Indoor air quality testing.

You breathe indoor air most of the day. Testing identifies what is circulating through the property, from mold spores and particulates to humidity problems that cause them.

Air quality

The symptom is in the air, the cause is in the building.

Indoor air problems almost always trace back to moisture, ventilation or a mechanical system doing its job badly. We sample the air and then look for the building condition behind the result.

When testing makes sense.

Three situations where air sampling earns its cost.

Symptoms at home

Congestion or irritation that eases when you are away from the property points at the indoor environment.

After water damage

A leak that was dried on the surface can leave growth inside the wall cavity for years.

What does indoor air quality testing cover?

Air sampling for mold spores and particulates, plus humidity, ventilation and HVAC observations that explain the result.

Typically a few business days after the samples reach the accredited laboratory. We review the report with you once it arrives.

Mold testing is one part of it. Air quality testing also looks at humidity, ventilation and the mechanical systems moving air through the property.
