Everything you need to know about electrical in Dallas, TX — average costs, local considerations, and tips for choosing the right professional.
Dallas-Fort Worth grew explosively during the late 1960s and early 1970s, and a great deal of its housing stock dates from exactly the window when aluminium branch wiring and a couple of now-notorious panel brands were being installed. That timing defines residential electrical work here.
Copper prices rose sharply in the mid-1960s and builders switched to aluminium for branch circuits. DFW was building fast at precisely that moment, so the concentration here is high.
Aluminium expands and contracts more than copper with temperature. Over thousands of heating and cooling cycles, terminations at outlets, switches and splices loosen. A loose connection has resistance, resistance generates heat, and heat accelerates the loosening. The end state is a connection hot enough to char the device and, occasionally, to start a fire.
Aluminium also forms an oxide layer that is a poor conductor, which compounds the resistance problem at any joint that is not properly made.
Both are applied at every device and every splice. Cost runs $2,000-$7,000 for a typical home.
What is not adequate: replacing receptacles with CO/ALR-rated devices addresses only the receptacle terminations, not the splices in junction boxes, and many insurers no longer accept it as remediation. Wire nuts on aluminium-to-copper joints are actively wrong; standard wire nuts are not listed for that connection.
Insurers increasingly require documented remediation or decline coverage entirely, which makes this a transaction issue as much as a safety one.
Two brands recur in DFW homes of this era:
Neither is repairable and replacement parts are not a solution. Both are replaced entirely, $1,700-$3,300 for a like-for-like swap.
Check the label inside your panel door. It takes five seconds and it is worth doing today.
Texas licenses electricians through the Texas Department of Licensing and Regulation (TDLR):
Verify at the TDLR lookup. The City of Dallas requires permits for new circuits, panel replacement, service changes, generators and solar, and the inspection is your independent verification of the work.
Oncor is the transmission and distribution utility for most of the Dallas area, and any service upgrade or meter relocation requires coordination with them. That coordination frequently takes longer than the electrical work itself, so build it into your schedule.
Dallas summers impose a heavy cooling load for five to six months.
Common capacity findings:
Ask for a load calculation before assuming a service upgrade. In many homes the specific circuit is the problem and the service is fine.

North Texas gets severe thunderstorms, hail, tornadoes and, as February 2021 demonstrated, occasional extended winter grid failures.
