Check certification and insurance
A serious electrician should be able to show the licenses, trade certifications, and insurance required for the work before giving you an estimate. Ask what standards they follow for residential installations and whether their policy covers both property damage and injuries on the job.
Request copies of the relevant documents and check their expiration dates. An expired policy or an electrician who refuses to share credentials is an immediate warning sign. You can also ask your home insurer whether the business meets any contractor requirements in your policy.
Compare three detailed estimates
A good electrician's estimate separates labor from materials and lists the work in plain language: number of outlets, breakers, fixtures, wire runs, permits, and the expected schedule. Be cautious of a single lump sum with no line items; it makes changes and quality impossible to evaluate.
Ask for the business's legal name and registration details, then verify them through your state or local registry. A legitimate company should have a track record, provide a written invoice, and be willing to explain who will perform the work. Do not trust a low bid from an uninsured operator.
Read neighborhood reviews and favor local coverage
Google reviews help you see whether an electrician actually serves your area. Read comments for details about punctuality, cleanup, troubleshooting, and communication, not just the star rating. Look for repeated work in nearby neighborhoods rather than a profile with vague, city-wide claims.
Proximity matters for emergencies too: when a breaker trips at night or a circuit fails on a weekend, a nearby electrician can usually respond sooner and charge less for travel. Choose someone who serves your neighborhood regularly and can return later for maintenance or an electrical upgrade.
