What do mold inspections cost?

mold behind baseboards; mold inspection; cost of mold inspection

This might be the most common question we receive. Unfortunately, there are no “one size fits all” type answers to this question. Think to yourself “How much does it cost to go to the dentist”? Well if you are just going in for a routine cleaning your cost could be less than $100, but if you need major work done it could be $1000’s. Much like seeing the dentist, each mold situation is so unique pricing can vary. Our mold assessments can cost up to $1000 (and occasionally higher for special projects), but the average cost for a typical residential project is about $600. Some major factors that influence the inspection cost are the size of the property, the distance from our office, the type and number of laboratory samples needed, and turnaround time needed.

We deal with mold problems in studio apartments up to large commercial office buildings and everything in between. Inspecting a mold issue on a bathroom window has different needs than a home that experienced a major flooding event. Assessing an attic in a large home in the suburbs with a complex roof design could take a few hours, where checking a wet ceiling from a plumbing leak can be done in a half hour.

We perform assessments throughout the Chicagoland area (and beyond), however, our office is located in Chicago. Depending on the location of your property, this can have a small effect on pricing. For special projects that we do throughout the US, travel may make up a major portion of the cost.

Laboratory samples are going to play the largest part in the total cost of a mold inspection. Some projects do not require any samples, or perhaps just one surface sample. Others may call for a number of air, surface, and dust samples. A healthcare facility may require viable sampling, whereas most properties are analyzed with spore trap samples. As a company, we always aim to maximize the amount of information gathered from sampling, while trying to keep pricing in check. Taking a sample in each room of the house might not provide additional information and can add hundreds of dollars to the cost, therefore, we try to only suggest sampling in areas and situations we think useful information can be gathered.

Hand in hand with laboratory samples is turnaround time. This is the time it takes to receive your report. In projects without samples, it is usually only a day or two before you receive your report. However, if samples are collected we must wait for those samples to be processed at the lab. A typical turnaround time from the lab is 3 business days.  When you add in time for drafting our report which interprets the lab results, our report follows a week from the inspection. In projects that are time sensitive, we can speed up the laboratory results as quickly as 24hr (and in some cases we can process the samples on site, giving you results in about an hour). Jumping to the front of the line at the lab does come at a cost, and weekend or holidays can compound the surcharge even higher.

You may see companies who advertise free or extremely discounted (~$100) mold inspections. If it sounds too good to be true, it’s because it is. Most of these companies are mold remediation contractors, and they use these cheap inspections as a way to get their foot in the door.  They typically suggest extensive remediation and potentially make thousands off of unneeded work. Companies that operate like this do so with an extreme conflict of interest1. The party identifying the problem should not have a financial interest in its removal.

If you are having a mold or moisture problem of your own, and would like to talk with us about what we can do for you, please call our office at 312-920-9393.
