Hi, I have a rental property with an outside separated laundry room. There was a leak in the laundry room which caused some mold build up. I have a handyman who says he has mold remediation experience and he knows how to get rid of it. The tenant is insisting I go through a licensed and mold remediation expert. Is it required by law? What are the risks of not going with a licensed person. Any response will help, thanks!

I would go with your handyman. It is really none of their business who you use and I doubt the situation is that dire to begin with.

What does the law say in your city or state?  How large of an area is affected?  What kind of fungus is it?  I always use mildew or fungus since "mold" is scary?  Usually small patches do not require a licensed remediator.  See what the law requires then you can inform your tenant.

There are a number of options about remediation that need the be discussed whenever you find mold, depending on what kind it is....  Number 1 consideration are the current State laws regarding the proceedure in both notifications and proper remediation.   My advise would be to contact your local city/county and or state regulators to determine the appropriate course of action.  Best news is its location outside the living area.  Bad news is it's there.  Best Luck!
