Wire Your New Build or Renovation Correctly From the Start

New Construction and Remodel Electrical Services in Missoula for meeting current code requirements and supporting modern electrical loads

Edison Electric provides electrical design, rough-in, and finish work for new construction projects and whole-home remodels, ensuring that your wiring infrastructure supports the circuits you need now and the capacity you will add later. Whether you are building a custom home on a sloped lot south of town or opening walls to reconfigure a kitchen and add a primary suite, you need an electrician who understands load calculations, panel sizing, and the National Electrical Code amendments adopted by the city and county. The work begins with a plan review to determine service entrance location, panel capacity, and circuit distribution, then moves through rough-in installation before drywall and final device installation after surfaces are finished.


New construction electrical work includes running conduit and cable through framing, installing junction boxes at fixture and device locations, pulling wire to the main panel, and labeling circuits for future reference. For remodels, the electrician must work around existing wiring, determine whether the current panel can handle additional circuits, and decide whether to fish wire through closed walls or open sections for access. Missoula's inspection process requires rough-in approval before insulation and final inspection before occupancy, so scheduling coordination with other trades and the building department becomes part of the project timeline.



If you are planning a build or a major remodel and need electrical design or installation that passes inspection on the first visit, contact Edison Electric to review your project scope and timeline.

How Electrical Work Integrates With Construction Phases


Your electrician coordinates with framers, plumbers, HVAC contractors, and insulation crews to ensure that boxes and cables are placed before walls close and that penetrations for service entrance conduit and exterior fixtures happen at the correct stage. During rough-in, the electrician installs boxes for outlets, switches, and ceiling fixtures, runs cable between boxes and the panel, and marks each circuit at the breaker with a description of what it serves. This stage requires precision because once drywall is hung, access to framing cavities is lost.



After walls are closed and finished, you will see outlets and switches installed at the planned locations, light fixtures mounted and connected, and a labeled breaker panel that shows which circuit controls each area of the home. Edison Electric ensures that arc fault circuit interrupters are installed on bedroom circuits, ground fault protection is in place for bathrooms and kitchens, and tamper-resistant receptacles are used in areas accessible to children, all of which are required under current code.


The scope does not include running low-voltage cabling for data or audio systems unless specifically added to the contract, and it does not cover troubleshooting or repair of damage caused by other trades after rough-in inspection is complete. The electrician works from approved plans and change orders, so any modifications to fixture locations or circuit counts must be documented before installation begins.


What to Know Before Starting Your Electrical Installation

Builders and homeowners often have questions about panel sizing, circuit planning, and how to prepare for future electrical needs without overbuilding the initial system.

  • What size service entrance do you need for a new home?

    Most new single-family homes in Missoula are wired with a two-hundred-amp service, which provides headroom for electric vehicle charging, heat pumps, and multiple high-draw appliances without requiring a panel upgrade later.

  • How does the electrician coordinate with other trades during rough-in?

    The electrician schedules installation after framing and before insulation, ensuring that boxes are mounted to studs and cables are secured to framing members without conflicting with plumbing or HVAC ductwork.

  • Why does rough-in inspection happen before drywall is installed?

    The inspector needs to see that cables are properly secured, boxes are correctly mounted, and circuits are wired according to the approved plan, all of which become inaccessible once walls are closed.

  • When should you add dedicated circuits during a remodel?

    Any time you are adding a kitchen island with an induction cooktop, installing a home office with multiple monitors and printers, or converting a garage to conditioned space, dedicated circuits prevent overloading existing wiring and reduce nuisance breaker trips.

  • What happens if the existing panel cannot support additional circuits for a remodel?

    The electrician will recommend a panel upgrade or subpanel installation to provide the necessary capacity, and that work must be completed and inspected before new circuits are connected.

Edison Electric works with homeowners, builders, and architects to develop electrical plans that meet code requirements and support the way you intend to use your space. Schedule a consultation to discuss your project timeline and ensure that electrical work is sequenced correctly with other construction activities.
