Do Insurance Companies Insure Homes with Aluminum Wiring?
Some will, often after an electrician inspects the wiring or it's updated with copper connectors, since aluminum wiring raises fire risk.

Why the aluminum wiring is the sticking point
Aluminum wiring was common in homes built in the 1960s and 1970s, and insurers treat it as a fire risk because the connections loosen over time and overheat. When one declines or non-renews for this reason, the letter usually says so directly, or a prior inspection or claim flagged it. Getting new coverage typically means having a licensed electrician inspect the wiring and either replace it with copper or pigtail the connections with approved copper connectors, a repair far cheaper than rewiring the whole house. Some insurers will cover aluminum wiring as is, sometimes with a higher premium, so it helps to get the inspection report in hand before applying again. Your declarations page or the non-renewal letter should say which reason applied to your house, since the fix depends on that.
Not every insurer treats aluminum wiring the same way
Some decline it outright, some charge more for it, and some accept it once pigtailing or an inspection report is in hand. Comparing quotes shows which insurers still fit your house.
What an electrician's inspection actually involves
An inspection for aluminum wiring isn't the same as a general home inspection. Look for an electrician who specifically mentions aluminum wiring or copper pigtailing on their license or website, since not every electrician does this work often. They'll check the connections at outlets, switches, and the breaker panel, which is where most of the overheating risk shows up. A full rewire isn't usually needed. Pigtailing, where a short piece of copper wire is connected to the aluminum wire with an approved connector, then wired to the outlet or switch, fixes the problem at each connection point without tearing into walls.
Ask the electrician for a written report when the work is done, not just a verbal confirmation. The report should state what was inspected, what was found, and what was repaired or connectors used. Insurers that accept aluminum wiring after pigtailing will usually want to see this document, and having it ready before applying saves a round of back and forth. Some electricians use the term AlumiConn or COPALUM for the connectors they install, and naming the brand on the report can help since some insurers ask for that detail specifically.
How much this costs depends on the size of the house and the number of connection points, but pigtailing the whole house typically runs far less than rewiring it, since no new wire is being run through the walls. A full rewire is sometimes recommended anyway if the wiring is old enough that other problems are showing up, like worn insulation or outdated panel capacity, but that's a separate decision from what's needed to satisfy an insurer.
If the inspection finds the wiring was already pigtailed by a previous owner, ask for documentation of that work too. Insurers want to see who did it and when, not just that it looks fine. A house with no paperwork on prior electrical work often gets treated the same as one with no work done at all, even if the repairs are sound.
What happens if the inspection finds other problems
Sometimes the electrician comes back with more than an aluminum wiring issue. Double-tapped breakers, missing grounds, an overloaded panel. These turn up often enough in houses old enough to have aluminum wiring in the first place, since the two tend to come from the same era of electrical work. None of this means the aluminum wiring findings are wrong, but it does mean the report may list more than one thing that needs fixing before an insurer signs off.
Ask the electrician to separate what's required from what's recommended. A loose ground wire at the panel is a safety issue most insurers will want addressed. A panel that's merely older but still functioning might just be noted, not flagged as a condition of coverage. Mixing the two together in one estimate makes it harder to know what's actually standing between you and a policy versus what's a good idea to fix eventually.
If the list is long, get the quote for just the aluminum wiring fix priced separately from anything else. Some homeowners end up doing the pigtailing now and holding off on a panel upgrade for later, since insurers are usually reacting to the fire risk from the aluminum connections specifically, not the overall age of the electrical system. Check with whichever insurer you're applying to about which items they actually require before paying for everything on the list.
Keep every receipt and report from this point forward, even for work that seems unrelated to the wiring. A house with a paper trail showing ongoing electrical maintenance reads differently to an underwriter than one with a single inspection report and no other history. If you end up switching insurers again down the road, the same documents save time a second time.
Before you apply again
Check your non-renewal letter for the exact reason given, then get the electrician's written report, naming the connectors used, ready to send with your application. Compare quotes once you have it.
