About the Service

Knob-and-Tube & Aluminum Wiring Replacement, Done Right

Knob-and-tube wiring was common in homes built before the 1950s, and it has no ground wire and can be overloaded or insulated over. Aluminum branch wiring was used in some homes in the 1960s and 1970s, and it needs special care at connections. Neither one means a home is unsafe, but both deserve a careful look.

We inspect what you have, explain the condition, and propose options that range from targeted updates to a full rewire. We plan the work to protect plaster, trim and finishes, using attics, basements and crawl spaces wherever we can.

Music City Electrical brings knob-and-tube & aluminum wiring replacement to homes and businesses in Nashville and across 22 Middle Tennessee cities.

Good to Know

Questions About Knob-and-Tube & Aluminum Wiring

Still have a question?

Call 615-357-7797

Is knob-and-tube wiring dangerous?

It can be, especially if it is overloaded, damaged or covered with insulation, because it has no ground wire. A licensed electrician can inspect it and tell you its condition and your options.

Do I have to replace aluminum wiring?

Not always. Special connectors and devices can make aluminum branch wiring safer, but a full replacement is the most thorough solution. We explain the options after inspecting your home.

Will insurance companies care about old wiring?

Some insurers ask about knob-and-tube or aluminum wiring. We provide documentation of any updates we make, which may help with your insurer.
