Mold is a problem that most homeowners dread. Not only is it unsightly, but it can also cause health problems and damage to your home if it’s left unchecked. Unfortunately, mold is a common problem in many homes, and it’s not always easy to spot. But with a few simple tips, you can potentially spot mold growth in your home before it takes over. 

Let’s break down how to find mold in your house.

1. Check for signs of moisture

Mold thrives in moist environments, so the first step in finding mold is to look for any signs of moisture. This could be anything from a leaky pipe to condensation on windows. Check the basement, attic, and any other areas that are prone to moisture, and keep an eye out for water stains, dampness, or musty odors.

2. Check dark, undisturbed areas

Mold likes to grow in dark, undisturbed areas, so it can sometimes be challenging to find. Check places that are hidden from view, such as behind furniture, in between walls, and under carpets. Use a flashlight to help you see into dark corners and crevices.

3. Look for visible mold growth

Sometimes mold can be seen growing on surfaces. Look for black, green, or white spots on walls, floors, ceilings, or any other surface that may be damp. Keep in mind that mold can grow in colors other than black, green, or white, so don’t discount other colors that may signify mold growth.

4. Use a home mold test kit

If you’re still unsure whether you have mold in your home, you can use a home mold test kit. These kits are available at most home improvement stores and are easy to use. Typically, you will swab or tape a sample of the suspected mold and then send it off to a lab for analysis.

5. Call a professional

If all else fails, it’s best to call in a professional mold remediation company. They have the tools and expertise needed to find mold that may be hidden from view and can provide you with a plan for removing it. They can test for mold in a safe, quick, and accurate manner.

6. Smell for Mold

Mold has a distinct musty odor that is often noticeable before any visible signs are seen. If you smell a musty scent throughout your house, it may be an indication that mold is present. Sniff around the house and determine if there is any area that smells dank. If you identify any, it’s important to locate the area and clean it thoroughly.

7. Monitor for Water Damage

Water damage can often lead to mold growth. You should regularly monitor for any leaks or water damage around your home. If you identify any, it’s important to clean up any water that may exist, and immediately fix the source of the problem. Delaying the repairs will increase the risk of mold growth in the affected area.

Mold can cause allergic reactions that may range from mild to severe, depending on the individual. Some common symptoms include coughing, sneezing, skin irritation, and eyes watering. If you or anyone in your household is experiencing these symptoms regularly, it could be a sign of mold growth in your home. Ensure that you identify and eliminate the source of the mold growth as soon as possible.
