How Much Does it Cost to Rewire a House?

What You Need to Know About Home Rewiring Costs

As a homeowner, you must understand that your house’s electrical system is one of the vital aspects of your property. An outdated or faulty electrical system can lead to potential risks such as high energy bills, fire hazards, or even electrocution. That’s why it’s essential to consider rewiring your home for safety reasons. But how much does it cost to rewire a house? This may be a question lingering in your mind, and we are here to shed some light on this topic.

Several factors determine how much it costs to rewire a house, including the size and age of the house, the design of the electrical system, and your location. Let’s break down each factor to give you a better idea of what you may expect.

Size & Age

The larger the home, the higher the overall rewiring costs. A bigger house will require more materials and labor hours to ensure that all the electrical components are correctly installed. The age of the house is also a determiner. Older homes may require more rewiring and electrical upgrades to be brought up to code. Generally, rewiring an older home costs more than rewiring a newer home.

Design of the Electrical System

The electrical system’s design and complexity can also affect rewiring costs. Homes designed to accommodate 100 amps may require more electrical work to upgrade to 200 amps. Also, rewiring a house with many rooms and various appliances will require more wiring complexity than a smaller home design.

Housing Type

The cost of rewiring a home in Philadelphia can vary depending on several factors. These include the type of housing (like row homes or detached houses) and the number of stories (such as 2 or 3). It’s also important to consider the construction materials used, like plaster and lath or drywall. Taking these factors into account will help estimate the cost of rewiring your home.

Contingent Costs

There are also factors that come into play during the rewiring process itself. For example, if there are unexpected electrical defects that need fixing, it can increase the overall expenses beyond the initial quote. Additionally, houses with obstacles such as pipes and ductwork can make it more difficult for electricians to rewire efficiently, resulting in extra costs.

The wires running under the joist would not pass an electrical inspection. The correct way would be to drill a hole in the beam to run the wire. Opting for the cheaper bid may end up being more costly in the long term.
