One thing that many people deal with at this time of the year when the weather is so cold are water pipes that freeze up and break.
This can seriously cost a whole lot of money if the problem isn't delt with right away.
Here is a video that expains better what can happen if your water pipes break.
A neighbor of my parents were away from their home for a few days while the man of the house was hospitalized and while they were gone their pipes busted and by the time it was discovered and the water shut off, the floors of their bedroom, bathroom, hallway, living room and spare room all had to be torn out and completely replaced. It really doesn't take much time for water to cause a lot of damage.
So before it is to late make sure that your pipes are wrapped with insulation, heat tape or something along those lines to make sure this doesn't happen to you!!
