Best Electrical in Arlington, TX — 36 Vetted Contractors

Yes, without exception. The City of Arlington Development Services requires a permit for any service upgrade or panel replacement. The permit triggers an inspection by a City of Arlington electrical inspector after the work is complete. Your licensed electrical contractor should pull this permit — not you. Skipping it can void your homeowner's insurance coverage for related claims and will surface as an unpermitted improvement during a home sale. Budget roughly $75–$150 for the permit fee, which most contractors include in their quote.

Go to license.tdlr.texas.gov and search by the contractor's name or license number. Per the Texas Department of Licensing and Regulation, you want to confirm they hold an active Electrical Contractor license (not just a Journeyman license — that's an individual credential, not a business license). The search is free and takes about 30 seconds. If a contractor can't provide their TDLR number before you sign a contract, don't sign.

Possibly. Homes from that era in Arlington frequently have 100-amp service, which is undersized for modern loads — especially if you're adding an EV charger, heat pump, or home office equipment. More urgently, some 1980s homes still have Federal Pacific Stab-Lok panels, which have a documented history of breaker failure and fire risk. Have a licensed electrician inspect your panel. If it's a Federal Pacific or Zinsco brand, replacement is strongly recommended regardless of apparent condition.

In May, before the summer surge, most licensed Arlington electricians can schedule a panel upgrade within 1–2 weeks of signing a contract. The physical work typically takes one full day (6–8 hours). Add 3–7 business days for the City of Arlington inspection to be scheduled after completion. Total timeline from first call to final inspection: roughly 2–3 weeks in May. Expect that to stretch to 4–6 weeks if you wait until July or August.

Based on regional pricing data for the DFW market, expect $400–$1,200 installed for a Level 2 (240V, 40–50 amp) charger in Arlington. The low end applies when your panel has capacity and the garage is close to the panel. The high end applies when you need a sub-panel, a long conduit run, or load management equipment. A permit is required. Get 2–3 quotes and confirm the permit fee is included — some contractors quote the charger installation but bill the permit separately.

Aluminum branch circuit wiring — common in homes built 1965–1973 — carries elevated fire risk if connections have loosened over time. It's not an automatic emergency, but it requires assessment by a licensed electrician. Remediation options include replacing outlets and switches with CO/ALR-rated devices or copper pigtailing at each connection point. Per the U.S. Consumer Product Safety Commission, homes with aluminum wiring are statistically more likely to have fire hazard conditions than copper-wired homes. Don't ignore it, but don't panic — get a professional assessment first.

Texas law allows homeowners to perform electrical work on their own primary residence without a TDLR license, but you must still pull the required permits from the City of Arlington and pass inspection. In practice, this is practical only for very simple work (replacing a like-for-like outlet or switch). Anything involving the panel, new circuits, or service entrance should be done by a licensed electrical contractor — the inspection failure rate for homeowner-performed panel work is high, and the liability if something goes wrong is entirely yours.

A repeatedly tripping breaker in Arlington's summer heat is usually one of three things: an overloaded circuit (too many high-draw appliances on one circuit), a failing breaker (common in panels over 20 years old), or a wiring issue creating a fault. Don't just reset it repeatedly — that's how fires start. Call a licensed electrician for a diagnostic visit. In summer, same-day service calls for this type of issue typically run $150–$300 for the diagnostic, with repair costs depending on the root cause. It's worth it.
