There’s Mold! Now What?

You’re finally ready to tackle that basement, closet, or storage room when you spot something you didn’t expect: mold or mildew. Suddenly, your productive organizing session becomes a bit trickier! Discovering these sneaky fungi is very common, especially in New England, where they thrive in humid environments and in warm spaces we don’t air out often. Don’t worry, you aren’t alone, and we’ve got you covered with some safe, smart steps to take to handle the situation.


  1. Think of your health before anything else. If you spot mold or smell that musty odor, take a step back. Avoid moving items around until you determine how widespread the problem is. Disturbing mold can release more spores into the air, which is how it spreads and grows throughout a space. If you have allergies, asthma, or a weakened immune system, step out of the area and consider if this is a project someone else should help you with. Until you determine the extent of the problem, you should consider wearing gloves, goggles, and an N95 mask in order to take a closer look.

  2. Pause and assess. How widespread is the mold? Look around to find out if the mold is visible on items. Check items like wood, cardboard, and fabrics. Mold is usually green, black, brown, or even orange, and many times has a fuzzy or slimy texture. It penetrates surfaces, which can make it difficult to remove. Mildew, on the other hand, tends to be flat and powdery, ranging from white to gray to brown, and grows mostly on the surface of things, which makes it easier to clean off (it might look like dust).

  3. Figure out the source. What caused the mold? A leaky pipe, rooms that are not properly vented, forgotten damp boxes, or even just too much humidity? Finding the source is key because cleaning up mold without fixing the moisture means the problem will likely come back.

  4. Decide what stays and what goes. Some things can be saved while others are best let go. Nonporous items like plastic or glass are usually safe to wipe down. Use a mixture of detergent and water to scrub away visible growth. For tougher spots, diluted bleach (1 cup bleach in 1 gallon of water) can help. (Do not mix bleach with ammonia or other cleaners!) Soft things like paper, cardboard, or carpets and fabric that have visible mold are likely unsalvageable and should be thrown away. Slowly and carefully dispose of items in sealed garbage bags to prevent spores from spreading further. It can be sad and frustrating to have to discard your belongings, but it’s important to remember that keeping items infected with mold isn’t worth your health and safety.

  5. Consider if the job is big enough for a pro. You can often clean areas smaller than ten square feet by yourself. But if you find a big patch, or if mold is on the walls or insulation, don’t take any chances. This is where a professional can help; they have the right gear and the knowledge to handle it safely.

  6. Prevent future mold and mildew. Once the problem area is handled, clean and disinfect the rest of your space to give it a fresh start. If you were storing your belongings in cardboard boxes, we recommend using plastic bins instead, as these can be wiped down and do a better job at keeping items dry. If you don’t already have one, consider investing in a dehumidifier to help with dampness and air flow, keeping the humidity level set to lower than 50%. If your pipes need fixing, a room needs better ventilation, or the foundation lets water into your basement, it’s best to take care of the problem immediately before it creates more issues in the future!


Every organizing journey has surprises; sometimes they’re fun and sometimes they’re downright challenging. Discovering mold or mildew can feel like a setback, but handled the right way, it’s also an opportunity to make your space cleaner, drier, and truly safe. You might even notice afterward that you have fewer allergy symptoms and more energy! Using the steps above, you’ll be able to turn your home into one you can use and enjoy with peace of mind.
