The cost of running electricity to a shed or outbuilding ranges from $10 to $25 per linear foot of ground line, depending on the type of soil and the distance from the house to the shed.
The average cost to wire a basement ranges from $2,000 to $13,500, depending on size, layout and site conditions.
Wiring an unfinished, open floor plan basement from the main electrical panel costs less than wiring a basement with a new subpanel and multiple rooms and outlets, switches, and fixtures in each room.
Electrical rough-in labor involves pulling all the wiring through wall studs and installing junction boxes for outlets, switches and fixtures. The electrician leaves the final connections unfinished until the contractors complete additional construction steps.

The average cost to replace an electrical panel is $850 to $2,500, depending on size, amperage and circuits. An upgrade from a 100-amp to a 200-amp panel costs $1,400 to $2,800. Most newer homes have 200-amp service panels.
The National Electrical Code (NEC) requires a certain number of outlets and type of switches per room when installing new electrical wiring.
The cost to rewire a home can range from $5 to $17 per square foot, depending on age, size, number of circuits and wiring accessibility.
Rewiring involves cutting into the drywall to fish new wiring circuits through the walls. Homes without a basement, attic or crawlspace may need to completely open the walls.

The average cost to replace knob and tube wiring is $12,000 to $35,000, or $8 to $17 per square foot. Knob and tube wiring was used in many homes until the 1950s but does not meet current electrical safety standards.
The cost of electrical wire ranges from $0.10 to $4.00 per linear foot for material alone, depending on the type. Non-metallic sheathed cable—also known as NM or “Romex” cable—costs $0.50 to $3.00 per linear foot and is the most common wiring used in residential construction.
Conduit prices range from $0.70 to $8.00 per linear foot. Electricians use conduit to protect electrical wiring in exposed or unfinished areas.
Commercial electrical costs range from $7 to $15 per square foot, depending on type and scale. Commercial wiring typically costs 10% to 30% more than residential electrical work due to increased electrical demands and more stringent building codes.

A typical new home takes 1 to 3+ weeks to wire the home. Wiring a larger home or one with many additional features can take several months. Most contractors plan on 1 to 2+ hours per connection. Crew and house size, specifications and inspections will affect total wiring time.
Wiring in your home can last 50 to 70+ years if properly installed under ideal conditions. The protective shield of the wires usually breaks down faster than the wire itself. Replace electrical wiring if it is ungrounded or if the protective sheathing is damaged.
Experts recommend an electrical inspection for homes 25+ years old to make sure the wiring is still safe and up to code.
We track millions of estimates that homeowners get from contractors and share those prices with you. We are committed to strict editorial integrity. The average cost to rewire a home ranges from $10,000 to $30,000 or $5 to $17 per square foot. The total cost of rewiring a home depends on location, age, size, number of rooms, wiring convenience, and wire and material costs. Rewiring an older home may require additional updates.
Commercial Electrician In Baltimore, Md
Electricians charge $50 to $130 an hour to rewire a home. Most contractors estimate at least one hour per 100 square feet for wiring installation. Rewiring usually requires at least a two-person crew when the project involves fishing wiring through closed walls.
Electrical wiring costs $0.10 to $4.00 per linear foot for materials alone, depending on the type. The total material cost depends on the size of the house and the number and type of circuits.
Conduit prices range from $0.70 to $8.00+ per linear foot including labor. Conduit is a flexible or rigid tube that protects electrical wiring in exposed or unfinished areas.
The cost of rewiring a house with plaster walls is higher than rewiring with drywall because of the high cost of plaster repair. Both jobs involve making several small holes to fish new wiring through the walls, if the home has access to a basement, attic, or crawl space.

Completely opening the walls to rewire the electrical system can add 25% to 30% to the total project cost, but this method may be the only option for older homes that lack access.
The cost to replace an electrical panel is $850 to $2,500. Many older homes have a fuse box or 60-amp circuit breaker panel, inadequate for today’s modern appliances and increased electrical demands. A 150- or 200-amp service panel is ideal for most homes.
Replacing ungrounded outlets with GFCI outlets can be a cheaper alternative to protect home occupants from electric shock without rewiring the entire house. An electrical inspection can determine the best options.
Wiring an older home is more complicated than wiring a new construction home because the wiring is hidden behind walls and ceilings.
How Much Does Electrical Wiring Cost? (2024)
New construction electrical wiring costs $4 to $9 per square foot, or $6,000 to $22,500 for a 1,500 to 2,500 square foot home. However, new construction will incur additional setup costs:
Pre-1950 homes typically have knob and tube wiring, which does not meet current safety standards. Knob and tube wiring replacement costs $12, 000 to $35, 000. The project also typically requires upgrading the electrical service panel and adding new outlets and fixtures to handle today’s high power demands.
Look for “old house electrician” when searching for a professional to rewire an old house, as the challenges of working with an old house require experienced skill.
The cost of rewiring a small house or mobile home ranges from $2,000 to $17,000. As with larger homes, the total cost of rewiring depends on the number of circuits and accessibility. Rewiring a home in a crawlspace or attic is usually less expensive because the wiring is easier to reach.

Rewiring a home adds value if the home’s wiring is outdated or malfunctioning. Even if rewiring doesn’t increase the estimate significantly, many potential buyers will lower their offer or require a discount if they find old wiring on inspection.
Rewiring a home can take 3 to 10+ days, depending on the size and age of the home, the size of the crew, and the complexity of the job. Rewiring projects that cut through walls take longer because of the added demo, repair, and clean-up.
Experts recommend rewiring a home—at least partially—every 25 to 30 years. Properly installed wiring can last 50 to 70 years under ideal conditions, but your home may need updating sooner due to technological advances, increased electrical demands, and evolving safety regulations.
Some older homes may not require complete rewiring. Hire a licensed electrical inspector to assess and determine if rewiring is necessary.
Electrical Business Proposal
You can rewire the house in stages, but most electrical contractors recommend rewiring the entire house at once when possible. Rewiring a house room by room takes longer and usually costs more overall.
Many local, state and federal assistance programs help homeowners bring their residences up to current safety standards, which may include house rewiring. Eligibility depends on age, income, location, project details and program type.
The USDA provides single-family housing repair loans & grants to low-income homeowners as part of the Section 504 Home Repair Program.
You can rewire a house without removing drywall in most cases by working from an attic or crawl space and fishing new wiring through small drywall holes. This method takes more time than rewiring with open walls, but keeps the walls mostly intact and lowers the overall project cost.

If you have experience with electrical wiring, know current building and electrical codes you can retrofit your own home, and your city allows homeowners to obtain an electrical permit.
Many states require a licensed and insured electrician for rewiring to be safe and code compliant.
Improper wiring can lead to electrical fires, injuries, electrocution and costly repairs. Check with your local building authorities for requirements before starting any DIY electrical work.
