What Home Rewiring Actually Involves

If your house has cloth-wrapped wiring, aluminum branch circuits, or a panel that trips on a regular Tuesday afternoon, you're not dealing with a nuisance. You're dealing with a fire and code-compliance risk that gets worse the longer it sits. Home rewiring is the process of replacing the conductors, outlets, switches, and related components throughout the house so the electrical system meets current NEC standards. All Electric has completed this work across hundreds of Front Range homes. CO License #ME.0600978, fully insured, and backed by a 1-year labor warranty. Call (720) 951-4619 to schedule an inspection.

The scope drives the cost more than anything else. A partial rewire targeting one circuit is a fundamentally different job from a full house rewire on a three-story home with finished walls and no attic access. Age of the home, number of circuits, current wiring material (knob-and-tube, aluminum, or old two-wire cloth), and how accessible the wall cavities are all move the number. Permit requirements from your local jurisdiction also factor in, and we handle the permit process as part of the job. Every job is different, contact All Electric for an accurate estimate.

Signs Your Wiring Needs to Be Replaced

  1. Cloth or Knob-and-Tube Wiring

    Homes built before 1950 frequently have knob-and-tube or cloth-wrapped wiring. Both lack a ground conductor, and the insulation degrades over decades. Most insurers won't write a new policy on a home that still carries it. We've written a deeper breakdown in our article on whether to replace aluminum wiring. The risk calculus is similar.

  2. Aluminum Branch Circuit Wiring

    Aluminum wiring installed in the late 1960s and 1970s expands and contracts differently than copper, which loosens connections at outlets and switches over time. That's a heat and arc-fault risk. It doesn't always mean a full rewire, sometimes pigtailing with CO/ALR connectors is the right fix, but a licensed inspection will tell you which applies.

  3. Frequent Breaker Trips

    A breaker that trips regularly is doing its job, but the underlying cause matters. If you're overloading a circuit, you may need additional dedicated circuits rather than a full rewire. If the wiring itself is degraded, the breaker can't protect against a smoldering connection inside the wall. Our circuit breaker service covers both scenarios.

  4. Outlets Without Ground Slots

    Two-prong ungrounded outlets throughout the home indicate older two-wire wiring that predates modern grounding requirements. Running three-wire circuits back to the panel is the code-compliant fix, GFCI substitution is permitted in some cases but doesn't solve the underlying wiring age issue.

  5. Discolored or Warm Switch Plates

    Warm outlets or switches, scorch marks, or a faint burning smell around devices are the clearest sign of a connection that's arcing or overheating inside the wall. Don't reset the breaker and move on. Turn off the circuit and call.

  6. Failed Home Inspection or Insurance Renewal

    Pre-sale electrical inspections and insurance underwriting reviews regularly flag old wiring systems. If your inspection report cited code violations, a licensed rewire with a city permit and final inspection is what clears it, not a patch.

Our Process

How the Rewiring Process Works

  1. Step 1: Inspection and Scope

    First, we inspect the existing wiring system, outlets, switches, panel, and accessible wiring runs, to document what's there and what code requires. This gives us the information to plan the work accurately before anything is opened up.

  2. Step 2: Removal and Rough-In

    Once the plan is in place, old wiring is removed and new conductors are pulled through walls, ceilings, and the attic where accessible. We coordinate the permit and schedule the rough-in inspection before walls are closed.

  3. Step 3: Devices, Panel, and Final Inspection

    After rough-in approval, we install outlets, switches, fixtures, and any upgraded panel work, then complete the final inspection with the authority having jurisdiction. The system isn't done until it passes.

Scope of Work

What All Electric Handles on a Rewiring Job

A full rewire isn't just pulling wire. Here's what the job covers from start to final sign-off.

  1. 01

    Electrical inspection and code review

    We document the existing system before any work starts, checking wiring material, grounding, overcurrent protection, and GFCI/AFCI coverage against current code.

  2. 02

    Permit application and jurisdiction coordination

    We pull the permit, coordinate the rough-in and final inspections, and make sure the city signs off before you move back in.

  3. 03

    Old wiring removal

    Knob-and-tube, aluminum branch circuits, or deteriorated cloth wiring is removed safely with proper safety precautions, no cutting corners to save wall repair time.

  4. 04

    New wiring installation to NEC and local code

    We run copper conductors sized for each circuit's load, with proper grounding throughout. Electrical remodeling work done at the same time can be integrated into the same permit.

What Drives the Cost of Rewiring a House

frequent breaker trips work, professional service in Denver, CO
Honestly, the question we get most often is some version of 'how much does it cost?' The honest answer: it depends on factors that vary substantially house to house. A smaller home with an open attic and unfinished basement walls is a very different job from a finished two-story with no attic access and plaster walls. The main cost drivers are square footage and number of circuits, the type of existing wiring and whether it's hazardous to handle, wall accessibility, open framing is faster than cutting through drywall or plaster, the panel's current condition and whether it needs upgrading alongside the wiring, and local permit fees and inspection scheduling. We've broken down more detail on how to save on renovation electrical work in this article. Every job is different, contact All Electric for an accurate estimate. Financing is available for larger rewiring projects, and we're happy to walk through what's involved before you commit to anything.

Home Rewiring FAQs

Not answered here? Call (720) 951-4619 and ask the electrician.

How do licensed electricians approach wiring a home during a full rewire?
We start with a circuit-by-circuit inspection to map what's existing and what code requires. Then we pull the permit, remove the old conductors, rough in the new copper wiring sized to each circuit's load, and schedule the rough-in inspection before closing walls. After inspection approval, devices and fixtures are installed and a final inspection closes the permit. We don't skip the inspection steps. A rewire without a final sign-off isn't done.
Does a home rewire require opening walls throughout the house?
Not always throughout, but realistically in most areas. Homes with accessible attics and unfinished basements can often have wire pulled with minimal wall cuts. Finished walls on both sides typically require strategic cuts at each device location. We're direct about what access the job needs before we start, no surprises mid-project.
What's the difference between a full rewire and replacing just a few circuits?
A partial rewire targets specific problem circuits, an overloaded kitchen circuit, a deteriorated basement run, or a few aluminum branch circuits in a bedroom wing. A full rewire replaces every branch circuit in the home. If a whole-house inspection reveals that more than 40-50 percent of the circuits are deficient, a full rewire is usually more cost-effective than chasing individual problems. We'll tell you which applies honestly after the inspection.
Will my home need a panel upgrade as part of a rewire?
Often, yes. A full rewire adds circuits and frequently exposes the fact that the existing panel is undersized, outdated, or has a known safety issue, Federal Pacific Stab-Lok panels, for example, carry documented breaker-failure risks. If the panel can't safely support the new wiring, we address it as part of the same project. A rewired house feeding through a compromised panel isn't a safe result.
How long does a home rewiring project typically take?
A smaller home with accessible walls can be roughed in within two to three days. A larger home with finished walls, multiple stories, and no attic access can run a week or more. The permit inspection timeline adds variable time depending on the jurisdiction. We give you a realistic schedule before work starts, not an optimistic one we can't hold.
Can I live in the house while it's being rewired?
For partial rewires, typically yes, we work circuit by circuit and restore power to uninvolved areas. For a full rewire, there will be extended periods without power to large portions of the home. We discuss this during the scoping conversation and flag it clearly, so you can make arrangements if needed rather than finding out mid-project.
Is a permit required for a home rewire in Colorado?
Yes. Any work that involves adding or replacing wiring, outlets, or panel components requires a permit and inspection from your local authority having jurisdiction. We pull the permit as part of the job and coordinate both the rough-in and final inspections. Work done without a permit can't be signed off and creates problems at resale.
