Three Rewire Services
Whole-Home Rewiring, Knob-and-Tube, and Aluminum Wiring in Denver
Three rewire scopes covering the most common Denver residential wiring problems. All three include permits, city inspection, drywall patching, and insurance documentation.
Whole-Home Rewiring
Complete branch circuit replacement
Full replacement of all branch wiring throughout the home with modern grounded copper Romex (NM-B). The right scope for homes with mixed wiring, code violations, or planned major renovations. Includes a panel upgrade if the existing service is undersized.
Knob-and-Tube Replacement
Pre-1950 wiring removal
Knob-and-tube wiring is an early-twentieth-century method with no ground wire, ceramic insulators, and cloth-covered conductors. Insurance carriers increasingly require replacement before issuing or renewing policies. We replace knob-and-tube throughout the home with modern grounded Romex.
Aluminum Wiring Replacement
Copper retrofit and full rewires
Solid aluminum branch wiring was used in residential construction during a copper shortage from 1965 to 1973. Aluminum expands and contracts at outlets and switches, loosening connections and creating a fire risk recognized by the Consumer Product Safety Commission. We replace aluminum branch wiring with copper.

Signs Your Denver Home Needs Rewiring
If you recognize three or more of these warning signs, schedule a wiring inspection. Most show up before a major electrical failure or fire.
Identify Your Wiring
Knob-and-Tube vs Aluminum vs Modern Romex
Three eras of residential wiring used in Denver-area homes. Knowing which one you have determines the rewire scope and urgency.
Knob-and-Tube
Single conductors routed separately through ceramic knobs and tubes. Cloth or rubber insulation, no ground wire. Visible in unfinished attics and basements as bare ceramic insulators with cloth-wrapped wires running through joists.
Aluminum Branch
Solid aluminum conductors used during a 1965 to 1973 copper shortage. Silver-colored wire visible inside outlets. Aluminum expansion and contraction loosens screw connections over many years, creating heat and a recognized fire hazard.
Modern Romex (NM-B)
Copper conductors in non-metallic sheathing with a dedicated ground wire. Color-coded jackets identify gauge. The current National Electrical Code standard for residential branch wiring and what we install in every rewire.

What is whole-home rewiring?
Whole-home rewiring is the complete replacement of a residential property’s electrical branch wiring with modern grounded copper Romex (NM-B). The process replaces all outlets, switches, and branch circuits while bringing the service panel and grounding to current National Electrical Code standards. The Electricians is a licensed Denver electrician specializing in whole-home rewires for knob-and-tube and aluminum-wired homes throughout Centennial, Highlands Ranch, Aurora, Littleton, and the entire Front Range.
Why Denver Homes Need Rewiring
Denver’s residential housing stock spans more than 130 years of construction. Historic neighborhoods like Park Hill, Capitol Hill, Highland, Berkeley, and Washington Park contain thousands of homes built before 1950 with original knob-and-tube wiring still in place behind finished walls. Mid-century neighborhoods built between 1965 and 1973 frequently contain solid aluminum branch wiring that has loosened at connection points after years of thermal expansion and contraction.
Modern household electrical demand has roughly tripled since these homes were built. Central air, induction cooking, electric vehicle charging, home offices, and dozens of always-on smart devices stress wiring that was sized for a 1940s or 1960s lifestyle. Insurance carriers have noticed. More major insurers now require knob-and-tube or aluminum wiring upgrades before issuing or renewing homeowners policies. Our licensed Denver electricians handle the full rewire scope from initial inspection through final permit closeout.
How to Tell If Your Home Needs Rewiring
Most homes signal rewiring needs long before a major failure. Frequent breaker trips under normal load, outlets warm to the touch, lights that dim when major appliances start, two-prong ungrounded outlets throughout the home, and visible knob-and-tube or aluminum wiring are the most reliable indicators. The strongest single signal is the smell of burning plastic anywhere near outlets, switches, or the service panel. Any burning odor is an emergency. Stop using affected circuits and call our 24-hour emergency electricians immediately.
A second strong signal is a request letter from your insurance carrier. Carriers increasingly mail policy holders requiring an electrical inspection and upgrade before renewal. If you have received one, document the request and schedule a wiring survey within the timeframe specified. Most carriers accept a licensed-electrician inspection report plus a rewire scope quote as evidence of compliance progress.
Knob-and-Tube, Aluminum, and Modern Romex Compared
Knob-and-tube wiring, used from roughly 1880 through 1950, routes single insulated conductors separately through ceramic knobs and tubes. The system has no ground wire and the cloth or rubber insulation degrades unpredictably as the wiring ages. Modern building codes do not permit new knob-and-tube installations, and most insurance carriers treat existing knob-and-tube as a known risk. Replacement requires running new branch circuits with proper grounding throughout the home.
Aluminum branch wiring saw widespread residential use from 1965 to 1973 during a copper supply shortage. Solid aluminum conductors expand and contract more than copper, gradually loosening screw connections at outlets, switches, and panel terminations. Loose connections heat up under load and have been linked to residential fires by the Consumer Product Safety Commission. Remediation options include full copper rewire or partial mitigation using CO/ALR-rated devices and AlumiConn connectors at every termination.
Modern Romex, technically NM-B cable, is the current National Electrical Code standard for residential branch wiring. Copper conductors run inside a non-metallic sheath with a dedicated ground wire. Color-coded jackets identify wire gauge at a glance. Every rewire we complete uses NM-B sized appropriately for each circuit, terminating into a properly grounded service panel that meets current panel and breaker code.
How long does whole-home rewiring take?
Most whole-home rewires take one to three weeks depending on home size, accessibility, and the extent of drywall restoration. A typical 2,000 to 3,500 square foot Denver home rewire is completed in 7 to 14 working days. The Electricians schedules rewires around your occupancy so families can typically remain in the home during the work, with electricity rotated through circuits to maintain essential power throughout each phase.
What Whole-Home Rewiring Includes
A complete rewire scope replaces every branch circuit in the home. The Electricians leaves old wiring in place where removal would cause excessive damage, abandoned in walls and disconnected at both ends. New circuits route through the same fishing paths wherever possible to minimize drywall disruption.
A typical rewire scope includes:
- All branch circuit wiring replaced with copper NM-B Romex
- Every outlet replaced with grounded receptacles, GFCI in wet locations, AFCI on bedroom and living circuits per current code
- All switches and dimmers replaced
- Service panel upgraded if undersized or outdated
- Dedicated circuits added for kitchen, laundry, and appliances per current code
- Smoke and carbon monoxide detectors hardwired and interconnected
- Permit pulled with the City and County of Denver or applicable jurisdiction
- Rough-in and final electrical inspections coordinated and passed
- Drywall patching, texture matching, and primer at every wire pull access point
- Full documentation package for insurance and resale
Permits and Code Compliance in Denver
Whole-home rewiring requires an electrical permit from the City and County of Denver or the appropriate suburban jurisdiction. Permits must be pulled by a licensed electrical contractor with active master electrician certification. The Electricians handles the application, scheduling, and inspector meetings throughout the project. Rewires must comply with the current National Electrical Code adopted by Colorado, which includes specific requirements for arc-fault and ground-fault protection by room type.
A typical rewire goes through two inspections. The rough-in inspection happens after new wiring is pulled and connected but before walls are closed back up. The final inspection happens after devices are installed, the panel is energized, and the system is tested under load. Each inspection generates a permit record that follows the home through future sales.
Insurance Implications of Knob-and-Tube and Aluminum Wiring
Major insurance carriers have tightened underwriting standards on homes with knob-and-tube or aluminum branch wiring. Some carriers will not issue new policies on properties with either wiring type without an upgrade. Others will issue policies but charge significantly higher premiums or require a remediation timeline. A few will non-renew at the end of an existing policy term.
The documentation package The Electricians provides at rewire completion is designed to satisfy carrier requirements. It includes the permit record, both inspection sign-offs, a wiring scope-of-work summary, and a licensed-contractor letter confirming the home is fully rewired to current code. Homeowners typically forward this package to their carrier and either receive policy approval, lower premiums, or both.
Cost Factors for Whole-Home Rewiring
Every rewire is quoted as a flat-rate written price after an in-home survey. The factors that drive the quote are square footage, number of circuits, accessibility through attic and basement, wall and ceiling finishes (plaster is harder to patch than drywall), whether a panel upgrade is needed, and the scope of outlet and circuit work added to meet current code. Multi-story homes, plaster walls, finished basements, and limited attic access all extend the timeline and scope.
Financing options through GreenSky are available to spread the rewire cost across monthly payments. We will walk you through the financing path during the quote review if you prefer monthly payments over a single project cost.
