"Everyone we encountered at 1st Choice was outstanding. They were quick to get to our house to look at the damage from a water leak. Once it was dried out and floors pick they quickly got it ordered and got to work on putting in new floors. Matt and his team went above and beyond on our project. The end result was better that I expected. Matt made sure we understood everything and took the time to explain everything that was going to be done and answered any questions we had. Can’t wait for the next project so we can have them come back. Hopefully not starting with a leak next time."

Mold Testing and Remediation questions, answered by experts

Yes, mold in the basement of your home will affect the conditions upstairs. Mold spores can travel through the air and into the supply vents of your home’s ventilation system. It is extremely important to remove any mold in your basement as soon as possible so it doesn’t affect the health of those living in the house.

Areas of your home may provide an ideal environment for green or black mold. Most molds love moisture and will thrive in wet or damp areas. Some types of mold, such as Stachybotrys chartarum, grow well on materials commonly used in homes, such as gypsum board and wood. Mold may also grow in areas where there are leaks, such as in bathrooms, kitchens, or basements.

In many cases, yes, a damp basement can be bad for your health. Not only can damp air affect your lungs, but it can promote mold growth and pest infestation. Mold spores can be dangerous to breathe in, as can waste particles from insects and rodents attracted to the moisture. Damp, moldy air can also move up into your living area. As such, it’s crucial to fix any basement moisture problems as soon as they crop up.

If you can locate building records, you may be able simply to see what type of tiles (or bonding agent) was used. Any flooring made between 1950 and 1989 more than likely contains asbestos. Asbestos tiles can also be slightly thicker than other tiles and often measure 9” x 9”, 12” x 12”, and 18” x 18. Black mastic was a commonly used adhesive that contains asbestos.

After you clean mildew or mold that appears in your home, you expect the nasty odor to disappear, too. Sometimes, though, the odor can linger after cleaning. To get rid of a mold smell, you may need to clean the area every few days for a few weeks. Use a dehumidifier or fans to try to remove moisture from the area. If the odor remains after a few weeks, you may still have mold or mildew in the area. Call a mold testing professional for another inspection.
