Vapor intrusion happens when harmful gases move from contaminated soil or water into the air inside a building.

They usually come from spills or leaks—like from gas stations, dry cleaners, or old tanks—and move through the ground.

Yes. Some vapors, like PCE, TCE, or gasoline compounds, can be harmful to people if they build up in indoor air.

The only way to know for sure is to test the soil gas or indoor air. We install vapor points or use small air cans to check.

You may need testing if you're near a contaminated site, if your site has VOCs, or if NJDEP requires a vapor evaluation.

It’s a process that reviews laboratory test results, building use, and soil data to see if vapors might enter the air inside.

If the levels are too high, we help install a system—like a fan or vent—to keep the vapors from entering the building.

Yes. If vapor risks aren’t handled, it can hold up your deal. Testing and a plan help keep things on track.

It depends on the deal. But either way, we’ll give you the data, explain the risks, and help with the next steps.

We’re fast, experienced, and NJDEP-compliant. We help you test, fix, and move forward—without confusion or delay.
