Will Homeowners Insurance Cover Aluminum Wiring?
Damage itself is usually covered, but insurers often require an inspection or rewiring before issuing or renewing a policy with aluminum wiring.

Why aluminum wiring triggered the letter
If your policy was canceled or not renewed over aluminum wiring, it's not because of a fire you had. It's because insurers treat aluminum wiring as a higher fire risk than copper, especially in homes wired before the mid-1970s, and some won't renew a policy once they find out it's there. An inspection usually decides what happens next. If a licensed electrician finds the wiring was pigtailed with copper connectors or otherwise updated to current standards, some insurers will write the policy. If it's untouched, you'll likely be asked to have it corrected before coverage starts. Check your old policy's declarations page or any inspection notes for mentions of wiring type. When you apply again, expect the new insurer to ask directly, and answering accurately avoids another non-renewal down the road.
Insurers that treat aluminum wiring as a dealbreaker aren't all alike. Some won't write the policy at all. Others will, once a licensed electrician confirms the connections were pigtailed with copper. That difference decides whether you're covered next week or still searching after the deadline passes. Comparing quotes now shows which insurers accept your house as it is and which ones expect repairs first.
What fixing the wiring actually involves
Pigtailing is the repair insurers usually mean when they ask for aluminum wiring to be corrected. An electrician attaches a short length of copper wire to each aluminum conductor using a connector rated for both metals. The copper then runs to the outlet, switch or fixture, while the aluminum wiring stays in the walls. Only the connections change. It runs a few hundred dollars per connection point in most houses, not a rewire of the whole structure, though a house with many outlets and switches adds up.
Full rewiring is the other option, and it's a different scale of project. New copper wiring gets pulled through the house and the aluminum is retired entirely. It costs far more than pigtailing and usually means opening walls. Most homeowners only go this route if the wiring has other problems beyond the aluminum itself, or if an electrician finds damage that pigtailing wouldn't fix.
Either way, get the work documented. A licensed electrician should provide a written statement describing what was done, which connectors were used, and that the work meets current code. Some insurers want a permit and inspection from the local building department too, not just the electrician's word. Keep a copy for yourself in addition to whatever you send the insurer. You'll likely need to show it again at the next renewal or if you switch companies later.
Not every insurer requires pigtailing before they'll write a policy. Some will insure the house as is and charge more or exclude certain claims tied to the wiring, which your declarations page or policy exclusions would spell out. Others require proof of the repair up front. A few ask for a full electrical inspection regardless of what's been done, just to see the panel and connections for themselves. Knowing which kind of insurer you're dealing with before you apply saves a round of back and forth, especially with a deadline from a cancellation letter already running.
How to tell if your wiring is actually aluminum
Before any of this matters, it helps to know for certain what's in the walls. Aluminum wiring shows up almost entirely in houses built or added onto between 1965 and 1973, when copper prices pushed builders toward it. If your house was built outside that window, aluminum branch wiring is unlikely, though it's not impossible if a room was added or rewired during those years.
The marking is usually right on the wire itself. At the breaker panel, or at any outlet or switch with the cover plate off, look at the sheathing for the word "aluminum" or the abbreviation "AL". Copper wire is unmarked or says "CU". If you can see bare wire at a connection, aluminum has a dull, silvery color, while copper is reddish-brown. A flashlight and a willingness to pull a cover plate off one outlet usually settles it without hiring anyone.
If you'd rather not open anything up yourself, a licensed electrician can confirm it in the time it takes to do a basic panel inspection, and that inspection is the same one most insurers will eventually ask for anyway. Some home inspection reports from when you bought the house already note the wiring type, so check that paperwork before paying for a new visit. A previous insurer's underwriting file or inspection notes, if you can get a copy, sometimes mentions it too.
Knowing the answer before you apply for a new policy changes how the conversation goes. An insurer that asks and gets a clear, documented answer, aluminum present, pigtailed in this year, by this electrician, moves faster than one left to guess or wait on your own inspection. Given a deadline from a cancellation or non-renewal letter, that head start is worth having.
Before you apply again
Pull your cover plates or check the breaker panel for the word aluminum or AL on the wiring. Knowing the answer, and having any pigtailing documented, changes how fast a new insurer can quote you.
