If you removed the flooring in your kitchen and found mold underneath it, you need to take steps to take care of this problem as soon as you can. Fortunately, there are things you can do to get the mold out, two of which are listed below.
Remove Mold Yourself
If you think the mold is contained in one area you can try to remove it yourself. There are products on the market made to do this. You can also make a solution on your own. Mix 50/50 water and white distilled vinegar in a spray bottle. Thoroughly spray the molded area and then scrub with a hand scrubber.
You can also use a mixture of borax and water to kill the mold spores. If you do use this mix it the same way as you do the vinegar and water. When working with borax you need to wear gloves and protect your mouth and nose with a mask.
When the mold is removed purchase a mold preventer product. This is a spray that is used to prevent the mold spores from coming back again. There will be complete instructions on the bottle that you purchase.
Hire Mold Remediation
If you want to be sure that all mold is removed from your home, you can hire a mold remediation company. Since you have mold underneath your flooring, you may have mold in other areas of your home.
Mold needs moisture in order to grow so you likely had some type of water leak on your kitchen sub-flooring at some point. The mold remediation company will check what could cause this and check other areas of your home for sources of water leaks. They will look at the plumbing pipes in all rooms in your home. They will check your dishwasher and washer to ensure there are no leaks in them. Some leaks may be so small that you would not be aware of them.
Once all mold is found, the company will start the cleanup process. They may have to peel away paint, pull up floorboards in other areas, and more. They will use strong cleaners to remove the mold and take steps to prevent the mold from coming back. They have equipment that they can use that will detect mold spores.
To help you understand the process of removing mold, the mold remediation company in your area will give you much more information.
