How Do You Check For Mold In Your House

How To Detect Mold In Walls

How To Test For Black Mold In 5 Minutes

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.

Signs Of Mold Inside A Household

Bubbly/Blistering Walls

Bubble formation on walls is a common sign of mold infestation. Areas with the highest moisture content will mostly have these bubbles. Its important to examine the basement walls, bathrooms, and areas around the window to confirm the issue. Areas near a leaky pipe or window sill are a breeding ground for mold infestation.

In such a case, you might have to scrape down the paint, clean and dry the surface, and patch things up before repainting the wall to fix the issue.

Musty Smell

Usually, a strong, musty, unpleasant odor is a dead giveaway that mold infestation is in progress. The smell is more prominent around damp and moist areas around the house like sink, bathroom, and kitchen.


This is another classic sign to watch out for. When theres excessive moisture indoor, it finds a way to latch onto all kinds of objects including metallic ones. Its only a matter of time before the metal starts to rust due to excess water content in the air.


Mold continues to release tiny spores in the air that you eventually inhale. Although the immune system is wired to fight off these harmful spores, many people contract the flu due to mold infestation.

Therefore, if you cant seem to shake off flu-like symptoms and allergies it might be a sign that you are dealing with mold inside the house. Other than flu, mold can also cause sneezing, coughing, skin irritation, sore throat, and a runny nose.

The Bottom Line On Testing For Mold

The cleanup procedures for treating mold are the same, whether it is black mold or another type, so it isnt always necessary to test for mold if you can see or smell it. But if you have a specific reason for identifying types of mold in your home or suspect you have mold but cant find the source, a do-it-yourself mold test is extremely easy to conduct.

Is Mold Damage Covered By Insurance

Mold damage may or may not be covered by your homeowner’s insurance. It may be covered by insurance when an item already covered under your homeowners insurance breaks accidentally for example, if your plumbing suddenly ruptures and water floods your house, the homeowners insurance will cover part or all of the costs for the plumbing repair and any mold remediation costs necessary as a direct result of the water damage.

But you may not be able to get insurance to pay for your mold remediation costs if the damage is a result of your neglect for example, if youve had a slow leak under your bathroom sink for years and have ignored the issue. If the insurer can determine that the mold damage is a result of your negligence, they likely wont cover mold remediation costs.

Also, most homeowners insurance will usually not cover mold remediation costs after a flood unless you have a special insurance rider covering your home in case of a flood.

To help prevent mold damage, always keep humidity levels in your house between 30 percent and 60 percent, clean up water spills and damp areas right away, and ensure you have exhaust fans in your kitchen and bathroom. And as soon as you suspect there’s mold in your home, contact the best mold removal experts near you.
