Mold. It is one of those silent, unwanted guests that you may find lurking in the shadows, or maybe in plain sight, around your home. If you can see, or suspect mold, fortunately, it is quite easy to test for mold around your home.

There are many tricks and tools at your disposal to assist with identifying potential areas where mold can develop long before it gets a grip on your home or property. All you need to do is know where mold tends to grow and prevent the conditions it needs from forming.

In this article, we will look at where mold hides, how to test for mold, and even share with you details on a few do-it-yourself mold test kits you can purchase online to do the job at home on your own without the need for a professional. So, first of all, let’s look at where mold can be found and go from there.

Where Mold Can Hide

The conditions have to be right for mold to develop and grow. This means that there has to be moisture. So, if you have locations in your home that are often damp and humid, or where condensation accumulates, these are key locations to monitor for mold. Also, if you can smell a musty scent or see patches of black, white, or brownish coverings, you have mold.

Here are some of the places to check to see if you may have mold hiding somewhere:

  • In the kitchen, look behind your refrigerator.
  • Under piles of newspapers, magazines, and cardboard.
  • In the walls behind the drywall in spaces where plumbing pipes are located.
  • underneath sinks and vanities.
  • Behind wallboard located around leaking windows.
  • in ventilation ducts.
  • Under wet carpeting.
  • if you have had a leaky roof, check under the backside of ceiling tiles.
  • if there has been flooding of any kind, check behind the affected drywall.

How To Test For Mold

Testing for mold in your house is not difficult if you have the proper tools. This means picking up one of the many different types of mold detection kits available in the marketplace.

They all work in basically the same way. Mold test kits contain tools that you use to “sample” the air or surfaces. You mail your samples to a lab and in a few days, you will receive the results.

The kits cost one price and the lab tests are not always included in that price. For an extra fee, you can have the lab identify what type of mold spores are present in your samples.

The Search For Mold

Before you get to testing for mold at home, you need to take a good look around your home to first see if the conditions are present for the development and growth of mold. You also need to know what you are specifically looking for as mold can look a lot like dirt, grime, and other debris that collects in hidden spaces around your living area.

In this section, we will cover what mold looks like and how to determine if you have a situation that requires the use of mold detection kits.

What Mold Looks Like

Mold is a type of fungus that exists and can be found all around us. The tiny spores that float in the air help mold to spread from one place to another. However, moisture and a temperature between 40 and 100 degrees F are required for mold to take hold.

The most visible type of mold is called mildew and it begins life as tiny black spots but can grow to large colonies over time. The black color that appears in grout lines in showers and sinks backsplashes is mold.

The Difference Between Mold And Dirt

There is a simple way to determine what is mold and what is dirt. This simple mold test can be useful in places where mold looks like it could be dirt.

All you need is a swab dipped into diluted bleach (one part bleach to 16 parts water). Dab the swab on the spot you are testing and if that spot gets lighter in color, then you have mold. This is now the time to get a home mold detector kit as this won’t be the only place it will be found.

Why You Need To Test For Mold

Mildew is not going to cause much damage to your home as it is just a surface mold. But other mold types can lead to rot if left unchecked.

You can easily locate these problem areas with the use of a screwdriver. Just poke the screwdriver at an area you think may contain mold and if the wood is soft or crumbles, you have a serious mold infestation to deal with.

How To Properly Remove Mold

So, you’ve identified potential mold locations and have confirmed them through the use of a mold detector kit. Your next task is to remove the mold before it can cause any further damage to your home or property.

There are several special precautions you should take before and during the process. They include the following:

  • Wear old clothing and footwear that can either be cleaned after you have completed the job or can be tossed out.
  • Wear protective gear including goggles, gloves, and a respirator (N-95 or P-100).
  • While working in a room, have an old box fan running in a window for ventilation.
  • Any moldy carpeting you remove should be wrapped and taped in 6-mil plastic.
  • All mold-infested debris should be double-bagged for disposal.
  • As you work, moisten moldy areas with a garden sprayer to prevent spores from getting airborne.
  • Turn off air conditioning and heating and cover ducts and doors to keep spores contained.
  • When vacuuming, keep the wet/dry vacuum outside.

When you are removing mold, use soap and water. This mixture contains surfactants which will make the mold easier to remove. Once an area has been cleaned, spray it down with an antimicrobial spray. This will assist in preventing the mold from coming back and causing more problems within your home.

Why You Should Remove Mold

Aside from the potential damage caused by rot that develops from mold, some airborne spores can trigger allergic reactions. These spores are also irritants for individuals who suffer from any type of respiratory condition. This is why it is important to turn to professional mold testing when you suspect that there may be some mold growing in your home.
