House rewiring cost per square foot is not a fixed rate and is confirmed after an on-site inspection by Elmer's Home Services. Costs hinge on home age, layout, and how much new electrical infrastructure the project requires. Square-foot math breaks down fast in older homes with plaster walls or mixed circuits. For projects in the Olmos Park area, we coordinate permitting, inspections, and utility requirements so the estimate reflects the actual scope.
Key factors that change price:
- Need for a panel/service upgrade (often moving from 100 to 200 amps or higher).
- Number of new or dedicated circuits for major appliances.
- Access conditions for walls, attic, and crawl spaces, including patching needs.
- Added devices and fixtures like outlets, switches, lighting, ceiling fans, or prep for EV chargers and generators.
Current special: Free Surge Protector With Purchase of Any Panel or Full Electrical Service Upgrade ($795 Value).
Have a licensed electrician evaluate the panel, circuits, and access points before setting a budget.
