It monitors the air inside your home for radon, mold risk, humidity and VOCs. The first step to avoiding mold is preventing the conditions that allow it to grow.

This allows you to get to the root of the problem before mold starts to grow.

What to Consider When Buying a Mold Test Kit

As we mentioned earlier, the presence of mold in your home isn’t something that should be taken lightly. If you notice mold growth or spores anywhere in your home, call a professional to take a look and offer you a plan for remediation. If you want to perform a DIY test during your appointment with a professional or don’t see any visible spore but suspect there may be mold growth, an at-home kit is a great option. Consider these factors before picking out a mold test kit that suits your needs.

• Type of test: Some kits may only test for specific types of mold or be able to test specific areas of your home. For example, some kits only test the air, and others only test surfaces. Consider what areas in your home need to be tested and what type of kit you’ll need before selecting one.
• Accuracy: Look for kits with high-accuracy results and certified and accredited labs. Since you can read the results at home for most of the kits we selected, ensure that they’re accurate and reliable if you decide to send your samples away for testing.
• Number of samples: If you need to test multiple areas of your home, looking for a kit that offers enough samples is important. You can also purchase more than one kit. Also, if you want to test inside and outside, ensure the kit you select offers outdoor testing. Not all kits do.

FAQs

Do mold test kits really work?

At-home mold test kits are an inexpensive and fairly simple way to test for mold in your house, but there are a few things to consider before you test because mold shouldn’t be taken lightly. Yes, mold test kits can detect mold, but they don’t always show the full picture. They typically can only pick up on surface mold and won’t be able to tell you what’s happening behind walls or in areas that aren’t accessible. It can also sometimes be tricky to interpret the test results; false negatives or positives are always possible. The bottom line is to use a mold test kit to get you started. If you suspect larger mold issues throughout your living space, contacting a professional mold inspector is best. They have more tools and expertise to help you reach the issue’s root.

What do professionals use to detect mold?

Professional mold inspectors start with a visual assessment of your home. They look for visible mold, water damage or areas of high humidity to determine what steps or tests to use next. Inspectors test the air for mold, moisture and humidity. They test surfaces where mold growth is detected and often use tools such as thermal imaging cameras and boroscopes to understand better what is happening behind walls or in HVAC systems. All this information helps them build a remediation plan to remove the mold if necessary.

How do you know if mold is behind your drywall?

Opening up drywall seems like the only way to uncover mold growth. This creates a big mess and disturbs the mold. A few things indicate mold behind drywall. The more obvious signs are visible mold growth, peeling paint or wallpaper and water stains or discoloration. Other signs of mold behind drywall are musty odors or persistent respiratory issues. If you’ve noticed any of these, order a mold test kit and take steps toward remediation.
