@James Black I finally closed on my triplex in Wakefield earlier this month.

I just purchased the property 3 weeks ago, and one person has painted their kitchen cabinets as well as the front door(interior and exterior with big splashes on the exterior gate) glossy black.

There are numerous types of mold, but black mold is the one we generally talk about.
