About this company
Natural Mold Solution is an owner-operated mold company based in Brentwood, TN, serving the greater Nashville area including Franklin, Spring Hill, and Columbia. Co-owners Michael Biscotto and Rob Rawson run the business together and personally inspect every job before and after the work is done. They focus exclusively on mold — testing, remediation, and prevention — for both residential and commercial properties.
The standout here is their treatment method. They skip bleach entirely, instead using a custom two-part spray-scrub-and-wipe process followed by antimicrobial fogging. For crawlspaces, they seal foundation vents and install dehumidifiers to prevent regrowth. They also sell and install EnviroBiotics probiotic air systems, which use beneficial bacteria to compete with mold and pathogens rather than chemical disinfection. Air samples go to Hayes Microbial Consulting, an outside lab. They offer a 12-month warranty on mold removal and financing for larger jobs.
Michael and Rob have both completed IICRC courses in applied microbial remediation, water damage restoration, and mold inspection. The company has been operating for several years out of Brentwood and maintains accreditation with the Better Business Bureau.
4.9 stars across 110 Google reviews is exceptional. No reviewer in the last 18 months has left anything below 4 stars. Multiple repeat customers — including realtors and investors who have used them on 8+ properties — keep coming back, which is a strong signal for a company this size.
Services
Service area
Based in Brentwood, TN. Serves the greater Nashville area including Franklin, Spring Hill, Columbia, and Belle Meade. The contact page lists two phone numbers — one for Michael (general) and one for Rob (Nashville area specifically). The service corridor runs roughly 50 miles from Nashville south to Columbia.
Review consensus
Michael and Rob are named repeatedly for picking up the phone, showing up on time, and giving honest assessments — including telling customers they do not need services. Multiple reviewers describe getting same-day or next-day responses. Realtors Sarah Thomas and Deborah Taylor both cite the company as their go-to for meeting transaction deadlines. Several customers highlight that they were not upsold: Eric Peterman compared a $14,000 quote from another company to the $1,995 he paid Natural Mold Solution. Repeat customer Will Baugher has hired them for at least 8 houses. Jenn Mineo and Elisabeth Winkler both note that Rob and Michael spent time advising them even when they did not ultimately need services.
0 found across 110 total reviews at 4.9★. No complaints to report. Zero reviews at 3 stars or below have been posted in the last 18 months.
The owner-operated model drives the consistency here. Michael and Rob personally handle calls, inspections, and follow-ups, so customers deal with the same people from first contact through completion. This removes the office-vs-field disconnect that generates complaints at larger restoration companies. The trade-off is capacity — two owners can only handle so many jobs, which may mean longer lead times during busy seasons.
Michael Biscotto (co-owner — praised for responsiveness, knowledge, honest assessments, and personal follow-through across dozens of reviews). Rob Rawson (co-owner — praised for responsiveness, willingness to spend time explaining findings, and not upselling).
This is about as clean a review record as you will find for a mold company. Ask for Michael or Rob directly — they are the entire operation. Because they handle both testing and remediation, get a second opinion on any test results before signing a remediation contract.
Keep in mind
- They do both testing and remediation, which is a conflict of interest. The same company that tells you whether you have mold also profits from fixing it. Consider getting an independent test to confirm their findings before committing to remediation work.
- They sell EnviroBiotics probiotic air purification systems and offer a discount code on their website. This is an upsell channel — ask whether the probiotic system is necessary for your situation or optional.
- The website lists no physical office address. Both owners operate out of Brentwood, TN, but the service area spans Nashville to Columbia, roughly a 50-mile corridor.
- Most of their documented work is in crawlspaces and basements. If your mold issue is in living spaces, walls, or HVAC systems, confirm they have the same depth of experience above-grade.
