Our Process

HOW IT WORKS

01

Plan Review

02

Permit & Rough-In

We pull permits, coordinate with the county, and complete rough-in wiring before drywall — all to code.

03

Rough-In Inspection

We schedule and pass the rough-in inspection, giving you documented approval to proceed with drywall and finishing.

04

Finish & Final

We install all devices, fixtures, and panels, then pass the final inspection and issue your underwriting certificate.

The Details

RENOVATIONS & ADDITIONS

Home additions, kitchen renovations, bathroom remodels, and basement finishing all require electrical work that ties into your existing system. We assess your current panel capacity, determine what new circuits are needed, and integrate new wiring cleanly into your existing home.

We also handle dedicated circuits for new appliances, EV chargers, home offices, and HVAC equipment as part of renovation projects. If your renovation reveals outdated or unsafe wiring, we'll identify it and provide options.

Every renovation project is permitted and inspected as required. Unpermitted electrical work creates problems at resale and can void your homeowner's insurance. We protect you by doing it right from the start.
