I have lived I my house for 18 years and have never had a mold problem.

I recently have been remodeling. As part of the remodel I removed a 3'x8' window in a bedroom and patched the inside whole with drywall.

Four days ago the Drywall Contractor applied the second coat of joint compound. The door has been open during the day and closed at night, with the inside temperature around 70 degrees during the day and 62 degrees at night.

Today I noticed mold growing on and around the joint compound. Should I be concerned? Or, is this just a tempory problem until the joint compound dries?

I have attached a photo

Thanks
