Tucson grew fast in the 1950s, 60s and 70s, and a lot of those houses still have the wiring they were built with: aluminum branch circuits, ungrounded two-wire circuits, cloth-insulated cable. Some of it is a real hazard and some of it is fine. Arizona Electrical Solutions is a licensed electrical contractor (ROC CR-11) that does permitted, inspected rewiring — and that will tell you when the cheaper fix is the right one.

What It Involves
“Rewire” covers very different jobs. Aluminum branch-circuit wiring, installed in many Tucson homes built roughly 1965 to 1973, has a documented history of overheating at connections; the fix can be a listed connector at every termination or a full copper replacement. Ungrounded two-wire circuits in pre-1960s homes are not a fire hazard in themselves, but they leave three-prong receptacles with no ground and no place for a surge protector to dump. Cloth-insulated cable from the same era becomes brittle and is the most common reason a full rewire is genuinely needed.
A full rewire on a slab-on-grade Tucson home is invasive work — attic runs, wall openings, patching. We do it, and we do it under a permit with rough-in and final inspections. But we would rather scope the problem accurately first, because a house that needs aluminum remediation does not need every wall opened.
Remediation with listed aluminum-to-copper connectors at every device, switch and fixture, or replacement with copper. Which one is right depends on the condition and the budget; both are permitted work.
Same era, same concern: FPE panels →New grounded circuits where you need them, or GFCI protection as the code-allowed alternative for existing two-wire receptacles. Not every ungrounded circuit needs to be replaced.
Often done with a panel change →Complete replacement of the branch circuits, new devices, AFCI and GFCI protection to current code, and usually a new panel — because the old one was not built for the circuit count a modern home has.

A full rewire is the most disruptive residential electrical job there is. These are the situations that justify it, and the ones that usually do not.
A four-point inspection or an insurer’s letter often names aluminum wiring or an FPE panel. Those are specific, fixable problems. Ask for the report; the fix is usually narrower than “rewire the house”.
In an aluminum-wired home these are the classic signs of a failing connection and they are urgent. Remediation at every termination is the answer; it is a day or two of work, not a gutted house.
When cloth-insulated cable crumbles at every box, the circuits are past their life and a full rewire is the honest recommendation. We will show you what we found, not just tell you.
You may not need a rewire. GFCI protection on an ungrounded circuit is a code-recognised fix, properly labelled. A rewire for grounded outlets alone is usually money that could go into the panel instead.
How We Work
We start by opening a sample of boxes and looking at the panel — the conductors, the terminations, the breaker type — and we write down what we found. That becomes the scope: aluminum remediation, targeted circuit replacement, or a whole-house rewire with a new panel. You get a description of the problem that another electrician could read and check.
The work is permitted and inspected at rough-in and at final. On a slab-on-grade house that means attic runs and controlled wall openings, patched and ready for paint. A rewire is also the natural time for a panel or service upgrade, since every circuit is being landed anyway.
Tucson Specifics
The build year narrows it fast. Tucson homes from the mid-1960s to early 1970s are the aluminum-wiring years, and the same era carries the Federal Pacific and Zinsco panels insurers ask about. Pre-1960 homes in the central neighbourhoods are where two-wire ungrounded circuits and cloth cable turn up. Block homes on a slab, with no crawlspace, are the ones where the routing takes planning.
Our free property lookup reads the county record for your address — build year, jurisdiction, and what has already been permitted — and it is the first thing we check.
FAQ
Usually not. Aluminum branch-circuit wiring fails at the connections, not along the cable, and the accepted fix is a listed aluminum-to-copper connector at every termination — each receptacle, switch, fixture and splice — done under a permit. A full copper rewire is the more expensive, more permanent option. We explain both and let you choose.
A whole-house rewire is priced from the house: the number of circuits, the construction (attic access, slab, block walls), and whether the panel changes with it. We quote it from a site visit with written findings. The panel and service side can be priced now with the cost calculator.
Yes. Rewiring is permitted, inspected work in every Tucson-area jurisdiction, with a rough-in inspection before the walls are closed and a final. Unpermitted rewiring is one of the things a buyer’s inspector looks for, and it is far harder to fix after the drywall is back up.
Sometimes without rewiring. The code allows a GFCI-protected receptacle on an ungrounded circuit, labelled “No Equipment Ground”, and for many rooms that is the practical answer. Where you genuinely need a ground — a surge protector, certain appliances — a new grounded circuit is run for that location.
On a slab-on-grade Tucson house most circuits route through the attic and down the walls, so openings are at device locations and where a run has to turn. We plan the routing to minimise them and patch what we open. It is disruptive; it is not a gut.
Almost always, if it is original. A rewire lands every circuit in the panel anyway, and a 1960s or 70s panel — especially a Federal Pacific or Zinsco — was not built for the circuit count or the AFCI breakers a rewired house has. See our residential panel upgrade page.
