The cost to rewire a house is not reliably priced by square foot; electricians price it by scope, access, and required upgrades. The biggest cost driver is how much of the wiring must be replaced and whether walls and ceilings must be opened versus accessed from attics, crawlspaces, or basements.
A full estimate typically accounts for circuit count, device replacements (outlets, switches, lighting), any panel/service upgrade, and permitting/inspection needs. Our team also coordinates utility and inspection requirements as part of a whole-home rewire, and we install dedicated circuits for new loads when needed. We serve homes in the greater San Antonio area and regularly handle Saint Hedwig projects. Financing is available, and you can receive a free whole-home surge protector with any panel or full service upgrade.
Expect your estimate to reflect these factors:
- Access conditions and patching needs after fishing or opening walls
- Need to upgrade the main panel or service amperage
- Number of new dedicated circuits for appliances, EVs, or additions
- Project phasing to keep an occupied home powered during work
