By the end, readers will have a clear understanding of what to keep in mind when buying a house with aluminum wiring.
Understanding Aluminum Wiring: History and Risks
The Copper Shortage of the 1960s
In the late 1960s and early 1970s, a copper shortage linked to the Vietnam War led to a shift in home construction practices. Builders needed an alternative to copper wiring, and aluminum seemed like a good choice. It was readily available and cost less than copper.
Why Aluminum Wiring Was Used
Aluminum wiring became popular in North American homes during this period for electrical wiring. It was seen as a cost-effective solution to the copper shortage for a new home. At first, it seemed like a smart move. Aluminum is nearly as good a conductor as copper and much cheaper. However, electricians treated it the same way as copper wiring, which led to problems on a now older home.
Potential Hazards of Aluminum Wiring
The type of wiring used by home buyers is important for safe wire connections. Unfortunately, aluminum wiring has some serious drawbacks. It can be a safety hazard that causes electrical problems.
- Fire Risk: Homes with aluminum wiring are 55 times more likely to have fire hazard conditions.
- Softness: Aluminum is softer than copper. If pinched or damaged, it can overheat.
- Oxidation: Unlike copper, aluminum loses conductivity as it oxidizes. This creates resistance and overheating.
- Expansion and Contraction: Aluminum expands and contracts more than copper with temperature changes. This can lead to loose connections and electrical arcing.
- Creep: Older aluminum wire can permanently deform under load over time.
These issues can cause flickering lights, warm switch plates, and even electrical fires. The U.S. Consumer Product Safety Commission has received many reports of home fires linked to aluminum wiring. While aluminum wiring itself isn’t inherently unsafe, its properties make it more prone to problems than copper. This is why its use in residential construction was largely phased out by 1980.
Identifying Aluminum Wiring in a Home When Buying a House with Aluminum Wiring
Visual Inspection Tips When Buying a House with Aluminum Wiring
Homeowners can spot aluminum wiring through simple visual checks. The easiest place to start is the electrical panel. Look for wires with a silver-gray color, which are typically thicker than copper ones. Check for “AL” or “Aluminum” stamps on wiring terminals. In unfinished spaces like basements or attics, inspect exposed cables. Aluminum wiring has “AL” or “Aluminum” printed on its plastic sheath every few feet.
For a more thorough check, turn off the power and carefully remove outlet cover plates. If the conductors are nickel-colored, it’s likely aluminum. Remember, safety first – if unsure, call a pro. A good electrician can help identify your aluminum wire issue, ensure the safety of your home, and eliminate the safety risk associated with the type of wire.
Common Warning Signs When Buying a House with Aluminum Wiring
Aluminum wiring can show signs of trouble. Watch out for:
- Warm outlet or switch plates
- Flickering lights
- Burning smell near outlets or switches
- Scorched or melted outlets
- Malfunctioning switches or outlets
- Frequent circuit breaker trips
These symptoms might point to overheating aluminum connections, a serious fire risk.
Professional Inspection Importance
While DIY checks can help, a professional inspection is crucial. A team of electricians can safely and thoroughly examine the entire system. They’ll check connections, look for signs of oxidation or corrosion, and assess compatibility with modern devices. They know the best method for repair and replacement to address safety issues.
Homes built between 1965 and 1973 are more likely to have aluminum wiring. If your home falls in this period, getting a professional inspection is even more important. Experts can spot potential hazards and suggest necessary upgrades or repairs to ensure your home’s electrical safety.
Options for Dealing with Aluminum Wiring
Complete Rewiring When Buying a House with Aluminum Wiring
The most thorough solution for aluminum wiring issues is to replace it with copper wire on the entire property. This method eliminates the primary cause of potential hazards. It involves complete rewiring of your home. However, it’s often impractical and expensive. The cost can run between $200 to $500 per receptacle and switch, depending on the region. For a 2,100-square-foot home, the project could cost up to $15,000.
Pigtailing Methods
Pigtailing involves attaching a short section of copper wire to the ends of aluminum wire at connection points. This method is more cost-effective and a cheaper alternative than complete replacement rewiring. It’s done at all connections, including outlets, switches, light fixtures, and junction boxes. After pigtailing, standard copper wiring devices can be safely connected to the electrical system.
COPALUM and AlumiConn Connectors
The Consumer Product Safety Commission (CPSC) recommends two specific connectors for pigtailing:
- COPALUM Connectors: These use 10,000 lbs of cold-welding pressure to join copper and aluminum wiring. COPALUM is considered the safest solution and permanent fix, but it requires a certified technician for installation.
- AlumiConn Connectors: These are setscrew-type wire lugs. They’re more accessible and cost-effective, costing as low as $2.70 per connection. Any certified electrician can install them. AlumiConn connectors are flexible, allowing aluminum-to-copper, aluminum-to-aluminum, and copper-to-copper connections.
Both methods are approved by the CPSC and various insurance companies. They provide a secure connection and help prevent oxidation of aluminum conductors. While these repairs can be done by homeowners, it’s highly recommended to hire a qualified electrician for safety and proper installation.
Insurance and Mortgage Considerations
Challenges in Obtaining Insurance
Homes with aluminum wiring pose unique challenges for insurance. Many companies won’t insure these properties due to the increased fire risk. Homeowners might need to shop around to find coverage. Those who do offer policies often charge higher premiums. Some insurers may even cancel or deny coverage altogether.
To improve chances of getting insured, homeowners can:
- Get repairs done using approved methods
- Obtain certifications from licensed electricians
- Consider surplus lines insurers for coverage
Mortgage Lender Requirements
Mortgage lenders typically require homeowners insurance to protect their investments. This can complicate the process of buying a house with aluminum wiring. Government-backed loans, like FHA mortgages, may demand remediation before approval.
For conventional mortgages, the difficulty in obtaining insurance can be a roadblock. Buyers might need to contact multiple agencies to find suitable coverage. Higher premiums are likely, even if approved.
Negotiating with Sellers When Buying a House with Aluminum Wiring
When buying a house with aluminum wiring, buyers should consider:
- Budgeting for potential rewiring costs
- Asking sellers to cover part of the rewiring expenses
