The average rewire house cost in St. Louis is $1,160, but prices range between $526 and $1,808 or more. The city of St. Louis is centuries old, rich in history, and offers a diverse range of home styles. Those with older homes may have electrical systems that require upgrading, which often consists of rewiring the entire house. 

The price you can expect to pay out of pocket depends on several factors, including the age and size of your home. Let’s explore the main factors that affect the price and whether rewiring your St. Louis home can increase its value.

Rewiring a House Cost Factors in St. Louis

Rewiring a home is no small task, and the final price tag of the job will depend on factors such as the complexity of the installation, along with the size and age of your house. On the extreme low end, a simple rewiring task is about $135, but rewiring an entire home can cost $2,800 or more. 

Home Size 

The size of your home will significantly impact the rewiring cost. Larger houses will require more materials and labor hours. According to the Federal Reserve Bank of St. Louis, the median-sized home in this city is 1,840 square feet. 

Rewiring a house costs approximately $2 to $4 or more per square foot. Here is a breakdown of the average cost based on square footage:

House Size in Square FeetCost Range
1,000$2,000–$4,000
1,500$3,000–$6,000
2,000$4,000–$8,000
2,500$5,000–$10,000
3,000$6,000–$12,000

Age of Home

The age of your house will also determine the cost of rewiring it. St. Louis has a significant number of older homes, with some 100 years old or more. In fact, Flounder houses and Row houses are among the 19th and 20th century homes found in St. Louis. These types of homes may have outdated wiring systems, such as knob and tube wiring or aluminum wiring. 

Rewiring a house with knob and tube wiring will drastically increase the price because it is labor-intensive, and the rest of your electrical system, such as the panel, outlets, and switches, will also need upgrading. The average cost to rewire a house with knob and tube wiring is between $12,000 to $36,600 or more. However, this type of system is outdated and poses potential safety problems, which can lead to your homeowner’s insurance policy being canceled.

It’s best to have a qualified electrician upgrade your home to a modern electrical system that's safer and compliant with current codes. 

Materials and Wire Type

Like other electrical projects, the type of materials and wire used will influence the price. If electrical outlets, switches, and other components need updating, that will add to the cost. The type of wiring that the professional will use depends on location and environmental factors.

Wire TypeCost per Linear FootProsCons
NM-B Wire$0.94–$1.24Good for updating older homes and cost-effectiveSuitable for indoor use but not outdoors
UF-B Cable$1.16–$2.98Moisture and corrosion resistant and can be directly buried into the groundCan be difficult to repair
THHN/THWN Wire$0.24–$2.28High heat resistant and durableMoisture sensitivity

Complexity and Accessibility

It’s not shocking that the complexity of the job determines how much you can expect to pay to rewire a house. For instance, older-style homes in St. Louis, such as row houses, can be more difficult to rewire because they often have shared walls and complex layouts. Some homes may also have lath and plaster walls, which can make it more challenging to access wires. 

For instance, upgrading a home with knob and tube wiring would be significantly more complex than upgrading a house with a more up-to-date electrical system. 

Permits and Inspection Costs

Rewiring a house in St. Louis will require a permit from the city. An electrical permit usually ranges between $50 and $300, and the post-job inspection is usually included in the price. It's best to ask the electrician if all permit and inspection costs are included in the quote they provide. 

Add On Services and Additional Costs

There is the potential for additional costs when having a home rewired. For example, if the panel needs to be relocated or upgraded to a higher amperage, that can add to the price. Outlets, switches, and other components may also need to be upgraded to support modern appliances if the entire system is outdated. 

Here are the additional costs that you may need to incorporate into your budget:

Relocating electrical panel: $1,500–$4,000

Upgrading electrical panel: $1,200–$2,000

Install or Replace Outlet: $100–$450

Install Light Fixture: $198–$1,444

Cost to Hire an Electrician in St. Louis

Hiring an electrician in St. Louis costs around $310, but the range is between $150 and $470 or more. The average hourly rate for an electrician ranges from $50 to $130 per hour, depending on their skill set and level of experience. 

The hourly rate for a standard licensed electrician is between $60 and $90 per hour. However, a master electrician charges between $90 and $120 per hour. They typically command a higher rate because they have the highest level of expertise and can tackle complex jobs.

Does Rewiring Increase Home Value?

Rewiring your St. Louis home can potentially boost its value and make it more marketable to potential buyers, especially if it has an outdated electrical system. Although home values are increasing in St. Louis and the real estate market is competitive, outdated wiring can potentially deter buyers from bidding on your house. 

A home that has updated wiring offers increased electrical capacity, enhanced safety features, and reduces the risk of fires. There isn’t a specific dollar amount for the return on investment you will earn by having your home rewired, but even upgrading an electrical panel can yield a 53% ROI.
