Mold Inspection

Certified, independent mold inspection across Orange County

We find the mold and the moisture behind it, sample what the property needs, and deliver an objective, accredited-lab report. We inspect and test only, never remediate. Same-day inspections often available.

The inspection

What a mold inspection actually covers

A mold inspection is more than spotting a stain on the wall. We assess the whole property, find the moisture that is feeding the mold, and document what is really there with accredited-lab testing, so you get facts you can act on rather than a guess. Because we only inspect and test and never remediate, nothing in the report is shaped by a cleanup we are trying to sell.

What we look for

We find the mold, and the water behind it

Mold is a symptom; moisture is the cause. We walk the property for visible and hidden growth, then use moisture meters and thermal imaging to locate the water intrusion feeding it, because if the source is not found and fixed the mold returns after any cleanup. Where it is warranted, we collect air and surface samples so an accredited lab can identify the mold type and how much is present.

How your inspection works, in three steps

1

Schedule Your Inspection

Tell us what you are seeing or dealing with, and we book you the soonest appointment, often same-day, at a clear, itemized price.

2

On-Site Inspection & Sampling

We assess the property, locate the moisture source with meters and thermal imaging, and collect the air or surface samples the situation calls for.

Lab Report & Next Steps

An accredited lab analyzes the samples and you get a written report with the findings and clear next steps you can act on.

The report

Scientific, straightforward reports you can act on

Every finding is backed by accredited-lab analysis, not a handheld reading on the spot. If you have already been quoted for mold remediation, that report is what you measure the quote against. Your written report lays out where the moisture and mold were found, the likely source, the lab results and what they mean, and clear next steps. It is documentation you can hand to a remediation contractor, a buyer or seller, an insurer, or an attorney and rely on.

Why GPMI

Independent, so the findings stay honest

We inspect and test only, and never sell remediation, so what our report says is driven by the property, not by a cleanup we are trying to sell you. That independence, backed by accredited-lab analysis and our certifications, is why homeowners, buyers, attorneys, physicians, and insurers rely on our findings.

Questions

Mold inspection FAQ

Straight answers from a certified, independent team.

What happens during a mold inspection?
We start with your history, walk the property for visible growth and for the conditions that create it, then use moisture meters and thermal imaging to find dampness behind walls, ceilings, and floors. Where sampling will actually answer a question, we collect air or surface samples and send them to an accredited laboratory. You receive a written report with what we found, where the water is coming from, what the laboratory results mean, and what to do next.
I can already see the mold. Do I still need an inspection?
Usually yes, and not for the reason you would expect. Seeing mold tells you there is a problem. It does not tell you how far it extends behind the surface, what is feeding it, whether the air in the rest of the house is affected, or what scope of work a contractor should actually be quoting. That is what a remediation contractor, an insurer, or an attorney needs, and none of it is visible from the stain.
How do you find mold behind a wall without opening it?
By following the water. Moisture meters read the moisture content of building materials through the surface, and a thermal camera shows the temperature differences that wet material creates behind paint, tile, and drywall. Neither one sees mold directly. What they do is find the damp, and mold does not grow where it is dry, so the damp is where we look.
What is the difference between a mold inspection and a mold test?
The inspection is the diagnosis and the test is one of the instruments. Inspection means assessing the property, finding the moisture, and working out what is happening. Testing means collecting samples for laboratory analysis to identify what is present and in what concentration. A test without an inspection gives you a number with no explanation, which is why we never sell one on its own.
Will you find the leak, or only the mold?
Both, and the leak is the more important half. Mold is a symptom and water is the cause, so if the source is not identified and corrected, the mold returns after any cleanup and you pay twice. Our process is built around locating the water intrusion, whether that is a roof, a window flashing, a slab leak, a supply line, condensation on an air conditioning line, or simply a bathroom with no working exhaust fan.
Will you tell me what the cleanup should cost?
We will tell you the scope, which is what actually drives the cost, and we will not quote the work itself, because we do not do it. Your report describes the affected areas, the materials involved, and what the remediation needs to accomplish, in enough detail that two contractors bidding from it are bidding on the same job. That is what stops you comparing two numbers that mean different things.
What if you do not find anything?
Then you get a report that says so, and that is a real result rather than a failed inspection. Documented evidence that the property is clear is exactly what you need for a purchase, a sale, a claim, a dispute, or your own peace of mind. We have never seen a reason to manufacture a finding, because we are not selling the cleanup.
My home inspector already looked for mold. Why would I need you?
Because a general home inspection is broad and shallow on this specific issue. A home inspector covers the whole structure and its systems, and when something looks like mold the appropriate response is to flag it for a specialist rather than to characterize it. We go the other direction, narrow and deep, on moisture, mold, and air quality, with instruments and accredited laboratory analysis behind the conclusion instead of a visual note.
Can you inspect just one room instead of the whole house?
Yes, and sometimes that is the right call, for example a single bathroom after a known leak or a bedroom where a child is symptomatic. We will tell you honestly when a limited scope answers your question and when it will not, because moisture travels and the room with the stain is often not the room with the problem.
Do you inspect the heating and air conditioning system?
Yes, where it is warranted. An air handler, a condensate line, or a return plenum with moisture in it will distribute spores through every room the system serves, which is how a problem in one closet becomes a whole house complaint. Where the system is implicated we assess it and sample the air it is moving.
