About this company
INX Indoor Air Quality is a privately owned, family-run mold remediation company based in West Chester, Pennsylvania. They handle both testing and remediation for residential and commercial properties across Chester and Montgomery Counties, with over 20 years in operation. Mike Cavanaugh runs the business alongside his mother Lori, and the company offers 24-hour emergency service.
What stands out is their documented 7-step process, which they call the "Seven C's" -- from containment construction through clearance testing to a closing report with before-and-after photos. Their website describes using HEPA vacuums, air scrubbers, and antimicrobial coatings. They also offer duct cleaning and commercial dryer exhaust cleaning, which most mold-focused companies do not. Their commercial client list includes West Chester University, Gettysburg College, the US Mint, and QVC.
The company has deep roots in southeastern Pennsylvania. Multiple reviewers describe returning to INX years after an initial inspection, and several note that Mike told them they did not need remediation when he found no mold -- a signal that the company does not push unnecessary work.
A 4.9-star rating across 110 Google reviews is unusually strong. The volume and consistency of praise -- spanning from 2023 through early 2026 -- suggests sustained quality rather than a short burst of good feedback.

This is a family business where the owner, Mike Cavanaugh, personally handles most inspections and client communication. That creates an unusually personal experience -- nearly every reviewer mentions Mike by name -- but it also means the company's quality is tightly coupled to one person. As volume grows, whether that personal touch scales is worth watching.
Mike Cavanaugh (owner, inspections, estimates -- overwhelmingly positive). Nate (project manager -- positive). John (evaluations, estimates, remediation -- positive). Derek (duct cleaning technician -- positive). Tyler (duct cleaning technician -- positive). Lori (Mike's mother, runs operations -- positive).
INX is a strong choice in Chester County, especially if you value direct communication with the owner. Ask for Mike on your initial inspection and get his honest read on whether you actually need remediation. If the scope is large, ask who will manage the project day-to-day and how communication will work if Mike is not on-site.
Keep in mind
- INX does both testing and remediation, which creates a financial incentive to find problems they can then fix. Consider getting an independent second opinion on any testing results before committing to remediation.
- They claim to serve the tri-state area of Pennsylvania, New Jersey, and Delaware, but their office is in West Chester. Confirm they will travel to your location and whether distance affects scheduling or pricing.
- The website uses broad marketing language and self-describes as "the most trusted mold remediation company in southeastern PA." Judge them by the review evidence and your own experience, not by the website copy.
- With zero negative reviews in the last 18 months, there is no recent complaint data to evaluate. This is a positive signal but also means there are no warning signs to flag.
