Every year, homeowners pay unlicensed or underqualified electricians to do work that fails inspection, creates fire hazards, voids their homeowner insurance, and costs significantly more to fix than the original job would have cost done right. The electrical trade has a lower barrier to presenting as qualified than many other trades — anyone can show up with a truck and tools. Verification takes 10–15 minutes online and is the most important thing you can do before hiring. This guide covers the complete vetting process: state license database lookup URLs, what the Certificate of Insurance must include and how to verify it is real, the nine red flags that signal an unqualified contractor, and a 2026 pricing reference for common residential electrical projects.
State License Databases: How to Verify in Any State
Every state that licenses electrical contractors (nearly all do) maintains a public online database where you can verify license status, type, and any disciplinary history. The process: ask the contractor for their license number before the first visit. If they cannot provide a license number immediately, that is a red flag. Look up the license in your state database. Key state databases: Texas — TDLR at tdlr.texas.gov/LicenseSearch/ (search by company name, individual name, or license number; shows license type, status, expiration, and disciplinary actions). California — CSLB at cslb.ca.gov/OnlineServices/ (search by company name or license number C-10 for electrical). Florida — DBPR at myfloridalicense.com/DBPR/pro/index.html (search Electrical Contractor). New York City — NYC DOB at a310.nyc.gov (search by license number or business name). Illinois — IDFPR at idfpr.illinois.gov/DPR/Lookup/. Washington — L&I at verify.lni.wa.gov. Georgia — GPEC at verify.sos.ga.gov. For all other states, search Google: '[state] electrical contractor license lookup.' Confirm: (1) the license is active, (2) the license type is appropriate (Electrical Contractor at the company level, plus Master Electrician — some states require you to verify both), (3) the expiration date is in the future, (4) no disciplinary history entries.
Certificate of Insurance: What It Must Include
Before any electrician sets foot on your property, request a Certificate of Insurance (COI). The COI should be from a major insurance carrier (not a small specialty insurer you have never heard of) and include: General Liability Insurance — minimum $1 million per occurrence, $2 million aggregate for projects over $5,000. This covers property damage and bodily injury to third parties. Workers Compensation Insurance — required in most states when the contractor has employees. This protects you from liability if a worker is injured on your property. Without workers comp, an injured worker can sue the homeowner directly. The certificate should list you (the homeowner) as an Additional Insured and show your property address. This ensures the policy specifically covers work at your property. Contact the insurance company directly using the number on the certificate — do not use a number provided by the contractor — and verify the policy is active and in good standing. Certificate forgery is a known issue in the contractor space. An electrician who pushes back on providing a COI or becomes evasive about insurance is a contractor you should not hire.
9 Red Flags That Signal an Unqualified Contractor
- Cannot provide a license number immediately when asked — licensed electricians have it memorized
- Requests payment in full before any work begins
- Offers to skip the permit to 'save you money' — permits are required, not optional
- Price is 30%+ below all other quotes without explanation
- Cannot provide a Certificate of Insurance on same-day request
- No physical business address — only a cell phone number and Facebook page
- Will not provide the panel brand and model in the quote
- Uses back-stab outlet connections exclusively (a known failure point) rather than screw terminals
- Pressures you to decide same-day or lose the quoted price
Questions to Ask Before Hiring
Beyond license and insurance verification, the following questions reveal the most about a contractor's fit for your project. How many electricians will be on site — is it you personally, or a crew? If a crew, are they licensed employees or subcontractors? This matters for accountability. What panel brand are you planning to install? (For panel work.) A knowledgeable electrician answers Square D QO, Eaton BR, or Siemens — and explains their preference. A hedged answer ('whatever is available') is a yellow flag. Have you done this specific type of work (panel upgrade, generator installation, EV charger with panel upgrade) in the last 6 months? Ask for references from similar projects, not just general reviews. What is your warranty on workmanship? One year is the industry minimum; two years is excellent. How do you handle unexpected scope additions? You want a written change order process. What are your permit coordination and inspection procedures? The answer should be confident and specific. Have the inspector request a final sign-off before making final payment — the inspection protects you.
Fair Pricing for Common Electrical Projects (2026)
These are national average ranges. High-cost markets (NYC, LA, San Francisco, Seattle, Boston) typically run 30–60% higher. Lower-cost markets (rural Midwest, Deep South) may run 10–20% below these figures. Service call (first visit, diagnosis): $75–$150 trip charge plus $50–$100 per hour. Outlet replacement (existing location): $75–$150 each. Adding a new outlet (new circuit from panel): $250–$500 each. GFCI outlet installation: $100–$200 each installed. AFCI breaker upgrade (per breaker): $150–$250. 100A to 200A panel upgrade: $1,800–$4,000 all-in including permit and utility coordination. EV charger installation (Level 2, panel has capacity): $500–$1,500. EV charger with panel upgrade: $2,500–$5,500. Generator installation (standby, 18–22 kW, natural gas, standard site): $8,000–$14,000. Whole-home rewire (1,500 sq ft): $9,000–$16,000. Use these ranges as a sanity check against quotes — prices significantly below the bottom of these ranges warrant investigation.
Getting Three Quotes: Always get three written quotes for projects over $500. The quoting process itself reveals as much as the price — which contractor shows up for a site visit vs. quotes over the phone, which provides a detailed itemized quote vs. a single-line total, and which asks the right questions about your panel and planned loads. The cheapest quote is often the worst value once you account for scope exclusions, corner-cutting, and the cost of fixing problems later.
After the Work Is Done: Verify Before Final Payment
Before making final payment, verify: the permit inspection has passed and the permit is officially closed out (ask to see the inspection sign-off or verify online at your city building department portal), all work described in the contract scope has been completed (physically inspect each item), all replaced materials have been removed from your property (leftover wire, conduit, old panels), the electrician has provided documentation of the panel brand and breaker model (for insurance purposes and future reference), and any new outlet or circuit labels on the panel are accurate and legible. Paying the full balance before the permit inspection passes is a common mistake — the inspection is your final quality checkpoint that costs you nothing extra but gives you significant protection. If issues are found at inspection, the contractor is responsible for corrections at no additional cost while you are holding the final payment.
