Mold is the most common source of indoor air quality problems in houses and apartments.

  • Musty, earthy odors
  • Asthma or allergy symptoms while indoors
  • Difficulty breathing
  • Skin rashes

How to Check for Mold

To check for mold, look for discoloration on surfaces with a slimy, fuzzy, or powdery texture.

Mold can sometimes grow in hard-to-spot places, such as behind wallpaper, inside vents, or in an attic or basement.

Start by inspecting your house or apartment for leaky pipes or any other signs or sources of moisture. Mold always needs moisture to grow, so look in areas and surfaces that have been recently exposed to water, humidity, or condensation.

When you check for mold, youll want to answer these 3 questions:

  • Do you have mold?
  • What caused it?
  • Where is it located?

With answers the questions above, youll have a much higher chance of successfully getting rid of the mold and keeping your house or apartment mold-free in the future.

If you discover mold growing in your home, its important to take steps promptly to find and remove it.

If You Suspect Mold in Your House or Apartment

Here is a list of common places to check for signs of mold:

  • Ventilation ducts and plumbing lines
  • How To Tell If Mold Is Toxic

    Mold is a nasty problem to deal with for any home or business-owner. In the wake of a disaster such as a storm, its possible for mold to start growing in as quickly as 1-2 days. Whats even more alarming is when that mold turns out to be toxic, posing a serious risk to you and anyone else on your property.

    To clarify, its not that the mold you are dealing with in and of itself is toxic. Its that certain strains of mold, like the notorious Stachybotrys chartarummore commonly known as black moldproduce mycotoxins. Its these mycotoxins which may cause a burning sensation in the throat and lungs, chest pain, persistent coughing, fever, rashes, and migraines. Prolonged exposure to Stachybotrys may lead to serious health issues, including breathing problems, fatigue, sinusitis and other pain in the sinus cavities, and even depression.

    In The Shower And Bathtub

    Showers and bathtubs are one of the most common places you may find mold. With repeated use, these areas tend to be damp most of the time. If you arent properly ventilating during and after your shower or bath, mold spores will thrive. But mold isnt always visible and obvious be sure to check for mold on your shampoo bottles, washcloths and loofahs, shower curtain, in and around the faucet and shower head, and in the tile grout.

    Do You Have Toxic Mold In Your Home

    How to tell if you may be dealing with toxic mold in your home:

  • Watch out for a nasty smell: The most common sign that you arent dealing with any ordinary mold is a musty odor, sort of like rotting dirt of rotting leaves. Mold thrives in dark, damp, humid environments, so follow your nose to cramped spaces in your home if you detect an unusual smell.
  • Look for visible growth: While toxic mold often hides in your walls, crawlspace, or attic, sometimes it is out in the open, too. In these cases, you are likely to see dark rings or spots on the ceiling. While this mold is not necessarily toxic, you will want to have an inspection done right away to make sure.
  • You continue to see stains, even after youve wiped the mold away: It is not advisable to try and clean up mold yourself. However, if you have disinfected and wiped away a moldy area, and continue to notice staining on the walls, its probably time to call for that inspection you neglected before.
  • Pay attention to the color and consistency: We already talked about black mold above, though its more accurate to say that Stachybotrys chartarum has a greenish-black hue. Toxic mold can also have a grayish, soot-like texture, or a slimy, wet surface. In some cases, you may even notice furry orange or brown spots. If you find mold with any of these qualities in your home, dont get too close, and call a professional right away.

    Dont inhale too much air if you find that kind of a smell coming from the vents. If you are curious and wanna test the vents, to be sure, then go near the vent and then take a couple of breaths.

    If you find that smell, then just be sure the reason behind it is mold, and you have to get rid of it as soon as possible.

    What Does Mold Smell Like

    Mold has a damp, musty scentsimilar to what you’d smell after opening an old book. “In general, smell is not a good way to determine if there is a mold problem,” said Laureen Burton, a staff chemist and toxicologist for the Environmental Protection Agency . The smell of indoor molds can differ depending on the type of mold, the surface on which it’s growing, and its source of moisture. Plus, she said, some people don’t notice a smell at all.

    The mold smell is caused by microbial volatile organic compounds , which are substances that are naturally produced by molds as they grow. “The health effects of inhaling mVOCs are largely unknown,” said Burton, “although exposure to some mVOCs has been linked to symptoms such as headaches, nasal irritation, dizziness, fatigue, and nausea.”

    How To Detect Mold In Walls

    If there is an area of your home where you think mold may be present in the walls due to smell, a strange appearance of the wall, or any other factor there are a few ways you can test this.

    The simplest way is to probe the area with a screwdriver. If the area is soft or the screwdriver easily pierces the drywall, mold likely has rotted the surface away, and youll be able to see it once a hole has been opened up in the surface. Be careful when doing this and do not do it near any wiring or electrical outlets.

    You could also use a fiber optic camera to look around inside after opening a hole in the wall, but at this point, you may as well hire a professional inspector. A professional inspector has the tools required to examine the wall thoroughly, and ensure that its mold free or detect any potential issues.

We dont use sledgehammerswe use knives and spray bottles to wet down the material. The debris we create is bagged in bags taped shut, and the exterior has to be vacuumed to prevent cross-contamination. Surfaces that cant be removed, like a concrete slab, have to be cleaned and if there is evidence of contamination, have to be encapsulated in an antimicrobial sealant, like a primer.”Beware of remediation companies that offer “mold fogging,” or filling wall cavities with spray foam, rather than full removal of the contaminants.
