Bathtub overflow should not be taken lightly...
If you tend to have water splash and overflow from your tub do not assume the water will not be causing any damage to the flooring or sub-flooring. It depends on numerous issues. The seal around your tub to the walls or the flooring might be compromised and the repetitive water over flow can be setting you up for a disaster!
SERVPRO is there to take care of the disaster but this is another situation where preventative maintenance could save you some $$$$. Sometimes the water damage can be so significant that the sub-flooring needs to be replaced. Many times we can dry it out and save you the inconvenience.
Left standing too long and in the proper temperature conditions it could result in mold.
