We recommend that you upgrade your electrical system every 30 years. Your electrical service is typically the least serviced system in your house. In most cases, underlying issues that need to be addressed are never found until you experience a problem. Many parts of your electrical system can corrode, rot, wear out, or stop working correctly. It’s also important to keep up with changes in the electrical code. Safety is the #1 reason to upgrade your electrical system, so protect your family, employees, or customers.
