Indoor Air Quality

Mold Testing

Even though there are currently no standards to measure mold levels, mold can be a serious health risk for some people. Inhaling mold spores may cause an allergic reaction in sensitive individuals. Molds can also cause asthma attacks in asthmatic people. Today, with tighter building construction techniques being used, buildings and homes can become a breeding ground for mold amplification. Mold will likely grow and become a problem in an indoor environment where there is excessive moisture, such as water damage, leaks or high humidity.

Our mold services include:

  • Visual Assessments

  • Surface & Swab Sampling

  • Air Sampling

  • Clearance Testing

  • Pre & Post-Remediation Testing

  • Protocol Development

  • Moisture Content Assessments

  • Certified Inspector

Indoor Air Quality Testing

Indoor air quality can be five times worse than outdoor air quality. Tighter construction techniques limit air exchange rates causing pollutants to accumulate. There are also many items in any structure that can release pollutants thereby compounding the problem. Poor indoor air quality can cause a wide variety of health symptoms.

Our air quality testing looks for:

  • Mold (Council-Certified Residential Mold Inspector)

  • Toxins

  • Carbon Monoxide

  • Particulates

  • Carbon Dioxide

  • Asbestos

  • VOCs

  • Radon

  • Humidity & Temperature

  • Bacteria

Radon Testing

Radon, a known carcinogen, is a colorless, odorless, invisible gas that enters your house through cracks and joints in your foundation. Radon is caused by the natural decay of radioactive elements in the soil and can exist in either an old home or a brand new home.

ESG uses a continuous radon monitor that produces fast results in as little as 48 hours. Whether you have a basement, crawlspace or on a slab, you should have your house tested to determine the concentrations of radon.

ESG conducts radon testing for large buildings, schools and multifamily buildings following MALB & MAMF AARST-ANSI protocols.


Asbestos Inspections

Asbestos is a naturally occurring mineral that is mined from the earth. Asbestos has been used in many building materials due to its excellent physical properties. However, asbestos is a known carcinogen that can cause ailments such as, lung cancer, asbestosis and mesothelioma. Older homes have been known to have floor tiles, pipe insulation, vermiculite insulation and other materials that may contain asbestos.

If left alone, asbestos does not cause any issues. However, if damaged, fibers can be released into the breathing zone and inhaled.

ESG provides asbestos testing services using State certified inspectors.
