Mold & Indoor Air Quality Testing in the Northwest Suburbs
Performed in-house by our own Illinois-licensed inspectors, from our base in Cary, IL. Full panel. Single swab $300. Indoor air quality $475.
The Short Answer
At Ease Inspections performs full-panel mold testing for $500, including surface and air samples with laboratory analysis. A targeted single swab is $300 and indoor air quality testing is $475. We test but do not remediate, so the result is never a sales pitch for our own follow-on work.
Why Mold & Air Quality Matters
Mold needs three things: moisture, a food source and time. Houses supply the last two for free, which means every mold problem is really a water problem that has been running long enough to grow something.
Testing answers two questions a visual inspection cannot. Whether what you are looking at is actually mold, and whether there is a problem you are not looking at, because air sampling picks up spore counts from growth hidden behind finishes or under floors.
What Our Mold & Air Quality Covers
Full panel testing
Surface and air samples sent to an accredited laboratory, giving both what is growing and what is airborne. $500.
Single sample or swab
Targeted testing where visible growth is present or a specific area is suspected. $300.
Indoor air quality testing
Air sampling with laboratory analysis for a broader read on what occupants are breathing. $475.
Moisture source investigation
Thermal imaging and moisture meters to find where the water is coming from, because testing without fixing the source solves nothing.
We do not remediate
We are not a remediation company. Our findings are not a lead-in to selling you a cleanup, which is a conflict of interest worth avoiding.
Mold & Air Quality in the Northwest Suburbs
Water is the driver, and different parts of the Northwest suburbs supply it differently.
Around the City of McHenry, the Fox River and the Chain O’Lakes, a meaningful share of homes started as seasonal cottages and were converted to year-round use. Those conversions sit on tight crawlspaces with retrofitted heat and patchy vapour barriers, which is close to ideal conditions for chronic moisture. We carry crawlspace robots so those spaces actually get evaluated rather than noted as inaccessible.
In Lake in the Hills, Algonquin and Huntley the mechanism is different: finished basements. A finished lower level hides water intrusion behind drywall, and by the time a stain appears the growth behind it is usually well established. Thermal imaging is one of the few practical ways to see it early, and it is included in every inspection we do.
Around Algonquin’s Fox River bluffs and the graded lots throughout Cary, the source is frequently just drainage: grading pitched the wrong way, a downspout dumping at the foundation, a window well with nowhere to drain.

Mold & Air Quality Questions
How much does mold testing cost?
Full-panel testing including surface and air samples is $500. A targeted single sample or swab, appropriate where visible growth is already present, is $300. Indoor air quality testing is $475.
Do I need testing if I can already see mold?
Sometimes not. If growth is visible and the source is obvious, the money is often better spent on fixing the water problem and cleaning up. Testing earns its keep when you need to know what species is present, whether spore counts are elevated, or whether there is hidden growth you cannot see.
Do you remove mold as well?
No, and that is deliberate. We test and report; we do not remediate. A company that both tests and sells remediation has an obvious incentive to find a problem.
What is the difference between mold testing and indoor air quality testing?
Mold testing targets fungal growth specifically, through surface and air samples. Indoor air quality testing is a broader air sample analysis giving a wider picture of what is in the air in the home.
Can you test a crawlspace I cannot get into?
Yes. We use crawlspace inspection robots for spaces that cannot be safely entered, which matters around the Fox River and Chain O’Lakes where tight crawlspaces are common.
