How Much Does Rewiring a House Cost in Houston? [2025 Data]

Rewiring is a major home electrical project that replaces outdated wiring, fixes fire hazards and meets the latest electrical codes. A rewiring project for your Houston home costs on average $1,375 but most homeowners spend $576 to $2,300. This type of electrical work requires hiring a certified electrician who can provide more details about your estimate, based on cost factors in your Houston home.

Rewiring a Home Cost Factors in Houston

While minor rewiring projects start at $140, whole-home rewiring of a large house can cost up to $4,620. Here are the most important factors affecting your final estimate. 

Home Size

The size of your home is the single biggest factor in overall rewiring costs. You can expect to pay $2 to $4 per square foot for a home rewiring project. 

Materials

Home wiring has a number of accepted standards, and some wiring is more expensive than others. Wiring that needs additional fire protection or runs underground is usually more expensive because of its extra features. Low-voltage wiring is usually the most budget-friendly option.

Home Age

Modern homes have updated wiring designs that won’t require as much work as rewiring as old houses. Homes with wiring that’s decades old, especially with aluminum or knob-and-tube, require extensive replacements, which usually include upgrades to the entire electrical system, including an electrical panel. For example, it costs between $12,000 and $36,000 to replace knob-and-tube wiring. 

Accessibility

Electricians have the proper tools to access wiring in walls, and they can cut out pieces of drywall if necessary to reach wiring. However, difficult-to-access areas, like a cramped crawlspace or buried lines, will require additional labor time, increasing your service cost. The more electricians have to work to get to the wiring, the longer it will take and the more labor costs will increase. 

Repairs and Clean Up

Most electricians will add an item to their estimate for clean-up and repairs, such as patching drywall. If you feel confident in handling repairs and cleanup as a DIY project, you can ask about handling clean-up to cut down on costs. Otherwise, you can expect to pay up to $500 for clean-up costs.

Add-On Services

If wiring in a house needs to be replaced because it’s outdated or showing signs of damage, that’s a sign that other electrical components should be replaced, too. Save on labor costs by bundling multiple electrical services together.

Here are some of the additional costs that you may need to budget for:

• Upgrade electrical panel: $1,200–$2,000

• Drywall repair: $270–$750

• Replace or install outlet: $100–$450

• Replace or install light switch: $60–$300

Electrician Pro Costs in Houston

Rewiring is a large-scale project that requires experience, knowledge of Houston electrical codes, and preventative safety measures. In other words, you’ll need to hire a certified electrician. Here’s what you can expect when it comes to the costs of hiring a pro electrician. 

Licensing and Insurance

The electrician you choose must be licensed and insured in the state of Texas. Electricians have to pass exams and work for a certain number of hours to attain different levels—7,000 apprentice hours to reach Journeyman status, for example. The higher the level of electrician, the more they can charge, with master electricians being the most expensive. 

Hourly Rates and Taxes

Standard electrician rates in Texas are around $30 to $50 per hour for journeyman-level work. However, a project like rewiring may call for work from a master electrician as well, and they can have hourly rates up to $100 per hour. Electricians structure labor costs so they can bundle their labor into one overall price when creating the estimate. 

Tipping

If your electricians did a particularly good job or added extra services, a 10% to 15% tip can be an appreciated way to thank them for their work.

Permits

An electrical permit will be required to rewire your house in Houston, which will cost around $100 to $200, depending on the type of upgrades. After the work is finished, an electrical inspection is usually required, which has around a $100 fee. Electricians will handle pulling the permits, but they’ll pass the costs along to you. 

Does a New Wiring Increase Home Value?

Rewiring a home is a very important upgrade to ensure your home meets state and local electrical standards. Replacing an electrical panel can yield a 53% return on investment. Updating old wiring systems, such as knob and tube wiring or aluminum wiring, will help boost its value and make it more appealing to potential buyers. Buyers are more likely to purchase a house if they know the wiring is recent and they won’t have to arrange any upgrades to meet local electrical codes.
