Rebecque D · Answer

I believe they may be caused by moisture.

Linda Y · Answer

It could be the surface has worn away.

Lyn Johnson · Answer

Excessive moisture underneath the floor can cause this.

Janet Pizaro · Answer

Agree to much moisture stayed on the floor.

Mary-Ann · Answer

Usually this is caused by the wrong adhesive being used under the vinyl. There is only one solution-tear it up and put a new underlay down before installing more. Sometimes house insurance will cover this kind of problem.

This happened to me. live in a Mobil Home. There was a leak in a pipe, small leak.
 The water traveled along the pipes. It was getting all the floors wet   underneath and they were staying wet. Then we were getting the floors soft. Well my husband checked under the trailer. We had to rip up the floors and tile and replace it all. Mold and mildew can get into the wood floors. This is a bad problem. Check for leaks, pull up your tile and look. A small under the  got a wall wet and caused the bottom of a wall to rot, mold set in there.You can do the job yourself cheaper. Check for leakage first.

You got water leaking someplace. Water finds lowest point, or your floor might be over a crawl space that has accumulated water and is now throwing up mold. Is there a nearby water pipe someplace, it could be leaking.

As Mary Ann stated from Canada -it has to do with the underlayment and the adhesive used ... I had a vinyl floor that did the same - not the entire floor but places ... I was told by another tile company this was the issue.

Barb Gimbel · Answer

There needs to be moisture for mold to grow... or at least humidity. If you cannot find a leak, there may just be a condensation problem. Quite often in Canada, our concrete basement floors feel damp even though there aren't leaks. Some things that can cause that dampness are interior moisture sources such as humidifiers, unvented clothes dryers, bathrooms, and cooking, as well as the moisture in concrete after construction.

This same thing happened to me in my kitchen. I had light blue and cream vinyl, I discovered a slow leak and it was going under the vinyl little by little until it started turning dark with mildew. The only thing to do is take it up , find the leak and get rid of mildew before putting new floor down.

Pam · Answer

I sure hope it is the glue. If mold or a leak, it can be a big expensive fix.

Sheila D · Answer

You might need to call in a remediation company. The can tell you if it is active mold  or old stain.  If active they will have a game plan.

I have no answer, I just want to wish you good luck. It is no fun having a problem like this.

Lynn, I have had this problem...Started in a small area then continued to spread...My personal opinion is that the plastic roll sheeting that the builders put down just before the concrete is poured, shifted. Thus allowing the moisture to come up from the ground. That visqueen is your moisture barrier.

Sandy Hartnett · Answer

Seems like mold to me.  Good luck...hugs

Ginger Johnston Adams-Ricks · Answer

I had a problem in our bathroom of black spots appearing on the linoleum. When the new sheeting was put down the old one that was glued down wasn't removed. The wax ring allowed water to seep between the two layers thus getting the top layer wet on the underside. This is what caused the black spots. It was not mold.

Asphalt

PattyB · Answer

Happened in my kitchen in front of the refrigerator. It was moisture build up from the fridge exhaust, causing mold. Had to remove the flooring and replace.

Nick · Answer

Do you have a pet?

Nick · Answer

Looks like water spots that were there for some time

Cory · Answer

Probably from the rugs

Sherry H. · Answer

It could be water under flooring and mold. It needs attention right away before it spreads more. No one should be breathing mold !! :( Good Luck
