What is Mold, and Why Should You Worry?

Mold is a type of fungus. It grows in damp, warm, and dark places. In Nairobi, with our rainy seasons and humid apartments, mold finds the perfect place to thrive. The problem with mold isn’t just about ugly stains or bad smells it can also affect your health. People living around mold may suffer from:

• Constant coughing
• Sneezing
• Itchy skin
• Headaches
• Breathing problems, especially if you have asthma

And if you think mold only grows in the bathroom, think again. Below are the hidden places mold hides in your Nairobi apartment yes, even after your cleaner has done their job.

1. Behind Furniture Pushed Against the Wall

When was the last time you moved your couch or bed away from the wall? Probably not recently and you’re not alone. Most people don’t think to check behind heavy furniture unless they’re moving houses. But this is one of the most common hidden spots for mold to grow in Nairobi homes.

Mold thrives in still, dark, and damp spaces. When you push furniture like sofas, beds, wardrobes, dressers, or TV stands tightly against a wall especially an exterior wall you’re cutting off airflow. Nairobi’s changing weather, especially with increased humidity and sudden temperature changes, makes it even worse.

Here’s what happens:

• During cold nights and early mornings, the outside of the wall is cool, while your house inside is warm.
• This temperature difference causes the wall to sweat a form of condensation.
• That moisture gets trapped between the wall and the back of your furniture.
• Since there’s no light or fresh air, the space stays damp and humid perfect for mold growth.

Your cleaner might vacuum or mop around the furniture, but rarely will they move it to clean behind or under it. That means mold can sit there for months or even years, growing slowly on the back of your furniture or wall paint completely unnoticed.

Over time, you may notice:

• A musty smell in the room
• Peeling paint or bubbling wallpaper behind the furniture
• Black, green, or brown patches on the back of wood panels or cushions
• Allergic reactions like sneezing, coughing, or itchy eyes when in the room

If you notice any signs of mold, treat it immediately or call KitutoAfrica for a professional mold inspection.

2. Inside Wardrobes and Cabinets

Think your clothes are safe in your wardrobe? Think again. Mold often grows inside wardrobes and cabinets, especially in Nairobi apartments where humidity and poor ventilation are common problems. This is even more likely when the wardrobe is placed against a cold, outside-facing wall. During Nairobi’s cooler mornings or rainy seasons, the wall may trap moisture, and the back of the wardrobe starts to sweat.  Because wardrobes are dark, closed spaces with no airflow, they create the perfect environment for mold to grow silently.

The wood or chipboard used to make most wardrobes easily absorbs moisture from the surrounding air. Over time, mold can form on the inner surfaces, back panels, and even on your clothes, shoes, bags, or linens. That’s why sometimes; even freshly washed clothes can come out smelling musty. If left unchecked, mold can stain your items, damage leather, and cause respiratory issues.

To reduce mold risk, place moisture absorbers like charcoal, silica gel, baking soda, or dry rice inside your wardrobe. Keep doors slightly open once in a while to let in air and light. And if your wardrobe backs an outside wall, try pulling it forward a few inches to allow air to circulate and prevent moisture buildup.

3. Behind the Refrigerator and Washing Machine

Behind your fridge or washing machine is one of the most ignored yet mold-prone areas in your Nairobi apartment. These machines generate heat during operation, and when warm air meets the cool wall or floor behind them, condensation forms, creating hidden moisture. In most apartments, especially in laundry corners or kitchens, airflow is limited, making it easy for mold to grow undisturbed in this tight, dark space.

Since moving these heavy appliances is not part of regular cleaning, dirt, moisture, and even leaks can build up without anyone noticing. Over time, this leads to a perfect breeding ground for mold. If you’ve ever smelled something sour or musty in your kitchen or laundry area, even after cleaning, mold behind the appliances could be the culprit. You might also find black spots on the walls, tiles, or floor when you eventually move the machines.

4. Around Windows and Window Sills

Windows are one of the most ignored places when it comes to mold. During the rainy season in Nairobi, water often leaks into window frames. If your window doesn’t close tightly, or if there’s no overhang to protect it, moisture builds up.

The wood, paint, or metal around windows starts to break down and that’s when mold shows up. Even if the cleaner wipes the glass, the edges and corners of your windows may still have mold spores growing silently.

5. Beneath Floor Mats and Carpets

If you use carpets, rugs, or mats, you could be living above a mold patch without even knowing it. Sometimes we mop the floor, and then quickly place the mat back before it dries. That traps moisture underneath. Mold then begins to grow on the floor and on the bottom of the mat.

This is common in bathrooms, kitchens, or just inside doorways where people step in with wet shoes.

6. Inside Ceiling Boards and Corners

Water leaks from above are a nightmare in Nairobi flats. Maybe your upstairs neighbor has a leaking pipe, or your roof wasn’t sealed properly. This causes slow leaks into the ceiling and upper corners of your house.

The leak might not be visible at first, but over time the ceiling starts to sag, smell, or develop dark stains. That’s mold quietly growing and feeding on the wood and board inside your ceiling.

7. Under Kitchen Sinks and Bathroom Pipes

These are classic mold zones. Most cleaners will wipe the sink surface and maybe the outside of the cabinet. But underneath where the pipes are hidden inside the cabinet or wall is often damp due to small drips or leaks. Because it’s dark, warm, and usually never opened, this space becomes a mold paradise. Fix leaks early and regularly check under the sink and behind toilets.

8. On Curtains and Behind Blinds

Curtains hang close to windows, which often collect moisture. If your curtains touch wet walls or windows, they can absorb the water and become a perfect place for mold to grow. Fabric mold often smells bad and spreads fast, especially if you don’t wash curtains regularly.

9. Air Vents and Extractor Fans

Ironically, the very tools meant to keep the air clean and dry can become moldy themselves. Most Nairobi apartments have extractor fans in kitchens and bathrooms but they are rarely cleaned. Grease and moisture clog the fans, and the dark, dusty space inside the vent becomes the ideal hiding place for mold.

10. Inside Shoe Racks

Mold also loves your shoes especially leather or rubber shoes that haven’t dried properly. If you store them in a tight shoe rack with no ventilation, mold grows on them and even on the inner surfaces of the rack.
