How Long Does Electrical Work Take? Realistic Timelines for 12 Common Jobs

"How long will you be here?" is the second most common question we get, right after price. Here are honest, realistic timelines based on actual DFW jobs — not the "under an hour!" fantasy pricing you see online.

Quick Reference: Time on Site

| Job | Time on Site | Power Off? |

|---|---|---|

| Replace outlet or switch | 20–40 min | Just that circuit |

| Install GFCI outlet | 30–50 min | Just that circuit |

| Ceiling fan (existing box) | 45–75 min | Just that circuit |

| Ceiling fan (new location) | 2–4 hrs | Just that circuit |

| Add dedicated 20A circuit | 2–5 hrs | Just the panel briefly |

| NEMA 14-50 EV outlet | 3–6 hrs | Panel off ~15 min |

| Hardwired Level 2 EV charger | 4–7 hrs | Panel off ~15 min |

| Whole-home surge protector | 45–90 min | Whole house ~30 min |

| 100A → 200A panel upgrade | 6–8 hrs on-site (1 day) | Whole house 6–8 hrs |

| Full service change (mast + meter) | 8–10 hrs on-site (1 day) | Whole house 8–10 hrs |

| Generac 22–24kW install | 2–3 days total | Whole house ~1 hr total |

| Whole-home rewire | 5–10 business days | Rolling by room |

Why Small Jobs Sometimes Take Longer Than Big Ones

An "easy" ceiling fan can turn into 4 hours when we open a box and find:

No fan-rated support (needs a new brace box from the attic)

Aluminum branch wiring (needs CO/ALR-rated connectors — an extra $45 in materials and 20 minutes)

3-way switch legs someone rewired backwards (30 min of tracing)

We tell you *at the door* if anything we see will push the estimate. No surprise line items at the end.

Permit Timeline vs Work Timeline

For panel upgrades, service changes, EV chargers, and generators in DFW, add:

Permit pull: 1–3 business days (we handle it — you don't need to)

Oncor disconnect scheduling: 3–7 business days

City inspection after work: same day for Burleson, 24–48 hrs for Fort Worth

Oncor reconnect: same evening as work

So a "1-day install" panel upgrade is usually 7–10 calendar days start to finish from the day you sign.

Utility service upgrade with new meter base being installed

What Delays a Job

HOA architectural approval (generator installs — add 2–4 weeks in Mansfield, Aledo, some Fort Worth subdivisions)

Backordered panels — Square D 200A is usually in stock; some Eaton loadcenters run 2–3 week leads

Weather (Oncor won't work above certain wind speeds; we can't safely work on roofs in rain)

Discovering aluminum wiring that requires additional pigtailing throughout the home

What Speeds a Job Up

Clear access to the panel (move stuff *before* we arrive)

Someone home who can approve small change orders on the spot

Existing straight-shot conduit for EV chargers vs having to fish walls

Booking non-emergency work Tuesday–Thursday (Mondays and Fridays fill first)

Same-Day vs Scheduled

Same-day emergency (dead panel, burning smell, sparks): 60–90 min response, 24/7. Rates about 1.5x standard.

Same-day non-emergency (outlet, breaker replacement): usually possible if you call before 11 AM.

Scheduled: 3–7 business days out for most residential work in DFW.
