Whole‑home rewiring services in San Antonio, TX

The cost of a whole-home rewiring project primarily depends on four factors:

• The size of your home. Bigger homes tend to have more old wiring that needs to be replaced, which increases the cost of your whole-home rewiring. The overall cost goes up because big rewiring projects require more time, labor and materials.
• The type of original wiring your home has. If your home was originally wired with an outdated method, your rewiring costs will probably increase. For example, if your home was wired with a "knob and tube" method (which is now considered outdated and unsafe), electricians will need to individually remove the tubes and knobs. The removal process is tedious and will increase the amount of time and labor it takes to rewire your home, increasing your project cost.
• The method for the rewiring. Some homes with old aluminum wiring are rewired with the "pigtail" wiring method. The pigtail method is used to prevent aluminum wiring from overheating and is cheaper than a complete rewiring job. Basically, electricians attach copper wire "pigtails" to the ends of aluminum wires at connection points with a connector. A licensed electrician installing pigtails will make sure that the copper and aluminum wires are properly joined and that the connections are correctly terminated. Another benefit of the pigtail method is that it's minimally invasive and doesn't require cutting into walls/drywalls.
• Whether or not you need to replace your electrical panel. If you have an older home, your electrical panel might not provide more than 60 amps. It is highly recommended that you upgrade your electrical panel to 150-200 amps. This is because most homeowners today use more electrical appliances, increasing the power demand that homes need to provide. And an upgraded electrical panel allows you to safely use more electrical appliances compared to an older panel.
