Electrician FAQ for 78242
How much does an electrician cost per hour?
Licensed residential electricians generally charge in the $50 to $150 per hour range in 2026, plus a service call fee of roughly $75 to $200. Most companies now price common jobs flat-rate rather than hourly, which means the number you are quoted is the number you pay if the scope does not change.
Is 24/7 emergency service available for 78242?
Emergency requests are taken around the clock. Central time applies locally, and after-hours availability depends on the contractor on duty — genuine emergencies such as burning smells, smoke, sparks or water contacting live wiring are prioritised over routine work.
Do you handle both homes and small businesses?
Most local electrical contractors take residential work and light commercial work such as retail, restaurant and office premises, including three-phase distribution, lighting retrofits and dedicated equipment circuits. Larger commercial projects are quoted from a site survey.
