Electrical Wiring & Rewiring in Boise, ID
Safeguard your home with master-level wiring and rewiring services. From historic knob-and-tube removal in the North End to aluminum wiring fixes and new dedicated appliance circuits across Ada County.
Signs Your Boise Home Needs Electrical Rewiring
Outdated or deteriorating electrical conductors are the leading cause of residential electrical fires in Ada County. Watch for these critical indicators that your home wiring requires professional evaluation.
Insurance Company Rewiring Deadlines?
Major homeowners insurance carriers in Idaho are increasingly refusing to write or renew policies for homes with ungrounded knob-and-tube or cloth-sheathed wiring. Connect with our certified electricians today to inspect and certify your electrical system before coverage lapses.
Discolored Wall Plates
Brown scorch marks or warm switch plates indicate arcing wires behind the wall, creating continuous thermal buildup that can ignite wall framing insulation.
Two-Prong Ungrounded Outlets
Two-slot receptacles lack an equipment grounding conductor, leaving your family and expensive electronics vulnerable to severe shock and catastrophic surge damage.
Frequent Breaker Trips & Dimmers
When running high-draw appliances like microwaves, hairdryers, or space heaters causes lights to dim or breakers to pop, your branch circuits are dangerously overloaded.
Flickering Throughout The House
Persistent light fluctuations across multiple rooms point to deteriorated shared neutral lines or frayed feeder conductors that require immediate tracing and repair.
Professional Electrical Wiring Services in Boise, ID
From historic North End bungalows to sprawling suburban homes in Meridian and Eagle, our contractors provide code-compliant wiring customized for your home.
1. Whole-Home Copper Rewiring & Modernization
Many Boise homes built decades ago were wired for modest electrical consumption—a refrigerator, basic lighting, and a radio. Modern households run computers, multiple 4K televisions, high-tonnage HVAC systems, and induction ranges that quickly overload vintage circuits.
A whole-home rewiring replaces brittle, ungrounded conductors with modern non-metallic (NM-B) copper wiring, dedicated neutrals, and proper equipment grounding to every junction box, outlet, and switch in the residence.
- Complete extraction or safe decommissioning of obsolete wiring
- High-grade 12 AWG and 14 AWG solid copper conductor installation
- Equipping every habitable room with code-mandated AFCI protection
- Neat, surgical cable pulling minimizing wall and ceiling patchwork
2. Historic Knob-and-Tube Wiring Remediation
Boise's charming historic neighborhoods, such as the North End, East End, and Warm Springs Avenue, are filled with architectural character—and aging knob-and-tube wiring. This early 20th-century system lacks a ground wire and utilizes rubberized cotton insulation that dries out and crumbles over time.
When attic thermal insulation is blown over knob-and-tube wiring, it traps heat, transforming the circuit into a hidden fire danger. Our licensed contractors specialize in historic preservation rewiring, protecting your historic woodwork, plaster walls, and molding while bringing power up to 21st-century standards.
- Thorough mapping and electrical insulation testing of vintage circuits
- Safe removal from attics before energy-efficiency insulation upgrades
- Installation of grounded three-prong receptacles throughout historic rooms
- Compliance certifications provided for home insurance underwriting
3. Aluminum Wiring Remediation & COPALUM Pigtailing
Homes built in Boise between roughly 1965 and 1973 often feature aluminum branch wiring. Aluminum expands at a much faster rate than copper when carrying electrical current, creating loose connections at switches and receptacles where dangerous electrical arcing can occur.
Rather than an invasive, costly full teardown, electricians use Consumer Product Safety Commission (CPSC) approved methods, including cold-welded COPALUM crimping and AlumiConn lug connectors with anti-oxidant paste to safely link copper pigtails to existing aluminum wires.
- Full home device inspection for signs of aluminum thermal damage
- COPALUM or heavy-duty AlumiConn multi-port lug installation
- Replacement of standard receptacles with aluminum-rated CO/ALR switches
- Elimination of loose connections and fire hazard points at every junction

Call (208) 990-00294. Dedicated Circuits, Basements & ADU Additions
Modern high-draw appliances demand their own isolated branch circuit directly from your breaker panel. Sharing lines with kitchen appliances, garage shop equipment, or heat pumps causes chronic overloads and equipment strain.
Whether you are finishing an unfinished basement in Meridian, building an Accessory Dwelling Unit (ADU) in Boise, or installing a high-end gourmet kitchen, our electricians run dedicated 120V and 240V circuits designed to handle continuous peak loads safely.
- 240V lines for induction cooktops, ovens, hot tubs, and dryer receptacles
- Subpanel installation for detached garages, backyard workshops, and ADUs
- Dedicated lines for central air conditioners, heat pumps, and tankless water heaters
- Complete rough-in and trim-out wiring for home additions and remodels

Common Questions About Boise Electrical Wiring
Clear answers to help you navigate residential rewiring, historic home codes, and safety in Ada County.
Homes constructed in Boise before 1950—common in the North End, East End, and parts of the Boise Bench—frequently contain knob-and-tube wiring. Look in your attic, unfinished basement, or crawl space for white ceramic spool knobs anchoring wires to joists and ceramic tubes passing through lumber. If insulation has been blown over these wires, it creates a severe fire hazard as knob-and-tube requires open air dissipation.
Whole-home rewiring in Boise typically ranges from $4,000 to $12,000+ depending on home square footage, single vs. multi-story layout, wall composition (lathe and plaster vs. drywall), and crawlspace accessibility. Partial rewiring or adding dedicated lines typically costs between $500 and $2,000.
No. Experienced electricians utilize surgical fishing techniques, flexible drill bits, and access points through attics, basements, and crawlspaces to route modern NM-B Romex copper cabling with minimal cuts into plaster or drywall. Any small access holes required are kept neat and manageable.
Homes built in the Boise area between 1965 and 1973 often used single-strand aluminum wiring. Aluminum expands and contracts under electrical loads much more than copper, causing loose terminal connections, oxidation, and sparking. Licensed electricians safely remediate aluminum wiring using specialized COPALUM crimping or AlumiConn terminal connectors approved by the Consumer Product Safety Commission.
Yes. Adding new branch circuits, altering existing wiring, or undertaking full-home rewiring requires an electrical permit and inspection from the City of Boise Planning & Development Services or the Idaho Division of Building Safety to verify compliance with the National Electrical Code (NEC).
A complete whole-house rewiring project on an average 1,500 to 2,500 square-foot Boise residence generally takes 3 to 7 working days. Technicians typically keep power functional to essential circuits overnight so you can remain comfortable in your home throughout the process.
