Disturbed air = better accuracy

Mold often hides. We use compressed air to stir up dormant spores, improving test accuracy and reducing false negatives.

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.
