Due to an A/C leak, I'm having some moldy drywall replaced around the unit. The studs in the area also have some mold on them. The contractor that I've hired to do the job says that he'll clean off the mold with outdoor Clorox and then seal the studs with urethane. I've been doing some reading about using bleach to treat mold on porous surfaces and also the possible danger of sealing with urethane if the mold isn't completely gone (possible dry rot of studs later on). Does anybody have any opinions about this or suggestions? I've been reading a lot about Concrobium and I'm wondering if I should suggest to the contractor that he use that instead. Thanks!

I experience this all the time. Contractors with absolutely no formal training addressing mold issues.

Bleach is usually not 100% effective on porous surfaces such as wood or drywall. Bleach does not always reach the "root" structure of mold.

The proper way to address the studs would be to have them replaced. If you do not wish to replace the infected studs, they should be treated to kill the mold and then sanded to remove the infected area. All of this should be done with the use of an air scrubber and personal protective equipment.

Due to health concerns, I always recommend any and all mold remediation be performed by a specialist.

I have never used Concrobium, and to be honest if it is sold at Home Depot, I would have to conduct testing using my lab to determine the worth of the product.
