Mold and mildew can significantly damage your flooring, but more importantly can cause health concerns like breathing problems, unpleasant odors and negatively impact the look and feel of a space.
In the majority of cases, mold develops under the carpet first. So when you identify a spot of mold on your carpet the problem underneath will often be far too widespread for a topical mold treatment and changing a couple of tiles. Instead you will require a full replacement, along with mold treatment and removal.
In other words, it’s extremely costly (not to mention disruptive for your whole organization) to fix mold and mildew problems after they’ve happened - and wherever possible, prevention is definitely better than cure.
