When you spill something on your carpet, do you clean it up? Some might just dab it with a paper towel to get the moisture out and call it quits, but this is not always going to be enough. There are few things worse than having mold growing under your carpet, since it can go unnoticed for a long time only to be detected when it has spread very far. Mold could grow both on top of your carpet, as well as, underneath it. Worst case scenario, you will end up with costly repairs, needing to replace your carpet completely.
Carpet that has been wet for more than a day should be checked, since it is possible that mold started growing already. Since mold can bring about many different health effects, it is important to be thorough when checking, and if the infestation is serious, you will need to have a mold remediation specialist help you remove it.
