How To Find Hidden Subfloor Mold
Even if you have access to professional moisture detection meters, subfloor mold can be difficult to discover. Perhaps the easiest means of detecting a subfloor mold problem are seeing discoloration on vinyl flooring, warping or distortion in areas of flooring, or the presence of malodors.
Because many vinyl sheet materials have an organic paper backing, they are subject to mold growth. Mold will not grow on the vinyl, but the paper backing is an organic food source in this case. At times this mold growth causes a discoloration to the vinyls surface that can be seen by the homeowner.
As plywood and OSB wood products absorb moisture, their layers can separate or warp. Although this is not a guarantee that there is mold present, it is an indication of a potential problem area that requires further inspection.
The best way to determine whether a mold problem exists on a subfloor is to remove the finish flooring material. If the finish floor is carpet and pad, it can be easily disengaged and rolled back to expose the subfloor material. When vinyl tiles or vinyl sheeting is the finish flooring, it usually requires cutting a small piece of the vinyl out to see what lies underneath. When the flooring is hardwood or laminate, it may be possible to remove a small area to inspect beneath it, and then the hardwood or laminate can be reinstalled without doing permanent damage to the flooring.
How Do You Know If Subfloor Mold Is Present
When mold grows on your subfloor it can be very difficult to find. Since it is under your finished flooring, you usually cannot see it. You may however smell it. Most molds produce a musty, pungent, earthy odor. Sometimes a mold-sensitive person will suffer from allergic symptoms when exposed by just spending time in a room containing mold.
Can I Remove Black Mold Myself
If the black mold growth in your home is small enough for you to treat alone, a simple mixture of bleach and water can help. Add one cup of bleach to one gallon of water and apply it to the moldy spots. Apply the cleaner to the mold spot and scrub away the growth. Be sure to dry the area thoroughly when youre done.

You Feel Like You Have A Lingering Cold Or Are Battling Flu

“It is pretty tough to detect until it starts coming through the walls because mold, as you know, is a problem with some sort of leak somewhere,” Hayes-Raitt said. “So the problem starts behind the walls. But if you’re getting sick, it might be because of a mold problem.”
If you’re dealing with symptoms that you can’t exactly pinpoint, it could be that you’re stressed, haven’t been taking care of yourself, or wound up with some sort of virus, of course, but it could also potentially be that you’re dealing with mold.
If possible, Hayes-Raitt said that one of the best ways to determine if the sickness you feel is related to the house or not is to leave for a few days and then return home. If you feel those same symptoms coming on again, it might be the result of something more than a cold or virus.
