Electrical work can involve safety, permits and coordination with other trades. Compare the exact services a company publishes, then confirm who will perform the work and what documentation the job requires.
What to compare
Check experience with the specific job, service area, estimate terms, warranty information and scheduling. Ask whether permits or inspections apply and who is responsible for arranging them.
Describe the job clearly
Note the affected circuit, appliance or room, when the issue occurs and any recent changes to the property. Do not open panels or handle exposed wiring to gather more detail.
