Frequently Asked Questions
How much does electrical wiring cost in Texas?
Costs depend heavily on the scope. A single new dedicated circuit runs $200 to $400 for 120V or $400 to $800 for 240V. Wiring a room addition costs $1,000 to $3,000 depending on the number of circuits, outlets, and fixtures. New construction rough-in typically costs $3 to $6 per square foot, so a 2,000 square foot home would be $6,000 to $12,000 for rough-in alone. All prices include standard permits in most Texas municipalities.
How do I know if my home's wiring needs to be replaced?
Warning signs include frequently tripping breakers, flickering lights not caused by the utility, warm or discolored wall plates, a burning smell near outlets or the panel, and sparking when plugging in devices. Homes with knob-and-tube wiring, aluminum branch wiring, or wiring with cloth insulation are candidates for replacement regardless of symptoms. If your home was built before 1980 and has never been rewired, a professional assessment is a wise investment.
What type of wire is used in Texas homes?
Modern Texas homes use NM-B (Romex) cable with copper conductors for most interior circuits. Common sizes include 14-gauge wire for 15-amp circuits and 12-gauge for 20-amp circuits. Kitchens, bathrooms, and garages require 20-amp circuits with 12-gauge wire. For 240V circuits serving dryers, ranges, and HVAC, 10-gauge or larger wire is used. Outdoor and underground runs use UF (underground feeder) cable or wire in conduit.
Do I need a permit for electrical wiring work in Texas?
Yes, most Texas cities require permits for any new wiring installation, circuit additions, or significant modifications to existing wiring. The permit triggers an inspection by a city electrical inspector who verifies code compliance. Your licensed electrician should handle the entire permit and inspection process. Unpermitted wiring can create serious liability issues, insurance claim denials, and problems when selling the home.
How long does it take to wire a new room or addition?
Rough-in wiring for a single room addition typically takes one day for the electrician to run cables, install boxes, and make panel connections. The finish work, which includes installing outlets, switches, fixtures, and cover plates, takes an additional half day after drywall is complete. A full home requires several days for rough-in and one to two days for finish. The timeline depends on the number of circuits, fixtures, and overall complexity of the layout.
What is the difference between 15-amp and 20-amp circuits?
A 15-amp circuit uses 14-gauge wire and can safely deliver up to 1,440 watts continuously. A 20-amp circuit uses thicker 12-gauge wire and delivers up to 1,920 watts. The NEC requires 20-amp circuits in kitchens, bathrooms, laundry rooms, and garages. General purpose bedroom and living room circuits can be either 15 or 20-amp. Installing 20-amp circuits throughout a new home costs slightly more but provides greater capacity for future needs.
