Upgrading Old Wiring
We disconnect existing wiring and snake in new wiring through the old walls. We use standard, top-quality products that are known throughout the field. We usually come in and do a consultation and prepare an estimate.  We send you an estimate via e-mail and schedule an appointment. Most rewire jobs take about 1½ weeks per floor.

Service Upgrades
This process is to remove the old service equipment. We install new service equipment and upgrade wires to a larger size and then remove the circuit breaker panel and install a new circuit breaker panel. A service upgrade normally takes only about 1 day to complete.

Adding New Outlets
This process entails cutting access to the holes to snake new wires to the holes. We then install new wires in the walls. New covers, new outlets, a new box, and new wires are included in the price. We use the outlet covers that you choose.


Trust our experts to upgrade the electrical wiring in your home.
