Electricians do a fair amount of larger remodeling and new construction projects but also common residential projects including:
For cost information related to the above tasks, visit our Electrical Cost Guide.
A truly skilled, well-equipped professional with a truck full of parts that charges $100 an hour can be a much wiser choice than an inexperienced hack, working with inadequate tools and no parts, but charging much less. Often, more experienced professionals get the job done quickly with warrantied work.
2. Compare Travel ChargesRates reflect travel times. Travel charges can have a big impact on your costs and are in some ways easier to compare than hourly rates. Many electricians spend a third or more of their time navigating traffic on their way to a jobsite. Every contractor must find a way to pay for the expense of driving each day.
3. Bundle Repair Jobs TogetherWhen you feel it’s time to call a pro, review your list and then conduct a mini-inspection of your home. Look for faulty switches and dysfunctional or crowded outlets. When the electrician comes, you’ll save money and time by getting everything taken care of at once.
