About this company
Illinois Mold Eradicator is a one-man operation run by Jefert out of Richton Park, IL, serving Chicago's south suburbs and surrounding areas. He does both mold inspection and remediation himself, specializing in attic mold. His pitch is straightforward: he charges less than the competition because he does not price by the square foot the way most companies do.
Jefert removes mold using RMR-86, then treats the roots with biocide. For attic work, he seals off the space and runs a negative air machine with three-stage filtration to prevent cross-contamination. He also offers $200 visual mold inspection reports for homeowners about to list their homes, and provides a 10% senior discount. Most attic jobs fall in the $1,500 to $2,500 range with materials included. He offers a lifetime warranty on work where ventilation and roof repairs have been properly addressed.
This is not a large firm with multiple crews. Jefert answers the phone, does the estimates, does the work, and cleans up. Multiple reviewers note he responded on weekends and started work within 24 to 48 hours of first contact.
A perfect 5.0 rating across 230 Google reviews is genuinely rare for any mold company. That volume with no recent negatives suggests consistent execution, though it also means there is no complaint data to test the company's response to problems.

Review consensus
Jefert is praised by name in nearly every review. Reviewers consistently highlight three things: his pricing runs well below competitors (Myrtlean Stockdale said he charged nearly half the next lowest estimate), his turnaround is fast (multiple reviewers report same-day estimates and work starting within 24 to 48 hours), and he explains the mold situation in plain language without pressure tactics. D'Andre Myers noted that another company would not even provide an estimate without paying for an extra service, while Jefert was straightforward. Repeat customer Jim T hired him twice and said both jobs were done with perfection.
0 found across 230 total reviews at 5.0★. No negative reviews found in the last 18 months. With 230 total reviews at a 5.0 rating, there is no complaint data to analyze. This is an unusual situation for any service company.
The absence of any negative reviews across 230 total is statistically unusual. It could reflect genuinely excellent service from a hands-on owner-operator who controls every job, or it could indicate review management. The company actively encourages Google reviews on its website and testimonials page. Regardless, the positive reviews come from a mix of single-review accounts and established Local Guides with substantial review histories, which adds credibility to the overall pattern.
Jefert (owner/sole operator — consistently positive across all reviews). Also referred to as Jeff and Jef by different reviewers.
Ask for Jefert — he is the only person you will deal with. Get your mold inspection from an independent third party first, then bring his estimate in for the remediation work. His pricing and speed are his strongest selling points, but the lack of any negative review history means you cannot gauge how he handles problems when they arise.
Keep in mind
- They do both mold inspection and remediation, which is a conflict of interest. The same person evaluating your mold problem profits from fixing it. Consider getting an independent inspection before committing to remediation.
- This is a solo operation. If Jefert is booked, you wait. Multiple reviewers mention him working long days and weekends, which suggests high demand with no backup crew.
- The website discourages lab testing, saying it is a waste of money. If you want air sampling or tape-lift analysis sent to an independent lab, you will likely need a separate testing company.
- Service area claims are broad: south suburbs, west and north suburbs, and northwest Indiana. Confirm he serves your specific location before scheduling.
