What they do is mark a place worth a closer look, and that closer look is best done by someone who sees mold in homes every day.

The pages that follow are written for a homeowner who wants a straight answer, not a scare. Rentals add a second party to every mold decision, so this guide works through the order of steps a tenant should follow first. You will find what the signs look like and what each one may point to. The mold removal page explains what a professional visit covers in general terms, and the rest of this guide fills in the detail.
Tell the landlord or property manager first
When it comes to tell the landlord or property manager first, the detail that matters most is the setting around the sign. The first step for a tenant who finds mold is to tell the landlord or property manager, in writing, and to leave the visible growth undisturbed. Mold grows where moisture lingers, so the sign rarely stands alone: there is often damp nearby, a stain that has crept outward, or a smell that is strongest close to the mark. Look at what sits above and beside the spot, because water travels, and the source of the moisture is often a step away from where the growth shows. Those links are clues, not proof, and an inspection is what settles which one applies in your home.
The part of tell the landlord or property manager first that people skip is the follow-up: what happens after the first look. The first step for a tenant who finds mold is to tell the landlord or property manager, in writing, and to leave the visible growth undisturbed. A mark that has been noted once should be looked at again after a few days, because growth that is spreading, a stain that is widening, or a smell that is getting stronger all say the moisture is still active. Either way, the note you made at the start is what makes the second look useful, and it is what helps the professional see how the problem has moved since you first spotted it.
Documenting what you see in general terms
The first thing to know about documenting what you see in general terms is that it is a clue, not a verdict. The first step for a tenant who finds mold is to tell the landlord or property manager, in writing, and to leave the visible growth undisturbed. A single mark cannot tell you what species is growing, how deep the growth goes, or whether the wall behind it is wet, and anyone who claims otherwise from a photo alone is guessing. What the mark can tell you is that moisture has been present in that spot, and that the spot deserves a closer look from a professional. Small, steady observations beat a hurried guess every time.
The second part of documenting what you see in general terms is what people usually get wrong, which is treating the visible patch as the whole problem. The first step for a tenant who finds mold is to tell the landlord or property manager, in writing, and to leave the visible growth undisturbed. The growth you can see is often the tip of a damp patch that runs further than the eye can follow, into the wall, under the floor, or along the back of a surface that looks clean from the front. For a small patch, general guidance may be enough, but for growth that covers more than about 10 sq ft, EPA guidance points to a professional.
Do not disturb visible mold
do not disturb visible mold is the place most people start, and it is worth taking slowly. The first step for a tenant who finds mold is to tell the landlord or property manager, in writing, and to leave the visible growth undisturbed. A careful look tells you more than a quick glance, because mold rarely appears as one neat patch with a clear edge. It can show as spots, as a faint stain, or as a patch that blends into the surface around it, and it can sit beside damp that has darkened the same area. Homeowners in Plainfield see the same pattern, and the local page explains how mold help works in that area.
What follows from do not disturb visible mold depends on how much growth there is and where it sits. The first step for a tenant who finds mold is to tell the landlord or property manager, in writing, and to leave the visible growth undisturbed. A small patch in one corner of a bathroom is a different job from growth that runs along a basement wall or across a ceiling, and the difference is not only size but access: some places are easy to reach and easy to dry, while others sit behind walls or under floors where moisture can linger unseen. That is why the same sign can lead to a short visit in one home and a longer job in another.
Who calls the remediation company
When it comes to who calls the remediation company, the detail that matters most is the setting around the sign. The first step for a tenant who finds mold is to tell the landlord or property manager, in writing, and to leave the visible growth undisturbed.
