What should I do today or this week?
Do not let an unlicensed handyman open walls or panels. Call Austin Volts at (737) 367-2100 to get a referral to a licensed, insured local pro. If you notice warm outlets, flickering lights, or burning smells, turn off the affected circuit until someone qualified inspects it.
What should I check when hiring or switching electricians?
Texas requires anyone performing electrical work to be licensed, and electrical contractors must work through a licensed electrical contractor. Contractors must carry at least $300,000 per occurrence and $600,000 aggregate liability coverage. Ask the pro for proof of licence and insurance before work starts.
Who needs to be on site for electrical work in Austin?
In Austin, at least one licensed journeyman electrician, master electrician, or residential wireman must be present on-site to supervise electrical work. Electrical permits are required before installation, alteration, or replacement begins, and the applicant must be an electrical contractor. Licensees must show their license and picture ID when asked.
Why do old homes often need more than a simple rewire?
Replacing knob-and-tube wiring often includes adding outlets and updating the service panel to meet current code. Rewiring permits typically cost about $250 to $900, and knob-and-tube work may need one or more permits depending on scope. Permit rules and fees can differ between cities and the state.
What to do next
- Ask the pro for their Texas electrical license number and verify it on the TDLR license lookup before work starts.
- Confirm the contractor employs a licensed Master Electrician and carries at least $300,000 per occurrence and $600,000 aggregate liability coverage.
- Request a written quote that lists whether an electrical permit is required and who pulls it, since Austin permit rules can differ from state rules.
- Ask how the job will be supervised on site and confirm a licensed journeyman, master electrician, or residential wireman will be present.
