Mold Testing & Sampling
Laboratory sampling — used when it will actually answer a question.
Short answer
Mold testing collects air or surface samples that a laboratory analyzes to identify and quantify mold. Sampling is one tool within a broader assessment: it supports the investigation but does not, by itself, locate the moisture source. Sterling recommends sampling when it answers a real question — not by default.

A calm, methodical process.
- 1
Define the question
We decide what a sample would actually tell us before collecting one.
- 2
Collect
We take representative air and/or surface samples with proper controls and baselines.
- 3
Chain of custody
Samples are documented and submitted to an accredited laboratory.
- 4
Interpret
We explain the results in plain language, including their limitations.
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
- Spore-trap air cassettes
- Tape-lift / swab surface sampling
- Outdoor baseline comparison
- Accredited-laboratory analysis
What you receive
- Laboratory report
- Indoor-vs-outdoor comparison
- Written interpretation and recommended next steps
Typical timing
Samples are collected on-site; laboratory turnaround depends on the laboratory and the analysis requested. We share and explain results as soon as they are available.
Pricing
Sampling cost depends on the number and type of samples and the lab analysis selected. We recommend only the samples that serve your goal. Request an estimate.

Mold Testing & Sampling — questions
Often not. Visible growth usually confirms a mold problem that needs to be corrected regardless of a number. Sampling can still help when you need to scope the extent, document a baseline, or verify clearance.
