State Farm will insure a house with aluminum wiring, but approval is rarely automatic. While the company does not issue an absolute nationwide ban on aluminum branch wiring, local underwriting guidelines frequently require a professional electrical inspection or documented remediation before binding a policy.
Depending on the age of the home, state regulations, and the overall condition of the electrical system, State Farm may accept the home as-is, require specific safety modifications, or charge higher premiums to offset the risk. What matters most to underwriters is whether the property features single-strand branch wiring and whether approved safety measures have been implemented by a licensed electrician.
Why Insurance Companies Flag Aluminum Wiring
Between 1965 and 1973, residential homebuilders frequently installed single-strand aluminum branch wiring due to a sharp rise in copper prices. However, single-strand aluminum behaves differently than copper inside a home’s electrical walls.
Aluminum expands and contracts significantly more than copper when electrical currents heat up the wire. Over time, this thermal movement causes wire connections at outlets, light switches, and circuit breakers to loosen. Loose connections create electrical arcing, micro-gaps, and severe heat buildup. Additionally, exposed aluminum oxidizes easily, forming a high-resistance barrier that further elevates heat levels. According to research from the U.S. Consumer Product Safety Commission (CPSC), homes wired with single-strand aluminum branch circuits are substantially more prone to fire hazard conditions at connection points than homes wired with copper.
It is important to note that multi-strand aluminum wiring—commonly used for heavy-duty service entrance cables and major appliance circuits—remains standard and safe under modern building codes. Underwriters specifically target single-strand aluminum branch circuits feeding standard 120-volt outlets and switches.
State Farm’s Underwriting Policy on Aluminum Wiring
State Farm evaluates homes on a case-by-case basis through its local agency network and regional underwriting offices. Rather than enforcing a single rigid restriction, State Farm generally categorizes aluminum-wired properties into three underwriting tiers:
- Acceptance with Proof of Remediation: State Farm typically issues standard coverage if a licensed electrical contractor has corrected the connection points using an underwriter-approved method.
- Conditional Acceptance Pending Inspection: In some regions, State Farm may bind coverage temporarily or offer a policy subject to a satisfactory 4-point inspection or electrician’s certification within 30 days.
- Surcharged Rates or Sump Restrictions: If the home has unmitigated aluminum wiring that passes a basic inspection, State Farm may still approve the policy but apply a risk surcharge to the annual premium.
If an inspection reveals active oxidation, scorched switch plates, or improper DIY connections, State Farm will decline coverage until the system is professionally repaired.
Approved Remediation Methods Accepted by Insurers
If State Farm requires you to repair or mitigate single-strand aluminum branch circuits before issuing a policy, you do not necessarily have to re-wire the entire house with copper. Complete rewiring is the safest long-term solution, but it is also the most expensive option, often costing between $8,000 and $15,000 or more.
Insurers, including State Farm, generally accept two permanent pigtailing methods that connect short pieces of copper wire to the existing aluminum ends at every fixture, outlet, and switch:
- AlumiConn Connectors: These are mechanical lug connectors where each aluminum and copper wire is secured into separate ports with set screws coated in an anti-oxidant compound. AlumiConn is widely available, cost-effective, and accepted by almost all insurance underwriters when installed to proper torque specifications.
- COPALUM Crimps: This method uses a specialized high-pressure crimping tool and metallic sleeves to create a cold-weld bond between copper and aluminum wires. While recognized by the CPSC as a top permanent fix, COPALUM requires certified technicians and proprietary equipment, making it harder to source in many regions.
Simple twist-on wire nuts—even those marketed with anti-oxidant paste—are strictly rejected by insurance underwriters and home inspectors as a permanent fix.
How to Get Approved Coverage With State Farm
Securing homeowners insurance for an aluminum-wired house requires proactive documentation. Following a clear sequence prevents unexpected policy cancellations or closing delays during a real estate transaction.
- Conduct a Thorough Inspection: Have a certified home inspector or licensed electrician check the main breaker panel and open representative junction boxes to verify the wiring material.
- Hire a Licensed Electrician: If unmitigated aluminum branch wiring is present, retain an electrician to perform AlumiConn or COPALUM remediation across all outlets, switches, and connections.
- Obtain Official Documentation: Gather the electrician’s itemized invoice, a written letter of completion detailing the exact repair method used, and any required local municipality building permits.
- Submit Documentation to State Farm: Provide the inspection report and electrician certification directly to your local State Farm agent prior to your policy effective date.
Does Homeowners Insurance Cover the Cost of Rewiring?
Homeowners insurance policies do not pay to upgrade or remediate existing aluminum wiring simply to satisfy an underwriting requirement. Standard property policies cover direct physical damage caused by sudden and accidental perils, such as a fire. Preventative electrical upgrades are classified as routine home maintenance and are the financial responsibility of the property owner.
However, if an electrical fire or another covered peril causes physical damage to your home, State Farm will pay to repair the resulting property damage according to your policy limits. If your policy includes Building Ordinance or Law coverage, it may also help absorb the extra cost of bringing surrounding damaged wiring up to current electrical codes during the repair process.
What to Do If State Farm Denies Coverage
If State Farm declines your application or conditions your policy on a full system upgrade that falls outside your current budget, you still have functional alternatives:
- Shop Independent Insurance Brokers: Independent agents represent multiple regional carriers. Some specialized surplus line insurers routinely write policies for older homes with unmitigated wiring, giving you time to complete repairs later.
- Negotiate Seller Credits: If you are buying a home, request that the seller complete approved AlumiConn pigtailing prior to closing, or ask for a price concession at settlement to cover post-closing electrical work.
- Request a Temporary Extension: If you are an existing State Farm policyholder facing non-renewal, submit a signed electrician proposal and permit application to your agent to ask for a deadline extension while repairs are scheduled.
State Farm remains a viable option for homes built during the aluminum wiring era, provided you verify the electrical system’s condition and supply clear proof of proper safety mitigation.
