Think you may have mold?
Claro St. Louis can help

Mold is more than an eyesore. It's a health risk that thrives in St. Louis's humid climate. At Claro, we start by addressing the source of the problem, remove what needs to come out, and then apply our EPA Safer Choice dry fog treatment to every surface and air space in your home. Once the source is fixed, the fog treatment itself is typically completed in hours. Our process is lab-proven to achieve up to 99% spore reduction, and we back every job with a one-year guarantee — no demolition, no displacement, no shortcuts.

Most mold remediation companies focus only on what you can see, using harsh chemicals and costly demolition that can take days or weeks. Claro is different. Since mold is airborne, it travels throughout your home and will continue to spread, even if the source is removed. As a result, we take a whole-home approach, treating every room from attic to crawlspace with our family-safe, EPA Safer Choice dry fog. That means the air you breathe, the walls you can’t see behind, and the surfaces you use every day are all restored to healthy, mold-free conditions.

Our process doesn't require St. Louis families to move out and targets the root causes of mold-related illness. Because we don't tear out walls or ceilings, you avoid the cost and disruption of traditional remediation methods common in the area, while getting a more complete result.

Our mold remediation process

1

Professional mold inspection

Every job begins with a thorough on-site inspection from our NORMI-certified team, looking for visible mold, moisture issues, and any conditions that could be contributing to a problem. If needed, we'll also collect air samples and send them to an accredited independent laboratory for analysis, giving us a clearer picture of which mold species are present, at what concentrations, and exactly what approach your home requires.

2

Address any moisture sources

Our team will find and scope the work required to address any existing moisture issues in your home so we can address the root cause first. Moisture sources, leaks, or drainage issues must be completely resolved for our treatment to work and prevent mold from returning to your St. Louis home.

3

Family-safe dry fog treatment

This treatment reaches every surface and airspace in your St. Louis home, achieving up to 99% spore reduction without demolition or harsh chemicals.

4

Guaranteed results

After treatment we take a viable air quality test to ensure mold levels are back below acceptable levels. Assuming all moisture issues have been addressed, our results are guaranteed for a year. If the mold comes back, we’ll treat it again free of charge.
