Indoor air quality, radon and VOC testing

After a renovation, a ceiling collapse, a new chemical smell, or before you buy: we test the air and tell you plainly whether it’s safe.

Air quality problems are often invisible. A neighbor’s renovation can leave fine dust in your apartment, new furniture and flooring can release VOCs and formaldehyde, and radon can seep into homes from the ground. One visit can cover several tests, and we’ll recommend only the ones that answer your question.

What’s included

  • Radon testing
  • VOC and formaldehyde testing
  • Dust and particle testing after construction or a ceiling collapse
  • Airborne asbestos (PCM/TEM) and lead dust testing
  • Mold air sampling
  • Plain-language reports explaining what the numbers mean and what to do

Radon

Much of New Jersey and parts of New York have elevated radon potential, and radon testing is standard in many home sales and for schools and child care centers.

What it costs

Priced by the tests you need. Combining several tests in one visit costs less than booking them separately.

Frequently asked questions

What should I test after a ceiling collapse?

Usually airborne particles, plus samples of the fallen material for asbestos and dust wipes for lead. All of it can be done in one visit.

How long does a radon test take?

A short-term radon test runs at least 48 hours, then goes to the lab.

Do you test offices, schools and child care centers?

Yes, with documented reports for your records and inspections.

Can you test for VOCs from new furniture or flooring?

Yes: VOC and formaldehyde testing measures what’s off-gassing into the air.
