Mold Inspection
A mold inspection is someone walking the building with moisture meters and, usually, a thermal camera, to find where water is getting in and what it has affected. It answers 'is there a moisture problem here, and how far does it reach' — which is the question that has to be answered before anyone can price removal.

Who this is for
- You can smell something musty but cannot see anything
- You had a leak, a flood or an ice dam and want to know what it reached
- You found something growing and need to know how far it goes
- You are buying and want the property looked at before the contingency expires
- A tenant has reported a problem and you need it documented
- Your home inspector flagged moisture and recommended a specialist
What the service includes
A visual survey
Every accessible area, with attention to the places water collects: below grade, under sinks, around windows, at the roof line, and anywhere the building has been altered.
Moisture readings
Pin and pinless meters on suspect materials, compared against dry areas of the same construction. This is what distinguishes an old stain from something still wet.
Thermal imaging
A camera showing temperature differences across surfaces. It does not see mold — it shows cool patches that often mean wet material behind the finish, which then gets confirmed with a meter.
A written report
Findings, photographs, the moisture readings, and a recommendation. This is the document you use to get comparable remediation quotes, or to negotiate a purchase.
How this differs from the others
Inspection, testing, remediation and independent clearance are four different jobs. Buying the wrong one is the most common and most expensive mistake in this category.
Inspection vs testing
An inspection finds the moisture and the extent. Testing sends samples to a laboratory to identify what is growing. Most situations are settled by the inspection; testing earns its cost when you need documentation, or when something is clearly wrong and nothing visible explains it.
About mold testing →Inspection vs remediation
A remediation company removes material and dries the structure. Some also inspect. That is legal and often competent, but the firm is then estimating work it will be paid to perform — worth knowing when you read the findings.
About remediation →Inspection vs clearance
Clearance testing happens after remediation, to confirm the work met its scope. It should be done by someone with no involvement in the removal.
About clearance testing →Inspection vs a home inspection
A general home inspection covers the whole property at a survey level and will flag visible moisture. It is not a mold assessment, and most home inspectors say so in their own reports.
Buying a home →What to expect, step by step
- 1
Intake
You describe what you have seen, smelled or repaired. A good inspector asks about the building's history before arriving.
- 2
Walkthrough
One to three hours for a typical single-family house, longer if there are multiple areas or the building is large.
- 3
Moisture mapping
Readings recorded against locations, so the extent can be drawn rather than estimated.
- 4
Optional sampling
If sampling is warranted, it is agreed at this point rather than assumed — and priced separately.
- 5
Report
Usually within two to five business days. Ask up front what the report will contain and whether photographs are included.
What it costs
| Service | Typical range | What drives it |
|---|---|---|
| Visual inspection, single-family home | $300 – $600 | Square footage, number of areas of concern, travel. |
| Inspection with thermal imaging | $400 – $800 | Equipment and the time to interpret it properly. |
| Large or commercial building | Quote required | Scoped per building. Expect a walkthrough before a price. |
| Report only, no sampling | Usually included | Confirm this — some firms charge separately for the written report. |
General US ranges for planning purposes, not quotes and not local data. Price depends on the size of the building, how much has to be opened up, and what the market charges where you live. Compare at least two written scopes before deciding.
Start with the property
An address check is free and takes a few seconds. It will not tell you whether there is mold in the building, but it will tell you which conditions are stacked against it — which is useful context to bring to whoever you hire.
A data-based estimate — not an inspection, mold test, or medical diagnosis. How this works · How we handle your address
How to choose between companies
- Ask whether they also perform remediation, and how they handle that when they find something.
- Ask what the written report includes, and ask to see a sample with the address redacted.
- Ask which moisture instruments they use and whether readings are recorded by location.
- Check licensing requirements in your state — some require a licence to assess, some do not.
- Ask what happens if they find nothing. A firm that only makes money when something is wrong has an awkward incentive.
