failed joints, broken or missing vent connections, and openings that allow sewer gas to escape. Wherever smoke appears provides a clear visual indicator of the problem— without the need to open walls or floors.
