How Much Does It Cost To Hire an Electrician vs. DIY?

Updated: May 25, 2024

You need some electrical work done, but you can't decide whether to DIY or hire an electrician. Here are a few tips that may help you decide.

There’s an old expression attributed to Benjamin Franklin: “Time is money.” That phrase carries a lot of weight when trying to decide if you should hire a contractor for electrical work or perform it yourself.

Here’s your guide to garage wiring.

Electrical contractors know how precious time is. They have a business to run and workers who need to be paid. They must generate revenue to cover expenses and make a profit.

As a homeowner, your time is also a commodity. If you have plenty of spare time and the knowledge and skills to tackle certain projects, you can save a lot of money compared to hiring an electrical contractor. On the other hand, if you’re busy with work and family, isn’t it worth your time to hire a professional to do the work quickly and safely? Maybe even before you get home from work?

Here we’ll get into the costs of several home electrical projects, and whether you should have them done by a pro or go the DIY route.

How Do Electrical Contractors Charge for Their Services?

Time and material projects

For small projects, many contractors keep things simple and charge their customers for time and materials. Every contractor will set a “small project” cost threshold that fits their individual business plan. Small projects generally cost less than $500.

The time and material method is also used when it’s impracticable to estimate the cost of a project ahead of time.

Bid projects

For larger projects, it’s more common for the contractor to submit a bid to the homeowner. To ensure competitive pricing, consumer protection advocates always recommend getting bids from more than one contractor. The bidding process takes more time, but it’s an effective method for selecting a contractor at the best possible price.

The bid documents should contain all the specifications for the project and the services included in the cost. To avoid any confusion, be sure the bid documents clearly detail all the work.

Service calls

Hourly rates vary in different regions, but you should expect to pay about $125 an hour for a licensed journeyworker electrician. If the project needs additional help, the contractor may also send an unlicensed apprentice electrician to the job site at a lower hourly rate of around $95.

In many regions, one licensed journeyworker electrician is authorized to personally supervise up to two unlicensed apprentice electricians at the job site. This helps reduce the labor costs for the customer, and gives the apprentices valuable experience they need to eventually obtain their journeyworker licenses.

Material markup and overhead

Contractors will often mark up the cost of materials as part of their business model. Like all costs, markup will vary by region, but contractors may charge 10% for overhead and as much as 40% for markup.

Markups of 20%, 30% or 40% might seem excessive, but it’s important to remember the contractor may warranty their workmanship for up to five years and materials for one year. The warranty is a written guarantee the contractor will come back and take care of specific issues at no additional cost.

Before selecting a contractor, be sure to inquire about their warranties. A low bid may seem attractive at first, but you might regret that decision if there is no warranty coverage.

Most Common Electrical Projects and How Much They Cost

The estimated costs listed below will vary by region and don’t include local fees for permits and inspections. The time it takes to complete a project will also vary depending on job site conditions. Mike Phiffner from South Side Electric in Bloomington, Minn. graciously shared a list of his most frequent homeowner projects.

  • Cost: $250.
  • These types of problems can usually be resolved in a couple of hours.

  • Bigger equipment and more time drive up the cost of this type of project.

Install wiring for an electric vehicle (EV) charging station
