We have all been there. You finally buy that charming older home with the perfect porch, or maybe you are knee-deep in a major renovation project, and then you flip a switch… and the lights flicker. Or worse, you hear a subtle buzzing sound behind the wall. Suddenly, the dream renovation hits a snag, and the big question pops into your head: “How much does it cost to wire a whole house?”
It is one of those questions that makes homeowners nervous, mostly because we fear the surprise bills that come with electrical work. But here is the good news: understanding the costs upfront can save you a massive amount of stress and money. Whether you are dealing with dangerous knob-and-tube wiring in a historic home or planning the electrical layout for a brand-new build, knowing the numbers is your best defense against overpaying.
Average Costs Overview
Let’s start with the big picture before we get into the nitty-gritty details. If you are looking for a quick answer, here is the national snapshot: wiring a whole house typically costs between $10,000 and $30,000.
That is a wide range. That is because the final price tag depends heavily on the specific “ecosystem” of your house. If you are building a new home with open-frame walls, the price is generally lower because the electricians can work more quickly. However, if you are rewiring an older home where professionals have to fish wires through closed drywall, the price jumps significantly.
On average, you can expect to pay between $5 and $17 per square foot. New construction usually sits on the lower end of that spectrum ($4–$9/sq ft), while complex rewiring jobs sit on the higher end due to the labor involved in opening and patching walls.
To give you a clearer idea of how size impacts your budget, take a look at this comparison table:
Cost Estimates by House Size
House Size (sq ft)New Wiring CostRewire Cost (Existing Home)Per Sq Ft Avg.
1,000 $4,000 – $9,000 $8,000 – $12,000 $8 – $12
1,500 $6,000 – $13,500 $12,000 – $18,000 $8 – $12
2,000 $8,000 – $18,000 $16,000 – $24,000 $8 – $12
2,500 $10,000 – $22,500 $20,000 – $30,000 $8 – $12
It is also important to remember that location plays a massive role in these figures. If you live in a dense urban area with a high cost of living, you could see prices inflate by 20% to 50% compared to rural areas. Conversely, in regions with lower labor costs (such as parts of Pakistan or rural US towns), the labor portion of the bill might be significantly lower.
Cost Breakdown by Components
When you get a quote from an electrician, it looks like one big, scary number at the bottom of the page. But to really understand where your money is going, we need to split that number apart. Generally speaking, the cost is split fairly evenly: Materials make up about 40–50%, and Labor makes up about 50–60%.
Let’s look at what you are actually buying.
Materials ($4,000 – $12,000)
This covers the physical “stuff” that goes into your walls.
- Copper Wire: The gold standard for safety. Prices fluctuate with the market, but you are typically looking at $0.80 to $1.60 per foot.
- Conduits and Breakers: These protect the wires and your appliances.
- Smart Features: If you want to future-proof your home with smart switches or whole-home automation preparation, expect to add $2,000+ to your material costs.
Labor ($6,000 – $18,000)
This is often the most expensive part of the quote, and for good reason. Expert electricians charge between $50 and $150 per hour. The complexity of the job dictates the hours. For example, if they have easy access through an attic, the cost drops. If they have to cut into plaster walls and crawl through tight crawlspaces, the hours (and the bill) go up.
Permits and Inspections ($500 – $2,000)
Never skip this step! You are paying for a professional to verify that your house won’t catch fire. This fee covers compliance checks with local city or county codes.
Important Extras
- Panel Upgrade: Often necessary for older homes, upgrading to a modern 200-amp panel costs between $1,500 and $4,000.
- EV Chargers: Preparing for an electric vehicle? That’s another $500 to $1,500.
Here is a detailed look at how the budget breaks down for a standard project:
Component Cost Range% of Total Notes
Wire & Conduit $2,000 – $6,000 20–30% Copper is standard; aluminum is cheaper for mains.
Outlets/Switches $1,000 – $3,000 10–15% A single new outlet installation runs $100–$185.
Service Panel $1,500 – $4,000 15–20% Essential if upgrading from 100 to 200 amps.
Labor $6,000 – $18,000 50–60% Often calculated at a $2–$4/sq ft base rate.
For a typical 2,000-square-foot home, you are likely looking at a total midpoint cost of around $20,000 for a comprehensive job.
Factors Affecting Wiring Costs
You might be wondering, “Why does my neighbor’s quote look so different from mine?” That is because wiring isn’t a “one size fits all” product. Several variables can swing the price by thousands of dollars.
The Age of Your Home
This is the single biggest factor. If your home was built before the 1950s, you might be dealing with knob-and-tube wiring. This outdated system is a major fire hazard and often uninsurable. Removing and replacing it is delicate work that can add $2,000 to $5,000 to your bill compared to a standard update.
Accessibility is Key
Electricians need to get the wire from Point A to Point B physically.
- Attic/Basement Access: If you have an unfinished basement or a roomy attic, electricians can run wires easily. Costs generally stay in the $10,000 – $20,000 range.
- Limited Access: If you have a slab foundation and a flat roof (no crawl spaces), or finished walls that need to be opened up, costs can easily soar to $20,000–$30,000+ due to the extra demolition and repair work required.
Size and Layout
Larger homes require more linear feet of wire. However, layout matters too. A sprawling single-story ranch is often cheaper to wire per square foot than a complex three-story Victorian home, simply because fishing wires vertically through multiple floors is difficult.
Wiring Type and Upgrades
Are you doing a simple replacement or upgrading?
- New vs. Rewire: A rewire of an old system generally costs 50% more than wiring a new build.
- Smart Upgrades: Adding smart lighting systems typically increases the budget by 20%.
- Solar Prep: Pre-wiring for future solar panels can add about 10%, but it saves huge money down the road.
Pro Tip: To get a rough estimate for your specific situation, use this formula: (Your Sq ft × $11). If you have a 1,500 sq ft home, that puts you at $16,500—a safe middle-of-the-road estimate to start your planning.
New vs. Old House Wiring
It is crucial to understand the differences between wiring a house under construction and one that is already standing. The work might result in the same thing (lights turning on), but the process is completely different.
New Construction: The “Easy” Path
In a new house, the “rough-in” happens when the house is just a skeleton. The studs are up, but there is no drywall. Electricians can walk through the walls, drill holes in seconds, and staple wires rapidly.
- Cost: $6,000 – $22,500 (for 1,500–2,500 sq ft).
- Speed: Fast. Usually takes 1–2 weeks.
Old House Rewiring: The “Surgical” Path
Rewiring an existing home is like performing surgery. You have to be careful not to damage the patient. Electricians have to cut holes in your drywall to run wires, remove old, dangerous materials (like cloth-wrapped wire), and work around insulation and pipes.
- Cost: $12,000 – $35,000.
- Speed: Slow. Expect 3–6 weeks of disruption.
- Hidden Costs: You will often find surprises, such as asbestos or outdated framing, that complicate the job.
AspectNew House WiringOld House Rewire
Cost Per Sq Ft $4 – $9 $5 – $17

Potential Issues : Rare Asbestos, Lead Paint, Old Panels
Regional Note: If you are reading this from Lahore or Karachi, labor dynamics differ. While materials (copper) are globally priced, local labor might cost Rs. 100,000–200,000 for a standard-sized home, which is significantly cheaper than Western labor rates.
Savings Tips and Strategies
Okay, now for the part you have been waiting for. How do you lower that $20,000 estimate without cutting corners on safety? Here are 10 proven strategies to help you save 20–30%.
Get Multiple Quotes (The Golden Rule)
Never settle for the first price. Get 3 to 5 quotes from reputable electricians. You will be shocked at how much they can vary. Seeing the spread gives you leverage in negotiations.
Negotiate the Season
Electricians have busy seasons (usually summer and pre-holidays). If you can schedule your work during their “off-season” (often mid-winter), you might be able to negotiate a 10–15% discount.
The “Sweat Equity” Discount
Labor is the highest cost. Ask your electrician if you can do the prep work. If you clear the furniture, remove old fixtures, or even handle the drywall demolition yourself, you could save $2,000 to $5,000 in billable hours.
Phase the Project
You don’t have to do it all at once. If $25,000 is too much right now, ask to rewire just the critical areas first—like the kitchen and bedrooms. This splits the cost over time.
Material Choices
While copper is required for standard outlets, check whether your local code allows aluminum wiring for the heavy service entrance cables (the big wires bringing power to the panel). It is significantly cheaper (up to 30% less) and safe for that specific application.
Bundle Your Projects
If you need a panel upgrade and a rewire, do both at the same time. Doing them separately means paying for two permits, two trip charges, and two setups. Bundling usually secures a “package deal.”
Look for Rebates
Check with your local utility company. Many offer rebates for upgrading to energy-efficient systems, LED preparations, or safer modern panels. You could get up to $500 back.
Optimize Outlet Placement
Do you really need 10 outlets in the guest bedroom? Stick to the code minimums in low-traffic rooms to save on materials and labor time.
Local Pros vs. Big Chains
Large national chains often have high overheads (marketing, managers, branded trucks). Local, independent electricians often provide the same quality work for a lower rate. In places like Pakistan, choosing a local skilled technician over a large firm can save Rs. 50 per sq ft.
Clear the Way
This sounds simple, but time is money. If the electrician has to spend 30 minutes moving your bookshelf to get to an outlet, you are paying for that time. Ensure every work area is completely clear before they arrive.
Case Study: A homeowner with a 1,500 sq ft home reduced their quote from $15,000 to $12,000 simply by cleaning out their attic to provide easy access and getting three competing quotes. That is $3,000 in savings just for being organized!
FAQs
Here are some of the most common questions homeowners ask when researching wiring costs.
How much does it cost to wire a whole house per square foot?
On average, you should budget between $5 and $17 per square foot—most standard projects land in the $8 to $12 range. If you are building new, it might be as low as $4, but extensive rewiring in difficult homes can push it toward $17.
Is rewiring really worth the investment?
Absolutely. Beyond the obvious safety benefits (reducing fire risk significantly), a newly wired home is a major selling point. It can boost your home’s value by 5% to 10%. Buyers are terrified of old wiring; having a certificate of new electrical work makes your home much more attractive.
How long does whole-house wiring take?
It depends on the scope. A new build can be “roughed in” in 1 week. A full rewire of an occupied home usually takes 3 to 6 weeks because the electricians have to work carefully around your life and your walls.
Is new wiring cheaper than rewiring?
Yes, significantly. Wiring a new house is usually 30% to 50% cheaper than rewiring an old one. The absence of drywall makes the electrician’s job much faster and easier.
