Residential and Commercial indoor air quality experts

Homeowners usually don’t know where their energy losses are. That’s where having a Blower Door Test and/or Thermal Imaging can help in locating the anomalies that lie deep within the structure.

We help find damaged, non existing or poor insulation in the walls and attic space, poorly performing windows and doors such as the air tightness that surrounds them.

Our tests and processes performed reveal air infiltration (air getting into the house) and Exfiltration (air escaping from the house).
