Provider snapshot
What this listing says
St. Louis homeowners who want a dry-fog mold treatment that treats the whole house in a single afternoon without demolition, especially in the western suburbs from Kirkwood to Chesterfield.
Best for
- Homeowners in the St. Louis western suburbs — Clayton, Ladue, Chesterfield, Kirkwood — who want whole-house mold treatment without demolition or multi-day disruption.
- Buyers dealing with persistent musty odors or HVAC-related mold where the contamination is behind walls or in ductwork that traditional removal cannot easily reach.
- Health-motivated homeowners working with functional medicine doctors who need documented pre- and post-treatment air quality results.
About this company
Claro is a dry-fog mold remediation company in St. Louis, Missouri, headquartered at 8821 Manchester Road in the Brentwood area. They use Pure Maintenance Technology, a patented process that converts EPA Safer Choice compounds into a sub-10-micron dry fog applied under positive air pressure. The fog reaches inside walls, HVAC ducts, and enclosed cavities without tearing anything apart. A second antimicrobial treatment follows to inhibit future growth. The company claims the entire process takes half a day and you can sleep in the house that night.
What stands out is the treatment method itself. Most St. Louis mold remediation companies use traditional containment-and-removal approaches that involve demolition. Claro skips that entirely — no drywall removal, no negative air machines, no multi-day projects. They also do their own air testing using Instascope real-time analysis and EMLab lab samples, which means the same company diagnosing the problem also sells the fix. They send lab results with a written rubric explaining the numbers, which is more transparency than most testing companies provide.

Review consensus
Dave, the owner, is the dominant name across reviews. Reviewers describe him answering the phone directly, arriving the same day or next day, testing air quality on-site, and explaining results in plain language. Joan Krull noted he showed up within an hour of a late-Friday afternoon call. Multiple reviewers — Michael B, Joe Pham, Grant S — highlight his honesty: telling one customer fogging only made sense after a leak was fixed, and being upfront about what the process can and cannot do. Amy Bartell praised same-day service with independent lab results back within days. Candace C credited Dave with helping resolve sinus issues and migraines tied to mold exposure.
0 found across 20 total reviews at 5.0★. No negative reviews exist. Every review across all 20 is 5-star. There are no complaints to evaluate and no owner responses to analyze.
Dave's personal involvement appears in nearly every substantive review. This is an owner-operator model where the owner handles inspections, testing, customer communication, and treatment scheduling directly. That is a strength at 20 reviews, but it raises a question about scalability — if volume grows, the experience reviewers describe may depend on whether Dave remains personally involved.
Dave / David (owner — praised by Candace C, Frank Armstrong, Grant S, Michael B, Joe Pham, Katelyn Edgar, Joan Krull, Antoine Courbe, John Brady for direct involvement, honesty, fast response, and clear communication).
If you hire Claro, you are hiring Dave. Confirm he will personally handle your inspection and testing. Ask for the lab report directly — not just a summary — and get a second air test from an independent firm if the results recommend treatment. The dry-fog process is fast and non-destructive, but make sure your moisture source is resolved first, because fogging does not fix leaks or replace damaged materials.
Keep in mind
- Claro does both mold testing and mold remediation. The same company that tells you whether you have a problem also profits from treating it. Ask for your lab report directly and consider getting a second opinion from an independent testing firm before committing to treatment.
- Dry-fog technology is not traditional mold remediation. It does not physically remove contaminated materials — it kills mold in place. If you have water-damaged drywall or structural decay, fogging alone will not address the underlying material damage.
- The company has 20 Google reviews, all 5-star. A perfect rating with this few reviews means you are largely taking the company at its word. There are no negative experiences on record to reveal how they handle problems.
- Claro is a multi-location franchise using Pure Maintenance Technology, with offices in Tennessee, Georgia, and Missouri. The St. Louis operation is owner-operated by Dave, but the brand itself is not locally rooted.
