Indoor Air Quality Services
The building-science side of the air you breathe indoors.
Short answer
Indoor air-quality (IAQ) services evaluate the building conditions that affect indoor air — humidity, ventilation, moisture, and mold-related concerns. Sterling focuses on the building-science side: measuring humidity and moisture, evaluating HVAC-related conditions, and sampling when useful. IAQ findings are informational and are not a medical or health diagnosis.
Also called: IAQ testing, indoor air quality testing, home air quality test

A calm, methodical process.
Step 1: Understand
We review the space, its systems, and your concerns.
Step 2: Measure
We assess humidity, moisture, and HVAC-related conditions.
Step 3: Sample (if useful)
We sample only when it will meaningfully inform the picture.
Step 4: Explain
You get documented, plain-language findings and next steps.
Thermal imaging reveals hidden moisture.
Drag the slider — infrared exposes the cold signature of moisture behind a wall that looks perfectly normal. It's the difference between guessing and knowing.
Methods & equipment
- Hygrometer (humidity)
- Moisture meters
- Infrared thermal camera
- Sampling when warranted
What you receive
- Written IAQ findings
- Humidity and moisture readings
- Recommended next steps
Typical timing
IAQ evaluations are performed on-site; any laboratory analysis depends on the lab.
Pricing
$700 flat
$700 flat for properties up to 2,500 sq ft, then $50 per additional 500 sq ft. That is everything in the Basic inspection plus one indoor sample, one outdoor control, and the Laboratory Results Interpretation, which is $50 under buying the two samples at list price.
Indoor Air Quality Services — questions
No. Our IAQ work is building-focused and informational. We do not diagnose health conditions or make medical claims. For health questions, consult a medical professional.
