These are the two rooms in your home that require the most maintenance and attention in order to keep them in good shape while you are living in your home. However, it really only takes a casual inspection every once in a while to make sure that no problems with mold or water damage are developing.

In the bathroom, the most important surface is the floor. This holds up everything else in the room and if this goes, so does everything else, so preventing water and mold damage to this surface is extremely important. You can do this by making sure that the floor is completely water tight and there is no way for spilled water to get underneath the flooring installed in the room. If it does, it can cause mold to grow and the subfloor to begin rotting.

Installing Schluter-Ditra, a waterproofing membrane, will give you an extra bit of protection against this, so if you are remodeling your bathroom, you really want to consider adding this to the room. Any other room that could have a major spill of water like a laundry room or kitchen could also benefit from this.

The ceiling can be just as important, since allowing it to become soaked with water can lead to sagging, cracking, and eventual collapse of the drywall. This happens when the steam and heat in the room goes up to the ceiling and has nowhere else to go.

Most building codes have regulations requiring that a bathroom have at least a window or an exhaust vent, but it is best to have both of these, since leaving the window open might not be practical in all cases. Spending a couple hundred dollars and a few hours installing exhaust vents in the humid rooms of the house can help with the maintenance of them and save you money over time.

Something else that you need to do is make sure that water on the floor stays cleaned up as much as possible and that wet items of clothing get washed and dried as soon as possible instead of being left out or thrown in with dry dirty items.
