How Our Process Works

Scheduling and preparation

Call +1 888 890 1313 or book online. We confirm the address, foundation type, and access. We will review the closed house requirements and answer any questions before we arrive.

On-site setup

We place the monitor away from drafts, windows, and high traffic. We log the start time, location, and photos. Instructions are left in plain language to keep conditions stable throughout the test window.

Pickup and reporting

We retrieve the device, review the data, and deliver a clear, shareable report with your measured average, hourly graph, interpretation, and specific next steps. If mitigation is recommended, we explain typical approaches and retesting windows.

Note for full property inspections: Infrared thermal imaging is included with every whole home inspection to help identify moisture and insulation issues that can affect indoor air quality over time.
