Wiring replacement
Whole-Home Rewiring in Centennial, CO
Aluminium branch circuits, cloth-insulated conductors and ungrounded two-prong wiring replaced in phases that keep the house usable. Centennial, Littleton and the older streets around Southglenn.
When the Wiring Itself Is the Problem
Rewiring is the job nobody plans for and most people discover. It usually surfaces during a remodel, at a home inspection, or when an insurance carrier asks a question the homeowner cannot answer.
Centennial Electric handles whole-home rewiring across Centennial and the surrounding south metro, and in this part of Arapahoe County three situations account for most of the work. Aluminium branch wiring, installed widely in the mid-1970s, expands and contracts at terminations until the connection loosens and heats. Ungrounded two-wire circuits in 1960s ranches leave no equipment ground, which rules out safe grounded receptacles and surge protection. And cloth-insulated or early knob-and-tube wiring in the oldest stock has simply reached the end of a long life.
A full rewire is a significant project, so the first thing we establish is whether you actually need one. Frequently the honest answer is a partial rewire of specific circuits, which costs a fraction and solves the real risk.
What a Rewire Covers
Scope is agreed before anything opens, and the list below is what a full project includes.
- 1Full wiring assessment with documentationWe open representative devices and boxes across the house, identify every conductor type present and photograph what we find. You get a written picture of the house rather than a verdict.
- 2Partial or full scope, honestly recommendedIf the hazard is concentrated in the kitchen, the bathrooms and the garage, we will tell you that instead of quoting every room.
- 3New branch circuits in modern cableCopper conductors in current-code cable, sized to the load, with a dedicated equipment ground throughout.
- 4Aluminium termination remediationWhere a full replacement is not justified, approved connectors correctly applied at every aluminium termination, which is the accepted remedy and dramatically cheaper.
- 5Grounded receptacles throughoutTwo-prong devices replaced with grounded receptacles once a genuine equipment ground exists, with ground-fault and arc-fault protection where the current code requires it.
- 6Dedicated circuits for modern loadsKitchen small-appliance circuits, laundry, bathroom, microwave, range and HVAC separated onto their own runs as the code intends.
- 7Panel work coordinated with the rewireNew circuits need somewhere to land. If the panel is full or outdated, we sequence the service change with the rewiring so the work happens once.
- 8Routing planned to minimise drywall damageAttics, crawl spaces, closet chases and basement joist bays carry most of a rewire. We fish wherever fishing is possible.
- 9Patching to a paint-ready finishEvery opening we make is closed, taped, textured and sanded ready for your painter.
- 10Permitted and inspected in stagesRough inspection before the walls close, final inspection at completion, both filed under one permit and both attended by us.
How a Rewire Is Run
Assessment and scope
A licensed electrician spends real time in the house, opening boxes, checking the attic and crawl space, and mapping what is actually installed. From that we build a scope with phases, a sequence and a written price for each. You see where the money goes and why, and you decide how much of it to do now.
Phased installation
We work one zone at a time so you are never without power to the whole house. New circuits are run and terminated, the rough inspection happens before anything closes, and then openings are patched. A phased rewire of an average Centennial home runs over several working days per phase, scheduled around your household rather than ours.
Final inspection and handover
The jurisdiction inspects the finished work, we meet the inspector and resolve anything raised. Then we label the panel directory circuit by circuit, hand over the permit record and the warranty, and walk you through what changed and what, if anything, remains for a later phase.
Why Centennial Electric for a Rewire
We quote the rewire you need, not the one that pays best
A whole-house rewire is one of the largest residential electrical jobs there is. If your risk is concentrated in a dozen terminations, we would rather remediate those and keep you as a customer than sell you a project you did not need.
Phasing keeps the house livable
Nobody wants to move out. We sequence zones so the kitchen and the bedrooms are never dark at the same time, and we restore power to finished zones before moving on.
Drywall is treated as part of the job
Rewiring reputations are made and lost on patching. We plan routes to minimise openings and we close every one of them to a finish your painter can work with, rather than leaving a line of squares behind a promise.

Find Out What Is Actually in Your Walls
If an inspector wrote "aluminium branch wiring" on a report, or every outlet in the house has two slots and no ground, the first step is an assessment rather than a quote. We will tell you what is there, what the real risk is, and what the smallest effective fix looks like. Serving Centennial, Littleton, Englewood, Greenwood Village and the surrounding south metro.
