Mold testing and inspection in a home

“It really works! After my kids left the house, I kept our back two bedrooms closed off to save on heating costs. Both rooms are carpeted and after a couple years they took on a very dank smell. After the treatment the smell was completely gone and the air feels clean. I was initially concerned about what the process would do to my house plants (have many) and not even a brown spot occurred. The team was polite and professional and I will definitely have this done again.”

Mold Testing & Inspections

No More Guesswork.

Ascertain if your home or workplace has a mold problem, how bad the problem is, why the problem exists, what its cause(s) are and what can be done. We do this in two ways as part of our mold inspection and testing service.

Specialist mold testing

We have several options when it comes to mold testing. We can discuss which would be most appropriate for your situation if you give us a call or fill out our contact form.

Expert Home Inspection

Our expert technicians will use their suite of specialist diagnostic tools along with their expertise to identify problem areas, likely cause(s) and effective solutions.

Expert Diagnostics

Full property inspection.

Our expert technicians use a suite of professional diagnostic tools, combined with their knowledge, to offer insights as unique as the conditions in your home.

The aim of the inspection is to form a picture of why a mold problem exists and what can be done about it.

  • Behavioral contribution & occupancy patterns
  • Relative humidity mapping room-by-room
  • Moisture content of surfaces & substrates
Our Approach

Testing options. Tailored to your situation.

The type of test you need may differ depending on your circumstances and desired outcomes. Call us for clarification, and we'll help you pick what fits.

Non-viable testing

Air samples are analyzed for both alive (viable) and dead (non-viable) mold spores. The lab records spore count per cubic meter alongside the species present.

Viable testing

We capture mold spores in a mold trap. Captured spores are then cultured on a Petri dish. Any living (viable) spores reproduce, and the species are identified and recorded.

Surface & tape testing

Dust and surface samples are collected from suspected areas and analyzed by an independent laboratory for spore count and genus identification.

Data-Driven Testing

Specialist mold testing.

Testing determines whether mold is present, how severe it is (spore count per m³), which mold strains are present, and how those readings compare against contextual baselines.

Results combine into a single report that gives you fact-based insight into the air quality in the home, the cleanliness of its airspaces, and whether any mold remediation is required.

  • Spore count per cubic meter, per zone
  • Genus & strain identification
  • Contextual comparison against outdoor & baseline samples
  • Plain-language report & clear next steps

When To Test

When testing makes sense.

Not every situation needs a lab-grade test: sometimes a visual inspection and moisture reading tell us everything we need to know. Other situations benefit from the extra data a test provides:

  • Buying or selling a home: a pre-purchase test gives you documented, third-party findings to bring into the transaction, independent of either party's opinion.
  • After remediation: post-treatment clearance testing checks whether spore counts in the treated area have moved back in line with an outdoor baseline.
  • A musty smell with nothing visible: air sampling can help identify growth hidden behind walls, under flooring, or inside HVAC systems when there's an odor but no visible source.
  • Visible growth you want identified: tape or surface sampling can confirm the mold genus present, which helps scope an appropriate remediation plan.

Not sure which of these fits your situation? Call us and we'll talk it through before recommending anything.

Eureka Services

Our mold inspection and testing services in Eureka.

Different questions call for different tests, so here is how we break the work down.

Not every question about a home needs the same answer, so we split inspection and testing into services that match what you are actually trying to find out. Mold Testing covers the lab side of the work: air, tape, and surface samples analyzed by an independent lab to confirm what is present and how much of it there is, rather than a guess based on what a technician can see. Air Quality Testing looks past mold alone at what is actually moving through the air in your home, useful when a smell or a symptom does not point to an obvious source. Attic Mold Inspection, Basement Mold Inspection, and Crawl Space Mold Inspection focus on the three areas of an Eureka home most likely to hide a moisture problem long before it shows up somewhere you can see it, which matters given how much of the older housing stock in town still has vents and foundations from a different era. Bathroom Mold Inspection checks the room that gets the most daily moisture exposure of any in the house, where a fan that is undersized or rarely used can quietly turn into a mold problem over a year or two. Post-Remediation Clearance Testing is the follow-up step after treatment, whether it was ours or someone else's, confirming spore counts have come back in line with an outdoor baseline before anyone calls a job finished. Whichever service fits your situation, the same independent lab, the same NORMI Certified Sanitizing Professional oversight, and the same plain-language reporting apply across all of them.

Frequently Asked

Questions about mold testing and inspections.

An inspection is a visual and moisture-based walkthrough of the property. Testing adds a lab-analyzed air, tape, or surface sample on top of that, giving you a documented spore count instead of a visual estimate alone.

Standard results typically come back in three to five business days. Rush turnaround can sometimes be arranged if you let us know when you book.

If mold is visible, we can often move straight to treatment. Testing is most useful when there is a smell but nothing visible, before a real estate transaction, or when you want a documented baseline before and after work.

Yes. If our inspection does not turn up an active mold problem, we will tell you rather than recommend treatment you do not need.
