Professional Commercial Mold remediation

Commercial mold is a business problem, and we treat it like one. We inspect & test first, so you know exactly what you're dealing with. We remove contaminated materials and fog what removal can't reach, air included. Then an accredited third-party lab verifies the results. Every job ends with documentation you can share and a 1-year mold-free guarantee.

Why Is Claro Number #1 Choice For Commercial Mold remediation?

Inspection & Testing Before Treatment

We never guess at scope. Every job starts with inspection and lab testing, so the plan you approve is based on evidence, and the price is based on the actual problem.

Safe For The People Who Come Back

Our dry fog is non-toxic. When your team returns, there's no residue on surfaces, no fumes in the air, nothing harmful left behind.
icon

Minimal Disruption To Your Operation

No demolition marathon, no weeks of construction. Fogging can take as little as one day, and we schedule around your hours.

Lab-Verified Proof

An accredited third-party lab confirms every result, not us. You get clearance documentation you can hand to tenants, employees, inspectors, or insurers.

A 1-Year Mold-Free Guarantee

Most companies warranty remediation for 30 days, if at all. If mold returns to a treated area within 12 months, we come back and re-treat it at no cost.

1,000s now living or working mold-free

After testing positive for mold in my body, another company told me there was no issue — but Claro's inspection found mold in my decorative pillows and under my sinks that a standard air test completely missed. After a full home sanitization, our whole family was breathing better than we had in 8 years. Can't recommend them enough!

We recently had Nick of Claro - Complete Mold Remediation consult us on our crawlspace and we were very impressed with his expertise. He conducted an air quality test of our house using brand new technology/equipment. He quickly put any concerns we had about mold issues to rest with these precise measurements. We would recommend him to anyone who is looking to understand how to make their home healthy and safe.

Professional, courteous, patient, and thorough! During recent repairs, a serious mold infection was discovered.  My whole house was treated without the need to tear out walls just to find mold. The treatment even took care of any mold infection my HVAC system. I would not hesitate to recommend Claro to anyone. 10/10, no notes!

Jamal treated my house today and was fantastic about answering all my questions. Everyone has been so professional and friendly. With the expectation that I will soon feel better from a clear air quality, I will be recommending this company to all of my family and friends who may be sensitive to mold as I know how difficult it can be to get rid of!

I used Claro for mold remediation 1 month ago. We found mold growing around a bathroom vent. We had them clean up the growth on the ceiling and perform a full house duct cleaning. I have a large house with a lot of vents so the price was very fair! They were able to perform a large job in 2 days. Now, one month later and I must admit my "mild allergies" are gone, no scratchy throat. I am very impressed with this company and Nick's attention to us when we called upon them.

The first of its kind here in town. So great to have a safe mold remediation option in STL. There is nothing better you can do for the health of your family than making sure your house is mold-free! They offer mold inspections and make it easy.
