A small isolated patch of mildew or mold on a hard, washable surface can often be handled with ordinary surface cleaning. If it returns, stays wet, involves porous, soft, swollen or damaged material, or you have a musty smell that continues, submit a maintenance request.
This guide covers that narrow resident-safe boundary: simple surface cleaning, normal moisture control, what not to disturb, and what information to send if the condition continues.
For a Small Patch on a Hard, Washable Surface
The EPA recommends cleaning mold from hard surfaces with detergent and water and drying the surface completely. EPA guidance also recommends protecting your hands and eyes while cleaning mold.
For a small isolated patch on an accessible hard, washable surface:
- Put on household rubber gloves and protective eyewear.
- Use ordinary detergent and water.
- Clean only the accessible hard, washable surface.
- Dry the area completely.
- Use the room's normal ventilation if it operates safely.
- Watch whether the condition returns.
Do not mix cleaning products. Do not escalate from ordinary surface cleaning into stronger chemical combinations, scraping, sanding or removal of building materials to look for hidden mold.
If you have health concerns about cleaning the area yourself, skip the cleaning step and submit a maintenance request instead.
Stop When It Is No Longer Simple Surface Cleaning
If the condition returns or continues after ordinary cleaning, the surface remains wet, or the affected material is porous, soft, swollen, damaged, or cannot be cleaned without removing or disturbing it, stop the resident cleaning and report it.
Do not cut or open walls or ceilings, pull up flooring, remove trim or other building materials to look behind them, scrape or sand materials, open HVAC equipment, or enter an attic or crawlspace while looking for hidden mold or moisture.
What If You Smell Something Musty but Cannot See Anything?
Use normal ventilation and pay attention to where the odor is strongest and when you notice it. You can look around the readily accessible room for obvious moisture, condensation or staining, but keep the check visual and non-destructive.
Do not open walls, move into concealed spaces or take equipment apart to search for a hidden source.
If the musty smell continues or returns, submit a maintenance request and tell us where you notice it, when it is strongest and whether you can also see moisture or staining.
If the larger problem is recurring condensation or unusually damp indoor air, use our humidity and condensation troubleshooting guide.
Should You Buy a Mold Test?
A home mold test is not a required first step before submitting a maintenance request. CDC's National Institute for Occupational Safety and Health does not recommend routine air sampling for mold in building air-quality evaluations. NIOSH reports that visual inspection and detecting musty odors are generally more reliable for identifying damp-building problems.
Submit the actual condition you are seeing or smelling. PMI James River can then determine the appropriate next maintenance step.
What to Include in Your Maintenance Request
If ordinary surface cleaning does not resolve the problem, the condition returns or continues, or you cannot proceed safely, use the PMI James River resident portal.
Include the room and exact location, clear photos, the approximate size of the visible area, whether it is currently wet or dry, whether it has returned after cleaning, any musty odor, any active water you can plainly see, and the safe steps you already tried.
