Where does mold grow indoors?

Mold is a type of fungus that grows in moist environments. It can be toxic to humans and animals, so it's important to know where it’s most likely found and how to remove it from your home.

Mold could be coming from the roof, plumbing leaks, or even leaky windows. Some places to find mold include dishwashers, toilets, showers, and sinks.

These are all locations with water near them which provide excellent conditions for growth! Mold can be hidden in hard-to-reach places like behind the walls, under carpets, and inside insulation or ceilings.

In this blog post, we will talk about where you're most likely going to find and prevent mold in your house as well as ways to detect it before it’s too late!

If you've found mold in your home, you need to act fast before it spreads and causes a health risk to you and your family. Contact Mold Removal Winnipeg to take care of mold removal and clean-up.

If you're asking where do you find mold in a house, then be on the look for growth in these high-moisture areas?

- Dishwasher mold: Can grow in the dishwasher because it's moist and almost always on. A washing machine is the same.

- Shower mold: if you have a leaky shower or your bathroom doesn't get enough ventilation, molds could be growing inside of your shower walls or exhaust fans.

- Sink mold: sinks are usually near water so they are a great place for it to grow.

- Toilet mold: if your toilet isn't kept clean, mold can start growing inside of it! Be sure to keep your bathroom as dry and ventilated as possible so it doesn't have the chance to grow here. If you do find it in these areas be on the lookout for other signs it may be growing in your home.

- Spots on walls or ceilings: mold loves to grow on smooth surfaces like drywall and ceiling tiles, so look for dark and wet spots on your walls and ceiling.

Musty odors: mold has a distinct smell, so if you notice musty smells coming from your bathroom or any other room in the house be sure to investigate where it's coming from! It can grow anywhere indoors when given enough time and moisture (namely water).


Unfortunately, mold isn't always visible. Growth may be on the inside of your walls or in other hard-to-reach places, and you might not be able to see it. If mold is growing where you can't see it, check for these signs:

- Water stains on ceilings and especially near leaky windows or roofs. This could have been caused by a plumbing leak or mold on your roof!

- Air quality changes: if you've noticed that the air in your home doesn't smell quite right, it might have been growing somewhere where it’s hidden. Check for mold and be sure to contact professionals like Mold Removal Winnipeg as soon as possible to take care of a potential problem before it starts spreading throughout your home.

Here are some of the most common areas in the house you're likely to find molds.

Mold In Basement

Mold growth in your basement is a very common problem for homeowners. Basements are often damp, and mold likes these conditions. If exposed to enough moisture or high humidity levels, it will start growing!

The cool air on the floor causes condensation to form when it comes in contact with humid air. This can lead to moisture and ultimately mildew or mold forming if left untreated for a long period.

If you're living with growth on the floors or walls of your basement or any other part of your home, don't panic. Mold Removal Winnipeg has been removing mold from basements for years and we can help you get rid of mold before it's too late.

Mold In Crawlspace

Crawlspaces are another common problem for homeowners. Crawl spaces often aren't ventilated very well so any moisture that seeps in will be more prone to mold growth than other parts of the house.

You've been wanting to check out your crawl space for a while, but every time you go in there it's dusty and damp which feeds the mold. Your dirty clothes have started growing spots on them because of all that dust from down below. Don't let this continue with no intervention on your part!

To keep your crawlspace clean and dust-free, check it out once a month. Make sure to clear any messes or dirt in the corners, walls, ceiling, and floor of this space as well.

Mold Behind Walls

Mold behind walls is a common problem that can go unnoticed for years without the homeowners realizing it.

As you may know, mold needs moisture to grow so if there's mold growing in your house this could be caused by a faulty air conditioner or water coming into contact with drywall or other surfaces where mold loves to take hold.

Infestations behind walls could be coming from a plumbing leak or mold growing in the attic and creeping down through your ceiling.

Mold In Kitchens

Kitchens are another room where growth is common, especially if you don't use these rooms frequently enough for mold to grow on surfaces like walls and ceilings.  Dangerous black mold can also form behind the stove and sink where it loves to grow. 

Kitchen growth can be caused by spores that are brought in on the floor or shoes. If you store your groceries, cooking utensils, and other items near the sink then mold behind walls is a good sign that mold has been growing there for some time now!

It's possible to clean up it using natural cleaners like vinegar and baking soda, but mold on the walls or ceiling of your kitchen can be a sign that it’s growing for a while and needs professional care to remove it al. Other hard to reach places including behind the sink, under the stove in the air conditioning.

Mold In The Attic

If mold is growing in your attic, this usually means there's water damage at least high enough for mold to grow from getting into contact with the roof.

The mold behind your walls or under the sink in your home can be cleaned up, but mold growth on a ceiling is a sign that something has been going wrong for quite some time and needs professional help to get rid of mold.

Mold In The Laundry Room

We've all experienced mold in the laundry room before, mostly because this is where you'll find mold growing.

If you leave damp towels sitting around for too long or fail to dry them properly after washing, mold behind walls might start growing and spread throughout your home over time. Make sure that if you have a washer and dryer at home that mold doesn't start growing behind the washer or dryer. Ensure your clothes are clean and dry and don't leave them on the floor.

Mold In Furnace / Air Ducts

Mold in the furnace and air ducts are problems that homeowners don't realize require a professional mold removal process, until they're breathing in spores all day long, causing a range of health problems.

The furnace and air ducts are a common place for mold to grow because the filters get dirty easily, restricting airflow so it's harder for your HVAC system to circulate clean air throughout your home which means growth is more likely to happen.

Mold In Bathroom

The mold in your bathroom is likely to be growing on surfaces like the shower curtain, tiles, or grout. You've noticed that dampness and musty odors are common parts of daily life in this room, but you haven't done anything about it because mold isn't something most people worry about. All bathrooms need proper ventilation so mold and mildew doesn't form on surfaces like tiles or behind walls.

Mold can also grow in bathrooms if you aren't able to keep these rooms dry and mold-free which is often the case for homeowners who are living with growth on their shower curtains or behind tiles.

If all this sounds like it could be a problem, don't wait until there's an actual mold problem in your bathroom to do something about it. Keep mold out of the bathroom with proper ventilation and mold-proofing behind tiles or on shower curtains.

Mold Behind Tiles

Mold under tiles

One place where mold is particularly likely to grow back even after you've cleaned up a growth issue is beneath tile floors! These types of mold growth are common in basements and crawl spaces where mold loves to grow on tile floors.

Tile mold usually starts forming because the tiles aren't grouted well enough–it can be tough to keep up with this task when it comes to a large floor space like your basement, so you might not even realize that mold has formed between your grout lines.

Mold behind tiles can also form if you live in an area that gets very cold and mold needs a warm, damp place to grow like your basement or crawl space where mold loves to take hold on tile floors.

Mold can grow anywhere in your home if conditions are right. Keep mold out of your home by reducing moisture levels and fixing leaks that may cause higher humidity and damp conditions as soon as possible.
