Three routes, not one
Full, partial, or staged
Which applies depends on how much original wiring remains, its condition, whether grounding exists, panel and service capacity, and what you're planning to add.
If a full project isn't fundable
How staging actually works
A few ways it gets structured.
One honest caveat Staging costs more in total than doing it all at once. Each phase means separate mobilisation, separate permits, and repeated access and patching. It's a cash-flow decision, not a saving. If you can do it in one project, that's cheaper — staging exists because sometimes you can't, and phased-but-progressing beats postponed-indefinitely.
One-time items
What can't be staged
Some elements are one-time regardless of how the branch circuits are phased.
- The panel. If it's full, obsolete, or a known-problem type, it usually needs doing first — because every new circuit has to land somewhere.
- Grounding and bonding. The grounding electrode system serves the whole property. It gets brought up to standard once, generally alongside the panel.
- Service capacity. If the incoming service is genuinely undersized for the finished plan, upgrading it partway through means paying to work around it twice.
- Anything actively unsafe. Damaged conductors, overheating connections, and circuits already failing don't wait for their phase.
The usual sequence is panel and grounding first, then branch circuits by whatever staging logic suits you.
System, not fault
Signs it's the wiring rather than a fault
A single dead outlet or one tripping breaker is usually a connection. These point at the system.
- Widespread two-prong outlets. No equipment ground on those circuits, and not solvable device by device.
- The same fault appearing in different places. When separate connections keep failing across a property, the installation method or the cable is the common factor.
- Breakers tripping on multiple circuits. The system as a whole is being asked for more than it was built for.
- Extension cords as permanent infrastructure. Too few outlets on too few circuits.
- Insulation visibly crumbling at the panel or at ceiling boxes.
- Knob and tube still in service, particularly where insulation has been added around it.
- Aluminum branch circuits with a history of loose or heating terminations.
- Insurance questions about wiring type, panel brand, or service size.
Anything hot, scorched, or smelling of burning is urgent rather than a planning matter.
Wiring types
What we replace
Knob and tube
Ungrounded, damaged easily by later work, and dependent on air space that modern insulation removes.
Cloth and rubber insulation
Embrittles and flakes off the conductor, worst at the panel and at ceiling boxes where fixture heat has accumulated for decades.
Aluminum branch circuits
Terminations loosen through expansion and contraction and heat as a result. Approved remediation is sometimes an alternative to replacement — we'll lay out both.
Ungrounded two-conductor cable
Works until there's a fault, at which point there's no safe path.
Undersized circuits
Adequate when installed, insufficient for current use.
Earlier unpermitted work
Frequently the worst thing found during a rewire.
Why Superior calls us
What you get when you call Frontier Electric
We establish what's original before quoting
The proportion already replaced drives the entire number.
We'll propose partial or staged where it fits
A contractor who only ever quotes full rewires isn't assessing the property.
The scope is written down
What's in, what's out, how many openings, what condition they're left in, and where our work ends. That last point is where these projects most often sour.
Each phase is complete
Staged work means finished, permitted, inspected phases — not a job left half open.
Licensed, insured, permitted
Documentation handed over at the end of each phase.

Scope of work
What a rewire includes
- New branch circuit wiring throughout the areas in scope
- Grounding on every circuit, and grounded receptacles
- New outlets, switches, and boxes
- Dedicated circuits for appliances and high-draw equipment
- GFCI protection in kitchens, bathrooms, laundry, garages, and exterior locations
- AFCI protection where current requirements call for it
- Additional outlets to remove reliance on extension cords
- Panel replacement or service upgrade where required
- Testing and a legible panel schedule
- Permits, inspection, and handover documentation
Living through it
The disruption, honestly
- Openings. The wiring is inside the walls. Expect access holes at plates, boxes, and direction changes — more than you're picturing, kept as small and discreet as the job allows.
- Dust. Cutting plaster and drywall makes it. We contain and protect, but it isn't a clean process.
- Power. We work in sections, so the whole property is rarely dead at once. You'll know in advance which areas are affected and when, and supply is restored at the end of each working day wherever possible.
- Timeline. Days to weeks depending on scope, size, and construction. Plaster and lath is slower than drywall; finished basements and multi-storey layouts slower than bungalows with attic access.
- Where our scope ends. Openings are patched to ready-for-paint. Final finishing, texture matching, and painting are typically separate — stated before we start, not after.
Staging reduces the impact per phase, which is one of its genuine advantages beyond cash flow. A single floor for a week is more manageable than a whole house for three.
Timing
The cheapest time to do it
Open walls remove the most expensive part of the job. Fishing cable through finished construction, cutting access, and patching afterward is a large share of a retrofit rewire's cost — and it disappears entirely when the studs are exposed.
The worst sequence is rewiring after a renovation, cutting into new drywall, tile, and paint.
If a kitchen, bathroom, basement, or addition is anywhere in your plans, say so at the assessment. Even where a full rewire isn't warranted, running circuits or conduit while things are open costs very little compared with revisiting it.
Paperwork
Permits, insurance, and resale
Rewiring is permitted, inspected work — the only independent verification you'll ever have of something now sealed inside your walls.
- Insurers ask about knob and tube, aluminum, fuse panels, and service size. Documented replacement is frequently what clears a coverage condition.
- Buyers and inspectors look for permits. Undocumented electrical work raises questions about everything else.
- For you, inspection is confirmation the work was done properly.
Keep the permit and sign-off from each phase together with the panel schedule.
Commercial
Commercial and multi-unit rewiring
We rewire offices, retail, restaurants, warehouses, and multi-unit residential buildings across Superior.
These bring three-phase supply, distribution across multiple panels, equipment-driven loads, and buildings repurposed more than once with undocumented modifications layered in. Staging is often essential rather than optional, phased around trading hours, production schedules, or tenancy turnover.
Outage windows get defined in advance so nobody discovers them on the day.
Pricing
What affects the cost
- Scope — full, partial, or staged, and how much is genuinely original.
- Property size — square footage, storeys, circuit count.
- Construction — plaster and lath, brick, and finished basements versus drywall over open framing.
- Access — attic and crawlspace availability changes everything.
- Occupied or vacant — working around a household is slower.
- Panel or service work — often required alongside.
- Added circuits — kitchens, EV charging, workshops, heating.
- Number of phases — staging adds mobilisation and permit costs per phase.
- Permits and inspection — per phase, variable by jurisdiction.
- Restoration — patching to ready-for-paint; finishing usually separate.

Questions
Frequently asked questions
Do I need to rewire the whole house?
Often not. Properties are usually a patchwork, and replacing only the original circuits is both cheaper and correct.
Can rewiring be done in stages?
Yes, in defined phases — by floor, by priority, or alongside renovations. Each phase is complete, permitted, and inspected. Note it costs more in total than a single project, so it's a cash-flow decision rather than a saving.
What has to be done first if we're staging?
Usually the panel and grounding, since every new circuit needs somewhere to land and the grounding electrode system serves the whole property. Anything actively unsafe comes first regardless.
How much does rewiring cost in Superior?
It depends overwhelmingly on scope, then size, construction, and access. The assessment establishes how much is actually original before any number is given.
How long does it take?
Days to weeks depending on scope and construction. Staged work is shorter per phase.
Do I have to move out?
Most rewires are done with the household in residence, working in sections. Staging reduces the impact further. For a large single-phase project in a small property, some people choose to be elsewhere for part of it.
How much damage will there be to walls?
Access openings are unavoidable in finished construction. They're kept small and discreet and patched to ready-for-paint. Final finishing and painting are usually separate — we'll say so up front.
Will my power be off throughout?
No. We work in sections and restore supply at the end of each day wherever possible. You'll know in advance which areas are affected.
Is knob and tube illegal?
Existing installations aren't automatically prohibited, but they can't be extended, they're incompatible with modern insulation, and many insurers won't cover properties that still have them.
Can aluminum wiring be remediated instead of replaced?
Frequently, using approved connectors at every device. Whether that suits depends on condition and sometimes your insurer. We'll give both options.
Will rewiring help with insurance?
Often. Insurers routinely ask about knob and tube, aluminum, fuse panels, and service size, and documented replacement usually resolves the condition. Keep the paperwork.
Should I rewire before or after renovating?
Before or during. Open walls remove the most expensive part. Rewiring after new finishes is the worst possible order.
I've just bought an older house. Where do I start?
An assessment. Knowing what's actually in the walls shapes every other decision about the property, and it's far cheaper than discovering it mid-renovation.
It's not always all or nothing
Partial rewires are common and often correct. Staged rewires let the work progress when a single project isn't fundable. Either beats being quoted one large number for the whole house and deciding to live with it for another decade.
Frontier Electric establishes what's original, scopes it in writing, and phases it where that's the sensible route.
