Commercial Plumbing Smoke Testing in Far North Dallas
Smelling sewer gas in your business can be an unsettling experience, especially if you cannot determine the cause or pinpoint the source.

Because of the logistical requirements, smoke tests are usually a last resort, BUT they don’t lie! Using safe, non-toxic smoke, we can detect and locate leaks on any commercial property.

We’ll work around your schedule to minimize disruptions to your daily operations and get you back to business fast. Contact us today to tell us about your issue and schedule a service call!
The Earl’s Difference: We’re Always on Your Side
Smoke tests are an effective way to isolate leaks and other vulnerabilities in your plumbing system. That said, they are typically a last-resort option. We’ll make sure to investigate every other possible source of foul odors in your business first to save you time and money on any unnecessary testing methods.
We’ll perform a thorough investigation and listen to your concerns to ensure that we start our diagnostic process in the right place. We’ll begin by checking toilet seals, floor sink and floor drain P-traps, and other common culprits of sewer gas smells before jumping into a smoke test. We work from a foundation of honesty and integrity—which means we start with the simplest, most affordable options and move forward only as necessary.

Answers to Your Frequently Asked Questions
Smoke tests are a valuable tool for finding and pinpointing sewer line breaks and other difficult-to-spot leaks. If you have questions or concerns, we’re here to put your mind at ease.
We don’t have to worry about stopping up sinks or toilets because the water in the P-trap is heavier than the smoke substance. That means it won’t seep through unless there is a bad connection, a dried-out P-trap, or a break in the line.
Possible reasons for sewer gas smell include:
- Bad seals on toilets (likely if you only smell sewer gas in one bathroom)
- Dried out P-traps on floor sinks or floor drains that no longer keep a trapped seal
- Clogged drains
- Blocked air vents
In commercial situations, sewer pipes can easily be punctured by nails, even by hanging pictures. We often see issues in multi-tenant situations where one suite is doing renovations and accidentally damages a shared sewer pipe. Whatever the cause, our team has the expertise and tools to get to the bottom of it.
