Can You Get House Insurance with Aluminum Wiring?
Yes, though insurers often require an inspection or proof the wiring was updated or pigtailed with copper connectors first.

Why aluminum wiring triggered your letter
Aluminum wiring was common in homes built roughly between 1965 and 1975, and insurers treat it as a fire risk because the connections can loosen and overheat over time. If that's why you got dropped, the insurer isn't saying the house is uninsurable, just that they won't take the risk as it stands. An electrician can inspect the wiring and either replace it with copper or pigtail each connection with copper connectors rated for aluminum, which satisfies most insurers without a full rewire. Get a written report after the work, since underwriters will ask for proof, not just your word. Check your cancellation letter for the exact reason given. If it names the wiring specifically, that inspection report is what gets you back to normal coverage.
Insurers differ a lot on aluminum wiring. Some decline it outright, some accept it with an inspection report, some only want proof of pigtailing on the circuits that matter. One company's non-renewal doesn't mean the next one sees it the same way, and the price for comparable coverage can vary more than the wiring itself justifies. Worth checking before the deadline in your letter arrives.
What an electrician actually checks before signing off
An inspection for aluminum wiring isn't a quick glance at the breaker panel. The electrician traces circuits to find where aluminum wire connects to switches, outlets, and light fixtures, since those are the spots most likely to loosen and heat up. Breaker panels and major appliance circuits sometimes get more scrutiny because they carry more load. If the house has already had some rooms rewired or pigtailed by a previous owner, the electrician notes which circuits are done and which aren't, since a partial fix won't satisfy most insurers.
The report you get afterward matters as much as the work itself. It should state which connectors were used, since not all pigtail connectors are rated for aluminum to copper connections, and the wrong type creates the same overheating risk the insurer is worried about. Look for the connector brand or type listed, usually a twist-on connector approved for aluminum repairs, along with which circuits were addressed. A report that just says 'wiring inspected, no issues found' without specifics is less useful to an underwriter than one that documents the actual repair.
Cost and scope vary by house. A smaller home with aluminum wiring on a handful of circuits might only need pigtailing at each outlet and switch, which an electrician can often complete in a day or two. A larger or older home, or one where the aluminum wiring feeds the whole panel, may call for a more complete rewire, which takes longer and costs more. Either way, ask the electrician for an itemized invoice alongside the inspection report, since underwriters sometimes want both the proof of repair and the proof it was done by a licensed professional.
If your non-renewal letter gave a deadline, get the inspection scheduled well before it rather than waiting to see if the current insurer reverses course. Some insurers will reconsider a non-renewal once they receive the report, but most treat it as a new application instead, which means starting the comparison process regardless. Having the report in hand before you request quotes also means any insurer you ask can give you a real answer right away instead of a conditional one.
Does the whole house need rewiring, or just some outlets?
Most houses with aluminum wiring don't need a full rewire to satisfy an insurer. The usual fix is pigtailing, where an electrician attaches a short length of copper wire to each aluminum connection using a connector rated for that pairing, then wires the switch or outlet to the copper pigtail instead of the aluminum directly. This stops the aluminum-to-device connection from loosening, which is the actual failure point insurers are worried about. A full rewire replaces the aluminum wiring itself, which costs more and takes longer, and is usually only necessary if the wiring is damaged, undersized for the home's current electrical load, or if local code requires it for other reasons.
Whether pigtailing is enough depends on what an insurer wants to see, and that varies. Some accept pigtailing on every outlet, switch, and light fixture the aluminum wire touches. Others want pigtailing plus a look at the breaker panel, since older panels weren't always designed for aluminum and can have the same loose-connection problem at the breakers themselves. A few insurers, especially after a prior claim or if the house has other red flags, may ask for a full rewire regardless of whether pigtailing was done. The non-renewal letter or a call to the prior insurer sometimes clarifies which one applies to your case, but an electrician familiar with insurance requirements can usually tell you which standard is typical for the area.
Partial work from a previous owner complicates things. If some rooms were pigtailed years ago and others weren't, the whole house isn't covered by that old work, and an insurer will likely still flag the untouched circuits. The inspection report should say explicitly which circuits have copper pigtails and which still have aluminum connected directly to devices, so there's no ambiguity about what's left to do. Walking into a quote request with that kind of clarity, rather than a vague sense that 'some of it was fixed,' makes the underwriting answer faster and more reliable.
Cost is the other factor pushing people toward pigtailing over a rewire. Pigtailing a typical home runs a fraction of what a full rewire costs, since it doesn't involve opening walls or replacing the wire itself. That's part of why insurers who understand aluminum wiring often accept it as sufficient. A full rewire makes sense when the wiring is old enough or damaged enough that fixing individual connections won't address the underlying problem, but for most houses where the wiring is just original aluminum from the era it was common, pigtailing with a documented inspection report is what gets coverage back in place.
Before you request quotes
Pull your cancellation letter and check whether it names the wiring specifically. If it does, get the inspection and pigtailing report in hand first. Insurers can give a real answer instead of a conditional one.
