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

If your home needs new wiring to replace outdated materials or upgrade its electrical capabilities, you need to start by learning the rewiring costs in Seattle. Rewiring a home in Seattle costs $1,957 on average, with most homeowners spending between $836 and $3,090.  

This major electrical project must be handled by a qualified local electrician. Costs depend on the size of your home, among several other important factors. Let’s review how to budget for a Seattle home rewiring project.

Rewiring a House Cost Factors in Seattle

The best way to get an estimate for your rewiring job is to consult an electrician. These are the most important factors to consider when budgeting.

Home Size

Rewiring a house in Seattle costs between $2 and $4 per square foot, making it easy to calculate the estimated cost of this service. The size of the home is easily the most important factor in your overall rewiring costs.

Materials

Certain types of home wiring cost more than others. For example, wiring for underground use and wiring with extra fire protection tend to cost more. Large appliance wiring is usually more expensive, while low-voltage wiring for small devices is the least expensive. That’s why it’s important to consult an electrician about the best type of wiring for your home.

Preparation and Cleanup

Electricians usually bundle extra cleaning and repair costs into their overall estimate, especially if they plan to cut into drywall to reach hidden wiring systems. You can expect cleanup services after rewiring to add up to $500 to your total bill. Homeowners may be able to reduce costs if they’re willing to handle all the cleanup and repair work themselves. 

Accessibility

Electricians have a number of tricks to access wiring inside walls, including clever hooking tools and, when necessary, making small cuts into the drywall. The more invasive work they have to do, the longer the project will take and the more labor costs will add up. The wiring accessibility depends on the design of your house, which is why it’s helpful to schedule an electrical consultation before beginning work.

Does a New Wiring Increase Home Value?

If rewiring is necessary to pass a home inspection, it will make a home easier to sell, which will likely offer a solid return on investment. Especially if you’re investing in the cost of replacing knob and tube wiring or other outdated components. An upgraded electrical system improves safety, ensures code compliance, and supports energy-hungry features like whole-home cooling and EV chargers. While it may not grab attention like a new bathroom or renovated kitchen, a full rewire improves your home’s function and can be a key factor in successful inspections and home appraisals.
