In colder regions, frozen pipes are one of the biggest—and most expensive—winter disasters. Take the following precautions to keep yours from freezing and subsequently bursting. First, ensure that exterior walls and garages that house water pipes are properly insulated. If your home is at high risk of frozen pipes, you might keep thermostats set at the same temperature, day and night. Finally, consider installing heating tape on the roof and in gutters with a timer to turn off automatically when not in use.
