Visible Mold Growth


An obvious sign of mold growth is visible mold on surfaces. However many people don’t notice small amounts of mold growth or they mistake it for soot or dirt. In some cases people simply ignore visible mold in their house. Mold tends to grow in dark, moist and warm areas.  If you observe mold growth, even if it’s only small, you should take action immediately. Small mold patches can spread and signs of any mold shows that the conditions in your home are conducive for mold to grow.

Sometimes you might not realize there is mold in your house, especially if it is unusual looking mold.  There are over 100,000 species of mold and certain species will thrive specific conditions.   Some mold growth looks white and thread-like. Other mold appears as clusters of small black spots. Mold can be black, gray-brown, gray-green or white in color. Mold growing behind wallpaper made of vinyl can even appear orange, pink or purple.


Signs of Mold Hidden

Musty Odors

When you have hidden mold growth in your house, often a moldy smell might be your only clue. Don’t ignore mold odors if you can’t see any mold. You should thoroughly inspect your home before any mold problems escalate. Mold produces gasses called microbial volatile organic compounds (MVOC). Many of these gasses are odorless but some have a musty odor, the smell typically associated with mold. If you notice a musty odor in your home, you probably have mold growth, even if you don’t see any mold. Mold often grows in hidden places, like inside walls, under carpets, and inside heating and ventilation ducts.

The only way to really eliminate the mold smell is to remove the mold. Air fresheners, disinfectant sprays, and common household cleaning products may temporarily cover up the smell but they won’t really get rid of it.  Scented candles, incense, and potpourri are some other ways people sometimes attempt to disguise the musty odor of mold, and none of them work very well, either. The only truly effective method of mold odor control is to remediate the mold contamination.


Signs of Water Problems

If you have had any long term moisture problems in your house it’s usually inevitable they will lead to mold growth. If you’ve had some water problems in your home then its very likely that you have mold.

Some signs that you have a moisture problem include water stains or discoloration on walls, floors or ceilings in your house. Seeing these could be a clue that there is mold growing within or behind the material.

Another sign of a moisture problem is surface abnormalities like peeling, bubbling or cracking of the paint or wallpaper. If your walls are bowed, bulging or warped it probably means moisture has gotten into them. Another clue is if the surface of walls or other materials feel damp.



If you see a lot of condensation in your home then it’s a sign that you have a high amount of moisture and hence a sign of mold growth and mold problem. Condensation will occur on surfaces such as glass windows or metal pipes. Mold could be growing where the condensation builds up and collects. Rusting indoor pipes are a sign that you could have a lot of condensation in your house.

Besides the fact that condensation creates a build up of moisture for mold to grow on, condensation can also be a sign that you have a humidity problem in your home. A high humidity level can feed mold and it is another sign that you might have a potential mold problem. Condensation can occur in the attic, crawl spaces and wall cavities.

Water Leaks and Past Flooding

The signs of water problems in homes are usually created by leaks. However if you already know that you have had a water leak (such as leaking pipes or a leaking ceiling) then just that knowledge by itself, even if you don’t see signs of water damage, is a good sign that you might have mold growing in your house around the area where the leak was.

Mold growth from leaks can often be hidden. If the leak was behind a wall or other surface then any mold will probably be hidden behind the surface too. Even if the leak was not behind a surface there could still be mold hidden out of view behind a wall or other surface from water which seeped through.

If your house has been flooded in the past then it’s likely that mold would’ve started to grow. It is critical to eliminate the water or dry out building materials within 48 hours. After 48 hours wet building materials may be conducive to mold growth depending on a number of factors. Any mold would probably be growing in places where flood water remained the longest such as in the basement. Floods can often create mold growing out of view behind walls or under floors.

Allergic Symptoms from Mold

If you are having a problem with allergies it may be a sign that you have mold growing somewhere in your home. Common allergic reactions to mold include sneezing, sore eyes and a runny nose or nasal congestion.

Do you notice your allergic reactions are worse when you’re at home but you feel better when you go out? If so then it’s especially likely you could have mold. If you find that your allergies are worse in some other building, like your workplace, then there could be mold growing there instead.
