Mold Testing and Inspection in Salt Lake County
Keystone Restoration inspects and tests for mold, using air sampling, before any remediation starts in Salt Lake County, plus Davis, Utah, Summit, and Wasatch Counties. We trace the moisture with commercial moisture meters and thermal cameras, document what we find with photos and video, and test where it changes the scope. We don’t do post-remediation testing on our own jobs; an independent tester is the right choice for clearance. Call (801) 948-2501.

The Inspection
What Does a Mold Inspection Actually Look For?
A mold inspection is really a moisture investigation. Mold needs water to grow, so the useful question is not only “is there mold?” but “where is the water coming from, how far has it spread, and is it still wet?” The EPA’s mold guidance puts it plainly: the key to mold control is moisture control.
On an inspection we look at three things:
- The visible growth, including what kind of material it’s on. Mold on a tile backsplash and mold in the paper face of drywall are very different jobs.
- The moisture behind it. We use commercial moisture meters and thermal cameras to find wet framing, subfloor, and drywall that look fine from the room. A musty smell with nothing visible usually means the moisture, and the growth, is inside a cavity.
- The cause. A slow supply-line leak, a shower pan, a roof or window leak, groundwater in a basement, or condensation from poor ventilation. If the cause isn’t fixed, the mold comes back.
Everything is documented with photos and video so you, your insurance adjuster, or a buyer can see exactly what we saw.
When to Test
When Is Mold Testing Worth Doing, and When Isn’t It?
Testing isn’t always needed. The EPA says that in most cases, if visible mold growth is present, sampling is unnecessary, and that there are no EPA or other federal limits for mold or mold spores. The CDC also says you don’t need to know the type of mold to remove it.
Testing before remediation is worth it when it changes the decision:
- You smell mold but can’t see it, and you need to know whether there’s hidden growth before opening walls.
- Someone in the home has health concerns and wants a documented baseline.
- A home purchase, sale, or rental turnover needs a written record.
- An insurance claim or dispute needs evidence of what was there and how far it went.
When testing is useful, we do it before remediation, so the scope is based on what’s actually there rather than a guess. We use air sampling for that initial test.
Our Policy
Why Doesn’t Keystone Restoration Do Post-Remediation Testing?
Because grading our own work would be a conflict of interest. The IICRC S520, the industry standard for professional mold remediation, includes an initial inspection before the work and post-remediation verification after it. We think the verification step is more trustworthy when someone other than the remediation company does it.
So here’s how we handle it:
- Before: Keystone Restoration inspects and, where needed, tests, then writes the scope.
- After: We don’t test our own jobs for clearance. If you want a clearance test, hire an independent tester with no stake in the result. We’ll share our photos, moisture readings, and scope with them.
The EPA also offers a common-sense checklist for knowing a cleanup is finished: the water problem is fixed, the mold is removed, no visible mold or moldy odor remains, and the area stays dry when you check it again later.
Next Steps
What Happens After the Inspection?
You get a straight answer: what we found, where the moisture is coming from, and what it takes to fix it. If remediation is needed, the scope is written from the inspection and any test results. The scope covers containment, removal of affected materials, HEPA filtration, cleaning and treating the structure, and drying.
Most mold jobs take 1 to 3 days. After the work, the area airs out for an hour or two before anyone goes back in. If removed drywall, insulation, or flooring needs to be rebuilt, our sister company Keystone BuildWorks, a licensed and insured contractor, handles the rebuild as one coordinated job. For typical price ranges, see our mold remediation cost guide.
Direct Insurance Billing
Will Insurance Pay for a Mold Inspection?
Coverage depends on your policy and on what caused the mold, so check your policy or ask your agent. Mold from a sudden, covered water loss is handled differently from mold caused by a long-term leak or humidity. Our page on whether insurance covers mold explains the usual patterns. If it is a covered loss, we bill your carrier directly. Either way, the inspection documentation (moisture readings, photos, and video) is what an adjuster will want to see.

Before We Arrive
What Should I Do Before the Inspection?
A few steps make the inspection faster and more accurate:
- Don’t clean, paint, or spray the area. Bleach or paint over mold hides the extent of the growth and doesn’t fix it. Leave it as it is so we can see what’s there.
- Stop any active leak if you can do it safely, by shutting off the fixture or the main water valve.
- Note the history. When did you first notice the smell or staining? Has there been a leak, flood, or roof problem in that area? Was it dried professionally? That history often points straight to the moisture source.
- Keep the area closed off and avoid running fans that blow air across the growth.
- Gather paperwork if you have it: a home inspection report, past repair invoices, or photos of an earlier leak.
If you’re buying a home, the inspection can be scheduled inside your due-diligence window, and the documentation gives you something concrete to bring to the seller. If you just bought a home and found mold the inspector missed, our post on mold found after buying a house walks through what to do next.

Straight Answers
Mold Testing and Inspection Questions, Answered
Do I need a mold test if I can already see mold?
Usually not. The EPA says that in most cases, if visible mold growth is present, sampling is unnecessary, and the CDC says you don’t need to know the type of mold to remove it. What you do need is to find the moisture source and how far the growth has spread, which is what an inspection is for.
Does Keystone Restoration test after remediation?
No. We test before remediation, when it helps set the scope. We don’t do post-remediation or clearance testing on our own jobs, because grading our own work would be a conflict of interest. If you want clearance testing, hire an independent tester; we’ll share our documentation with them.
How do you find mold behind walls without tearing them open?
We use commercial moisture meters and thermal cameras to find wet framing and drywall from the room side, then confirm with targeted checks. A persistent musty smell, staining, bubbling paint, or a past leak that was never professionally dried are the usual clues.
Is there an official safe level of mold in a home?
No. The EPA notes that no EPA or other federal limits have been set for mold or mold spores. That’s why the goal is to remove growth and fix the moisture rather than chase a number.
How long does mold remediation take after the inspection?
Most mold jobs take 1 to 3 days. After the work, the area airs out for an hour or two before anyone goes back in.
