Indoor Science has been deemed an essential service and is open for all services, including COVID consulting work.

If you suspect a mold problem, you need a consultant to evaluate the problem that has no financial interest in the cleanup.  Many Chicago area companies offer low-cost mold testing, which is the “loss leader” for expensive and potentially unnecessary mold remediation.


We recommend hiring a mold test company that has no financial interest in mold cleanup, remediation, and chemical products.  Indoor Science is the Chicago area’s top mold testing and mold inspection company for a reason.  We have no conflicts of interest, we won’t try to sell you anything, and we don’t perform remediation.  Any recommendations we make have your best interests in mind. Call (312) 920-9393 to set up an appointment today. We do mold testing in homes, schools, hospitals, and commercial buildings.


What do our mold inspections include?

What you get with most other mold inspections: Someone comes out and collects a mold test in the middle of the property and one outside as a comparison.  Their total time at your property is around 10 minutes. These mold testers will email you the laboratory results with no interpretation.  They will give you no recommendations for corrective measures, or worse, hand you an over-inflated proposal for their company to do the work.


What you get with an Indoor Science mold inspection:

Our mold inspections go beyond basic mold testing. It truly is an inspection.  Our goal is to find any indoor mold growth.  Air samples can be useful, but they do not tell you where the mold is growing.  They also don’t tell you why the mold is growing.   We take time to do a visual inspection of the property, which may not be as exciting as airborne mold tests, but it is the cornerstone of a thorough mold inspection.


We use advanced instrumentation during or mold inspections.  We want to find the underlying moisture source, so we use an infrared camera and scan your walls looking for potential hidden moisture sources.  Questionable areas are further investigated with capacitance and resistance-based moisture meters.

Often we discover a hidden moisture and mold problem that needs to be further investigated, prior to performing a mold test.  We may use a borescope to look inside a wall, underneath carpeting or inside ductwork.

Once we evaluate the problem, we can recommend the best places to collect samples, if any.  For example, if we find a discoloration that appears to be mold growth, we may collect a surface sample for confirmation and identification of type.  Surface samples collected may include tape-lift, swab or ATP tests, depending on field conditions.


Air samples may be collected under normal conditions, or with the air disturbed.  We may also recommend inner-wall sampling, which collects air from behind drywall-based walls.  We use primary calibration equipment for expert level results.  Most mold testers use a simple rotameter that can have a large margin of error.  In fact, most mold testers don’t even know the difference!


Besides air samples, we may take surface samples (tape lift and swabs), bulk samples, mVOC air tests, or ERMI tests on settled dust.  We establish a sampling plan based on what we identify during our inspection, taking into consideration your budget.


Whereas other mold testing companies only hand you a laboratory report, we actually help you interpret the results of the mold tests.  The terms Stachybotrys, Penicillium, Aspergillus and Cladosporium probably don’t mean anything to you.  However, each of those tells us volumes about what is happening in the property.  We will explain what is happening in layman’s terms so you understand the findings.


Most of our services result in a professional report that is reviewed by a certified industrial hygienist (CIH).  Although many other companies call themselves “industrial hygienists”, they probably do not have a Certified Industrial Hygienist on staff to review all technical work.


Finally, we pride ourselves on being one of the few companies that actually provide you with conflict-free recommendations on what to do about any problems discovered.  Most companies either provide no recommendations or provide you with an expensive proposal for their company to do the clean-up work.


Why is that a conflict of interest?  We have seen way too many Chicago-based companies recommend thousands and thousands of dollars of remediation when there wasn’t even any mold discovered! Because you can’t see mold spores, many unscrupulous mold testers fabricate a problem to profit from the remediation work.  Skip all these shenanigans and give Indoor Science a call today.
