Mold Remediation in Saint Louis, MO
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, tearing out what they can see and leaving airborne spores behind. 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 targets the root causes of mold-related illness. We remove the damaged material, dry the structure, and fog the whole home, so you get less demolition and a more complete result than traditional remediation common in the area.

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 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.
