About Rewiring a House

According to the National Fire Protection Association, faulty electrical wiring is a leading cause of residential fires. While rewiring your house might not be the most exciting project, it could be the most important safety improvement you make.

You may need whole-house rewiring if:

  • Your outlets are all two-prong and don’t support grounded plugs.

  • Your breakers trip frequently when using appliances.

  • You feel a slight shock or tingling sensation when touching appliances.

  • You notice a persistent burning smell near appliances or in certain rooms.

If you’ve experienced any of these issues, contact Penna Electric today for a free estimate.

The Cost to Rewire a House

The cost to rewire a house in Los Angeles can vary widely depending on your home’s size, age, layout, and accessibility. Labor and materials are both major factors, and older homes often require more careful work.

Rewiring involves removing outdated wires and replacing them with modern, code-compliant wiring—usually non-metallic wires encased in plastic. Though it can be costly upfront, it’s typically a one-time upgrade that enhances safety and increases property value.

FAQ

It’s usually a good idea to let the electrician check the wiring in your home, as they have a proper and exhaustive inspection procedure. However, there are a few steps you can take to check what kind of wiring you have in your house. 

You can check if aluminum is the type of wiring in your house by looking on the outer jacket of the cables at your electrical panel for the letters AL or ALUM. 

You can check if you have knob & tube wiring by checking when your house was built and if there have been any updates in its wiring. If the house has been built in the 50s or before, then this is most likely the type you have.

There are several signs that show electricians when they need to rewire a house. Old wiring is the first one, but you also need rewiring if you hear sizzling sounds or feel burning smells, or if your breakers are tripped frequently. You can learn more about the signs here.

Older wiring types are not only out-of-date with today’s codes, they are dangerous. The outlets are ungrounded posing both shock and surges hazards.

Aluminum Wiring – For a period of about seven years, homes were built using aluminum wiring. The instability of this wiring type due to its tendency to expand and contract in heat and cold wasn’t recognized until it was too late for many homeowners. Homes with aluminum wiring are 55% more likely to experience a home fire.

Knob & Tube Wiring – A hundred years ago, most homes used knob and tube wiring throughout the house. These porcelain connectors are ungrounded and as any historic homeowner can tell you, the outlets will not support today’s electronic devices.

If you are ready to take on the task of rewiring a  house, you may want to consider advances in technology with the use of structured cabling. Structured cables are heavy-duty electrical and data cables that are combined to carry power, phone, Internet, lighting and heating throughout the rooms in your home. Structured electrical wiring has also been proven to increase the value of your home.

The cost to rewire a house varies greatly between $3,000 and $25,000 depending on the size of the house but other factors as well. You can find out more about the price and what impacts it here.

We understand that whole-house wiring for existing residences is often cost-prohibitive. Aside from the expense of rewiring your entire house, the project usually takes several days and involves repairing holes in the drywall that are required to access the existing wiring.

When this downtime and expense is not an option for you, the Penna Electric residential electricians can still help bring your home up to code and improve the overall safety. Oftentimes we are able to make suggestions that can drastically reduce the cost of your project through adding a few grounded plugs to accommodate your needs.

Not with us. We use techniques like notching that require minimal wall openings. Our team works cleanly and restores affected areas before finishing.

The time it takes depends on the size and complexity of the home, but most full rewires take between 3 to 10 days. We work efficiently and minimize disruptions to your daily routine.
