When this Coeur d’Alene homeowner called Mainstream Electric, Heating, Cooling & Plumbing, they were worried about aging wiring, limited power, and staying safe while updating their home. Our licensed electricians completed a full-home rewire and new service panel, carefully working around existing insulation and finishes. In just a few days with two coordinated crews, we transformed an outdated electrical system into a safer, code-compliant setup ready for everyday life and future projects.
Job Overview
- Location: Coeur d’Alene, Idaho
- Client Type: Single-family homeowner in an older home
- Scope: Full-home electrical rewire with new service panel and device upgrades
- Equipment Installed: New main electrical panel with breakers, whole-home surge protection, updated service conductors, new branch circuits, GFCI protection, dimmers, and updated outlets/switches
- Additional Work (if any): Coordinated with third-party insulation testing due to vermiculite in the structure, electrical trim-out with devices and plates
- Why It Mattered: The old system was not designed for modern electrical loads and presented safety and reliability concerns; the homeowner needed a safer, up-to-code electrical system they could depend on
What We Found
During our initial assessment, our electricians found an older electrical system that had been added onto over the years. Some circuits were heavily loaded, there were limited dedicated circuits for large appliances, and grounding and surge protection did not meet current best practices.
The home also had vermiculite insulation in areas where we needed to work. Vermiculite can sometimes be associated with asbestos, so disturbing it without proper testing and precautions is not safe. Before moving forward, the homeowner arranged for a third-party company (Quick Dry) to come out and test the insulation so we could plan the work safely and responsibly.
Overall, the existing wiring and panel were functioning but were not set up for the homeowner’s current and future electrical needs. Between increased plug-in devices, kitchen appliances, and plans for ongoing improvements, the home needed a full rewire and electrical panel upgrade to bring everything up to modern standards.
The Solution
With the permit in place and insulation tested, our team scheduled a four-day project with two crews to keep the job moving quickly and safely.
- Prepared the home: We set up safe work areas, protected floors and finishes, and shut off power where needed so we could work cleanly and safely.
- Rewired and upgraded the service: Our electricians removed outdated wiring where required and pulled in new copper conductors for the home’s branch circuits. We installed a new main electrical panel, updated service conductors, and added whole-home surge protection to better handle today’s electrical loads.
- Added circuits and new devices: We provided dedicated circuits for large appliances like the range and oven, rebalanced loads across breakers, and installed new outlets, switches, dimmers, plates, and GFCI protection in required areas.
- Tested and verified everything: Once installation was complete, we tested every circuit for correct voltage, grounding, and breaker operation, confirmed all devices worked properly, and walked the homeowner through the new panel labeling and system layout.

The Results
By the end of the project, this Coeur d’Alene home had a modern, code-compliant electrical system designed for today’s power demands. The new panel and service conductors provide a strong, reliable backbone for the entire house, while the rebalanced circuits reduce the risk of tripped breakers and hot spots.
With GFCI protection in key areas, improved grounding, and whole-home surge protection, the homeowner now has a safer system that better protects their family, appliances, and electronics. Perhaps most importantly, they can move forward with confidence on future upgrades knowing their electrical system is built to handle it.
