Aluminum Wiring Repair in Broken Arrow and Tulsa

Aluminum wiring repair for Broken Arrow and Tulsa homes

Many homes built in the mid-1960s through the mid-1970s were wired with aluminum branch circuits instead of copper. Aluminum wiring is not automatically dangerous, but it behaves differently from copper. It expands and contracts more with heat, it oxidizes, and it does not hold tight under screws and devices that were made for copper. Over years, those connections loosen and run hot. Aluminum wiring repair makes every connection safe, and Hot Shot Electric Service Co. has done it in Broken Arrow, Tulsa, Coweta and the surrounding towns for decades.

How to tell if you have aluminum wiring

• Your home was built roughly between 1965 and 1975
• Wire visible in the attic, basement or panel is dull silver rather than copper colored
• The cable jacket is stamped AL or ALUMINUM
• A home inspection report mentions single-strand aluminum branch wiring

Please do not open outlets or the panel to look. If you are not sure, a journeyman can tell you in a few minutes during any visit.

Warning signs at outlets and switches

• Cover plates that feel warm
• Outlets or switches that flicker, buzz or work only sometimes
• A faint burning plastic smell near a device
• Discoloration around an outlet or switch
• Lights that dim when something else on the circuit turns on

Our repair method: copper pigtails with AlumiConn connectors

The most widely recognized repair for aluminum branch wiring is to attach a short copper wire, called a pigtail, to the aluminum at every connection point, using a connector specifically listed for joining aluminum to copper. We use AlumiConn connectors for this. The outlet, switch or fixture then connects to copper, the way it was designed to. The aluminum stays in the walls, but every place it connects to anything is made safe.

1. We confirm which circuits are aluminum and check the panel connections first.
2. At every outlet, switch, fixture and junction box on those circuits, the aluminum conductor is cleaned and pigtailed to copper with a listed connector.
3. Devices are replaced as needed so nothing relies on an old aluminum-rated screw terminal.
4. Each circuit is tested, and you get a list of what was done.

One customer had a whole house handled in one project: a new breaker box along with every outlet and switch in the house, including new aluminum-to-copper connectors.

When rewiring makes more sense

Pigtailing is the right answer for most homes. Rewiring with copper is the complete answer, and it makes sense when walls are already open for a remodel, when the wiring is damaged, or when you are adding many new circuits anyway. We will price both so you can choose. See electrical wiring and rewiring.

Aluminum wiring and your panel

Older homes with aluminum branch wiring often have older panels as well. We check the panel connections and the breakers on every aluminum circuit, because a loose lug in the panel is as much a risk as a loose outlet. If the panel itself is due, an electrical panel upgrade can be done at the same time, so the house goes from service to outlet in one project.

Insurance, home sales and inspections

Buyers, home inspectors and insurers often ask about aluminum wiring. A documented repair, done by a licensed electrical contractor with listed connectors, gives you a clear answer. If you are buying or selling, an electrical safety inspection tells you what you have before you negotiate.

Why aluminum connections loosen

Aluminum expands and contracts more than copper every time current flows and the wire warms up. Over thousands of cycles, that movement works screw terminals loose. Aluminum also forms an oxide layer that does not conduct well, so a loosening connection gets more resistant, which makes it hotter, which loosens it further. That is why the trouble shows up at outlets, switches and splices, not along the middle of the wire.

What a finished repair looks like

When the job is done, every outlet, switch, light fixture and junction box on the aluminum circuits has short copper leads connected to the aluminum with listed connectors, the devices are fastened to copper, and each circuit has been tested under load. You get a record of what was done, which is what an insurer or buyer will want to see. The aluminum stays in the walls, but it no longer connects directly to anything that was made for copper.

Not every home built in that era has aluminum. Some have it on a few circuits only, often added in a later remodel. Part of the job is confirming exactly which circuits need the work so you are not paying for rooms that are already copper.

Can I just replace the outlets?

Outlets and switches labeled CO/ALR are rated for aluminum, and they are better than standard devices on an aluminum circuit. But they only treat the device. Splices in junction boxes, connections at light fixtures and the panel connections are still aluminum to whatever they were joined to. A complete repair treats every connection point on the circuit, which is why we count them all before quoting and work through the house systematically.

Cost and scheduling

Aluminum wiring repair is priced by the number of connection points, which depends on the size of the house and how many circuits are aluminum. We count them and quote the job in writing, and estimates for planned work are free. Most homes are done in one to a few days, room by room, so you keep power in most of the house while we work.
